Product parameters
P type backwash filter is a product developed and developed by our company on the basis of the introduction of foreign technology. It is an upgraded product of all kinds of vertical and horizontal dirt removers and filters. On the basis of the original filter, water flow guide device and drain outlet are added to make it an equipment that can automatically wash the dirt and automatically clean the filter components under the condition of no shutdown. Compared with the previous generation of filter, it avoids the need of system shutdown and time-consuming and laborious disadvantages when draining and cleaning the filter screen.

Working principle
p-type backwash filter is mainly composed of high-quality carbon steel cylinder, filter assembly, water flow guide valve and blowdown device. When the filter works, the water flow guide valve is in the open state, the water flows into the filter from the inlet, and is filtered to the outlet through the filter screen, and the impurities in the water are intercepted by the filter screen. When the filter needs to drain, close the water flow guide valve and open the drain valve. The water flows through the first half of the filter screen, one part of the water flows directly into the system after filtering, and the other part of the water flows from the outside of the filter screen to the inside, constantly flushing the dirt on the inner wall of the filter screen, and then discharging through the drain outlet, which plays the role of reverse automatic flushing the filter screen and removing the dirt. The whole process of backflushing and blowdown does not need to close the system and no person Clean the filter element and realize on-line blowdown.
