The dust collecting filter of the present invention may include: a first filter medium that is bent into a corrugated shape and forms a plurality of bent portions; a plurality of first electrodes disposed on one surface of the first filter medium along the corrugated shape of the first filter medium and to which a high voltage is applied; and a plurality of second electrodes disposed along the corrugated shape of the first filter medium so as to be spaced apart from each other between the plurality of first electrodes and are grounded.

An engine tail gas dust removing system has a tail gas dust removing system inlet, a tail gas dust removing system outlet, and a tail gas electric field device. The engine tail gas dust removing system has a good dust removal effect, and can efficiently remove particulate matters in engine tail gas.

A method for reducing dust removal electric field couplings includes the following steps: selecting a ratio between a dust collection area of a dust removal electric field anode and a discharge area of a dust removal electric field cathode to be 1.667:1-1680:1. A dust removal electric field anode and/or dust removal electric field cathode size is selected so that the number of electric field couplings is less than or equal to 3. The number of electric field couplings is reduced, electric field energy consumption is low, electric field coupling consumption for an aerosol, water mist, oil mist and loose smooth particulate matter is reduced, and electric field energy is saved.
