| Introduction of several kinds of organic waste gas treatment methods and advantages and disadvantages of Zhejiang Austrian Xin Technology Co., Ltd. |
| 1, thermal combustion method The organic waste gas and fuel gas are fully mixed in the high temperature, and the complete combustion is realized. Suitable for the treatment of high concentration, small amount of combustible gas, high purification efficiency, organic waste gas is completely oxidized and decomposed, shortcomings: equipment is easy to corrosion, high cost, easy to form two pollution; 2, catalytic combustion method Under the action of the catalyst, the hydrocarbon in the organic waste gas is oxidized into water and carbon dioxide under the condition of low temperature, and the purpose of the treatment is achieved. Disadvantages: catalyst poisoning, high cost of investment; 3, absorption method The use of organic waste gas is easy to dissolve in water, and the waste gas is directly contacted with water, so that it can be dissolved in water to achieve the effect of removing waste gas. Suitable for water-soluble, organic gases, emission source has the advantages of simple process, convenient management, low operation cost, equipment faults, have two pollution, should be disposed of the washing liquid; low purification efficiency; 4, adsorption method The adsorbent is used to adsorb organic waste gas, and is suitable for treating low concentration organic waste gas. Purification efficiency is high, the cost is low. Disadvantages: regeneration is more difficult, need to constantly change; 5, biological method The use of microbial life process of the waste gas in the decomposition of gaseous pollutants into less or even harmless substances. In nature, there are a variety of microorganisms, almost all of the inorganic and organic pollutants can be transformed. Biological treatment does not need regeneration and other advanced treatment process, compared with other purification methods, it has the advantages of simple equipment, low energy consumption, safe and reliable, no two pollution, etc., but can not be recycled. 6, low temperature plasma technology In the process of dielectric barrier discharge, the plasma generated in the plasma contains very high chemical activity particles, such as electrons, ions, free radicals and excited molecules. The pollutants in the waste gas react with the active groups with high energy, and eventually convert to CO2 and H2O, so as to achieve the purpose of purifying the waste gas. Wide application range, high purification efficiency, especially suitable for other methods difficult to deal with the multi - component odor gases, such as chemical industry, medicine and other industries. Electronic energy is high, almost all of the stench of gas molecules, low operating costs; quick response, equipment start, stop very quickly, with the use of. Disadvantages: one-time investment is higher, security risks. 7, photocatalytic oxidation Photocatalytic oxidation treatment technology is the use of special ultraviolet band (C band), in the role of special catalytic oxidants, the exhaust gas molecules are broken and further oxidation reduction of a special treatment. The exhaust gas molecules go through special band high-energy ultraviolet light wave breaking organic molecules, the breaking of the molecular chain; at the same time, through the decomposition of oxygen and water in the air, high concentrations of ozone, ozone to absorb energy, the formation of oxidation of higher free hydroxyl groups, oxidation gas molecules. At the same time, according to different exhaust gas composition of a variety of compound inert catalyst, greatly improve the speed and efficiency of the treatment of waste gas, so as to achieve the purpose of purification of waste gas. Found no faults. |
