Abstract

The invention discloses a disassembly-free back-blowing purification device for a diesel particulate trap. The device comprises T-shaped port valves, an air blowing device and a particulate collecting device. The air blowing device is formed by an air compressor and an air storage bottle. The inlet end and the outlet end of the particulate trap are connected with the two T-shaped port valves respectively, and the particulate trap is provided with a differential pressure transducer and a temperature sensor. The particulate collecting device is connected with the outlet end of a T-shaped port through a flange and comprises a safety valve and a quick dismounting device. Through cooperative use of the air blowing device and a controller, the disassembly-free back-blowing purification device for the diesel particulate trap can discharge ash and particulate matters in the diesel particulate trap from a tail gas inlet end on the premise that a carrier of the diesel particulate trap is not disassembled, back-blowing purification of the carrier of the diesel particulate trap is achieved, the ash and particulate matter cleaning efficiency of the diesel particulate trap is greatly improved, and the use cost of a diesel engine is reduced.

Description

technical field [0001] The invention belongs to the technical field of after-treatment of motor vehicle exhaust, and in particular relates to a disassembly-free back-blowing and purification particle trap used for purifying diesel engine exhaust. Background technique [0002] With the increase of car ownership year by year, the pollution caused by automobile exhaust to the environment is becoming more and more serious. Among them, the pollution caused by the particulate matter of diesel engines is particularly prominent. higher requirements. Particulate filter is the most effective technical means to reduce particulate matter emissions from diesel engines. The particulate filter can capture the particulate matter in the exhaust gas. Gradually deposited on the surface of the diesel engine will cause the exhaust of the diesel engine to be blocked, the exhaust back pressure will increase, and the working efficiency of the particle filter will decrease, which in turn will reduc...
