A New Vehicle Exhaust Gas Treatment Device

Abstract

The invention discloses a novel automobile exhaust gas treatment device and belongs to the technical field of automobile manufacturing. The novel automobile exhaust gas treatment device comprises at least two exhaust gas treatment modules, a gas inflow module, a gas exhaust module and a positioning module. One end of each exhaust gas treatment module is connected with the gas inflow module in a sealed manner, and the other end of each exhaust gas treatment module is connected with the gas exhaust module in a sealed manner. The top portion of each exhaust gas treatment module is further fixedly connected with the positioning module. The gas inflow module, the gas exhaust module, the exhaust gas treatment modules and the positioning module are of a separable and detachable structure, the structure is simple, maintenance and replacement are convenient, and the exhaust gas treatment efficiency is greatly improved; and the device can be conveniently and rapidly positioned on an automobile chassis through the positioning module, the assembly and disassembly time of the device is shortened, and manpower and material resources are saved.

Description

technical field [0001] The invention relates to the technical field of automobile manufacturing, in particular to a novel automobile exhaust treatment device. Background technique [0002] At present, the existing automobile exhaust treatment devices have problems such as insignificant energy-saving effect, incomplete exhaust purification, and short service life. The emission of harmful gases and particulate matter in the exhaust gas. The main emissions of diesel engines are nitrogen oxides and particles. The commonly used post-treatment technologies include selective catalytic reduction and particulate filter. Both technologies require an exhaust processor to treat the exhaust gas. The exhaust processor has the function of noise reduction and emission reduction at the same time. Compared with the traditional silencer, it is large in size, heavy in weight, and high in cost. It needs a special bracket to install it. The space is also relatively large. However, the layout sp...

AI Technical Summary

Problems solved by technology

The left side and the front of the assembly frame of the frame-type automobile exhaust processor are designed with a mounting mechanism with long strip mounting holes, thereby reducing assembly difficulties caused by manufacturing errors, greatly reducing assembly time, and saving Separate brackets, bandages and other parts are removed; in addition, the assembly frame is also provided with a left side auxiliary installation mechanism, which improves the connection strength and connection reliability between the processor and the frame, but it is not efficient for exhaust gas treatment and has no Two exhaust gas treatment bodies are used at the same time, and the positioning method is relatively complicated, which is not convenient for maintenance and disassembly.

[0004] The application number is CN201521080736.0 utility model described in the automobile exhaust treatment device, although it can reduce the ternary harmful components in the automobile exhaust emission by more than 50%, and the energy saving is more than 20%, but it can not treat a large amount of exhaust gas at the same time. The exhaust emission efficiency after treatment is low, the whole device is not easy to disassemble, the service life is low, and the manufacturing process is complicated
