    regular maintenance in order for it to fi perform satisfactorily. Furthermore, there is a risk that the purified water may contain copper ions emitted from the electrodes.
    It is also known in the past to use lasers to purify water. For example, patent specification US4661264 describes a device for purifying water with laser. The construction differs greatly from the construction of the present invention. For example, the construction of the patent does not include directional lasers.
    U.S. Pat. No. 7,760,363 discloses a purification device for water which passes through a treatment chamber. The purification of the water takes place with the help of UV light and laser. In one of the embodiments of the patent specification, the treatment chamber consists of a serpentine-shaped channel. Figures in the patent specification show serpentine-shaped loops which are apparently opposite in relation to each other. However, the construction differs greatly from the construction of the present invention. For example, the construction according to the patent does not include a first laser which creates negative ions in the water and a second laser which creates positive ions in the water.
    The use of containers with a shape which allows reflections in walls and the like is already known. Patent specification US5 874741 describes a device for water purification where the water purification takes place by means of UV light. The water is treated in a container which has an elliptical shape. The construction differs to a large extent from the construction of the present invention. For example, the treatment of the water does not take place with opposite lasers.
    A further problem with known types of purification devices is that coatings are created on the walls of the purification device as well as in pipe systems and the like connected to the purification device. The coatings mean that the function of the treatment devices is completely or partially lost. The present invention and method means that the coating on walls and the like is eliminated or substantially eliminated. OBJECTS OF THE PRESENT INVENTION The main object of the present invention is to create a substantially more efficient purification device and method for purifying water than previously known purification devices and purification methods. Another object of the present invention is to create a water purification method with which the water is purified by laser. A further object of the present invention is to create a device and a method by which water is purified with laser beams directed towards each other. An even further object is to create a device and a method for purifying water with lasers of different nature where one creates negative ions and the other creates positive ions. It is a further object of the present invention to create a purification device which only needs to be maintained to a limited extent. Finally, it is a further object to create a method for purifying water which means that the inner surfaces of the cleaning device are self-cleaning.
    Detailed Description of the Invention The present invention will hereinafter be described in more detail with reference to the accompanying schematic drawings which, by way of example, show the presently preferred embodiment of the invention.
    Figure 1 schematically shows a device for water purification in accordance with the present invention.
    Figure 2 shows the present invention in more detail.
    Figure 3 shows an alternative embodiment of the present invention.
    Figure 4 shows an embodiment where the present purification device is used for purifying water from, for example, a pool or the like.
    Figure 5 shows an exemplary embodiment where the present purification device is used for desalination of seawater.
    Figure 6 shows an exemplary embodiment where the present purification device is combined with a filter.
    Referring to the figures and more specifically to Figure 1, a purification device 1 in accordance with the present invention is shown. The purification device 1 is preferably intended to be used for purifying the liquids of liquids such as water and the like. It is conceivable that the purification device can be used in specific applications where gases or a combination of liquid and gases are purified.
    The purification device 1 comprises at least one flow-through vessel (treatment vessel) 2 which comprises at least one internal space (treatment chamber) 3 which via at least one first opening 4 connects to at least one inlet duct 5 and via at least one second opening 6 connects to at least one outlet duct 7. When operating the purification device 1 flows a flow of liquid into the inner space 3 of the flow vessel 2 from the inlet channel 5 and out of the inner space 3 of the flow vessel 2 through the outlet channel 7.
    Preferably, the treatment vessel 2 is constituted by a spherical body 8. The volume of the inner space 3 in the spherical body 8 can vary to a large extent within the scope of the present patent application. The treatment vessel 2 is preferably wholly or partly made of titanium. It is essential that the inner surface 9, of the treatment vessel 2, is made of titanium or titanium alloy. It is conceivable that all or parts of the treatment vessel 2 are made of another material suitable for the purpose. In alternative embodiments, it is further conceivable that the treatment vessel 2 has a different shape which is suitable for the purpose.
    The inner surface 9 of the spherical treatment vessel 2 is preferably mirror-reflecting to enable laser light to be reflected towards the surface. The mirror-reflecting surface can be achieved by polishing (highly polishing) the surface 9.
    The shape and size of the inlet duct 5, the outlet duct 7, the first opening 4 and the second opening 6 may vary within the scope of the present patent application. Preferably, these have circular cross-sections. In alternative embodiments, it is conceivable that the shape of the cross-section on the inlet duct 5, the outlet duct 7, the first opening 4 and the second opening 6 has some other suitable object on the cross-section. The size of the inflow arena and the outflow area may vary within the scope of the present invention.
