Waste gas is irradiated using special high energy high ozone UV ultraviolet beams, cracking industrial waste gas is such as:Ammonia, trimethylamine, sulphur Change hydrogen, first sulphur hydrogen, methyl mercaptan, methyl sulfide, butyl acetate, ethyl acetate, methyl disulfide, carbon disulfide and styrene, sulfide H2S, VOC class, the molecular chain structure of benzene,toluene,xylene make organic or inorganic macromolecule malodorous compound strand, in height Under energy ultraviolet beam irradiation, degraded is transformed into low molecular compound, such as CO2, H2O.Utilize high energy high ozone UV ultraviolets The oxygen molecule that light beam is decomposed in air produces free oxygen, i.e. active oxygen, because free oxygen takes positron-electron imbalance so need to be with Oxygen molecule is combined, and then produces ozone.UV+O2 → O-+O* (active oxygen) O+O2 → O3 (ozone), it is commonly known that ozone is to having Machine thing has extremely strong oxidation, has the elimination effect got instant result to industrial waste gas and other excitant peculiar smell.Industry Waste Gas is input to after this cleaning equipment using exhaust equipment, and cleaning equipment is with high energy UV ultraviolet beams and ozone to industrial waste gas Carry out collaboration and decompose oxidation reaction, make its Degradation and Transformation of industrial waste gas material into low molecular compound, water and carbon dioxide, then lead to Cross exhaust duct discharge outdoor.The molecular link of bacterium in industrial waste gas is cracked using high energy UV light beams, the nucleic acid of bacterium is destroyed (DNA) oxidation reaction, then by ozone is carried out, thoroughly reaches that the purpose of purification and killing bacterium considers from purification air efficiency, We have selected-C-band ultraviolet and ozone, put with reference to the higher makeup of corona current and adsorption technology is put using impulse electric corona mutually tied The principle of conjunction is eliminated to pernicious gas, wherein-C-band ultraviolet is mainly used to remove hydrogen sulfide, ammonia, benzene, toluene, diformazan Benzene, formaldehyde, ethyl acetate, ethane, acetone, urethane, resin, etc. gas decomposition and fission, organic matter is changed into inorganic chemical Thing.
Lacquer spraying waste gas three major issues:Coating cloud, dust, organic exhaust gas, peculiar smell!
Waste gas produced by painting workshop mainly includes coating cloud and organic exhaust gas.Coating cloud --- paint mists in high pressure effect Particulate is melted into, but car body surface can not be all arrived in spraying, this part paint particle is with air-flow disperse into coating cloud;Organic waste Gas --- the volatilization of solvent and diluent in paint vehicle, organic solvent will not be attached to object being painted surface with paint, spray painting and All release is formed organic exhaust gas (VOC) by solidification process.Therefore the coating cloud drop of a large amount of liquid is not only contained in lacquer spraying waste gas, Also contain gaseous volatile organic waste gas composition (VOC).
Understand that workshop is now alkyd paint with spray painting by Field Research.Alkyd paint mainly by alkyd resin, No. 200 it is molten Agent gasoline is constituted, addition pigment, solvent, anti skinning agent, the composition such as drier (the lead zinc of manganese containing cobalt calcium).Therefore, in this project Waste gas major pollutants are:Coating cloud, dust, organic exhaust gas (esters, benzene,toluene,xylene).
In photochemical catalytic oxidation technique by ultraviolet light on nano-photocatalyst, electron-hole pair is produced, with surface Moisture (H2O) and oxygen (O2) effect of absorption, generation oxidisability extremely strong hydroxyl radical free radical (OH-), H2O2, ozone O3 etc., Such as pollution components redox such as esters, benzene class, Ammonia of various volatile organic waste gas into carbon dioxide (CO2) and water (H2O), so as to reach the purpose for administering waste gas.
1.2 photocatalysis principle
From specific photochemical catalyst TiO2, catalytic action is produced under the high energy UV ultraviolet irradiations of specific wavelength, The hydrone and air of surrounding is set to excite the great active OH free radicals of generation, H2O2, ozone O3 etc..These radical oxidation energy Power is very strong, volatile organic matter strand in energy pyrolysis oxidization lacquer spraying waste gas, changes the structure of matter, by macromolecule polluter Crack, be oxidized to low molecule innocuous substance, its removal efficiency can 99%.
