摘要： The backwash type particulate filter according to the present invention is constituted by a gas permeable ceramic filter with a plurality of bores, the one ends of which open to gas inlet ports and the other ends of which open to gas outlet ports and the inner surfaces of the bores being used for filtration surfaces, and a NOx catalyst carried on the outer surface of the ceramic filter. Accordingly, the NOx catalyst is isolated from the influence of heat caused by burning the soot in the exhaust gas from a diesel engine collected on the filtration surfaces, thereby maintaining its catalytic function for a long time. The soot in the exhaust gas is effectively removed with the ceramic filter and the hazardous gas components in the exhaust gas with the NOx catalyst, respectively.
