<p>Provided are an expanded bed chromatographic separation column for a biochemical separation process and a technical process thereof. By providing a pressure equalization liquid distributor having a self-cleaning function below a porous blocking sieve plate (301) at the bottom of the expanded bed, and providing an upper part nozzle assembly having a backflush cleaning function at the top of the expanded bed, the expanded bed chromatographic separation column is suitable for treating a feedstock liquor (307) having solid particulate impurities, and at the same time a better distribution of the feedstock liquor (307) added into the expanded bed can be achieved, ensuring that the fluid passed through the expanded bed layer displays a state of piston flow. The expanded bed chromatographic separation column and the technical process thereof have the following advantages: they greatly increase the separation theoretical value and the chromatographic separation efficiency of the expanded bed; improve the utilization result effect and efficiency of the expanded bed; and increase the adsorption load and the desorption resolution of the expanded bed.</p> |
