Abstract

An electric filter has a chamber or case (1), through which the air or other gas to be cleaned is directed by means of a fan (4). An ionisation device has been arranged for the gas to be cleaned, the device consisting of one or several ionisation electrodes (9) and counter electrodes (10). An electrostatic field is formed by positive and negative electrodes (13, 14), of which the plate-like collector electrodes (14) are at least partly of glass or corresponding material and on which there tend to accumulate from the air or other gas to be cleaned the impurity particles which have received a charge from the ionisation device. There acts as the collection electrodes (14) a water film continuously flowing over a plate made of glass or material reacting to water in the same fashion as glass. Thus the dry and solid particles such as quartz or carbon dust contained in the gas to be cleaned are carried along with the water film without rebounding from the electrodes in exchanging their original charge for a charge with the same sign as that of the collection electrodes. In the direction of the upper edge of the solid plates of the collection electrodes (14) there are arranged for directing a water current to the plate water leading parts, for example pipes (15) having small holes or longitudinal apertures for a water current.
