Embodiment Construction
[0013] like figure 1 , 2 As shown, the simulated moving bed chromatography device is mainly composed of a dynamic axial compression column 1, a computer 6, and a signal collector 7. Multiple dynamic axial compression columns 1 are connected in series or in parallel through the feed pipe 2 and the discharge pipe 4. , the feed pipe 2 of each dynamic axial compression column 1 is connected with other dynamic axial compression columns through the feed valve 3, and the discharge pipe 4 of each dynamic axial compression column is connected with other dynamic axial compression columns through the discharge valve 5 It is connected to the compression column, and a signal collector 7 is built in the outlet of each dynamic axial compression column. Each signal collector 7 is connected to the computer 6 through a signal line 8, and each feed valve 3 and discharge valve 5 are connected through a signal line. 8 is connected to computer 6 and constitutes a control device as a whole.

The invention relates to an analogue movable based spectrum device based on dynamic axial compression post technique, wherein all dynamic post 91) via the feeding tube (2) and the outlet tube (4) are serially or parallel connected; the inlet tube (2) of each dynamic post (1) via the inlet valve (3) is connected to other dynamic post; the outlet tube (4) of each dynamic tube via the outlet valve (5) is connected to other dynamic post; the signal collector is arranged at the outlet position inside the dynamic post; all signal collectors (7) via the signal line (8) are connected to the computer (6); the outlet and inlet valves (3, 5) are connected to the computer (6) via signal line (8) to form the manage system. The invention uses signal collector to collect the sample density signal to be compared with the storage information to switch the valve, to complete feeding and collecting product, and realize the analogue motion of dynamic posts, to realize batch production.
Description
Technical field [0001] The invention relates to a chromatographic separation device, in particular to a simulated moving bed chromatographic device based on dynamic axial compression column technology. Background technique [0002] In 1946, U.S. General Petroleum Corporation (UOP) developed a countercurrent continuous circulation moving bed device (TMB) for the separation of small molecular weight hydrocarbons. During the separation process, the stationary phase moves from top to bottom due to the action of gravity, and passes through the cooling zone, adsorption zone, rectification zone and desorption zone in turn, and after reaching the bottom, the desorption is complete. The activated carbon is lifted from the gas to the top for reuse, and the mobile phase water vapor moves from the bottom up. This method was commercially applied in the 1960s. Because the flow rate of the stationary phase of this system is difficult to control and easy to wear, it is extremely difficult t...
