Abstract

The invention discloses a burner meeting the requirement of efficient regeneration in a low-temperature condition of a diesel particulate filter (DPF). The burner comprises a shell body, a combustion cavity, a gas inlet flow guide mixer, an inner combustion sleeve and a first-level outer combustion sleeve, and the combustion cavity, the gas inlet flow guide mixer, the inner combustion sleeve and the first-level outer combustion sleeve are arranged in the shell body. The gas inlet flow guide mixer is connected between the combustion cavity and the first-level outer combustion sleeve. The inner combustion sleeve is arranged in the first-level outer combustion sleeve. A nozzle is installed on the combustion cavity and is connected with an oil spraying pipe, and at least two sets of ignition devices are installed in the combustion cavity. A second-level outer combustion sleeve is connected to the tail end of the first-level outer combustion sleeve. The inner combustion sleeve, the first-level outer combustion sleeve and the second-level outer combustion sleeve are each provided with a plurality of air vents. The burner is compact in structure and convenient to disassemble, assemble and maintain, ignition failure can be avoided, the whole combustion process has a better heat effect, and combustion is sufficient.

Description

technical field [0001] The invention relates to a burner, in particular to a burner used in a selective catalytic conversion system of a diesel engine, which satisfies the high-efficiency regeneration of a particle trap DPF under low-temperature working conditions. Background technique [0002] At present, the rapid development of motor vehicles is accompanied by serious air pollution, showing the characteristics of regional complex. The air pollution in many big cities has changed from soot-type pollution to combined soot and motor vehicle pollution, and a few megacities have clearly shown photochemical smog-type (ie, motor vehicle exhaust) air pollution. Therefore, the research on diesel vehicle exhaust emission pollution control technology is extremely important and urgent. [0003] Particulate matter in diesel vehicle exhaust emissions is also a major pollutant. Particulate matter treatment technology mainly reduces particulate matter in exhaust by means of capture. In...
