Abstract

The invention belongs to the technical field of air filtering for gas turbines, and discloses a three-level efficient noise-reduction air filtering system. The system comprises a filtering chamber, and a coarse-efficiency filter, a medium-efficiency filter and an efficient filter are arranged in the filtering chamber. An overhaul channel is formed between the coarse-efficiency filter and the medium-efficiency filter, and an overhaul channel is formed between the medium-efficiency filter and the efficient filter. The medium-efficiency filter comprises a top driving drum, a bottom driving drum and driven drums, wherein the top driving drum and the bottom driving drum are mounted in the filtering chamber, and the driven drums are mounted between the top driving drum and the bottom driving drum and mounted in the filtering chamber in a left-right alternating mode. The top driving drum, the driven drums and the bottom driving drum are wrapped with filtering layers, and a spraying and blowing system is arranged above the filtering layers between the driven drum located at the lowermost end of the filtering chamber and the bottom driving drum. A noise reduction module is arranged between the medium-efficiency filter and the efficient filter.

Description

technical field [0001] The invention belongs to the technical field of air filtration of gas turbines, and in particular relates to a three-stage high-efficiency noise reduction air filtration system, which is used for filtering the air entering a gas turbine, and can also be used for air filtration in other fields. Background technique [0002] A gas turbine is a rotary power machine that converts thermal energy into mechanical work using a continuous flow of gas as a working medium. In the main process of air and gas, the gas turbine cycle is mainly composed of three components: compressor, combustion chamber and gas turbine. [0003] The compressor inhales air from the external atmospheric environment, and compresses it step by step through the axial flow compressor to pressurize it, and the air humidity also increases accordingly; the compressed air is pressed to the combustion chamber and mixed with the injected fuel to produce high temperature and high pressure gas. ;...
