Novel bag filter

The utility model relates to a novel bag filter which comprises a bag filter body, the bag filter body comprises an upper box body and a lower box body which are vertically connected together, the upper box body is provided with a plurality of air inlet pipes communicated with a blowing pipe, the air inlet pipes are provided with pulse electromagnetic valves, the pulse electromagnetic valves are electrically connected with a pulse controller, and the bag filter body is provided with a differential pressure gauge. One air guide pipe on the differential pressure gauge is communicated with an inner cavity of the upper box body, the other air guide pipe on the differential pressure gauge is communicated with an inner cavity of the lower box body, and air outlets are symmetrically formed in the left side and the right side of the upper box body. During operation, the differential pressure gauge can detect the use effect of the filter bag in the filter bag, so that the blowing and cleaning frequency can be better c
