Abstract

PURPOSE:To make a device compact and to extremely reduce a cost by executing the condensation and cooling of a solvent in a drying process and a distilling process with the two steps of a primary capacitor, which causes the gaseous solvent to be liquid, and a secondary condenser which decreases the temperature of the liquid solvent to a prescribed temperature. CONSTITUTION:The condenser to be used for the drying process is divided into the two steps of a primary condenser 10a and a secondary condenser 10b. As the cooling source of the primary condenser 10a, a cooling tower is used, for example, when the solvent to be needed to cause the gas solvent to be the liquid is perchloroethylen and a chiller is used when the solvent is CFC-113. As the cooling source of the secondary condenser 10b, the chiller is used, for example, when the liquid solvent to be needed to cool the solvent to the desired temperature is perchloroethylen, and a refrigerating machine is used when the solvent is CFC-113. The condenser to be used for the distilling process is also divided into the two steps of a primary condenser 12a and a secondary condenser 12b. As the cooling source of the primary condenser 12a, the cooling tower is used whenever the solvent is perchloroethylene or CFC-113. As the cooling source of the secondary condenser 12b, the chiller is used whenever the solvent is perchloroethylene or CFC-113.

Unlike dry cleaning machines that use water for cleaning, it is necessary to ensure that the used solvent does not leak out of the machine and that it is not discharged as much as possible. The higher the amount of leakage or emissions, the higher the cost, and
In particular, there is the important issue of pollution.

The temperature of the condenser used in the drying process needs to be as low as possible in order to condense and recover the solvent vaporized in the air and reduce the amount of solvent remaining in the air. A refrigerator 14 was used, and a large-capacity refrigerator had to be installed as described later.

Further, the temperature of the solvent recovered in the distillation step is preferably 25° C. or lower. The reason for this is that when the temperature of the solvent becomes high, dyes on clothing tend to bleach, and cavitation occurs in the pump, making it impossible to pump liquid. For this reason, conventionally, a chiller had to be used to cool the condenser 12, and a chiller with a large capacity had to be used.
