Electric rotary back-washing two filter rotary back-washing strong sewage two screen overview

The two filter system is purified water to keep dirt, condenser water chamber are often clean condition, ensure the normal operation of the rubber ball rubber ball recovery rate, improve an indispensable device. Our environment is more serious, rivers, lakes and other water quality pollution is particularly prominent. Therefore, the cooling water circulating system in more widespread use of the stationary and rotating suction type two two mesh, has shown its shortcoming. I plant is the production of power auxiliary equipment sentinel plants, through in last few years continue to seek the views of users and two screen repeated trial production and continuous improvement, retaining the old product component structure, increased the electric device, increasing the strong discharge device, so that the two filter structure and the use of a more complete, and widely used in6MW to300MW thermal power plant cooling water circulating system, by the vast number of new and old customers of praise. Rotary back-washing strong sewage two filter structure and working principle

Electric rotary type two filter structure such as Figure1, which is mainly composed of:⑴the stainless steel net shell core for transmission mechanism for speed reducer. Strong discharge devices and other components.

Working principle: after trash rack and a filter filtration of the circulating water still contains a lot of suspended matter and impurities such as sediment, after circulating pump in the two screen is then filtered, when the suspended substance in water, plastic film and other impurities in the surface of the screen is attached to a certain number, filter and pressure differential increases to a predetermined value ( control system general for the 500mmH2O column ), the start control system use, discharge mechanism to work, the attachment from the two filter, to stay within the differential pressure is restored to its normal ( general≤ 400mmH2O column ) control mechanism to close, move in circles, thus completing the filtering pollution discharge process. Users can also choose the timing of discharge.
