    专利说明:

    The invention relates to an apparatus for disinfecting high-pressure water, like a steam generator, by heating and heating to a temperature above 100 ° C, the apparatus comprising piping, at least one heating circuit temperature and pressure.
    A high-pressure water mist system is known in the art, which includes a high-pressure pump, piping and terminals for producing spray mist.
    The problem with some applications is that situations can arise where viruses and bacteria in pipelines and water, such as legionella, spread through the spray mist into the environment, causing health hazards to the environment and people, even life-threatening.
    In other track humidification applications, on the other hand, “cold” water at 20-35 ° C is not absorbed well enough by the track to be humidified.
    The problem is that there is no system or water-lubricated high-pressure pump with a spray system that achieves a pressure of more than 80 MPa for water with a temperature above 85 ° C.
    The object of the invention is to provide, after one high-pressure pump, N water in one or two stages heated to such a temperature o that there are no more living harmful = bacteria in the water, whereby spray mist can be used safely e.g.
    N for humidifying air energy efficiently as in a hospital environment.
    The system can also be used after reheating N as a steam generator for track humidification. The characteristic features of the present invention appear from the appended claim 1.
    The high-pressure hot water spray system according to the invention comprises a water piping and a high-pressure pump for creating a pressure of 2 to 25 MPa in the water piping, and supply means for spraying water as a droplet spray or steam. The system further includes at least one post-high pressure water heater through which the water piping passes to destroy viruses and bacteria in the water, such as legionella. Air and track humidification can be achieved hygienically without the risk of bacteria and legionella with heaters and control valves connected to a high-pressure mist system, including piping, stage 1 and / or stage 2 water heater, pressure means for pumping process liquid as air in heat exchangers or process. The supply means comprises several stages and nozzles for spraying water and further one or two water heaters.
    Multi-stage process: Advantageously and in clearly separated stages - the nozzles are high pressure nozzles with a pressure of 0.5 O 25 to 25 MPa, preferably 7 to 12 MPa. With the help of high-pressure nozzles, N water evaporates into the air stream with ideal efficiency while humidifying o air or process. After the high-pressure pump, the incoming process heat to the heat exchangers = heats the spray water, whereby the bacteria in the water N are destroyed. Water below 50 degrees may contain S 30 bacteria e.g. legionella.
    S> According to one embodiment, the high-pressure piping has one or two separate water heaters, each with its own temperature and pressure levels.
    The apparatus according to the invention is preferably used in the process industry, such as the paper industry in power plants, oil refineries and all condensing and dust binding processes.
    The apparatus according to the invention combines the processes of air conditioning technology, condensing technology, heating technology, thermodynamics and humidification.
    These unifying measures achieve significant savings in energy costs, space solutions, construction and equipment investment, deliveries, installation and operating costs.
    The invention will now be described in detail with reference to the accompanying drawings illustrating some embodiments of the invention, in which Figure 1 shows an existing basic solution with piping added with three control valves 4.1, 4.2 and 4.3. , Figure 3 shows an existing basic solution of a system according to the invention with piping added to a 1. O 25 and 2nd stage water heater (6 and 11), N Figure 4 shows an existing basic solution of a system according to the invention with piping added to a 2nd stage E water heater (11). Figure 3 shows a process diagram of the apparatus according to the invention with all its steps. According to Figure 2, the apparatus according to the invention comprises a water piping 5, spraying means for humidifying the air and / or the track, where part 12 is a humidification terminal. the equipment after the pump in the stage 1 heater heats the spray water to a temperature such that the bacteria and viruses in the wetting water are destroyed and this only happens when a sufficiently high spray water temperature is reached.
    The 1st stage water heater 6 in high pressure piping 6-8 MPa comprises water piping 5 and several piping components and for safe heating of high pressure water, 2-way valves with actuators 4.1 and 4.3, hot water coil 9, safety valve 8. Figure 2 shows a preferred embodiment of the equipment with high pressure pump 1 then the water is directed by means of a 2-way valve 4.1 to water heaters 6, where the high-pressure water is safely heated to the desired pressure of 60-80 degrees Celsius at 6-8 MPa.
    Temperature measurement 3.2 is used to monitor the temperature of the high-pressure water.
    If the water temperature at measuring point 3.2 is below 60 ° C (adjustable), direct the 2-way valve 4.3 to the water drain.
    When the water temperature at measuring point 3.2 is greater than or equal to 60 ° C (adjustable), the 2-way valve 4.3 controls the water humidification supply means 12. Figure 3 shows a preferred embodiment of the apparatus in which - after the high pressure pump 1 the water is controlled by the 2-way valve 4.1 O 25 for water heaters 6, in which the high-pressure water N is safely heated to the desired temperature of 60-80 ° C at a pressure of 6-8 MPa.
    The water is then directed by means of a = 2-way valve 4.2 to another water heaters 11, where N water is safely heated to a further higher desired temperature S of 120-160 degrees Celsius at a pressure of 6-8 MPa, where water N does not evaporate but is a liquid of about 120-160 * C temperature. 5 After the water heater, the pressure of the water heated in the water heater 11 is dropped in the pressure relief valve 7.1 to the desired pressure, whereby the hot water in the piping is evaporated in the supply means 12. The temperature measurement 3.2 monitors the temperature of the high pressure water 5. If the water temperature at measuring point 3.2 is below 60 ° C (adjustable), direct the 2-way valve 4.3 to the water drain. When the water temperature at measuring point 3.2 is greater than or equal to 60 * C (adjustable), control the 2-way valve 4.3 to the water spray supply means 12.
    In the apparatus, the mass flow of water mist can be adjusted with an accuracy of about 0.2 g / s by means of a nozzle system. Preferably, the nozzles included in the apparatus are non-drip high pressure nozzles with a droplet size of 0.5 to 5 according to the Sauter mean diameter method. Preferably, the high pressure pump used in the apparatus may be a water-lubricated high pressure pump that develops a pressure of about 8 MPa. In this case, the high-pressure hot disinfected spray water free of living organic organisms is efficiently absorbed into the air stream or track. Subsequent clear separate steps make the high-pressure water a spray mist similar to pure steam, which can replace O 25 with steam humidifiers with high investment and operating costs and lower efficiency than the now invented D apparatus. x a J. In another embodiment of the invention, a closed circuit is provided in the water piping. When N spraying is not used, the water from the high-pressure pump (e.g. 8 MPa) is led by means of 5 valves in a closed circuit, where the water is circulated through the heating circuit by a low-pressure pump (e.g. 2 MPa). In this case, the water in the water piping can be kept warm (above 55 ° C) and thus bacteria-free. When spraying is started, the valves of the high pressure pump and feeders are opened and the water in the water piping can be sprayed immediately without discharging the water into the sewer.
