Detailed description of the invention

Now 1 the utility model is described in further detail by reference to the accompanying drawings:

As shown in drawings, a kind of device utilizing aerial cooler hot blast, it is characterized in that: comprise aerial cooler, axial flow blower, anode furnace, side direction gas skirt, air blast, control valve, electric butterfly valve, flow detector, surrounding air enters aerial cooler 1 cooling furnace kiln high-temperature flue gas under the effect of axial flow blower 2 appended by aerial cooler 1, and flue-gas temperature drops to about 150 DEG C from 360 DEG C.The temperature of surrounding air rises to about 100 DEG C from normal temperature, and by the unified collection of side direction gas skirt 3, is sent to anode furnace burner 12, and assists burning under the effect of air blast 6 in anode furnace 13 stove.

If the hot blast rate helping combustion air consumption to produce more than aerial cooler 1 that anode furnace 13 needs, on pipeline before anode furnace burner 12, flow detector 14 controls front control valve 4 and opens and regulate, after controlling, control valve 11 cuts out simultaneously, to mix part from helping combustion air in ambient air.

If what anode furnace 13 needed helps combustion air consumption to be less than the hot blast rate of aerial cooler 1 generation, on pipeline before anode furnace burner 12, flow detector 14 controls front control valve 4 and closes, after controlling, control valve 11 is opened and regulates simultaneously, helps combustion air in ambient air with emptied part.

Be front electric butterfly valve 5 under normal operative condition, rear electric butterfly valve 7 opens, air blast 6 runs, and front electric butterfly valve 8 for subsequent use, rear electric butterfly valve 10 for subsequent use and emergency blower 9 are closed.When air blast 6 fault, front electric butterfly valve 5 and rear electric butterfly valve 7 are closed, and front electric butterfly valve 8 for subsequent use, rear electric butterfly valve 10 for subsequent use are opened, and emergency blower 9 runs, to realize the switching helping combustion air various flows circulation passage.

The combustion air consumption blasted with technique stove anode furnace is for 10000Nm ³/ h is example, can produce about 11000Nm ³/ h, the high-temperature flue gas of 1250 DEG C.This high-temperature flue gas is by after once cooling, and exhaust gas volumn is increased to 11550Nm ³/ h, flue-gas temperature reduces to about 360 DEG C, then enters the further cooling down of aerial cooler, and flue-gas temperature reduces to about 150 DEG C from 360 DEG C.Meanwhile, about 37000Nm can be produced ³/ h, the hot blast that temperature is about 100 DEG C.Under the effect of air blast, this hot blast is sent to the combustion-supporting burning of technique stove anode furnace, the used heat in hot blast both can have been utilized to save fuel, the thermal pollution to ambient air can be reduced again.

Draw as calculated, adopt the hot blast of temperature about 100 DEG C to compare with normal temperature air, anode copper fuel saving per ton amounts to 6.5kgce, be that 600 yuan/t calculates by mark coal unit price, produce the smeltery of 300,000 tons of anode copper scales per year, about 1,170,000 yuan can be saved every year, there is significant economic benefit.

Above content is in conjunction with concrete preferred embodiment further detailed description of the utility model, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field; make some equivalent alternative or obvious modification without departing from the concept of the premise utility; and performance or purposes identical, then should be considered as belonging to the protection domain that claims that the utility model submits to are determined.
