A multi-source oblique insertion plasma gas processing device

Abstract

The present invention discloses a multi-source obliquely-inserting type plasma gas treatment apparatus, which comprises a gas inlet channel, a deceleration chamber, a gas treatment zone, a gas discharging absorption device and plasma sources, wherein the upper end of the gas treatment zone is sequentially connected to the deceleration chamber and the gas inlet channel, the lower end of the gas treatment zone is connected to the gas discharging absorption device, the gas treatment zone comprises a plurality of gas treatment chambers connected in a layered manner, plural rows of plasma source inserting ports communicated to the gas treatment chamber are arranged along the circumferential directions of each gas treatment chamber, the plasma source inserting ports are respectively provided with the plasma sources, and the included angle formed between the axial line of the plasma source and the center axis of the gas treatment chamber is an acute angle. According to the present invention, in the case of the large flow rate gas inlet, the plurality of the plasma sources simultaneously work, and each plasma can be fully contact the gas to be treated, such that the gas treatment effect and the gas treatment efficiency of the plasma are substantially improved; and the multi-source obliquely-inserting type plasma gas treatment apparatus has advantages of simple structure, high spatial utilization rate, easy maintenance, and easy repair.

Description

technical field [0001] The invention belongs to the technical field of gas treatment and air purification, and in particular relates to a multi-source obliquely inserted plasma gas treatment device. Background technique [0002] With the rapid development of my country's industry, the level of air pollution across the country is becoming increasingly severe, and most areas often experience large-scale smog. At present, the main air purification methods and technologies mainly include liquid absorption method, adsorption method, thermal oxidation, biological treatment method, condensation method and plasma technology. Among them, the principle of plasma technology to achieve air purification is as follows: [0003] (1) Through collisions, high-energy electrons transfer energy to other particles, and other particles that obtain energy are excited, and some particles are also ionized into active groups; [0004] (2) The active group transitions from the high-energy excited sta...
