Next, an embodiment of the present invention will be described with reference to the drawings.
As shown in FIGS. 1 to 4, a water purification unit 1 according to an embodiment of the present invention includes a water purification means 10, an engine generator 50 that supplies electric power to the water purification means 10, the water purification means 10, and engine power generation. And a container 60 for storing the machine 50.

First, the structure of the water purification means 10 is demonstrated based on FIG.
The intake pump 11 is a submersible pump attached to the tip of the intake hose 31 and is introduced into a pool, a well, a river, and the like so that raw water such as pool water, well water, and river water can be taken. The other end of the water intake hose 31 is connected to the raw water tank 13 through the primary filter 12. Therefore, the raw water taken by the water intake pump 11 is temporarily stored in the raw water tank 13 after dust and the like are removed by the primary filter 12.

  The raw water tank 13 and the raw liquid side of the hollow fiber membrane module 15 are connected by a pipe 32. The raw water transfer pump 14 is interposed in the pipe 32, and the raw water in the raw water tank 13 is introduced into the raw liquid side of the hollow fiber membrane module 15 by driving the raw water transfer pump 14. The raw water introduced into the stock solution side of the hollow fiber membrane module 15 is filtered through the hollow fiber membrane in the hollow fiber membrane module 15 to remove bacteria such as Escherichia coli and viruses. The filtrate is discharged from the filtrate side of the hollow fiber membrane module 15.

  As the hollow fiber membrane, a microfiltration membrane or an ultrafiltration membrane may be used. However, if a hollow fiber membrane with a pore size of about 0.02 μm is used, it is possible to achieve both high separation performance (for example, water quality with a turbidity of 0.1 or less) and high water flow performance. It is.

  The filtrate side of the hollow fiber membrane module 15 and the inlet of the activated carbon module 16 are connected by a pipe 33. Therefore, the filtrate discharged from the filtrate side of the hollow fiber membrane module 15 is introduced into the introduction port of the activated carbon module 16. From the filtrate introduced into the introduction port of the activated carbon module 16, organic substances, pigments, turbidity, odor, oil, and the like are removed by the activated carbon filter in the activated carbon module 16. The filtrate that has passed through the activated carbon filter is discharged from the outlet of the activated carbon module 16.

  The discharge port of the activated carbon module 16 and the water purification tank 18 are connected by a pipe 34. A chlorine injection device 17 is connected to the pipe 34. Therefore, the chlorine discharged from the discharge port of the activated carbon module 16 is sterilized by being injected with chlorine from the chlorine injector 17 while being transferred through the pipe 34. And it is temporarily stored in the water tank 18 as purified water.

  A pipe 35 is connected to the water purification tank 18, and a water tap 20 is attached to the other end of the pipe 35. A water supply pump 19 is interposed in the pipe 35, and the purified water in the water purification tank 18 is transferred to the water tap 20 by driving the water supply pump 19, so that purified water can be supplied from the water tap 20.

  Further, the pipe 35 is branched, and the end of the branched pipe 35 is a purified water outlet 21. The purified water outlet 21 can be directly connected to other devices and facilities that need to be supplied with purified water, and can supply purified water to them.

  In addition, the combination of the hollow fiber membrane module 15, the activated carbon module 16, and the chlorine injection | pouring apparatus 17 is equivalent to the water purifier as described in a claim. Since the raw water can be purified by the hollow fiber membrane module 15, the activated carbon module 16, and the chlorine injecting device 17, purified water that can be used as drinking water or domestic water can be supplied. As a water purifier, you may comprise as a combination of another filter etc., if it can purify | clean raw water and can produce | generate purified water.

Further, the water purification means 10 includes an air compressor 22.
The pipe 36 connected to the air outlet of the air compressor 22 is bifurcated, one pipe 37 is connected to the pipe 32 connected to the raw solution side of the hollow fiber membrane module 15, and the other pipe 38 is hollow. It is connected to a pipe 33 connected to the filtrate side of the thread membrane module 15. In addition, a pipe 39 is connected to the pipe 32 between a connection portion with the pipe 37 and the raw water transfer pump 14. The other end of the pipe 39 is opened as a drain port. In addition to the pipe 32, a pipe 40 is connected to the stock solution side of the hollow fiber membrane module 15. The other end of the pipe 40 is connected to the pipe 39. Further, the pipe 33 and the pipe 40 are connected by a pipe 41.

The pipes 37, 38, and 41 are respectively provided with automatic opening / closing valves 37v, 38v, and 41v so that they can be opened and closed. In addition, an automatic on-off valve 39v is interposed in the pipe 39 between the connection part with the pipe 32 and the connection part with the pipe 40. Further, an automatic on-off valve 40v is interposed in the pipe 40 between the connection portion with the pipe 41 and the hollow fiber membrane module 15. Further, an automatic on-off valve 33v is interposed in the pipe 33 between the connection portion with the pipe 41 and the activated carbon module 16.
As the automatic opening / closing valves 33v, 37v to 41v, air operated valves, electromagnetic valves, or the like are used.

  The air compressor 22, the pipes 36 to 41, and the automatic opening / closing valves 33 v and 37 v to 41 v constitute a cleaning unit that cleans the hollow fiber membrane of the hollow fiber membrane module 15.

