Technical field
The utility model relates to production energy-saving field such as phosphorus composite fertilizer, S-based compound fertilizer, is specifically related to phosphorus composite fertilizer factory energy saver.
Background technology
In the prior art, the phosphoric acid heating concentrates with the liquefied ammonia evaporation and all consumes a large amount of fresh water steams, causes the water vapour demand excessive.In neutralizations such as phosphorus composite fertilizer and S-based compound fertilizer are produced, can produce 90～100 ℃ secondary steam, and directly be discharged in the atmosphere, cause a large amount of thermal waste contaminate environment simultaneously.
Summary of the invention
The purpose of the utility model just is to address the above problem, and a kind of phosphorus composite fertilizer factory energy saver is provided, and can not only heat concentrated phosphoric acid, evaporation liquefied ammonia, can also energy efficient, reduce in and discharge of steam.
To achieve these goals, the technical scheme of the utility model employing is:
A kind of phosphorus composite fertilizer factory energy saver; Comprise phosphoric acid well heater, liquefied ammonia vaporizer and vacuum system; It is characterized in that: export and condensate outlet E with steam-in, cold phosphoric acid inlet, Low Temperature Steam outlet A, hot phosphoric acid during described phosphoric acid well heater comprises; Described liquefied ammonia vaporizer comprises Low Temperature Steam inlet, liquefied ammonia inlet, Low Temperature Steam outlet C, gas ammonia outlet and condensate outlet F; Described phosphoric acid well heater is connected through Low Temperature Steam pipeline B with the liquefied ammonia vaporizer, and the Low Temperature Steam outlet C of described liquefied ammonia vaporizer is connected with vacuum system through Low Temperature Steam pipeline D.
Described phosphoric acid heater base is provided with propeller pump.
The advantage of the utility model is: 1, the utility model apparatus structure is simple, and the steam heating concentrated phosphoric acid and evaporation liquefied ammonia that can utilize neutralization reaction to produce are practiced thrift a large amount of live steams; 2, reduce vacuum system load, saves energy; 3, reduce secondary steam quantity discharged and reduce its exhaust temperature, help environment protection.
Description of drawings
Fig. 1 is the utility model setting drawing.
Among Fig. 11, the phosphoric acid well heater, 2, the liquefied ammonia vaporizer, 3, propeller pump, 4, in and the steam-in; 5, cold phosphoric acid inlet, 6, Low Temperature Steam outlet A, 7, the outlet of hot phosphoric acid, 8, condensate outlet E; 9, Low Temperature Steam pipeline B, 10, Low Temperature Steam inlet, 11, the liquefied ammonia inlet, 12, Low Temperature Steam outlet C; 13, gas ammonia outlet, 14, condensate outlet F, 15, Low Temperature Steam pipeline D, 16, vacuum system.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is further specified.
As shown in Figure 1; A kind of phosphorus composite fertilizer factory energy saver; Comprise phosphoric acid well heater 1, liquefied ammonia vaporizer 2 and vacuum system 16; During comprising, described phosphoric acid well heater 1 exports A6, the outlet 7 of hot phosphoric acid and condensate outlet E8 with steam-in 4, cold phosphoric acid inlet 5, Low Temperature Steam; Described liquefied ammonia vaporizer 2 comprises Low Temperature Steam inlet 10, liquefied ammonia inlet 11, Low Temperature Steam outlet C12, gas ammonia outlet 13 and condensate outlet F14, and described phosphoric acid well heater 1 is connected through Low Temperature Steam pipeline B9 with liquefied ammonia vaporizer 2, and the Low Temperature Steam outlet C12 of described liquefied ammonia vaporizer 2 is connected with vacuum system 16 through Low Temperature Steam pipeline D15.
Described phosphoric acid well heater 1 bottom is provided with propeller pump 3.
This device operation steps is:
From neutral steam; Temperature is about 90 ℃; Get into phosphoric acid well heaters 1 heating concentrated phosphoric acid with steam-in 4 in the warp, the propeller pump 3 of phosphoric acid well heater 1 bottom makes phosphoric acid at phosphoric acid well heater 1 internal circulation heat-exchanging, and the hot phosphoric acid after heating is concentrated gets into next workshop section through hot phosphoric acid outlet 7; The low temperature secondary steam of heating evaporation gets into liquefied ammonia vaporizer 2 evaporation liquefied ammonia after Low Temperature Steam outlet A gets into Low Temperature Steam pipeline B, in the steam heat release after the phlegma that forms discharge through condensate outlet E8.
Low temperature secondary steam from Low Temperature Steam pipeline B gets into liquefied ammonia vaporizer 2 through Low Temperature Steam inlet 10; Vacuum system 16 is connected with liquefied ammonia vaporizer 2 through Low Temperature Steam pipeline D15; And then the secondary Low Temperature Steam that the vacuum tightness of control phosphoric acid well heater 1 makes phosphoric acid heating back generation temperature be about 70 ℃ is used for the liquefied ammonia evaporation; Forming phlegma behind the evaporation of the low temperature secondary steam heat release simultaneously liquefied ammonia discharges through condensate outlet F14; The phlegma that produces helps reducing the vacuum tightness of phosphoric acid well heater, has therefore reduced the load of vacuum system, saves energy; Liquefied ammonia gets into liquefied ammonia vaporizer 2 through liquefied ammonia inlet 11, and the gas ammonia that behind heating evaporation, produces gets into next workshop section through gas ammonia outlet 13, and so far process is accomplished.
