High-contamination exhaust multi-disinfecting-killing system and method

Abstract

The invention provides a high-contamination exhaust multi-disinfecting-killing system and method. The system comprises a contaminated area negative-pressure metal vent pipe, any position on the contaminated area negative-pressure metal vent pipe communicates to the inlet end of a high-resistance tape heat insulating and insulating layer vent pipeline, the outlet end of the high-resistance tape heat insulating and insulating layer vent pipeline is connected to the inlet end of an outdoor negative-pressure metal vent pipe through an electric anti-backflow valve, and the outlet end of the outdoornegative-pressure metal vent pipe is connected to an exhaust port of an efficient variable-frequency fan. Multiple virus disinfecting and killing devices are sequentially arranged at the rear end ofthe efficient variable-frequency fan. Firstly, air probably containing viruses in high-contamination building spaces is disinfected and killed at high temperature through an electric heating pipeline,then the air disinfected and killed at high temperature is exhausted to the outdoor multi-virus disinfecting and killing devices through a negative-pressure pipeline, the introduced air is completelydisinfected and killed diversely, and therefore the viruses in the air of the high-contamination building spaces can be completely removed.

Description

technical field [0001] The invention relates to a high-pollution exhaust air multiple elimination 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 methane cannot be ruled...

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
