The secondary mixed wind of line air intake form.
Specific technological process is as follows：The pig iron or iron filings are put into by charge door melting is carried out in furnace cupola, due to
Furnace cupola air intake arranges that the reducing atmosphere in stove is stronger, and the Co contents in furnace gas reach 15%-18%, stove using single air outlet
The temperature of gas is at 300 DEG C or so.Furnace gas is flowed into above furnace cupola in the first flue, is filled by combustion fan and mixed wind
Put and furnace gas and combustion air are subjected to mixed wind for the first time, furnace gas, due to using tangent line air intake form, makes when entering in combustion chamber
Furnace gas rotates to form second of mixed wind, preheated furnace igniting burning after combustion chamber is entered along inwall, and such flue-gas temperature rises
To 950 DEG C -1000 DEG C or so, 900 DEG C or so then are cooled to by cold wind blower fan, then high-temp waste gas is flowed into heat exchange
In the hot wind inlet of device.
Meanwhile the cold wind sent by air blower is entered in heat exchanger cold wind import, it is with entering exchanger heat wind inlet
High-temp waste gas exchanged heat in heat exchanger, cold wind is 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, is then entered in the hot wind inlet of furnace cupola, made in furnace cupola by warm-air pipe
Smelting temperature up to more than 1800 DEG C, the molten iron of fusing goes out from preceding packet stream.Because the raising of smelting temperature in stove is advantageous 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 out of furnace cupola and set when flowing through combustion chamber, heat exchanger, big water cooler, small water cooler due to above-mentioned
Standby bottom is designed with ash dropping cylinder, therefore heavier particulate matter obtains processing and collected, and waste gas is through big water cooler and small water cooler
It is flowed into after cooling treatment in sack cleaner and carries out dust removal operation, is entered finally into spray desulfurizer, spray desulfurization dress
The effect put is that the sulfur dioxide in waste gas is combined to 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 into spray thrower,
Spraying and dedusting operation is carried out to waste gas, then the water of spray desulfurizer outflow is flowed into the first pond, is finally flowed into second
Recycled in pond.
Further, it is explosion-proof that aluminium film is provided with the second fume pipe, the 3rd fume pipe, the 4th fume pipe, sack cleaner
Valve, this is due to may also have part coal gas in waste gas, prevents pipeline breaking.
Its main function of gas bleeding valve is to pass through the residual gas in combustion chamber, heat exchanger in furnace cupola damping down
Gas bleeding valve emits, and then ensures security when furnace cupola uses.
The examining report of wherein waste water is as follows：
Stove waste gas (waste gas discharged from chimney) examining report is as follows：
The discharge standard of waste water and waste gas is below international standard as from the foregoing.
Energy-saving, environment-friendly and high-efficiency blast-heating cupola of the present utility model, there is advantages below：First, it can be by the pig iron and iron
Bits are turned into molten iron, while the molten iron temperature generated is 1560 DEG C, high purity, is needed in the case of molten iron temperature identical
Coke is few, and so as to reach the effect of energy-conservation, transformation efficiency is high；Secondly, waste gas caused by furnace cupola first pass through big water cooler and
Small water cooler is collected, then passes sequentially through sack cleaner and spray desulfurizer progress dust removal operation, and last is harmless
Waste gas flows out from chimney, to outside environmental nonpollution, has higher practicality and promotional value, meets the development in China and needs
Will.
