    Cleaning device The present invention relates to a cleaning device for cleaning and / or decontamination of a process engineering device, e.g. a column.
    Today, in a large number of process engineering systems, various process engineering equipment is used, the chemicals contained in or passed through these devices become heavily contaminated over time and / or cause heavy contamination of the device. Impurities such as production residues, lime, and the like reduce efficiency over time. This manifests itself, for example, by a reduced heat transfer, a reduced flow rate or otherwise also noticeable through corrosion.
    For this reason, it is essential that the process engineering equipment is subjected to a cleaning procedure at certain time intervals to effectively remove the deposits. This is usually done in the form of mechanical cleaning, but this is both time consuming and costly. In addition, such mechanical cleaning must often be carried out on an open appliance so that there is always a risk of contaminant residues entering the environment.
    It is also possible that the chemicals in the process equipment lead to the formation of gaseous harmful substances. If maintenance work is to be carried out on these devices, the device must first be disinfected.
    However, the process engineering equipment is usually a network of different types of equipment, so that the one to be cleaned or the equipment to be disinfected first has to be decoupled from the rest before cleaning. Cleaning, for example, can lead to the entire process technology being shut down for this period. Such a downtime is always expensive for the operator, so it is in his interest to keep downtime as low as possible.
    All in all, the object of the invention is to provide a cleaning device, which is characterized by a simple and inexpensive structure and which is characterized by
    and enables a reliable and inexpensive cleaning procedure. This object is achieved by a cleaning device according to claim 1. According to the invention, the cleaning device has a cleaning container with at least one inlet connection and at least one outlet connection, through which the cleaning container can be connected to the process engineering device and through which a cleaning liquid can be discharged. the cleaning container can be introduced into the process engineering equipment and / or removed from the process engineering equipment to the cleaning container, wherein a temperature control device for heating the cleaning liquid is included in the cleaning container.
    The process engineering device can be, for example, a column, a heat exchanger, a reactor or the like.
    A cleaning liquid is preferably arranged in the cleaning container, the type of cleaning liquid depending on the process-technical equipment to be cleaned or the expected residues in the process-technical equipment. Via the drain pipe of the cleaning container, which is usually designed in the form of a flange, the cleaning liquid can enter the process engineering devices via a preliminary line. To provide the required pressure pressure, a feed pump can be arranged between the discharge port of the pump container and the process engineering device, via which the cleaning liquid can be extracted from the cleaning container and introduced into the process engineering device. The feed pump can be applied directly or with the intervention of a feeding line to the discharge connection of the cleaning device.
    Via the inlet connector of the cleaning container, it is possible to transport cleaning fluid back into the cleaning container after one pass through the process engineering device. Thus, the cleaning device can be entirely formed as an encapsulated system, with the contaminated cleaning liquid only present in the cleaning container after completion of a cleaning process, which especially reduces the risk of contamination from pollutants harmful to the environment or the environment. health.
    The cleaning container has a filling volume in the range of 1,000 1 to 2,000 1, preferably between 1,300, so that the cleaning system can also be used to sufficiently clean large process-technical devices in particular, without the need for frequent replacement of the cleaning fluid. l and 1,700 1.
    The cleaning container can also have a substantially cylindrical shape, the side surface then preferably extending along a horizontal line. Regardless of the specific shape of the cleaning container, it has a length in the range of 1.0 m to 2.0 m, preferably between 1.2 m and 1.8 m and / or preferably a width in the range between 0, 5 m and 1.0 m, preferably between 0.7 m and 0.9 m.
    The length of the cleaning container is based on the longitudinal direction and the width of the cleaning tank in the width direction, the width direction being perpendicular to the longitudinal direction of the cleaning device. As far as a cylindrical cleaning container is concerned, the width essentially corresponds to the diameter.
    In a preferred embodiment of the invention, the cleaning container has at least two, preferably at least three, e.g. four inlet connections. These are preferably arranged side by side in a longitudinal line on the cleaning container. In a cylindrical cleaning container, the inlet connections are preferably arranged on the side face. The inlet nozzles usually have a flange connection, via which a return pipe can be connected detachably.
    In a preferred embodiment of the invention, the cleaning container has at least one temperature and / or one pressure measuring device.
