Rotating vane type efficient noise elimination air filtration device for gas turbine

Abstract

The invention belongs to the technical field of gas turbines, and discloses a rotating vane type efficient noise elimination air filtration device for a gas turbine. The rotating vane type efficient noise elimination air filtration device comprises a coarse filtration device and a self-cleaning filter. The coarse filtration device and the self-cleaning filter are arranged in an air intake channel of the gas turbine in a spaced manner. The self-cleaning filter comprises a plurality of filter drums arranged in the air intake channel in an up-and-down manner. The filter drums are provided with reverse blowing pipes which are communicated with an external compressed air source through a pipeline. Each filter drum comprises a filter drum framework. Each filter drum framework is composed of an external metal net layer and an internal metal net layer which form the right-angle-U-shaped cylindrical filter drum framework. Filter layers are arranged between the external metal net layers and the internal metal net layers. Spiral flow guide strips are arranged on the internal metal net layers in an inclined manner. A noise elimination module is arranged at the position, behind the pipeline, in the air intake channel.

Description

technical field [0001] The invention belongs to the technical field of gas turbines, and in particular relates to a rotary vane type high-efficiency noise reduction air filter device for gas turbines. The invention can also be used for air purification and filtration in other fields. Background technique [0002] A gas turbine is a rotary power machine that converts heat energy into mechanical work using continuously flowing gas as a working medium. In the main process of air and gas, the gas turbine cycle is mainly composed of three major components: the compressor, the combustion chamber and the gas turbine. [0003] The compressor inhales air from the external atmosphere, and pressurizes it step by step through the axial flow compressor, and the air humidity is also increased accordingly; the compressed air is sent to the combustion chamber to mix with the injected fuel to produce high-temperature and high-pressure gas Then enter the turbine to expand and do work, and pu...
