Multifunction combined ion exchange resin column
Technical field
The utility model relates to a kind of ion-exchange unit, in particular, relates to a kind of multifunction combined ion exchange resin column.
Background technology
Ion exchange resin is with functional group's (namely having the active group of exchange ion), has network structure, insoluble macromolecular compound, normally spheric granules thing.Ion exchange resin, because of its good adsorptivity, is widely used in water treatment field, food processing field, pharmaceutical field, field of environment protection and synthetic chemistry and petro chemical industry field.The application process of ion exchange resin has the three kinds of technological processes of fixed bed process, mobile bed process and fluidized bed process usually, and wherein, fixed bed process (i.e. pillar absorption exchange process) is simple to operate, and practical value is large, and what use in testing machine industrial production is the most frequent.
Existing ion exchange resin column is made up of ion-exchange housing and inner resin of filling, inner resin of filling is supported by the sieve plate of ion exchange column housing inner bottom part, ion exchange column housing is the cylindrical tube of hollow, sealed bottom also leaves discharging opening, and top is provided with charging aperture dome.During use, all resin successions are all filled in ion exchange column housing, then by the dome fastening at top.Injected from top charging aperture by material liquid, resin does not move in exchange column, and material liquid relies on gravity to flow through resin bed downwards in post again, and absorption exchange occurs, and the liquid after exchange is finally discharged from bottom discharge mouth.
In the practical application of existing ion exchange resin column, material liquid is only directly entered in ion exchange resin column by top charging aperture, the flowing of material liquid in resin bed is not uniform plug flow, and there is the phenomenons such as channel, bias current and wall stream, this will cause separative efficiency to decline.And, when material liquid impurity is more when resin particle is too small, the gap between resin particle may be caused blocked, time serious, can cause material liquid cannot be dirty.Now, ensure material liquid proper flow, the resin disposable filling must entered all is poured out and could be processed, and this can affect whole test and production process.
Meanwhile, existing ion exchange resin column be a certain proportion of cationic, anionic exchange resin is loaded in mixture fill in same switching equipment substantially, the ion in fluid is exchanged, is removed; Cationic, anionic exchange resin number in same ion exchange resin column is certain, or cationic, anionic exchange resin is filling with certain proportion, or be all that cationic ion-exchange resin is filling, or be all that anion exchange resin is filling, to be adapted to the absorption of different material liquids.There is no a kind of ion exchange resin column can changing inner ion exchanger resin at any time, realize the absorption that same ion exchange resin column can carry out highly acid material liquid, the absorption of strong basicity material liquid can be carried out again.
