The utility model adopts following technical scheme.Be divided into multistage in the air conditioning purge device and filter, roughing efficiency air filter, medium effeciency filter, TiO are installed behind air outlet successively ₂Clean-up stage; Hot wet treatment apparatus 4 and blower fan, the air after blower fan will filter is sent into air-conditioned room, and circulated air is linked into out between effect filter and the medium effeciency filter.Roughing efficiency air filter 1 is the combination type air filter course of forming with metal filter screen and all-glass paper.TiO ₂Clean-up stage is the supporting mass of processing with water-fast brown paper, and bonding active carbon forms adsorption layer, nano-TiO on supporting mass ₂Be coated with and be attached to activated carbon surface, active carbon and TiO ₂Photochemical catalyst constitutes the cellular monoblock type active carbon-TiO of the sandwich construction with clear opening ₂10, two active carbon-TiO of composite purification net ₂Uviol lamp 11 is arranged between the composite purification net 10.

1) adopting with metal filter screen, all-glass paper at the air-conditioning air outlet is the combined type air port of air filtration layer, when design, increases the area that filters the air port, reduces resistance, reaches energy-conservation purpose.Adopt modular modular filter air port, be convenient to the dismounting and change screen pack, the long-term efficient stable operation of assurance system.

2) be employed in TiO ₂The improved catalyst of middle doping C element has improved air cleaning efficient greatly.Supporting mass, active carbon and the TiO that will process with water-fast brown paper ₂Photochemical catalyst is constructed with the cellular monoblock type purifying net (seeing accompanying drawing 2) of the sandwich construction of clear opening.Supporting mass constitutes hexagon cellular shape hole, and the hexagon length of side is 1mm.Hexagon cellular is as the straight-through duct of light and gas.Bonding active carbon forms adsorption layer on supporting mass.With the butyl polyacrylate breast is glue adhesive agent, and used active carbon is high iodine number burgy such as coconut husk charcoal, the fruit shell carbon etc. between 60～400 orders, will form even, the about 1 centimetre active carbon layer of thickness when supporting.With nano-TiO ₂Powder is dispersed in the water with ultrasonic dispersion, and obtain agglomerate is used above-mentioned TiO with the complex carrier of supporting mass and active carbon formation then greater than the slurry of the solid content W=0.05 of 100nm ₂Slurry dip-coating 3 times is dried by the fire 4h at 160 ℃ down with vacuum condition after each dip-coating.Thereby finally form nano-TiO ₂Be coated with the shell structure that is attached to activated carbon surface.

3) loaded with nano TiO on the air conditioning purge section inwall ₂, be raw material with the tetra-n-butyl titanate, utilize sol-gel process to prepare the aluminium flake loaded with nano TiO of ability photocatalytic degradation ₂Film shines the pollutant in the fillter section of not only can degrading through ultraviolet light, improves purification efficiency.On the inwall load nano-TiO ₂After the film, dust is difficult for deposition, kills the bacterium that adheres on the inwall simultaneously, prevents the generation of secondary pollution.

4) air cleaning section, each functional section all adopt module integrated, for convenience detach and cleaning.Modular segment is respectively: metal filter screen, all-glass paper are the combined type air port section of air filtration layer, electrostatic precipitation section, photocatalytic degradation section.

The utility model has the advantages that:

1) compare with conventional air cleaners, the utlity model has multistage filtration, purification function, purification efficiency is high, and the intermediate product of generation is few.Can effectively strengthen the degerming ability of air cleaning section, prevent the secondary pollution of air-conditioning system.
