Embodiment 1
Fig. 1 is refer to, the present embodiment provides a kind of fermentation waste gas processing equipment 100, including inlet duct 110, dehumidifying dress
120, light processor 130 and exhaust apparatus 140 are put, inlet duct 110 is connected by first passage 101 with dehydrating unit 120,
Dehydrating unit 120 is connected by second channel 103 with light processor 130, light processor 130 by third channel 105 with
Exhaust apparatus 140 connects.Fermentation waste gas processing equipment 100 is according to design outline and size is actually needed, in the present embodiment, such as
Fig. 1, fermentation waste gas processing equipment 100 are pyramidal structure.
Dehydrating unit 120 is used to remove the steam in discarding, and reduces the relative humidity of waste gas.In the present embodiment, remove
Wet device 120 includes dehumidifier 121.Discarding for typically discharging has certain heat, and dehydrating unit 120 has resistance to elevated temperatures,
Can normally it be dehumidified below 60 DEG C.In the present embodiment, dehumidifier 121 includes heat exchanger (not shown), compressor (figure
Do not show), heat exchanger uses inner screw thread copper pipe, and fin uses titanium aluminium, and refrigerant is reconciled using the anti-high pressure of mixed type and formed.
Dehumidifier 121 also includes display, for displays temperature and humidity.Because fermentation waste gas has corrosivity, dehydrating unit 120 has
There is anti-corrosion function.Heat exchanger is made using stainless steel plate, and electric cabinet is using the closed electronic box processing of silica gel, and refrigeration accessory is by anti-
Corruption processing, water accumulating disc are made of stainless steel.
In the present invention, dehydrating unit 120 cooperates with light processor 130 and fermentation waste gas is handled, and works as warp
The relative humidity for crossing the fermentation waste gas of the processing of dehydrating unit 120 is 30~80%, and the effect of light processor 130 is more preferable, fermentation
The degradation rate of waste gas is higher, the gas environmental sound of discharge.
The present invention is handled fermentation waste gas by the way of photodissociation composite photocatalyst, and the processing mode works well.
Light processor 130 includes body 131, the ultraviolet light source 133 for photodissociation fermentation waste gas and for degradable fermented waste gas
Filter screen 135, ultraviolet light source 133, filter screen 135 are arranged in body 131.
In the present embodiment, ultraviolet light source 133 is high energy quartz UV ultraviolet light sources 133.Ultraviolet light source 133 produces
Electromagnetic wavelength light beam, it can make odorant molecular dissociation under the bombardment of light quantum largely taking and distribute.In the present embodiment, it is purple
The wavelength of outer line source 133 is 150nm~250nm, is 185nm, 195nm, 200nm, 225nm preferably.
Oxygen and moisture in light processor 130 can produce largely in the presence of the light quantum of ultraviolet light source 133
Hydrogen in statu nascendi, reactive hydrogen and hydroxyl oxygen isoreactivity group, a part of fermentation waste gas and active group react, and is converted into titanium dioxide
The innocuous substance such as carbon and water, discarded purpose is removed so as to reach.
Meanwhile the oxygen molecule that ultraviolet beam can be decomposed in air produces free oxygen, i.e. active oxygen, free oxygen and oxygen molecule
With reference to generation ozone.Ozone has extremely strong oxygenolysis to organic matter due to its strong oxidizing property, make fermentation waste gas and
Stench Degradation and Transformation is into low molecular compound, water and carbon dioxide.Due to the unstability of ozone, ozone and the organic fermentation of stench
After waste gas effect, itself is faded away, and final discharge will not be had an impact under conditions of substantial equilibrium.
In order to increase the sphere of action of ultraviolet light source 133, in the present embodiment, the fluorescent tube of ultraviolet light source 133 is spiral shell
Coil.
In the present embodiment, the photochemical catalyst of filter screen 135 is nano-scale anatase titanium dioxide.Received when ultraviolet lighting is mapped to
When on rice titanium dioxide granule, electronics is excited by ultraviolet light, transits to conduction band and forms free electron, and a band is formed in valence band
The hole of positive electricity, form electron-hole pair.Utilize the oxidation in caused hole and the reducing power of free electron, titanium dioxide
Titanium and hydrone, the oxygen molecule of surface contact react, and produce the extremely strong free radical of oxidizing force.Free radical decomposing and fermenting waste gas
In organic substance, the hydrogen in organic substance and carbon are resolved into water and carbon dioxide.
Specifically, the matrix of filter screen 135 is made by nickel foam, nano titanium oxide is loaded with matrix.Using bubble
Foam nickel, due to its existing metallic nickel high temperature resistant, feature corrosion-resistant, chemical property is stable, has foam unique again as matrix
Tridimensional network.On the one hand the structure can increase the contact area of titanium dioxide and fermentation waste gas, improve photocatalysis effect
Rate, improve the degradation efficiency to fermentation waste gas.Preferably, the porosity of filter screen 135 is more than 95%, has filter screen 135 good
Gas circulation and permeability, there is preferable photocatalysis efficiency.
