[Prior art]

 In recent years, raw water is collected from rivers and lakes that are contaminated with microorganisms, algae, organic compounds and inorganic compounds. For this reason, in the tap water treatment plant, this raw water is subjected to various treatments, finally sterilized by introducing chlorine and then supplied to households and factories. However, due to the pollution of this water source and the deterioration of water storage tanks, water pipes, etc., the water quality is decreasing year by year. Cooling water for air conditioners, etc. and pool water, such as pool water, are reused from tap water, and are treated by various running water treatment devices and used many times. Various water treatment devices are used to reduce such water quality and save water. Examples of such equipment include ultrapure water production equipment for semiconductor production that sterilizes with ultraviolet light, and a compact ultraviolet light sterilization equipment. In these systems, an ultraviolet ray generating lamp is placed in the lamp protection tube that is made of a material that can transmit ultraviolet rays in the center of the water supply tube, and sterilization is performed by running water around the lamp protection tube. is there. Therefore, if it is used for a long period of time, scale and dust adhere to the lamp protection tube and the water supply tube inside the ultraviolet irradiation device.

[Problems to be solved by the device]

 However, each of the above methods has various problems. Since the ultrapure water production equipment for semiconductor production is an equipment for producing ultrapure water through various filtration devices and sterilization equipment, if the quality of water such as ultrapure water is not required, the equipment This eliminates the need for a part of the filtration device, leading to higher processing costs. Since each filter and the ultraviolet irradiation device are large in size, it is necessary to replace the filter in the filtering device, replace the ultraviolet ray generation lamp in the ultraviolet irradiation device, or use the filter for a long period of time. Dust and water stains adhere to the lamp protection tube, and in order to clean it, the ultrapure water production system must be disassembled and must be manually operated, which is time-consuming and maintenance-intensive. There are problems such as large scale.

Further, a small sterilizer using only ultraviolet rays can sterilize microorganisms and viruses, but cannot remove foreign substances. As with the ultrapure water production system described above, dust and water stains adhered to the water supply pipe and lamp protection pipe during long-term use, and the device was disassembled and cleaned to remove these. In order to do this, it has to be done manually, and it takes time to process it, and there are problems with labor costs.

Furthermore, when the treated water treated by the conventional running water treatment device is used as cooling water in a cooling tower such as an air conditioner, there is a problem that red water is produced or water stains are accumulated and accumulated in the water pipe. .

Therefore, the present invention solves such a problem and downsizes and improves various flowing water treatment devices, and can supply water of water quality suitable for the application by selecting, replacing, and combining filters. Also, maintenance can be easily done by cleaning dust and dirt adhering to the inside of the water supply pipe of the ultraviolet irradiation device and the ultraviolet ray generation lamp, the manufacturing cost and installation cost of the device are low, and the cost of running water treatment is low. The purpose is to provide a running water disinfection device that prevents the generation of red water and the adhesion and accumulation of dust, water stains, etc. in the water pipe, and treats running water that has lost foreign matter, germs, and viruses. is there.

[0009]

【Example】

 Next, details of the present invention will be described based on embodiments. FIG. 1 is a principle diagram of a running water treatment using clean water and gray water as raw material water of the present invention. In the figure, tank A or the like stores water to be treated, such as tap water, gray water, or seawater. B is a pump for feeding the same, C is a device for treating the water to be treated sent from the pump B, in particular, various impurities contained in this liquid are filtered. It is a filtering device for doing. D, which is set after the filtering device C, is an ultraviolet irradiation device in which ultraviolet rays kill microbes, viruses and other substances. Then, the magnetic flux irradiating device E provided as necessary gives magnetic flux to the water to activate the running water, and the water is supplied to the outside from the treated water withdrawal section F. It should be noted that, as shown in the principle diagram of such a effluent sterilization process, there is no transfer capacity for supplying the effluent water to the effluent sterilizer itself in the raw water intake part H such as well water, spring water, and tap water. In this case, the supply means such as pump B may be used. When using the tap water which is treated by a local public body and supplied as water supply, the supply means such as pump B is not always necessary.

