Abstract
A distillation solvent recycling system is provided which is characterized by improved safety features, modular construction, a double insulated solvent reservoir, electronic control and display of system parameters, and self diagnosis of system malfunctions. The components of the system are assembled into a compact unitized structure so as to maximize safety, efficiency, portability, convenience and ease of operation and maintenance. An outer insulative and protective safety casing shields the operator from process hazards while the system is in operation. An inner lid is provided with improved sealing mechanisms for preventing the escape of toxic solvent vapors. An outer safety lid shields the operator from heat and trace vapors in the vicinity of the solvent reservoir.
Claims32
A solvent recycling system comprising in integral unitized combination:
- evaporator means having contaminated liquid solvent inlet means and solvent vapor outlet means;
- means for heating contaminated liquid solvent in said evaporator means;
- means for controlling said means for heating solvent;
- inner closure means for said evaporator means located at said liquid solvent inlet means, said inner closure means including means for automatically relieving pressure which is higher than a predetermined pressure build up within said evaporator means;
- outer insulative and protective safety casing for said solvent recycling system comprising an outer closure means for said evaporator means positioned for access to said inner closure means and said evaporator means, said outer closure means shielding a system operator from solvent discharged when said inner closure means relieves pressure build up within said evaporator means;
- means for receiving and condensing solvent vapor from said evaporator means, and
- means for collecting purified solvent condensate, said means for controlling said means for heating including means for sensing the temperature of solvent in said evaporator means and means for electronically monitoring temperature change and discontinuing the heating when the temperature change meets or exceeds a predetermined value.
