Embodiment Construction

[0012] Such as figure 1 , to simulate the resin filling system in moving bed separation technology, including backwash tank 2, ion exchange column 11 and centrifugal pump 7 and other parts.

[0013] The resin tank 3 is injected with deionized water through the water inlet 1, and under the action of the first diaphragm pump 4, the resin is transported into the backwash tank 2, and the outlet 5 of the backwash tank is directly connected to the ion exchange column 11 through the pipeline 6 On the resin filling port 12. That is to say, when the separation medium of the simulated moving bed system migrates between devices, the diaphragm pump is no longer used as the power, but the existing centrifugal pump 7 in the system is used as the power, which reduces the blockage of the diaphragm pump and the frequent use of the diaphragm pump. question.

[0014] The specific process is: the outlet 5 of the backwash tank is no longer installed with a diaphragm pump, and is directly connec...

Abstract

The present invention discloses a resin filling system in a simulated moving bed separation technology, and belongs to a simulated moving bed separation technology. The resin filling system comprises a back washing tank, an ion exchange column and a centrifugation pump, and is characterized in that an outlet of the back washing tank is directly connected with a resin filling port of the column through a soft pipe, an outlet pipe is arranged in front of an outlet valve of the centrifugation pump, and the outlet pipe is connected with a middle flange of the back washing tank through a soft pipe to form a deionized water closed cycle. With the system, a use amount of deionized water can be effectively reduced, and problems caused by diaphragm pump blockage and multiple uses of the diaphragm pump are reduced.

Description

technical field [0001] The invention relates to a simulated moving bed separation technology, in particular to a resin filling system in the simulated moving bed separation technology. Background technique [0002] In the simulated moving bed chromatographic separation system, the filling of the separation medium (resin) is a process that the chromatographic system must go through, such as figure 2 , the resin tank 3 is injected with deionized water through the water inlet 1, and under the action of the first diaphragm pump 4, the resin is transported to the backwash tank 2, and the second diaphragm pump 41 is installed at the outlet 5 of the backwash tank, and then through the pipeline 6 Connected to the resin filling port 12 of the ion exchange column 11, under the action of the second diaphragm pump 41, the migration of the separation medium (resin) into the ion exchange column is realized. The main purpose of using the second diaphragm pump as the output power to input ...
