[0031] As Figures 1 - 5 shown, the principle of the medical clean room gas purification and disinfection device provided in this embodiment is as follows: When the device is in use, the sealing door 24 should be opened first, the support card frame 5 should be installed on the first support plate 4, and then the active adsorption plate 6 selected according to the use environment should be loaded into the support card frame 5. Subsequently, the clamping frame 8 is installed on the inner walls on both sides of the ultraviolet disinfection chamber 7, and the ultraviolet disinfection lamp tube 9 is installed on the clamping frame 8.

[0032] When the device is running, the driving motor 15 drives the rotating fan blade 16 to rotate, sucking the air outside the device into the atomizing disinfection chamber 10 through the grid air inlet 28. The disinfection solution in the disinfection solution storage tank 18 will be sprayed out from the atomizing nozzle 20 and disinfect the air in the atomizing disinfection chamber 10. The disinfected air passes through the hollow partition board 23 and flows into the filtering chamber 2. The air entering the filtering chamber 2 passes through the active adsorption plate 6, and harmful substances in the air are removed through multiple filtration and adsorption. The filtered air enters the ultraviolet disinfection chamber 7 through the ventilation holes on the hollow partition board 23. The air entering the ultraviolet disinfection chamber 7 is subjected to the last step of drying and disinfection under the irradiation of the ultraviolet disinfection lamp tube 9. The disinfected air is transported outside the device through the grid air outlet 27;

[0033] When the device has been used for a long time, the air purification effect may not be ideal. At this time, the sealed door 24 can be opened, and the harmful substances inside the facility can be wiped and cleaned. At the same time, the saturated activated adsorption plate 6 is taken out from the filter chamber 2. Subsequently, a new or desorbed activated adsorption plate is reinstalled, and it is checked whether the ultraviolet disinfection lamps 9 on both sides of the inner wall of the ultraviolet disinfection chamber 7 are working properly. If a fault occurs, the ultraviolet disinfection lamp 9 needs to be replaced. Then, it is checked whether the disinfection solution in the disinfection solution storage tank 18 is sufficient. If it is insufficient, the disinfection solution storage tank 18 needs to be added with the disinfection solution. After the above work is completed, the sealed door 24 can be closed, and the device can be placed in the required environment for use.
