摘要:
The present invention provides a dry cleaning system arranged for washing articles employing a cleaning solution. The dry cleaning system includes a wash tank (2) for washing an article to be washed with a cleaning solution. The wash tank (2) is arranged for washing the article at an increased pressure compared to atmospheric pressure. The dry cleaning system includes a fluid displacement device (1), such as a pump, connected to the wash tank (2) and is arranged for transferring the cleaning solution through the dry cleaning system in a first operational mode. The fluid displacement device is arranged to reduce the pressure in the wash tank towards atmospheric pressure in a second operational mode.
摘要:
The present invention refers to the use of an adsorbent comprising particles comprising an amorphous phase and a crystalline phase for the purification of dry cleaning solvents. The present invention furthermore relates to a filter unit containing such an adsorbent. It also refers to a dry cleaner containing a filter according to the invention. Additionally, the present invention refers to a process for dry cleaning textiles, wherein an adsorbent according to the invention is used.
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.

The invention relates to a non-aqueous washing machine, methods of using the machine, methods of washing, and recycling and modular components and subsystems thereof.
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.
