High pressure liquid/gas storage frame for a pressurized liquid cleaning apparatus
First Claim
1. An apparatus for removing a contaminant from a substrate using a pressurized cleaning fluid comprising, in combination:
- a substrate cleaning vessel having an inlet for introducing substantially uncontaminated pressurized cleaning fluid and an outlet for removing a solution of the contaminant in the pressurized cleaning fluid;
a cleaning fluid recovery device for separating the contaminant from the cleaning fluid to provide substantially uncontaminated cleaning fluid at a recovery device outlet, the cleaning fluid recovery device being in fluid communication with the substrate cleaning vessel through the cleaning vessel outlet; and
a structural framework supporting the substrate cleaning vessel and the solvent recovery device comprising a plurality of interconnected hollow structures in fluid communication with the substrate cleaning vessel for receiving and storing the pressurized cleaning fluid.

Abstract
A pressure vessel for receiving and storing pressurized fluid in a pressurized dense phase liquid dry cleaning apparatus is provided. The dry cleaning apparatus generally includes a cleaning vessel within which garments or the like are cleaned and a solvent recovery device which takes the contaminated cleaning fluid from the cleaning vessel and separates out the contaminants. The pressure vessel comprises a plurality of interconnected hollow structures and as such is substantially self-supporting and occupies less space within dry cleaning apparatus. The pressure vessel can also serve as the support structure for the other components of the dry cleaning system to provide a further cost and space savings.
