A dry cleaning solvent recovery and filtering system includes a dry cleaning solvent tank containing solvent for use in a dry cleaning machine. A filtration path from the tank includes a centrifugal separator for removing coarse debris and a filter element for removing fine debris from the solvent fluid. The filter element includes a perforated metal cylinder, having an open mouth, with a Teflon.RTM. coated screen forming the interior debris collection surface. A rinsing spray nozzle situated at the mouth of the filter element directs a fluid spray under pressure against the collection surface in the same direction that debris contaminated solvent fluid flows therethrough. The pressure of the fluid spray is sufficient to dislodge fine debris adhered to the collection surface without forcing the debris into the perforations of the filter element.

A separation apparatus for separating immiscible liquids is disclosed which includes an apparatus of four tanks including outlets of differing heights to provide for separation of the immiscible liquids according to their specific gravities. The apparatus is complete in itself and is operable to separate the heavier than water solvents and the lighter than water solvents from water without need for alterations of the design or other special provisions.

A method is disclosed herein for recovering a vaporous material from a continuous gas stream. Two charcoal filter assemblies are mounted for raising into a passageway defined by a chamber. The charcoal filters may alternately be lowered from the passageway and into a container for regeneration. The container is filled with water which is then heated to vaporize an azeotrope of the water and the material adsorbed by the charcoal. The water is then drained from the container, and the filter is returned to its position within the passageway.
