ELECTRIC FILTER FOR PURIFICATION OF GASES Russian patent published in 2004 - IPC

FIELD: thermal power stations; cement and other industries.

SUBSTANCE: the invention is dealt with the electric filters for purification of gases and may be used thermal power stations, in cement and other industries. The invention ensures high efficiency in purification of gases from a dust, that contains of a lot of finely dispersed particles with the dimension less than 1 micron by increasing the currents of emission of electrons (ions) per a unit of length of the corona- forming electrodes. It is achieved due to the fact that in then electric filter for purification of gases the corona-forming electrodes are made so, that they form a uniform body of rectangulars in series connected to each other under an angle of 0° up to 90° relative to each other. The length of a zone of connection of rectangulars makes from 0.01 up to 0.5 against the length of each of them. On the shortest sides of each of two coherent rectangulars there is a sharpened wave.

EFFECT: the invention ensures high efficiency in purification of gases from a dust with a lot of finely dispersed particles of less than 1 micron size.
