Embodiment
The preferred embodiment of the utility model is illustrated below in conjunction with attached drawing, it will be appreciated that described herein excellent
Select embodiment to be only used for describing and explaining the present invention, be not used to limit the utility model.
A kind of toluene condensate recycling device of the utility model, including piping filter 1, ice chest 3, water cooling heat exchanger 2, first
Knockout drum 4, compression refrigerating machine 5, the second knockout drum 6, accumulator tank 9, the piping filter 1 and the one of ice chest 3
End connection, the other end of the ice chest 3 are connected with one end of the first knockout drum 4, and water cooling heat exchanger is equipped with the ice chest 3
2；The other end of first knockout drum 4 is connected by compression refrigerating machine 5 with the second knockout drum 6；Described first
The afterbody of 4 and second knockout drum 6 of knockout drum is connected with accumulator tank 9, and the compression refrigerating machine 5 includes T ends and C
End, the compression refrigerating machine T ends 51 are connected with the other end of the first liquid knockout drum 4, the compression refrigerating machine C-terminal 52 and water
Cold heat exchanger 2 connects, and the piping filter 1 is OCr18Ni9 stainless steel pipes filters, the ice chest 3 and water cooling heat exchanger
2 be aluminum plate-fin heat exchanger, and repid cut-off valve 8, the compression system are equipped with 51 air inlet of compression refrigerating machine T ends
