Novel electrostatic-DEP deduster

A provided novel electrostatic-DEP deduster comprises an electricstatic dedusting part and a dielectrophoresis filter part, and an air outlet of the electricstatic dedusting part is connected with an air inlet of the dielectrophoresis filter part; the dielectrophoresis filter part is composed of a DEP purification processing unit; the DEP purification processing unit comprises M DEP purification electrode plates which are in the shape of a hollow cylinder and are in concentric sleeving connection; each DEP purification electrode plate comprises a DEP electrode comprising an anode and a cathode which are oppositely arranged, and the DEP electrode captures particles in air exhausted by the dielectrophoresis filter part through dielectrophoresis force. The novel electrostatic-DEP deduster filters off large-particle dust of inlet air through the electricstatic dedusting part and filters off small particles especially dust capable of entering lung through the dielectrophoresis filter part, so as to realize total-range comprehensive removal of dust particles. The dielectrophoresis filter part employs the dielectrophoresis principle for filtering dust, so that the novel electrostatic-DEP deduster is low in energy consumption, small in pressure loss and low in running cost.
