Description
Technical field
The utility model relates to a kind of ion-exchange unit, belong to the packed moving bed eluting column, also can do full tower and tower transition washed, can be widely used in the hydrometallurgy industry, for example: the extraction of gallium and uranium and recovery particularly relate to a kind of eluting column of packed moving bed.
Technical background
Gallium is to be used to one of main raw material of producing semiconductor material, is to make the most basic functional materials of opto-electronic device, as gallium arsenide, gallium phosphide, gan etc.Gallium is a dissipated metal, because China's gallium resource is very abundant, the production potential of China's gallium is bigger in the world, domestic competition is the fierceness of ten minutes also, current, manufacturer both domestic and external has recognized that all having only with ion exchange method of technico-economical comparison advanced person reclaimed gallium from Bayer-process seed-separating mother liquor (hereinafter to be referred as the absorption mother liquor) in all multi-methods of producing gallium, therefore, each manufacturer all strengthens research and drops on the method for ion-exchange production gallium and on the equipment, constantly improve, to reach the purpose of low-cost high production.
The drip washing that utilizes the ion-exchange packed moving bed from the alumina producing flow process, to reclaim gallium, full wash with transformation process on producing, be difficult.Its difficulty is that cloth liquid must be evenly.Because what liquid phase adopted is the mode of low in and high out, promptly liquid distributor enters the tower at the bottom of the tower, flow out from the liquid outlet tank of cat head, owing to the difference of the compaction rate of resin in tower causes resistance difference to eluent, eluent is easy to form bias current in tower, owing to action of gravity, eluent is easy to form partial mixed flow in tower again.So, cloth liquid must be evenly, each point of cross section upwards pressure equal substantially with flow at the bottom of requiring tower, only in this way just may make the solid-liquid two-phase in tower, constitute a full counter current ion exchange process of ideal, make the efficient of tower higher, thereby the raising washout rate improves production capacity, reduces cost.
The utility model content
Technical problem to be solved in the utility model is: overcome the deficiencies in the prior art, provide a kind of simple in structure, cost is lower, cloth liquid is even, elution efficiency is high, the production run eluting column of ion-exchange packed moving bed stably.
The technical solution of the utility model is:
A kind of eluting column of packed moving bed, contain tower body, described tower body upper end is provided with into pitch tube, its lower end is provided with puts the resin mouth, described tower body top and middle part are respectively arranged with liquid outlet tank and overflow liquid bath, and the same plane of described tower body bottom is provided with some following liquid-inlet pipes, and described liquid-inlet pipe parallel equidistant is formed liquid distributor side by side, and be provided with some fluid apertures on the liquid-inlet pipe under each is described, all are liquid-inlet pipe while feed liquor down.
The center of circle of all the fluid apertures on each described liquid-inlet pipe down lays respectively on the axial straight line of liquid-inlet pipe tube wall under two edges, and axially adjacent fluid aperture is on same straight line, the plane that the circle central axis of two straight lines and following liquid-inlet pipe forms be respectively 45 degree and 135 by the angle of the same side horizontal plane of the circle central axis of liquid-inlet pipe down and spend.
Article two, the perforate direction of the described fluid aperture on the straight line be oblique down, the fluid column direction of adjacent fluid aperture fluid is respectively 45 degree and 135 with same horizontal angle by the center of circle on the liquid-inlet pipe cross section down and spends.
The edge, aperture of the fluid aperture on the described same straight line is liquid-inlet pipe axially diminished to the feed liquor far-end by the feed liquor near-end gradually down, and the varying aperture scope is 1.2-2.5mm.
Principle of work of the present utility model is as follows: eluent is uniform by at the bottom of the some uniform following liquid-inlet pipes of parallel equidistant enter tower on the same cross section, tower body bottom on the direction perpendicular to following liquid-inlet pipe; The aperture of the different fluid apertures of every following liquid-inlet pipe changes, its edge, aperture liquid-inlet pipe is down diminished to the feed liquor far-end gradually by the feed liquor near-end, meet the distribution rule of hydromeehanics, reached along the following liquid-inlet pipe direction also even purpose of fluid and dispense pressure at ducted pressure and flow.Add all ejections downwards of eluent, pressure by the reflection uniformly of tower wall at the bottom of the tower of tower body upwards, at the bottom of tower, form an invisible uniform band setting-out bed course, the uniform pressure distribution of water subfill is on the same cross section of tower body, and direction upwards, and this makes that eluent can make progress uniformly in tower body mobile.
In whole lessivation, eluent upwards is in the form of piston at the bottom of by tower uniformly and flows, and resin is even piston-type downwards by cat head and moves, and the solid-liquid two-phase has constituted a full counter current ion exchange process of ideal in tower.
The beneficial effects of the utility model are:
The utlity model has simple in structure, low cost of manufacture, advantage such as cloth liquid is even, elution efficiency is high, production run is steady, it can be widely used in the hydrometallurgy industry, for example: the extraction of gallium and uranium and recovery.The utility model can use the drip washing in ion-exchange, full wash and the operation that makes the transition on.
