Abstract
The utility model belongs to the device for metallurgy separation in a wet method, in particular relates to an ion exchanging device, which comprises a densification moving bed absorption tower and a fixing bed ion exchanging tower, wherein a saturated resin outlet of the densification moving bed absorption tower is connected with an inlet on the top part of a plurality of fixing bed ion exchanging towers which are arranged in parallel, and two adjacent fixing bed ion exchanging towers are serially connected with each other, and a poor resin E outlet of each fixing bed ion exchanging tower is connected with a poor resin inlet of the densification moving bed absorption tower. The ion exchanging device has less fixed investment, and reduces the investment of the resin, and has compact process and structure and simple operation.
Description
Technical field
The utility model belongs to a kind of ion-exchange unit, is specifically related to a kind of ion-exchange unit that hydrometallurgy is separated that is used for.
Background technology
At present, the ion-exchange unit of widespread usage is mainly ADSORPTION IN A FIXED BED-fixed bed drip washing or packed moving bed absorption-packed moving bed drip washing equipment, above-mentioned ion-exchange unit has been represented the advance of domestic hydrometallurgical extraction separating technology, automaticity is higher, labour intensity is lower, and has realized the requirement of environmental protection, cleaner production.
But the said equipment need adopt pressure to carry the resin measuring tank, and number fat input amount is big, and investment is big, and it is many to take the factory site, makes this structure and complex process.
The utility model content
The purpose of this utility model is to provide a kind of fixed investment few, and the resin input amount is few, process structure compactness, ion-exchange unit simple to operate.
Realize the technical scheme of the utility model purpose: a kind of ion-exchange unit, it comprises packed moving bed adsorption tower and fixed bed ion exchange tower, wherein, the outlet of packed moving bed adsorption tower saturated resin is connected with several fixed bed ion-exchange top of tower inlets side by side, connect between two adjacent fixed bed ion exchange towers, the poor resin E outlet of each fixed bed ion exchange tower is connected with the poor resin inlet of packed moving bed adsorption tower.
The quantity of described fixed bed ion exchange tower is 2～6.
Useful technique effect of the present utility model: when the utility model designs, the volume of all fixed bed ion exchange towers is slightly larger than or equals the volume that the packed moving bed adsorption tower discharges saturated resin at every turn, can realize quick drip washing like this, turn back to the poor resin after the drip washing in the packed moving bed ion exchange tower recycling in time, improved the turnover rate of resin, thereby greatly reducing the input amount of expensive resin, the input amount of expensive resin can reduce by 20%～80%.Compare conventional fixed bed ion exchange tower, the volume of the utility model fixed bed eluting column has reduced to have reduced equipment investment more than 60%.The fixed bed ion exchange tower itself is an eluting column, it is again the pressure transfer pot, be again the resin measuring tank simultaneously, a tower three usefulness have been realized, saved in the past ion-exchange unit each tower of domestic widespread usage and all must carry the resin measuring tank by a supporting pressure, not only greatly reduced investment outlay, and saved and take the factory site, make this process structure compactness, simple to operate.
Description of drawings
Fig. 1 is the structural representation of a kind of ion-exchange unit provided by the utility model.
Among the figure: 1. packed moving bed adsorption tower; 2. the first fixed bed ion exchange tower; A. the solution that contains valuable metal; B. saturated resin; C. leacheate; D. valuable metal pregnant solution; E. poor resin; F. valuable metal adsorbs the back tail washings.
The specific embodiment
Below in conjunction with drawings and Examples a kind of ion-exchange unit provided by the utility model is described in further detail.
As shown in Figure 1, a kind of ion-exchange unit, it comprises packed moving bed adsorption tower 1 and fixed bed ion exchange tower 2, wherein, the outlet of packed moving bed adsorption tower 1 saturated resin B is connected with several fixed bed ion exchange tower 2 tops inlets side by side, series connection between two adjacent fixed bed ion exchange towers 2, the poor resin E outlet of each fixed bed ion exchange tower 2 is connected with the poor resin inlet of packed moving bed adsorption tower 1.The quantity of described fixed bed ion exchange tower 2 can be 2～6.
Operation principle of the present utility model: what packed moving bed was inhaled 1 attached employing is bottom feed liquor mode, the control liquid inventory is kept resinbed in the tower, and to be closely knit suspended state be piston-like, the solution A that contains valuable metal enters from the bottom of packed moving bed ion exchange tower 1, behind the resinbed in the tower, valuable metal is adsorbed on the resin, and its valuable metal absorption back tail washings F discharges from the top of tower.The valuable metal concentration of element progressively reduces in resin bed from lower to upper in the tower, forms concentration gradient.The resin of bottom is saturated and upper resin is also leaked when passing valuable metal in the tower, regularly gives off the saturated resin B in bottom, makes it enter fixed bed ion exchange tower 2 and carries out drip washing and claim desorption and regeneration again.Poor resin E after the drip washing turns back in the packed moving bed ion exchange tower 1.The drip washing mode of fixed bed ion exchange tower 2 is that leacheate C is advanced at the top, and the solution that drip washing is got off is the enrichment solution D of valuable metal.This enrichment solution D can send to further processing, or precipitation or electrolysis.
The utility model can be applicable to: enrichment and recovery valuable metal from barren solution, and such as noble metal, platinum Family's metal, dissipated metal, radioactive element and rare earth element; Purifying compounds is similar with separating property Element is such as tantalum, niobium, zirconium, hafnium, rare earth element; Wastewater treatment; Softening water for industrial use and purifying life Water.
Claims (2)
1. ion-exchange unit, it comprises packed moving bed adsorption tower (1) and fixed bed ion exchange tower (2), it is characterized in that: the outlet of packed moving bed adsorption tower (1) saturated resin (B) is connected with several fixed bed ion exchange tower (2) top inlets side by side, series connection between two adjacent fixed bed ion exchange towers (2), the poor resin E outlet of each fixed bed ion exchange tower (2) is connected with the poor resin inlet of packed moving bed adsorption tower (1).
