Description
Technical field
This utility model relates to photocatalysis air purifying device.
Background technology
Existing air purifier adopts the purification techniques such as filtration, absorption mostly, it does not have the harmful gass such as PARA FORMALDEHYDE PRILLS(91,95), ammonia, benzene and benzene homologues carry out catalytic decomposition, it is impossible to effectively remove the noxious pollutant in air.
For solving the problems referred to above, this utility model provides a kind of air purifier that will filter, adsorb and photocatalysis combines.Photochemical catalytic oxidation is based on photocatalyst and produces activated state oxygen under the action of uv light, and the harmful gas oxidation Decomposition in air is become the material such as carbon dioxide and water.
Summary of the invention
In order to overcome drawbacks described above, this utility model provides a kind of photocatalysis air purifying device, and this depurator can make full use of light source and catalyst, and comprises activated carbon filtration, and purification efficiency is high, good purification.
This utility model is achieved through the following technical solutions:
A kind of photocatalysis air purifying device, including housing 1, air inlet 2, air outlet 8, blower fan 7, photocatalysis room 10, filtering dust net 3, activated charcoal strainer 6, ultraviolet light source 5, microwave generator 9, air inlet 2 is positioned at housing 1 lower end side, filtering dust net 3 is set gradually from the bottom up in the middle part of housing 1, photocatalysis room 10, activated charcoal strainer 6, air outlet 8 is positioned at housing 1 upper side, photocatalysis room 10 descends two ends to be provided with photocatalyst metal filter screen 4 thereon, ultraviolet light source 5 is located in photocatalysis room 10, between photocatalyst metal filter screen 4, microwave generator 9 is arranged on housing 1 sidewall to launch microwave in photocatalysis room 10.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
1-housing, 2-air inlet, 3-filtering dust net, 4-photocatalyst metal filter screen, 5-ultraviolet light source, 6-active carbon filter net, 7-blower fan, 8-air outlet, 9-microwave generator, 10-photocatalysis room.
Detailed description of the invention
For making the purpose of this utility model, technical scheme and advantage clearly, below in conjunction with accompanying drawing, this utility model embodiment is described in further detail.
As shown in Figure 1, photocatalysis air purifying device includes housing 1, air inlet 2, air outlet 8, blower fan 7, photocatalysis room 10, filtering dust net 3, activated charcoal strainer 6, ultraviolet light source 5, microwave generator 9, air inlet 2 is positioned at housing 1 lower end side, filtering dust net 3 is set gradually from the bottom up in the middle part of housing 1, photocatalysis room 10, activated charcoal strainer 6, air outlet 8 is positioned at housing 1 upper side, photocatalysis room 10 descends two ends to be provided with photocatalyst metal filter screen 4 thereon, ultraviolet light source 5 is located in photocatalysis room 10, between photocatalyst metal filter screen 4, microwave generator 9 is arranged on housing 1 sidewall to launch microwave in photocatalysis room 10.Photocatalyst is Nano titanium dioxide.Microwave generator 9 uses the microwave generator that commercially can buy.
Air purifier of the present utility model is additionally provided with microwave generator 9 on the sidewall of its housing 1, launching microwave in photocatalysis room 10, utilize microwave that the air come in is sterilized, irradiation under ultraviolet ray is at photocatalyst drainage screen, wherein harmful gas is by catalytic oxidation, becomes carbon dioxide and water.Adopting microwave disinfection is utilize microwave field to make the temperature of organism raise, protein denaturation, so that organism loses activity, and, the ion stream of microwave field sensing, can affect the CHARGE DISTRIBUTION near cell membrane, cause that the barrier action of film sustains damage, the eubolism of interference or destruction cell, causes bacterial growth to suppress, stops or dead.
Microwave field is introduced optically catalytic TiO 2 reaction, light-catalyzed reaction is produced the effect of four aspects: increase titanium-dioxide photo and absorb, suppress the compound of carrier, promote the desorption of water and promote that surface hydroxyl generates free radical.Research finds, titanium deoxide catalyst is under the radiation of microwave, and the specific activity of photochemical catalytic oxidation decomposing organic matter does not have the photocatalytic activity under microwave action to be significantly improved.
Owing to microwave radiation excess can be harmful, therefore microwave generator of the present utility model is simply to photocatalysis indoor transmitting microwave, photocatalysis room 10 is arranged in the middle part of purifier shell 1, two ends are provided with photocatalyst wire netting, wire netting enables air to flow through on the one hand, contact with photocatalyst, microwave from leakage can be prevented again on the one hand, human body is worked the mischief.This utility model utilizes ultraviolet light, microwave, photocatalytic degradation and adsorption filtration to work in coordination with integration filter disinfectant degradation toxic organics effect, and clean air, this air purifier is better than the clean-up effect of independent photocatalysed purifier.
The foregoing is only preferred embodiment of the present utility model, not in order to limit this utility model, all within spirit of the present utility model and principle, any amendment of making, equivalent replacement, improvement etc., should be included within protection domain of the present utility model.
