The accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment, wherein: 1 urine groove; 2 evaporation heaters; 3 gas-liquid separators; 4 evaporative condensers; 5 two-section evaporating heaters; 6U type pipe; 7 one sections evaporation ejectors; 8 heat exchange condensers; 9 dual circulation separators; 10 dual circulation the first condensers; 11 dual circulation injectors; 12 dual circulation the second condensers; 13 dual circulation the second injectors; 14 final coolers; 15 Melting pumps; 16 granulation towers; 17 scrapers; 18 weighing-appliances.
The specific embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described, embodiment does not form restriction of the present utility model.
Embodiment
As shown in Figure 1, a kind of evaporation prilling device for preparing urea, comprise urine groove 1, urine groove 1 pipeline connects evaporation heater 2, evaporation heater 2 connects gas-liquid separator 3, gas-liquid separator 3 is provided with gas piping, and gas piping passes into evaporative condenser 4, and the liquid line of evaporative condenser 4 connects two-section evaporating heater 5.The liquid line of evaporative condenser 4 enters in the tubulation of two-section evaporating heater 5 through U-shaped pipe.Evaporative condenser 4 connects one section rear connection final cooler 14 of evaporation ejector 7.Two-section evaporating heater 5 connects dual circulation separator 9.Dual circulation separator 9 connects dual circulation the first condenser 10, dual circulation the first condenser 10 connects dual circulation injector 11, dual circulation injector 11 connects dual circulation the second condenser 12, and dual circulation the second condenser 12 connects final cooler 14 by dual circulation the second injector 13.Dual circulation separator 9 connects granulation tower 16, and there are scraper 17 and travelling belt in granulation tower 16 belows.Also comprise weighing-appliance 18.
The course of work that the present embodiment prepares the evaporation prilling device of urea is:
Be 72% left and right from the urine concentration of urine groove 1, by urine, be pumped into evaporation heater 2 bottoms.
Low-pressure steam makes urine be heated to 130.From evaporation heater 2, gas-liquid mixture out rises to gas-liquid separator 3 and carries out gas-liquid separation, and gas enters in evaporative condenser 4, and liquid is in U-shaped pipe enters the tubulation of two-section evaporating heater 5.Evaporative condenser 4 outlet incoagulable gas are evacuated to final cooler 14 condensations, the vacuum of regulating one section evaporation by one section evaporation ejector 7.
Gas, liquid mixture enter dual circulation separator 9.Gas is delivered in dual circulation the first condenser 10 through stepup transformer, uncooled gas is evacuated in dual circulation the second condenser 12 by dual circulation injector 11, wherein uncondensed gas is evacuated to condensation in final cooler 14 by dual circulation the second injector 13 again, after drain into chimney.Enter system by regulating a certain amount of air, can regulate the vacuum of dual circulation.
From the dual circulation separator, concentration out is 99.7% fusing urea, is delivered to the prilling spry at granulation tower 16 tops by Melting pump 15.While stopping granulation, during urine is returned via triple valve; Start can pass into steam condensate clean cycle pipeline after granulation.After the urine ejection entered, the air entered at the bottom of tower is cooling.Fall the urea granules that column bottom temperature is about 70, scraped into blanking groove by scraper 17, after the granulation tower belt is sent into equipment 18 and is weighed directly to the finished product packing building.
