Self-cleaning wedge wire screen filter screen application: Filtration of industrial water, seawater, food, pharmaceutical, and other light chemical industrial wastewater and circulating water, and filtration treatment of emulsion regeneration, waste oil, and liquid raw materials. In metallurgical industry, petrochemical industry, power plant water supply, and drainage and circulating water system and liquid medium filtration. Continuous casting water system, blast furnace water system, high-pressure water descaling system for hot rolling, emulsion system, closed water circulation system, and liquid medium filtration system.
When the water enters the wedge wire filter cartridge from the water inlet, the impurities are intercepted on the inner wall of the filter cartridge, and the filtered clean water flows out from the water outlet. When the impurities on the inner wall of the filter screen accumulate more and more, and the pressure difference at the inlet and outlet of the self-cleaning filter reaches the preset value, reaches the cleaning time or manual prefabrication, the filter will start the self-cleaning process. The whole self-cleaning process includes two steps:
Open the automatic blowdown valve located on the self-cleaning filter.
The motor drives the cleaning brush in the filter screen, and the impurities intercepted by the filter screen are discharged from the blowdown valve. The system does not cut off during cleaning. The whole operation process of the self-cleaning filter is controlled by an intelligent control box equipped with a filter screen. The control mode can be differential pressure, time, manual, and PLC control.
