The turbine booster set at least comprises a turbine (1) and a gas pressure converting mechanism, wherein the turbine (1) and a motor shaft of the gas pressure converting mechanism constitute a coaxial body through a shaft coupling (7); low-pressure air (6) is communicated with the input end of the gas pressure converting mechanism; high-pressure blast furnace coal gas (4) is communicated with the input end of the turbine (1); and tail gas of the high-pressure blast furnace coal gas is used for driving the turbine (1) to rotate, so that residual pressure of the tail gas of the high-pressure blast furnace coal gas (4) can be converted into rotation mechanical energy, and the rotation mechanical energy is converted into gas pressure through the gas pressure converting mechanism arranged coaxially with the turbine (1) for acting on a blast furnace.
Description
Technical field
The present invention relates to Iron And Steel Plant's blast-furnace top gas recovery and reclaim the field, be specifically related to a kind of turbine supercharging unit that the blast furnace tail gas energy reclaims that is used for.
Background technology
Present domestic reaching in the world drives blast-furnace top gas recovery the generator for electricity generation use and reduces the motor load use with compressor as coaxial unit through being mainly used in after the energy recycle device recovery.The former can be converted into electric energy output through turbo-expander and generator with the blast furnace overbottom pressure that reclaims and utilize, and it is to reduce the load of phonomoter that the latter can replenish the blast furnace overbottom pressure that reclaims to compressor shaft through the mechanical energy that decompressor is converted into rotation.The function of these two kinds of structures all is that the blast furnace overbottom pressure can be recycled, but the performance that how much depends on former blast furnace of recovered energy, these two kinds of structures do not produce any change to original configuration of blast furnace.Secondly; The employed compressor of blast furnace generally all disposes two covers; These two the cover unit when blast furnace runs well one normally move as main frame; Reserve machine used when another broke down as main frame, so the user all need order two covers when ordering the complete unit of compressor at every turn, caused cost of investment to strengthen.
Summary of the invention
For overcoming the shortcoming that above-mentioned prior art exists, the present invention provides a kind of ability saves energy and the turbine supercharging unit that is used for the energy recovery of blast furnace overbottom pressure that has reduced the running cost of blower fan unit.
The objective of the invention is to realize like this; A kind of turbine supercharging unit that is used for the recovery of blast furnace tail gas energy; It is characterized in that: which comprises at least: turbo 1, air pressure throw-over gear; Turbo 1 forms same axis body with air pressure conversion rotation mechanism motor shaft through shaft coupling 7, and low-pressure air 6 links with the input terminus of air pressure throw-over gear, and is same; High pressure blast furnace gas 4 links with the input terminus of turbo 1; Blow turbo 1 rotation through high pressure blast furnace gas tail gas and do manual work, can convert the overbottom pressure of high pressure blast furnace gas tail gas the mechanical energy of rotation into, the mechanical energy of rotation can act on the blast furnace through the pressure that the 1 coaxial mounted air pressure throw-over gear with turbo converts gas into.
Described air pressure throw-over gear is compressor.
Described air pressure throw-over gear is the gas blower of low pressure.
Advantage of the present invention is: propulsion source of the present invention is the overbottom pressure of high furnace exhaust gas; Blowing turbo through tail gas does manual work; Can convert overbottom pressure the mechanical energy of rotation into, the mechanical energy of rotation through with the coaxial mounted compressor of turbo convert into gas pressure can, finally act on the blast furnace.This kind structure drops into blast furnace system and uses at the alternative high pressure compressor of the gas blower that is equipped with low pressure.And this kind structure does not consume any electric energy, than existing unit save energy greatly.
Below in conjunction with the embodiment accompanying drawing the present invention is described further:
Description of drawings
Fig. 1 is the structural representation for embodiments of the invention 1;
Fig. 2 is the structural representation for embodiments of the invention 21;
Among the figure, 1, turbo 2, compressor 3, low-blast furnace coal gas 4, high pressure blast furnace gas 5, high-pressure air; 6, the gas blower of low-pressure air 7, shaft coupling 8, low pressure.
Embodiment
As shown in Figure 1; A kind of turbine supercharging unit that is used for the recovery of blast furnace tail gas energy; Which comprises at least: turbo 1, compressor 2, turbo 1 forms same axis body with compressor 2 through shaft coupling 7, and low-pressure air 6 links with the input terminus of compressor 2; High pressure blast furnace gas 4 links with the input terminus of turbo 1; Blow turbo 1 rotation through high pressure blast furnace gas tail gas and do manual work, can convert the overbottom pressure of high pressure blast furnace gas tail gas the mechanical energy of rotation into, the mechanical energy of rotation can act on the blast furnace through the pressure that converts gas into turbo 1 coaxial mounted compressor 2.
As shown in Figure 2; Different with embodiment 1 is; A kind of turbine supercharging unit that is used for the recovery of blast furnace tail gas energy which comprises at least: the gas blower 8 of turbo 1, low pressure, and gas blower 8 motor shafts of turbo 1 and low pressure form same axis body through shaft coupling 7; Low-pressure air 6 links with the input terminus of the gas blower of low pressure; Equally, high pressure blast furnace gas 4 links with the input terminus of turbo 1, blows turbo 1 rotation through high pressure blast furnace gas tail gas and does manual work; Can convert the overbottom pressure of high pressure blast furnace gas tail gas the mechanical energy of rotation into, the mechanical energy of rotation can act on the blast furnace through the pressure that the gas blower 8 with turbo 1 coaxial mounted low pressure converts gas into.
The present invention has and does not consume any electric energy, than existing unit save energy greatly.
1), having solved the user need order two covers one simultaneously and touch the same unit, the problem that cost of investment is big when ordering blower fan.The user can order a cover unit according to the required flow of blast furnace, pressure and other parameters and use as reserve machine; Satisfy the blast furnace demand at order one cover flow in addition; The blower fan that pressure is lower; Be equipped with the turbine supercharger group system that is used for the energy recovery of blast furnace overbottom pressure, can satisfy required traffic requirement of blast furnace and pressure requirement.And blast furnace pressure can be regulated as required after disposing this machine set system.
2), practiced thrift electric energy, reduced the running cost of blower fan unit.This supercharging system can directly be replenished the overbottom pressure that reclaims to blast furnace with the pressurize mode, has reduced the waste between energy transformation.This unit can be used as the main frame life-time service, and because of this system consuming any energy source but can be the blast furnace supercharging not, its running cost will significantly reduce.
