Organic waste gas is usually flammable, explosive, toxic, insoluble in water, soluble in organic solvents, and difficult to handle. At present, in the organic waste gas treatment process, the most commonly used methods are organic waste gas activated carbon adsorption treatment method, catalytic combustion treatment method, photocatalytic oxidation treatment method, acid-base neutralization method (washing spray method), low-temperature plasma treatment methods and many Different principles and methods.

Plasma treatment technology: adopts double dielectric barrier discharge to generate plasma, the density of plasma generated is 1500 times that of other technologies, and it processes industrial odors, odors, and toxic and harmful gases. The technology is energy-saving, environmentally friendly, and has a wide range of applications. The peculiar smell generated in almost all chemical production links can be treated, and it has a good decomposing effect on dioxin.

Activated carbon adsorption waste gas treatment: The active adsorption device is mainly used to filter and adsorb organic waste gas and dust in the waste gas to achieve the effect of purifying organic waste gas and dust. The adsorption device is a more traditional waste gas treatment method. In the past few years, many companies have used this equipment. At a concentration of 200mg/m3, the waste gas treatment effect is obvious and the treatment cost is the lowest. However, due to the frequent replacement of activated carbon in high-concentration treatment, the cost of consumables and activated carbon after saturation is very high.

Photo-oxygen catalytic waste gas treatment equipment, using special high-energy high-ozone ultraviolet ultraviolet beams, malodorous and malodorous gases such as ammonia and trimethylamine, hydrogen sulfide, hydrogen sulfide and methyl mercaptan, methyl sulfide, dimethyl disulfide, carbon disulfide, carbon disulfide and benzene Ethylene, hydrogen sulfide, volatile organic compounds, molecular chain structure Benzene, toluene, xylene, organic or inorganic polymer molecular chains of odorous compounds, under the high-energy beam of solar ultraviolet rays, degrade into low molecular compounds, such as CO2, H2O, etc. . Use high-energy ultraviolet rays to break the molecular bonds of bacteria in the malodorous gas, destroy the nucleic acid (DNA) of the bacteria, and then oxidize through ozone to completely achieve the purpose of deodorization and sterilization. The purification effect of organic waste gas is very ideal. The input cost and operating cost are relatively low, but the waste gas with a concentration of 300-500mg/m3 or more is not thoroughly treated, and it needs to be combined with other waste gas treatment processes. Especially for the paint industry, because a lot of paint mist will adhere to the lamp tube, which greatly reduces the efficiency of the photooxygen equipment, there must be a curtain cabinet or spray tower in front to deal with the paint mist.

Catalytic combustion is a new technology developed in recent years. It has the advantages of high purification rate, strong adaptability, the lowest energy consumption of combustion, and no secondary pollution. RCO is a new type of catalytic technology, which has the advantages of high RTO energy recovery efficiency and low temperature operation of catalytic reactions. *The catalyst is placed on top of the heat storage material to achieve the best purification effect. The heat recovery rate is as high as 99%. The RCO treatment technology is especially suitable for occasions with high heat recovery requirements. It is also suitable for the same production line, where the exhaust gas composition often changes or The concentration of waste gas fluctuates greatly due to different products. Application industries include coating production lines of manufacturers of automobiles, shipbuilding, motorcycles, bicycles, household appliances, and containers. Petroleum, chemical, rubber, paint, coating, shoe glue, plastic products, tin cans, ink, cables, enameled wire production line waste gas treatment, especially suitable for companies that need heat recovery or drying line waste gas treatment. The drying line can adopt energy recovery to achieve the purpose of energy saving. The types of organic substances that can be treated include benzene, ketones, esters, phenols, aldehydes, alcohols, ethers, hydrocarbons, etc. Although the catalytic combustion method has the best treatment effect at present, its input cost is particularly high. Can not afford.

The odor treatment should be selected according to different gas components. For example, spray water treatment plan should be adopted for dissolving in water, and water spraying method should be adopted for waste gas containing complex components such as hydrogen sulfide and ammonia and dimethyl sulfide waste gas.
