The activated carbon solvent recovery device utilizes the advantages of high-efficiency adsorption material – activated carbon fiber (ACF) with strong adsorption capacity and fast adsorption speed to recover organic solvents.

A typical device consists of a blower, an air filter, three adsorption and desorption tanks, a switching valve, a condenser and a separator.

Desorption with water vapor. Through the switching of the valve, the adsorption and desorption of the solvent in the three adsorption and desorption tanks are realized.

The desorbed solvent and water vapor enter the condenser for condensation, and the pure solvent can be obtained after liquid separation.

The activated carbon fiber organic waste gas recovery device is composed of three adsorbers together to form a pipeline system, which can be switched during operation.

When adsorber A is adsorbed, adsorber B is desorbed, and adsorber C is cooled and regenerated.

When the organic waste gas enters the adsorber, the organic matter in it is adsorbed after passing through the activated carbon fiber felt, and the purified gas is discharged from the top of the adsorber.

The three adsorbers A, B and C are switched alternately.

The system uses steam as the desorbent. The desorption steam enters from the top of the adsorber, passes through the activated carbon fiber felt, and desorbs the adsorbed and concentrated organic matter and brings it into the condenser.

After condensation, the mixture of organic matter and water vapor is condensed and flows into the stratification tank.

Sedimentation separation to achieve the purpose of recovering organic matter.

The separated water is discharged to the factory chemical sewage system for centralized treatment and then discharged.

All the action switching during the system operation is completed by the automatic control system.
