Abstract

The invention discloses a macroporous resin adsorption plant of a liquid-solid circulating fluidized bed, including: an upstream bed; a downstream bed arranged parallel to the upstream bed connecting to a lower portion of the downstream bed via a lower circulator, and the downstream bed is provided with a butterfly valve and a liquid distributor arranged in correct order from up to down; a liquid-solid separator, which top connects with a top of the upstream bed, and which bottom connects with an upper section of the downstream bed; a feed liquid reservoir; a waste fluid storage tank; a wash trough; an eluent storage tank; a product storage tank; two pressure sensor; a conductivity meter and a computer. Compared with a fixed bed and a conventional fluidized bed, the plant of the invention has well cycling and adsorption separating condition in a practical operation process, thus is capable of achieving a continuous process of ginkgo flavone adsorption and desorption operation, as well as realizing industrialized popularization.

Description

technical field [0001] The invention relates to an adsorption device, in particular to a liquid-solid circulating fluidized bed macroporous resin adsorption device. Background technique [0002] Due to the uneven dispersion of liquid and solid in static adsorption, low mass transfer rate, and long adsorption and elution time, the adsorption separation of ginkgo flavonoids is mainly operated in fixed bed and expanded bed at present. Although the fixed bed operation has high stability, it is easy to block the flow channel when solid impurities exist. The disadvantage of the expanded bed is that the adsorption, cleaning, elution, and regeneration all need to be switched, and the operation of the fixed bed is also performed intermittently. Since the four different operation modes of adsorption, cleaning, elution and regeneration need to be switched continuously, the operation is cumbersome and time-consuming. The circulating fluidized bed is now mainly used for the separation ...
