<p>PURPOSE:To carry out the recovery of a solvent in good efficiency by stable operation, by memorizing the control of starting and stopping times of a compressor, protection of the compressor when operation thereof is started, drive and monitor of the compressor and the efficiency operating method of an evaporator. CONSTITUTION:When a definite time is elapsed from the initiation of desorption, amount of heat flowed into an evaporator comes to a steady state and, therefore, the operation of a compressor 5 is initiated by a timer 11. In this time, a bypass valve 12 is opened in order to avoid abrupt pressure variation of a steam recovery line to start the operation of said compressor and gradually closed after constant speed rotation is attained to change over the operation thereof to load operation. Until desorption is completed from this time, the compressor 5 is operated automatically and continuously but desorbed steam can be almost self-supplied in an apparatus.</p> |
