Device and method for generating dielectric barrier discharge plasma

Abstract

The invention relates to a dielectric barrier discharge plasma generation device and a dielectric barrier discharge plasma generation method. The dielectric barrier discharge plasma generation device comprises porous conductive metal plates, a fixing disk frame and an electrode conductive fixing frame, wherein the fixing disk frame and the electrode conductive fixing frame are connected with the porous conductive metal plates. A plurality of round inorganic material pipes are arranged inside the porous conductive metal plates in a sleeved manner, a conductive film is arranged on the inner wall of each round inorganic material pipe, the electrode conductive fixing frame is arranged at the tops of the round inorganic material pipes, an electrical lead is connected outside each round inorganic material pipe, and insulation columns are arranged at two ends of the round inorganic material pipes symmetrically and are connected with the round inorganic material pipes through the electrical leads. The dielectric barrier discharge plasma generation device and the dielectric barrier discharge plasma generation method have the advantages that multiple groups of coaxial cylindrical type discharge tubes are combined together in a rectangular manner to form an integrated discharge reaction device compact in structure; the device is convenient to mount, small in occupied space and convenient for uniform air flow distribution; multi-layer porous conductive metal plates can be arranged vertically to achieve multi-stage degradation reaction, so that pollutant purifying efficiency is improved.

Description

technical field [0001] The invention relates to a plasma generating device, in particular to a dielectric barrier discharge plasma generating device and method, and belongs to the technical field of environmental pollution control. Background technique [0002] Air pollution is a serious challenge facing the world today. With the development of the world economy and technological level, printing and dyeing, pharmaceutical, chemical, petroleum and other industries have produced a large amount of refractory organic industrial waste gas, which not only caused serious direct environmental pollution, but also became an important source of secondary pollutants such as ozone and smog. It can be combined with other pollutants and dust particles in the air, which will cause a series of problems such as human health and odor nuisance. The search for efficient, economical and environmentally friendly new treatment methods for refractory organic industrial waste gas has been It is an i...
