Further, air mixing device is also equipped with the first fume pipe, the first fume pipe is adopted with combustor lower inlet and cut
The secondary mixed wind of line air intake form.
Specific technological process is as follows：The pig iron or iron filings is put into by charge door and carry out in furnace cupola melting, due to
Furnace cupola air intake arranges that the reducing atmosphere in stove is stronger using single air outlet, and the Co contents in furnace gas reach 15%-18%, stove
The temperature of gas is at 300 DEG C or so.Furnace gas is flowed in the first flue from furnace cupola top, is filled through combustion fan and mixed wind
Put carries out mixed wind for the first time by furnace gas and combustion air, and furnace gas is when indoor into burning due to using tangent line air intake form, making
Furnace gas is rotating to form second mixed wind into combustor tailing edge inwall, and preheated furnace igniting burning, such flue-gas temperature rises
To 950 DEG C -1000 DEG C or so, then 900 DEG C or so are cooled to by cold wind blower fan, then high-temp waste gas are flowed into heat exchange
In the hot wind inlet of device.
Meanwhile, the cold wind sent by aerator is entered in heat exchanger cold wind import, its with into exchanger heat wind inlet
High-temp waste gas exchanged heat in heat exchanger, make cold wind be changed into high-temperature hot-air, hot blast temperature up to 450 DEG C -500 DEG C or so,
Hot blast flows out from the hot-blast outlet of heat exchanger, in then passing through the hot wind inlet that warm-air pipe enters into furnace cupola, makes in furnace cupola
Smelting temperature up to more than 1800 DEG C, molten iron the past packet stream of fusing goes out.Because the raising of smelting temperature in stove is conducive to molten iron
In desulfuration in furnace, degasification and slag sluicing system, molten iron temperature is up to 1560 DEG C or so.Due to the degree of purity of the high molten iron of molten iron temperature
Height, under conditions of identical molten iron temperature is reached, required coke is few, and so as to reach the effect of high-quality energy-conservation, transformation efficiency is high；By
In molten iron temperature up to 1560 DEG C or so, so iron filings also melting can be fallen.
Flue gas is drawn from furnace cupola and set due to above-mentioned when flowing through combustor, heat exchanger, big water cooler, little water cooler
Standby bottom is designed with ash dropping cylinder, therefore heavier particulate matter obtains processing collection, the big water coolers of waste gas Jing and little water cooler
Being flowed into after cooling treatment in sack cleaner carries out dust removal operation, in entering finally into spray desulfurizer, spray desulfurization dress
The effect put is that the sulfur dioxide in waste gas is combined into transmission reaction with water so that sulfur dioxide is not discharged into air, finally
Remainder of exhaust gas flows out from chimney.
Wherein, when spray desulfurizer works, water pump is started working, and the water in the second pond is flowed in spray thrower,
Spraying and dedusting operation is carried out to waste gas, the water that then spray desulfurizer flows out is flowed in the first pond, is finally flowed into second
It is circulated in pond and uses.
Further, it is provided with aluminium film in the second fume pipe, the 3rd fume pipe, the 4th fume pipe, sack cleaner explosion-proof
Valve, this is due to also having part coal gas in waste gas, prevent pipeline breaking.
Gas bleeding valve its Main Function is to pass through the residual gas in combustor, heat exchanger in furnace cupola damping down
Gas bleeding valve is emitted, and then safety when ensureing that furnace cupola is used.
The examining report of wherein waste water is as follows：
Stove waste gas (waste gas discharged from chimney) examining report is as follows：
As from the foregoing the discharge standard of waste water and waste gas is below international standard.
The energy-saving, environment-friendly and high-efficiency blast-heating cupola of the present invention, with advantages below：First, it can be equal by the pig iron and iron filings
It is turned into molten iron, while the molten iron temperature for generating is 1560 DEG C, high purity, the coke needed in the case of molten iron temperature identical
Few, so as to reach the effect of energy-conservation, transformation efficiency is high；Secondly, the waste gas that furnace cupola is produced first passes through big water cooler and little Shui
Cooler is collected, then passes sequentially through sack cleaner and spray desulfurizer and carry out dust removal operation, last harmless exhaust gases
Flow out from chimney, to outside environmental nonpollution, with higher practicality and promotional value, meet the development need of China.
The above is only the concrete application example of the present invention, protection scope of the present invention is not limited in any way.All employings
Equivalents or equivalence replacement and the technical scheme that formed, all fall within rights protection scope of the present invention.
