Purification treatment device for automobile exhaust

Abstract

The invention relates to the technical field of automobile exhaust treatment, and discloses a purification treatment device for automobile exhaust. The purification treatment device comprises a shell,a shock pad is fixedly connected to the middle of an inner cavity of the shell, a three-way catalytic layer is fixedly connected in the shock pad in a sleeved manner, and a hot air turning ball is movably connected to the position, located on the right side of the three-way catalytic layer, of the inner cavity of the shell in a sleeved manner. According to the purification treatment device for the automobile exhaust, through cooperation of a pushing device, a turning device and a deposited carbon removing device, when the exhaust is exhausted from a gas inlet hole in the right side of the shell, the pressure intensity of the left side of the deposited carbon removing device is smaller than that of the right side of the deposited carbon removing device at the moment, for the exhaust, an upper scraping hemisphere, a lower scraping hemisphere, a strip-shaped scraping piece fixedly installed in a transverse ventilation groove and a carbon collecting bag can conveniently scrape deposited carbon adhering to the lower scraping hemisphere and the upper scraping hemisphere, a limiting pipe rotates around a360-degree curved rail clamping strip on a linkage column, the deposited carbon is effectively removed, meanwhile, catalytic activity of the three-way catalytic layer is maintained, and the environment is protected.

Description

Technical field [0001] The present invention relates to the technical field of automotive exhaust gas treatment, in particular a purification treatment device for automobile exhaust gas. Background technique [0002] Car exhaust is the exhaust gas generated during use, containing hundreds of different compounds, wherein the contaminants are solid suspension fine particles, carbon monoxide, carbon dioxide, hydrocarbons, nitrogen oxide, lead and sulfur oxygen, etc., exhaust gas is directly harmful While human health, it will also have a profound impact on the environment of human life. Car exhaust gas purification treatment can effectively reduce exhaust gas emissions and nitrogen oxides, carbon oxides emissions, and the environmental protection is critical. [0003] The existing automotive exhaust cartridge uses a three-dimensional catalytic converter to reduce hydrocarbon in the exhaust, and can also reduce the nitrogen oxide in the exhaust into harmless nitrogen and oxygen, but ...
