Automobile three-way catalyst convenient to clean

Abstract

The invention discloses an automobile three-way catalyst convenient to clean. The automobile three-way catalyst convenient to clean is characterized by comprising a front connecting flange, an air inlet pipe, a barrel body and an air exhausting pipe, wherein a catalyzer module and a liner are arranged in the barrel body; the catalyzer module is provided with three layers including a first layer of catalyzer module, a second layer of catalyzer module and a third layer of catalyzer module which are sequentially communicated; the end of the air inlet pipe is connected with the first layer of catalyzer module; the third layer of catalyzer module is connected with the end of the air exhausting pipe. The automobile three-way catalyst convenient to clean has the beneficial effects that due to the design of the three layers of the catalyzer module, impurities with larger particles are basically stayed in the first layer of catalyzer module, and the first layer of catalyzer module needs to be cleaned seriously during detachment and cleaning; if the first layer of catalyzer module is blocked or oxidized seriously, the first layer of catalyzer module can be replaced independently. Meanwhile, the time of waste gas staying in the catalyzers is prolonged, the catalyzing effect is improved, and the catalyzing efficiency can be greatly improved.

Description

technical field [0001] The invention relates to an automobile three-way catalytic converter which is easy to clean, and belongs to the technical field of automobile machinery. Background technique [0002] The three-way catalytic converter of an automobile is an important part to improve automobile emission and reduce automobile exhaust pollution. However, as the use time increases, carbon deposits, sulfur-containing, and phosphorus-containing compounds in automobile exhaust will deposit on the surface of the catalyst on the carrier of the three-way catalytic converter, causing catalyst poisoning and a decrease in catalytic efficiency, greatly reducing the catalytic efficiency of the three-way catalytic converter. The effect on the purification of automobile exhaust. [0003] At present, the problem encountered by most three-way catalytic converters is that with the increase of the use time, the oxidation effect will become worse and worse. Although regular cleaning is nece...
