Single-tube ultra-high-power ultraviolet surface disinfection technology based on microwave source

Abstract

The invention discloses a single-lamp-tube ultra-high-power ultraviolet surface disinfection technology based on a microwave source. The technology comprises the following steps of conveying, high-power pulse microwaves, ultraviolet disinfection and ozone treatment. Oxygen in air is ionized through 185 nm ultraviolet rays excited by microwaves, then ozone is produced, the strong oxidation effect of the ozone is utilized, the ozone has the decomposition effect on various organic matter from hydrocarbon to carboxylic acid, the bacterium killing effect can be effectively achieved, the organic matter can be degraded into harmless gas, and air pollution is avoided; moreover, the microwave simulation and test system based on the bionic principle can improve the utilization rate of acting microwaves, reduce the energy loss outside the range of inactivating germs, ensure the effectiveness of sterilization, and save the resource cost. Moreover, high-power microwaves, ultraviolet disinfection and ozone are matched for use, so that rapid dead-corner-free internal and external integrated disinfection can be realized, and economic loss caused by germs carried by imported goods can be effectively prevented.

Description

technical field

[0001] The invention belongs to the field of microwave ultraviolet disinfection and sterilization equipment, and more particularly relates to a single lamp ultra-high power ultraviolet surface disinfection technology based on a microwave source. Background technique

[0002] The microwave ultraviolet disinfection and sterilization equipment is a high-efficiency disinfecting tool suitable for frequent switching in public places. Its working principle is that the ultraviolet lamp (UV-C253.7nm) is combined with a high-sensitivity microwave sensor; when a person enters the sensing range of the microwave sensor , the microwave sensor will immediately disconnect the circuit connection of the ultraviolet lamp, and the ultraviolet lamp will be turned off to prevent ultraviolet rays from causing damage to the human body;

[0003] In addition, due to the thermal effect of the existing sterilization equipment, when microwave sterilization of cold chain food is performed,...
