Description
Technical field：
The invention belongs to steam turbine equipment technical field, and in particular to a kind of drawing-in type of high-power saturation steam turbine strengthens dehumidifying
Structure.
Background technology：
Moisture in moist steam brings many influences to the operation of steam turbine, and the size water droplet that moist steam is formed is to Turbine Steam
Cylinder interior generation, which is hit even, to be occurred corroding, situation about corroding occurs to stator blade and movable vane generation chemistry and mechanism, especially
It is the etching problem of final stage leaf grating, will significantly reduces service life.It can also increase steam turbine load in addition, influence the power of the assembling unit.
Current large steam turbine space peculiar to vessel is limited, and simply dehumidifying measure can not effectively remove the water in these steam
Point, drawing-in type strengthens dehumidification structure and effectively completes internal moisture removal in cylinder internal, for arrangement other equipment on ship save compared with
Large space, and erosion and impact to blade and cylinder are reduced, increase steam turbine life-span and power.
The content of the invention：
The present invention is made up and improved in place of above-mentioned the deficiencies in the prior art, there is provided a kind of suction of high-power saturation steam turbine
Formula strengthens dehumidification structure, effectively completes internal moisture removal in cylinder internal, and larger space is saved for arrangement other equipment on ship,
And erosion and the impact to blade and cylinder are reduced, and increase steam turbine life-span and power, it is reasonable in design, securely and reliably,
Cost is cheap, is easy to promote and use on a large scale.
The technical solution adopted by the present invention is：A kind of drawing-in type of high-power saturation steam turbine strengthens dehumidification structure, including
Cylinder body, in addition to hydrophobic linker and hydrophobic linker group；The cylinder body bottom is provided with weep hole, the hydrophobic linker position
In the big dehumidifying level bottom of carrying capacity；The hydrophobic linker group is located at the small dehumidifying level bottom of carrying capacity.
Further, the hydrophobic linker is provided with bellmouth orifice.
Further, the hydrophobic linker is welded on cylinder body.
Further, the hydrophobic linker group includes pipe joint and ring.
Further, four uniform inlet openings are provided with the top of the pipe joint, its bottom is provided with six uniformly hydrophobic
Hole.
Further, the diameter of the weep hole is more than the diameter of inlet opening.
Further, passage is provided between the inlet opening and weep hole.
Beneficial effects of the present invention：Reasonable in design, securely and reliably, cost is cheap, is easy to promote on a large scale and makes
With.The drawing-in type for providing a kind of high-power saturation steam turbine strengthens dehumidification structure, including weep hole, hydrophobic linker, hydrophobic connects
Head group.Internal moisture removal effectively is completed in cylinder internal, larger space is saved for arrangement other equipment on ship, and is reduced pair
The erosion and impact of blade and cylinder, increase steam turbine life-span and power.Hydrophobic linker group is by pipe joint and ring group into the work of ring
With being to prevent steam water interface from flashing.The inlet opening aperture of pipe joint is smaller, and uniform at four sides, centre has runner to lead to bottom six
Individual uniform weep hole.Weep hole is bigger than inlet opening, can so ensure that flow velocity is very slow, in the case of water-filled in runner, vapour
Body just can not be by, can so play the effect of sealing.

Embodiment：
With reference to each figure, a kind of drawing-in type of high-power saturation steam turbine strengthens dehumidification structure, including cylinder body, in addition to hydrophobic
Joint 2 and hydrophobic linker group 3；The cylinder body bottom is provided with weep hole 1, and the hydrophobic linker 2 is located at that carrying capacity is big to be removed
Wet level bottom；The hydrophobic linker group 3 is located at the small dehumidifying level bottom of carrying capacity；The hydrophobic linker 2 is welded in cylinder body
On；The hydrophobic linker group 3 includes pipe joint 4 and ring 5；The top of pipe joint 4 is provided with four uniform inlet openings 7, its bottom
Portion is provided with six uniform weep holes 6；The diameter of the weep hole 6 is more than the diameter of inlet opening 7；The inlet opening 7 and hydrophobic
Passage is provided between hole 6.
The dehumidification structure, including weep hole 1, hydrophobic linker 2, hydrophobic linker group 3；Weep hole 1 is arranged in cylinder lower, is led to
Cross to establish pressure difference and realize and draw gas and large quantity of moisture of going further simultaneously；Added in rate of air sucked in required considerable influence power or the level that need not be evacuated
Hydrophobic linker group 3, stop gas.Hydrophobic linker group 3 includes pipe joint 4 and ring 5 again.By thermodynamic computing, determine which rank of is needed
Weep hole is wanted, arranges weep hole 1 in cylinder lower half, aperture is determined by thermodynamic computing；Dredged in the larger dehumidifying level arrangement of carrying capacity
Water swivel 2, flow velocity is reduced, hydrophobic linker 2, which needs to be welded, to be fixed；Mainly needing start and stop hydrophobic, during operation carrying capacity it is few or
Not hydrophobic level arrangement hydrophobic linker group 3.
