Abstract

The present invention discloses one kind of photothermal air purifier with honeycomb structure to eliminate organic pollutant, deodorize and sterilize air. It consists of casing, blower, flow regulating board, polygonal honeycomb-like photocatalytic reactor, ultraviolet lamp, compact heater and corresponding circuit. During operation, the photocatalyst supported by the photocatalytic reactor is activated by the ultraviolet light source and coupled with heat to produce strong oxidizing capacity oxidizing and decomposing the organic pollutant, bacteria, bad smell and harmful inorganic gas in air to reach the aim of purifying air. The honeycomb-like photocatalytic reactor has increased photocatalyst supporting area and raised light illumination. The coupling between the photocatalyst and heat catalytic technology raises the photocatalytic efficiency. The present invention has the advantages of high photocatalytic efficiency, high mineralizing efficiency, etc.

Description

technical field [0001] The invention relates to an air purification device for removing organic pollutants, smog, bacteria, odorous gases and harmful inorganic gases in the air, specifically an air purifier coupled with a photocatalytic reaction device with a honeycomb structure and a compact heat generating device. Background technique [0002] At present, most of the air purifiers used at home and abroad still use mechanical filtration technology, activated carbon adsorption technology, negative ion technology and ozone oxidation technology. The mechanical filter type mainly plays the role of dust removal; the activated carbon adsorption purifier has a certain air purification ability, but there is a problem of adsorption saturation; the negative ion mainly improves the freshness of the air, and at the same time has a weak effect of removing smoke and dust; although ozone has a certain degree of sterilization function, but it is also an air pollutant and will bring new pol...
