Technical field
The present invention relates to the copper metallurgy furnace flue gas exhaust heat Application ways that a kind of deduster carries exhaust tube, specifically can be most
Limits thermal energy in recovered flue gas be converted into high-grade electric energy, and dust collection capacity can be improved, belong to copper smelter UTILIZATION OF VESIDUAL HEAT IN
And dedusting technology field.
Background technology
Metallurgy industry consumes mass energy every year, and the high-temperature flue gas and equipment cooling generated in smelting process has been taken away largely
Energy.Since copper smelter flue-gas temperature is very high, into pipeline temperature generally at 750 DEG C or so, dust concentration reaches 15g/Nm3,
Ash less than 5um accounts for more than the 65% of dust total amount, and Dust Capacity is big, and viscous and thin.And flue-gas temperature big ups and downs, dust-laden
Amount is big, and common water row tube waste heat boiler is difficult the waste heat recovery for applying to copper metallurgy kiln gas.At present, heat-pipe heat exchanger into
Work(is applied in the flue gas waste heat recovery of copper smelter, but (cost is high, not freeze proof, non-refractory, makes due to the inherent shortcoming of heat pipe
It is short with the time limit) so that heat pipe residual-heat recovery is also faced with many problems in the popularization of steel industry.
Due to containing substantial amounts of dust in flue gas, there is dust stratification, clogging on heat exchange element in viscous and thin dust, no
Heat exchange efficiency is only influenced, causes waste heat boiler steam production insufficient, more seriously since waste heat boiler blocks up ash, system operation is not
Stablize, cause smelting production that can not be normally carried out, maintenance of being forced to stop production.
Simultaneously as the fluctuation of copper smelter flue-gas temperature is violent, wave amplitude is big, waste-heat recovery device must just design enough to
Greatly, it is ensured that high-temperature flue gas also can be cooled down effectively.But actual steam yield is far below the evaporation capacity of waste-heat recovery device, goes out
The situation of existing low load with strong power.This just relatively reduces the economic value of waste-heat recovery device, adds waste-heat recovery device
Investment.
It is usually air discharging machine beside deduster when deduster, exhaust tube are arranged apart, inflator of setting a raft going beside wind turbine, three
It must be connected by above-mentioned pipeline, shortcoming is in addition set Ventilator Room, landing exhaust tube and the connection between them
Pipeline, investment cost is high, take up a large area, resistance is high, power consumption is high.
