Abstract
PURPOSE: To permit easy breakage of filter cake which consists of impalpable powder by enclosing in a moment the total amount of the compressed air in a specific small amount restricted into a counter-current nozzle which is arranged on the filter purification side exceedingly close to the filter while opening a reverse washing automatic valve.
CONSTITUTION: The compressed air in an accumulator 30 which is filled beforehand up to a prescribed value from a compressed air source 33 through a primary piping 32 completes gushing out in a time far shorter than 0.3sec for example 0.03 sec from a reverse washing nozzle 27, and an automatic original valve 31 is closed, so only a specific amount flows. As a suction valve 23 is closed, the compressed air is enclosed into the back of a filter 44 in a moment. This air flows into a negative pressure hopper 6, accompanied by breakage and breakaway of cake.
