Description

Technical field: [0001] The invention relates to the field of air purification, is mainly used in the field of tail gas post-treatment, and in particular relates to a maintenance-free diesel particle electric catcher. Background technique: [0002] Entering the National VI emission stage of road vehicles and the National IV emission stage of non-road vehicles, it is inevitable to use DPF / GPF products as the best treatment method for PM particulate matter in the vehicle after-treatment system. However, due to the constraints of the structure of DPF / GPF, various ash, metal shavings, sulfate and other substances produced after active and passive regeneration cannot be discharged from the wall-flow structure carrier of DPF / GPF, which will gradually lead to the exhaust system. The pressure rise will eventually cause the pressure of the exhaust system to be too high, and it is necessary to stop and clean the DPF / GPF carrier frequently, so that it can regain the ability to improve ...

AI Technical Summary

Problems solved by technology

However, due to the constraints of the structure of DPF / GPF, various ash, metal shavings, sulfate and other substances produced after active and passive regeneration cannot be discharged from the wall-flow structure carrier of DPF / GPF, which will gradually lead to the exhaust system. The pressure rise will eventually cause the pressure of the exhaust system to be too high, and it is necessary to shut down frequently to clean the DPF / GPF carrier, so that it can regain the ability to capture and reduce the cumulative back pressure of the DPF / GPF carrier

[0003] As the accumulated back pressure of DPF / GPF becomes higher and higher, the overall performance of the engine will be negatively affected or even directly damaged; shutdown cleaning of DPF / GPF not only requires specific cleaning tools but also takes a long time for a single cleaning and maintenance

Diesel mechanical DPF exhaust particulate matter treatment device, the DPF structure is prone to clogging, which will cause damage to the engine cylinder

[0004] At present, the existing diesel exhaust electrostatic adsorption products in the market have no practical structural design. The high-voltage power supply terminal and the corona wire are inserted from the end of the dust collection cylinder, and the high-voltage insulator is fixed on the front and rear gas outlet covers. When the high-voltage insulator must be disassembled, it is easy to cause damage to the high-voltage insulating parts. This damage is irreversible, and eventually leads to the overall insulation failure of the system or creepage phenomenon, so that the electric capture effect of the whole set of products fails. Excellent product design Frequent removal of high voltage insulators must be avoided

For example, the patent No. CN201921149267.1 is an exhaust gas purifier, which has a poor structure and is difficult to disassemble and clean. Every time it is disassembled and maintained, the high-voltage insulator must be disassembled, and the dust collection is extremely single cylinder structure, and the attachment area of ​​exhaust particles is small. , In addition, a single corona wire will also cause insufficient electric field strength inside the cylinder and affect the particle collection effect

[0005] Therefore, it is necessary to design a purifier that eliminates clogging, does not require disassembly of the high-voltage insulator, enhances the electric field strength, and prolongs the capture time.
