Title:
METHOD FOR OPERATION OF DUST COLLECTION DEVICE, AND DUST COLLECTION DEVICE
Document Type and Number:
WIPO Patent Application WO/2011/152357
Kind Code:
A1
Abstract:
Disclosed are: a method for operating a dust collection device, in which the adhesion of high-resistant dusts onto an electrode in a pre-charging unit can be reduced to achieve stable charging and therefore the operation can be carried out at low pressure loss and with high efficiency; and a dust collection device. Specifically disclosed is a method for operating a dust collection device comprising a smoke path through which a gas can pass and additionally comprising a pre-charging unit (110) and a bag filter in this order from the upstream side of the smoke path, wherein the pre-charging unit (110) comprises an electrode which can charge dusts, a power source which can supply an electric power to the electrode, and a gas flow rate control unit which can set the flow rate of the gas that passes through the pre-charging unit at a predetermined value. The method comprises the steps of: applying a voltage to the dusts from the electrode to charge the dusts; and increasing the flow rate of the gas that passes through the pre-charging unit to remove the dusts that have been adhered onto the electrode.
