Described flue type waste heat boiler divides rise and fall two-period form flue, and the flue entrance section adopts straight-through uptake flue formula structure, and the flue inwall is equipped with fin panel casing; The exhaust-heat boiler inlet inner wall overlaying has high-temp corrosion-resisting alloy.
Described top-blown converter outlet is connected with the import of flue type waste heat boiler to be adopted with the gland sealed flexible connection mode, and heat boiler outlet and rear portion flue directly weld.
The boiler-steam dome operating pressure of described waste heat boiler is 1.25Mpa, and stove water saturation temperature is 194 ℃.Stove water saturation temperature is higher than the dew-point temperature of sulfureous in flue gas acid, HCl steam, avoids the steam dewfall of sulfuric acid and HCl on the boiler heat exchange face.
Described low-grade composition brass flue gas during smelting purification, the gas cleaning of waste-heat recovery device, exhaust heat recovering method, comprise the steps: that the high-temperature flue gas of top-blown converter output enters the uptake flue of waste heat boiler, when high-temperature flue gas is flowed through the inboard fin panel casing of boiler flue, heat passes to water-cooling wall from flue gas, the cold water heat absorption evaporation in the water screen tube.The cigarette ash that is adsorbed on water-cooling wall is by the rapping spring action blow converter that returns back to top that drops, oxygen content in the oxygen on-line detector on-line monitoring flue gas of boiler export flue, in case abnormal combustion is arranged, the rich-oxygen nozzle that starts on the water-cooling wall blasts oxygenized air combustion supporting, flue gas enters spray cooling tower by the boiler downward-flow flue, spray cooler is injected at a high speed water smoke is down in 250 ℃ flue-gas temperature, the panel cooler of flowing through subsequently, further with below the cigarette temperature drop to 170 ℃, the dust that flue gas is separated out after cooling drops down onto below ash bag, and remaining dust contained flue gas still reaches 50mg/Nm
3Active carbon injection apparatus before the bagroom on the pipeline sprays into active carbon on time, according to quantity, dioxin particle in the absorption flue gas, the quench air inlet valve of bagroom entrance is looked inlet flue gas temperature and is automatically opened in the too high situation of flue-gas temperature, suck cold air, reduce flue-gas temperature, bagroom tail gas dust-laden＜25mg/Nm out
3, drain into the 60m chimney stack through smoke exhaust fan and enter atmosphere.
Described low-grade composition brass flue gas during smelting purifies, the operation principle of waste-heat recovery device and process: the high-temperature flue gas that top-blown converter produces, be inhaled into waste heat boiler two-period form flue, the circulating water reclamation of boiler film-type water-cooling inwall a large amount of waste heat in the flue gas, producing steam electrolysis production heating uses, and flue-gas temperature in this process from about 1100 ℃ 600 ℃ of dropping to outlet temperature of exhaust-heat boiler inlet temperature, for preventing the wall bubble that forms in the lower boiler tube of the high-temperature flue gas baking floating of growing up, dry combustion method appears in the accompanying tube wall of steam bubble, adopts circulating pump to force cooling.The exhaust-heat boiler inlet section adopts straight-through uptake flue formula structure, high-melting-point substances is separated out and is attached on the water-cooling wall in the flue gas, the rapping spring that is arranged on the water-cooling wall outside forms regular resonance to water-cooling wall, make and separate out cigarette ash and fall back to top-blown converter, reduce the dust content of rear portion flue gas, improve the copper amount of producing.Because the halogen that organic burning can produce in the useless composition brass of flue gas can be combined to high temperature corrosion gas attack inboard wall of furnace body, the exhaust-heat boiler inlet inner wall overlaying has the corrosion-and high-temp-resistant alloy.Oxygen content is to judge the complete effect of burning in the oxygen on-line detector on-line monitoring flue gas of boiler export flue, in case abnormal combustion is arranged, the rich-oxygen nozzle that starts on the water-cooling wall blasts oxygenized air combustion supporting.Enter spray cooler through the spray of water smoke from waste heat boiler flue gas out, make flue gas 250 ℃～600 ℃ interval quenchings, contained that organic intermediate products forms dioxin.Flue-gas temperature even guarantee flue gas flow or temperature fluctuation, always keep dry in the tower, along with heat is evaporated taking away of moisture, can make flue gas be cooled to preference temperature by computer system control.The spray of flue gas process spray cooler enters plate type flue gas cooler and further enters bagroom after the cooling, panel cooler is to take away the cooling device of high-temperature flue gas tube wall heat in the mode of forced convertion, indirectly cooling, by axial flow fan for cooling, with entrance flue gas temperature from approximately 350 ℃ be down to the outlet below 170 ℃.The speed of axial flow fan for cooling can manual adjustments be controlled, temperature according to the control of bagroom entrance is different, its speed of service is also different, when the bagroom inlet temperature raises continuously, and the also corresponding raising of the speed of axial flow fan for cooling and the cooling effectiveness of cooler.In addition, in order to adsorb the dioxin that may form in the flue gas, the active carbon spraying system is set before bagroom, in flue gas, sprays activated carbon powder, so that the dioxin in the absorption flue gas.After cooled dusty gas entered dust-precipitator from air inlet, air-flow just diverted flow entered ash bucket, and air velocity is slack-off simultaneously, because effect of inertia makes the crude particle dust in the gas directly fall into ash bucket, played the effect of gathering dust in advance.Tiny dust is trapped in the outer surface of filter bag, and purified gas enters the clean room on top, filter bag chamber, is pooled to air outlet and discharges.The deashing of filter bag adopts compressed air, each filter bag is carried out automatic ash removing by the time interval that PLC is given.Compressed air is ejected by each eyelet of injection tube, and the dust that bonds on the filter bag is got off clearly, makes cloth bag keep ventilating smooth and easy, continuously operation, bagroom is a kind of efficient dust collection device, as long as filter bag is not damaged, its dust collection rate can be greater than 95%, and flue dust character is little on the dust-collecting efficiency impact.The cigarette ash that spray cooling tower, panel cooler, bagroom are collected is packed grey bag into, send corresponding PROCESS FOR TREATMENT, valuable metal is reclaimed to greatest extent, and the flue gas after bagroom is processed enters atmosphere through smoke exhaust fan, chimney, and final tail gas dust-laden is less than 25mg/Nm
3
The invention has the beneficial effects as follows:
1, reclaimed the waste heat of high-temperature flue gas in the reclaimed copper smelting equipment top-blown converter smelting process, this purification, recovery system technology are advanced, adaptability to raw material is strong, the rate of recovery is high, energy consumption is low.
2, adopt spray cooling tower and active carbon injection apparatus, contained the generation of dioxin gas in the flue gas.
3, utilize the clarifying smoke effect of spray cooling tower, panel cooler and bagroom, make the discharged gas fume dust-laden less than 25mg/Nm
3
4, adopt the boiler low pressure operation, and at the exhaust-heat boiler inlet section inner wall overlaying of corrosion-vulnerable high-temp corrosion-resisting alloy is arranged, stoped the corrosion of flue gas to the stove inwall, prolong waste heat boiler service life.
