Description
Technical field
A kind of ammonia still vapor-recovery system is the utility model is related to, belongs to coal chemical industry equipment technical field.
Background technology
In coal chemical industry synthesis technique, it is necessary to using liquefied ammonia as cooling agent, liquefied ammonia is transformed into after amount of heat is absorbed
Gas ammonia.In order to realize that recycling for refrigerant ammonia, existing process obtain concentrated ammonia liquor after absorbing gas ammonia using water, ammonia still is utilized
Rectifying is carried out to concentrated ammonia liquor, obtained gas ammonia enters back into cooler and is condensed into liquefied ammonia.In the system using the indirect ammonia still process of steam,
The Low Temperature Steam come out from ammonia still is entering steam condensate groove after condensation, is provided by desalination and deoxygenation rear line
Deaerated water.The problem of above-mentioned flow is present be, the vapor (steam) temperature come out from ammonia still is higher, after condensation, into steam
The condensate liquid for condensing liquid bath is still steam water interface, and when to desalted water oxygen-eliminating device feed flow, liquid-feeding pump is unable to trouble-free operation, and pole holds
It is fragile；In addition, the steam come out from ammonia still still has higher temperature, this partial heat is completely wasted.
The content of the invention
The purpose of this utility model is to provide a kind of ammonia still vapor-recovery system, including ammonia still and steam condensate
Groove, the ammonia still are steam indirect heating type, and ammonia still is provided with steam inlet and steam (vapor) outlet, the steam (vapor) outlet and steam
Liquid bath connection is condensed, afterheat generating system, the cogeneration system are connected between the steam (vapor) outlet and steam condensate groove
Unite as low-temperature generating system.
Further, the low-temperature generating system is organic media cycle generating system.
Further, the organic media cycle generating system includes medium heat exchanger, and the medium heat exchanger leads to
Cross circulating line to be connected with steam turbine and devaporizer, the steam turbine is used to drive generator, and the devaporizer leads to
Medium circulation pump is crossed to be connected with media heat exchanger.
Further, the steam condensate groove is connected with deoxygenation water supply system.
Further, the deoxygenation water supply system includes desalted water oxygen-eliminating device, the desalted water oxygen-eliminating device and deaerated water
User connects；Liquid-feeding pump is provided between the desalted water oxygen-eliminating device and steam condensate groove.
Further, the deaerated water user includes the useless pot of gasification, the useless pot of conversion and the useless pot of synthesis.
Beneficial point of the present utility model is that the ammonia still vapor-recovery system in this programme can be carried out to steam waste heat
Make full use of, save the energy；Steam after heat recovery simultaneously, it is ensured that its total condensation, avoid cold in steam
Steam water interface in condensate tank be present, damaged so as to eliminate liquid-feeding pump in follow-up deoxygenation water supply system, Wu Fazheng
The problem of normal feed flow.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
A kind of ammonia still vapor-recovery system as shown in Figure 1, including ammonia still 1 and steam condensate groove 7, the ammonia still process
Tower 1 is steam indirect heating type, and ammonia still 1 is provided with steam inlet and steam (vapor) outlet, the steam (vapor) outlet and steam condensate groove 7
Connection, is connected with afterheat generating system, the afterheat generating system is low temperature between the steam (vapor) outlet and steam condensate groove 7
Electricity generation system.The low-temperature generating system is organic media cycle generating system.The organic media cycle generating system includes
Medium heat exchanger 2, the medium heat exchanger 2 are connected by circulating line with steam turbine 3 and devaporizer 5, the vapour
Turbine 3 is used to drive generator 4, and the devaporizer 5 is connected by medium circulation pump 6 with media heat exchanger 2.The steam
Condensation liquid bath 7 is connected with deoxygenation water supply system.The deoxygenation water supply system includes desalted water oxygen-eliminating device 9, the desalted water
Oxygen-eliminating device 9 is connected with deaerated water user；Liquid-feeding pump 8 is provided between the desalted water oxygen-eliminating device 9 and steam condensate groove 7.It is described
Deaerated water user includes the useless pot 11 of gasification, the useless pot 12 of conversion and the useless pot 13 of synthesis.
The operation principle of the present embodiment is about 140 DEG C of the vapor (steam) temperature come out from ammonia still, is steam water interface, is entered
After medium heat exchanger, steam is exchanged heat with organic media, organic media gasification expansion, pushing turbine acting, so as to drive
Dynamic generator is generated electricity, and the organic media after gasification uses through devaporizer condensation Posterior circle；Vapor (steam) temperature after heat exchange
85 DEG C or so are reduced to, goes completely into condensate liquid, into steam condensate groove, is provided through desalted water oxygen-eliminating device deoxygenation rear line
Deaerated water.
Ammonia still vapor-recovery system in this programme can make full use of to steam waste heat, save the energy；Simultaneously
Steam after heat recovery, it is ensured that its total condensation, avoid and steam water interface be present in steam condensate groove
Situation, damaged so as to eliminate in follow-up deoxygenation water supply system liquid-feeding pump, can not normal feed flow the problem of.