As shown in FIG. 6, the water purifier 10 purifies raw water and cleans the hollow fiber membrane in the following procedure.
(1) First, from the state where all the automatic open / close valves 33v, 37v to 41v are closed, the automatic open / close valve 33v and the automatic open / close valve 40v are opened, and the raw water transfer pump 14 is driven to remove the raw water in the raw water tank 13 from the hollow fiber. It introduce | transduces into the stock solution side of the membrane module 15. FIG.
(2) After the raw water overflows from the pipe 40, the automatic open / close valve 40v is closed to start filtration. The filtrate that has passed through the hollow fiber membrane module 15 passes through the activated carbon module 16, is injected with chlorine by the chlorine injection device 17, and is stored in the water purification tank 18 as purified water. Purification of raw water is performed in such a procedure.

When the raw water is purified as described above, the filtration capacity of the hollow fiber membrane module 15 gradually decreases due to the suspension of the raw water in the hollow fiber membrane as the filtration time elapses. Therefore, the water purification means 10 next cleans the hollow fiber membrane.
(3) First, the raw water transfer pump 14 is stopped, and then the automatic open / close valve 33v is closed to stop filtration. Next, the air compressor 22 is operated to open the automatic open / close valve 38v and the automatic open / close valve 39v, and compressed air is introduced into the filtrate side of the hollow fiber membrane module 15. At this time, the filtrate in the filtrate side and in the hollow fiber membrane is pushed out to the stock solution side through the hollow fiber membrane and discharged to the outside through the pipe 39.
(4) Thereafter, the air compressor 22 is stopped, and the automatic open / close valve 38v and the automatic open / close valve 39v are closed. Then, the automatic open / close valve 41v is opened to evacuate the air in the hollow fiber membrane module 15.
(5) Next, the automatic open / close valve 41v is closed, the automatic open / close valve 40v is opened, and the raw water transfer pump 14 is driven to introduce the raw water in the raw water tank 13 into the raw liquid side of the hollow fiber membrane module 15.
(6) Next, after the raw water transfer pump 14 is stopped, the air compressor 22 is operated to open the automatic open / close valve 37v, and the compressed air is introduced into the raw liquid side of the hollow fiber membrane module 15. Thus, the hollow fiber membrane is washed with bubbles generated on the stock solution side.
(7) Finally, the air compressor 22 is stopped and the automatic open / close valve 37v and the automatic open / close valve 40v are closed. Then, the automatic opening / closing valve 39v is opened, and the raw water in the hollow fiber membrane module 15 is discharged from the pipe 39 to the outside. The hollow fiber membrane is washed through the above steps.

  After completion of the washing steps (3) to (7), the automatic open / close valve 39v is closed, the automatic open / close valve 33v is opened, and the process returns to the water purification step (1) again.

Thus, the adhering matter adhering to the hollow fiber membrane can be removed by the cleaning means and its performance can be recovered, so that purified water can be supplied continuously. In particular, it is possible to supply clean water for a long time without worrying about the operation time at a refuge in a disaster.
In addition, although the production | generation of purified water stops during a washing | cleaning process, since purified water is stored in the purified water tank 18, purified water can be supplied even during a washing | cleaning process. Therefore, water supply is not interrupted.

  The water purifying means 10 is provided with a control device 23 (see FIGS. 1 and 2). The control device 23 is connected to the intake pump 11, the raw water transfer pump 14, the feed water pump 19, the air compressor 22, and the automatic open / close valves 33v, 37v to 41v. The control device 23 purifies the raw water and forms a hollow fiber membrane. Each of the cleaning steps is automatically performed at predetermined time intervals. That is, the control device 23 operates the cleaning means at predetermined time intervals and automatically repeats purification of raw water and cleaning of the hollow fiber membrane.

  Thus, since the hollow fiber membrane is automatically washed by the control device 23, the user is not conscious of washing the hollow fiber membrane. Therefore, after the user puts the water intake pump 11 into a pool, a well, a river, etc., drives the engine generator 50, and operates the control device 23 to start the water purification means 10, the water tap 20 can be used at any time. You can get purified water from Thus, the user's operation becomes easy. Therefore, there is no need for a person who has received a special course on the operation of the water purification unit 1, and anyone can operate the shelter.

Note that the control device 23, the water intake pump 11, the raw water transfer pump 14, the water supply pump 19, the air compressor 22, and the automatic opening / closing valves 33 v and 37 v to 41 v are operated by electric power supplied from the engine generator 50.

Therefore, these members can be pulled out from the container 60 (see FIG. 1).

  With such a configuration, maintenance work such as replacement of the cartridges of the hollow fiber membrane module 15 and the activated carbon module 16 and supply of chlorine to the chlorine injector 17 can be easily performed. In particular, the general hollow fiber membrane module 15 is vertically long and requires a space in the height direction for the replacement operation of the cartridge. However, if the cartridge is pulled out from the container 60, there is nothing to block the upper portion of the hollow fiber membrane module 15. The cartridge can be replaced easily.

  In addition, inside the container 60, a slide device 63 that can slide in the horizontal direction on the bottom surface thereof is provided separately from the slide device 61. Further, a door 64 is provided on the side wall of the container 60, and a member installed in the slide device 63 can be pulled out from the container 60 by opening the door 64. An engine generator 50 is installed on the slide device 63. Therefore, the engine generator 50 can be pulled out from the container 60 (see FIG. 3).
