Rotary blade type air filter with high-efficiency silencing effect

Abstract

The invention belongs to the technical field of gas turbines, and discloses a rotary blade type air filter with a high-efficiency silencing effect. The air filter comprises a course-effect filter and a self-cleaning filter, wherein the course-effect filter and the self-cleaning filter are arranged at an interval in an air inlet channel of a gas turbine; the self-cleaning filter comprises a plurality of filtering cylinders arranged in the air inlet channel up and down; each filtering cylinder is provided with a reverse blowing pipe communicated with an external compressed air source through a pipeline; each reverse blowing pipe is arranged in the air inlet channel at the rear end of the corresponding filtering cylinder; each filtering cylinder comprises a filtering cylinder framework; each filtering cylinder framework consists of an outer metal mesh layer and an inner metal mesh layer; each cylindrical filtering cylinder framework encircled by three sides is formed by one outer metal mesh layer and the corresponding inner metal mesh layer; one filtering layer is arranged between each outer metal mesh layer and the corresponding inner metal mesh layer; spiral flow guiding strips are obliquely arranged on each inner metal mesh layer; silencing modules are arranged between the course-effect filter and the self-cleaning filter.

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-eliminating air filter device for filtering air entering a gas turbine. 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 ...
