Purification device for automobile tail gas

Abstract

The invention provides a purification device for automobile tail gas. The purification device comprises an engine exhaust pipe, an engine air inlet pipe, exhaust particle conveying pipes, a particle separator, a superfine particle filter, a three-way catalytic purifier, a temperature reductioner, a smoke eliminator, a gas purification box and a purified gas exhaust pipe, wherein the engine exhaust pipe is connected with the particle separator; the particle separator is connected with the superfine particle filter; the particle separator and the superfine particle filter are connected with the engine air inlet pipe through the exhaust particle conveying pipes; the superfine particle filter is connected with the three-way catalytic purifier; the three-way catalytic purifier is connected with the gas purification box; and the gas purification box is connected with the purified gas exhaust pipe. According to the purification device, the structure is reasonable, the cost is relatively low, and the purification effect is remarkable.

Description

technical field [0001] The invention relates to the field of automobile parts, in particular to an automobile exhaust purification device. Background technique [0002] In modern society, air pollution is becoming more and more serious, and smog weather appears, which has many adverse effects on people's life, travel, and health. Among them, automobile exhaust is one of the main sources of air pollution. With the rapid increase of automobile production and sales, the exhaust pollution of some automobiles whose exhaust exceeds the standard is particularly serious. Automobile exhaust exceeds the standard and is unqualified because the fuel in the engine cannot be completely burned, resulting in carbon deposition and accumulation, and more and more toxic substances; if such toxic air is directly removed, it will seriously pollute the atmospheric environment. Generally, people usually use two methods of engine internal control and engine external purification to purify automobi...

AI Technical Summary

Problems solved by technology

Automobile exhaust exceeds the standard and is unqualified because the fuel in the engine cannot be completely burned, resulting in carbon deposits and accumulation, and more and more toxic substances; if such toxic air is directly excluded, it will seriously pollute the atmospheric environment

Generally, people usually use two methods of engine internal control and engine external purification to purify automobile exhaust. Engine internal control is to reduce automobile emission pollutants by controlling the working process of the engine itself. Many measures have been taken for the engine, which have a certain effect on reducing vehicle emissions, but the control effect is still not ideal
