Fresh air handling unit with purification, sterilization and disinfection functions and purification, sterilization and disinfection process thereof

Abstract

The invention discloses a fresh air handling unit with purification, sterilization and disinfection functions and a purification, sterilization and disinfection process thereof. The fresh air handling unit comprises an air inlet chamber, a gas purifying chamber, a gas heating and disinfecting chamber, a gas mixing chamber, a fan chamber and an air outlet chamber from bottom to top. Air inlets are formed in the four side walls of the air inlet chamber, and a filter screen mounting opening is formed in one side of the gas purifying chamber. A filter screen sealing element is arranged outside the filter screen mounting opening. A gas purification filter screen is mounted in the gas purifying chamber, heat insulation layers are arranged on the four side walls of the gas heating and disinfecting chamber, heating plates are mounted in the gas heating and disinfecting chamber, catalytic ceramic particles are filled between the heating plates, and a porous partition plate is mounted at the top of the gas heating and disinfecting chamber. An air supplementing opening is formed in the opposite side wall of the gas mixing chamber, an air supplementing adjusting plate is arranged outside the air supplementing opening, and a gas mixing fan is installed in the gas mixing chamber. The fresh air handling unit with the purification and disinfection functions can effectively remove particulate matter, VOC and other harmful gases in the air, kill bacteria, viruses and other microorganisms 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.
