Abstract
A device for utilizing thermal energy of condensed water of air heaters of a soda recovery furnace is characterized in that after passing through a heating steam mother tube, heating steam is delivered to a steam inlet of a first air heater through a steam branch tube and a check valve; after the heating steam is subjected to heat exchanging via the first air heater, condensed water is drained, is gathered to a first condensed water mother tube via a first condensed water branch tube and a first gate valve, and then enters a flash tank via a second gate valve; after secondary steam generated by the flash tank passes through the steam mother tube, the secondary steam is delivered to a steam inlet of a second air heater through a secondary steam branch tube and a third gate valve; after the secondary steam is subjected to heat exchanging via the second air heater, condensed water is drained, and is gathered to a second condensed water mother tube via a second condensed water branch tube and a fourth gate valve, and the condensed water and the condensed water drained from the flash tank are delivered to a condensed water tank together via a condensed water tube and a fifth gate valve.
Description
Technical field
The utility model belongs to enterprises in pulp and paper industry alkali recovery furnace boiler circuit, is a kind of alkali recovery furnace wind heater condensate water heat-energy utilizing device.
Background technology
Enterprises in pulp and paper industry alkali recovery furnace wind heater heating steam pipe adopts piping-main scheme at present, by steam main, delivers to respectively each wind heater air inlet; Condensate water after the heat exchange of wind heater is pooled to condenses after jellyfish pipe, by drain valve, enters condensate tank.Condensate water pressure, the temperature of due to drain valve, discharging are all higher, enter a large amount of indirect steams that step-down flash distillation produces after condensate tank sky is discharged, and both waste energy, again contaminated environment.
Utility model content
The utility model is intended to develop a kind of alkali recovery furnace wind heater condensate water heat-energy utilizing device, and the heat energy of wind heater being discharged to condensate water makes full use of, and reaches the effect of energy-saving and emission-reduction.
The technical scheme of utility model: alkali recovery furnace wind heater condensate water heat-energy utilizing device, is characterized in that: heating steam, after the female pipe of heating steam, then is delivered to the air intake of wind heater one by steam branch pipe and stop valve; The condensate water of discharging after one heat exchange of wind heater, is pooled to through condensate water arm one and gate valve one the jellyfish Guan Yihou that condenses, then enters flash tank through gate valve two; The indirect steam that flash tank produces, after steam main, then is delivered to the air intake of wind heater two by indirect steam arm and gate valve three; The condensate water of discharging after two heat exchange of wind heater, is pooled to through condensate water arm two and gate valve four the jellyfish pipe two that condenses, and the condensate water of discharging with flash tank is delivered to condensate tank through gate valve five together with condensate pipe.
Advantage of the present utility model: a large amount of indirect steams of current alkali recovery furnace wind heater condensate water discharge are reclaimed, the hot vapour source that adds as next stage wind heater, make full use of its heat and further heat alkali recovery furnace air intake, improve EAT, reduce steam consumption quantity, turn waste into wealth, reduce thermal pollution, energy-saving and emission-reduction, have obtained good economic benefit and environmental benefit.
Accompanying drawing explanation
Accompanying drawing is system diagram of the present utility model.In figure: the female pipe of 1-heating steam, 2-steam branch pipe, 3-stop valve, 4-wind heater one, 5-condensate water arm one, 6-gate valve one, the 7-jellyfish pipe one that condenses, 8-gate valve two, 9-flash tank, the female pipe of 10-indirect steam, 11-indirect steam arm, 12-gate valve three, 13-wind heater two, 14-condensate water arm two, 15-gate valve four, the 16-jellyfish pipe two that condenses, 17-condensate pipe, 18-gate valve five, 19-condensate tank.
The specific embodiment
Embodiment below in conjunction with accompanying drawing further illustrates content of the present utility model.
Alkali recovery furnace wind heater condensate water heat-energy utilizing device.System is set to:
A. heating steam is after the female pipe 1 of heating steam, then delivers to wind heater one 4 air intakes by steam branch pipe 2 and stop valve 3.
The condensate water of b. discharging after one 4 heat exchange of wind heater, is pooled to and condenses after jellyfish pipe 1 through condensate water arm 1 and gate valve 1, then enter flash tank 9 through gate valve 28.
C. the indirect steam that flash tank 9 produces, after the female pipe 10 of indirect steam, more respectively by indirect steam arm 11, through gate valve 3 12, is delivered to wind heater 2 13 air intakes.
The condensate water of d. discharging after 2 13 heat exchange of wind heater is pooled to through condensate water arm 2 14 and gate valve 4 15 the jellyfish pipe 2 16 that condenses, and the condensate water of discharging with flash tank 9 is passed through together with condensate pipe 17, through gate valve 5 18, delivers to condensate tank 19.
