Abstract
The utility model relates to a condensation system of an ammonia dephlegmator, which comprises a dephlegmator; the upper section of the dephlegmator is provided with a cooling water inlet I (2) and a cooling water outlet I (6); the lower section of the dephlegmator is provided with a cooling water inlet II (4) and a cooling water outlet II (5); and the cooling water outlet I (6) is connected with the cooling water inlet II (4) by a pipeline. The condensation system of the ammonia dephlegmator greatly improves the cooling effect of ammonia and ensures the pressure of the top of an ammonia distillation column to be stable. The equipment investment is reduced, and the production cost is lowered. The water in a saturator at an ammonium sulphate working section is guaranteed to be balanced, the operation is stabilized, and the recovery rate of the ammonium sulphate is guaranteed.
Description
Technical field
The utility model relates to the cooling apparatus that a kind of coke-oven plant ammonia still process workshop section is used for the ammonia condensation, is specifically related to a kind of condenser system of ammonia reduction appts..
Background technology
No matter adopt which kind of flow process between coke-oven plant's recovery vehicle, all need steam ammonia come with ammonia still, need after the ammonia reduction appts. is with ammonia condensation cooling, can send into next workshop section at the ammonia still process cat head.The condenser system of ammonia reduction appts. of the prior art is as shown in Figure 1, and cold water water is divided into two-way behind water pump 3, and entrance of cooling water I 2 entering reduction appts.s 1 epimere of leading up to carries out heat exchange after cooling water outlet I 6 is discharged; Heat exchange is carried out after cooling water outlet II 5 is discharged through entrance of cooling water II 4 entering reduction appts.s 1 hypomere in another road.Because the shared water pump of two-way condenser system, cooling water flow is inhomogeneous, thereby causes reduction appts. interior ammonia cooling performance in ammonia still top poor, and tower top pressure is unstable.Ammonia outlet is advanced to satisfy and is closed the actuator temperature shakiness, causes the interior mother liquor temperature of sulphur ammonium saturex higher, causes moisture unbalance.
The utility model content
The purpose of the utility model is to solve the above-mentioned technical problem that exists in the prior art, and a kind of condenser system of ammonia reduction appts. is provided.
For realizing above-mentioned purpose, the technical scheme that the utility model adopts is following:
The condenser system of ammonia reduction appts. of the present invention; Comprise reduction appts.; The reduction appts. epimere is provided with entrance of cooling water I and cooling water outlet I, and the reduction appts. hypomere is provided with entrance of cooling water II and cooling water outlet II, and the cooling water outlet I is connected with the entrance of cooling water II through pipeline.
Because the utility model divides the two-way water coolant with an original cooling-water pump; Cool off two sections ammonia in the reduction appts. simultaneously; Change a water pump into and supply one road water coolant, behind the ammonia that cooling reduction appts. epimere temperature is lower earlier, cool off the higher ammonia of reduction appts. hypomere again.Make the two-way water coolant merge into one road water coolant.
Improve the cooling performance of ammonia greatly, stablized the ammonia still top pressure.Reduce investment of devices, reduced production cost.Guarantee the water balance in the ammonium sulfate workshop section saturex, stablized operation, guaranteed the recovery of sulphur ammonium.
Description of drawings
Fig. 1 is the condenser system structural representation of ammonia reduction appts. in the prior art.
Fig. 2 is the condenser system structural representation of ammonia reduction appts. in the utility model.
Embodiment
The condenser system of the utility model ammonia reduction appts.; Comprise reduction appts.; The reduction appts. epimere is provided with entrance of cooling water I 2 and cooling water outlet I 6, and the reduction appts. hypomere is provided with entrance of cooling water II 4 and cooling water outlet II 5, and cooling water outlet I 6 is connected with entrance of cooling water II 4 through pipeline.
In the working process, water coolant carries out heat exchange after cooling water outlet I 6 is discharged through water pump 3 through entrance of cooling water I 2 entering reduction appts.s 1 epimere, carries out heat exchange after cooling water outlet II 5 is discharged through entrance of cooling water II 4 entering reduction appts.s 1 hypomere then.
Claims (1)
1. the condenser system of an ammonia reduction appts.; Comprise reduction appts.; The reduction appts. epimere is provided with entrance of cooling water I (2) and cooling water outlet I (6); The reduction appts. hypomere is provided with entrance of cooling water II (4) and cooling water outlet II (5), it is characterized in that: cooling water outlet I (6) is connected with entrance of cooling water II (4) through pipeline.
