Description
Technical field
The utility model relates to phosphoric acid by wet process manufacturing technology field, particularly relates to a kind of mixing tee for the production of phosphoric acid by wet process.
Background technology
Phosphoric acid is a kind of important intermediate chemicals, and its purposes has summed up two aspects, i.e. the production of fertiliser production and industrial phosphoric acid salt, and phosphoric acid by wet process is then mainly for the production of fertilizer.Produce the amount of heat can released in the reaction process of phosphoric acid by wet process with sulfuric acid, when heat can not be removed, it is enough to the boiling state making slurry temperature rise to about 150 DEG C, thus device can not normally be produced, operating conditions worsens, and equipment corrosion is serious, brings disadvantageous effect to production.
In traditional wet method thing production process of phosphoric acid, sulfuric acid generally directly adds in reactive tank, easily there is mixing uneven phenomenon in such sulfuric acid and rephosphorization acid, thus the heat of dilution of sulfuric acid causes reactive tank local temperature too high, and then damage reaction cell wall and top cover, phosphogypsum crystal weak effect, technic index can not steadily control, and production cannot be carried out.
Utility model content
The utility model mainly solves technical problem existing in prior art, thus provides a kind of mixing tee for the production of phosphoric acid by wet process diluting evenly, there will not be local temperature too high.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
The mixing tee for the production of phosphoric acid by wet process that the utility model provides, this mixing tee is arranged in reactive tank, described reactive tank comprises the first to the 9th district set gradually, this mixing tee is positioned at second of described reactive tank, in 3rd district, and it is vertical through described second, the top cover in 3rd district, the lower surface of described top cover is provided with line with rubber preservative coat, this mixing tee comprises the sulfuric acid feed-pipe be interconnected, rephosphorization acid feed-pipe and dilution tube, described rephosphorization acid feed-pipe tilts upward setting, described dilution tube is arranged on described second, more than the liquid level in 3rd district, and the lower circumference sidewall of described dilution tube is provided with multiple first through hole, and also comprise a snubber assembly, described snubber assembly is arranged on the top of described first through hole, and be positioned at the below of described rephosphorization acid feed-pipe.
Further, described snubber assembly comprises horizontally disposed dash plate, and described dash plate is provided with multiple second through hole.
Further, the angle of described rephosphorization acid feed-pipe and horizontal plane is 10-20 degree.
Further, multiple described first through hole is distributed on the lower circumference sidewall of described dilution tube.
Further, described sulfuric acid feed-pipe, rephosphorization acid feed-pipe and dilution tube adopt that 904L is stainless steel welded forms, and described stainless surfaces externally and internally is all lined with polytetrafluoroethylmaterial material.
The beneficial effects of the utility model are: by adding the rephosphorization acid of the vitriol oil and 15-18% in sulfuric acid feed-pipe and rephosphorization acid feed-pipe respectively simultaneously, sulfuric acid and rephosphorization acid are in dilution tube after preliminary mixed diluting, react in second and third district that multiple first through hole flows into reactive tank uniformly again, which obviate sulfuric acid and rephosphorization acid directly adds reactive tank, because mixing the too high phenomenon of reactive tank local temperature that inequality causes, simultaneously, by arranging snubber assembly, slow down surging force when rephosphorization acid and sulfuric acid mixing further, avoid the rapid expansion of heat.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the structural representation of the mixing tee for the production of phosphoric acid by wet process of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail, to make advantage of the present utility model and feature can be easier to be readily appreciated by one skilled in the art, thus more explicit defining is made to protection domain of the present utility model.
Consult shown in Fig. 1, mixing tee for the production of phosphoric acid by wet process of the present utility model, this mixing tee is arranged in reactive tank 1, reactive tank 1 comprises the first to the 9th district set gradually, this mixing tee is positioned at second of reactive tank 1, in 3rd district, and it is vertical through second, the top cover 9 in 3rd district, the lower surface of top cover 9 is provided with line with rubber preservative coat 8, this mixing tee comprises the sulfuric acid feed-pipe 2 be interconnected, rephosphorization acid feed-pipe 3 and dilution tube 4, rephosphorization acid feed-pipe 3 tilts upward setting, dilution tube 4 is arranged on second, more than the liquid level in 3rd district (preferred, dilution tube 4 is arranged on second, more than the liquid level 20cm in 3rd district), and the lower circumference sidewall of dilution tube 4 is provided with multiple first through hole 5, and also comprise a snubber assembly, snubber assembly is arranged on the top of the first through hole 5, and be positioned at the below of rephosphorization acid feed-pipe 3.The utility model by adding the rephosphorization acid of sulfuric acid and 15-18% respectively simultaneously in sulfuric acid feed-pipe 2 and rephosphorization acid feed-pipe 3, sulfuric acid and rephosphorization acid are in dilution tube 4 after preliminary mixed diluting, react in second and third subregion that multiple first through hole 5 flows into reactive tank 1 uniformly again, which obviate sulfuric acid and rephosphorization acid directly adds reactive tank 1, because mixing the too high phenomenon of reactive tank 1 local temperature that inequality causes.
Concrete, snubber assembly comprises horizontally disposed dash plate 6, and dash plate 6 is provided with multiple second through hole 7.By sulfuric acid and rephosphorization acid after dash plate 6 cushions, then flow in dilution tube 4 through the second through hole 7, it slow down surging force when rephosphorization acid and sulfuric acid mix, and avoids the rapid expansion of heat.Meanwhile, snubber assembly also serves pre-mixing effect to sulfuric acid and rephosphorization acid.
Preferably, conveniently rephosphorization acid flows in rephosphorization acid feed-pipe 3, and rephosphorization acid feed-pipe 3 and the angle of horizontal plane are 10-20 degree (also can be other proper angle).And in order to make the mixed solution of sulfuric acid and rephosphorization acid flow out uniformly, multiple first through hole 5 is distributed on the lower circumference sidewall of dilution tube 4.
In the utility model, sulfuric acid feed-pipe 2, rephosphorization acid feed-pipe 3 and dilution tube 4 adopt that 904L is stainless steel welded to be formed, and stainless surfaces externally and internally is all lined with polytetrafluoroethylmaterial material.
Above, be only embodiment of the present utility model, but protection domain of the present utility model is not limited thereto, any change of expecting without creative work or replacement, all should be encompassed within protection domain of the present utility model.Therefore, the protection domain that protection domain of the present utility model should limit with claims is as the criterion.
