Description
Technical field
The present invention is the recycle device of waste heat and dust in a kind of reclaimed copper refining flue gas.Belong to the method for UTILIZATION OF VESIDUAL HEAT IN and exhaust-gas treatment.
Background technology
Reclaimed copper refining is with blister copper, copper scap for raw material, and prepare the smart copper of copper content >=99.3% through processing refining, then cast molding, makes the process of copper ingot or positive plate.
The operation of regeneration Rotary Anode Furnace in Copper is divided into the four-stage that feeds intake, is oxidized, reduces and casts.Wherein the flue-gas temperature of oxidation stage discharge is at 1200 ~ 1300 DEG C, and flue gas containing a large amount of dust, and carries the metallic particles of semi-molten state; At reduction phase, adopt heavy oil as reducing agent, its utilization rate is lower than 30%, and remaining is 70% with fume emission, and the flue-gas temperature of reduction phase is up to 1400 DEG C.In reclaimed copper refining process, the heat that flue gas is taken away accounts for the over half of metal smelt total energy consumption.Therefore, in reclaimed copper refinery processes, the waste heat carried in the flue gas of discharge is valuable heat resource.Recycled for economize energy significant.Meanwhile, the recycling of the heat energy that the flue gas that reclaimed copper refinery practice discharges carries is the important step that reclaimed copper refining enterprise reduces energy consumption and production costs.
Containing copper metal and various valuable element in a large amount of exhaust gas dusts that reclaimed copper refining produces.In order to improve smelting recovery, and reclaiming valuable element, reducing environmental pollution simultaneously, the recovery of exhaust gas dust has Important Economic benefit and environmental benefit.
In prior art, the recycling of reclaimed copper refining fume afterheat, mostly adopts waste heat boiler, and only recycle high-temperature flue gas waste heat, middle-low temperature heat is not also essentially completely recovered utilization, and the heat exchange efficiency of traditional waste heat boiler is low.Therefore, there is the residual heat resources rate of recovery lower.Part of waste heat is still had to enter air with tail gas.Both wasted energy, again contaminated environment.
In reclaimed copper refining flue gas of the prior art, the recovery method of dust, has dry method to gather dust and wet dust collector.Dry method gather dust reclaim dust use more, there is process control instability, burn out cloth bag recover, or cloth bag blocking fault happen occasionally, cause stop.Have a strong impact on steady production, and energy consumption is higher, dust reclaims not exclusively.Tail gas enters air, causes environmental pollution.
One not only reclaims high-temperature residual heat, and reclaims middle-low temperature heat, and waste heat recovery efficiency is high, and dust reclaims completely, and the recycle device of waste heat and dust in the lower desirable reclaimed copper refining flue gas of cost recovery, is that people expect.
