Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, be clearly and completely described the technical scheme in this utility model embodiment, obviously, described embodiment is only this utility model part embodiment, instead of whole embodiments.
A kind of waste gas treatment equipment adopting ultraviolet catalytic technology of embodiment as shown in Figure 1, the discharge pipe 5 comprising gas sampling cover 1, connect the gas sampling pipe 2 of gas sampling cover 1, connect the photo-catalytic deodorizing device 3 of gas sampling pipe 2, connect the centrifugal blower 4 of photo-catalytic deodorizing device 3, connect centrifugal blower 4.
Photo-catalytic deodorizing device 3 comprises air inlet and gas outlet, and air inlet connects gas sampling pipe 2, and gas outlet connects centrifugal blower 4; From air inlet to gas outlet, photo-catalytic deodorizing device 3 inside is provided with common filtering module 31, first nano titanium oxide catalytic module 32, UV-module 33, second nano titanium oxide catalytic module 34 and activated carbon filtration module 35 successively.Photo-catalytic deodorizing device 3 inside is provided with photocatalysis chamber, and the first nano titanium oxide catalytic module 32, UV-module 33, second nano titanium oxide catalytic module 34 are located in photocatalysis chamber.Common filtering module 31 is located at air inlet position, and activated carbon filtration module 35 is located at position, gas outlet.
Common filtering module 31 is for being provided with the drainage screen of filter cotton, and filter cotton Main Function is dust and partial particulate thing in removing waste gas, and ensures the steady of air-flow.First nano titanium oxide catalytic module 32 and the second nano titanium oxide catalytic module 34 are nano-titania photocatalyst carrier, and UV-module 33 is at least two quartz burners with nano-titania photocatalyst carrier combination.Quartz burner is the quartz burner of characteristic wavelength 185nm and the quartz burner of characteristic wavelength 254nm.Activated carbon filtration module 35 is for being provided with the activated carbon filtration cotton of active carbon.
As further illustrating the present embodiment, the workflow of the present embodiment is now described: waste gas, under the traction of centrifugal blower 4, enters in photo-catalytic deodorizing device 3 from gas sampling cover 1 through gas sampling pipe 2; In photo-catalytic deodorizing device 3, waste gas is successively through common filtering module 31, first nano titanium oxide catalytic module 32, UV-module 33, second nano titanium oxide catalytic module 34 and activated carbon filtration module 35, then discharges through centrifuge and discharge pipe 5.
As further illustrating the present embodiment, the operation principle of the present embodiment is now described: in photo-catalytic deodorizing device 3, the gas after drainage screen primary filter enters photocatalysis intracavity; Because photocatalysis intracavity is provided with nano-titania photocatalyst carrier and quartz burner, the characteristic wavelength of quartz burner is that the light wave of 185nm and 254nm, 254nm directly can kill antibacterial in waste gas and virus; The ultraviolet of 185nm can make oxygen molecule decompose, and produces ozone, and ozone is also the extremely strong material of a kind of oxidisability, can kill the antibacterial in waste gas, virus, the H in simultaneous oxidation waste gas 2s, NH 3deng frowziness gas.Ultraviolet light is when cavity internal radiation, and nano titanium oxide is by under the irradiation of ultraviolet light, and ultraviolet wavelength energy is greater than the forbidden band density of quasiconductor, (namely ultraviolet wavelength is less than 387.5nm), the electronics (e in its valence band -) will be excited on conduction band, in valence band, produce hole (h simultaneously +), photo-induced hole has very strong oxidability, and photogenerated electronics has very strong reducing power, and they can move to the diverse location of semiconductor surface and the hydrone of surface adsorption, oxygen and pollutant generation redox reaction.Photo-induced hole (h simultaneously +) can by OH -be oxidized into hydroxyl radical free radical (-OH), hydroxyl radical free radical has very strong oxidisability, can kill the antibacterial in waste gas, simultaneously can H in oxidation gaseous effluent 2s, NH 3etc. harmful gas.The exhaust-gas treatment of whole photocatalysis intracavity is exactly by hydroxyl radical free radical (-OH), the ultraviolet synergic sterilization deodorization of ozone and 254nm wavelength, thus ensures that exhaust-gas treatment is up to standard.Waste gas behind photocatalysis chamber is cotton by activated carbon filtration again, and its Main Function is protective effect, and when exhaust-gas treatment deodorization is incomplete, active carbon can carry out absorbing and deodorizing as last one barrier.When exhaust air deodorization effect is better, active carbon can adsorb remaining O 3, guarantee waste gas gas outlet O 3concentration meets national standard.
A kind of other structure of the waste gas treatment equipment of ultraviolet catalytic technology that adopts of the present embodiment is see prior art.
