Dust collecting method by bag filter

Abstract

Abstract PURPOSE:To efficiently peel off even solid substances having high adhesion strength and carry out stable dust collection continuously by using sludge incinerated ashes as a release assisting agent to heighten the solid substance dropping off efficiency during the process of dust removing from a bag filter. CONSTITUTION:Dust collecting process to capture water-adsorptive solid substances in a waste gas 4 by a filtering cloth of a bag filter 7 after the waste gas 4 is led to a dust collecting chamber and dropping off process to drop the captured solid substances off are repeated. To heighten the solid substance dropping efficiency during said dropping off process, a sludge incinerated ashes 6 are used as a release assisting agent. As a result, for example, even solid substances which have high water-absorptivity and adhesion strength such as neutralized salts produced in dechlorination of the waste gas are separated effectively and stable dust collection is carried out continuously. Further, sludge incinerated ashes are used effectively and the cost for a release assisting agent is lowered as well.
