Abstract

FIELD: methods of gasses purification used for gasses purification from fine dispersion electrical conduction particles of soot in particular. SUBSTANCE: row of plates with holes is mounted in series on the way of gas flow, speed of which is decreased to 1.5 m/s, and electrical current pulses are fed to the plates with from plate to plate interval equal to gas passing time duration. Additionally plates are subjected to vibration directed across gas flow so, that to coincide pulse action end with motion of corresponding plate downward and that holes of successive plate at the moment are not laying on one line with holes of previous one. Feeding of current pulse to plate facilitates fixation of impurities particles on it and end of current action - facilitates the particles release from the plate and their movement downward, where bunker-collector is located. EFFECT: increased quality of purification.

The invention relates to the purification of gases, mainly from fine electrically conductive particles, in particular, from soot. In accordance with the invention, in the path of the gas flow, the speed of which is reduced to 1.5 m / s, a series of plates with holes are installed in series and current pulses are applied to them with an interval from plate to plate equal to the gas passage time. Additionally, the plates are brought into oscillatory motion across the gas flow so as to combine the cessation of the pulse with the movement of the corresponding plate to the bottom and so that the holes of the subsequent plate at this moment do not lie in line with the holes of the previous plate. The supply of a current pulse to the plate contributes to the fixation of particles of contaminants on the plate, and the cessation of its action - to the separation of particles from the plate and their movement to the bottom, where the storage hopper is placed.
