Abstract

The invention discloses a tail gas purifying device of an explosion-proof diesel engine. The tail gas purifying device comprises a shell, the shell comprises an outer shell body and an inner shell body, a heat insulation layer is arranged between the outer shell body and the inner shell body, a catalytic converter is arranged in the inner shell body, and the catalytic converter comprises a carrier and catalysts. Tail gas emissions of a mining explosion-proof diesel vehicle under a mine are reduced, modifying design and a series of heat insulation measures are carried out on the catalysts, and the surface temperature is made to be lower than the safety temperature of 150 DEG C.

Description

technical field [0001] The invention relates to the technical field of explosion-proof diesel engine tail gas treatment, in particular to an explosion-proof diesel engine tail gas purification device. Background technique [0002] Diesel engines have the advantages of high thermal efficiency, large low-speed torque and wide power coverage, so almost all construction machinery vehicles use diesel engines. Mine explosion-proof diesel vehicles belong to construction machinery vehicles, which are necessary machinery for power supply in mining and transportation. Due to the narrow underground space and poorer ventilation conditions than the ground, the exhaust gas of explosion-proof diesel engines contains CO, HC, NOx and other harmful gases and various solid particles, which are extremely harmful to the health of underground workers. According to the laws and regulations, the exhaust emission limit value of mine explosion-proof diesel engine: the volume concentration of CO is 1...
