A kind of air sterilization and purification device and its application

Abstract

The present invention provides an air sterilization and purification device and an application thereof. The air sterilization and purification device includes a first sterilization and purification unit, a second sterilization and purification unit and a third sterilization and purification unit. The purification unit is connected to the third sterilization and purification unit; the first sterilization and purification unit and the third sterilization and purification unit both carry out sterilization with different effects in the exhaust system and the return air system by changing the wavelength of short-wave ultraviolet rays; the second sterilization and purification unit passes By destroying chromosomes for sterilization, the invention solves the problem of cross-infection caused by the air ducts connecting the rooms in various areas after the polluted air in the building is mixed with each other through the air-conditioning ventilation system, and at the same time, it can also solve the problem of cross-infection. The polluted air is concentrated and discharged to the outdoors through the exhaust ducts of the ventilation system, causing the pollution of the air environment around the building.

Description

【Technical field】 [0001] The invention relates to the technical field of sterilizing air conditioners, in particular to an air sterilizing and purifying device and its application. 【Background technique】 [0002] The transmission route of respiratory infectious diseases is mainly through droplets, and can also be transmitted through direct close contact or indirect contact, but there are still many unknown details. [0003] At present, due to the impact of the novel coronavirus pneumonia epidemic, many public buildings with centralized air-conditioning units have taken measures to temporarily suspend the use of air-conditioning units. , It is likely to spread through the supply and exhaust ducts connecting the rooms in each area, resulting in cross-infection.

AI Technical Summary

Problems solved by technology

[0003] At present, due to the impact of the novel coronavirus pneumonia epidemic, many public buildings with centralized air-conditioning units have taken measures to temporarily suspend the use of air-conditioning units. , it is likely to spread through the supply and exhaust ducts connecting the rooms in each area, resulting in cross-infection

In addition, in special buildings such as hospitals, in order to prevent the spread of polluted air through air-conditioning and ventilation devices, each functional area has corresponding setting requirements and operating regulations, but if preventive measures to prevent cross-infection are not taken, there is still no fundamental Prevention of nosocomial infection, as well as the accumulation of polluted air caused by centralized exhaust to the outside, resulting in pollution of the surrounding air environment

[0004] At present, air-conditioning and ventilation devices usually use medium and high-efficiency filters installed at the inlet, exhaust or return air outlets to purify the air, but they do not have the function of sterilization, especially during the operation of the air-conditioning device. It is difficult to guarantee the continuous and effective work of the filter

At the same time, the service life of medium-efficiency filters is generally 3 to 6 months, and the service life of high-efficiency filters is generally about one and a half years. The difficulty of judgment increases and the cost increases

[0005] In view of the above problems, no effective solution has been proposed
