Plasma air disinfection and purification device

Abstract

A plasma air disinfection and purification device comprises a shell in which a plasma generation cavity is formed, a plasma generating device is arranged in the plasma generation cavity and comprises a plurality of electrode plates which are arranged at intervals in an up-and-down mode and horizontally arranged from an air inlet to an air outlet, insulating supports are arranged at the air outlet ends and the air inlet ends of the electrode plates, at least one electrode band is arranged between every two adjacent electrode plates, the two ends of each electrode band are installed on the insulating supports, edge teeth extending to the two outer sides of each electrode band are arranged on the two lateral sides of the electrode band, when a power source is switched on, horn-shaped glow discharge is generated between each edge tooth of each electrode band and the upper electrode plates as well as between each edge tooth of each electrode band and the lower electrode plates, discharge areas coincide in a crossed mode, and high-density plasma is generated. According to the device, due to the arrangement of the electrode bands, the wire breakage problem of wire electrodes is solved, and service life is longer; the edge teeth are arranged, horn-shaped glow discharge is generated, and the disinfection effect is stronger.

Description

technical field [0001] The invention relates to an air disinfection and purification device, in particular to a plasma air disinfection and purification device. Background technique [0002] At present, the widely used air disinfection method adopts ozone disinfection or ultraviolet disinfection method, and the plasma air disinfection method is gradually used. [0003] The ozone disinfection method is to convert oxygen ions (0 2- ) ionized into reactive oxygen species (O 3 ), an oxygen generator or an oxygen tube is required, and the ozone must reach a certain concentration in order to play a role in sterilization. Ozone concentration in the air reaches 0.01-0.02mg / m 3 Odor can be smelled from time to time, and the ozone concentration in the air reaches 0.1mg / m 3 When it is used, it will irritate the eyes, nose, throat and respiratory tract of people, and has a toxic effect on the human body. It cannot be used when there are people. People can only enter the room aft...

AI Technical Summary

Problems solved by technology

The use effect of ultraviolet lamps is inversely proportional to the time and radiation intensity. Generally, the lamp tube needs to be replaced when the service life does not exceed 1000 hours. The loss is relatively large, and ultraviolet radiation is harmful to human skin and eyes, so it cannot be used in the presence of people.

[0005] Compared with the traditional ozone air disinfection and ultraviolet air disinfection, the plasma air disinfection method has the characteristics of fast sterilization speed, no secondary pollution, low energy consumption, etc., can dec
