Abstract

The invention belongs to the technical field of gas turbine engine air filtration, and discloses a high-efficiency sound-muffling three-level air filtration system. The high-efficiency sound-muffling three-level air filtration system comprises a filtration room, wherein a low-efficiency filter, a middle-efficiency filter and a high-efficiency filter are arranged in the filtration room; the middle-efficiency filter comprises a top driving rotary drum, a bottom driving rotary drum and driven rotary drums; the driven rotary drums are arranged in the filtration room in a left and right alternating manner; the top driving rotary drum, the driven rotary drums and the bottom driving rotary drum are wrapped with filtration layers, and an injection system is arranged above the filtration layer between the driven rotary drum and the bottom driving rotary drum; the injection system comprises conical flow guiding devices and reverse blowing pipes connected with a compressed air source; the center lines of the flow guiding devices and the center lines of the reverse blowing pipes are on the same straight line, and the bottom surfaces of the flow guiding devices directly face the filtration layer between the driven rotary drum at the bottom of the filtration room and the bottom driven rotary drum; and a sound-muffling module is arranged between the low-efficiency filter and the middle-efficiency filter.

Description

technical field [0001] The invention belongs to the technical field of gas turbine air filtration, and in particular relates to a high-efficiency noise reduction three-stage air filtration system, which is used for filtering the air entering the 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 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 turbin...
