Parallel medium blocking discharge reactor

Abstract

The invention provides a parallel medium blocking discharge reactor which comprises a cylindrical discharge unit supporting frame and a discharging module in the cylindrical discharge unit supporting frame. The discharge module is obtained through parallelly connecting a plurality of medium blocking discharging units. Each medium blocking discharging unit comprises a high-voltage electrode, a low-voltage electrode, blocking medium and high-voltage electrode fixing brackets. The blocking medium has a cylindrical structure. The low-voltage electrode sleeves the outer circumference of the blocking medium. The two high-voltage electrode fixing brackets are fixed to two ends of the blocking medium. The centers of the two high-voltage electrode fixing brackets are connected with two ends of the high-voltage electrode. The parallel medium blocking discharge reactor is advantageous in that a multi-tube parallel medium blocking discharge low-temperature plasma reactor is presented through combining multiple subject theories such as gas discharge and low-temperature plasma physical chemistry, effectively reducing particle discharge of a diesel engine, realizing high efficiency which can reach 50-90%, and furthermore preventing air discharge back pressure increase caused by carrier filling or particle trapping.

Description

technical field [0001] The invention belongs to the technical field of particle pollutant control, in particular to a parallel dielectric barrier discharge reactor. Background technique [0002] PM (Particulate Matter) in the air has attracted much attention because of its carcinogenicity, which brings great harm to the environment and human health. At present, the main sources of particulate matter pollution in my country are mainly coal combustion and motor vehicles. Due to the increasingly stringent emission regulations, it is difficult for simple combustion control technology to meet the requirements of the regulations. Therefore, the post-treatment technology of combustion sources needs to be solved urgently. [0003] Low-temperature plasma used in particle control technology originated from electrostatic precipitator technology, and is often used in coal-fueled factories, power stations, and metallurgical places. Low-temperature plasma is mainly generated by corona dis...

Problems solved by technology

[0004] However, there is still a long way to go to apply low-temperature plasma technology to diesel engine exhaust aftertreatment. Most of the research is in the laboratory stage, and there are still many problems to be solved in terms of reactor structure design, power supply operating conditions, energy consumption, and physical and chemical reactions. problem
