1results about How to "Raise the suction temperature" patented technology

The application relates to a liquid return prevention distillation system, belonging to the technical field of waste liquid treatment, which is characterized in that a phase change energy storage tank is arranged between an evaporation kettle and a condenser, the first electromagnetic valve and the third electromagnetic valve are opened, and the second electromagnetic valve is closed before the compressor is started, the phase change energy storage tank is in an evaporation section, the suction temperature is improved, and the liquid return phenomenon is avoided, the second electromagnetic valve is opened, the first electromagnetic valve and the third electromagnetic valve are closed after the evaporation kettle boils, the phase change energy storage tank is in a condensation section, the phase change energy storage tank absorbs heat, energy storage for the next start after discharge is facilitated, and quick start is realized.
