一.模拟移动床仪器介绍

模拟移动床一种利用吸附原理进行液体分离操作的传质设备。它是以逆流连续操作方式，通过变换固定床吸咐设备的物料进出口位置，产生相当于吸附剂连续向下移动，而物料连续向上移动的效果。这种设备的生产能力和分离效率比固定吸附床高，又可避免移动床吸附剂磨损、碎片或粉尘堵塞设备或管道以及固体颗粒缝间的沟流。

模拟移动床把固定吸附床分为许多段(常为24段)，段内装有吸附剂，段间液体不能直接流通。每段均装有进出口管道(进出两用)，由中央控制装置控制其进出。24个进出口中的20个只起段间联系的作用，另四个供四股物料的进入或离出，某一瞬间的物料进出口位置(图1[ 模拟移动床工作原理])把整个吸附床层分成了四个区，各区距离不等长，每段相际传质也不同。如A脱附区液体中含有A与D，此区是用D使A脱附。B脱附区是用 A及D使B脱附。由上述两区之间的出料口所引出的吸附液只含 A与D，而且A的浓度也较大。A吸附区是使原料中A与B分离，因此在A吸附区上部取出的吸余液中不含A而只含B与D。若吸附剂固定不动,则随着时间的推移，固相中被分离组分的浓度将自下而上逐渐变大。模拟移动床则是利用一定的机构，使四个物料的进出口以与固相浓度的变化同步的速度上移。这样，构成一闭合回路，其总的结果与保持进出口位置不动，而固体吸附剂在吸附器中自上而下移动的效果基本相同。

A simulated moving bed equipment is introduced

Using a simulated moving bed adsorption principle for liquid separation operation of mass transfer equipment. It was based on the current way of continuous operation, through the transformation of fixed bed adsorption equipment import and export of materials, produce continuous moves down, the equivalent of adsorbent materials and the effect of continuous moving up. This kind of equipment of production capacity and separation efficiency is higher than fixed bed adsorption, and can avoid moving bed adsorbent wear dust, debris or blockage equipment or pipeline ditch flow between the seam and solid particles.

Fixed simulated moving bed adsorption bed is pided into many segments (24), segment with adsorbent, liquid can not directly between the circulation. Each segment are equipped with the import and export pipeline (in and out of the dual), by the central control device to control the in and out. 24 import and export of 20 only has a function in period of contact between the other four for four strands of materials into or out, a moment of materials import and export position (figure 1 [principle] simulated moving bed) the whole adsorption bed is pided into four area, district distance before long, the event each phase mass transfer are also different. As A stripping zone in the liquid containing A and D, the area was use D to make A stripping. Stripping zone is to use A and B D B stripping. By the above are connected between the discharging mouth of absorption liquid contains only A and D, and the concentration of A bigger also. Adsorption zone is A separation of A and B in the raw material, so in A upper adsorption zone out in the residual liquid does not contain A and B and D only. If adsorbent stationary, as time goes on, the concentration of the solid phase is separated components will increases gradually from bottom to top. Simulated moving bed is to use a certain organization, make four materials import and export with the change of the concentration of solid phase synchronous speed up. So, constitute a closed loop, the import and export position still, the overall result and keep the solid adsorbent in the adsorber top-down mobile effect is basically the same.
