Abstract

The invention discloses a device for eliminating a DPF oil injection regeneration flame. The device comprises a shell. A flame eliminating cavity is arranged in the shell. One end of the shell is provided with an air inlet, and the other end of the shell is provided with an air outlet. The air inlet communicates with an air inlet pipe capable of communicating with an automobile exhaust pipe. The air outlet communicates with a tail pipe. The inner wall of the shell is connected with multiple flow baffles in the length direction. The peripheries of the flow baffles are in sealed connection with the inner wall of the shell. The middles of the multiple flow baffles are each provided with a hole allowing flame airflow to flow therein. The center lines of the holes and the center lines of the air inlet and the air outlet are in the same horizontal line. The diameter of the holes in the flow baffles is gradually reduced in the direction from the air inlet to the air outlet. The device can eliminate the DPF oil injection regeneration flame and has the advantages of being reasonable in structural design, good in safety, free of electroplating treatment, capable of saving energy, environmentally friendly, capable of effectively reducing noise and the like.

Description

technical field [0001] The invention relates to the technical field of automobile tail gas treatment, in particular to a device for eliminating DPF fuel injection regeneration flame. Background technique [0002] With the increasingly stringent exhaust emission regulations, how to reduce emissions has become a hot issue in the internal combustion engine industry. DPF (particulate matter filter) is one of the important components to reduce particulate matter emissions from internal combustion engines, and is widely used in exhaust aftertreatment systems of various internal combustion engines. [0003] DPF is installed in the exhaust system of diesel vehicles to reduce particulate matter in exhaust by filtering. DPF captures particles through surface and internal mixed filter devices, such as diffusion precipitation, inertial precipitation or linear interception. After the DPF is used for a period of time, the particulate matter will accumulate more and more in the device, wh...
