This device is developed as solvent recovery device for metal cleaning.
The system is following.

• Vapor is sucked from the cleaning tank with suction blower, and then it is sent into the adsorber packed with activated carbon. (Adsorption process) (chart 1)
• In the adsober, vapor is adsorbed by the activated carbon and only clean air is discharged to the outdoors air. (Desorption process) (chart 2)
• The activated carbon in the adsorber is heated by steam, so that adsorbed solvent is desorbed. (chart 3)
• Solvent and steam are sent into the condenser and condensed and liquefied. (chart 4)
• Liquefied solvent and steam are separated into solvent and water by the water separator. (chart 5)
• Recovered solvent is discharged from the recovery solvent outlet and can be reused. (chart 6)
• Separated water may be mixed with solvent( subject to the kinds of solvent), so it is aerated in the aeration tank and vapor is sent into the adsorber with the suction blower. (chart 7)
• Aerated water can be used makeup water in the cooling tower. (chart 8)
  

These series of flow enables closed system.

The key to the antipollution measure is to prevent diffusion at emission source.
This closed system promotes the effect of the antipollution measure by device suited for each company.
We believe that the buildup of its effect will lead to zero emissions in washing process.
