<p>An electrostatic dust collector has a chamber through which a gas to be cleaned is directed by a fan. A precipitating device in the chamber includes ionization electrodes and counter-electrodes upstream of an electrostatic field formed by positive and negative electrodes. The negative electrodes serve as collector electrodes for accumulating impurity particles from the air being cleaned and comprise a water film continuously flowing over a plate made of glass or other insulating material reacting to water in substantially the same fashion as glass. Pipes extending in the direction of the upper edge of the collector electrodes have apertures for directing a water film onto the plates and is connected to a negative pole so that the water film has a negative charge.</p> |
