A kind of horizontal wet electrostatic precipitator moisture film forming apparatus
Technical field
The present invention relates to a kind of horizontal wet electrostatic precipitator moisture film forming apparatus, belong to mechanical field.
Background technology
It is in plate shape collection based on plate shape dust collecting electrode that the dust collecting electrode of electrostatic precipitator, particularly horizontal-type electrostatic dust collector, which is,
One plate or a diameter less steel wire with end points are set as discharge electrode, then in discharge electrode between dirt pole
Sun (+) pole or the moon (-) pole apply high voltage, bring it about corona (corona) electric discharge, make the particle sample material band of inflow
Electricity, charged particle moves the principle of simultaneously adsorption removal by electrostatic force to dust collecting electrode in continuous electric field.
The electrode of wet cottrell is cleaned with water, and traditional mode has:Intermittence injection and fine liquid (mist
Shape) continuous injection.
