Photoelectrocatalysis radio frequency heating sterilization sterilizer

Abstract

The invention discloses a photoelectrocatalysis radio frequency heating sterilization sterilizer, which comprises a shell, and an air inlet and an air outlet which are communicated through an air channel are formed in the shell; an exhaust fan is arranged in the exhaust port; a photoelectric catalyst net is provided with a positive electrode and a negative electrode which are arranged in the air passage at an interval along the extending direction of the air passage; a light source is arranged in an air channel between the two photoelectric catalyst nets; an electrode, wherein the positive electrode and the negative electrode of the electrode are electrically connected with the two photoelectric catalyst nets respectively; and a radio frequency generator is arranged in the air channel between the exhaust fan and the photoelectric catalyst net. A series of high-reaction-activity free radicals, superoxide free radicals and the like are generated on the surface of the photoelectric catalyst net by utilizing light emitted by a light source to irradiate the photoelectric catalyst net, exciting by a direct-current electrode and the like, and the free radicals and bacterial viruses in the air are quickly subjected to free radical degradation reaction to generate non-toxic components, and even are mineralized to generate carbon dioxide and water; Therefore, bacteria, viruses and pathogenic microorganisms in the air are thoroughly and permanently killed.

Description

technical field [0001] The invention relates to the technical field of air purification, in particular to a photoelectrocatalytic radio frequency heating disinfection sterilizer. Background technique [0002] Viruses and bacteria can attach to air pollutants, droplets and smog to pollute the air, causing human-to-human transmission. At present, the air technologies for dealing with such bacteria and viruses mainly include: chlorine-containing disinfectant killing method, ultraviolet lamp sterilization and detoxification method, high-voltage electrostatic method, ozone method, mask adsorption isolation method, plasma method, etc. Obviously, the disinfection effect of chlorine-containing disinfectant and ozone method is remarkable, but it brings secondary pollution, and it is also harmful to human health. It can also be resurrected, and the high-voltage electrostatic method also has similar problems. [0003] For this reason, the present invention can directly degrade and br...
