Gliding-arc plasma organism treating device in combination with catalysts

Abstract

The invention relates to pollutant treating devices in the environmental technology, and discloses a novel gliding-arc plasma organism treating device in combination with catalysts. The gliding-arc plasma organism treating device is composed of a positive electrode, a negative electrode and a cylindrical sealing cavity, and the sealing cavity is composed of an upper insulation cover and a lower insulation cavity; the positive electrode comprises a central rotating shaft, at least three first protrusions in the same shapes radially extend out from the bottom end of the rotating shaft, and the top end of the rotating shaft penetrates through the insulation cover and is connected with an external high-voltage power source; the negative electrode is in a circular ring shape, is attached to theinner wall of the insulating cavity and is connected with the external high voltage power source, and second protrusions corresponding to the first protrusions of the positive electrode in position are arranged on the inner wall of the negative electrode; the sealing cavity is filled with the catalysts. The device is easy to operate and low in manufacturing cost; the length of electric arcs is developed by rotating the electrodes, and an unbalanced area is lengthened for sufficient reacting; meanwhile, due to the special arrangement mode of the electrodes, the catalysts can be in sufficient contact with the electric arcs, and the catalytic effect is maximized.

Description

technical field [0001] The invention belongs to the field of sliding arc plasma, and in particular relates to a sliding arc plasma organic matter processing device combined with a catalyst, which can be used for reactions such as organic matter cracking, reforming, and synthesis gas. Background technique [0002] Gliding arc discharge (GAD) plasma is a non-equilibrium plasma that can generate periodic swings under normal pressure, which was proposed by Czernichowski et al. in France in 1988. The original sliding arc reactor is mainly composed of two bifurcated blade electrodes. The nozzles are arranged at the top of the throat of the two electrodes. The high voltage is respectively connected to the two electrodes to break down and form an arc. Variety. [0003] Due to its unique advantages in stimulating chemical reactions, sliding arc discharge has become a research hotspot immediately after it was proposed. In the early 1990s, the sliding arc was successfully applied to ...

AI Technical Summary

Problems solved by technology

[0004] However, the traditional blade sliding arc and derivative reactors have the problem of short residence time of the fluid in the plasma reaction zone, and in order to ensure better arc extension, there are relatively strict requirements on the reaction gas flow rate
