Efficient noise elimination air intake device for gas turbine

Abstract

The invention belongs to the technical field of gas turbines and discloses an efficient noise elimination air intake device for a gas turbine. The efficient noise elimination air intake device comprises an air intake cavity, a filtering cylinder, a blowback cavity and a blowback system. The blowback cavity is located in the upper portion of the air intake cavity. One end of the filtering cylinder is located in the air intake cavity, and the other end of the filtering cylinder is located in the blowback cavity. The blowback system comprises a blowback pipe connected with a compression air source through a pipe. The blowback system further comprises a conical guiding device. The center line of the guiding device and the center line of the blowback pipe are located on the same straight line. The center line of the guiding device and the center line of the filtering cylinder are located on the same straight line. The top end of the guiding device is flush with the end face of the blowback pipe or stretches into the blowback pipe. The bottom face of the guiding device right faces the center of the filtering cylinder. A muffling module is assembled in the air intake cavity.

Description

technical field [0001] The invention belongs to the technical field of gas turbines, and in particular relates to a high-efficiency noise reduction air intake device for gas turbines. 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 expand and do work, and push the turbine to drive the compressor and the external load rotor to rotate at high speed together, ...
