Abstract

The invention belongs to the technical field of a gas turbine, and discloses a high efficiency and energy saving blowback device used for a gas turbine air inlet system which is used for solving the problems of poor blowing effect, compressed air source and energy waste, and reduction of the working efficiency of the whole air filtration system of a blowback device in the prior art. The high efficiency and energy saving blowback device includes a blowback pipe which is communicated with a compressed air source by a pipe, also includes a conical guiding device, the center line of the guiding device and the center line of the blowback pipe are in the same straight line, the center line of the guiding device and the center line of an air filter filtering cartridge are in the same straight line, the top of the guiding device and the end surface of the blowback pipe are flushed, or the top of the guiding device stretches into the blowback pipe, and the bottom surface of the guiding device just faces toward the center of the air filter filtering cartridge.

Description

technical field [0001] The invention belongs to the technical field of gas turbines, and in particular relates to a high-efficiency energy-saving reverse blowing device used in gas turbine intake systems. 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 ...
