Description

Technical Field

[0001] The utility model relates to the technical field of automobile manufacturing, in particular to an automobile exhaust filter. Background Art

[0002] As people's living standards improve, there are more and more cars, and the exhaust gas emitted by cars causes more and more pollution to the environment. At present, the air quality of about 2 / 3 of cities in my country does not meet the national standards. Among them, the pollution contribution rate of motor vehicles in large cities has exceeded 50%. In some coastal cities, the pollutants emitted by mobile pollution sources such as cars and motorcycles account for a higher proportion of the total amount of local urban air pollutants. The pollution of the atmospheric environment by automobile exhaust is becoming more and more serious, seriously endangering the health of residents. This has attracted great attention from many countries, especially developed countries with a large number of cars. It can be seen that paying attention to emission pollution control, improving air quality, and automobile exhaust pollution control methods have become a common concern in modern society. In the prior art, automobile exhaust directly passes through the exhaust pipe to The main pollutants of automobile exhaust discharged into the atmosphere include solid suspended particles, carbon monoxide, carbon dioxide, hydrocarbons, nitrogen oxides, lead and sulfur oxides, metal dust, strong carcinogen benzopyrene and pathogenic microorganisms. Solid suspended particles enter the human lungs through breathing, and are retained in different parts of the respiratory tract by collision, diffusion, deposition, etc., causing respiratory diseases. When the suspended particles accumulate to a critical concentration, they will stimulate the formation of malignant tumors. In addition, suspended particles can directly contact the skin and eyes, block the hair follicles and sweat glands of the skin, cause dermatitis and conjunctivitis, and even cause corneal damage, which is very harmful to the human body. Moreover, a large part of the carbon dioxide that produces the "greenhouse effect" comes from the carbon dioxide in automobile exhaust, which has a certain impact on the environment.
