System and method for exhausted air sterilization and aeration and comprehensive heating disinfection of highly-contaminated building space

Abstract

The invention provides a system and method for exhausted air sterilization and aeration and comprehensive heating disinfection of a highly-contaminated building space. The system comprises a contaminated area negative pressure metal ventilation pipe, any position thereon communicates with an inlet end of a high-resistance thermal-insulation-layer-carried ventilation pipeline, an outlet end of thehigh-resistance thermal-insulation-layer-carried ventilation pipeline is connected to an inlet end of an outdoor negative pressure metal ventilation pipe through an electric anti-backflow valve, and an outlet end of the outdoor negative pressure metal ventilation pipe is connected with an exhaust port of a high-efficiency variable-frequency fan. Various virus killing devices are sequentially disposed at the rear end of the high-efficiency variable-frequency fan. The system disinfects the air that may contain viruses in the highly-contaminated building space at high temperature through an electric heating pipeline and then guides the air that is disinfected at high temperature to the various outdoor virus killing devices through negative pressure pipelines to diversely and thoroughly disinfect the guided air, thereby thoroughly removing viruses in the air in the highly-contaminated building space.

Description

technical field [0001] The invention relates to a system and method for exhausting, disinfecting, aerating and comprehensively heating and disinfecting highly polluted building spaces, 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-infecte...

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
