Durable automobile tail gas purifier

Abstract

The invention provides a durable automobile tail gas purifier. The durable automobile tail gas purifier comprises a shell, wherein a bent and spiral filter channel is arranged in the shell; the filter channel comprises a primary filter area located at an upper part and a secondary filter area located at a lower part; the primary filter area is filled with activated carbon; the secondary filter area is filled with a molecular sieve catalyst; an air guide plate is arranged between the primary filter area and the secondary filter area; the outer surface of the shell is coated with a rubber asphalt coating layer; and the inner wall of the shell is coated with an anti-oxidation coating layer. The durable automobile tail gas purifier provided by the invention has good anti-impact and anti-oxidation performance, and a long service life; and an automobile tail gas is sequentially filtered by the primary filter area and the secondary filter area through the bent and spiral filter channel, and a good purification effect is achieved. A gas in the primary filter area can be greatly guided into the secondary filter area through a guide action of the air guide plate, a turbulent flow is avoided, smooth passing of a gas flow is ensured, the contents of harmful substances in the automobile tail gas can be greatly reduced, and pollution to air is avoided.

Description

technical field [0001] The invention belongs to the technical field of automobile exhaust purification treatment, in particular to a durable automobile exhaust purifier. Background technique [0002] In today's modern civilization, cars have become an indispensable means of transportation for human beings. Cars bring great convenience to people's life and work.

Vehicle exhaust is one of the major contributors to air pollution. Especially harmful to the urban environment, causing respiratory diseases, causing high levels of surface air exhaust gas, and aggravating the urban heat island effect. The term is the main component of smog. The major offender in the smog is the exhaust emitted by vehicles using various fuels. Vehicle exhaust mainly includes incompletely burned fuel, ca...

AI Technical Summary

Problems solved by technology

Existing automobile exhaust purification devices have poor purification effect and short service life. During use, they are easily corroded by high-temperature exhaust gas and then oxidized, or are hit and damaged by small stones during driving. If the exhaust purification device is often replaced , which increases the economic burden on car owners
