The application has the implementation principle that disinfectant with preset concentration is supplied to the releasing device 11, and pure chlorine dioxide gas is released in an aeration mode through the releasing device 11; meanwhile, the high-frequency ultrasonic atomizer 21 is used for vaporizing sodium chloride pure water, sodium chloride particles with the particle size of 1-5 microns are released through the gas-liquid separation device 22, the gaseous sodium chloride particles with the particle size of 1-5 microns are dried at high temperature through the dryer 23, the submicron sodium chloride particles and chlorine dioxide gas molecules are released to be mixed to form aerosol, the aerosol is continuously conveyed to an air inlet pipe inlet of an air conveying device 6 such as a central air-conditioning system or a fresh air system and the like, the aerosol enters an air supply pipeline 14 of the air conveying device 6 such as the central air-conditioning system or a fresh air system and the like along with fresh air, the aerosol is conveyed to a far-end place while the fresh air and air supply pipeline 14 is sterilized, the aerosol is released into a space, and air and objects in the space are sterilized in an all-dimensional and dead angle-free mode.

The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