    The temperature control device makes it possible to heat and preferably preheat the cleaning liquid to a specific temperature.
    Accordingly, the cleaning liquid can be introduced into the process engineering equipment at a temperature so that a high cleaning power is possible. Heating the cleaning fluid offers the possibility of carrying out the cleaning processes during the operation of the process engineering equipment. In this case, the cleaning
    liquid from the cleaning container into the process engineering equipment and from there into the process engineering method. To avoid thermal losses, the cleaning fluid can be preheated to a temperature that is essentially the temperature present in the process engineering equipment. With the help of the temperature measuring device it is possible to continuously monitor the temperature or the temperature trend. This also applies to the pressure or the pressure in the container. Such pressure monitoring is of special significance for safety-critical aspects.
    In addition to or as an alternative to a temperature and / or pressure measuring device, a level measurement can also be included in the cleaning container in a further development of the invention. For this purpose, different level meters come into consideration, the level meter preferably having a magnetic valve indicator. Magnetic valve indicators have a float with a built-in magnet system that transfers the liquid level to the magnetic valve indicator display without contact. This indicator has several steel valves arranged in a certain distance from each other, each of which has an inserted bar magnet. The float is also equipped with a magnet, in particular a permanent magnet, and leads to an adjustment of the magnetic valves as soon as the float is guided past the respective magnetic valves.
    The float is not present in the cleaning container, but is arranged in a separate container bypass line, the bypass line being preferably attached to the bypass connection of the cleaning tank with a flange connection. These bypass ports are located in an upper and a lower portion of the cleaning container. Instead of a level meter with magnetic valve indicators, other measuring methods can be used, e.g. ultrasonic measurement or differential pressure measurement.
    In order to make the cleaning container stable on the one hand and to be able to use it mobile on the other, the cleaning container is placed on a portable frame, wherein the cleaning device of the cleaning container is arranged substantially horizontally longitudinally or in the longitudinal direction. In a cylindrical shape, the outer surface extends essentially parallel to the floor or to the floor supports of the frame. The movable frame can preferably have stable floor supports arranged at such a distance from each other that the tongs of a fork lift truck can reach into the floor supports. Here the floor supports preferably have either a floor side groove or a cavity.
    In principle, different types of configurations can be considered as a temperature control device. However, the temperature control device is preferably in the form of a heat exchanger and thus has a tube bundle of a large number of individual tubes through which heating or cooling medium flows in operational condition and thereby heats or cools the cleaning liquid. Different types of heating or cooling medium are also under consideration, preferably hot water vapor. Water is particularly useful as a cooling medium.
    As already explained above, a temperature control device can be used for heating the cleaning liquid, on the one hand to increase the cleaning efficiency and / or to avoid heat losses during cleaning in the continuous operation of the process engineering device. However, it has also been shown that for certain cleaning processes the cooling effect of the temperature control device is of particular importance. For example for steam, e.g. water vapor is available, it can advantageously be used for cleaning the process engineering apparatus. The steam is supplied externally via a separate connection and therefore not via the cleaning container. In addition to steam, separate cleaning liquid is therefore also introduced into the process engineering device, the combination of steam and cleaning liquid provides the required cleaning effect. The mixture of steam, cleaning liquid and residues are then introduced into the cleaning tank via the inlet, whereby cooling and / or condensation of the returned mixture is obtained with the aid of the temperature control device. The cleaning liquid can be supplied from a separate container or from the cleaning container, a dilution of the cleaning liquid then starts continuously until it has to be replaced at the right time.
    The cleaning device with the temperature control is also suitable for the neutralization of acidic compounds. Then, for example, an acidic compound, e.g. phosphoric acid, can be withdrawn from the process engineering device and introduced into the cleaning container, in which case an alkaline, for example a soda solution, can be used instead of a cleaning liquid. The drain from the cleaning container will not be used in this case and is therefore not connected to the process engineering device. The reaction between the acid compound and the alkaline agent leads to a strong heat development. With the aid of the temperature control device, this heat development is counteracted with the aid of a cooling fluid in order to avoid critical temperatures and pressures in the cleaning container.
