Description

Device for preventing and controlling indoor aerosol containing virus and using method thereof

technical field

The invention relates to the field of indoor disinfection and ventilation equipment, in particular to a prevention and control device for indoor aerosols containing viruses and a use method thereof.

Background technique

Liquid or solid particles containing viruses suspended in a gas (such as air) are called viral aerosols. In recent years, emerging respiratory viral infectious diseases, such as SARS, avian influenza, H1N1 influenza, and the new coronavirus, have become a major threat to public health. Most respiratory infectious diseases caused by viruses are carried out between humans and can be transmitted by contact with infected patients or by inhalation of aerosol droplets contaminated by patients. Droplets (aerosol droplets) are released from a person's mouth and nose when a patient breathes, coughs, and sneezes, and for most droplets large enough to settle to the ground, small droplets It is quickly dried and shrinks to form droplet nuclei. The main component of droplet nuclei is biological particles, which have a small diameter and can be suspended in the air for a long time. Biological particulate matter is extremely harmful to humans because it can be inhaled deep into the lungs. When a sufficient dose of infectious microorganisms is present in the droplets, it can infect people. Influenza is contagious both during the incubation period before the onset of the disease and during the onset of the disease. This feature determines that influenza is prone to outbreaks in families, work units, schools, nurseries, and nursing homes, as well as nosocomial infections.

And because people spend most of their time indoors, whether studying, working or resting, a good indoor environment is crucial to good health. Some fans have filters and sterilization functions. However, such devices are mainly used in hospitals and large commercial buildings, and they are expensive and complicated to install, and are not suitable for ordinary civil buildings.

By studying a virus-containing indoor aerosol prevention device and method, the sterilization and ventilation of the indoor air environment can be achieved, thereby improving the indoor air quality, which is of great significance for improving human health and improving the quality of life.
