Embodiment 1

[0030] see Figure 1-Figure 6 . This embodiment provides a device for regenerating a particulate matter trap. This particle trap regeneration device includes a tailpipe 5, a combustion cylinder 4, an ignition element 7, an atomizing nozzle 14, an air intake pipe 8, a fire baffle 1, an ignition plug 15, a heat insulation layer 2, and a first blocking sheet 41 , blocking cover 20 and hoop 9.

[0031] A tailpipe chamber 51 is formed on the tailpipe 5, a combustion chamber 42 is formed on the combustion tube 4, and an ignition chamber 72 is formed on the ignition member 7; one end of the tailpipe chamber 51 communicates with one end of the combustion chamber 42, and the other end of the tailpipe chamber 51 is closed; the combustion chamber The other end of 42 is used to communicate with the particle trap; the ignition element 7 is placed in the combustion chamber 42, and the side wall of the ignition element 7 is provided with a plurality of diffusion through holes. A plurality...

Embodiment 2

[0055] see Figure 7 . An embodiment of the present invention provides a regeneration device for a particle trap. The structure of the regenerating device of this particle trap is basically the same as that in Embodiment 1, the difference is that in this embodiment, the ignition plug seat 12 is arranged in the combustion cylinder 4, and the axial direction of the ignition plug seat 12 is in line with the The axis direction of the ignition element 7 is set at an included angle. Specifically, the axial direction of the ignition plug seat 12 and the axial direction of the ignition element 7 form an included angle of 90°.

[0056] Through the above-mentioned structure, it can form a turbulence effect on the airflow, make the fuel and exhaust gas mix more uniformly, further improve the combustion efficiency, and also facilitate the installation and adjustment of the product.

Abstract

The invention relates to a particle catcher regenerating device. The particle catcher regenerating device comprises a tail pipe, a combustion cylinder, an ignition part and an atomizing nozzle. A tailpipe cavity is formed in the tail pipe. A combustion chamber is formed in the combustion cylinder. An ignition cavity is formed in the ignition part. One end of the tail pipe cavity communicates withone end of the combustion chamber. The other end of the tail pipe is closed. The other end of the combustion chamber is used for communicating with a particle catcher. The ignition part is arranged in the combustion chamber. The sidewall of the ignition part is provided with a plurality of diffusion through holes. The ignition part is provided with an oil spray nozzle seat. The atomizing nozzle can extend into the ignition cavity through the oil spray nozzle seat. When the particle catcher regenerating device is in use, the tail pipe cavity is connected with the tail pipe of an engine, tail gas passes and gets into the regenerating device and the particle catcher in sequence to realize tail gas particle collection. The ignition part is provided with diffusion through holes. When gas is ignited in the ignition cavity, the heated gas is diffused into the combustion chamber through the ignition cavity so that the combusted gas can be more uniformly diffused to the particle catcher to achieve the purpose of uniform regeneration throughout the particle catcher.

Description

technical field [0001] The invention relates to a particle trap regeneration device capable of uniform heat transfer. Background technique [0002] As the exhaust emission regulations become more and more stringent, the particulate matter in the engine exhaust of various models needs to be further treated, and during the use of the particulate matter trap, the accumulated particulate matter in the particulate matter trap is increasing, causing the engine The back pressure of the engine increases, the power decreases, and the economy is reduced. The particulate matter trap regeneration device is to fully burn the fuel in the regeneration device, and the heat generated increases the temperature of the exhaust gas and generates a high temperature above 550°C to ensure the oxidation and combustion of the particulate matter in the particulate matter trap, thereby achieving the purpose of eliminating particulate matter. [0003] Existing regeneration devices for particulate matte...
