Description
Technical field
The present invention relates to ion interchange unit, more particularly to a kind of slot type ion interchange unit and purposes.
Background technology
Ion exchange is a kind of important nonferrous metallurgy smelting technique, is widely used in the purification of metal and nonmetallic ion
And purification, it is a kind of unit operation for belonging to mass transfer separation process with the purpose for reaching extraction or removing some ions in solution.
Traditional fixed bed pillar ion-exchange unit, in actual moving process, due in liquid before friendship contain some foreign ions and
Solid particle, easily produces substantial amounts of crystalline particle in adsorption process, and partially crystallizable particles coat lives resin particle, direct shadow
The adsorption capacity and product quality of resin are rung, serious situation can cause distribution grid water cap or screen pack to be crystallized thing and block, make
Into absorption flow dramatic decrease, the normal operation of production is directly affected.
For crystalline particle caused by adsorption process, traditional fixed bed unit is difficult to be cleared up, and generally requiring will be complete
Portion's resin is dug out to eluriate, and needs to tear clear water cap or screen pack open, and whole process cycle is longer, and process is complex and the amount of labour
It is larger.
The content of the invention
It is an object of the invention to provide a kind of resin adsorption process that can preferably solve to produce crystalline particle problem
Slot type ion interchange unit.
To achieve the above object, the present invention provides a kind of slot type ion interchange unit, it is characterised in that including cell body
（11）, stirring vane（6）, microporous pipe（5）, be in charge of（12）, house steward（13）, filter（4）, residual cake valve（3）, scum pipe（2）, clear
Liquid valve（7）, clear liquid pipe（8）, recoil intake valve（9）, recoil air inlet pipe（10）；Wherein stirring vane（6）Positioned at cell body（11）
Centre, stirring vane（6）It is connected to cell body（11）Outer stirring motor（1）；Microporous pipe is distributed in cell body（11）Bottom；Cell body
（11）One side set gradually filter（4）, residual cake valve（3）And scum pipe（2）；In addition liquid valve is cleared while setting gradually（7）With
Clear liquid pipe（8）；It is described to be in charge of（12）Successively by adjacent microporous pipe（5）Connect, be in charge of（12）It is aggregated into house steward（13）,
House steward（13）With clearing liquid valve（7）It is joined directly together；In house steward（13）With clearing liquid valve（7）Between reconnect a pipe, on the pipe
Set gradually recoil intake valve（9）With recoil air inlet pipe（10）.
Further, the stirring vane（6）Height and the space be in charge of be 10-30 centimetres.
Further, the microporous pipe（5）Height be 10-40 centimetres.
Further, the microporous pipe（5）It is uniformly distributed in cell body（11）Bottom；
Optional, microporous pipe（5）Aperture ranges in 0.5-50 microns.
Further, it is described to be in charge of（12）A diameter of 50 millimeters, house steward（13）A diameter of 80-100 millimeters.
Further, filter（4）For 40-60 mesh.
The present invention also provides the purposes that the slot type ion interchange unit is used to remove crystalline particle in ion exchange process.
The present invention also provides slot type ion interchange unit described in application item and is used to remove crystalline particle in ion exchange process
Method, it is characterised in that
After the completion of ion-exchange reactions, opening clears liquid valve（7）, liquid after liquid after friendship or parsing is taken out using vacuum or pump
Go out, through clearing liquid pipe（8）Discharge outside groove, cell body（11）Interior resin and caused crystallization slag are by microporous pipe（5）Intercept in cell body
（11）It is interior；Cell body（11）Crystallization slag run up to it is a certain amount of after, that is, when clearing liquid speed degree and declining about half, be put into higher than stirring vane
About 40 centimetres of clean wash water, open stirring vane（6）, while open recoil intake valve（9）, use compressed air blowback microporous pipe
（5）The crystallization slag of outer wall and surrounding, 80% crystallization slag is set to enter in wash water；After wash water washing 30-60 minutes, residual cake valve is opened
（3）, wash water and crystallization slag pass through filter under the centrifugal action of stirring（4）Through scum pipe（2）Discharge outside groove, resin is by filter
（4）Intercept in groove.
Further, if the cell body crystallization quantity of slag is larger, following steps are repeated：It is put into dry higher than 40 centimetres of paddle agreement that contracts a film or TV play to an actor or actress
Washing water, open stirring vane（6）, while open recoil intake valve（9）, use compressed air blowback microporous pipe（5）Outer wall and week
The crystallization slag enclosed, most of crystallization slag is set to enter in wash water；After clean wash water washing 30-60 minutes, residual cake valve is opened（3）,
Wash water and crystallization slag pass through filter under the centrifugal action of stirring（4）Through scum pipe（2）Discharge outside groove, resin is by filter（4）Block
Cut in groove；Until outside more than 80% crystallization slag discharge system.
The present invention provides a kind of slot type ion interchange unit.The ion exchange cell body 11 is round cylinder, is pacified in the middle part of cell body
Stirring vane is filled, lower side is provided with a filtering filter 4, and filter 4 can intercept resin and discharge crystallization slag, cell body bottom
The multiple microporous pipes 5 of plane distribution, only clear liquid can be connected in parallel by microporous pipe 5, microporous pipe 5 by being in charge of 12, are respectively in charge of and worn
Cross after cell body that parallel connection collects for total discharging tube again.
In absorption or analysis state, residual cake valve 3 and clear liquid valve 7 and close, after the completion of ion exchange, opening clears
Liquid valve 7 is extracted out clear liquid by vacuum or pump；After crystallization slag accumulation arrives a certain amount of, running water or salt-free water washing are put into groove
Resin, closing clear liquid valve 7, open recoil intake valve 9, by the crystallization slag blowback of the outer wall of microporous pipe 5 and surrounding into washings,
Recoil after certain time, open residual cake valve 3, crystallization slag is discharged under the centrifugal action of stirring by filter 4 outside groove.If crystallization
The quantity of slag is larger, repeats washing, blowback, deslagging program, until 80% crystallization slag is cleared out outside groove.
Under stirring, crystallization slag is hardly formed to resin-coating effect, it is ensured that ion exchange is normally carried out；It is micro-
The filter area of hole pipe is much larger than traditional water cap and screen pack, and the height of microporous pipe 5 is 10-40 centimetres, and crystallization slag is difficult thorough
All filtering holes are blocked at bottom, and the cleaning frequency is relatively long；Air blowback and the centrifugal action of stirring, accelerate crystallization slag warp
Outside filter discharger, so as to efficiently quickly clean resin.
The aperture of filter need to select according to crystallization solid impurity particle size, be only applicable to resin particle size much larger than crystallization slag
The situation of particle size, the size dimension of filter need to according to the crystallization quantity of slag number select.Under normal circumstances, rosin size exists
More than 400 microns, the filter of 40-60 mesh can be selected below 100 microns in crystallization solid impurity particle size.The aperture ranges of microporous pipe
In 0.5-50 microns, can be selected according to the particle size of crystallization slag, precondition is to ensure that slag will not penetrate microporous pipe.
By the slot type ion interchange unit technique of the present embodiment, more than 80% crystallization slag can be all discharged to outside cell body.
The difficult problem excluded of crystalline particle is produced so as to solve resin adsorption process.
