Efficient filtering equipment

The efficient back-blowing filtering equipment comprises an efficient back-blowing device and a filter, the interior of the filter is sequentially divided into a clean material area, a back-blowing area, a filtering area and a discharging area from top to bottom, and the efficient back-blowing device comprises a back-blowing air inlet header pipe, back-blowing air branch pipes, a back-blowing air automatic control device and a back-blowing air distribution device. The blowback air inlet header pipe is simultaneously connected to a plurality of blowback air branch pipes and an automatic control device; each automatic control device is connected with each blowback gas distribution device, the adjacent blowback gas branch pipes are distributed on the blowback gas main pipe at equal intervals, and each blowback gas distribution device is connected with one blowback gas branch pipe; and a nozzle is arranged on the lower side of each blowback air distribution device. The reverse blowing device has the advantages th
