Abstract
The utility model discloses an ammonia waste water heating furnace which belongs to the coking equipment, in particular to a supporting device of ammonia-distill tower. The ammonia waste water heating furnace comprises a heating furnace body, furnace legs, a combustor and a chimney, and is characterized in that a heating furnace tube is arranged inside the heating furnace body; the bottom part of the furnace body is provided with the combustor; the top part of the heating furnace body is provided with a waste water pre-heater; the upper part of the pre-heater is provided with a smoke gas surplus heat recycler; a pre-heating water outlet of the waste water pre-heater is connected with a heating water inlet, and the hot air outlet of the surplus heat recycler is connected with an air outlet of the combustor on the bottom part of the furnace body. The utility model provides an ammonia waste water heating device; coke-oven gas is utilized to heat the ammonia waste water to an over-heated status, and then the ammonia waste water is sent into the tower, so that the over-heated water is changed to be steam at the moment entering the tower so as to steam the ammonia, and the condensed water is recycled to the heating furnace to heat. With the ammonia waste water heating furnace, external steam can be saved, and partial ammonia waste water is utilized, so that the waste water discharging quantity can be reduced, thereby saving energy and protecting the environment.
Description
Technical field
The utility model belongs to coker, particularly the corollary equipment of ammonia still.
Background technology
Can produce a large amount of ammonia-containing waters in the coking industry production process, waste water does not allow to efflux because of containing the ammonia event, and ammonia-containing water is serious to metal erosion, so must discharge after the ammonia extraction again.Traditional method is that waste water is sent in the ammonia still, distills with a large amount of steam, and ammonia is extracted.This method is used steam expense height, and pressure transient, and steam condensate (SC) mixes wastewater flow rate is strengthened simultaneously, so this technology falls behind, efficient is low, energy consumption is high, pollution is big.
The utility model content
Use steam distillation to carry ammonia in order to overcome existing ammonia still, the deficiency of energy consumption height, increase wastewater flow rate, the purpose of this utility model provides a kind of distilled ammonia wastewater heating furnace, and this distilled ammonia wastewater heating furnace is thermal efficiency height not only, and can not increase the quantity of ammonia-containing water.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of distilled ammonia wastewater heating furnace, comprise heating furnace body, stove leg, burner, chimney, it is characterized in that: furnace tubing is housed in the heating furnace body, bottom of furnace body is equipped with burner, the waste water preheater is equipped with at the heating furnace body top, preheater top is the flue gas waste heat recovery device, and the preheating water outlet of waste water preheater connects and adds the hot water inlet, and the waste-heat recoverer hot-blast outlet connects the air intlet of bottom of furnace body burner.
Described furnace tubing be spiral coil its add hot water outlet and be connected with ammonia still.
The preheating water inlet that described waste water preheater is finned coiled pipe preheater is connecting the ammonia still wastewater outlet.
Described flue gas waste heat recovery device is the heat pipe-type waste-heat recovery device.
The utility model provides a kind of ammonia still waste water firing equipment, utilizes coke-stove gas that distilled ammonia wastewater is heated to superheat state, carries in tower then, and superheated water is gone into tower and promptly become water vapour and carry out ammonia still process, and condensed water returns heating furnace circulation heating again.Using this equipment can save external steam, utilized the part distilled ammonia wastewater can reduce wastewater discharge simultaneously, is a kind of new equipment of energy-saving and environmental protection.
Description of drawings
Accompanying drawing 1 is a structural representation of the present utility model,
Among the figure, 1. cold wind import, 2. waste-heat recoverer, 3. waste water preheater, 4. the preheating water inlet 5. adds hot water outlet, 6. heating furnace body, 7. furnace tubing, 8. burner, 9. the stove leg 10. adds the hot water inlet, the outlet of 11. preheating water, 12. hot-blast outlets, 13. chimneys.
The specific embodiment
The specific embodiment of the present utility model is, as shown in the figure:
Waste water from ammonia still enters waste water preheater 3 by water pump through preheating water inlet 4, come out to enter heating furnace 6 by outlet 11 after the preheating, be heated to more than 120 degree, flow out by outlet 5 by adding hot water inlet 10, reached superheat state, can enter ammonia still according to the amount of technological requirement; Tank in the middle of condensed water after the heat release falls at the bottom of the tower is drawn back into stove by water pump then and is circulated.The waste water preheater has adopted advanced finned tube to carry out heat exchange, to improve the thermal efficiency.Through heat pipe-type waste-heat recoverer 2, the waste heat after the recovery can be heated to the 100-150 degree to cold air and send into burner 8 again before the stove flue gas was overflowed.But energy savings but also can improve efficiency of combustion greatly not only.
Claims (4)
1. distilled ammonia wastewater heating furnace, comprise heating furnace body, stove leg, burner, chimney, it is characterized in that: furnace tubing is housed in the heating furnace body, bottom of furnace body is equipped with burner, the waste water preheater is equipped with at the heating furnace body top, preheater top is the flue gas waste heat recovery device, and the preheating water outlet of waste water preheater connects and adds the hot water inlet, and the waste-heat recoverer hot-blast outlet connects the air intlet of bottom of furnace body burner.
