Abstract
A charged particles separator with vertical electrophoresis is composed of chromatographic bearing material, electrophoresis electrodes, material feeder and collector, and features that the electrophoresis field is perpendicular to flowing direction of fluid to turn the direction of charged particles, which are finally separated out by sample collector. Said separator can be used for continuous separation of charged particles from fluid, analysis, preparing purpose and fluid electrolysis.
Description
The invention belongs to the industrial separation and analysis separation equipment of utilizing principle of electrophoresis, specially refer to the separation equipment of the vertical electrophoresis charged particle that can be used for preparation continuously and sewage disposal.
Migration behavior-the electrophoresis of charged particle (organic filler and inorganic ions) under electric field action, but by people be used for separating, the many charged species undergoes of Analysis and Identification.Common as paper electrophoresis, flaggy electrophoresis and gel electrophoresis are used for many years by people, but all are to be purpose with the compartment analysis, can not realize preparing continuously purpose.
The present invention combines sorbing material and electrophoresis electric field, use vertical electric field, be that direction of an electric field is vertical mutually with fluid flow direction, when the fluid streamwise moves, wherein contained charged particle is by the migration perpendicular to fluid flow direction, because the carrying capacity and the particle itself of various particles vary in size, migration speed is different and separate.Owing to the wash-out effect of fluid, particle also longshore current body flow direction moves, and moves along curve track at last simultaneously.Fluid is collected by special collection method, the material after the separation is discharged from different collection mouths, thereby realize separating continuously and preparation, and can be used for large-scale industrial production process and water treatment procedure (as desalination, desalinization etc.).
The objective of the invention is to propose to be used for various objectives, the continuous vertical electrophoresis separation equipment of different occasions.Its apparatus-form comprises and is used for trace protein, biology enzyme, the mini-plant that bioactivator is purified and separated, also comprise and be used for the main equipment that extensive inorganic salts separate, comprise by chromatograph paper being the plane vertical electrophoresis equipment of backing material, also comprise with silica gel etc. being the three-dimensional vertical electrophoresis equipment of backing material.
Technical conceive of the present invention is: a kind of separation equipment of vertical electrophoresis charged particle is by equipment box (4), and the chromatography backing material is a pair of or some to iontophoretic electrode (5), feeder (1), and sample divider (6) is formed.The chromatography backing material can be used chromatograph paper (2) or chromatograph silica gel (8).The distribution of iontophoretic electrode (5) can be the pair of planar electrode, a pair of stereo electrod or two pairs of stereo electrods, its main feature is that formed direction of an electric field of electrode and fluid flow direction are perpendicular, make charged particle when longshore current body flow direction moves, be subjected to the electric field force effect to take place to realize separating perpendicular to the skew of fluid flow direction.
When using chromatograph paper (2) is backing material, when iontophoretic electrode (5) is taked the plane vertical distribution, the solvent that will be used for wash-out is put in solvent groove (7), chromatograph paper (2) upper end is immersed in the solvent groove (7), and sample to be separated puts on the chromatograph paper center line or suitable position by feeder (1).Iontophoretic electrode (5) is clamped chromatograph paper (2), and electrode is fixing by support (3).Chromatograph paper feather edge vandyked, each tip is provided with a gatherer (6), collects different components.Can be in feeder (1) application of sample and from gatherer (6), take the material of separation continuously away continuously, realize separating continuously.The volatilization degree of looking used solvent determines whether and whole device need be arranged in the airtight case, makes its balance of steam.When making solvent, adopt airtight casing (4) with organic solvent; When making solvent, adopt open system with the aqueous solution.Wherein sample introduction speed and material composition number, institute's making alive, chromatograph paper width all has relation.For width is 30 centimetres chromatograph paper, and institute's making alive is generally 1～10 volt/centimetre.When 5 of number of components are following, sample size 10～50 ml/min; When 5 of number of components are above, sample size 1～10 ml/min.Simultaneously, the sawtooth number of chromatograph paper feather edge what, also relevant with separative efficiency, general sawtooth number can be consistent with number of components or more than number of components.The width of chromatograph paper influences separative efficiency equally, and the width of chromatograph paper increases and widens along with number of components, and the width of every component must satisfy the requirement of voltage after the width widen between 1～3 centimetre.
When being backing material with chromatograph silica gel (8), when in the casing of making by insulating materials (4), being symmetrical arranged a pair of iontophoretic electrode (5), be full of chromatograph silica gel (8) in the casing (4), bottom half evenly is divided into some grids (9), every grid element center has an osculum (10), each osculum is divided into a gatherer (6), material to be separated is added in casing (4) upper end by feeder (1), wherein not charged particle will obtain in interceptor(-ter), different electrical charged particles obtain in the gatherer near the opposite electrode plate, and its controlled condition is identical during with the papery backing material.
When being backing material with chromatograph silica gel (8), when in the casing of making by insulating materials (4), being symmetrical arranged two pairs of iontophoretic electrodes (5), be full of chromatograph silica gel (8) in the casing (4), bottom half evenly is divided into some grids (9), every grid element center has an osculum (10), each osculum is divided into a gatherer (6), material to be separated is added in casing (4) upper end by feeder (1), wherein not charged particle will obtain in interceptor(-ter), different electrical charged particles obtain in the gatherer near the opposite electrode plate, its controlled condition is identical during with the papery backing material, but its separating effect is excellent during than pair of electrodes.
The effect that the present invention can reach is:
1. the continuous Separation ﹠ Purification of micro-bioactivator (enzyme, hormone, albumen, DNA, RNA, plasmid etc.), for difficult separate substance, the two poles of the earth or multipolely separate continuously of can connecting are up to reaching the expection separation of level.
2. the amino acid whose recovery of large-scale production or by-product can selectively separate 18 seed amino acids step by step.
3. the processing of inorganic salts waste water, with the yin, yang ion migration of inorganic salts to electrode surface, at electrode surface generating electrodes reaction or precipitating metal (negative electrode) or be oxidized to other material (anode), thereby they are removed from waste water, the method can be used electroplating industry, inorganic chemicals industry, organic synthesis industry, desalinization etc.
Above-mentioned three kinds of separation equipments can be composed in series multi-stage separation, to satisfy various separation requirement.
