Description

Photo-catalyst, deodorant clean air package

This utility model relates to a kind of light-catalyzed reaction sterilization, deodorant clean air package of utilizing, and belongs to the architecture advances of the photocatalysis air cleaning device that has occurred.This assembly can be used as the clean air package of air purifier, air conditioner and automobile-used blower etc.

The photocatalysis air purifying device that photocatalysis air purifying device that occurred, representational such as practical novel C N 2114787 are invented, its structure as shown in Figure 1.It is made up of filter, reaction tube, air exhauster, radome etc.The disk (Fig. 2) of adsorber for being pressed into by active carbon has some through holes that become 25 ° 6 millimeters of diameters with main shaft on the sheet.Through hole is as gas passage and have the effect that air-flow leads concurrently.Owing to oblique importing of air-flow and interference mutually, make gas molecule and photocatalyst surface repeatedly collide absorption and generation light-catalyzed reaction like this.Catalytic bed adopts aluminum or boils through peracid, and the glass cloth that washing is handled is made.Boil through peracid to adopt, the glass cloth that washing is handled is made catalytic bed the best.Though this device has considered that air-flow guiding problem is to increase contacting of gas molecule and photocatalyst, but airflow direction is surperficial parallel with the photocatalysis bed still basically, because cavity cross section is big, a large amount of gas is discharged soon, and can not arrive the surface reception light-catalyzed reaction effect of photocatalysis bed.Especially catalytic bed adopts and boils through peracid, and the glass cloth that washing is handled is made, and not only life-span weak point, and glass fabric can destroy, be dispersed into tiny glass fibre gradually and be blown out by air-flow, causes the new pollution of serious harmful health.

The purpose of this utility model is to provide a kind of improved photocatalysis air-cleaning assembly, the pollution that this assembly can improve purification efficiency, simplified structure, increase service life and avoid glass fibre etc. to cause.

The purpose of this utility model realizes as follows: have the porous plate of a large amount of through holes or tubing and constitute cavity around being assemblied in Burdick lamp with fixture, leave the air vent that has purified air for discharging on one end of cavity or a surface, applying titanium dioxide optical catalyst on the inner surface of porous plate or tubing.Gas to be clean is directed on the inner surface that is applying titanium dioxide optical catalyst by porous plate or the tubing mode with countless tiny air-flows, titanium dioxide optical catalyst generation light-catalyzed reaction under the exciting of the ultraviolet light that Burdick lamp sends, kill antibacterial and viral, decomposition Organic substance wherein in the air-flow, and can be promptly NO _xOxidation is removed.Dirty gas becomes clean air through the processing of photo-catalyst of the present utility model, odor removal.

Advantage of the present utility model and good effect are: use porous plate with a large amount of fine connectivity pores or tubing as the gentle flow point of the carrier of the photocatalyst director element that looses, changed the type of flow of air-flow up hill and dale, not only increase the contact area of gas and photocatalyst, and greatly increase air pollution and accept the probability that light-catalyzed reaction is purified; Reduced element simultaneously, catalytic bed long service life and the pollution of having avoided the glass fibre catalytic bed to cause.

Below in conjunction with accompanying drawing and example this utility model is further described.

Fig. 1 is the structure chart of the photocatalysis air purifying device invented of CN 2114787.

Fig. 2 is the structure chart of the active carbon adsorber of the photocatalysis air purifying device invented of CN 2114787.

Fig. 3 is structural representation of the present utility model and local enlarged diagram.

Fig. 4 is the enforcement illustration that this utility model is used for air-conditioner.

In the accompanying drawing 3, fixture [3] is enclosed in Burdick lamp [2] fitted around to the pipe of the porous material with a large amount of through holes or sheet material [1] and becomes cavity, one end of cavity leaves the air vent that has purified air for discharging, and is applying titanium dioxide optical catalyst [4] on the inner surface of porous material [1].Gas to be clean is directed on the inner cavity surface that is applying titanium dioxide optical catalyst [4] by the mode of porous material [1] with countless tiny air-flows, titanium dioxide optical catalyst generation light-catalyzed reaction under the exciting of the ultraviolet light that uviol lamp [2] sends, kill antibacterial and viral, decomposition Organic substance wherein in the air-flow, and can be promptly NO _xOxidation is removed.Dirty gas becomes clean air through the processing of photo-catalyst of the present utility model, odor removal.Porous material [1] is not only the carrier of photocatalyst, and play the effect that makes air dispersion and guiding, the huge specific surface area of porous material [1] helps absorption, concentrates harmful gas simultaneously, thereby improves the light-catalyzed reaction clean-up effect significantly, and simplifies the structure greatly.Assembly of the present utility model is kill bacteria, virus and acarid effectively, and removes spatial trace harmful gases such as room, hospital and deodorization, elimination nitrogen oxide.This assembly can be used for air purifier, air conditioner and automobile-used blower etc.Because this assembly is mounted in air-conditioner or the air purifier, so assembly itself does not have ventilation units such as blower fan.

Fig. 4 illustrates this utility model photo-catalyst, the deodorization clean air package is installed in a kind of embodiment in the air-conditioner.

Clean air package uses three porous glass plates [5] to form cavity, and the size of porous glass plate is 400mm * 200mm * 10mm, and ventilation porosity 〉=70% all is coated with photocatalyst and forms photocatalysis layer [4] on the inner cavity surface of every porous glass plate.Ultraviolet source is the quartz uv lamp pipe [2] of voltage 220V, power 15W.The air pollution that enters air-conditioner is by behind the common filtration, purification of air-conditioner, pass through hot and cold exchanger [7] again and regulate temperature, humidity, under the effect of blower fan [6], pass through porous glass plate [5], disperseed, guided arrival photocatalysis coating [4] to locate, by ultraviolet excitation titanium dioxide optical catalyst generation light-catalyzed reaction, kill antibacterial and viruses such as escherichia coli, Staphylococcus aureus, and the skeleton of a corpse of decomposing bacteria and virus, decompose harmful gass such as airborne harmful Organic substance such as formaldehyde, acetaldehyde, methanthiol, eliminate stink.Air-conditioner is sent the air of sterilization, deodorization, comfortable, has improved living environment.

Use another embodiment of this assembly to be: this utility model is installed on the automobile air-supply arrangement, uses the carrier of porous ceramics pipe fitting as photocatalyst, and it is of a size of diameter 100mm * long 180mm * thick 8mm, ventilation porosity 〉=70%.Inner cavity surface is coated with titanium dioxide optical catalyst.Ultraviolet light source is the quartz lamp of voltage 12V, power 8W.Under the exciting of ultraviolet light, titanium dioxide optical catalyst produces light-catalyzed reaction, and sterilization, deodorization especially can be removed nitrogen oxide, reduces the concentration of nitrogen oxide in the car significantly.
