Description
Technical field
The present invention relates to collapsible shield technical field, specially a kind of gas turbine inlet air system collapsible shield.
Background technology
Gas turbine is the rotary power that a kind of gas using continuous flowing is converted to mechanical work as working medium, heat energy
Machinery.Gas turbine is a kind of cooler power mechanized equipment of first and then complexity, in air and the main flow of combustion gas, only
The gas turbine cycle of compressor, combustion chamber and combustion gas turbine this three big parts composition, is commonly referred to as simple cycle.At present, combustion gas
Turbine is that, with air as working medium, its inlet air quality and degree of purity are the premises for improving unit performance and reliability.Therefore, combustion
The inlet air filter system of gas-turbine has very big economic influence to gas turbine.
It is well known that various inorganic matters and organic particle impurity are more or less included in air, it is through-flow in gas turbine
The infringement such as erosion, incrustation and corrosion will be produced in part, and this infringement can reduce the life expectancy and performance of whole equipment.
Therefore, the entrance of gas turbine inlet air system need to set a series of filter, so as to removal of impurity.But, to gas turbine
For, when inlet air filter screen is contaminated or the environment reason such as winter sleet frosting and when blocking, admission pressure loss will be notable
Increase, the loss of admission pressure, making the inlet pressure of compressor reduces, and then causes the power output in gas turbine engine hole
There is loss.Therefore, it is proposed that a kind of gas turbine inlet air system collapsible shield.
The content of the invention
It is an object of the invention to provide a kind of gas turbine inlet air system collapsible shield, by will be set at the top of bending tube
It is sealing structure, and work is respectively equipped with the left and right sides of bending tube and is distinguished, so can be not only prevented effectively from inlet air filter screen quilt
Pollution or the environment reason such as winter sleet frosting and block, can also catch more wind, extend the service life of gas turbine,
Solve the problems, such as proposed in above-mentioned background technology.
To achieve the above object, the present invention provides following technical scheme：A kind of gas turbine inlet air system collapsible shield, bag
Wind and rain cover body is included, the wind and rain cover body is made up of horizontal access, bending tube, vertical outlet and fixed mechanism, the level
The inside of porch is provided with screen pack, and the horizontal access is connected by bending tube with outlet vertically, and the bending tube includes
One horizontal extension, from the reclinate kink in one end of extension and from reclinate kink one end vertically to
The vertical extension of lower extension, is provided with fixed mechanism in the middle part of the vertical extension, the bottom of the vertical extension is provided with
Outlet vertically.
Preferably, the bird prevention net and fly net double-decker that the screen pack is made of stainless steel are formed by stacking.
Preferably, multiple unidirectional work that are respectively arranged on the left side and the right side of the horizontal extension are distinguished and sidepiece.
Preferably, several location holes are uniformly provided with the fixed mechanism.
Preferably, the vertical outlet is connected with the gas handling system of gas turbine.
Compared with prior art, beneficial effects of the present invention are as follows：
The present invention is respectively equipped with work by will be set to sealing structure at the top of bending tube on the left and right sides of bending tube
Distinguish, so can not only be prevented effectively from that inlet air filter screen is contaminated or the environment reason such as winter sleet frosting and block, can also catch
More wind are caught, the service life of gas turbine is extended.
