Virus inactivation filter element of fresh air purifier

Abstract

The invention discloses a fresh air purifier virus inactivation filter element which comprises a filter element body, and the filter element body comprises a PET net layer, a carbon net layer and a nanometer sterilization filter layer which are arranged from inside to outside; according to the nanometer sterilization filter layer, nanometer copper ion powder and nanometer titanium dioxide powder are adopted as effective components for resisting bacteria and removing peculiar smell, the effect of inhibiting activity, growth and reproduction of the nanometer sterilization filter layer is achieved, harmful organisms carried in air can be inactivated, almost all organic substances and part of inorganic substances harmful to the human body or the environment are decomposed, and the air quality is improved. Therefore, the antibacterial function, the organic matter degradation function, the air purification function and the self-cleaning function are achieved. The bamboo charcoal filter layer can effectively adsorb bacteria and viruses, and under the synergistic effect of copper ions and nano titanium dioxide powder, bacteria can be more effectively inhibited and sterilized, and peculiar smell can be more effectively removed; the system can be widely applied to fresh air purification systems.

Description

technical field [0001] The present invention relates to the technical field of fresh air purifier filter elements, in particular to an inactivated virus filter element for air fresh air purifiers. Background technique [0002] The fresh air purification system is composed of fans, air inlets, air outlets and various pipes and joints. The fan installed in the ceiling is connected to a series of exhaust outlets through pipes, the fan starts, and the indoor polluted air is exhausted to the outside through the exhaust outlet and the fan, so that a negative pressure is formed in the room, and the outdoor fresh air is installed on the window frame. The upper air inlet enters the room, and while supplying air, the indoor air is filtered, disinfected, sterilized, oxygenated, and preheated. When the exhaust air passes through the main engine, it exchanges heat with the fresh air, and most of the recovered energy is sent back to the room through the fresh air to achieve the purpose o...

AI Technical Summary

Problems solved by technology

Most of the existing fresh air filter elements use ordinary plastic material filter nets for air filtration. Although this structure can meet the needs of users to a certain extent, its disadvantages are: the filtering effect is poor, and it is impossible to intercept and disinfect bacteria and viruses carried in the air.
