Document Type and Number:
WIPO Patent Application WO/2016/002661
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide an exhaust purifier (1) which makes it possible to minimize unnecessary pressurized air consumption and improve particulate matter removal efficiency. An exhaust purifier (1) for removing particulate matter adhered to a NOx catalyst (14) by injecting pressurized air from an air injection nozzle (16) into a housing (13) of a catalyst reactor (12) in which the NOx catalyst (14) serving as a catalyst is positioned, wherein the pressurized air is injected by performing an opening/closing operation of an injection valve (17) in a soot blower (15) for supplying the pressurized air into the housing (13) of the catalyst reactor (12) on the basis of exhaust flow velocity (Ve).
