Gas discharge plasma generating device with high air volume

Abstract

The invention relates to the technical field of environmental pollution abatement, in particular to a gas discharge plasma generating device with a high air volume.The gas discharge plasma generating device comprises a frame, anode tubes, cathode tubes, two anode fixing frames, insulating columns and a high-voltage module.The frame comprises a base and a single side wall, the high-voltage module is inlaid in a surface of the side wall, the cathode tubes are mounted in the base of the frame, the two anode fixing frames are vertically mounted on the base of the frame, the ends of each anode fixing frame are mounted on the base of the frame via the corresponding insulating columns, the anode tubes are fixed onto clamp grooves of the anode fixing frames and are suspended on the cathode tubes, and the anode tubes and the cathode tubes are arranged at intervals in a mismatch manner.The gas discharge plasma generating device has the advantages that anodes and cathodes are separated from one another, accordingly, discharge optimization and safety can be guaranteed, problems of electric leakage and creepage due to the fact that existing anodes and existing cathodes are arranged in the same circular tube and are excessively close to one another can be solved, equipment can be protected, and purification functions can be enhanced.

Description

Technical field [0001] The invention relates to the technical field of environmental pollution control devices, in particular to a device for generating plasma by gas discharge with large air volume. Background technique [0002] With the development of China's economy and the improvement of technological level, a large amount of refractory organic industrial waste gas has been generated in printing and dyeing, pharmaceutical, chemical, petroleum and other industries, which not only caused serious direct environmental pollution, but also became secondary pollutants such as ozone and haze. It can be combined with other pollutants and dust particles in the air, which can cause a series of problems such as human health and peculiar smell disturbing people. Low-temperature plasma technology is used in exhaust gas purification, especially to eliminate large air volume pollution sources. It is widely used in the purification of various odors and VOCs pollutants. Dielectric barrier dis...

AI Technical Summary

Problems solved by technology

The plate type is difficult to apply industrially due to problems such as plate corrosion, uneven discharge, and marginal effects; the sleeve type has advantages in generating stable plasma, but it is limited by the plight of small ventilation, and it is difficult to use it under the condition of large ventilation. Use; although the calandria type can realize gas discharge under the condition of large ventilation to generate low-temperature plasma, it is difficult to lead out the positive and negative electrodes, prone to creepage and terminal shielding problems, making it difficult for the calandria reactor to be stable for a long time run

[0004] Therefore, need badly a kind of new gas discharge device, in order to overcome the drawback that above reactor produces plasma
