Activated carbon adsorption equipment can be applied to petrochemical, pharmaceutical and chemical, pesticide and chemical, coating industry, coating industry, packaging and printing industry, leather industry, microfiber (artificial leather), ultra high molecular weight polyethylene fiber (PE fiber) and other industries. Purification of exhaust gas, adsorption and reuse of organic substances in the exhaust gas, reuse, reduce consumption, reduce pollution.
The activated carbon adsorption equipment can adsorb and reuse solvent with relatively low boiling point, including: benzene, toluene, xylene, chlorobenzene, solvent oil No. 150; methanol, ethanol; acetone, methyl ethyl ketone; formic acid, acetic acid, methyl acetate, gasoline Wait for the solvent. The type of activated carbon is determined by the solvent, such as toluene activated carbon when reusing toluene, and gasoline activated carbon when using gasoline.
The VOC organic waste gas adopts a pretreatment process before entering the adsorber, including filter bag filtration, washing, humidity control and the like, removing dust, high boiling point or easily polymerized harmful substances, prolonging the service life of the activated carbon, and the treated VOC enters the activated carbon layer. The solvent is adsorbed, and the air in the VOC organic waste gas is discharged through the adsorber exhaust pipe.
The vapor is desorbed as a heat source, and a mixed vapor of steam and solvent is formed to leave the activated carbon adsorption-desorber, and a mixture of a solvent and water is obtained by condensation cooling. If the solvent is insoluble in water, the solvent is used to separate the solvent, such as benzene, toluene, etc.; if the solvent is soluble in water, the solvent, such as methanol or acetone, is extracted by distillation, extraction or rectification.

The activated carbon adsorption equipment is designed for fully automatic process control and can be left unattended during operation. Manual process can also be used according to user requirements. The VOC organic exhaust line and the valve actuators in the adsorber are pneumatically designed to meet the explosion protection requirements of the solvent reuse process.
The adsorption efficiency is up to 90%, the adsorption capacity is large, and the application is wide, activated carbon has a wide range of sources and low price;
Simple operation, safe and reliable, easy to maintain, no need for too much manpower input requirements;
Large specific surface area, good selective adsorption, can simultaneously process a variety of mixed exhaust gases;
