Embodiment Construction
[0015] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0016] The gas turbine intake system is an important part of the gas turbine, mainly composed of filters, expansion joints, mufflers, bends, transition sections, extension sections, compressors and other equipment components.
[0017] The gas turbine intake system bend referred to in the present invention is located between the filter sound-absorbing component and the compressor, and is composed of an intake volute and a shrinking nozzle. It is used to make the main air flow transition from the radial direction of the unit to the axial direction before entering the compressor, so the gas turbine intake air passage has a non-axisymmetric structural feature of radial intake and axial exhaust, and the air flows through the intake air passage In addition to the flow loss, non-axisymmetric flow will be generated at the inlet cross-section (that is, the compr...

The invention relates to an air inlet bending head reinforced shock absorption structure of an internal combustion turbine, which comprises an internal combustion turbine air inlet system bending passage, an internal combustion turbine air inlet system bending head, a connecting plate and an internal combustion turbine air inlet system vertical section. The invention is characterized in that a reinforcing structure is arranged outside an internal combustion turbine air inlet system bending passage case, and a reinforced structure and a shock absorption structure are arranged outside the internal combustion turbine air inlet system bending head case. The invention realizes the integrated design of the air inlet bending reinforced shock absorption structure of the internal combustion turbine, adopts the combination forms of the reinforcing structures of I-shaped steel, H-shaped steel, channel steel and the like, and improves the damage-resistance intensity of the internal combustion turbine air inlet bending passage, and adopts the shock absorption structure for realizing the unloading of the bending part on the vibration effect. The structural design is novel and reasonable, and the invention has wide practical application value.
Description
technical field [0001] The patent of the present invention relates to a reinforced and shock-absorbing structure, especially a reinforced and shock-absorbing structure for gas turbine intake systems. Background technique [0002] Gas turbine power generation has the advantages of high efficiency, cleanliness, and less pollution. Gas turbine units can quickly start, respond, and load loads in emergencies. They are suitable as emergency backup and peak load power sources in the grid, and can better ensure the safety and operation of the grid. . [0003] The gas turbine intake system is an important auxiliary system of the gas turbine. It has the characteristics of large volume and complex structure. It is relatively difficult to analyze its structure and take technical measures to reinforce and reduce structural vibration. On the other hand, traditional research mainly focuses on the relationship between the gas turbine body, combustion chamber, blade form, unit operation mod...
