Liquid-liquid-liquid triphase horizontal continuous lifting stirring extraction device

Abstract

The liquid-liquid-liquid three-phase continuous lifting and stirring extractor includes one horizontal reactor with two stuffing-holding isolating board cases in its two ends; one upper shaft and onelower shaft penetrating the reactor side walls and installed parallelly to the isolating board cases; upper baffle and lower baffle with horizontal arc lift tank in between; light phase outlet, middle phase inlet and heavy phase outlet successively arranged on one side wall of the reactor; light phase inlet, middle phase outlet and heavy phase inlet successively arranged on the opposite side wallof the reactor; and motor driven wheels installed in the ends of the two shafts. With simple structure, low power consumption, flexible operation, no emulsification and less back mixing, the presentinvention is suitable for separating and purifying high-value biochemical product from relevant fermented liquid.

Description

field of invention [0001] The invention belongs to a liquid-liquid-liquid three-phase continuous extraction device, in particular to a liquid-liquid-liquid three-phase (heavy phase, intermediate phase, light phase) horizontal continuous lifting device for separating target products from complex mixed systems The stirring extraction device is especially suitable for the separation and purification of high value-added biochemical products from the fermentation liquid of biological products using a three-phase one-step method. Background technique [0002] As a traditional means of separation and purification, solvent extraction has a history of hundreds of years, and it is widely used in the fields of petroleum, chemical industry, pharmaceutical, metallurgy, environmental protection and bioengineering. However, with the continuous development of the process industry, especially the rapid development of the bioengineering and biochemical pharmaceutica...

Problems solved by technology

Although the invention of the device provides a feasible solution for large-scale liquid-liquid-liquid three-phase continuous extraction in industry, the device still has some shortcomings, such as low mass transfer efficiency and extraction efficiency, because the The equipment actually connects the two-stage liquid-liquid extraction process in series, and does not really realize the liquid-liquid-liquid three-phase in-situ continuous extraction

The existing experimental results show that the efficiency of liquid-liquid-liquid three-phase in-situ extraction can reach more than 80%, which is much higher than the efficiency of the two-stage liquid-liquid extraction series process (extraction efficiency is only 62%)
