METHOD FOR REMOVING CHARGED PARTICLES FROM GAS FLOW Russian patent published in 2017 - IPC B01D35/06 B03C3/145 B03C3/40 

FIELD: gas industry.

SUBSTANCE: invention relates to methods for cleaning gases and can be used in power engineering, in ferrous and nonferrous metallurgy, cement, nuclear and other industries. Removal of charged particles from gas flow is performed by electric field of electric filter. To grip microparticles, variable electric field of quadrupole type is used. Variable field generates linear electrodynamic trap, its axis is perpendicular to direction of gas flow rate. In the trap charged particles are captured without depositing on electrodes and removal of trapped particles from gas flow along the axis of the trap by gravity and/or additional constant electric field.

EFFECT: higher degree of purification of gas and simplification of system for collecting microparticles.
