Abstract

The invention belongs to the technical field of gas turbines and discloses a three-stage efficient silencing air filtering unit for a gas turbine, which is used for solving the problem of poor damping and sound insulating effect in a conventional device. The three-stage efficient silencing air filtering unit for the gas turbine comprises a filtering room, wherein a low efficient filter, a medium efficiency filter and a high efficiency filter are arranged inside the filtering room in sequence, the medium efficiency filter comprises a plurality of filter drums arranged up and down, the filter drums are equipped with back flushing pipes communicated through a compressed air source outside a pipeline, and the back flushing pipes are arranged at the rear ends of the filter drums; each filter drum comprises a filter drum framework, the filter drum framework comprises an outer metal net layer and an inner metal net layer, the outer metal net layer and the inner metal net layer form a three-side surrounded cylindrical filter drum framework, a filtering layer is arranged between the outer metal net layer and the inner metal net layer, a spiral flow guide strip is arranged on the inner metal net layer, and the spiral flow guide strip is obliquely arranged on the inner metal net layer; and a silencing module is arranged between the low efficient filter and the medium efficiency filter.

Description

technical field [0001] The invention belongs to the technical field of gas turbines, and in particular relates to a three-stage high-efficiency silencing air filter device for gas turbines, which is used for purifying and filtering the intake air of the gas turbines. The invention can also be used for air purification 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 ...