    The tube bundle is disposed within the cleaning container and preferably extends along the longitudinal direction at least 20%, preferably at least 40%, particularly preferably more than at least 60% of the length of the interior. A longer version of the tube bundle leads to a more even heating of the cleaning liquid, but at the same time also creates a greater pressure loss within the individual connected pipes. The length of the tube bundle is accordingly preferably based on the cleaning liquid and on the available discharge pressure with which the heating or cooling medium can be supplied.
    In a further development of the invention, the tube bundle connects on a first side to an inlet chamber and on a second side to an outlet chamber. Accordingly, the individual tubes of the tube bundle are fillable through one common inlet chamber and can be emptied through a common outlet chamber so that the heating or cooling medium can flow from the inlet chamber through the tubes of the tube bundle into the outlet chamber. For the specific formation of the tube bundle and the location of the inlet chamber and the outlet chamber, different design shapes are considered.
    According to a first preferred embodiment, the tube bundle extends the entire length of the cleaning container, the inlet chamber on a first side, e.g. end side, and the discharge chamber on an opposite side, e.g. front of the cleaning container.
    In a second preferred embodiment, the tube bundle has a bend so that the inlet and outlet chambers are side by side or on top of each other and the inlet and outlet connections on one common side, e.g. end side of the cleaning container. The bend is preferably a bend of 180 °. Alternatively, it can be a bend consisting of individual bend sections that together bend through an angle of 180 °, but are separated from each other by individual straight sections.
    Regardless of the specific design of the temperature control device, the inlet chamber and the outlet chamber each have a connector with a flange connection through which the heating or cooling medium is introduced into the inlet chamber or can be removed from the outlet chamber.
    In a preferred development of the invention, the temperature control device is modular and removably attachable to the cleaning container. Such an embodiment is particularly advantageous because the type of temperature control device can be adapted to the respective cleaning situation.
    For example, there may be a variety of different temperature controllers, which on the one hand have to do with the type of heating or cooling but also differ from each other according to the specific design of the tube bundle. For example, it is conceivable that the individual temperature controllers relate to different numbers of tubes in the tube bundle, different tube diameters or otherwise different lengths of the tube bundle. Alternatively, the temperature control device can also be completely disassembled and the cleaning device operated with a cleaning container without a temperature control device. For mounting and dismounting, the cleaning container is preferably provided with a heating flange, on which the temperature control device can be attached to the cleaning container.
    In a preferred development of the invention, the cleaning device is connected to a process engineering device, e.g. with a column, which connection is via the at least one inlet connection and via the at least one discharge port.
    In another aspect of independent interest, the invention also relates to the use of a cleaning device for cleaning and / or decontamination of the process engineering equipment with a cleaning device according to the invention, wherein the cleaning container is connected via the at least one inlet connection and / or is connected to the process engineering device via the at least one outlet connection, eg with a column. Another aspect of the invention of independent significance relates to a method for cleaning a process engineering device with a cleaning device according to the invention, wherein, in the course of the cleaning container, a cleaning liquid is contained in the process engineering device. is introduced, the cleaning liquid flows through the process engineering device and it cleans or removes deposits from the process engineering device.
    Various embodiments have been found to be particularly suitable for the method. According to a variant of the method referred to as a circulation method, the cleaning liquid is circulated from the cleaning container in a closed circuit through the process engineering device. This is preferably done by introducing the cleaning liquid through an inlet on an upper section and the withdrawal via an outlet on a lower part of the process engineering equipment. The process liquid returns to the cleaning container via the drain and can then be reintroduced into the process technical equipment via the inlet. As a result of the cleaning, the cleaning liquid becomes contaminated during the flow of the process engineering device, so that a mixture of cleaning liquid and deposits returns to the cleaning container.
    According to a variant of the method, called the cascade method, the cleaning liquid can also be used in an open circuit that flows through the process engineering device. Contrary to a closed circuit, the contaminated cleaning fluid is then not returned to the cleaning container via the drain. Such a method always results in a higher consumption of cleaning fluid. However, the device can always be cleaned with unused cleaning fluid.
    According to a variant of the method called the buoyancy method, in addition to the cleaning liquid, steam is introduced into the process engineering device, preferably in a lower part, via a steam connection. The water vapor then mixes with the cleaning liquid and heats it to the predetermined temperature. Accordingly, in such a method, an additional temperature control can in principle be omitted. Nevertheless, this is possible as a complementary use.
