Embodiment Construction

[0021] Moderate chemical pollution air photocatalytic purification equipment example structure of the present invention is as shown in Figure 1: technological process:

[0022] The air polluted by medium concentration enters the purification equipment from the air inlet 2, and after being roughly filtered by the mesh screen, it enters the spray system 1 equipped with the spray head 3, and quickly removes the water-soluble or water-absorbed part of the polluted air. substance. And the spray liquid that dissolves or adsorbs some pollutants is stirred in the liquid phase photocatalyst and cavity 14 through continuous gas stirring 6 to obtain floating photocatalytic glass beads or magnetic photocatalytic glass beads 5 for purification treatment, magnetic photocatalytic The catalytic glass beads 5 are purified and recovered by the electromagnetic induction system; the low-concentration polluted air purified by the spray water is sterilized by the ultraviolet lamp 10 and the ozone g...

Abstract

An optically catalytic cleaning apparatus for the air polluted chemically to the medium extent is composed of a casing, a water showering-circulating system consisting of cavity, air inlet filter, showering head and water inlet tube, a solid-phase optical catalyzer consisting of cavity, composite nano-TiO2 photocatalyst, carrier, UV lamp, water-air separator, and negative ion generator, a liquid-phase optical catalyzer consisting of cavity, photocatalytic glass microbeads, gas stirring rod, water outlet system and UV lamp, and an ozone generator.

Description

technical field [0001] The invention relates to photocatalytic purification equipment for chemically polluted air, in particular to a photocatalytic purification unit for moderately chemically polluted air combined with ultraviolet lamps, ozone generators, negative ion generators, water spray treatment and activated carbon adsorption purification units. Catalytic purification equipment. Background technique [0002] The principle of removing organic pollutants in polluted air by using photocatalytic technology is: using semiconductor TiO 2 When the nanomaterial photocatalyst is excited by ultraviolet light, the high-energy charge electron-hole, with the participation of oxygen and water, makes the adsorption and contact on TiO 2 Organic and inorganic particles on the surface of nanomaterial photocatalysts can be photooxidized, photocatalyzed, photoreduced, and photomineralized into CO 2 、H 2 O, H 2 , N 2 or other intermediate products. [0003] TiO 2 Nanomaterial phot...
