摘要:
A system and method are provided for dry cleaning articles utilizing a siloxane solvent. The system (5) includes a cleaning basket (10) for receiving articles therein and one or more tanks (14, 16) for containing a siloxane solvent. Coupled between the tank and the cleaning basket is a pump (12) for immersing the articles in the cleaning basket with the siloxane solvent. Also included is a still (24) for distilling the dirty siloxane solvent to recover the pure siloxane solvent. A condenser (26) is coupled to the cleaning basket and/or the still for recovering condensed vapors. For decanting any water in the siloxane solvent received from the condenser, a separator (28) is coupled to the condenser. A fan (32) is coupled to the cleaning basket for circulating air past the condenser, then the heater coils (34) and into the cleaning basket for drying and cooling the articles.

A system and method are provided for separating water from solvent during dry cleaning. Included is an inlet (52) capable of receiving a mixture of dry cleaning fluid and water from a basket of a dry cleaning apparatus. The dry cleaning fluid includes a siloxane composition. Also provided is a flow controller (60) for urging flow of the mixture received from the outlet. Coupled to the flow controller (60) is a coalescent media (64) that receives the mixture urged by the flow controller (60). A chamber (68) is coupled to the coalescent media (64) for receiving the mixture from the coalescent media (64) to separate the water and the dry cleaning fluid. Also coupled to the chamber (68) is an outlet (69) to remove the dry cleaning fluid from the chamber (68) in the absence of water.
摘要:
A dry cleaning system and method comprises dry cleaning machinery used in conjunction with a cyclic siloxane solvent. In order to enhance the cleaning capabilities of the cyclic-siloxane-based solvent, such solvent is modified with a chemical that is selected from the group of chemicals including 2-ethylhexyl acetate, esters, alchohols, and ethers.
摘要:
A dry cleaning system and method comprises specially designed or modified machinery used in conjunction with a cyclic siloxane solvent. In a preferred embodiment, the method comprises the steps of loading articles into a cleaning basket; agitating the articles and the siloxane composition in which they are immersed; removing most of the siloxane composition; centrifuging the articles; subjecting the articles to a partial vacuum pressure and elevated temperature; and removing the articles from the basket after cooling the articles and returning the pressure to ambient.