    The mixing of water vapor with the cleaning liquid can take place in the process engineering device. However, as an alternative, pre-mixing is possible. For example, water vapor can be added to the cleaning liquid in a water vapor supply line. The mixture of water vapor and cleaning liquid then rises in the process engineering device and is distributed over the surfaces. The mixture condenses completely and at least partially and precipitates on the surfaces. This can provide effective cleaning and removal of the deposits. The mixture then flows away with the incorporated deposits and accumulates in the lower part of the device. From here, the contaminated mixture can be discharged through a drain pipe. The particular advantage of this method is that the cleaning liquid with the water vapor can also reach parts of the device that are difficult to access, so that the amount of cleaning liquid required is reduced. At the same time, the presence of a steam system is also necessary.
    The individual variants of the method can also be combined with each other. A particularly useful combination is the recycle method and the boost method. Starting from the above-described embodiment of the recycle method, in addition to the supply of cleaning liquid to an upper part of the process engineering apparatus, water vapor is supplied, which is preferably supplied to a lower part. The cleaning liquid thus flows through the appliance from the top downwards, while the water vapor flows from the bottom to the top and thus goes against the direction of flow of the cleaning liquid.
    For this reason, this variant of the method is also referred to as a countercurrent method. The water vapor mixes in part with the cleaning liquid and thus leads to improved cleaning performance over the circulation process. The closed cycle also allows less consumption of cleaning fluid than in the buoyancy process because the water vapor in condensed state is led back into the cleaning container together with the cleaning fluid and can then be reintroduced into the device for cleaning .
    As an alternative to the countercurrent method, the two methods can also be used sequentially. Here, the cleaning liquid with water vapor is introduced into the device based on the buoyancy method. Subsequently, the introduced mixture of water vapor and cleaning liquid is used in the recycling process, whereby additional cleaning liquid may also have been added via the cleaning container.
    Using the above methods, it is possible to create a cleaning system which is composed with the cleaning device, the process engineering device and any lines between the process engineering equipment and the cleaning device. Work on an open process technology device or on a cleaning device that is opened as a result is therefore not necessary.
    It is preferred that the cleaning liquid is heated to a predetermined temperature and / or maintained at a predetermined temperature with the temperature control device before it is introduced into the process engineering device, the temperature preferably being between 20 ° C and 210 ° C. , preferably between 40 ° C and 180 ° C, and particularly preferably between 60 ° C and 160 ° C, eg between 60 ° C and 110 ° C. The heating or temperature control is usually done with the aid of steam, e.g. water vapor, which enters the temperature control device and thereby heats up the cleaning fluid. In such a case, the temperature control device is designed as a heat exchanger. It is alternatively or additionally possible to install temperature control equipment within the process
    technical device for heating the cleaning liquid to the predetermined temperature. In a preferred development of the invention, a sampling point for taking a sample of the cleaning fluid is possible. This sample can then be checked for the degree of contamination or the degree of contamination can be examined. If the degree of soiling between two consecutive samples or the degree of soiling of the cleaning liquid do not or only slightly differ from each other, the cleaning process can be canceled. Previously, a limit value has been set for the execution of the specified procedure. In the closed-loop method, this tapping point is preferably located between the process engineering device and the inlet of the cleaning container.
    In an alternative process with a meaning of its own, the cleaning container of the cleaning device is only coupled via the inlet to the process engineering device, in which an alkaline agent has been introduced into the cleaning container, whereby an acidic compound, e.g. phosphoric acid, is fed from the process equipment to the cleaning container where it reacts with the alkaline agent, whereby a cooling medium, for example water, flows through the temperature controller and thereby cools the interior of the cleaning container.
    The invention also relates to a process installation with at least one process engineering device, e.g. a column, a tank, a heat exchanger, a pipe or the like, in which a cleaning device according to the invention, in particular in the form of a closed liquid circuit, is connected to the process engineering device. Preferably, cleaning liquid is then provided in the cleaning container.
    All the features described above with regard to the design of the cleaning device as well as the composition of the cleaning fluids also apply to the process engineering device.
