Description
Technical field
The invention belongs to gas turbine technology field is and in particular to a kind of highly-efficient barrel-type air filtration for gas turbine
Device device, for carrying out filtration, purification to the air introducing gas turbine, the present invention can be also used for the air of other field simultaneously
Filtration, purification.
Background technology
Gas turbine is the rotary power that a kind of gas using continuous flowing is converted to heat energy as working medium mechanical work
Machinery.In the main flow of air and combustion gas, mainly combustion gas is formed by this three big part of compressor, combustor and combustion gas turbine
Turbine circulates.
Compressor sucks air from ambient atmosphere environment, and compresses step by step through axial-flow compressor and be allowed to be pressurized, simultaneously
Air humidity also accordingly improves；The combustion gas that compressed air is pressed to combustor with the fuel mixture manufacturing High Temperature High Pressure spraying into；
Then enter back into expansion work in turbine, promote turbine drive compressor together with outer load rotor high-speed rotation it is achieved that
The chemical energy of gas and liquid fuel is converted into mechanical energy, and exports electric work.
The inlet air flow of gas turbine blower is that the combustion air of gas turbine must be carried out before being introduced into compressor

The tubular structure constituting, described interior metal net layer is the tubular structure being made up of corrugated metal net layer, described outer wire netting
The crest of layer is mutually corresponding with the crest of interior metal net layer and trough respectively with trough.
The outer wall of described breather is provided with a point QI KOU.
On the outer wall being arranged on breather at described point of QI KOU interval.
Described cloth QI KOU becomes round table-like with the section of point QI KOU, and the described cloth QI KOU end face larger with point QI KOU bore
Towards filter paper.
The cloth QI KOU of described air-spreading disk bottom tilt towards filter paper.
Compared with prior art, the method have the advantages that
The cylindrical air filter for gas turbine of the present invention, including cartridge filter skeleton, cartridge filter skeleton is by outer gold
Belong to stratum reticulare and interior metal net layer composition, outer metal net layer and interior metal net layer composition cartridge filter skeleton, outer metal net layer and Endothelium corneum
Belong to and be provided with filter paper between stratum reticulare, the two ends of cartridge filter skeleton are connected to end cover, and an end cover is connected with and mistake
The breather of connection inside filter cylinder frame, the bottom of breather is connected with air-spreading disk, and the side of air-spreading disk and bottom surface all offer
Cloth QI KOU；Outer metal net layer is the tubular structure being made up of corrugated metal net layer, and interior metal net layer is by corrugated gold
Belong to the tubular structure that stratum reticulare is constituted, the crest of outer metal net layer and trough are mutually right with the crest of interior metal net layer and trough respectively
Should.By changing outer metal net layer and inner layer metal net-layer structure, both increased the area of the filter paper of placement, and improved and filter effect
Rate；It is also prevented from the change of flow direction causing because of the folding of filter paper simultaneously, so that air flows steadily on filter paper,
