Description
Technical field
The present invention is the recycle device of waste heat and dust in a kind of reclaimed copper refining flue gas.The method that belongs to UTILIZATION OF VESIDUAL HEAT IN and exhaust-gas treatment.
Background technology
The reclaimed copper refining is that to take blister copper, useless composition brass be raw material, prepares the smart copper of copper content >=99.3% through the processing refining, and the process of copper ingot or positive plate is made in then cast molding.
Regeneration Rotary Anode Furnace in Copper operation be divided into feed intake, oxidation, reduction and casting four-stage.Wherein the flue-gas temperature of oxidation stage discharge is at 1200～1300 ℃, and flue gas contains 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 ℃.In the 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 practice process, the waste heat carried in the flue gas of discharge is valuable heat resource.By it, recycle for saving the energy significant.The recycling of the heat energy that simultaneously, the flue gas of reclaimed copper refinery practice discharge carries is the important step that reclaimed copper refining enterprise reduces energy consumption and production costs.
Contain copper metal and various valuable element in a large amount of exhaust gas dusts that the reclaimed copper refining produces.In order to improve smelting recovery, and reclaim valuable element, the while environmental contamination reduction, 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 adopt waste heat boiler, only the high-temperature flue gas waste heat recycled, and middle-low temperature heat is not also recycled fully, and the heat exchange efficiency of traditional waste heat boiler is low.Therefore, exist the residual heat resources rate of recovery lower.Still have part of waste heat to enter atmosphere with tail gas.Both wasted energy, again contaminated environment.
In reclaimed copper refining flue gas of the prior art, the recovery method of dust, have dry method to gather dust and wet dust collector.Dry method is gathered dust and is reclaimed dust and use morely, exists process control unstable, burns out the cloth bag recover, or the fault that cloth bag stops up happens occasionally, and causes stopping.Have a strong impact on steady production, and energy consumption is higher, dust reclaims not exclusively.Tail gas enters atmosphere, causes environmental pollution.
A kind of high-temperature residual heat that not only reclaims, and reclaim middle-low temperature heat, waste heat recovery efficiency is high, and dust reclaims fully, 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.
