Embodiment Construction

[0008] 1. The electric field dust collection part of the automobile exhaust particle electrostatic removal system is composed of a silicon rectifier transformer, a tubular thorn cathode wire, a metal anode particle collecting plate and an outer insulator. The silicon rectifier converts the low voltage transmitted by the automobile generator into 15 ~20kv high voltage to generate corona on the cathode line. After the exhaust particles are charged in the electric field, they move to the anode under the action of the electric field and are captured. Due to the high voltage electric field, the outside of the device needs to be wrapped and sealed with insulating materials. To prevent leakage.

[0009] 2. The flue gas buffer part of the electrostatic removal system for automobile exhaust particles is composed of an oval buffer tank, which is made of metal. The air inlet is connected to the exhaust pipe, and the air outlet is connected to the dust collection part of the electric field...

Abstract

The invention discloses a technique method used for removing automobile tail gas particles. According to the method, the electrostatic precipitation technology serves as the main technique means, the method can be used for removing tiny particles existing in automobile tail gas, and a very good removing effect can be achieved particularly for PM2.5 type particles. Due to the fact that compared with other particle capturing technologies, an adsorbent or a catalyst is not needed in the electrostatic precipitation technology, the adaptability to the smoke components is high, and no special requirement for the sulphur content of fuel does not exist; and meanwhile the problem of increasing of exhaust resistance due to blockage of the adsorbent caused by accumulation of the particles is avoided. System running is relatively stable. The technique method has the beneficial effects of being efficient in running, low in manufacturing cost, high in adaptability and the like, the problems of a current tail gas particle purifying system in the actual using process can be reduced or eliminated, the actual application threshold is lowered, and the technique method can serve as a main technique means for commercial application and popularization.

Description

technical field [0001] The invention belongs to the field of automobile exhaust emission pollution control and air pollution treatment, and its technical content relates to a comprehensive solution method for removing particle pollutants in automobile exhaust. Background technique [0002] In recent years, smog has repeatedly appeared in major cities in my country, and the culprit of this problem is the particulate matter (PM) in the air. Generally speaking, particulate pollutants can be divided into different grade types such as PM10, PM2.5, PM1, and PM0.5 according to their diameters. Among them, PM2.5 inhalable particulate matter is the main particulate pollutant that causes atmospheric smog and respiratory diseases due to its large number. Among the many emission sources of atmospheric particulate pollutants, automobile exhaust emission is one of the most important emission sources. Pollution problems are also getting worse. Studies have shown that automobile exhaust ...
