Resin column purification system for backwashing

Abstract

The invention relates to a resin column purification system convenient for backwashing, belonging to the technical field of plant extract purification equipment. The resin column purification system comprises a plurality of resin columns which are arrayed in parallel, a plurality of pipelines for connecting the resin columns, and a plurality of valves arranged on the plurality of pipelines; the pipelines comprise an upper column general pipe, a plurality of upper column branch pipes, a plurality of lower injection branch pipes, a lower injection general pipe and a plurality of reinjection pipes; each pipe is provided with one valve at least; the two adjacent resin columns are connected end to end by the reinjection pipes; the upper column general pipe, the upper column branch pipes, the lower injection branch pipes, the lower injection general pipe and the reinjection pipes are connected sequentially in series; and the plurality of resin columns are arranged in parallel. According to the resin column purification system, the serial connection and the parallel connection of the resin columns are converted according to actual requirements, so that a lot of primary purification can be realized and fine purification also can be realized; and the resin column purification system also can achieve the effects of partial serial connection and partial parallel connection.

Description

technical field [0001] The invention relates to a system composed of multiple resin columns, in particular to a resin column purification system which is convenient for backwashing. It belongs to the technical field of plant extract purification equipment. Background technique [0002] Resin column purification of plant extracts is a conventional technique in the art. After the resin column is used for a long time, the purification effect will become worse, so it is often necessary to wash with various chemical solutions to activate the resin, and the commonly used methods are acid washing, alkali washing and water washing. And backwashing is required to loosen the resin bed, thereby increasing flow. If the existing resin column needs to be flushed and backwashed, it often needs to be disassembled and sent to a professional institution for treatment; the online treatment effect is very poor, because not only need to use different agents but also require pressure from flush...

and requires backwashing to loosen the resin bed, thereby increasing flow

If the existing resin column needs to be flushed and backwashed, it often needs to be disassembled and sent to a professional institution for treatment; the online treatment effect is very poor, because not only need to use different agents but also require pressure from flushing to backwashing, The online flushing of existing equipment cannot adjust the pressure, and the effect of only relying on the pressure pump is very limited