    The purification device 1 further comprises at least one control system comprising at least one control unit 10. The control unit collects information from at least one sensor 11 which senses the flow through the purification device. The sensor ll in the figure is placed after the treatment vessel 2. In alternative embodiments, the sensor ll can be placed in another place suitable for the purpose in the system. Furthermore, the purification device preferably comprises at least one second sensor 12 which is intended to detect, for example, the presence of microorganisms, the presence of impurities, the pH value of the liquid or another substance or the like. The sensor 12 may be a separate unit or be integrated with another unit such as one or both of the lasers or the control system.
    The cleaning device 1 comprises at least one first laser 13 and at least one second laser 14. The first laser 13 emits at least one first laser beam 15 and the second laser 14 emits at least one second laser beam 16. The first laser beam 15 and the second laser beam 16, which are emitted by the first laser 13 and the second laser 14, are directed inwards into the treatment vessel 2.
    Preferably, the first laser beam 15 and the second laser beam 16, respectively, are opposite, or substantially opposite to each other. The lasers 13 and 14 are preferably CO 2 lasers. Alternatively, another type of laser suitable for the purpose which is suitable for the purpose can be used. The lasers used in the present construction are energy efficient.
    In the embodiment shown, the energy consumption per laser is estimated to amount to approximately 12 - 16 W.
    The focal point 17 of the first laser beam 15 is regulated via at least one eyepiece 18 or the like. The focal point 19 of the second laser beam 16 is regulated via at least one second eyepiece 20 or the like.
    The distance between the first focal point 17 and the second focal point 19 is adjustable via the eyepieces 18 and 19. The distance between the two separate laser focal points 17 and 19 is controlled by the control system. The abstinence is determined, for example, by the conductivity of the water or liquid.
    The main feature of the present invention is that one laser creates (injects) negative ions into the water and the other laser creates (injects) positive ions into the water.
    The presence of both negative ions and positive ions in the water means that an efficient purification process of the liquid (water) is achieved and that an effective increase of pollutants in the water takes place. In order for ions to be created by the laser beams in the liquid (water), the liquid (water) must contain a certain amount of salt such as sodium chloride.
    Through an alternating method, the first laser 13 and the second laser 14, respectively, alternately emit negative impulse beams and positive impulse beams, respectively. When the first laser 13 emits negative impulse beams, the second laser 14 emits positive impulse beams. After a certain period of time, a change takes place so that the first laser 13 emits positive impulse beams and the second laser 14 emits negative impulse beams. The changeover preferably takes place within the interval of 22 to 30 seconds. Alternatively, the change can take place within a shorter time interval or a longer time interval.
    In a preferred embodiment of the present, the power of the laser beams is regulated by the control system so that there is a difference between the strength of the laser beams. This is done to create an unequal weight between the amount of positive and negative ions in the liquid (water). For example, the power difference between the laser beams may be in the range of one to forty percent. In a preferred embodiment of that of the present invention, the difference between the power of the laser beams is 10-20 percent. The substance weight between positive and negative ions varies so that during a certain period of time the amount of positive ions is higher than negative ions. In the next time period, the amount of negative ions outweighs the amount of positive ions. The changes mean that deposits do not form on surfaces in the system with which the liquid (water) comes into contact. This makes the cleaning device and the pipe system self-cleaning from particles that would otherwise get stuck on internal surfaces in the system.
    The control system of the purification device also comprises at least one circuit with which a pulsation of the laser light and a shift between positive and negative rays can be effected. The pulsating laser light can be achieved by means of an electrical circuit. The circuit for creating a pulsating and changing laser light may comprise a time switching means in accordance with, or a modified variant of, construction described in the Swedish patent specification SE516909.
    The present purification device comprises at least one function for filtering the water treated in the flow-through container. In the filter, flocs and the like are filtered (separated) from the treated liquid (the water). The filter consists of previously known technology, which is why it is not described in more detail in this patent application. The filter can, for example, consist of a combined sand and carbon filter. In alternative embodiments, it is conceivable that the filter consists of one or more filters of some other type of previously known type of water filter.
    Referring to Figure 4, an example of how the present purification device is used for purifying water such as pool water is shown. The clock shows how the purification device is connected via a pipe loop to the pool's ordinary pipe system or similar. The pipe loop is a sub-loop of the total pipe system in the plant or alternatively a separate pipe loop. The loop and the pipe system comprise a plurality of control valves with which the flow can be controlled in the loop and the ordinary pipe system, respectively.
    The laser purification process in accordance with the present patent application assumes that a certain amount of salt is present in the water to be purified. In a first step, therefore, salt is added to the liquid in the system if necessary. The salt is preferably sodium chloride. The salt is added in an amount which means that the salinity in the water amounts to a level in the range 0.2 to 1.0 ppm.
