Example 1
The present embodiment provides a deodorizing device, which is structurally shown in fig. 1, and has a box 400 with two open ends, and an air duct assembly 100, a wind power assembly 200 and a reaction assembly 300 are disposed in the box 400. The air duct assembly 100 includes a hollow duct 101, an air inlet 101a and an air outlet 101b are provided at two ends of the duct 101, and are fixedly disposed in the box 400 through a bracket 401, and the air inlet 101a is connected with an air vent of the garbage fermentation device. The wind power assembly 200 is connected with the air duct assembly 100 to generate negative pressure, so as to drive the air in the pipeline 101 to flow from the air inlet 101a to the air outlet 101b, so that the waste gas in the garbage fermentation device passes through the pipeline 101. The reaction unit 300 includes a photocatalyst disposed in the duct 101, and a light source part 301 disposed outside the duct 101, and the light source part 301 irradiates ultraviolet light to the photocatalyst. When the waste gas passes through the pipeline 101, the malodorous substances in the waste gas are decomposed into low molecular substances, water and carbon dioxide under the action of the photocatalyst and ultraviolet light, so that the waste gas deodorization treatment of garbage fermentation is realized.
The photocatalyst in this example is titanium dioxide (TiO)2) And is coated on the inner wall of the pipeline 101. The duct 101 is made of transparent material, so that ultraviolet light emitted by the light source component 301 can penetrate through the wall of the duct 101 to irradiate on titanium dioxide in the duct 101, a light-contact catalytic reaction is generated, hydroxyl is generated through excitation, ozone is generated, and a lot of malodorous substances can be oxidized quickly. In addition, after the ozone obtains the energy of the composite ion photons, the ozone can be decomposed very quickly to generate hydroxyl free radicals with stronger oxidizing capability, and a series of processes of synergistic and chain reaction can be completed with malodorous gas in a very short time. The energy fusion of ultraviolet light waves is greatly promoted and enhanced, more active oxygen and ozone are generated through catalysis while waste gas and odor molecules are efficiently cracked at higher energy, and the waste gas and odor are subjected to more thorough catalytic oxidation decomposition reaction, so that the waste gas and odor are degraded and converted into low molecular compounds, water molecules and carbon dioxide, and the aims of deodorizing and killing bacteria are fulfilled.
Preferably, the ultraviolet light in the present embodiment is vacuum ultraviolet light (UVD) with a wavelength of 185 nm. The photon energy of 185nm ultraviolet light is 647kJ/mol, which is larger than the molecular covalent bond energy of most organic waste gas gases, so that the covalent bonds of most organic waste gas molecules can be directly broken, and the molecular chain breakage is caused. The pipe 101 associated therewith uses quartz glass as the pipe wall material. The quartz glass has no absorption band for the ultraviolet light in the range of 185-250nm wave band, and can ensure the 185nm vacuum ultraviolet light perforated pipe wall. By arranging quartz glass as the tube wall material, the light source part 301 of ultraviolet light can be arranged outside the tube 101, thereby avoiding direct contact between the light source part 301 and gas and facilitating maintenance of the light source part 301.
Ultraviolet light irradiates the gas to directly crack odor molecules in the gas, the reaction process is as follows,
R+hv(185nm)→R1+R2
simultaneously, 185nm ultraviolet photons irradiate oxygen molecules to uniformly crack oxygen covalent bonds into oxygen atoms, and the oxygen atoms are also connected with surrounding oxygen molecules O2Combine to form ozone O containing 3 oxygen atoms3。
The reaction process is as follows:
O2+hv(185nm)→O+O
O+O2→O3
3O2+hv(185nm)→2O3
ozone has strong oxidation function, can directly oxidize and decompose part of organic waste gas, and has the following reaction process,
R+O3→Rn+RM→…→CO2+H2O+O2
R+O·→Rn+RM→…→CO2+H2O
R+O3→R1+R2+O2
when photons with energy higher than the forbidden band width of the semiconductor irradiate the semiconductor, valence band electrons of the semiconductor undergo band-to-band transition, and transition from the valence band to the conduction band, thereby generating positively charged photogenerated holes and negatively charged photogenerated electrons. The strong oxidizing power of the photogenerated holes and the reducing power of the photogenerated electrons cause the semiconductor photocatalyst to initiate a series of photocatalytic reactions.
Namely when titanium dioxide (TiO)2) When the semiconductor particles are brought into contact with water, hydroxyl groups are generated at a high density on the semiconductor surface. Since the oxidation potential of the hydroxyl group is above the valence band position of the semiconductor,and is a species with high density on the surface, therefore, the holes generated on the surface of the semiconductor by light irradiation are firstly captured by the surface hydroxyl to generate hydroxyl free radicals with strong oxidizing property, the reaction process is as follows,
TiO2+hv→e-+TiO2(h+)
TiO2(h+)+H2O→TiO2+H++·OH
TiO2(h+)+OH-→TiO2+·OH
the hydroxyl radical (. OH) induces a series of radical chain reactions, oxidatively decomposing all organic species, and finally degrading them to CO2、H2O and trace inorganic salts. The chemical reaction participated by hydroxyl free radical (. OH) belongs to free radical reaction, the chemical reaction speed is very fast, and the reaction time is less than 1 s. Meanwhile, hydroxyl free radical (. OH) can kill various microorganisms, and the reaction process is as follows,
R+·OH→RoX→Rn+RM→…→CO2+H2O
the exhaust gas molecules are cracked under the irradiation of ultraviolet light, the oxygen molecules are converted into ozone molecules, and the ozone molecules participate in the oxidative decomposition of the exhaust gas molecules. In addition, under the action of photocatalysis, hydroxyl free radicals are generated for decomposition and disinfection. Under the action of multiple oxidative decomposition, the exhaust gas molecules are thoroughly decomposed into harmless CO2、H2O and other small molecules, and realizes the harmless treatment of the waste gas.
Alternatively, the titania photocatalyst of this embodiment may be doped in quartz glass to form the pipe 101.
