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).
