Activated Adsorption Carbon Filter Stainless Steel Odour Suppression Systems

Waste Gas Treatment Equipment: Activated carbon adsorption filtration equipment

(1) Equipment Overview

Activated carbon adsorption and filtration equipment is often used for gas adsorption, separation and purification, solvent recovery, decolorization agent for sugar solution, oil, glycerin, medicine, deodorant for drinking water or refrigerator, filter for gas mask, and can also be used as catalyst or metal salt catalyst cross section.

(2) Product technical principle

When the exhaust gas is powered by the fan and enters the adsorption box, it enters the activated carbon adsorption layer. Since there is unbalanced and unsaturated molecular attraction or chemical bonding force on the activated carbon adsorption surface, when the surface of the activated carbon adsorbent comes into contact with the gas, it can attract Gas molecules concentrate and remain on a solid surface, a phenomenon called adsorption. The adsorption capacity of the activated carbon adsorbent surface is used to bring the exhaust gas into contact with the large-surface porous activated carbon adsorbent. The pollutants in the exhaust gas are adsorbed on the surface of the activated carbon, separating them from the gas mixture, and the purified gas is discharged at high altitude.

(3) Process flow

Activated carbon is a kind of black powdery, granular or pellet-shaped amorphous porous carbon. The main component is carbon, and also contains a small amount of oxygen, hydrogen, sulfur, nitrogen, and chlorine. It also has a fine structure like graphite, but the grains are smaller and the layers are irregularly stacked. Has a large surface area (500~1000㎡/g). It has strong adsorption capacity and can adsorb gas, liquid or colloidal solid on its surface. The adsorption of gas and liquid can be close to the quality of activated carbon itself.

Its adsorption is selective, and non-polar substances are easier to adsorb than polar substances. In the same series of substances, substances with higher boiling points are more likely to be adsorbed. The greater the pressure, the lower the temperature, the higher the concentration, the greater the adsorption capacity. On the contrary, reducing pressure and increasing temperature are beneficial to the desorption of gases.

Activated carbon is often used for gas adsorption, separation and purification, solvent recovery, decolorizing agent for sugar liquid, grease, glycerin and drugs, deodorant for drinking water or refrigerator, filter agent for gas masks, and can also be used as a catalyst or metal salt. Catalyst cutoff.

(4) Scope of application

Activated carbon adsorption technology is widely used in low concentration and large air volume in petroleum, chemical, rubber, painting, printing, electronics, pharmaceuticals, textile printing and dyeing, food, furniture, coating, plastics, feed, leather, machinery, semiconductor manufacturing, material synthesis and other industries. exhaust gas treatment.
