Problems solved by technology
[0006] The air intake system of large gas turbines is very large, and the rectification section of the air intake pipe is also very large in volume and weight, which is extremely inconvenient to install, and how to ensure the firmness after installation is also a problem that needs to be solved. Technical rectification sections, including the above Chinese patents, have not solved the above problems well

Embodiment Construction
[0046] The present invention will be further described in detail below in conjunction with the accompanying drawings and examples. The following examples are explanations of the present invention and the present invention is not limited to the following examples.
[0047] see Figure 1 to Figure 15 , the embodiment of the present invention includes a rectifying section of an air intake duct of a gas turbine intake system, which includes a pipe body 1 , an insulating structure 2 and a rectifying structure 3 .
[0048] The pipe body 1 is open in the middle and is rectangular, and the cross-sectional area of the internal flow channel reaches 5790mmx5790mm, which meets the air intake requirements of large gas turbines. The pipe body 1 includes an upper top panel assembly 4 , a lower bottom panel assembly 5 , and two side panel assemblies 6 which are fixed together. The direction of the pipe body 1, that is, the east-west direction is the airflow direction of the rectification sec...

The invention relates to an air inlet rectification device of a large gas turbine. The air inlet rectification device is characterized in that an upper-side top plate assembly is arranged at the top of a pipe body, a lower-side bottom plate assembly is arranged at the bottom of the pipe body, and two-side panel assemblies are arranged on the left and right sides of the pipe body; the periphery of a rectification plate is fixed with a connector, the rectification plate comprises a plurality of steel supporting plates, and the steel supporting plates are crossed with one another to form the net-shaped rectification plate; a framework comprises multiple pieces of profile steel, the multiple pieces of profile steel are crossed with one another to form the net-shaped framework, and a grid is used for fixing a rectification filter net; insulated materials are fixedly arranged in the grids of the framework, insulated material cover plates are fixed with the profile steel, and a grid is used for fixing an insulated material and an insulate material cover plate; insulated structures are fixedly arranged on the upper-side top plate assembly, the lower-side top plate assembly and the two-side panel assemblies. The air inlet rectification device is reasonable in structural design, convenient to mount and good in firmness.
Description
technical field [0001] The invention relates to an air intake straightening device for a large gas turbine. Background technique [0002] A gas turbine is a rotary power machine that uses continuously flowing gas as a working medium to convert heat energy into mechanical work. It is an advanced and complex complete set of power machinery equipment and a typical high-tech intensive product. As a high-tech carrier, the gas turbine represents a comprehensive level of development in multiple theoretical disciplines and multiple engineering fields. The development of a gas turbine industry that integrates new technologies, new materials, and new processes is one of the important symbols of the country's high-tech level and scientific and technological strength, and has a very prominent strategic position. [0003] Due to many reasons, there is still a big gap between my country's gas turbine and the international advanced level, and a real industry has not yet formed. The state...
