At the process of electric energy lossy, electricity and network process it is lossy, recycling electricity by the main motor for blower by electric energy turn
It is lossy to be melted into mechanical energy process；
The power generation process of TRT and grid-connected process device need invest and control it is relatively complicated, for recycle total energy
Small blast furnace is measured, investment return is than less desirable, therefore many small furnaces (about 1000 cubic metres of volume and blast furnace below) are no
Using TRT, the recoverable energy in this part is caused to waste.
Summary of the invention
In order to overcome form conversion twice is carried out after energy regenerating in the prior art recycle, to reduce recycling
Rate increases power generation and the investment of electric grid-connection device, increases the defects of control difficulty, and the present invention provides a kind of blast furnace air feed and high
The integral type electromechanical equipment of producer gas overbottom pressure energy regenerating has the blast furnace gas of overbottom pressure to pass through the mechanical energy that turbine generates, and leads to
The main shaft that one-way clutch is directly passed to blast furnace air feed main motor is crossed, realizes to recover energy and be transmitted simultaneously in the form of mechanical energy
It utilizes.
The technical solution adopted by the present invention to solve the technical problems is: a kind of blast furnace is integrated for air gas hydraulic recovery
Machine, including for blower, gearbox, for blower barring gear, air feed main motor, one-way clutch, turbine, reduction gearbox, turbine
Machine barring gear, catcher, connecting shaft.
Above-mentioned blast furnace is described for blower fan main shaft and gearbox speed end main gear shaft for air gas hydraulic recovery all-in-one machine
One end by connecting shaft be connected, the other end of the gearbox speed end main gear shaft passes through with for blower barring gear main shaft
Catcher is connected, described to constitute coaxial one.
Above-mentioned blast furnace is for air gas hydraulic recovery all-in-one machine, the air feed main motor main shaft and gearbox low speed end tooth wheel
One end of main shaft is connected by catcher, and the other end of gearbox low speed end main gear shaft is stretched for axis, in one-way clutch
Ring is assembled, and the outer ring of the one-way clutch is connected with reduction gearbox low speed end main gear shaft by catcher, described to constitute together
Axis two, the outer ring of the one-way clutch is drive end, inner ring is driven end.
Above-mentioned blast furnace is for air gas hydraulic recovery all-in-one machine, the turbine spindle and reduction gearbox speed end main gear shaft
One end by connecting shaft be connected, the other end of the reduction gearbox speed end main gear shaft passes through with turbine barring gear to be connect
Axis is connected, described to constitute coaxial three.
The invention has the advantages that integral type electromechanical equipment of the invention, the blast-furnace top gas recovery energy of recycling with
The form of mechanical energy passes to air feed main motor main shaft by one-way clutch and is directly utilized, and avoids traditional technology handle and returns
Receive energy carry out two form of degree n n conversion recycle and caused by be lost, improve energy regenerating utilization rate；Power generation is eliminated simultaneously
And the equipment investment that electricity is grid-connected, simplify corresponding control.
Detailed description of the invention
Present invention will be further explained below with reference to the attached drawings and examples.
Fig. 1 is schematic diagram of the present invention.
1. for blower in figure, and 2. gearboxes, 3. for blower barring gear, and 4. air feed main motors, 5. one-way clutch, 6. thoroughly
Flat machine barring gear, 7. reduction gearboxes, 8. turbines.
Specific embodiment
[embodiment 1]
Blast furnace is for air gas hydraulic recovery all-in-one machine, including for blower 1, gearbox 2, for blower barring gear 3, air feed master
Motor 4, one-way clutch 5, turbine 6, reduction gearbox 7, turbine barring gear 8, catcher, connecting shaft.For 1 main shaft of blower and increase
One end of fast 2 speed end main gear shaft of case by connecting shaft be connected, the other end of 2 speed end main gear shaft of gearbox with for blower
3 main shaft of barring gear is connected by catcher, constitutes coaxial one；4 main shaft of air feed main motor and 2 low speed end main gear shaft of gearbox
One end is connected by catcher, and the other end of 2 low speed end main gear shaft of gearbox is stretched for axis, is filled with 5 inner ring of one-way clutch
Match, the outer ring of one-way clutch 5 is connected with 7 low speed end main gear shaft of reduction gearbox by catcher, constitutes coaxial two, one-way clutch
5 outer ring is drive end, inner ring is driven end；8 main shaft of turbine passes through with one end of 7 speed end main gear shaft of reduction gearbox to be connect
Axis is connected, and the other end of 7 speed end main gear shaft of reduction gearbox is connected with 6 main shaft of turbine barring gear by connecting shaft, constitutes
Coaxial three.
[embodiment 2]
In above-mentioned " embodiment 1 ", one-way clutch 5 can also be using freewheel clutch or holdback or other shapes
The clutch or unilateral bearing of formula or other similar devices realize the transmitting of mechanical energy.
[embodiment 3]
It in above-mentioned " embodiment 1 " and " embodiment 2 ", uses three and is coaxially connected, can also be coaxially connected using two

The working principle of the invention:
Blast furnace passes through the mechanical energy that turbine generates for air gas hydraulic recovery all-in-one machine, the blast furnace gas for having overbottom pressure
Blast furnace air feed main motor, load that is described thus reducing air feed main motor are directly passed to by " one-way clutch ".
Further, when the blast furnace furnace lifting, " one-way clutch " is in discrete state, it is described at this time for blower by
The driving of air feed main motor, the turbine are generated without mechanical energy.
Further, when the blast furnace just brings into operation, the turbine starts low speed jiggering, described with passing through turbine
The blast furnace coal tolerance for having overbottom pressure of machine from scratch, described and gradually dosage；The turbine is detached from jiggering state and gradually adds
Speed, when the revolving speed increases to identical as the rotating speed of transmission shaft for the air feed system being connected, " one-way clutch " is by separating
State switchs to bonding state, described and start to transmit mechanical energy, and described while air feed main motor load accordingly reduces.
Further, when the blast furnace operates normally, described larger by the blast furnace coal tolerance for having overbottom pressure of turbine, institute
" one-way clutch " is stated always in bonding state, and the rotation speed is remained with the transmission shaft for the air feed system being connected
Identical, the quantitative value of the mechanical energy by turbine generation, one-way clutch transmitting is larger, and the air feed main motor load subtracts
It is morely small；The air feed main motor is in " underload " operating status.
Further, when the blast furnace staying, the blast furnace coal tolerance gradually decreased through turbine is not until have, institute
It states turbine to slow down until static, " one-way clutch " switchs to discrete state by bonding state, described at this time air feed master
Decelerating through motor simultaneously stops.
