Description
Technical Field
The invention relates to the technical field of ceramic membrane separation, in particular to a separation system for a ceramic membrane process.
Background
Glucosamine (2-amino-2-deoxy-D-glucose, GlcN) is an important hexosamine, formed by replacement of one hydroxyl group of glucose with an amino group, and is readily soluble in water and hydrophilic solvents.
Most of the existing glucosamine is separated by adopting a ceramic membrane (also called inorganic ceramic membrane), which is an asymmetric membrane formed by preparing an inorganic ceramic material through a special process. The ceramic membrane is classified into a tubular ceramic membrane and a flat ceramic membrane. Note that "CT membrane" is not a alias of ceramic membrane, and this reference is actually a misstatement by laymen for english abbreviation of ceramic membrane. The tube wall of the tubular ceramic membrane is densely distributed with micropores, under the action of pressure, the raw material liquid flows in the membrane tube or outside the membrane, small molecular substances (or liquid) permeate the membrane, and large molecular substances (or solid) are intercepted by the membrane, so that the purposes of separation, concentration, purification, environmental protection and the like are achieved.
However, after the ceramic film is separated, some impurities may be attached to the surface of the ceramic film, and if the ceramic film is not cleaned for a long time, the impurities may block the ceramic film, which may affect the use.
