Patent ID: 7964094

Claim:
A solvent filtration and recovery system for filtration and recovery of a solvent-based liquid used in dry cleaning, said system comprising: a filtration tank, the filtration tank defining a filter chamber, the filter chamber being in fluid flow communication with at least one first opening of the filter chamber for ingress of a solvent-based liquid and egress of a by-product, at least one second opening of the filter chamber for initial draining of the solvent-based liquid, and at least one third opening of the filter chamber for egress of the solvent-based liquid, the filtration tank having a plurality of filters for filtering the solvent-based liquid in a filtration procedure, the plurality of filters being adapted to accumulate the by-product during the filtration procedure, and a recovery tank in fluid flow communication with the filtration tank through a main drain in communication with the first opening and an auxiliary drain in communication with the second opening, the recovery tank including a front portion and a back portion defining a slanted surface, the slanted surface in communication with a filter portion having a secondary filter for filtering the by-product, a reservoir for storing the solvent-based liquid and for receiving said liquid from both the recovery tank and from the filtration tank, wherein the filtration tank and the recovery tank establish a non-pressurized system for the movement of the by-product and filtration of the solvent-based liquid.
