Abstract
The utility model relates to a moving vane-type steam turbine, which comprises a steam cylinder. A rotor and a rotating shaft are arranged in the steam cylinder; the rotor is provided with a radial floating vane; the outer end of the floating vane is abutted with the inner wall of the steam cylinder; the inner wall of the steam cylinder is provided with a floating spacer; one side of the floating spacer is provided with a steam inlet area provided with a steam inlet; and the other side of the floating spacer is provided with an exhaust area provided with a waste steam exhaust port. Steam in the steam cylinder inflows in the radial direction and is exhausted in the radial direction; the gas flow advancing direction is consistent with the rotating direction of the rotor all along, and no angular difference is generated, and therefore, the energy conversion efficiency is high, and the loss is low; the moment and the thrust face of the rotating shaft are greatly increased by the floating vane, and thereby, the energy consumption is low. The moving vane-type steam turbine has the advantages that the structure is simple; components are few; the equipment investment is low; and the mechanical energy loss is low. The moving vane-type steam turbine can work by using lower steam temperature and pressure, and thereby, the operating cost is saved.
Description
Technical field
The utility model relates to a kind of steam turbine, particularly a kind of movable blade type steam turbine.
Background technique
Steam turbine develops into present steam turbine engines by initial reciprocal feed pump; The kinetic energy of water vapor is converted into the kinetic energy of turbine rotation; Than compound steam engine; Steam turbine engines has significantly improved the thermal efficiency, is specially adapted to thermal power generation and nuclear energy power generation, and about in the world 80% electricity is to utilize turbine steam engine to produce.But prior steam turbogenerator complex structure; Vapor stream is an axial flow; And turbine radial force rotation the two 90 ° of angular differences appear, half that makes steam turns to axial idle work, itself also there are various energy losses such as impeller friction, stator blade resistance, gas leakage, air blast in machinery in addition; Cause the existing steam turbine engines thermal efficiency extremely low, and be difficult to overcome huge fuselage and vibration noise.
Summary of the invention
The purpose of the utility model provides a kind of movable blade type steam turbine, and simplified structure improves the thermal efficiency.
The utility model movable blade type steam turbine comprises and is provided with rotor and rotating shaft in steam cylinder, the cylinder, and rotor is provided with the radial floating blade, and float blade outer end and steam cylinder inwall offset; The steam cylinder inner wall is provided with unsteady barrier flaps, and barrier flaps one side of floating is an air inlet area, is provided with steam inlet, and opposite side is an exhaust area, is provided with the waste steam relief opening.
Said unsteady blade outer end is equipped with and is sealed the sheet that rises, and the inner is provided with spring.
Said unsteady barrier flaps the inner is provided with spring.
Said rotor had the segmental arc that radially reduces before the blade that floats.
Rotor is provided with one or more radial floating blades.
Can comprise a plurality of steam cylinders, the rotor coaxial series connection in each cylinder.
The utility model steam turbine is power source with the saturated vapour, after saturated vapour feeds air inlet area, because of volumetric expansion; Pressure reduces; Flow velocity increases, and the steam of expansion directly acts on unsteady blade with the tangent direction of rotor, and blade drives rotor and rotating shaft rotation work done.The advantage of this machine is, steam is radial air inlet and radially exhaust in cylinder, goes into behind the cylinder until arriving exhaust area, and the vapor stream direction of advance is consistent with the rotor sense of rotation all the time, has no angular difference, so energy conversion efficiency is high, and loss is lacked; Rotor installs blade additional, and the face of being pushed away is increased, and has strengthened torque; This steam turbine is simple in structure, and parts are few, and not only equipment investment is low, and the mechanical energy loss is few, therefore only needs to get final product work with lower vapor (steam) temperature and pressure, saves operating cost.This machine inertial force is little, applicable to the needs of different rotating speeds, when being used at a slow speed the terminal, need not huge speed reducer, when load stops suddenly, can slow down very soon.
In sum, the utility model steam turbine
Description of drawings
Fig. 1 is the cross-sectional view of this movable blade type steam turbine.
Among the figure, 1-cylinder, 2-rotor, 2-1-be segmental arc decrescence radially, the 3-rotating shaft, and 4, the 10-spring, the 5-blade that floats, the 6-sheet that rises, the 7-steam inlet, the 8-air inlet area, the 9-spacer that floats, 11-waste steam relief opening, L-breaks out the district, the 12-exhaust area.
Embodiment
Like Fig. 1, be provided with concentric rotor 2 and rotating shaft 3 in the steam cylinder 1, rotor 3 is provided with radial floating blade 5, and the sealing sheet 6 that rises is equipped with in blade 5 outer ends of floating, and the inner is provided with spring 4, makes blade 5 outer ends of floating be tight against the inwall of steam cylinder 1 and and through sheet 6 sealings of rising.Steam cylinder 1 inwall is provided with the barrier flaps 9 of floating, and the barrier flaps the inner of floating is provided with spring 10, and it makes the barrier flaps 9 of floating offset with rotor 2.One side of the barrier flaps 9 of floating is an air inlet area 8, and opposite side is an exhaust area 12; Air inlet area 8 is provided with steam inlet 7, and exhaust area 12 is provided with waste steam relief opening 11.Rotor has radially segmental arc 2-1 decrescence in the front side of the blade that floats.
This machine is gone into the air inlet area 8 of cylinder 1 from the saturated vapour of Boiler Steam bag by steam inlet 7, and its volume expands suddenly, and pressure reduces, and flow velocity increases.The steam that expands directly acts on the blade 5 that floats with the tangent direction of rotor 2, thereby drives rotor 2 and rotating shaft 4 rotation works done.The front side high velocity vapor stream that receives of unsteady blade 5 promotes, and makes rotor 2 fast rotational, pushes the steam of its rear side to exhaust area simultaneously, discharges waste steam from waste steam relief opening 11.When rotor 2 because of action of inertia, after through waste steam relief opening 11, still continue rotation and cross spacer 9 to arrive air inlet area 8, the vapor stream that is inflated once more promotes, and so continuously rotates work done.
