Description
Technical field
The utility model relates to a kind of single hose reactor drum, relates in particular to a kind of single hose reactor drum of production diammonium phosphate.
Background technology
China some areas (like Yichang) phosphorus ore grade is low; Foreign matter content is high; After ore dressing; Foreign matter content is still higher when the production diammonium phosphate, how to use the low phosphorus ore of grade such as ore deposit, Yichang to produce the fine diammonium phosphate, and to reach internal class product level be a difficult problem of pendulum in face of ours.
At present can use Yi Changkuang to produce the fine diammonium phosphate, but because of the fluctuation of ore deposit foreign matter content, its quality control is unstable, and is bad during fashion through technological improvement utilization hybrid technique.For stablizing the product appearance quality of diammonium phosphate, existing plan comes the production diammonium phosphate through research and development utilization single hose reactor drum.
Traditional single hose reactor drum is stricter than groove type reactor to the requirement of phosphoric acid quality; And the heat of reaction during the production diammonium phosphate in the tablets press is big; Need remove heat through strengthening air capacity; In addition, also there is effusion ammonia amount big (account for total ammonia amount 15%～20%), problem such as the exhaust scrubber load is big.
Summary of the invention
The purpose of the utility model is to provide a kind of single hose reactor drum that can utilize the phosphorus ore production high-quality diammonium phosphate that grade is low, foreign matter content is high, and solves the above-mentioned problems that exist when traditional single hose reactor drum is produced simultaneously.
The concrete technical scheme of the single hose reactor drum of a kind of production diammonium phosphate of the utility model is:
A kind of single hose reactor drum of production diammonium phosphate; Comprise phosphoric acid inlet pipe, liquefied ammonia inlet pipe, reaction tubes, first nozzle and second nozzle; Phosphoric acid inlet pipe and liquefied ammonia inlet pipe are arranged on the end of reaction tubes; First nozzle and second nozzle are arranged on the sidewall of reaction tubes, and reaction tubes, first nozzle and second nozzle are straight pipe type, and the single hose reactor drum is obliquely installed the top at the tablets press discharge end.
Wherein, single hose reactor drum and tablets press discharge end are 3～10 ° angle of inclination.Be provided with the venturi tube conversion zone in the reaction tubes.
The single hose reactor drum of the production diammonium phosphate of the utility model has solved the problem that traditional single hose reactor drum exists through be installed in tablets press discharge end top by certain angle of inclination (3～10 °); Change single hose reactor drum production diammonium phosphate and only improved output, the problem that does not improve the quality.
In addition,, solved the more phosphoric acid of foreign matter content and when reaction, be prone to fouling and serious blocking problem, improved the output and the quality of diammonium phosphate greatly through reform and innovation to the single hose reactor drum.Particularly present dilution day by day along with domestic phosphate rock resource; It uses the large-scale diammonium phosphate device product quality of hybrid technique that decline is in various degree all arranged; The single hose reactor drum of the utility model is strong to the flexibility of phosphorus ore quality, has obvious competitive advantages.

Fig. 2 is the side sectional view of diammonium phosphate tablets press that the single hose reactor drum of the utility model is installed.
Embodiment
In order better to understand purpose, structure and the function of the utility model,, the single hose reactor drum of a kind of production diammonium phosphate of the utility model is done further detailed description below in conjunction with accompanying drawing.
As shown in Figure 1, the single hose reactor drum of the production diammonium phosphate of the utility model comprises phosphoric acid inlet pipe 1, liquefied ammonia inlet pipe 2, reaction tubes 3, first nozzle 4 and second nozzle 5.Wherein, Phosphoric acid import 1 pipe and liquefied ammonia inlet pipe 2 are arranged on the end of reaction tubes 3; Phosphoric acid inlet pipe 1 links to each other with phosphoric acid storage tank (not shown); Be used for that phosphoric acid is input into reaction tubes 3 and carry out neutralization reaction, liquefied ammonia inlet pipe 2 links to each other with the liquid ammonia storage tank (not shown), is used for liquefied ammonia is input into reaction tubes 3 and phosphatase reaction.
The sidewall of reaction tubes 3 is provided with first nozzle 4 and second nozzle 5; The phosphor ammonium slurry that phosphoric acid in the reaction tubes 3 and liquefied ammonia carry out generating after the neutralization reaction can be ejected in the tablets press through first nozzle 4 and second nozzle 5, to carry out the subsequent production process in the tablets press.First nozzle 4 in the utility model and the big I of second nozzle 5 are specifically set according to slip viscosity, atomizing effect and pressure etc.
In addition; The reaction tubes 3 in the single hose reactor drum of the production diammonium phosphate of the utility model and first nozzle 4 thereof and second nozzle 5 all are straight pipe type; And the single hose reactor drum of the utility model is installed in the top of tablets press discharge end with 3～10 ° angle of inclination; Thereby the heat of reaction that has solved traditional single hose reactor drum existence is big, effusion ammonia amount is many, the exhaust scrubber load heavily waits defective; Change traditional single hose reactor drum production diammonium phosphate and only improved output, the problem that does not improve the quality.
Fig. 1 and Fig. 2 are installed to the structural representation in the tablets press for the single hose reactor drum of the utility model; Wherein, The tablets press 6 preferred rotary drum granulators that adopt; And also can be provided with ammonia sparger 7 at first nozzle 4 of single hose reactor drum and the opening part of second nozzle 5, make that the phosphor ammonium slurry of ejection can carry out the secondary neutralization reaction with ammonia fully in tablets press from first nozzle 4 and second nozzle 5.Ammonia sparger 7 can adopt the structure formation of ammonia sparger commonly used in this area.
The production process of the diammonium phosphate of the single hose reactor drum of employing the utility model is:
SPA, is specially from phosphoric acid inlet pipe 1 entering reaction tubes 3 to tubular reactor through pump delivery after the tail system of washing absorbs ammonia, and liquefied ammonia then is transported in the reaction tubes 3 through liquefied ammonia inlet pipe 2 by liquid ammonia storage tank.Liquefied ammonia and phosphoric acid carry out neutralization reaction in reaction tubes 3, produce phosphor ammonium slurry.
Further, phosphor ammonium slurry sprays in the tablets press 6 through first nozzle 4 and second nozzle 5.The liquefied ammonia of phosphor ammonium slurry ejection in tablets press 6 and in the ammonia sparger 7 carries out the secondary neutralization reaction again, and carries out granulation.
Product after the granulation sieves and fragmentation after getting into the drying machine drying, and the qualified particle entering parcel tube after the screening wraps up, and the finished product behind the parcel is sent into and packed after cool off in the storehouse of loosing.
More than by specific embodiment the utility model is further described; But it should be understood that; Here concrete description; Should not be construed as the qualification to the essence and the scope of the utility model, the various modifications that the one of ordinary skilled in the art makes the foregoing description after reading this specification sheets all belong to the scope that the utility model is protected.
