Abstract
Description
Technical Field
[0001] The utility model relates to the field of automobile emission, in particular to a particle trap shell. Background Art
[0002] With increasingly stringent environmental regulations, reducing particulate matter in diesel engine emissions has become an important technical challenge. As an effective emission reduction device, particulate filters (DPF) are widely used in diesel engines or gasoline engines. However, after long-term use, traditional particulate filters will cause engine power to drop due to the accumulation of particulate matter. In order to solve this problem, it is usually necessary to replace the entire particulate filter, which not only increases maintenance costs but also may lead to waste of resources. Utility Model Content
[0003] In view of the above situation, in order to overcome the defects of the prior art, the purpose of the present utility model is to provide a particle trap housing, which has the advantage that there is no need to replace the particle trap, but only needs to disassemble the particle trap housing and take out the middle ceramic part for high-temperature combustion to remove the captured particulate matter, thereby reducing maintenance costs and increasing the service life of the particle trap.
[0004] The above technical objectives of the utility model are achieved through the following technical solutions:
[0005] A particle trap housing comprises a first shell and a second shell, wherein the first shell is symmetrical to the second shell, a particle trap body is matched and embedded between the first shell and the second shell, a fastening assembly is provided between the first shell and the second shell, a plurality of exhaust channels are provided on the first shell and the second shell close to the particle trap body, a ceramic filter element is matched and embedded in the plurality of exhaust channels, a plurality of filter channels are penetrated inside the plurality of ceramic filter elements, and a plurality of honeycomb filter holes are penetrated on the outer walls of the plurality of ceramic filter elements.
[0006] By adopting the above technical scheme, during operation, the exhaust gas is filtered and discharged through the particle catcher body. During the exhaust gas discharge process, the exhaust gas will pass through the exhaust channels on the inner walls of the first shell and the second shell, and the particulate matter in the exhaust gas will be adsorbed by cooperating with the ceramic filter element to achieve reasonable emission standards. The filter channel set in the hollow inside of the ceramic filter element can increase the particle adsorption surface to avoid blockage caused by the accumulation of particles and affect the exhaust. The setting of multiple honeycomb filter holes on the ceramic filter element can improve the exhaust efficiency. When the ceramic filter element adsorbs a certain amount of particles, the personnel can disassemble the first shell and the second shell, and take out the ceramic filter element for high-temperature combustion until the captured particles are completely burned. Then, the embedded assembly is performed, and the particle catcher body is reassembled. The recycling of the ceramic filter element increases the service life of the particle catcher body.
[0007] Further configuration: the ceramic filter cores are all made of high temperature resistant ceramic materials.
[0008] By adopting the above technical solution, the ceramic filter element made of high-temperature resistant ceramic material has certain corrosion resistance and high-temperature resistance, thereby increasing the service life of the ceramic filter element.
[0009] Further configuration: the surface of the ceramic filter element is coated with a catalytic coating.
[0010] By adopting the above technical solution, the catalytic coating coated on the surface of the ceramic filter element can improve the combustion efficiency of particulate matter and increase the service life of the ceramic filter element.
[0011] It is further configured that the fastening assembly includes a clamp sleeved between the first shell and the second shell, and a fastening screw is threadedly connected between the clamps.
[0012] By adopting the above technical solution, the clamp provided between the first shell and the second shell, and the fastening screw provided on the clamp, the fastening between the first shell, the second shell and the particle catcher body is ensured, thereby ensuring the stability of the operation.
[0013] It is further configured that the outer side walls of the first shell and the second shell are both coated with an anti-rust coating.
[0014] By adopting the above technical solution, the anti-rust coating applied on the outer sides of the first shell and the second shell plays a certain anti-rust role, thereby improving the service life of the first shell and the second shell.
[0015] It is further configured that the inner side walls of the plurality of exhaust pipes are coated with a heat insulation coating.
[0016] By adopting the above technical solution, the heat-insulating coating coated on the inner wall of the exhaust pipe plays a certain heat-insulating role, avoiding damage to the first shell and the second shell caused by long-term operation, and improving the service life of the first shell and the second shell.
[0017] In summary, the utility model has the following beneficial effects:
[0018] When the utility model is in operation, the exhaust gas is filtered and discharged through the particle catcher body. During the exhaust gas discharge process, the exhaust gas will pass through the exhaust channels on the inner walls of the first shell and the second shell, and the particulate matter in the exhaust gas will be adsorbed by cooperating with the ceramic filter element to achieve reasonable emission standards. The filter channel arranged in the hollow inside of the ceramic filter element can increase the particle adsorption surface to avoid blockage caused by the accumulation of particulate matter affecting the exhaust. The arrangement of multiple honeycomb filter holes on the ceramic filter element can improve the exhaust efficiency. After the ceramic filter element adsorbs a certain amount of particles, the personnel can disassemble the first shell and the second shell, and take out the ceramic filter element for high-temperature combustion until the captured particulate matter is completely burned. Then, the embedded assembly is performed, and the particle catcher body is reassembled. The recycling of the ceramic filter element increases the service life of the particle catcher body.
