Abstract
The utility model discloses an air and gas preheater which comprises a furnace body, wherein a dummy plate is arranged in the middle of the furnace body, and enables the furnace body to be divided into an upper heat transfer chamber and a lower heat transfer chamber, multirow and multicolumn finned tubes are transversely arranged in the upper heat transfer chamber and the lower heat transfer chamber, an air and gas inlet is arranged on one side of the lower heat transfer chamber, an air and gas outlet is arranged on the same side with the lower heat transfer chamber in the upper heat transfer chamber, an air and gas passageway is arranged on one side of the furnace body, and the air and gas inlet, the finned tubes in the lower heat transfer chamber, the air and gas passageway, the finned tubes in the upper heat transfer chamber and the air and gas outlet form a sealed air and gas circulating passageway. A smoke gas inlet is arranged on the upper portion of the furnace body, and a smoke gas outlet is arranged on the lower portion of the furnace body. According to the air and gas preheater, smoke gas of a lime kiln is utilized to preheat air and gas, so that burning temperature of the air and the gas can be improved, and normal operation of manufacturing technique is achieved. Meanwhile, the smoke gas of lime window is recycled, so that thermal pollution to environment is reduced.
Description
Technical field
The utility model relates to a kind of heat-exchange device, relates in particular to the air ﹠ gas heater that a kind of limekiln is used or other industry is used.
Background technology
Along with the continuous increase of domestic steel production capacity, also increasing to the demand of lime (CaO).Each iron and steel enterprise utilizes blast furnace air, the coal gas of producing from height furnace, is transported to the limekiln and acts as a fuel and carry out lime calcining and therefrom obtain calcium constituent and meet the needs of production.Blast furnace gas is the byproduct of blast furnace ironmaking, the important gas fuel of integrated iron and steel works inside, but because the theoretical temperature combustion of blast furnace gas is low than other air, coal gas, ignition temperature only has 1400～1500 ℃, in most cases the blast furnace gas preheating must be improved its ignition temperature, could satisfy the normal operation of production technology, and the flue-gas temperature after the burning of limekiln is very high, contain a large amount of heat, directly be discharged into the waste that can cause undoubtedly the energy in the atmosphere, cause simultaneously environmental thermal pollution.
Summary of the invention
The utility model provides a kind of air ﹠ gas heater, utilize the flue gas in limekiln to come preheated air, coal gas, in the hope of improving the ignition temperature of air, coal gas, satisfy the normal operation of production technology, simultaneously the flue gas of lime window re-used environmental contamination reduction.
To achieve these goals, the technical solution of the utility model is: a kind of air, gas preheater, comprise body of heater, described body of heater middle part arranges dividing plate makes body of heater be divided into upper thermal exchanging chamber and lower thermal exchanging chamber, the finned tube of arranging multiple row along horizontally set is set in upper thermal exchanging chamber and the lower thermal exchanging chamber more, lower thermal exchanging chamber's one side arranges air, gas inlet, the homonymy of upper thermal exchanging chamber arranges air, gas exit, one side of body of heater arranges air, gas passage, air, gas inlet, finned tube in the lower thermal exchanging chamber, air, gas passage, finned tube in the upper thermal exchanging chamber, air, gas exit forms the air of a sealing, the coal gas circulation canal; On the described body of heater gas approach is set, the lower exhanst gas outlet that arranges.
Further, described finned tube is the nickel-based brazing bidirectional finned tube imbedded.
Further, bottom, described lower thermal exchanging chamber lower end arranges drain outlet.
Further, described air gas import, air gas outlet, gas approach, smoke outlet arrange thermo detector.
Further, described thermometric is counted thermocouple thermometer.
Air ﹠ gas heater of the present utility model, utilize the flue gas in limekiln to come preheated air, coal gas, in the hope of improving the ignition temperature of air, coal gas, satisfy the normal operation of production technology, simultaneously the flue gas of lime window re-used, reduce environmental thermal pollution.
