Motor engine exhaust gas cleaning device

Abstract

The invention discloses an exhaust decontamination device for locomotive engines, belonging to the technology field of the locomotive engines in internal-combustion engines, which comprises an outer casing, an air inlet pipe and an escape pipe, wherein the outer casing which is metallic casing is made of a photo, heating catalytic decontamination reactor outer casing which is provided with a photo, heating catalytic decontamination reactor and a collector horizontal pulse electrostatic decontamination reactor outer casing which is provided with a collector horizontal pulse electrostatic decontamination reactor, the photo, heating catalyst body of the photo, heating catalytic decontamination reactor is titanium, the collector horizontal pulse electrostatic decontamination reactor is made of a corona wire, an electrode tube, a porcelain supporting plate of the electrode tube, a supporting plate and a connecting screw rod, wherein the corona wire is crossed along the axial cord of the electrode tube. The exhaust decontamination device enables the automobile end gas exhaust volume to achieve phase normalized value of GB18352.3-2005 <exhaust limiting volume and measuring method of light-duty cars contaminants> IV.

Description

technical field [0001] The invention relates to a motor vehicle engine in an internal combustion engine, and more particularly relates to a motor vehicle engine exhaust purification device. Background technique [0002] In recent years, scientific research has found that when the motor vehicle engine is working, the exhaust gas contains hundreds of components, including carbon monoxide CO, hydrocarbon HC, nitrogen oxides NO X , sulfur dioxide SO 2 , lead compounds and various solid particles such as PM, which seriously pollute the environment and endanger human health. There are mainly two ways to purify motor vehicle engine exhaust: internal purification and external purification. Internal purification is achieved by improving the structural design of the motor vehicle engine, controlling the combustion process, or using clean fuel; external purification is achieved by adding a purification device to the exhaust pipe of the motor vehicle engine. At present, the external ...

Problems solved by technology

Although the three-way catalytic converter has a certain effect of reducing harmful components in the exhaust gas, it also has some inherent weaknesses, such as, it does not purify at low temperatures, has new heavy metal pollution, and after a period of use, the effect decreases, and In case of leaded fuel, it will be poisoned and invalidated, etc.

With the development of science and technology and the improvement of people's environmental and health awareness, people have higher and higher requirements for exhaust purification of motor vehicle engines, and the existing external purification devices are difficult to meet people's needs. Therefore, it is necessary to explore new Motor vehicle engine exhaust purification device
