A fresh air unit with purification, sterilization and disinfection functions and its purification, sterilization and disinfection process

Abstract

The invention discloses a fresh air unit with purifying, sterilizing and disinfecting functions and its purifying, sterilizing and disinfecting process, which comprises an inlet chamber, a gas purification chamber, a gas heating and disinfection chamber, a gas mixing chamber, a fan chamber, and an air outlet chamber from bottom to top. There are air inlets on the four side walls of the gas chamber, a filter installation port on one side of the gas purification chamber, and a filter seal on the outside of the filter installation port, a gas purification filter installed in the gas purification chamber, and a gas heating and disinfection chamber on all four sides. The wall is provided with a heat insulation layer, and a heating plate is installed inside the gas heating and disinfection chamber, and catalytic ceramic particles are filled between the heating plates, a porous partition is installed on the top of the gas heating and disinfection chamber, and an air supply port is opened on the opposite side wall of the gas heating and disinfection chamber. , There is an air supply regulating plate outside the air supply port, and an air mixing fan is installed inside the air mixing chamber. The fresh air unit with purification and disinfection functions of the present invention can effectively remove harmful gases such as particulate matter and VOC in the air, kill microorganisms such as bacteria and viruses in the air, purify and disinfect the air, and can also be used for heating in winter.

Description

technical field [0001] The invention belongs to the technical field of air purification and regulation, and in particular relates to a fresh air unit with purification, sterilization and disinfection functions and a purification, sterilization and disinfection process thereof. Background technique [0002] Pathogens such as bacteria and viruses survive longer in cold and humid environments and are more likely to spread among people, which is the main reason for the frequent occurrence of respiratory diseases in winter. When a person infected with the virus breathes, speaks, coughs, sneezes, etc., it produces droplets that carry pathogens. Droplets dry quickly in the air and can remain suspended in the air for a long time, forming aerosols. Aerosols may be inhaled through the respiratory tract and cause new infections. In addition, the current treatment methods for gaseous pollutants such as formaldehyde and toluene in indoor air are mostly activated carbon adsorption, the ...

AI Technical Summary

Problems solved by technology

In addition, the current treatment methods for gaseous pollutants such as formaldehyde and toluene in indoor air are mostly activated carbon adsorption, the adsorption capacity is limited, and it is easy to release after adsorption saturation, causing secondary pollution

Catalysts are used to catalyze the decomposition of VOC harmful gases such as formaldehyde and toluene. The catalytic effect is poor at room temperature. The suitable catalytic decomposition temperature usually needs to be above 200°C. It is difficult for conventional household air purification equipment to reach such a high temperature, which restricts the use of catalytic decomposition technology in indoor air.
