Principle of Activated Carbon Adsorption Box:
When the exhaust gas is powered by the fan, the negative pressure enters the adsorption chamber and enters the activated carbon adsorption layer. Because of the unbalanced and unsaturated molecular gravity or chemical bonding force on the surface of the activated carbon adsorbent, when the surface of the activated carbon adsorbent contacts with the gas, the gas molecules can be attracted and concentrated on the surface of the activated carbon, which is called adsorption. Using the adsorptive capacity of the surface of activated carbon adsorbent, the exhaust gas is contacted with the porous activated carbon adsorbent on the large surface. The pollutants in the exhaust gas are adsorbed on the surface of activated carbon to separate it from the gas mixture and discharge the purified gas at high altitude. Activated carbon adsorption box is a dry waste gas treatment equipment, which consists of a box and an adsorption unit filled in the box.
Scope of application of activated carbon adsorption tank:
Activated carbon adsorption chamber is mainly used for the treatment of organic waste gas with high air volume and low concentration. Activated carbon adsorbent can treat and purify a variety of organic and inorganic pollutants: benzene, ketones, alcohols, ethers, alkanes and their mixtures, organic exhaust, acid exhaust and alkaline exhaust; it is mainly used in Yao production, smelting, chemical industry, machinery, electronics, electrical appliances, painting, shoemaking, rubber, plastics, printing and environmental desulfurization, deodorization and harmful exhaust gas from various industrial production workshops. Purification treatment.
The structure and composition of the activated carbon adsorption device are as follows:
Activated carbon adsorption purification device, desorption purification device, adsorption fan, desorption fan and other components.
Product characteristics:
Activated carbon is a black powdered, granular or pellet-shaped amorphous carbon with porous structure. The main component is charcoal, which also contains a small amount of oxygen, hydrogen, sulfur, nitrogen and chlorine. It also has the fine structure of graphite, but the grains are small and the layers are irregular. It has a large surface area (500-1000m^3/g). It has strong adsorption capacity and can adsorb gases, liquids or colloidal solids on its surface. The adsorption of gas and liquid can be close to the mass of activated carbon itself.
Equipment composition:
Adsorption equipment is composed of induced draft fan, surface cooler, filter, adsorber, stratified tank, etc. The operation of the whole system is controlled by PLC program, and the adsorber is automatically switched to carry out the operation of adsorption, desorption and drying process alternately.
Functions of activated carbon:
The surface and interior of activated carbon are filled with nano-pore, only about 0.05 nanometer. When harmful chemicals in water flow through activated carbon, van der Waals force is adsorbed by activated carbon micropore, which can effectively adsorb various chemical pollutants in water, such as residual chlorine, organic matter, odor and so on, to achieve the effect of purifying water quality. The larger the sum of specific surface area of surface and internal pore diameter of activated carbon, the stronger the adsorption capacity. The sum of the specific surface area of a gram of activated carbon is about the size of three football fields. In addition, the more mesoporous and porous in activated carbon, the more uniform the distribution, the better the chemical removal rate.
Characteristic:
1. The product has a wide range of adsorptive properties, and has a large capacity. It can adsorb gasoline, aldehydes, phenols, alcohols, olefins and other organic vapors. It has a good adsorbability for inorganic gases (such as No, N, S, S, HF, HCL, etc.) and has a strong oil adsorption capacity. _______
2. Small resistance, fast speed, rapid desorption, army, convenient replacement and waste disposal;
Performance characteristics of activated carbon adsorption device:
The operation process does not produce secondary pollution; the equipment investment is low and the operation cost is low; the performance is stable and can handle many kinds of mixed gases at the same time, and the purification efficiency is more than 95%. The new activated carbon adsorbent has the advantages of low resistance, long life and high purification efficiency. The activated carbon adsorption device can be customized according to the characteristics of waste gas treatment and customer needs. Activated carbon adsorption device is a dry waste gas treatment equipment. The utility model is composed of a box body and an adsorption unit packed in the box body. According to the number of adsorption units and air volume, it can be divided into several specifications. HXT series activated carbon waste gas purifier can treat a variety of different waste gases by choosing different fillers.
