Air purification device with filter screen plate employing nano photocatalyst disinfection

Abstract

The invention discloses an air purification device with a filter screen plate employing nano photocatalyst disinfection. The air purification device comprises an air inlet mechanism and a treatment mechanism, wherein the treatment mechanism is arranged at one end of the air inlet mechanism; a fixing block and a pushing block are arranged in a guide rail groove; a spring and an electric push rod are both fixedly installed between the fixing block and the pushing block; the fixing block is connected with the pushing block through the spring and the electric push rod; a stop block is fixedly installed at the bottom of the guide rail groove; a locking part is arranged on the outer surface of the fixing block; the fixing block is connected with the guide rail groove through the locking part; asleeving ring is fixedly installed at one side of the pushing block; and the pushing block is connected with a connecting pile through the sleeving ring. Through extension and retraction of the electric push rod, the pushing block can generate relative displacement, so that an air bag can move, nearby air is introduced into an air bellow, the purpose of accelerating air inflow is achieved, and theair purification efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of air purification equipment, in particular to a nano photocatalyst disinfection air purification device with a filter screen plate. Background technique [0002] Nano-photocatalyst refers to a substance that does not undergo chemical changes itself under light, but can promote chemical reactions. Its function is like chlorophyll in photosynthesis. Anatase nano-TiO2 is the most important photocatalyst material. When it absorbs the energy of sunlight or other light sources, the electrons on the surface of the particles are activated and escape from their original orbits. At the same time, positively charged holes are generated on the surface and escape. The electrons have strong reducibility, while the holes have strong oxidative properties. After the two react with the water vapor in the air, active oxygen and hydroxyl radicals will be generated. Active oxygen and hydroxyl radicals can detoxify most organic...

AI Technical Summary

Problems solved by technology

[0003] The air inlet efficiency of the current air purification device is low, resulting in a slow purification efficiency when purifying the air. Secondly, when using photocatalyst as a catalyst, it is necessary to provide a light source with a wavelength less than 380nm. The current ultraviolet light sources are all fixed. , the reaction efficiency of photocatalyst is slow
