ABSTRACT:
An apparatus for recycling the stripper solutions with higher recycling rate is disclosed. The apparatus includes a stripper condenser; a first buffer tank; a second buffer tank connecting to said stripper condenser by a first pipe and connecting to said first buffer tank by a second pipe; a recycling device connecting to said first buffer tank by a fourth pipe; a first pump mounted on said first pipe; a second pump mounted on said second pipe; a concentration detector mounted in said stripper condenser; and a controller electrically connected to said concentration detector, said flow meter, and said liquid level sensor for receiving the signals therefrom, and electrically connected to said first pump and said second pump for sending on-off messages to said second pump.
