Mine dust removing systems mostly use wet dust collectors at present, according to the latest national emission standard, it is difficult to meet the emission requirements. Although the traditional bag filter can meet emission requirements, the water content of the particles is high in the mine, and the filter bag usually has the phenomenon of condensation, sticking to bags, and dust cleaning difficulties during use. Therefore, the experimental system was designed for low-pressure pulse dust cleaning of plate-frame microporous membrane dust collector, and the influence of different cleaning parameters on cleaning performance was studied, including the number of injection holes, injection distance, injection pressure and pulse injection time. And the optimal working conditions were selected to test the effect of the filter plate under the condition of powder attachment. The results show that the number of injection holes, injection distance and injection pressure have effects on the peak pressure, and the effect of pulse injection time on the peak pressure is implicit. The optimal conditions for the pulse cleaning operation parameters of plate-frame filter is 10 x Phi 5 injection hole, the injection distance of 20 mm, the injection pressure of 0.30 MPa, and the pulse injection time of 100 ms. On this basis, the cleaning effect of the filter plate with powder test is better, and the dust stripping rate phi was 92.9%, which is higher than 81%. The optimized plate-frame type dust collector has a better cleaning effect, indicating that the feasibility and applicability of pulse dust cleaning in plate-frame type dust collector have been improved.
