Abstract

The invention belongs to the technical field of air filtering of gas turbines and discloses a silent air filtering device with an efficient cyclic utilization function. The silent air filtering device comprises a top drive roller, a bottom drive roller and driven rollers. The driven rollers are arranged in a filtering chamber in a left-right alternation manner. The top drive roller, the driven rollers and the bottom drive roller are wrapped with filtering layers. The side face of the filtering chamber is provided with an air inlet. The air inlet right faces the filtering layers wrapping the top drive roller, the driven rollers and the bottom drive roller. A blowing system is arranged above the filtering layer between the driven roller at the lowest end of the filtering chamber and the bottom drive roller. A muffling module is assembled at the air inlet and comprises two first muffling modules and at least one second muffling module. The second muffling modules are arranged between every two first muffling modules in a spaced manner. Each first muffling module comprises two first lead fiber acoustic panels, wherein a first glass wool layer is arranged between the two first lead fiber acoustic panels.

Description

technical field [0001] The invention belongs to the technical field of gas turbine air filtration, and in particular relates to a high-efficiency recycling sound-absorbing air filter device, which is used to filter the air entering the gas turbine. Meanwhile, the invention can also be used for air 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...
