Abstract
The utility model provides a photochemical degradation device for organic exhausts, which solely makes use of ozone, UV rays or ozone plus UV rays to oxidize organic exhausts. First, filter out such substances as the particles in the exhausts to be treated. After being initially purified, the exhausts enter UV ray-ozone reaction zone. In the area of UV ray, ozone exhaust exists, and the exhaust is radiated in the UV-ozone zone and reacts with the ozone. Then after being completely purified by the solvent absorbent device and regulated in discharge airflow, the exhaust is discharged from the discharge outlet. The device realizes the highly efficient, safe and harmless exhaust degradation of such organic substances as 'Tripbenzene' and provides an economic, highly efficient and pollution-free treatment way for polluting exhausts. The device can be applied in the treatment of such polluting fumes as 'Tripbenzene' in shoe-making industry and can also be used in the treatment of other polluting exhausts discharged by other factories and enterprises.
Description
Technical field:
The utility model belongs to the technical field of utilizing the photo chemistry technology degradation of organic gas, particularly a kind of device that utilizes ultraviolet ray and ozone treatment organic gas.
Background technology:
Chemical industry, coating, printing, the volatile organic matter that produces in the industrial production such as shoemaking has caused that people more and more pay close attention to, benzene particularly, toluene, harmful steam of dimethylbenzene all is volatile organic solvent, be the environmental contaminants that a class has a strong impact on human health, vaporized gas mainly enters human body through respiratory tract, after people suck the air that is polluted by " triphen ", to cause urgency, slow poisoning, show as sphagitis, leucocyte reduces, alpastic anemia etc., to hemopoietic system, nervous system, cardiovascular and cerebrovascular and embryo have great infringement, its toxicity size is followed successively by benzene＞toluene＞dimethylbenzene, and the toxicity of triphen mist is bigger.Triphen " be one of main air pollutants in city, wherein, the concentration of toluene is higher relatively in urban air.Some developed countries make laws, and the discharging of strict these gaseous contaminants of control requires to take certain control measures.
The improvement method that domestic at present waste gas such as " triphens " mainly adopts comprises solvent absorption, ADSORPTION IN A FIXED BED method, Production by Catalytic Combustion Process, absorption/desorption-Production by Catalytic Combustion Process and photochemical method etc.
Solvent absorption is to utilize " structural similarity mixes " principle,, it is absorbed during by the absorption tower at waste gas as lyosoption with not volatile organic solvent under No. 0 normal temperature such as diesel oil, and efficient can reach more than 93%, but the waste gas qualified discharge after the absorption.This method is simple and easy to do, and cost is not high, but has the difficult shortcoming of post processing of the solvent diesel oil that has absorbed a large amount of polluters, does not tackle the problem at its root.
The ADSORPTION IN A FIXED BED method is to utilize organic molecule is had the solid matters such as active carbon, diatomite, organobentonite of strong adsorption capacity as sorbing material, arrange in some way, fix, form adsorbent bed, when waste gas under certain flow velocity and the temperature from wherein by the time, promptly be adsorbed.It is more difficult that the problem of this method also is to have adsorbed the active carbon of pollutant, and may cause secondary pollution.In addition because also there is security hidden trouble in the inflammable and explosive property of organic matter and active carbon.
The Production by Catalytic Combustion Process utilization contains the form formation catalytic combustor of the carriers such as ceramic honey comb of catalyst with fixed adsorption bed, earlier the combustion chamber is preheating to 300 ℃, then waste gas is fed, and can reach the effect that catalytic combustion is removed organic exhaust gas.If " triphen " concentration is more than 2000ppm in the waste gas, the heat that its burning produces promptly is enough to keep the temperature of combustion chamber, in addition consumed energy.But " triphen " concentration in fact most of industrial waste gases is all below 1000ppm, exists with Production by Catalytic Combustion Process and needs that consumes energy keeps that the temperature of combustion chamber, cost are higher, the easy shortcoming such as poisoning of catalyst.
Absorption/desorption-Production by Catalytic Combustion Process combines the ADSORPTION IN A FIXED BED method with Production by Catalytic Combustion Process.Its basic structural unit is divided into absorption/desorption chamber and two parts of catalytic combustor substantially.Show that according to the current paper data at present adsorption effect is best surely belongs to NACF, it has specific area (can reach 2000m greatly
2/ g), adsorption capacity height (be granular activated carbon several times～tens times), adsorption rate fast (than fast 2～3 orders of magnitude of granular activated carbon), advantage such as easy to use; be the new material that replaces traditional activated carbon granule, to begin to be applied to the improvement of various organic exhaust gas.When the waste gas of low concentration passes through, carbon fiber adsorption and catalytic combustion in the bed is fixed earlier, when reaching certain adsorbance, the hot blast that feeds 120 ℃ makes pollutant desorption (reversible reaction), at this moment waste gas concentrates through absorption, concentration improves greatly, and entering the heat that catalytic combustor rear oxidation burning produced is enough to keep the temperature of combustion chamber; Also can utilize the hot air circulate of discharge to carry out desorption simultaneously, save the energy greatly.Plural construction unit is arranged in whole system, take turns to operate at a certain time interval, can handle waste gas continuously, efficiently.Shortcoming is bigger equipment investment and higher operating cost, and cost is higher; The equipment complex structure; Easily spontaneous combustion, poor stability.
The photochemical oxidation technology is the advanced technology that grows up in the last thirty years in the world, have the incomparable advantages of conventional art such as high efficiency under normal temperature, the normal pressure, broad spectrum activity, long-life, big flow, non-secondary pollution with it, thereby have very large potential using value, become ten minutes active research direction in waste gas, the wastewater treating technology.Obtain development at full speed especially in the nearly more than ten years, progressively obtained actual application in western countries at present, and replaced chlorine (bleaching powder) and simple traditional environmental contaminants degradation techniques such as ozone oxidation in many environmental protection field gradually.Developed country has been applied to the photochemical oxidation technology urban industry wastewater organic pollutant degradation treatment, has also carried out a large amount of research aspect the improvement of waste gas, has obtained positive achievement.
Utilize photochemical basic principle, the new method of research, development process all contaminations and new technology are to pollute the focus of control chemical research always, Chinese scholars has been done a large amount of basic works in this field, obtain many achievements, progressively formed the photochemical method that pollutes control.
