Description
Technical field
The utility model relates to metallurgical field of smelting, the furnace cupola of specifically a kind of waste heat recovery.
Background technology
Furnace cupola is the visual plant of melting iron in Foundry Production, is poured into and unpacks after cooling in sand mold and obtain foundry goods after casting pig being fused into molten iron.Furnace cupola is a kind of vertical cylindrical shape smelting furnace, and furnace roof is provided with heat exchanger, is mainly used in iron casting production, also in order to coordinate pneumatic steelmaking, because of furnace roof opening upwards, therefore claims furnace cupola.The combustion-supporting air port of existing furnace cupola is equipped with multiple, and is distributed in shaft surrounding, therefore causes wind direction heterogeneity in stove, cause the situation that gas flowing is not smooth, and through the combustion air of preheating, a point multiple airduct enters in stove and thermal loss can be caused excessive, is unfavorable for fusing.And furnace cupola send the flue gas of discharge to have very high temperature, general direct discharge or discharge after treatment, recycling relatively less, causes the huge waste of energy.
Utility model content
The purpose of this utility model is the furnace cupola providing a kind of waste heat recovery, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the utility model provides following technical scheme:
A kind of furnace cupola of waste heat recovery, comprise body of heater, gas outlet and stove seat, described body of heater is fixedly arranged on stove seat, heat-insulation layer is provided with in described body of heater, heat-exchange tube is provided with in described heat-insulation layer, described inboard wall of furnace body is provided with flame retardant coating, described stove seat lower end is provided with discharge nozzle, described discharge nozzle is provided with detector, described sidewall of the furnace body lower end is provided with cooler, described cooler lower end is connected with cooling water inlet pipe by intake pump, described cooler upper end connects heat-exchange tube, described cooler is also connected with the air inlet pipe be communicated with furnace interior, described air inlet pipe is provided with magnetic valve, controller is connected with between described magnetic valve and detector, described gas outlet is fixed on body of heater top, described gas outlet top is installed with chimney, multiple water jacket is provided with in described gas outlet, the multiple connecting water pipes perpendicular to water jacket are provided with in the middle of described water jacket, described water jacket upper end is connected with outlet pipe, described water jacket lower end is connected with water inlet pipe.
As further program of the utility model: described water jacket is hollow ellipse shape, and water jacket is communicated with connecting water pipe.
As the utility model further scheme: described water jacket is provided with 4 ~ 6 layers.
Compared with prior art, the beneficial effects of the utility model are: the utility model device by the detector arranged detect material in discharging opening discharging flow and by signal transmission to controller, thus Controlling solenoid valve controls air inflow, the reaction controlling material in body of heater is carried out smoothly, thus ensures the quality of product; Air inlet pipe is only provided with one simultaneously, thus ensures that the air in air inlet pipe enters in body of heater uniformly, reduces the loss of stove intimate heat; The preheating that the hollow ellipse water jacket arranged and heat-exchange tube Cupola top are discharged absorbs, and the water jacket of ellipse adds the area of exchange heat, therefore increase the uptake to waste heat in gas outlet, improve the utilization rate of waste heat of cupola furnace and the utilization rate of the energy.
