Embodiment Construction

[0022] Such as figure 1 , figure 2 As shown, the plasma-based human microenvironment epidemic prevention equipment mainly includes: 1. Air inlet, 2. Air supply outlet, 3. The first centrifugal fan, 4. The first plasma generating device, 5. AC power supply, 6. . The second centrifugal fan, 7. DC power supply, 8. The first circuit board, 9. The pressure sensor, 10. The step adjustment switch, 11. The second plasma generating device, 12. The second circuit board. The system is divided into fan air supply system, power supply system and purification and sterilization system.

[0023] Principle and idea: According to data, whether it is airborne or contact transmission, the virus survives in the air or on the surface of objects for a long time, which has a great impact on the spread of the virus and increases the chance of the virus spreading from person to person. risk. Low-temperature plasma can inactivate viruses by generating heat, free radicals, and charged particles at at...

Abstract

The invention relates to a method for purifying air pollutants, and belongs to the field of plasma sterilization. Under the background of global epidemic situations, reduction of virus transmission and reduction of infection risks of people are extremely urgent, even though traditional sterilization and disinfection modes including high-temperature and high-pressure sterilization, ultraviolet sterilization, ozone disinfection and the like have certain effects, thermal comfort of human bodies is influenced, and the traditional sterilization and disinfection modes are harmful to human health and are poor in economical efficiency. A plasma technology is adopted, and biological aerosol rapid killing in the air is achieved within the range of 1-2 m<2> of a human body breathing area. Meanwhile, as the head of a person is within a plasma cloud protection range, bacteria attached to the body clothes, the face and the outer surface of a mask can be killed, so that harm possibly caused by air path propagation or contact propagation is resisted, and mobile protection of man-machine coexistence is achieved.

Description

technical field [0001] The invention relates to a method for purifying air pollutants, and belongs to the fields of HVAC, air cleaning technology and plasma sterilization. Background technique [0002] According to the World Health Organization (WHO), the most common infectious disease in the world is respiratory infection. These infections arise from bacterial or viral contact and can be spread in indoor settings in a number of different ways, including direct or indirect contact with infected surfaces, droplet transmission, or aerosol transmission. Aerosol transmission is defined as host inhalation of infectious nuclei (less than 5 µm in diameter) that remain suspended in the air and spread in indoor environments. Due to the existence of indoor pollution sources, considering that people usually spend more than 90% of their time indoors, they are exposed to pollution sources for a long time, which greatly increases the risk of people contracting diseases and poses a threat...
