High-pollution exhaust aeration heating combustion disinfection and sterilization system and method

Abstract

The invention provides a high-pollution exhaust aeration heating combustion disinfection and sterilization system and method. The system comprises a polluted region negative pressure metal ventilationpipe, wherein any position of the polluted region negative pressure metal ventilation pipe is communicated with an inlet end of a high-resistance belt heat insulation layer ventilation pipeline, an outlet end of the high-resistance belt heat insulation layer ventilation pipeline is connected to an inlet end of an outdoor negative pressure metal ventilation pipe through an electric backflow prevention valve, and an outlet end of the outdoor negative pressure metal ventilation pipe is connected to an extraction opening of a high-efficiency frequency conversion fan; and multi-virus disinfectionand sterilization devices are sequentially arranged at the rear end of the high-efficiency frequency conversion fan. Air possibly containing viruses in a high-pollution building space is subjected tohigh-temperature disinfection and sterilization through an electric heating pipeline, then the air after high-temperature disinfection and sterilization is guided to the outdoor multi-virus disinfection and sterilization devices through negative pressure pipelines for diversified thorough disinfection and sterilization of the introduced air, and the viruses in the air in the high-pollution building space can be thoroughly removed.

Description

technical field [0001] The invention relates to a high-pollution exhaust air aeration heating combustion disinfecting system and method, belonging to the field of indoor environment treatment. Background technique [0002] In 2020, the new crown virus is raging around the world, and it is necessary to eliminate the places where a large number of people infected with the virus have been active, so as to avoid the further spread of the virus. Viruses can easily survive for a long time in wet and cold environments, especially in airtight underground spaces or aboveground spaces where external windows cannot be opened. How to ventilate the enclosed building space and avoid secondary pollution caused by virus leakage has become a problem that needs to be solved in the industry. [0003] For example, the underground trading hall of a certain wholesale market has become a high-risk area after the emergency evacuation of virus-infected merchants. The possibility of viruses and met...

AI Technical Summary

Problems solved by technology

[0004] Studies have shown that viruses can spread in the form of aerosols. The diameter of the new coronavirus is 60nm-220nm, and it has a strong ability to survive in a humid and low temperature environment. It is difficult and costly to completely filter the new coronavirus through the existing high-efficiency filters. And it is impossible to disinfect the new crown virus, which may easily lead to incomplete filtration or secondary transmission

Moreover, the air duct in the uncontaminated area in front of the filter also lacks effective disinfecting methods after being polluted by viruses
