The key point is that: the system comprises a high-temperature radiation type waste heat boiler, a shell-and-tube heat exchanger and a low-temperature convection type waste heat boiler which are sequentially connected from a high-temperature region to a low-temperature region. The system adopts a flue type three-level combined waste heat recovery system, effectively reduces the smoke exhaust temperature of the smoke, improves the recovery efficiency of the waste heat, achieves obvious effects of saving energy and reducing emission, can be widely applied to waste heat recovery treatment on the high-temperature smoke generated in various metallurgical production processes, and has extremely high popularization and application value.
Description
Technical field
The utility model relates to a kind of high-temperature flue gas waste heat reclaiming process device.
Background technology
Metallurgy is an extracting metals from metallic ore, purification and synthetic metal, and with the process of made utility.No matter being iron and steel industry or nonferrous metallurgy, all is the operation to various minerals, and its smelting and manufacturing a product is at high temperature carried out mostly, inevitably will produce a large amount of high-temperature flue gas (900 ℃-1100 ℃) in the production process; Past, this high-temperature flue gas was directly arranged to atmosphere, had caused the huge waste of the energy; This nearly 1000 ℃ high-temperature flue gas treatment process has caused extensive concern at present.Be energy savings; Reclaim fume afterheat; Usually make the outlet high-temperature flue gas of smelting furnace pass through waste heat boiler and convection recuperator successively; Mostly the temperature of discharging gas be more than 350 ℃, this part gas directly row to atmosphere or mix cold wind again and reduce to back below 200 ℃ and get into after the smoke duster dedusting through smoke stack emission.The waste heat boiler of this flue gas process flow process and convection recuperator have reclaimed a large amount of smoke discharging residual heats; Can flue-gas temperature be reduced to ~ 300 ℃; But exhaust gas temperature is still higher, mixes the cold wind cooling and has equally also caused the waste of the energy, and can increase the power that draws (sending) blower fan.
The utility model content
The purpose of the utility model provides a kind of metallurgy high temperature flue gas waste heat recovery system that can fully reclaim the waste heat that high-temperature flue gas carries.
To achieve these goals; Adopt following technical scheme; A kind of metallurgy high temperature flue gas waste heat recovery system is characterized in that: hyperthermia radiation formula waste heat boiler, shell-and-tube heat exchanger and the low temperature convection type waste heat boiler of said system for connecting successively to low-temperature space from the high-temperature region.
The utility model adopts three grades of combinations of chimney flue type residual neat recovering system to effectively reduce the flue gas exhaust gas temperature; Improved waste heat recovery efficient; Effects of energy saving and emission reduction is remarkable; On the waste heat recovery processing of the high-temperature flue gas that can be widely used in producing in the various metallurgical production processes, has high application value.
Figure of description
Fig. 1 is the structural representation of the utility model.
Among the figure, part 1 is a hyperthermia radiation formula waste heat boiler, and part 2 is a shell-and-tube heat exchanger, and part 3 is a low temperature convection type waste heat boiler.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is done and to be further described.
As shown in Figure 1; In the waste heat recovery process; At first in high-temperature flue gas section (900 ℃ ~ 1200 ℃) a cover hyperthermia radiation formula waste heat boiler 1 is set, this waste heat boiler mainly leans on the hyperthermia radiation heat generation steam that absorbs flue gas, reduces flue-gas temperature to 600 ℃ ~ 800 ℃ simultaneously; Again through shell-and-tube heat exchanger 2, utilize fume afterheat to come preheated-combustion-supporting sky, coal gas through the flue gas after the cooling of hyperthermia radiation formula waste heat boiler, sky, gas temperature are preheated to 400 ℃ ~ 500 ℃, flue-gas temperature is reduced to 300 ℃ ~ 400 ℃ simultaneously; Send into low temperature convection type waste heat boiler 3 at last through the flue gas of shell-and-tube heat exchanger, fume afterheat is reclaimed once more, reduce flue-gas temperature (< 190 ℃) to greatest extent.
Wherein hyperthermia radiation formula waste heat boiler and low temperature convection type waste heat boiler can adopt common flue type residual heat boiler; The flue type residual heat boiler is to utilize working medium in the phase transition process under the certain pressure, to absorb a large amount of this characteristics of the latent heat of vaporization; Heat-transfer surface is set in flue reclaims fume afterheat generation steam, reduce the exhaust gas temperature of flue outlet simultaneously.
Shell-and-tube heat exchanger 2 can adopt that drag losses is little, the thermal efficiency is high, the tubulose preheater; The medium that is heated in the heat exchanger is coal gas or air; Coal gas after the heating or air participate in producing again, have improved the hot working efficiency of art production process, have reduced flue-gas temperature simultaneously.
The flue-gas temperature of handling through this residual neat recovering system can directly satisfy follow-up smoke eliminator and discharge to the requirement of cigarette temperature fluctuation or to sky less than 190 ℃; And the steam that waste heat boiler produces is the power working medium of high accumulation of energy, can be used for generating, heating etc., has realized making full use of of fume afterheat, has avoided environmental pollution.
