√ Hello, according to the questions you raised, the following is a detailed answer for you: The thermal destruction method The thermal destruction method refers to direct and auxiliary combustion of organic gas, that is, VOC, or using appropriate catalysts Accelerate the chemical reaction of VOC, Z finally reducing the concentration of organic matter, so that it no longer has harmful treatment methods. The thermal destruction method is better for the treatment of organic exhaust gas with lower concentration, so it has been widely used in low -concentration exhaust gas. The adsorption method The adsorption method in organic exhaust gas is mainly suitable for low concentration and high -throughput organic exhaust gas. At this stage, the treatment of this organic exhaust gas is quite mature, the energy consumption is relatively small, but the processing efficiency is very high, and it can completely D -D purify the harmful organic exhaust gas. The oxidation method The oxidation method is toxic, harmful to, and no recycling VOC. The thermal oxidation method is a suitable processing technology and method of Z. Basic principles of oxidation method: VOC and O2 have oxidized reactions, and CO2 and H2O are generated. The oxidation reaction is similar to the chemical combustion process. However, due to the low concentration of VOC, flames visible to the naked eye in chemical reactions will not produce the naked eye. The condensation recycling method At different temperatures, the saturation of organic matter is different. The condensation recycling method is to use the characteristics of organic matter to play a role. Organic substances are extracted through condensation. After the condensation is extracted, the organic exhaust gas can get higher purification. Is to help you this answer!
Organic exhaust gas treatment refers to the treatment, filtering, and purification of organic waste gas generated in the process of industrial production. Usually organic exhaust gas treatment with formaldehyde organic exhaust gas treatment, benzolitzide diopine and other benzene organic waste gas treatment, acetorine organic waste gas treatment, ethyl acetate exhaust gas treatment, oil fog organic exhaust gas treatment, brachycal organic exhaust gas treatment, 苯, acrylic, acrylic acid Organic exhaust gas treatment, resin organic exhaust gas treatment, additive organic exhaust gas treatment, lacquer fog organic exhaust gas treatment, and Tian Na water organic exhaust gas treatment, etc. I. Adsorption method: Use some adsorbent substances such as activated carbon, silicone, zircon molecular sieve, activated aluminum aluminum adsorption and other adsorption of harmful ingredients to eliminate harmful pollution. The advantage of adsorption method is that high efficiency, low energy consumption, mature process, and recycling of post -aid solvents can be recycled. The disadvantage is that the equipment is huge, the process is complex, the operating costs are high after investment, and there are secondary pollution. When there are glue or other impurities in the exhaust gas, the adsorbent is prone to poisoning. Second, the solvent absorption method: use liquid solvent as an absorbent, so that the harmful ingredients in the exhaust gas are absorbed by the liquid, thereby achieving the purpose of purification. As a solvent, the VOC is transferred from the gas phase to the liquid phase, and then the absorption solution is rescued, and the VOC is recycled, and the solvent can be regenerated. Third, thermal destruction method: Thermal destruction method is divided into direct combustion method, catalytic combustion method, and concentrated combustion method. Its damage mechanism is oxidation, thermal cracking and heat decomposition, thereby achieving the purpose of governing VOCS. Fourth, biological treatment method: The purification treatment of biological treatment technology in organic exhaust gas has only begun in recent years, and it is an emerging technology. Common biological treatment processes include biological filtration, biological dripping method, biological washing method, membrane bioreactor, and turntable biological filtration reactor. V. Catalytic oxidation method: The technology of photocatalytic waste gas treatment equipment is a special treatment method that uses special ultraviolet bands (C bands) to break the exhaust molecules and further oxidize and restore it under the action of special catalytic oxidants. The exhaust molecules first pass the special band of high -energy ultraviolet optical wave crushing organic molecules to interrupt their molecular chains. At the same time, through the decomposition of oxygen and water in the air, high -concentration ozone is obtained, and ozone further absorbs energy to form free hydroxyl groups with higher oxidation performance and oxidation. Exhaust molecules. At the same time, a variety of composite inert catalysts are configured according to different exhaust gas components, which greatly improves the speed and efficiency of exhaust gas treatment, thereby achieving the purpose of purifying the waste gas. 6. Features of organic exhaust gas treatment: Organic exhaust gas generally has the characteristics of flammable and explosive, toxic and harmful, insoluble in water, soluble in organic solvents, and difficulty in processing. In the treatment of organic exhaust gas, it is generally adopted by organic waste gas activated carbon adsorption treatment, catalytic combustion method, catalytic oxidation method, acid -base neutral method, and plasma method. It is generally recommended to use plasma, because the low -temperature plasma method has the characteristics of high efficiency and convenient use. The better organic waste gas treatment method is to catalyze the oxidation and purification system. The exhaust gas treatment design is thorough and the layer of purification and filtering the exhaust gas, which is better.
