ABSTRACT:
A device and a related method are provided for reclaiming or recovering dry cleaning solvent from otherwise disposable fluid contained within a separator or other suitable receptacle of a dry cleaning machine. The device includes an evaporator and a fluid transfer mechanism for transporting fluid evaporated by the evaporator through a filter that removes substantially all of the solvent present within the evaporated fluid. Alternatively, a filter can be interposed between the separator or other suitable receptacle and the evaporator so that solvent is filtered before reaching the evaporator. Consequently, the device substantially reclaims or recovers dry cleaning solvent that may still be present within the fluid that is to be otherwise disposed of from the separator or other suitable receptacle.
