METHOD OF CLEANING GASES FROM DUST AND ELECTROSTATIC PRECIPITATOR FOR ITS IMPLEMENTATION Russian patent published in 2017 - IPC B01D35/06 B03C3/08 B03C3/40 

FIELD: technological processes.

SUBSTANCE: electrostatic precipitator comprises a housing, in which one or more fields are located, each field comprises several channels (3). The channels (3) comprise planes with gas-permeable precipitation electrodes (1) made of tubular elements. The gas-permeable plane of corona electrodes (2) is arranged between them at an equal distance. Shutters (4) and diaphragms (5), located in the channels in staggered order, have the geometric form of a concave cycloid and are made in the form of paired interceptors. The rear edges of the interceptors are in the plane of the corona electrodes, the front ones - in the plane of the precipitation electrodes, and are installed perpendicular to them. The distance between two adjacent diaphragms (5) in the channel (3) is equal to twice the gap (2H) between the planes of the precipitation electrodes. A gaseous flow (7) changes the motion direction from the sinusoidal (8) to the circular (9), passes through the corona discharge zone, where dust particles receive the maximum electric charge, then enters the zone of the quasihomogeneous electrostatic field (6), where the dust particles precipitate intensely. The gaseous flow cyclically and sequentially changes the direction of its circular motion, returns to the sinusoidal motion, passing stepwise through the entire length of the electrostatic precipitator channel.

EFFECT: improving gas cleaning quality.
