Abstract
The foam cleaning system for an electrostatic precipitator includes a source of a suitable detergent and means for introducing it into a foamer, a source of supply water which is piped through a water pressure reducing valve if necessary and then through a pressure gauge and solenoid valve control and through a suitable filter into the foamer, and a supply of compressed air which passes by suitable conduit through an air pressure regulator and solenoid valve control into the foamer. The detergent, water and air are suitably combined in the foamer and discharged therefrom as a foam into a manifold which will carry the foam to the electrostatic precipitators to be cleaned. The foam is introduced into a space provided at the top of the precipitator above the ionizer and collecting cell plates, between the inlet and outlet filters, and between the side wall of the precipitator. A drain is provided adjacent the precipitator. The top of the precipitator is filled with foam in a relatively short time until it is forced down the various plates in the ionizer and collecting cell at which time the foamer is turned off and the so introduced foam is permitted to penetrate and settle within the precipitator for a somewhat longer period of time. Rinsing water is then introduced into the top of the precipitator and the spent foam, collected contaminants and rinse water are collected in a suitable sump and disposed to a sewer, reservoir or the like. Preferably the rinse water manifold system is separate from the foaming unit.
