1. a filter method, Gu be thing to be filtered is realized gas by a filter---Gu or liquid---be separated process, it is characterized in that:

  • in this process, apply between the filter core (3) of filter and shell (2) alternating voltage that alternative frequency is 10HZ ~ 50HZ, alternating voltage is set in >

    0 volt and in the scope of≤

    50 volts;

    Described filter core (3) is directly connected with the circuit producing this alternating voltage;

    During filtration, under the effect of alternating electric field, charged particle between filter core and shell moves repeatedly, because the quality of each particle is different, the speed dynamic at the flows by action of identical power is different, thus in certain space, the particle of different quality can be distinguished, the particle of these different qualities is successively distributed between filter core and shell.
