International voices for global environmental protection are increasing, and even in Japan,
Since July 1, 1989, the regulation law for CFCs has been adopted to regulate the production and consumption of five types of CFCs. It is expected that this regulation will become stricter, and measures are being taken from various perspectives such as conversion to alternative products in various fields.

Is unable to sufficiently liquefy and condense the thick solvent gas generated from the cleaning tank, and during cleaning and drying where a large amount of solvent gas is generated, the solvent gas is cooled and condensed, and then adsorbed on activated carbon. However, the burden on activated carbon is large and it is necessary to install a large capacity activated carbon tank. Further, the emission of solvent gas into the atmosphere is unavoidable, which causes a problem of ozone layer depletion, the solvent gas cannot be completely recovered, and a countermeasure against solvent loss is required.

A separator is used to separate oil and water, and the solvent gas generated from the cleaning tank during cleaning and drying is configured to be adsorbed on the activated carbon through the third condenser. In particular, a part of the solvent gas generated from the cleaning tank is absorbed. The third condenser condenses and collects, and at the same time, a part of the dilute solvent gas that could not be completely condensed by the third condenser is adsorbed on the activated carbon. The concentrated solvent gas is frozen and condensed to the activated carbon. This is to reduce the load and improve the recovery rate of the solvent gas.

CClF 2 CF 2 CHClF or CF 3 CF 2 CHCl
A mixture of 2 and CClF 2 CF 2 CHClF is used as a solvent for dry cleaning to wash clothes and other textile products and leather products, the solvent after the washing is distilled, and the evaporated solvent gas is condensed in the second condenser. After the liquefaction, oil and water were separated by a separator, which enabled 99% of the recycled amount. A large amount of non-condensable gas is generated in low boiling point solvents,
Solvent gas cannot be adsorbed on activated carbon 100%.
Therefore, after the solvent gas from the cleaning tank is first condensed by the third condenser, the dilute solvent gas is adsorbed on the activated carbon to reduce the load on the activated carbon, and the conventional CFC-1 is used.
It was designed so that the alternative CFCs could be used with a little cost by slightly modifying the dry cleaning device for 13 and adding a cooling chiller and a third condenser.

な回収液は再利用に供することが出来る。As described above, the present invention provides the third condenser for liquefying and condensing the concentrated solvent gas generated from the cleaning tank during the use of the alternative CFC, so that the amount of solvent gas generated during cleaning can be increased. During drying, the solvent gas is cooled and condensed by the circulation system between the condenser and the cleaning tank.
After that, the load on the activated carbon can be reduced by adsorbing it on the activated carbon. Therefore, it is not necessary to install a large capacity activated carbon tank. Further, by closing the entire system, it is possible to prevent the solvent gas from being diffused into the atmosphere, solve the problem of ozone layer depletion, and reuse the expensive recovery liquid.
