ABSTRACT:
A spent solvent purification apparatus for treating spent acetone includes an evaporation unit, a condensing unit, and a housing for the units which has upper and lower sections and a panel section that divides the housing interior into separate compartments for the respective units. The evaporating unit is housed by the upper section and it includes a container with an interior wall that divides the interior into upper and lower chambers. The lower chamber has a heater for heating a heat exchange fluid that is contained therein and the upper chamber is for containing the spent solvent during the batch distillation procedure to which it is subjected. Both chambers have temperature sensors which are designed to break the control circuit when the temperature in either chamber exceeds a temperature that is predetermined and set for each sensor. The condensing unit is in the lower compartment of the housing and it is suspended from a preformed portion of the panel section which is designed to support the heat exchanger in a manner such that the condensate formed therein flows to the condensate discharge outlet of the heat exchanger by gravity. The bottom section of the housing provides a reservoir for cooling water which, by means of a pump, is circulated between the reservoir and heat exchanger located in the lower compartment.
