している。[0003] This water purification device can be attached to any water tank such as a cooling tower or a fountain to purify water in the water tank. In addition, since the large foreign matter is removed by the dust removing section 53, the burden on the filtering section 55 can be reduced. Furthermore, in the case of backwashing one of the filtration tanks 551b also in the backwashing of the filtration unit, the three-way valve 552b is closed to supply water only to the filtration tank 551a.
By sending a part of the drainage of the water 51a to the filtration tank 551b and sending the remaining wastewater to the circulation pipe 554, the filtration tank 551b can be washed without stopping the circulation of the water. In other words, there is an excellent point that the backwash of the filtration tank can be performed without stopping the main pump.

も抱えていた。However, even in such a water purification apparatus, it is necessary to provide two filtration tanks in the filtration section 55, so that the filtration section becomes large, and the filtration tank 551a has a problem. Since a part of the discharged water is supplied to the other filtration tank 551b, the amount of circulating water is extremely reduced. If the flow rate is increased to prevent this, the load on the pump unit 54 increases, and the pump Part 5
4 also had a problem that the capacity had to be increased.

ストがより一層高騰することになる。When the water purifier is installed in a pool or the like in which sand or mud may be mixed, it is assumed that large foreign substances such as sand or mud are clogged in the dust collecting portion 53 and the flow rate is reduced. However, in the above-mentioned water purification device, a backwashing mechanism of the dust removal unit 53 (first filtration unit) is not considered.
If the dust removing section 53 is configured similarly to the filtering section 55, the overall size of the apparatus is further increased, and the capacity of the pump section 54 must be further increased, so that the running cost further increases.

A part of the circulating water flowing through the water pipe 21 is drawn into the flowing water pipe 21, and the service water drawn into the flowing water pipe 21 is based on the relationship between the pressure of the circulating water system A and the pressure of the washing water system B. Then, it flows only into the flowing water pipe 22a where the electromagnetic on-off valve 25 is opened, and is supplied to the strainer 2 as backwashing water. Then, the filter is backwashed in the strainer 2 and discharged from the drain pipe 25 together with foreign matter as washing wastewater.

図ることができる。Since the water purification system 1 is configured as described above, the following effects can be obtained. 1) Since the water purification system 1 of the present invention includes the strainer 2 as the first filtration unit for removing relatively large foreign matter and the second filtration unit for removing fine foreign matter, circulation of a cooling tower or the like is possible. Purify not only cooling water for factory equipment such as water and molds, but also water for pools, water for fountains, water in bathtubs, water in water tanks, etc. You can also plan. And the second
By disposing the strainer 2 as the first filtration unit in front of the filtration device 4 as the filtration unit, it is possible to prevent large foreign substances from adhering to the filter of the filtration device 3 and reduce the burden on the filtration device 3. It can be reduced to extend the cleaning ability and life. 2) It can be easily attached to any type of water tank of any existing equipment, and can purify and activate water in the water tank. When a water purification system has already been installed, the backwashing mechanism of the present invention can be provided by attaching a cleaning water system B to the existing water purification system. In other words, the water purification system of the present invention can be modified. 3) Since the washing water for backwashing can be supplied to both the strainer 2 and the filtering device 4, not only the filtering device 4 but also the strainer 2 can be backwashed. 4) In addition, since the cleaning water system B is provided separately from the main circulating water system A and the cleaning pump 8 is attached to the cleaning water system B, the main pump 3 of the main circulating water system A is stopped. The backwashing of the filtration device 4 and the strainer 2 can be performed without causing the backwashing. 5) At that time, the strainer 2 and the filtration device 4 are sequentially washed. That is, washing is performed in two stages,
Since it is set (programmed) not to be performed at the same time, the washing pump 8 only needs to supply a limited amount of washing water to either the filtration device 4 or the strainer 2, and the burden on the washing pump 8 Can be reduced, and the size of the pump can be reduced.
