Description
Technical field
The utility model is related to heat power engineering, quench slag steam electric power generator more particularly to a kind of blast furnace.
Background technology
China is the big country of steel production, and the annual output of steel accounts for the 40% of Gross World Product.Either steel-making or refining
Iron will generate a large amount of clinker.Clinker is accompanied generation with steel, it is the byproduct of smelting iron and steel.
In Ferrous Metallurgy stove, 1400-1500 DEG C of high temperature furnace slag is generated, enters flushing cinder after cinder notch flows out, then through slag runner
When chute, with certain water, hydraulic pressure and the chute gradient, make water with slag stream at certain angle of cut, slag is burst by cold shock
At the qualified grain slag of certain particle size.
After pulp water separation, clinker is used as construction material；The washing slag water that heat exchange is carried out with high temperature furnace slag, into washing slag water
Pond, a large amount of steam that slag of quenching generates are fallen by steam smoke stack emission, and slag steam heat of quenching is about high temperature furnace slag net quantity of heat
60%.
Flushing cinder pond usually takes up an area thousands of square metres, and hot vapour is emptied above flushing cinder pond, and flushing cinder coolant-temperature gage is maintained at throughout the year
70-80 DEG C, be a huge potential thermal energy energy, if can effectively be used, such as utilizes the heat of washing slag water
Can, winter heats for residential block, can be not only that country saves a large amount of fuel, but also reduces carbon emission, protect environment.
Steel mill's blast furnace often smelts 1 ton of pig iron, and the heat that clinker loses accounts for total amount of heat income in 0.81GJ~0.87GJ
6.61%~7.5%, signature coal is the heat that 27.77kg~29.78kg burnings are released, and is calculated with slag ratio 0.44, slag damage per ton
The heat of mistake is about the heat that 63.9kg mark coal completely burneds are released.
Currently, it is mainly exhaust heat of slag flushing water recycling in terms of blast furnace slag heat recycling, is mainly used for the list for heating, having utilized
Position such as Shoudu Iron and Steel Co, Ji steel, Xuan Gang, Anshan iron and steel plant, this steel, Laigang, An Gangdeng enterprises.And it accounts for high temperature furnace slag net quantity of heat 60% and quenches slag steam
Heat is not utilized also completely at present.
Utility model content
In order to fully recycle blast furnace slag heat, the utility model provides a kind of blast furnace and quenches slag steam electric power generator.
A kind of blast furnace is quenched slag steam electric power generator, its overall structure includes：Chimney, power generation box, generator and condenser.
Power generation box is made of babinet, shaft, turbine；Condenser is by cylinder, cooling water coil, cooling water inlet, cooling water
Outlet, vacuum pump and suction pump are constituted.
The slag steam of quenching come from flushing cinder pond enters chimney, and slag steam of quenching horizontally enters into power generation box after reaching chimney top, pushes away
After dynamic electrical power generators, slag steam of quenching is downwardly into condenser condensation.
The power generation box, its box shape are in revolving body, are horizontally arranged, and in center enlargement, inner horizontal is placed
One end of shaft and turbine, shaft stretches out power generation box and the spindle nose of generator connects.
The condenser, its cylinder are the tubular equipment placed vertically, and internal cooling water coil rises in flat spin
Shape, quench slag steam after the condensation heat of cooling water coil surface to lower drippage, in condenser bottom, condensed water is by the pumping on cylinder
Water pump is taken away；The air that slag steam of quenching carries, is taken away by the vacuum pump on cylinder.
Description of the drawings
Fig. 1 is that the utility model blast furnace is quenched slag steam electric power generator embodiment overall pattern.
Specific implementation mode
With reference to the accompanying drawings and examples, the utility model is described in further detail.
Fig. 1 gives the utility model blast furnace and quenches slag steam electric power generator embodiment overall pattern.
The utility model blast furnace is quenched slag steam electric power generator embodiment, its overall structure includes：Chimney 10, power generation box
20, generator 30 and condenser.
Power generation box 20 is made of babinet 21, shaft 22, turbine 23.
Condenser is by cylinder, cooling water coil 50, cooling water inlet 51, cooling water outlet 52, vacuum pump 61 and suction pump
62 are constituted.
The slag steam of quenching come from flushing cinder pond, by chimney air intake 11, into chimney 10, from bottom to top ascension.Slag of quenching steams
After vapour reaches chimney top, power generation box 20 is horizontally entered into.
21 shape of babinet of power generation box 20 is in revolving body, is horizontally arranged, and central part expands, and inner horizontal places turbine 23
With shaft 22.Slag Steam Actuation turbine 23 and the shaft 22 of quenching rotate, and power generation box 20 is stretched out in one end of shaft 22, with generator 30
Spindle nose connection, drive electrical power generators.After slag steam quench by power generation box, it is downwardly into condenser.
The cylinder of condenser is the tubular equipment placed vertically, and there is a cooling water coil 50 in inside, outer surface have cooling water into
Mouth 51, cooling water outlet 52.Slag steam quench in 50 surface condensation heat of cooling water coil, condensed water drips downwards, in condenser
Bottom is accumulated, and is then taken away by the suction pump 62 on the cylinder of condenser bottom.It quenches and carries some air in slag steam, by steam
It takes condenser bottom to, is then taken away by the vacuum pump 61 on the cylinder of condenser bottom.
