Description

Raffinate separator

Technical field

This utility model relates to phosphoric acid solvent extraction technology field, especially a kind of raffinate separator.

Background technology

Phosphoric acid by wet process solvent extraction, is converted into PHOSPHORIC ACID TECH.GRADE by the 70%P2O5 in phosphoric acid by wet process, separately the phosphoric acid of impure higher 30%P2O5 concentrated after be used for producing high concentration phosphate fertilizer, the phosphoric acid of the impure higher 30%P2O5 of this part is called for short raffinate. Containing a certain amount of organic facies (extractant) in raffinate, after raffinate enters Phosphoric Acid Concentration system, elastomeric material can be reacted by extractant, etching apparatus, it is therefore necessary to the organic facies in raffinate is removed.

Now, about 30% raffinate that phosphoric acid by wet process solvent extraction obtains passes through natural subsidence groove natural subsidence, difference according to organic facies and aqueous phase proportion, organic facies swims in trough upper strata, lower layer of water is mutually by being pumped into Phosphoric Acid Concentration system, but after simple subsider natural subsidence, subsider upper organic phase can not be drained in time, organic facies can be caused to bring in aqueous phase when liquid level is low, hence into Phosphoric Acid Concentration system, it is all adopt line with rubber anticorrosion because of Phosphoric Acid Concentration system, it is easy to corrosion rubber.

Utility model content

This utility model provides following technical scheme: raffinate separator, including cell body, is provided with a guide shell inside described cell body, and the lower part outlet of this guide shell is positioned at the bottom of cell body, the top inlet connection feed pipe of guide shell; The border, top of described cell body is provided with a downflow weir, and ringwise, the side top of cell body is provided with an organic phase outlet pipe to this downflow weir entirety, and the height of this organic phase outlet pipe is lower than downflow weir; The bottom of described cell body is provided with an aqueous phase outlet.

As further scheme of the present utility model: described feed pipe connects raffinate storage tank.

As further scheme of the present utility model: described organic phase outlet pipe connects with organic facies storage tank.

As further scheme of the present utility model: described aqueous phase outlet connects with separating rear raffinate storage tank, and after separation, raffinate storage tank is connected with Phosphoric Acid Concentration system by delivery pump.

Compared with prior art, the beneficial effects of the utility model are: this raffinate separator has the advantage that one, simple in construction, if a guide shell, sends into bottom cell body by guide shell by material, flows out, it is achieved the stationary stream state of liquid bottom guide shell; Two, cell body border, top be provided with a downflow weir, through natural subsidence, the difference according to material proportion, organic facies enters downflow weir, it is achieved well sharp separation, quickly takes away.

Organic facies in raffinate is efficiently separated by this utility model, and organic facies is recycled, thus reducing the loss of organic facies, save production cost, and ensure that the raffinate dephosphorization acid concentration systems after separating is without organic facies, does not corrode rubber equipment, is worth promoting.

Detailed description of the invention

Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is clearly and completely described, it is clear that described embodiment is only a part of embodiment of this utility model, rather than whole embodiments. Based on the embodiment in this utility model, the every other embodiment that those of ordinary skill in the art obtain under not making creative work premise, broadly fall into the scope of this utility model protection.

Refer to Fig. 1-3, in this utility model embodiment, raffinate separator, including cell body 1, described cell body 1 is internal is provided with a guide shell 2, and the lower part outlet of this guide shell 2 is positioned at the bottom of cell body 1, the top inlet connection feed pipe 3 of guide shell 2, feed pipe 3 connects raffinate storage tank; The border, top of described cell body 1 is provided with a downflow weir 4, this downflow weir 4 entirety is ringwise, the side top of cell body 1 is provided with an organic phase outlet pipe 5, the height of this organic phase outlet pipe 5 is lower than downflow weir 4, organic facies can be discharged, this organic phase outlet pipe 5 connects with organic facies storage tank, organic facies is delivered to organic facies storage tank and stores; The bottom of described cell body 1 is provided with an aqueous phase outlet 6, this aqueous phase outlet 6 is used for the aqueous phase after discharging sedimentation, aqueous phase outlet 6 connects with separating rear raffinate storage tank, after separation, raffinate storage tank is connected with Phosphoric Acid Concentration system by delivery pump, is undertaken concentrating or directly preparing other phosphate product by water conveying to Phosphoric Acid Concentration system.

Operation principle of the present utility model: feed pipe 3 is by guide shell 2 to feeding in cell body 1, and after sedimentation, organic facies is overflowed from downflow weir 4, discharges via organic phase outlet pipe 5, and aqueous phase is discharged via bottom aqueous phase outlet 6.

Construction features of the present utility model and advantage thereof: one, simple in construction, if a guide shell 2, send into bottom cell body 1 by guide shell 2 by material, flows out, it is achieved the stationary stream state of liquid bottom guide shell 2;

Two, cell body 1 border, top be provided with a downflow weir 4, through natural subsidence, the difference according to material proportion, organic facies enters downflow weir 4, it is achieved well sharp separation, quickly takes away.

It is obvious to a person skilled in the art that this utility model is not limited to the details of above-mentioned one exemplary embodiment, and when without departing substantially from spirit of the present utility model or basic feature, it is possible to realize this utility model in other specific forms.
