Air filtration and sterilization device for eliminating harmful gas

Abstract

The invention provides an air filtration and sterilization device for eliminating harmful gas. The air filtration and sterilization device for eliminating harmful gas is applied to indoor air purification and comprises a box body, a filter, a plate-type low-temperature plasma, an ozone filter and a fan device, wherein the filter, the plate-type low-temperature plasma, the ozone filter and the fan device are sequentially arranged in the box body side by side. The fan device is used for sucking air into the box body and blowing out the air after the air is treated by the filter, the plate-type low-temperature plasma and the ozone filter. The filter, the plate-type low-temperature plasma, the ozone filter and the fan device are sequentially arranged in the box body side by side, and the fan device sucks the air into the box body and blows out the air after the air is treated, so that the air filtration and sterilization device treats inhalable particles and harmful gas in the air entering the box body and performs stepless regulation to air volume for air cleaning by controlling the rotating speed of a motor. An application range of air filtration and sterilization is greatly widened, energy consumption of the device is reduced, the harmful gas in the air can be eliminated, and the harmful gas concentration in the air is controlled within the scope of national standard.

Description

technical field [0001] The invention relates to the field of air purification equipment, in particular to a device for filtering and sterilizing indoor air to eliminate harmful gases. Background technique [0002] In recent years, air pollution has become increasingly serious. The world index is that PM2.5 (particles with a diameter of ≤ 2.5 microns) is less than 10, which is a safe value, while it is higher than 50 in most parts of my country. Poor air quality seriously affects human health. Therefore, it is necessary to effectively filter and sterilize the outdoor air entering the room to purify the air to protect human health. [0003] At present, the air filter materials used in the filters on the market are mostly non-woven fabrics, which have low filtration efficiency and poor purification effect, or use high-efficiency filter paper, which has large air resistance and short service life. Under the circumstances, the air filter material of the existing filter can no lo...

AI Technical Summary

Problems solved by technology

Activated carbon is a very good adsorbent for harmful gases. Its disadvantages are that the air resistance is large, and the second is that it cannot be regenerated after being saturated; air ionization technology includes low-temperature plasma, air negative ion body and high-voltage generator, etc. The best technology for harmful gases. At present, the biggest obstacle is that a large amount of ozone will be generated during the air ionization process, which will form secondary pollution and affect human health. At the same time, the high-voltage generator is large in size and is not suitable for small purification devices.