Next, in order to explain the details of these devices as a whole, in the filtration device shown as C in the figure, various foreign substances, ions, water-soluble organic compounds and the like contained in water are removed. For removing foreign substances, use a membrane such as a filter, sand, activated carbon for odor, ion exchange resin for ion removal, and reverse osmosis membrane for water-soluble organic compounds. Thus, it is possible to perform multi-stage filtration treatment by combining one or more of these depending on the use of water. In addition, the material of the filter 1 should carry or adsorb antibacterial substances such as silver, copper, zinc, iodine and antibacterial substances, or be kneaded or woven into the material of the filter 1 etc. May be. In these filtering devices C, a filter 1 is set in the main body of the filtering device C as shown in the figure, and a flow path is determined so as to pass through the filter 1 in the cross-sectional direction. The type that is supplied from, and flowed to the outlet is adopted. This filtered water is supplied to the next ultraviolet irradiation device D.

In the ultraviolet irradiation device D, microorganisms, viruses, etc. are killed. For this purpose, a lamp that emits ultraviolet rays of visible light or less is used, and preferably a wavelength of 250 nanometers to 270 nanometers is generated. What you do is better. Although low-pressure lamps, medium-pressure lamps, high-pressure lamps, etc. are used for this purpose, it is preferable to use low-pressure lamps, and the metals enclosed in the lamps are mercury and xenon. There is a large amount of. A lamp protection tube 3 which is shown by a dotted line in the drawing and covers the ultraviolet ray generating lamp 2 (not shown) is made of synthetic resin or quartz glass capable of transmitting ultraviolet rays.

And, as such an ultraviolet irradiation device D, a device as shown in the principle diagram is basically adopted. That is, there is a passage around the ultraviolet irradiation device D or a part of the ultraviolet irradiation device D that continuously flows while receiving the ultraviolet light emitted from the ultraviolet ray generation lamp 2 (not shown), and sterilizes this while irradiating the ultraviolet ray in the flowing process. To do. However, as will be described later, due to the relationship between the outer case 4 and the ultraviolet ray generating lamp 2 housed in this device, this device deteriorates in irradiation efficiency due to deterioration of the ultraviolet ray generating lamp 2. In addition, various kinds of deposits may adhere to the surface of the lamp protection tube 3 between them to block the irradiation of ultraviolet rays. Therefore, the ultraviolet ray generating lamp 2 can be freely taken out from the outer case 4. For example, it is preferable that the right or left cap 5 shown in the figure be removed and the ultraviolet ray generating lamp 2 inside can be taken out integrally with them.

In the magnetic field irradiator E, a magnetic field is applied to water to activate the water and prevent water molecules from aggregating with each other, thereby preventing adhesion of water stains in the water pipe and generation of red water. Moreover, it also delays the deterioration of water pipes. A permanent magnet, an electromagnet, or the like can be used as the device for generating the magnetic field lines. In this principle diagram, the magnetic field irradiation treatment is performed after the ultraviolet irradiation, but it may be provided before the ultraviolet irradiation treatment, but it may not be provided depending on the water quality. The running water treated in this way can be supplied as drinking water or industrial water if the raw water is tap water, or can be reused as water for cooling towers or pools if it is medium water.

In this pipe, the pipe 12 extended from the outer case 4, the pipe 12 extended from the filtration device C, the filtration device C and the extended pipe 12 are configured by screwing a screw nut 13 or the like. In addition, the pipe 12 at the outlet is also connected to the pipe 12 in the outlet direction by a screw nut 13, and by operating both screws, it is possible to remove the ultraviolet irradiation device D from the mount G. By performing this together with the operation of the shape fitting 10, it is possible to take it out easily. If one of the caps 5 of this device, for example, the cap 5 on the right side in the figure, can be easily removed and the lamp itself can be removed together, the lamp can be replaced and cleaned. It is extremely convenient for
