3, O
2+, O2+ (M) X, O-(M) X), along with the rising of temperature changes free radical (as: O) into, the utility model utilizes special high energy high ozone UV ultraviolet beam irradiation organic exhaust gas and foul gas, change organic exhaust gas and foul gas as ammonia, trimethylamine, hydrogen sulfide, first sulphur hydrogen, methyl mercaptan, methyl sulfide, methyl disulfide, carbon disulfide and styrene, the VOC class, benzene, toluene, the molecular structure of dimethylbenzene etc., the organic or inorganic macromolecular compound, decomposing airborne oxygen molecule generation free oxygen under the irradiation of high energy ultraviolet beam is active oxygen, so need to combine with oxygen molecule because of positron-electron that free oxygen is taken is uneven, and then generation ozone, ozone has extremely strong oxidation to organic matter, emission molecule open chain or open loop with high molecular polymer or ring shaped molecule structure, resolve into low-molecular weight polymer or micro-molecular gas, plasma by the high voltage low energy consumption carries out the original position ionization reaction again, low-molecular weight polymer or micro-molecular gas that the UV photodissociation is formed thoroughly decompose, and become harmless tasteless little molecule such as CO
2, H
2O etc. discharge by described main gas outlet again, can also utilize the molecular link of bacterium in the high energy UV light beam cracking waste gas, destroy the nucleic acid (DNA) of bacterium, carry out oxidation reaction by ozone again, thoroughly reach the purpose of deodorization and kill bacteria, and its advantage is as follows:
(1) efficiently removes organic exhaust gas and stench: can efficiently remove and major pollutants such as thorough decomposing volatile organic matters (VOCs), inorganic matter, hydrogen sulfide, ammonia, thio-alcohol, and various foul smells, deodorization efficiency can reach more than 95%, can reach innoxious discharging, do not produce secondary pollution, reach the effect of high-effective disinfecting sterilization simultaneously, deodorising effect surpasses country's " odorant pollutant discharge standard " regulation (GB14554-93);
(2) need not to add chemical agent: only need auxiliary the setting to send discharge duct accordingly and send exhaust power, make dusty gas carry out decomposing, purifying, need not to add any material and participate in chemical reaction, do not produce secondary pollution by the utility model, environmentally friendly;
(3) adaptability is strong: can adapt to the deodorization purified treatment of high concentration, atm number, different foul gas materials, but every days 24 continuous throughout the twenty-four hour24, stable and reliable operation;
(4) operating cost is low: the utility model does not have any mechanical action, need not personal management and regular maintenance, only need to make regular check on, the utility model energy consumption is low, 1000 cubic metres of/hour waste gas of every processing, about 0.1 degree of power consumption only, the equipment windage is lower＜300pa, can save and send the exhaust power consumption in a large number;
(5) need not preliminary treatment: foul gas need not to carry out special as heat, preliminary treatment such as humidification, operating ambient temperature is between-30 ℃～95 ℃ Celsius, but humidity equal operate as normal between 40%～98%;
(6) occupation area of equipment is little: be suitable for arranging specific conditions such as compact, that the place is narrow and small, handle 10000m
3/ h exhausted air quantity floor space＜1 square metre.
In sum, the utility model good purification, operating cost is low, energy consumption is low, applied range.Purify applicable to the industrial waste gas deodorizing, waste gas purification as industries such as textile printing and dyeing, plastics, printing, chemical industry, paint of coating, the gas cleaning in kitchens, dining room such as the catering trade such as dining room, hotel, grand hotel, hotel, school, hospital, unit, between sewage treatment plant's grid, the purification of foul gas such as sewage pumping station, aeration tank and sludge drying workshop, the foul gas purification in places such as food factory, slaughterhouse, fermentation plant etc.
The utility model can be widely used in the exhaust-gas treatment field.