    Preferably, the salinity of the water is at a level of 0.4 ppm. The amount of salt added is regulated by the control system.
    In a second step, compressed air is supplied to the water (liquid). The compressed air is added via at least one line from a compressor. The air is compressed by the compressor to a higher pressure than the pressure in the liquid to which the compressed air is to be supplied. To prevent liquid from penetrating via the line to the compressor, in the event of any pressure spikes in the water line, the line to the compressor comprises at least one non-return valve. The volume of the added compressed air is regulated by the control system.
    The liquid (water) with the added (dissolved) salt and the air then flows via the inlet channel 5 into the flow vessel 2. As the water passes through the flow vessel 2, it is exposed to the first laser beam 15 and the second laser beam 16. The first laser beam 15 and 15, respectively, emitted in the flow vessel 2 the second laser beam 16 creates (injects) positive and negative ions into the liquid, respectively. Due to the presence of positive and negative ions in the liquid, an fl formation in the water (liquid) will take place.
    After the water has been exposed to laser light in the inner space 3 of the flow vessel (treatment vessel) 2, the water flows further out of the flow vessel 2 via the outlet channel 7 and further via the pipe system to at least one filter.
    The filter is intended to remove precipitated fl and the like from the water (liquid). The filter consists of a previously known type of filter. For example, the filter may include filtering materials such as sand and activated carbon. Alternatively, a second filter material and filter types suitable for the purpose can be used. The figure shows a filter unit with associated function for backwashing and the like.
    After filtration, the purified bag is led back from the loop to the piping system.
    Referring to Figure 5, a second example of how the purification device in accordance with the present invention can be used in desalination of water is shown. In the exemplary embodiment, the purification device is used for desalination of water. When desalination of water, at least one purification device is connected to at least one unit for desalination. The desalination unit can consist of a number of variants of previously known desalination technology. Figure 5 shows an exemplary form of the desalination device in which reverse osmosis is used to effect desalination of the water.
    The desalination step in Figure 5 is connected to the line system after the filter unit. The desalination step then comprises at least one pump with which a pressurization of the water (liquid) takes place.
    In the figure, the water is pressurized via a first pump and a second pump. The figure also shows a temperature control unit which can consist of a heating cartridge or the like. The pressurized water is introduced into a pressure chamber comprising at least a first space and a second space which are separated by at least one semipermeable membrane. The semipermeable membrane is designed to allow the relatively smaller water molecules to migrate through the membrane while the relatively larger salt molecules cannot migrate through the membrane. Upon desalination, the pressurized and heated water molecules will migrate through the membrane from the first space to the second space while the salt molecules will remain in the first space. Furthermore, the first space comprises a drain through which the saline water in the first space can be regularly discharged.
    Figure 5 also shows a function with which a backwashing of the membrane can take place. The figure also shows how only a part fl desolate flows through the desalination device. It should be noted that the exemplary desalination device and technology is only one of a number of conceivable variants of desalination devices and techniques that are conceivable to use.
    The present purification device can also be used in connection with purification of air.
    For example, it is conceivable that the water purification device is used to purify ventilation air.
    The purification of the air does not take place directly but indirectly. For example, purification of ventilation air can take place by spraying water into the air at a relatively higher height and allowing it to fall down through the air, which is to be purified, to a lower height where the water is collected. The collected water is then introduced into a pipe loop comprising a purification device 1 in accordance with the present invention.
    In an alternative embodiment, it is conceivable for the treatment chamber and the filter to be integrated in one unit.
    In the detailed description of the present invention, construction details which may be obvious to a person skilled in the art may have been omitted. Such obvious construction details are included to the extent required for a proper function of the present invention to be achieved. For example, components such as cabling, switching on and off, emergency stops, pipes with several components are included to the extent required in order to obtain a satisfactory function for the construction in accordance with the present patent application. Although certain preferred embodiments have been described in detail, variations and modifications within the scope of the invention may become apparent to those skilled in the art to which the invention pertains, and all of these are considered to fall within the scope of the appended claims.
    Advantages of the Invention The present invention has a number of advantages. The most obvious advantage is that the present purification device and purification method are significantly more efficient than previously known purification constructions and purification methods. Another advantage of the present method and apparatus in accordance with the present construction is that the construction reduces the need for chlorine additives in the water. An even further advantage of the present construction and method is that it reduces coatings on pipe systems connected to the purification device. It is also an advantage of the examined construction that it can be used to purify air. In addition, it is also an advantage that the purification device is energy efficient.
