Description
Technical field
The present invention relates to off gas treatment engineer applied field, specifically refer to the manufacture method of a kind of Novel photocatalyst plate.
Background technology
Air is the prerequisite that the mankind depend on for existence and development, and along with the development of industrial production, the factors such as the growth of the size of population, the quantity discharged of waste gas is also increasing year by year. The difference that countries in the world are dropped in industry development degree and environmental protection industry makes air problem present area differentiation, but the continuous consumption along with earth resources, topsoil has become a worldwide difficult problem. Present stage China's topsoil is relatively more serious, and meanwhile, owing to the discharge wantonly of production, life waste gas makes the atmospheric environment of China worsen all the more seriously, China is just being shrouded in topsoil crisis.
In today that industry days reaches increasingly, the discharge kind of waste gas and quantity discharged increase day by day, and composition is also more complicated, often containing the organism being difficult to biological degradation in a large number in waste gas. Topsoil phenomenon becomes a difficult problem urgently to be resolved hurrily, becomes the bottleneck of Chinese society and Economic development. Emission standard and laws and regulations about " three wastes " are also stricter, country has been listed air contaminant treatment in the middle of " 12 " planning in, therefore develops good reliability, research focus that waste gas processing method that processing efficiency is high has become environmental protection industry (epi).
In waste gas is formed, foul gas and volatile organic compounds (VOC) occupy very big proportion, wherein foul gas mainly comprises hydrogen sulfide, ammonia, mercaptan and dimethyl sulphide etc., and volatile organic compounds mainly comprises benzene, toluene, dimethylbenzene, formaldehyde, hexane, heptane, methyl ethyl ketone, acetone, tetracol phenixin, vinyl acetic monomer etc. These gases, if effectively do not processed, to the quality of life of atmospheric environment, the mankind and healthy will cause very big harm.
Traditional waste gas treatment process mainly comprises the combination process of physics method, chemical method, biological process and these three kinds of methods. Common physical method has electrostatic trapping, washing, absorption and sorption, condensation etc., and these methods have been widely used in off gas treatment field, and often kind of method all has its feature and the scope of application. Common chemical process has burning, catalyticcombustion etc., the organic exhaust gas that these methods are applicable to the big air quantity of process usually, volatile organic content is high. Also develop some biological treatment technology for waste gas both at home and abroad in recent years: such as biological process, membrane separation process etc., the current sewage plant waste gas pollution control and treatment at home of this method has a small amount of utilization, little for the utilization administered in industrial gaseous waste. The waste gas complicated for character, processing requirements is high, often to be taked the combination process of above three kinds of methods, waste gas could carry out the process of economical and effective.
But industrial much waste gas contains more than one pollutents, and pollutent character complexity, concentration height, processing requirements are sternly, now adopt traditional waste gas treatment process to be just difficult to reach process object cost-effectively.Therefore, need the exhaust gas treatment technology of development of new, and UV photodissociation catalytic oxidation is a kind of novel exhaust gas treatment technology being developed in recent years, its principle is in photocatalyst cleaner, high energy ultraviolet beam and air, the ozone that TiO2 reaction produces, stench organic gas is carried out collaborative decomposition oxidizing reaction by OH (hydroxyl radical free radical), macromole organic gas makes its chain structure rupture under action of ultraviolet radiation simultaneously, stench organic gas material is made to be converted into low molecular compound or the complete oxidation of odorless, generate water and CO2, whole decomposition oxidising process completed in 1 second, photocatalytic method only needs consuming electric power, stench organic gas is carried out Synergistic degradation reaction by high energy ultraviolet beam and air, the ozone of TiO2 reaction generation, OH (hydroxyl radical free radical) in tower, can be discharged in air after being effectively decomposed into CO2 and H2O, both qualified discharge, also eliminates the stench of gas.
The process of foul gas and VOC waste gas is had following several big advantage by UV photocatalytic method:
(1) efficiently except stench: can efficiently remove the principal pollutant such as volatile organic matter (VOC), inorganics, hydrogen sulfide, ammonia, thio-alcohol, and various stench taste, deodorization efficiency can reach more than 95%, and deodorising effect reaches odorant pollutant discharge primary standard (GB14554-93) of country's promulgation.
(2) without the need to adding any material: only need to arrange corresponding air draft pipeline and air draft power, make pending gas carry out oxygenolysis purification by this equipment, it is not necessary to add any material and participate in chemical reaction.
(3) strong adaptability: high density can be adapted to, atm number, the deodorization purifying treatment of different foul gas material, can every day 24 continuous throughout the twenty-four hour24, stable and reliable operation.
(4) running cost is low: this equipment, without the action of any machinery, without noise, it is not necessary to personal management and routine maintenance, only need to be made regular check on, and this equipment energy consumption is low, and the extremely low < 700pa of equipment windage, can save a large amount of air draft power consumption.
(5) applied widely: photochemical catalysis is applicable to that refinery, rubber plant, tannery, printing house, chemical plant, pharmaceutical factory, metal foundry, plastic reclaimed factory, spraying solvent etc. be organic and the deodorization purifying treatment of inorganics foul gas; Spray paint (painting) workshop, chemical industry, medicine, rubber, food, printing and dyeing, papermaking, the production process such as brewage in the toxic harmful exhaust gas that produces also can use photocatalysis treatment.
The core technology of UV photochemical catalysis is research and development and the application of the parts such as UV and photocatalyst, during operation, the UV photophore of device interior needs to act synergistically with built in light catalyst plate, waste gas through equipment body is carried out catalytic oxidation treatment, so needing a kind of Novel photocatalyst plate that can carry out well acting synergistically with UV photophore.
