Abstract
A dedusting and desalting injection mechanism for a turbine movable blade comprises a spray hole formed in an inner shell of a turbine stationary blade and a spray pipe connected with the spray hole, wherein the spray hole is positioned in front of the movable blade, and the distance b between the axis of the spray hole and the outer side of the movable blade is 20-80 mm. The injection mechanism can be arranged in front of the first stage or the first few stages of movable blades according to requirements, and each stage of movable blades is provided with one injection hole. The aperture of the spray hole is 3 mm-8 mm, and the inner diameter of the spray pipe is 10 mm-20 mm. The connection mode of the spray pipe and the spray hole is preferably threaded connection. By using the injection mechanism, the movable blades can be efficiently cleaned when the turbo machinery runs, so that the channel blockage is avoided, and the unit can run efficiently.
Description
Technical field
The utility model relates to a kind of mechanism of cleaning turbine rotor vane.
Background technique
Promote the working medium of large-scale turbomachinery rotation, often dust content composition big or salt is more, thereby dust stratification or analyse salt easily on each moving vane; cause passage to stop up; cause the unit can't high-efficiency operation, even overhauled the dust stratification on the water flushing moving vane by forced-stopping machine.Practice shows that main frame is taken off lid maintenance trouble, and the time of delaying is longer.Especially under the situation that dust content composition very big or salt is very many in the working medium, the cycle of shutting down maintenance is very short, can bring bigger economic loss to the user.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of dedusting desalination injection equipment of turbine rotor vane is provided, and this kind mechanism can carry out automatical and efficient cleaning to movable vane when turbomachinery moves.
The dedusting desalination injection equipment of turbine rotor vane described in the utility model comprises that spray orifice of offering on the turbine stator blade inner housing and the jet pipe that is connected with spray orifice, spray orifice are positioned at before the movable vane and the spray orifice axis is 20mm～80mm apart from the distance b outside the movable vane.
Described injection equipment can be provided with before the first order or preceding what movable vane as required, and each grade movable vane is provided with a spray orifice.The aperture of spray orifice is 3mm～8mm, and the internal diameter of jet pipe is 10mm～20mm.The Placement of jet pipe and spray orifice has various ways, but preferably is threaded.
In the unit operation, can feed sparge water always, under the few situation of composition few at the working medium dust or salt, can adopt as required and be interrupted the way that feeds sparge water, with the conserve water resource.Because spray orifice is positioned at before the movable vane, sparge water enters the little water column that spray orifice forms through jet pipe and rushes at rotor, but the movable vane on can impact rotor, thereby can not damage movable vane.Under the effect of high velocity air, the water column that spray orifice ejects forms water smoke and covers equably on the movable vane in front, salt or dust on the dissolving movable vane.Because rotor rotates, only need one or several strands of water columns just can rinse salt or dust on the moving vane well.
The utlity model has following beneficial effect:
1, uses injection equipment described in the utility model; can when moving, efficiently clean turbomachinery movable vane; thereby avoided the passage obstruction; make unit energy high-efficiency operation; even under the situation that dust content composition very big or salt is very many in working medium; can guarantee that also the unit long period normally moves, increase the cycle of shutting down maintenance.
2, injection equipment described in the utility model is simple in structure, is easy to processing and fabricating.
3, injection equipment described in the utility model can spray liquid medicine, in and dust stratification in harmful matter, remove obstinate dust stratification.
Description of drawings
Fig. 1 is that the structural drawing of the dedusting desalination injection equipment of turbine rotor vane described in the utility model reaches the scheme of installation on turbomachinery.
Among the figure, 1-spray orifice, 2-jet pipe, 3-turbine stator blade inner housing, 4-rotor, 5-one-level movable vane, 6-secondary movable vane, 7-one-level stator blade, 8-secondary stator blade.
Embodiment
In the present embodiment, the movable vane of turbomachinery is a two-stage, therefore respectively is provided with an injection equipment respectively before one-level movable vane 5 and secondary movable vane 6, as shown in Figure 1.
In the present embodiment, the structure of described injection equipment as shown in Figure 1, comprise spray orifice of offering on the turbine stator blade inner housing 31 and the jet pipe 2 that is connected with spray orifice, spray orifice 1 is positioned at before the movable vane and the spray orifice axis is 50mm apart from the distance b outside the movable vane, the Placement of spray orifice 1 and jet pipe 2 is for being threaded, the aperture of spray orifice is 6mm, and the internal diameter of jet pipe 3 is 14mm.
