Problems solved by technology

However, the catalytic converter will generate a lot of heat when it is working. The higher the heat, the higher the oxidation temperature. When the temperature exceeds 850-1000 ° C, the catalyst in the inner coating is likely to fall off and the carrier is broken.

Abstract

The invention relates to an automobile tail gas treatment device, and discloses an automobile exhaust pipe with a tail gas treatment function. The automobile exhaust pipe comprises a catalytic converter, a first silencer and a second silencer which are sequentially connected through a pipeline; an air inlet pipeline of the catalytic converter is connected with a particle processor, and the particle processor comprises a cylindrical body; and the cylindrical body is internally provided with an inner chamber and an outer chamber, the outer chamber is internally provided with a cooling water pipe, and the inner chamber is internally provided with a heating coil. According to the automobile exhaust pipe with the tail gas treatment function, particulate matters included in tail gas entering thecatalytic converter are few, the whole pretreatment of the automobile tail gas is achieved, it is ensured that subsequent tail gas in the catalytic converter is treated more efficiently, thus the purifying degree of the finally-exhausted automobile tail gas is greatly improved, the damage of the automobile tail gas to a human body is reduced, and the atmosphere environment is effectively protected.

Description

technical field [0001] The invention relates to an automobile tail gas treatment device, in particular to an automobile exhaust pipe. Background technique [0002] With the improvement of the quality of life, automobiles have become a necessary means of transportation for people. Although they bring convenience to our lives, the exhaust gas emitted by them has caused great pollution to the atmosphere. Car exhaust contains carbon monoxide, nitrogen oxides, and other solid particles that have adverse effects on the human body. [0003] Among them, the composition of solid suspended particles is very complex and has strong adsorption capacity. It can adsorb various metal dusts, strong carcinogens, benzopyrene, and pathogenic microorganisms. and other ways to stay in different parts of the respiratory tract, causing respiratory diseases. And when the suspended particles accumulate to a critical concentration, they will stimulate the formation of malignant tumors. In addition,...
