Therefore, spraying, food processing, printed circuit board, semiconductor manufacturing, chemical industry, electronics, leather industry, latex products industry, papermaking and other industries can be selected. The activated carbon adsorption equipment mainly uses porous solid adsorbent activated carbon to have adsorption, it can effectively eliminate organic pollutants and color and taste in industrial waste gas, and is widely used in the end treatment of industrial organic waste gas purification, with good purification effect. After the gas enters the absorption tower through the pipeline, a diffusion process occurs between two different phase interfaces. At the end of the diffusion, the gas is sucked out by the fan and discharged out. adsorption process After the exhaust gas scrubber removes the tiny suspended particles and harmful gases, it enters the adsorption tower and passes through the activated carbon in the tower. Adsorption, removal of harmful components (toluene benzene and other organic gases), in line with the emission standards of purified gas, by the fan exhaust. To the outside.

Overview: Activated carbon adsorption tower is the use of high-performance activated carbon adsorbent solid surface force itself, the adsorption of organic waste gas molecules on the surface of the adsorbent, can benzene, alcohol, ketone, ester, gasoline and other organic solvents of waste gas adsorption, more suitable for large air volume bottom solubility of waste gas treatment, suitable for electronics, chemical industry, light industry, rubber, machinery, ships, automobiles, petroleum and other industries. Activated carbon exhaust gas purification tower is the 1 kind of dry waste gas treatment equipment. The activated carbon adsorption tower consists of a box body and the number of adsorption units filled in the box body, air volume and matching equipment. We can be divided into dry activated carbon adsorption and dry and wet combined adsorption equipment. Activated carbon can choose different fillers to deal with a variety of different waste gas, Mainly includes the 3 categories: 1. Acid waste gas and acid mist (for example: NO2 ,H2SO4,HCL,HF, etc.) 2. Alkaline waste gas (e. g., NH3, etc.) 3. Organic waste gas and odor (for example: benzene, phenols, alcohols, ethers, tinctures) Structure: The main body of the equipment is made of PP, carbon steel or glass fiber reinforced plastic. The internal anti-corrosion treatment is carried out. It has strong acid and alkali resistance and hydrochloric acid corrosion. It is not subject to oxidation and corrosion by other factors under long-term operation and use. The thickness of the main structure can be customized according to the customer and the processing capacity, and it is not strong enough to bear the load required in the structure and operation, and provide the necessary operating platform. The adsorption unit is the core component of the installation of activated carbon adsorption tower. The adsorption unit is installed in a layered drawer type in the equipment box, which can be easily taken out from the inspection doors on both sides. And check that the door is easy to open and tightly sealed. The inspection door of large activated carbon is divided into upper and lower two, which can be opened separately and removed separately. Scope of application: Activated carbon adsorption tower is particularly suitable for low solubility large air volume or high solubility intermittent emission of exhaust gas operating environment.
