Abstract

The invention discloses a discharge electrode structure of a plasma air purification device. The electrode structure comprises a positive electrode group and a negative electrode group, wherein at least one of the positive electrode group and the negative electrode group is wrapped with insulating medium; and the two electrode groups contact directly, such that a contact point is formed. According to the invention, the discharge electrode structure is applied to the plasma air purification device, so a great amount of low temperature plasma is generated at an electrode intersection and a nearby area of the electrode intersection through the structure; the low temperature plasma has properties of glow-like plasma, wide sterilization range, high sterilization rate, short time consumption and low power consumption; in addition, the adopted net-like structure can not only ensure good air permeability but also enlarge the actual plasma function area, therefore, the sterilization rate is further improved.

Description

technical field [0001] The invention belongs to the technical field of air disinfection and purification. Specifically, the invention relates to a discharge electrode structure of a plasma air purification device. Background technique [0002] Social development and the continuous expansion of industrial scale have largely destroyed the natural environment, and gas pollution is one of the important contents. Not only that, but in today's environment, many special viruses like SARS and H1N1 have emerged, which seriously threaten the survival of human beings. With the development of the economy and the continuous improvement of people's living standards, the demand for hygiene fields such as air purification and disinfection has become increasingly strong. [0003] Now, the application of plasma technology is more and more widely, especially in the field of sterilization, it has been proved to have a good application effect. Plasma sterilization has a high success rate and s...
