Abstract
The utility model discloses a phosphoric acid filtrate treatment system, comprising a phosphoric acid pump (5), a membrane filter (7) and a phosphoric acid intermediate tank (9). The phosphoric acid filtrate treatment system is characterized in that a first pipeline on the input end of the phosphoric acid pump (5) is provided with a phosphoric acid settling tank (1), the lower end of the phosphoric acid settling tank (1) is connected to a slag acid tank (2) through a second pipeline (3), the bottom of the slag acid tank (2) enters the input end of a slag acid pump (11) through a third pipeline (10), the output end of the phosphoric acid pump (5) is connected to the upper end of the membrane filter (7) through a fourth pipeline (6), the lower end of the membrane filter (7) is connected to the phosphoric acid intermediate tank (9) through a fifth pipeline (8), and the phosphoric acid filtrate treatment system disclosed by the utility model has a simple structure and is improved in the production efficiency.
Description
Technical field
The utility model relates to a kind for the treatment of system of finished product phosphoric acid filter liquor.
Background technology
In recent years, phosphoric acid filter liquor is usually used to make monoammonium phosphate and solid phosphoric acid, the filtrate that is filtered the phosphoric acid of machine filtering separation adopts filtrate pump directly to send into phosphoric acid medial launder mostly, in actual production process, because the fluctuation of the solid content of finished product phosphoric acid can directly have influence on the production of monoammonium phosphate and phosphoric acid concentrated brought to certain difficulty, general when the solid content in phosphoric acid is greater than 2%, as follows on producing monoammonium phosphate impact: the physical appearance that affects product; Product nitrogen content can not improve, and available phosphorus reduces; Temperature of reaction is low, stops up shower nozzle, and granulation effect is bad, and affect phosphorus ammonium and produce, and for Phosphoric Acid Concentration: the cleaning of graphite heat exchanger, cleaning interval shorten, the working rate reduction of concentration systems; Phosphoric acid concentrate difficulty; The probability of line clogging increases etc.
Utility model content
In order to overcome the defect of above-mentioned prior art, a kind of phosphoric acid filter liquor treatment system that the utility model provides is simple in structure, enhance productivity.
In order to achieve the above object, the utility model is realized by following scheme, a kind of phosphoric acid filter liquor treatment system, comprise: phosphoric acid pump, film filter, phosphoric acid medial launder, it is characterized in that: phosphoric acid subsider of phosphoric acid pump input terminus the first install pipeline, phosphoric acid subsider lower end is connected to slag acid tank by second pipe, slag acid tank bottom enters into slag acid pump input terminus by the 3rd pipeline, phosphoric acid pump output terminal is connected to film filter upper end by the 4th pipeline, and film filter lower end is connected to phosphoric acid medial launder by the 5th pipeline.
The utility model can be found out in sum, when liquid phosphoric acid solution precipitates through peroxophosphoric acid subsider, solid in phosphoric acid solution is sunk to the bottom of phosphoric acid subsider and enters into slag acid tank by pipeline, reduced the solid content of phosphoric acid solution, slag acid solidliquid mixture in slag acid tank is discharged through past benzene and is got the processing of groove method through slag acid pump, the phosphoric acid solution that solid content is low after precipitation is through the work of peroxophosphoric acid pump, after filtering by film filter, enter phosphoric acid medial launder, this procedure structure is simple, easy to operate, raw materials quality and the production efficiency of this production link have been improved, Wei Xia road technique provides convenience.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Wherein: 1, phosphoric acid subsider; 2, slag acid tank; 3, second pipe; 4, the first pipeline; 5, phosphoric acid pump; 6, the 4th pipeline; 7, film filter; 8, the 5th pipeline; 9, phosphoric acid medial launder; 10, the 3rd pipeline; 11, slag acid pump.
Embodiment
As shown in the figure, a kind of phosphoric acid filter liquor treatment system, comprise: phosphoric acid pump 5, film filter 7, phosphoric acid medial launder 9, it is characterized in that: phosphoric acid pump 5 input terminus the first pipelines 4 arrange a phosphoric acid subsider 1, phosphoric acid subsider 1 lower end is connected to slag acid tank 2 by second pipe 3, slag acid tank 2 bottoms enter into slag acid pump 11 input terminuss by the 3rd pipeline 10, and phosphoric acid pump 5 output terminals are connected to film filter 7 upper ends by the 4th pipeline 6, and film filter 7 lower ends are connected to phosphoric acid medial launder 9 by the 5th pipeline 8.
The utility model is to implement like this, carry out successively following operation: solution enters phosphoric acid subsider 1, after sedimentation, the solution that solid content is large enters into slag acid tank 2 by second pipe 3, the large solution of solid content extracts recycling discharge by the 3rd pipeline 10 through slag acid pump 11 again, the little solution of solid content is extracted and is entered into film filter 7 by the phosphoric acid pump 5 on the right through the first pipeline 4, and solution enters into phosphoric acid medial launder 9 by the 5th pipeline 8 after film filter 7 filters.
By above embodiment, can find out, the utility model can improve phosphoric acid solution concentrating degree, effectively alleviates pipeline, shower nozzle obstruction, the feature of enhancing productivity.
Above embodiment is only in order to illustrate the utility model and the described technical scheme of unrestricted the utility model; Therefore, although this specification sheets has been described in detail the utility model with reference to each above-mentioned embodiment,, those of ordinary skill in the art should be appreciated that still and can modify or be equal to replacement the utility model; And all do not depart from technical scheme and the improvement thereof of spirit and scope of the present utility model, all should be encompassed in claim scope of the present utility model.
