Engineering field for the exhaust-gas treatment of complicated ingredient, has the ability of efficient process complicated ingredient exhaust gas, treated, and gas can
Qualified discharge.
Background technology
Atmosphere pollution is one of China's environmental problem most prominent at present.Wherein industrial waste gas is the important of atmosphere pollution
Source.Most intractable in industrial waste gas is exactly organic exhaust gas, mainly including various hydro carbons, alcohols, aldehydes, acids, ketone and
Amine etc..They are mainly derived from the exhaust gas discharged in oil and chemical industry production process, and feature is that quantity is larger, organic matter
Content fluctuation is big, it is flammable, have certain toxicity, some goes back foul smelling, and the discharge of chlorofluorocarbons can also cause the destruction of ozone layer.
After organic exhaust gas enters human body by respiratory tract and skin, the systems such as human body respiration, blood, liver and organ can be caused temporarily
Property and permanent lesion, especially polycyclic aromatic hydrocarbon type organic can make human body directly carcinogenic.These organic exhaust gas are straight in addition to causing
Outside the atmosphere pollution connect, also secondary pollution can be generated by the reaction of a series of complex under the action of sunshine, become PM2.5
One of main source.So the processing of organic exhaust gas is imperative with purifying.
At present, above-mentioned organic waste-gas purification processing means are mainly included：1) direct high-temperature combustion method；2) catalysis oxidation
Method；3) ozone deodorizing method；4) active carbon adsorption；5) soda acid liquid spray process；6) biological odor removal method etc..These methods are in difference
There are equipment investment is high, operating cost is high, processing is narrow-minded, job insecurity, occupied space is big, is deodorized purification efficiency in degree
It is not high, there are security risk, there are secondary pollution problems.
The present invention is under the conditions of ultraviolet catalytic, the organic matter in gas-vapor mix is carried out Fenton oxidation, so as to real
The processing of existing waste water and gas, the device of invention is a kind of band ultraviolet catalytic gas-vapor mix tower.At present, there are many equipment of type
It can be used to handle exhaust gas or waste water, but few aqueous vapor Integrated Processing Units.As same and Energy Science Co., Ltd is believed in Beijing ten thousand
The absorption adsorption treatment method of the benzene gas containing high concentration of Yin Yedong exploitations, Beijing Wo Taisi environmental protection developments in science and technology Co., Ltd open
The device of the absorption and sorption of hair and bioanalysis combination effect processing exhaust gas.The absorption adsorption treatment method of the benzene gas containing high concentration
It is that high concentration benzene gas is subjected to absorption processing, the gas after absorption carries out condensation process, condensate liquid and condensed gas cycle profit
With the gas after absorption discharges after recycling activated carbon adsorption, this kind of method is suitable only at the gas containing one-component
Reason, then do not apply to the exhaust gas of complicated component.In addition it is widely used absorb processing exhaust device be exhaust gas by spray column or
Bubble tower, exhaust gas is soluble in water to achieve the purpose that handle exhaust gas, and it is soluble easily in water inorganic that this processing method is only suitable only for those
Polluted gas, such as S02.Therefore, lack at present and a kind of equipment is effectively treated for complicated component polluted gas.For above-mentioned
Problem, we devise a kind of aqueous vapor reaction tower, and inorganic pollution soluble easily in water can be removed by absorbing, and be not readily dissolved in water
Organic pollution then using Fenton high-level oxidation technologies carry out ingredient oxidation removal, so as to achieve the purpose that waste gas purification.
A kind of aqueous vapor processing unit that the invention provides is similar to bubble tower shape, but internal structure and exhaust-gas treatment principle have not
Together, which includes water tank, reactive agent, circulating water device, air transporting arrangement, adsorbent equipment.
Invention content
Complicated polluted gas can be effectively treated the purpose of the utility model is to provide a kind of or what aqueous vapor was jointly processed by is
System.

The reactive agent has several layers of water distributing plate, and there are larger spaces for water distributing plate side, and as gas passage, edge has about 5em's high
Water fender under the action of water fender, forms one layer of water layer on water distributing plate, which is absorbed in the organic of water for being catalytically decomposed
Object, water distributing plate plate face are evenly distributed with hole, and aperture about 2mm, under hydraulic pressure and gas pressure, water is sprayed to down by water distribution plate hole
One layer, so as to form spraying layer between two layers of water distributing plate, gas is mixed with the water mist of spraying layer, is urged under ultra violet lamp
Oxidation and absorption process, the circulating water device uses anti-corrosive water pump as power, by water by water tank through corrosion-resistant
Pipeline is pumped into reaction tower top, is sprayed onto in reactive agent by the flusher of tower top, and the air transporting arrangement uses wind turbine
The exhaust gas of collection is blasted into reaction tower bottom, water pump needs to match with power of fan.
A built-in ultraviolet lamp between every two layers of the water distributing plate of reactive agent, ultraviolet lamp is protected with quartz socket tube, ultraviolet
Lamp provides the required light source of catalysis oxidation.
