Application of activated carbon fiber
Solvent adsorption recovery system equipment

This device is an exhaust gas treatment equipment that exposes a large number of organic solvents and effectively adsorbed pores in the atmosphere and exhaust gas to the surface and deodorizes. Because the structure of high-performance activated carbon fiber (ACF) adsorbent is fibrous and its outer surface area is very large, it can recover odor harmful substances. Therefore, high-performance activated carbon fiber (ACF) has the characteristics of very fast speed and very high adsorption capacity.


  • Lightweight structure and high efficiency

Comparing ACF and granular activated carbon in the equipment, the adsorbent has the ability to handle 1/20 to 1/100 of the filling volume.

  • The recovered solvent is of high quality

Due to the short evaporation time of water vapor (5 to 6 minutes), high-quality solvents with less thermal influence can be recovered.

  • Economical and energy-saving

The adsorption chamber can be switched completely automatically and continuously. Because desorption consumes a certain amount of steam and cooling water, it is equipped with a small steam boiler and cooling tower.

  • High security

The thickness of the adsorption layer is about 1/5 to 1/10 of that of granular activated carbon, so there is no adsorption heat and it is safe.

  • easy to use

The adsorption and desorption functions can be switched automatically in a short period of time, and the solvent recovery device can be stopped at any time according to the production site conditions.