Ozone is a kind of strong oxidizer, is also universally acknowledged spectrum efficient sterilization disinfectant.Ozone is more than oxygen molecule One active oxygen atom, chemical property is especially active.Its powerful oxidisability, both can be with oxidation Decomposition organic matter, can also Inorganic matter is decomposed, main foul smell ammonia, trimethylamine, toluene, dimethylbenzene, methyl mercaptan, methyl sulfide, carbon disulfide, styrene all may be used To crack.In the presence of ozone, these organic pollutions are broken down into small-molecule substance by macromolecular substances, have without any Poison residual, will not form secondary pollution, be described as " oxidant and disinfectant that most clean ".
Process characteristic
1st, oxidisability is strong, efficiently except stench:TiO2 photodissociation oxidation equipment can efficiently remove volatile organic matter (VOC), the major pollutants such as inorganic matter, hydrogen sulfide, ammonia, thio-alcohol, and various foul smells, deodorising effect substantially exceed state (GB14554-93) emission standard for odor pollutants that family promulgates for 1993.Nine major classes, 114 kinds of pollutions that Environmental Protection Agency announces Thing is proved to be governed by photodissociation catalysis oxidation, even if to atom organic matter such as halogenated hydrocarbons, fuel, nitrogenous organic Thing, organophosphorus insecticide also have good removal effect.
2nd, any chemical substance need not be added:Only need to set corresponding exhaust duct and air draft power, make foul gas Deodorization decomposing, purifying is carried out by this equipment, chemical reaction is participated in without adding any chemical substance.
3rd, it is applied widely:It is suitable for high and low concentration, atm number, the deodorization purified treatment of different foul gas materials can Run at normal temperatures, can daily 24 continuous throughout the twenty-four hour24, stable and reliable operation.
4th, operating cost is low:Equipment is noiseless without any mechanical action, without personal management and regular maintenance, only needs to make Inspect periodically.
5th, long lifespan:The life-span of photochemical catalyst is endless in theory, without changing.
Green energy resource:Photochemical catalyst is activated using luminous energy, the progress of oxidation reaction is driven, meets the think of of energy-saving and emission-reduction Think.
The cardinal principle of ion deodorization equipment is under high voltage electric field effect, substantial amounts of positive and negative oxonium ion to be produced, with very Strong oxidisability.The foul smell factor can be polluted in extremely short time internal oxidition, decomposition methyl mercaptan, ammonia, hydrogen sulfide, ethers, amine etc., The chemical bond of volatile organic compoundses is opened, carbon dioxide and water etc. is ultimately generated and stablizes harmless small molecule, so as to reach net Change the purpose of air.
Low temperature plasma is the state of material the 4th after solid-state, liquid, gaseous state, when applied voltage reach gas When thermoelectricity is pressed, gas is breakdown, produces the mixture including electronics, various ions, atom and free radical.In discharge process Although electron temperature is very high, heavy particle temperature is very low, and low-temperature condition is presented in whole system, so referred to as low temperature plasma. Low-temperature plasma degradation pollutant is to utilize the pollutant in these high energy electrons, free radical isoreactivity particle and waste gas to make With, contaminant molecule is decomposed within the extremely short time, and the follow-up various reactions of generation are eventually converted into CO2 and H2O, To reach the purpose of degradation of contaminant.
During cold plasma discharge, electronics obtains energy from electric field, and energy is converted into pollutant by colliding The interior energy or kinetic energy of molecule, these molecules ionization that are excited or occur for obtaining energy form active group, while in air Oxygen and moisture can also produce substantial amounts of hydrogen in statu nascendi, active oxygen and hydroxyl oxygen isoreactivity group in the presence of high energy electron, The mutual collision rift of these active groups has just triggered the physics of a series of complex, chemical reaction.From the active group of plasma Composition is as can be seen that be rich in high chemically active particle inside plasma, such as electronics, ion, free radical and excitation state are divided Son etc..Polluter in waste gas with these there is the active group of higher-energy to react, and be eventually converted into CO2 and H2O Deng material, so as to reach the purpose of purification waste gas.
