Description
Technical field
Device for processing salt impurities in water in the actual a kind of NaOH production process of the utility model.
Background technology
Prepare in NaOH process at ionic membrane, adopt salt as primary raw material, salt adds in hot water with solid forms and turns to after saturated brine for ion-exchange membrane electrolyzer in process of production.Containing impurity such as calcium, magnesium, sulfate radical and silicon in crude salt, if a large amount of together the adding in production system with crude salt of these impurity, not only can have influence on the quality of final products, and ionic membrane can be caused to run, and power consumption rises, hydraulic performance decline even permanent damage.In industry employing sedimentation and filtration and chelating resin absorption method can by the Impurity removals such as calcium, magnesium ion in salt solution at present, but sila matter cannot be removed by the method in salt solution, and the increase of ion-exchange membrane facility running time thereupon, silicon builds up because removing in systems in which, produces bring very large harm to ionic membrane.
Utility model content
For there being the defect of technology on overcoming, the purpose of this utility model is intended to propose a kind ofly to carry out to salt solution the salt solution knot screen that secondary filter removes the impurity such as calcium, magnesium, silicon in the lump.
For achieving the above object, the utility model adopts following technical scheme:
A kind of salt solution knot screen, it is characterized in that: comprise turbine agitator, first stage precipitation tank, second-level settling pond, accurate filter and reservoir, described turbine agitator is arranged in first stage precipitation tank; Be provided with dividing plate and filter screen between described first stage precipitation tank and second-level settling pond, dividing plate is positioned on filter screen; The sidepiece of shown second-level settling pond has an aspirating hole; Described second-level settling pond is arranged with multiple accurate filter; The outlet of described accurate filter is connected in reservoir.
To the explanation of such scheme and scheme is as follows further:
1, in such scheme, described aspirating hole is connected with an air pump.
2, in such scheme, the bottom of described reservoir has an opening.
3, in such scheme, the water-supply-pipe that is provided with flow-stop valve after described opening, is connected with.
4, in such scheme, the corresponding accurate filter gating location of described second-level settling pond has discharging opening.
Because technique scheme is used, the utility model compared with prior art has following advantages:
The utility model is simple to operate, safe and reliable, have employed precise filtering device and the colloidal silica being difficult to filter can be made fully to be separated from salt solution, improve dust removal rate.Meanwhile, prepared highly purified refined brine practical for ionic membrane, reduce salt impurities in water and ionic membrane is run to the impact produced, extend ionic exchange membrane serve-time, has saved production cost greatly.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
In above accompanying drawing: 1, turbine agitator; 2, first stage precipitation tank; 3, second-level settling pond; 4, accurate filter; 5, reservoir; 6, dividing plate; 7, filter screen; 8, aspirating hole; 9, air pump; 10, opening; 11, water-supply-pipe; 12, flow-stop valve.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is further described:
Embodiment: shown in Figure 1:
A kind of salt solution knot screen, comprise turbine agitator 1, first stage precipitation tank 2, second-level settling pond 3, accurate filter 4 and reservoir 5, turbine agitator 1 is arranged in first stage precipitation tank 2, and the length of turbine agitator 1 can regulate, when dividing plate 6 between first stage precipitation tank 2 and second-level settling pond 3 and filter screen 7 are taken away, the extended length of turbine agitator 1, extends in second-level settling pond 3 and stirs; Be provided with dividing plate 6 and filter screen 7 between first stage precipitation tank 2 and second-level settling pond 3, dividing plate 6 is positioned on filter screen 7; The sidepiece of second-level settling pond 3 has an aspirating hole 8; Second-level settling pond 3 is arranged with multiple accurate filter 4; The outlet of accurate filter 4 is connected in reservoir 5.
Preferably, described aspirating hole 8 is connected with an air pump 9; The bottom of described reservoir 5 has an opening 10; The water-supply-pipe 11 that one is provided with flow-stop valve 12 is connected with after described opening 10.
When carrying out filtering-depositing, first poured in first stage precipitation tank 2 by saturated brine, add flocculant (in order to the calcium in saturated brine, magnesium ion are contained co-precipitation rapidly), open turbine stirrer 1 stirs.Stop stirring, leave standstill a period of time, take the dividing plate 6 between first stage precipitation tank 2 and second-level settling pond 3 away, open the air pump 9 that on second-level settling pond 3, aspirating hole 8 connects, accelerate to filter.This time filtration is only fallen by the sedimentation and filtration that the calcium in saturated brine, magnesium ion are formed, and the colloidal substance that silicon is formed in salt solution cannot be filtered in common Separation of Solid and Liquid.
After filtration terminates, take filter screen 7 away, regulate the length of turbine agitator 1, make it can extend in second-level settling pond 3 and stir.In second-level settling pond 3, secondary adds flocculant, and fully stir, because in the saturated brine after separation, other impurity are low, in abundant mixed salt solution, flocculant fully can act on colloidal silica, in and the electric charge of colloidal silica microparticle surfaces, repulsion between particulate is declined, and particles agglomerate becomes cotton-shaped, forms loose filamentary structure precipitation.After precipitation terminates, open the discharging opening of second-level settling pond 3, then by accurate filter 4 by sedimentation and filtration, reach and leach the clean object of Impurity removal in salt solution.
Place in reservoir 5 after saturated brine secondary filter completes, when needs carry out Electrolyzed Processing, open flow-stop valve 12, saturated brine is flowed in electrolytic cell by water-supply-pipe 11.
The utility model by secondary filter by clean for the Impurity removals such as the calcium in salt solution, magnesium, silicon, preventing the accumulation of silicon in brine system especially, reach the object of refined brine, is the raw material that ionic membrane manufacture is qualified, stabilizing ion film runs, and extends service life of ion-exchange membrane.
Above-described embodiment, only for technical conceive of the present utility model and feature are described, its object is to person skilled in the art can be understood content of the present utility model and implement according to this, can not limit protection domain of the present utility model with this.All equivalences done according to the utility model change or modify, and all should be encompassed within protection domain of the present utility model.
