Abstract
The utility model discloses a multi-effect concentrated liquor condensate drainage device. The lower portion of a heater after the second effect is provided with an opening and added with a liquor condensate drainage pipe and a liquor condensate drainage opening, and simultaneously, a valve is mounted on a portion close to the heater and used for adjusting opening. In the multi-effect concentrated liquor condensate drainage device, the opening of the liquor condensate drainage valve of the heater after the second effect is flexibly controlled, thereby smoothening drainage of liquor condensate, preventing a concentrating system of a first effect from building pressure, and effectively controlling temperature of a boiling point of slurry of the first effect. The multi-effect concentrated liquor condensate drainage device is extremely low in investment, and resolves the problem that concentrated slurry of the second effect is difficult to be fed to the first effect during slurry concentration-method monoammonium phosphate production. In addition, the multi-effect concentrated liquor condensate drainage device realizes continuous and stable production, increases system operation reliability, enhances operation flexibility, reduces operation difficulty, effectively increases capacity, and is applicable to a multi-phase-separated multi-effect concentrating and evaporating device.
Description
Technical field
The utility model relates to phosphate fertilizer, specifically, relates to the device that slurry concentrated process is produced the phosphorus ammonium.
Background technology
In and slurry concentrated process system phosphorus ammonium process be with containing P
2O
5About 18%～30% dilute phosphoric acid and ammonia react, by controlling the ammonium slip that degree of neutralization makes to be needed, slip concentrates through multiple-effect (being generally economic benefits and social benefits), after the slip process pressure exerting device pressurized spray drying after concentrating, obtains the powdery monoammonium phosphate product.Traditional I effect, II effect are all only with a condensate discharge pipe, and valveless.Because the secondary steam that II effectiveness I effect is evaporated is as thermal source, and secondary steam band foam, phlegma that I is imitated are unholiness, can cause II to imitate the local obstruction of well heater shell, both influence II and imitated concentrated effect, the secondary steam discharging that the I effect is evaporated is not smooth, I is imitated thickener and is built the pressure, and is to have the I of very big influence effect slip boiling temperature will be affected to dehumidification system and the control of product moisture content; Also can cause II to imitate slip and transport to I effect difficulty, production can not be continuous; The concentration systems hypertonia is brought many safety in production hidden danger simultaneously.
By retrieval, in Chinese patent literature, do not find relevant patent as yet.
Summary of the invention
It is a kind of simple in structure that the purpose of this utility model is to provide, and the spissated condensate discharge device of the multiple-effect of convenient operating maintenance solves condensate discharge problem smoothly.
In and slurry concentrated process system phosphorus ammonium system comprise that reactor, recycle pump, I imitate that evaporator room, I are imitated well heater, II is imitated evaporator room, II effect well heater, steam inlet pipe and secondary steam pipe, condensate discharge pipe, the spissated condensate discharge device of the multiple-effect that the designer provides is to imitate later well heater bottom perforate, set up the condensate discharge pipe at II, increases the condensate discharge mouth; At position mounted valve, be used to regulate the aperture size simultaneously near well heater.
The above-mentioned condensate discharge pipe of setting up is 1～2.
The principle of work of the spissated condensate discharge device of multiple-effect is: by the condensate discharge valve opening of flexible control II effect with post-heater, condensate discharge is smooth and easy, has avoided I to imitate concentration systems and has built the pressure, and effectively controls I and imitates the slip boiling temperature.
The spissated condensate discharge device of multiple-effect of the present utility model, investment is few, has solved during the slurry concentrated process monoammonium phosphate is produced II and has imitated enriching slurry is imitated problem from the punishment in advance difficulty to I.Make the operation that production can continous-stable, improved reliability of system operation, increased turndown ratio, reduced operation easier, effectively improved device capbility.Be applicable to heterogeneous isolating multiple-effect concentration and evaporation device.
Description of drawings
Fig. 1 is the structural representation of the spissated condensate discharge device of multiple-effect of the present utility model.1 is reactor among the figure, and 2 is recycle pump, and 3 are I effect evaporator room, and 4 is that I is imitated well heater, 5 is II effect evaporator room, and 6 is that II is imitated well heater, and 7 is the condensate discharge pipe of setting up, and 8 is original condensate discharge pipe, 9 is the steam inlet pipe, and 10 is secondary steam pipe, and 11 is valve, and 12 is sour pump.
Embodiment
Embodiment: urn good fortune phosphate fertilizer plant of Wengfu Group Co., Ltd. powdery monoammonium phosphate production equipment comprises that reactor 1, recycle pump 2, I imitate evaporator room 3, I and imitate well heater 4, II and imitate evaporator room 5, II and imitate well heater 6, steam inlet pipe 9 and secondary steam pipe 10, a condensate discharge pipe 8, repeatedly runs into II during production and imitates the phenomenon that I is imitated the punishment in advance difficulty.Run into this problem or reduce load production, or minimumly need 20h to stop to clean, which kind of method all greatly reduces the throughput of device.Use the utility model, imitate well heater 6 bottom perforates, set up condensate discharge pipe 7, increase the condensate discharge mouth at II; Simultaneously at the position mounted valve 11 of imitating well heater 6 near II.It is remarkable to implement the back effect, increases seldom investment, has just thoroughly solved this phenomenon, for annual the increasing of this device goes up the kiloton monoammonium phosphate product, thereby reaches the design production capacity.
Claims (2)
1. the spissated condensate discharge device of multiple-effect is characterized in that imitating well heater (6) bottom at II sets up condensate discharge pipe (7); Simultaneously at position mounted valve (11) near well heater (6).
2. the spissated condensate discharge device of multiple-effect according to claim 1 is characterized in that the described condensate discharge pipe of setting up (7) is 1～2.
