EXHAUST GAS CLEANING FILTER AND PRODUCTION METHOD OF FILTER ELEMENT

摘要

PROBLEM TO BE SOLVED: To provide an exhaust gas clarifying filter which can be manufactured at a low cost and can efficiently catch particulate materials in the exhaust gas.

SOLUTION: In the exhaust gas cleaning filter for filtering the particulate materials contained in the exhaust gas, either one of a filter element which is made by charging particles obtained by calcining sewage sludge incineration ash or the filter element of a porous body obtained by molding pelletized sewage sludge incineration ash to a prescribed shape and then calcining, or their combination is used as the filter element of the filter. Thereby the particulate materials in the exhaust gas can be efficiently caught and the filter can be manufactured at a low cost.
