Abstract
The invention aims to provide a photocatalyst air purifier adopting a new structure. By the aid of the purifier, formaldehyde in air flows of the air entering the purifier can be decomposed under the combined action of ultraviolet light and a titanium dioxide photocatalyst. The overall purifier is in a long column shape, so that the contact rate of the formaldehyde and the photocatalyst is increased. In order to remove contamination particles in the air simultaneously, assemblies with the particle filtering capability are also added on the premise that decomposition of the formaldehyde is guaranteed.
Description
Technical field:
The present invention relates to a kind of column photo-catalytic air cleaner and design feature thereof.
Background technology:
Along with the quick increase of domestic automobile quantity and developing rapidly of industry, the air pollution of hinterland is more and more serious.In east, many areas have occurred that serious haze pollutes, the health that has endangered the people.And the formaldehyde pollution event of multiexposure, multiple exposure has also been beaten alarm bell to people in recent years, make people more and more pay attention to indoor Environmental Health.Especially for newly-decorated house, the health of damaging the person of moving in that formaldehyde pollution is serious.
Mostly commercially available air purifier is take that multiple filtration and charcoal absorption are as main at present, such as commercially available Philip AC4074 and Yadu KJG2104 etc. all belongs to this type, multi-layer filtrating equipment has good filtration for particle, but there is no large impact for the removal of formaldehyde.Although and absorbent charcoal adsorber can adsorb certain formaldehyde, there is absorption saturability in it, and itself only can adsorb harmful substance, can not decompose and remove harmful components.
Photocatalyst of titanium dioxide is a kind of outstanding catalysis material, can well remove airborne formaldehyde composition under UV-irradiation.A small amount of commercially available air purifier has also utilized this technology, Buddhist WH10600C-A photo-catalytic air cleaner recklessly for example, but the fore-and-aft direction that its airflow direction is machine, the air-flow entering is got back in atmosphere by filter screen soon, and remain to be discussed the time of contact of photocatalyst.
Summary of the invention:
The object of the present invention is to provide a kind of photo-catalytic air cleaner of column structure, make the air that enters clarifier inside under the irradiation of ultraviolet light, to produce enough frequency of exposure with inner photocatalyst of titanium dioxide, thereby can decompose completely airborne formaldehyde and other organic principles.And for the energy airborne particle contamination of removal simultaneously, in the present invention, guaranteeing, under the prerequisite of Formaldehyde decomposition, also to have added the assembly with contamination particle in filtered air.And the column structure of this clarifier employing, make ultraviolet lamp tube be positioned at clarifier centre position, can utilize fully ultraviolet source.In addition, this clarifier integral body is rectangular column, thereby this clarifier can colourful gesture be placed, and does not take space within doors.
Accompanying drawing explanation:
Fig. 1 is the structural representation of column photo-catalytic air cleaner.Wherein: 1, control circuit; 2, Hepa filter screen; 3, outgassing groove; 4, grid hole; 5, active carbon filter net; 6, fan; 7, fluorescent tube stiff end; 8, load has the foldable layer of titanium dioxide; 9, ultraviolet lamp tube; 10, temperature sensitive resister.Main part is the foldable layer (8) that ultraviolet lamp tube (9) and load have titanium dioxide.During this equipment operation, air-flow sucks from below through fan (6), first passes through the filtration for the first time of active carbon filter net (5), and air-flow enters clarifier uviol lamp part.Air-flow under the acting in conjunction of fan (6) and below fan (6), has the foldable layer (8) of titanium dioxide upwards to flow along load up.Simultaneously under the irradiation of ultraviolet lamp tube (9), load has the titania nanoparticles on the foldable layer (8) of titanium dioxide to be excited, by the Formaldehyde decomposition in air-flow.Air-flow after treatment with ultraviolet light successively through top fan (6), through top activated carbon net (5) with after Hepa layer (2) filters, discharge clarifier, enter into atmosphere.Acting as of temperature sensitive resister in Fig. 1 (10) prevents that the long-time unlatching of clarifier is rear overheated, when temperature sensitive resister (10) detects excess Temperature, and can automatic powered-down.Design sketch when vertically place for this invention in Fig. 1 left side.
Design sketch when Fig. 2 laterally places for this clarifier.For symmetry attractive in appearance, can install screen pack additional at its inlet end, and can better play the effect of filtering molecule.
Fig. 3 is the structural representation of the foldable layer that in Fig. 1, load has titanium dioxide (8).Its preparation method is: the paper that art post paperboard or other are had to some strength, as being substrate, becomes flabellum shape by this folding cardboard, as Fig. 3 1. as shown in.Spraying binder in its one side, then covers nano titanium dioxide powder it on, to be bonded dose dry after, by unnecessary titania powder vibration removal, just obtained the flabellum shape cardboard that load has nano titanium dioxide powder.By this cardboard to load have the one side of titanium dioxide crooked, docking, can obtain a barrel-like structure, as Fig. 3 3. as shown in.The inner surface of this barrel is the one side of carried titanium dioxide, and the space surrounding in the middle of bucket is for placing the region of ultraviolet lamp tube.Air-flow enters after this structure, and air-flow can be under the effect of upper and lower fan, upwards flows along adding in layer of paper web and ultraviolet lamp tube.
Fig. 4 is this invention circuit diagram.Wherein: 1, master switch; 2, temp control switch; 3, ultraviolet lamp tube; 4, temperature sensitive resister; 5, transforming circuit and total control circuit; 6, fan.Wherein the effect of temp control switch is: it is overheated while preventing from opening for a long time this equipment, can to occur, and when temperature sensitive resister detects device interior excess Temperature, temp control switch just can off device power supply.
Fig. 5 is the another kind of frame mode of the foldable layer that in Fig. 1, load has titanium dioxide (8).Its preparation method is: a cardboard is carried out to cutting by Fig. 5 shown in 1., and the dotted portion of Fig. 5 in is 1. cutting wires.At cardboard back spraying coating adhesive after cropped, and carried titanium dioxide nanometer powder, as Fig. 5 2. as shown in.To be bonded dose dry after, the triangle scraps of paper that cut out are turned down to front, obtained as the cardboard of the fish scale structure shape of Fig. 5 as shown in 3..This cardboard, to positive crooked, the docking of cardboard, is formed to the cylinder-like structure that there are a lot of triangle projections an inside, and 4. Fig. 5 is this cylinder top view.Wherein cylinder center is uviol lamp put area.
