The utlity model has simple in structure, processing ease, can produce urea again can the production high analysis urea-based compound fertilizer, and invest little and be not subjected to the advantage of seasonal effects limit.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
As shown in Figure 1, the utility model comprises that synthetic tower 1 steams urea soln conduit entrance 16, that well heater 5, steams separator 6 upper ends with middle pressure decomposition and separation system 2, low pressure decomposition and separation system 3, flash separation upgrading system 4, successively and steams that separator 6, two steams separating and concentrating systems 7, Melting pump 8 links to each other with prilling tower 9, feed proportioning system successively with comprehensive belt 13, dense phase gases delivery system 14, composite fertilizer's batching opening for feed 17 that valve 15 and steams separator 6 upper ends links to each other; Described one position of steaming composite fertilizer's batching opening for feed 17 of separator 6 upper ends is lower than the position of the urea soln conduit entrance 16 of a steaming separator 6 upper ends; Described feed proportioning system is: opening for feed 10 links to each other with feed belt 11; Described feed proportioning system is at least two covers.Be provided with weighing balance 12 below the described feed belt 11.
As shown in Figure 1, when using the utility model to produce urea, the urea soln that comes out by synthetic tower 1 through in press decomposition and separation system 2, low pressure decomposition and separation system 3, flash separation upgrading system 4, to steam urea soln conduit entrance 16, that well heater 5, steams separator 6 upper ends to steam separator 6, two and steam separating and concentrating systems 7, deliver on the prilling tower 9 air prilling by Melting pump 8 pressurizations; When using the utility model production high analysis urea-based compound fertilizer, equipment during above-mentioned production urea is all opened, feed proportioning system comprises opening for feed 10, feed belt 11 and weighing balance 12, because required multiple composite fertilizer material, so feed proportioning system is at least two, the corresponding separately cover feed proportioning system of each composite fertilizer material is so that accurately measure and in time adjust material rate.Composite fertilizer material process opening for feed 10 enters the feed belt 11 of feed proportioning system, simultaneously by the actual amount that enters comprehensive belt 13 of weighing balance 12 controls, so that control various material rates.Various composite fertilizer materials on the comprehensive belt 13 enter dense phase gases delivery system 14 together, after the 14 sealing pressurizations of dense phase gases delivery system, send into a upper end of steaming separator 6 through valve 15 and the composite fertilizer's batching opening for feed 17 opened, composite fertilizer's batching opening for feed 17 highly is lower than the urea soln conduit entrance 16 of a steaming separator 6 upper ends, to guarantee that a urea soln that steams well heater 5 is sprayed onto on the composite fertilizer material, make mixing of materials, when being heated evenly, prevent that composite fertilizer material from too much producing dust.In the one steaming separator 6 certain liquid level is arranged, liquid level is lower than composite fertilizer's batching opening for feed 17.Composite fertilizer material enters one and steams the high temperature urea soln is mixed and be subjected in separator 6 backs with urea soln heat transfer, temperature raises and forms molten state composite fertilizer slip, these slips enter two and steam separating and concentrating systems 7 and further heat and isolate wherein moisture, enter Melting pump 8 pressurizations then and deliver on the prilling tower 9 air prilling.In order to guarantee can be in happy and harmonious state after each mixing of materials in the steaming separator 6, the mass ratio of high temperature urea soln often will be more than 40%, and the product of production is a high-nitrogen compound fertilizer.When not production composite fertilizer, valve-off 15 and feed proportioning system, comprehensive belt 13 and dense phase gases delivery system 14 get final product.
