Three-grade efficient noise-elimination air filtering system used for combustion gas turbine

Abstract

The invention belongs to the technical field of combustion gas turbines, and discloses a three-grade efficient noise-elimination air filtering system used for a combustion gas turbine. The three-grade efficient noise-elimination air filtering system comprises a filtering room. A low efficiency filter device, a medium efficiency filter and a high efficiency filter are arranged in the filtering room. An overhauling channel is arranged between the low efficiency filter device and the medium efficiency filter. An overhauling channel is arranged between the medium efficiency filter and the high efficiency filter. The low efficiency filter device comprises a connecting rod and a plurality of vertically-arranged low efficiency filters. The upper ends of the low efficiency filters are hinged to the interior of the filtering room. The other ends of the low efficiency filters are hinged to the same connecting rod. A stretchable air cylinder or a stretchable hydraulic cylinder is hinged to the bottom face of the low efficiency filter located at the lowermost end. The other end of the air cylinder or the hydraulic cylinder is hinged to the interior of the filtering room. A noise eliminating module is further arranged in the filtering room.

Description

technical field [0001] The invention belongs to the technical field of gas turbines, and in particular relates to a three-stage high-efficiency noise reduction air filter system for gas turbines, which is used for purifying and filtering the intake air of the gas turbines. The invention can also be used for air purification 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-pressur...
