The Adsorption Process: Due to the presence of unbalanced and unsaturated molecular attractions or chemical bond forces on the solid surface, when this solid surface comes into contact with a gas, it can attract gas molecules, causing them to concentrate and remain on the solid surface. This phenomenon is known as adsorption. By utilizing the adsorption capacity of the solid surface, the waste gas is brought into contact with a porous solid material with a large surface area. The pollutants in the waste gas are adsorbed onto the solid surface, thereby separating them from the gas mixture, achieving the goal of purification.

Activated Carbon Introduction: Activated carbon is an amorphous, black, powdered, granular, or pellet-shaped carbon with a porous structure. Its main component is carbon, with trace amounts of oxygen, hydrogen, sulfur, nitrogen, and chlorine. It also possesses a fine structure like graphite, but with smaller crystal grains and irregularly stacked layers. It has a large surface area (500-1000 m²/g). It has adsorption capabilities, with substances that are more easily adsorbed on its surface. The greater the pressure, the lower the temperature, and the higher the concentration, the more the adsorption. Conversely, reducing pressure and increasing temperature is favorable for desorption of gases.

Activated carbon is commonly used for gas adsorption, separation and purification, solvent recovery, decolorization of syrups, oils, glycerin, as deodorizers for drinking water or refrigerators, filter agents for gas masks, and can also be used as a catalyst or as a trap for metal salt catalysts. Exhaust gases are powered by a fan and enter the activated carbon吸附 chamber under positive or negative pressure. Due to the presence of unbalanced and unsaturated molecular attractions or chemical bonds on the solid surface of activated carbon, when this solid surface comes into contact with the gas, it can attract gas molecules, causing them to concentrate and remain on the solid surface. Pollutants are thus adsorbed. After passing through a filter, the exhaust gas enters the activated carbon吸附 tower for purification, achieving high-altitude emissions that meet standards.
