Method and equipment for effectively deactivating viruses

Abstract

The invention belongs to the technical field of prevention and treatment on novel coronavirus and particularly discloses a method and equipment for effectively deactivating viruses. The method comprises the steps: S1. carrying out charging treatment on aerosol possibly containing pathogens; S2. applying an external electric field to the charged aerosol, so as to collect the aerosol in the presenceof an electric field force; and S3. carrying out virus killing treatment on the collected aerosol to destroy RNA structures of the viruses in the aerosol, thereby effectively deactivating the viruses. According to the method and the equipment, charged high-voltage line poles charge the aerosol possibly containing the pathogens through a pulsed high-voltage power supply, the external electric field is applied to the charged aerosol to collect the charged aerosol in the presence of the electric field force, meanwhile, the collected aerosol is irradiated with powerful ultraviolet radiation to destroy the RNA structures of the viruses in the aerosol and enable the pathogens in the aerosol to lose reproduction capability or activity, and thus, the viruses are effectively deactivated.

Description

technical field [0001] The invention belongs to the technical field of novel coronavirus prevention and control, and more specifically relates to a method and equipment for effectively inactivating viruses. Background technique [0002] According to the "Pneumonia Diagnosis and Treatment Plan for Novel Coronavirus Infection (Trial Version 5)" issued by the National Health and Medical Commission, the main transmission route of the new coronavirus is through respiratory droplets and contact transmission. When a patient coughs or sneezes, as many as 1.05 million droplets with a diameter of 0.5 microns to 12 microns can be discharged at a single time, and the spray distance can reach several meters. The droplets with larger particle size are not affected by the flow of the gas phase, and the falling speed is faster, and they can settle within a distance of 1 meter to 2 meters, while the smaller droplets can continue to float in the air with the airflow , Once inhaled, it will p...

Problems solved by technology

Ordinary filters cannot achieve high-efficiency filtration of aerosols below 1 micron. Although HEPA (High efficiency particulate air Filter, high-efficiency air filter) filters have high filtration efficiency, they have high wind resistance and high system requirements. The net is still a HEPA filter. After a certain period of use, the surface is likely to cause virus accumulation or microbial growth, making the purification device itself a source of pollution, and the indoor air quality further deteriorates.
