[0026] On both sides of the top of the membrane feed tank 6, an input port 5 and a first output port 7 are respectively provided. A sixth output port 25 is provided at the bottom of the membrane feed tank 6. At both ends of the concentrated residue tank 9, a second output port 10 and a seventh output port 26 are respectively provided. The sixth output port 25, the seventh output port 26 and the fifth output port 16 are connected to the input end of the feed transfer pump 23 through a fourth pipeline 24, and the white liquor can enter the nanofiltration membrane system 15 under pressure through the feed transfer pump 23.

[0027] The output end of the feed transfer pump 23 is connected to the input end of the high-pressure pump 21. A one-way valve 22 is arranged between the feed transfer pump 23 and the high-pressure pump 21. The output end of the high-pressure pump 21, the first output port 7, the second output port 10 and the third output port 12 are all connected to the input end of the shell-and-tube heat exchanger 19 through a second pipeline 8. The high-pressure pump 21 continues to pressurize, and the one-way valve 22 plays a role in stopping the flow and preventing backflow.

[0028] The output end of the shell-and-tube heat exchanger 19 is connected to the input end of the circulation pump 17. The output end of the circulation pump 17 is connected to the input end of the nanofiltration membrane system 15. Valves are provided on the connecting pipe between the shell-and-tube heat exchanger 19 and the circulation pump 17 and the connecting pipe between the circulation pump 17 and the nanofiltration membrane system 15. Cooling water is added into the shell-and-tube heat exchanger 19, which can keep the equipment at a lower temperature and reduce the alcohol loss in the white liquor.

[0029] Valves are fixedly installed on the first output port 7, the second output port 10, the third output port 12, the fourth output port 13, the fifth output port 16, the sixth output port 25 and the seventh output port 26.

[0032] Working principle: When the utility model is in use, first open the valve on the feed pipe 1, and the white liquor enters the bag filter 2 through the feed pipe 1. The bag filter 2 can filter out the macromolecular impurities inside the white liquor, improve the quality of the white liquor, and make the white liquor more clear and transparent. Then the white liquor enters the membrane feed tank 6 through the first pipe 4. When the membrane feed tank 6 reaches the high liquid level, start the feed transfer pump 23. After the whole system is filled with the liquor, start the high-pressure pump 21 to continue pressurizing. Finally, under the action of the circulation pump 17, the white liquor is transported into the nanofiltration membrane system 15. Under the action of pressure, the clear liquid passes through the separation membrane 29 and enters the product liquor tank 28, and the concentrated liquid flows back to the membrane feed tank 6 for further concentration. The shell-and-tube heat exchanger 19 can be used for cooling to maintain the equipment at a lower temperature, avoiding the loss of alcohol due to the increase in temperature during the operation of the white liquor.
