Description
Technical field
The present invention relates to chemical contamination air photocatalysis and purification equipment, be particularly related to the employing light catalytic purifying, with ultraviolet lamp, ozone generator, anion generator, the moderate chemical contamination air photocatalysis and purification equipment that the water spray is handled and the charcoal absorption clean unit combines.
Background technology
Utilize photocatalysis technology to handle, the organic pollution principle is in the removal contaminated air: utilize semiconductor TiO
2The nano material photochemical catalyst in the presence of oxygen and moisture content, makes absorption, contact at TiO during by energetic charges electronics that ultraviolet excitation produced-hole
2The organic and inorganic particulate of nano material photocatalyst surface can photooxidation, photocatalysis, photo-reduction, light mineralising become CO
2, H
2O, H
2, N
2Or other intermediate product.
TiO
2The nano material photochemical catalyst is a present application study photochemical catalyst the most widely, TiO
2Nano material can be made nontoxic food additives.Ti
4+Be the lower toxicity material, do not have tangible cumulative function, no mutagenicity, chronic toxicity activity are 1.08 mg/litre.In the light reaction process, be not dissolved into Ti
4+Remove low concentration chemistry organic pollution in the air, adopt the purified treatment of ' gas-solid-phase photocatalyst ', become at present application technology the most widely.But adopt ' gas-solid phase t iO2 nano material photochemical catalyst, in removing contaminated air during the higher concentration organic pollution, the higher concentration organic pollution since during photocatalysis catalytic reaction slower, be easy to produce the intermediate product of secondary, solia particle is topped at TiO in intermediate product or the air
2The surface of nano material photochemical catalyst causes TiO
2A large amount of inactivations of nano material photochemical catalyst.Therefore, utilizing TiO at present
2The nano material photochemical catalyst is removed the practicability technology popularization aspect that the higher concentration pollution is handled in the air, has suitable difficulty.The photocatalysis in solid phase air purifier that causes existing market to be sold can not extensively be promoted.
Active carbon, medical stone, vermiculite, zeolite are all to the dust in the empty G﹠W, dissolved impurity and dissolved impurity, particularly heavy metal ion all do not have suction-operated preferably.For the microorganism that exists in air, the water, bacterium, virus etc., adopt ultraviolet ray, ozone and anion that it is had the ability of well killing, but, water has interception, absorption, overslaugh effect to ultraviolet light, ozone, anion, so ultraviolet light, ozone and anion all are difficult for purification of water quality is carried out advanced treating.
TiO
2Photocatalyst material has absorbability preferably to light, utilizes semiconductor TiO in water
2The light catalytic purifying technology of nano material photochemical catalyst is handled the higher concentration organic contamination, and during chemical contamination, efficient is better.Solia particle enters in the water in the intermediate product of secondary, intermediate product or air, is difficult for topped at TiO
2Therefore the surface of nano material photochemical catalyst can not cause TiO
2A large amount of inactivations of nano material photochemical catalyst, thus can the organic contamination of high efficiency photocatalysis treatment higher concentration, chemical contamination.But, because present widely used TiO
2The nano material photochemical catalyst is difficult for reclaiming and repeated application in water, causes the photochemical catalyst consumption big, and equipment cost increases, and operating efficiency is very low.So photocatalysis treatment organically-polluted water practicability technical elements also has certain degree of difficulty at present.Only can purify aspect small-scale application such as dyeing and printing sewage purification at electroplating sewerage.
And the glass microballoon of the disclosed a kind of high adsorption photocatalysis performance of employing ZL031253598, the disclosed photocatalyzing magnetic float microbead patented technology of ZL021156484 increases TiO
2The nano material photochemical catalyst is floating or be suspended in function of water body, increases photochemical catalyst paramagnetic performance, can better reclaim photochemical catalyst, reaches repeated application purpose for a long time.Because this TiO
2Therefore nano material photochemical catalyst floatability or be suspended in water body, is using this composite Ti O
2During the nano material photochemical catalyst, can save machine power in a large number, reduce equipment volume, reduce cost, can improve the light catalytic purifying operating efficiency, reach higher concentration organic pollution purpose in the quick removal water.
