ABSTRACT:
A modular solvent recovery device (30) includes an enclosure (34) mounted to a frame (32) to enclose a tank (70) having a solvent section (72) and a waste fluid section (73), a still (40) in which waste photopolymer fluid is distilled by application of heat and vacuum pressure to the waste photopolymer fluid to distill a solvent from the waste photopolymer fluid and reduce the waste photopolymer fluid to a coalescing concentrated residue, and a flash-point-increasing agent delivery system (95) to supply a flash-point-increasing agent to the concentrated residue in an amount sufficient to raise the flash point temperature of the coalescing concentrated residue to a predetermined temperature. The still has a manhole device (46) comprising a pivotally and telescopically mounted closure (47) having wheels (51) rotatably mounted thereto and tracks (52) mounted to the still to engage the wheels and raise the closure vertically above a manhole (42) of the still upon pivotal movement of the closure. A housing (112) is provided to enclose ultrasonic fluid level sensors (111).
