Rotating vane type efficient noise-reduction air filtering device for gas turbine

Abstract

The invention belongs to the technical field of gas turbines, and discloses a rotating vane type efficient noise-reduction air filtering device for a gas turbine. The rotating vane type efficient noise-reduction air filtering device comprises a coarse-efficiency filtering unit and a self-cleaning filter. The coarse-efficiency filtering unit and the self-cleaning filter are arranged in a gas inlet channel of the gas turbine in a spaced mode. The self-cleaning filter comprises a plurality of filter barrels arranged in the gas inlet channel vertically, and the filter barrels are provided with reverse blowing pipes communicated with an external compressed air source through a pipeline. Each filter barrel comprises a filter barrel framework which is composed of an outer metal mesh layer and an inner metal mesh layer, and each outer metal mesh layer and the corresponding inner metal mesh layer form the corresponding cylindrical filter barrel framework with three faces surrounded; a filter layer is arranged between each outer metal mesh layer and the corresponding inner metal mesh layer, and flow guiding bars are obliquely arranged on the inner metal mesh layers; a noise reduction module is arranged at the rear end of the pipeline.

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-reducing 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 pus...
