Abstract

When collecting electrode walls are cleaned by rapping blows, a discharge of dust is prevented in that the aligned collecting electrode walls which are arranged one behind the other in the direction of gas flow are cleaned at the same time in all fields, the associated gas passages on opposite sides are shut off at the same time and an entraining gas stream is caused to produce in said gas passages a gas flow which is opposite to the normal direction of gas flow.
