Abstract

PURPOSE: To eliminate the clogging of a filter and enhance shake-down capacity by removing a dust collected in a filter charged by a charging apparatus by washing.
CONSTITUTION: D.C. high voltage is applied between a discharge electrode 31 and an earth electrode 32 of the charging apparatus 3 to generate corona discharge and, thereby, a dust in a passing gas is charged. Subsequently, the gas is passed through the main filter 41 to remove the charged dust. The main filter has, for example, a structure suspending plural wool like fibers and the charged dust is collected by electrostatic attraction acting force other than mechanical filtering action. When air passing loss of the main filter 41 is increased, a recirculation pump 45 is started intermittently and a washing liquid is sprayed from spray nozzles 44 to flow down and remove the collected dust. When the washing liquid in a storage tank is concentrated by the dust, it is exchanged.
