Description

Technical Field

[0001] This utility model relates to a flow guiding structure, and more particularly to a flow guiding structure applied to a gas turbine exhaust system. Background Technology

[0002] The exhaust system of a gas turbine is one of the important auxiliary systems for the operation of a gas turbine, playing a crucial role in its efficiency and normal operation. The flow guide structure, as the core component of the exhaust system, directly affects the smoothness of the exhaust gas flow and needs to absorb the thermal expansion generated by the exhaust gas. Traditional gas turbine exhaust system flow guide structures are welded to the exhaust system, making them impossible to disassemble and replace. Relying on the metal material itself to absorb thermal expansion easily leads to significant plastic deformation, which cannot ensure the stability of the gas turbine exhaust system and affects the smoothness of the exhaust gas flow. Therefore, designing a flow guide structure that can absorb thermal expansion through a reasonable structure, is easy to disassemble, and ensures the smoothness of the gas turbine exhaust gas flow is of great significance for the stability of the gas turbine exhaust system operation and the flexibility of its installation. Summary of the Invention

[0003] The purpose of this invention is to provide a flow guide structure for use in gas turbine exhaust systems. This flow guide structure can be easily disassembled and replaced, can absorb a large amount of thermal expansion, ensure the smooth flow of gas discharged from the gas turbine, and ensure the stability of the gas turbine exhaust system operation and the flexibility of installation.

[0004] The above objective is achieved through the following technical solution: a flow guiding structure applied to a gas turbine exhaust system, including a flow guiding support 1, a flow guiding support 2, a flow guiding vane 1, and a flow guiding vane 2.

[0005] The guide support has a connection hole at the bottom for connecting and fixing to the gas turbine exhaust system, and an arc-shaped cut in the middle.

[0006] The bottom of the flow guide support is provided with a connection hole for connecting and fixing to the gas turbine exhaust system, and there is an arc-shaped cut in the middle.

[0007] The flow guide plate needs to be inserted centered into the arc-shaped cut of the flow guide support and welded to the flow guide support.

[0008] The first guide vane needs to be inserted into the arc-shaped cut of the second guide support, and does not need to be fixed.

[0009] The second guide vane needs to be inserted centered into the arc-shaped cut of the first guide support and welded to it.

[0010] The second guide vane needs to be inserted into the arc-shaped cut of the second guide support, and does not need to be fixed. Beneficial effects

[0011] The flow guiding structure of this utility model is easy to disassemble and replace, can absorb a large amount of thermal expansion, ensures the smooth flow of gas discharged from the gas turbine, and ensures the stability of the gas turbine exhaust system and the flexibility of installation.

[0012] The flow guiding structure of this utility model has a load-bearing structure made of carbon structural steel, which is connected by welding and bolts to ensure structural stability and safe operation. Attached Figure Description
