Description
Technical field
The present invention relates to a kind of inlet ducts of LNG gas turbine steam combined cycle power generating, belong to generating equipment technology
Field.
Background technique
The actuation of the engine of the generator of LNG gas turbine steam combined cycle power generating need to will be extraneous by air cleaner
Air import, and the current air inlet pipe of generator be all air inlet pipe is opening down to be arranged, come avoid foreign matter fall into
Intratracheally, but this structure not can avoid foreign matter still and enter in dynamo engine, if things go on like this, can make dynamo engine
Damage.In order to solve the above difficulties, need to develop a kind of a LNG gas turbine for being avoided that foreign matter and entering dynamo engine
The inlet duct of steam combined cycle power generating.
Summary of the invention
The object of the present invention is to provide a kind of inlet ducts of LNG gas turbine steam combined cycle power generating.
The problem to be solved in the present invention is that the generator air inlet pipe of the prior art is easy that foreign matter is made to enter dynamo engine
In problem.
To achieve the purpose of the present invention, the technical solution adopted by the present invention is that:
A kind of inlet duct of LNG gas turbine steam combined cycle power generating, including air inlet pipe, Collapsible cover, copper pipe, locking
Frame, non-woven fabrics, screw, outer Turbogrid plates, inside grid and steel bushing, the air inlet pipe right end install Collapsible cover, Collapsible cover right end peace
Copper pipe is filled, copper pipe is externally provided with external screw thread, and internal screw thread, steel bushing and copper pipe are equipped in steel bushing and is mutually coincide by screw thread, on the right side of steel bushing
Equipped with outer Turbogrid plates, non-woven fabrics is laid on the left of outer Turbogrid plates, non-woven fabrics is located in steel bushing, and inside grid, interior grid are equipped in steel bushing
Panel is covered on the left of non-woven fabrics, inside grid two sides each installation locking frame up and down, mounting screw on locking rack, and screw is by locking rack
It is fixed on steel bushing inner sidewall and inside grid.
The non-woven fabrics has double-layer structure.
The invention has the advantages that outside air is avoided that foreign matter by the filtering of outer Turbogrid plates, non-woven fabrics and inside grid
It is fallen in engine from air inlet pipe；Steel bushing is rotated, unscrews screw, inside grid can be removed, so that it may replace non-woven fabrics；Collapsible cover
With stretch function, it can shorten or expand the distance that outside air enters air inlet pipe.
Detailed description of the invention
Fig. 1 is a kind of inlet duct Facad structure figure of LNG gas turbine steam combined cycle power generating of the present invention；
In figure: 1, air inlet pipe 2, Collapsible cover 3, copper pipe 4, locking rack 5, non-woven fabrics 6, screw 7, outer Turbogrid plates 8,
Inside grid 9, steel bushing.
Specific embodiment
The present invention is further illustrated with reference to the accompanying drawings and embodiments.
A kind of inlet duct of LNG gas turbine steam combined cycle power generating of the present invention, including air inlet pipe 1, Collapsible cover 2,
Copper pipe 3, locking rack 4, non-woven fabrics 5, screw 6, outer Turbogrid plates 7, inside grid 8 and steel bushing 9,1 right end of the air inlet pipe installation folding
Folded cover 2, Collapsible cover 2 have stretch function, can shorten or expand the distance that outside air enters air inlet pipe 1, and Collapsible cover 2 is right
End installation copper pipe, copper pipe are externally provided with external screw thread, and internal screw thread, steel bushing 9 and copper pipe are equipped in steel bushing 9 and is mutually coincide by screw thread, steel
9 right side of set is equipped with outer Turbogrid plates, is laid with non-woven fabrics 5 on the left of outer Turbogrid plates, and non-woven fabrics 5 is located in steel bushing 9, and non-woven fabrics 5 has two
Layer structure, steel bushing 9 is interior to be equipped with inside grid 8, and inside grid 8 covers in 5 left side of non-woven fabrics, and outside air passes through outer Turbogrid plates 7, nothing
The filtering of woven fabric 5 and inside grid 8 is avoided that foreign matter is fallen in engine from air inlet pipe 1；Respectively pacify about 8 two sides of inside grid
Locking rack 4, mounting screw 6 on locking rack 4 are filled, locking rack 4 is fixed on 9 inner sidewall of steel bushing and inside grid 8 by screw 6, is turned
Dynamic steel bushing 9, unscrews screw 6, can remove inside grid 8, so that it may replace non-woven fabrics 5.
Application method of the present invention: outside air is avoided that by the filtering of outer Turbogrid plates 7, non-woven fabrics 5 and inside grid 8
Foreign matter is fallen in engine from air inlet pipe 1；Steel bushing 9 is rotated, unscrews screw 6, inside grid 8 can be removed, so that it may replace nonwoven
Cloth 5；Collapsible cover 2 has stretch function, can shorten or expand the distance that outside air enters air inlet pipe 1.
