Epidemic cerebrospinal meningitis, mumps, viral pneumonia, influenza, acute pharyngitis, tuberculosis, scarlet fever, legionella disease, pertussis, diphtheria, smallpox are all also air-borne and air-borne. Therefore, the air disinfection is an important measure for preventing and controlling infectious diseases and preventing cross infection, is particularly important for the air preventive disinfection in places with relatively concentrated personnel, such as hospitals, libraries, supermarkets, schools, stations, canteens and other public environments with large spaces, can effectively disinfect air, can kill and activate pathogenic microorganisms adhered and dyed on suspended particles in the air within a certain time, can play a key blocking role in the processes of preventing diseases, controlling the propagation of virus air droplets and aerosol, and is similar to an intangible mask.
The traditional method for disinfecting the surface of the object mainly comprises the steps of spraying, fumigating and soaking the disinfectant. The method for sterilizing the air in the space comprises the steps of closed fumigation, ultraviolet sterilization, ozone sterilization, physical filtration and sterilization of the air and the like.
The spray disinfection method has the advantages that the accuracy of concentration proportion of disinfectant, the sprayed areas, parts, alcohol spraying amount and the final disinfection and sterilization effect are directly affected by human factors. Meanwhile, the personnel who spray the disinfectant need to be in the body to pollute the environment, and also bear high risk;
the fumigation mode generally needs higher disinfectant concentration, the space is closed for a long time, and the use of places is influenced for a long time;
ultraviolet disinfection, high-power ultraviolet rays have harm to organism functions. The ultraviolet ray is influenced by the emission power, so that the ultraviolet ray is limited to adapt to and meet the disinfection of a large amount of space, meanwhile, the size of the humidity of the space directly influences the disinfection effect, and in addition, the ultraviolet ray has the defect of blindness control on eyes and is not suitable for being started under the condition of people;
ozone disinfection, bad humanization of ozone smell is suitable, and ozone is unstable in the air simultaneously, and the retention time is shorter, is unsuitable for large space disinfection, directly influences the effect of disinfecting to the virus continuously.
In conclusion, the existing disinfection has the defects of low disinfection efficiency and poor humanization.
