Description

[0002] At present, the mobile equipment for underground operation of coal mine still uses explosion-proof diesel engine as prime mover in large quantities.

[0003] In order to meet the above requirements, during the design and manufacture of new explosion-proof diesel engine, the tail gas treatment of explosion-proof diesel engine becomes the key direction. The traditional technology is to use water washing type tail gas treatment, which has the problems of low tail gas treatment efficiency, large volume of fire barrier, difficult cleaning after blockage, large water consumption, poor endurance, and deep secondary pollution caused by acid-base wastewater discharged into the air with tail gas.
