Abstract

The invention relates to a discharge plasma vehicle tail gas treatment apparatus with spiral electrode rotating, and a discharge plasma vehicle tail gas treatment method with spiral electrode rotating, and belongs to the technical field of vehicle tail gas treatment. A purpose of the present invention is to solve problems of non-uniform plasma generation and low purification efficiency of the existing low temperature plasma reactor for the vehicle tail gas treatment. The discharge plasma vehicle tail gas treatment apparatus comprises a motor, a tail gas plasma treatment tube, a spiral electrode and a copper tube, wherein the space between the spiral electrode and the tail gas plasma treatment tube is the vehicle tail gas channel and is the plasma reaction zone, one end of the spiral electrode is connected with the motor, and the other end is fixed at the head end of the horizontal tail gas treatment section. According to the method, the copper tube and the spiral electrode are connected to the power supply, and then the motor drives the spiral electrode to rotate, such that the treatment on the vehicle tail gas is achieved under the effect of the plasma in the horizontal tail gas treatment section. The apparatus and the method of the present invention are used for the vehicle tail gas treatment.

Description

technical field [0001] The invention relates to a discharge plasma automobile tail gas treatment device with a rotating spiral electrode and a treatment method thereof, belonging to the technical field of automobile tail gas treatment. Background technique [0002] As the most important means of modern transportation, the automobile makes people's life more convenient and faster, but it also brings many unavoidable problems. The CO and NO emitted by it x , HC, SO 2 , Pb and other pollutants are not only harmful to human health, but also the main components of acid rain and photochemical smog. Automobile exhaust pollution has attracted widespread attention around the world. According to the survey, more than 90% of CO, more than 60% of HC and more than 30% of NO in urban air x from vehicle emissions. It can be seen that the purification of pollutants in automobile exhaust is a top priority. [0003] In recent years, the rapidly developed low-temperature plasma technology...
