Ventilation mechanism for gas turbine air inlet system

Abstract

The invention relates to the technical field of related composition mechanisms of gas turbine air inlet systems, and discloses a ventilation mechanism for a gas turbine air inlet system. The ventilation mechanism comprises a machine frame, wherein a mounting seat is mounted at a ventilation opening of the machine frame through a bolt, a vertical channel is arranged on the mounting seat, the otherend of the vertical channel is connected with a bent channel, the other end of the bent channel is connected with a transition channel, a ventilation filter frame is installed at the port, away from the bent channel, of the transition channel, a sealing opening and closing door used for overhauling is arranged on the front face of the ventilation filter frame, the end, away from the bent channel,of the vertical channel is sleeved with a flange connecting base, and two sealing bearings and two sealing rings are clamped between the inner side wall of the flange connecting base and the verticalchannel. The ventilation mechanism for the gas turbine air inlet system is different from a traditional ventilation mechanism noise reduction mechanism, the flow guide resistance and the circulation length of the ventilation filter frame are increased when external airflow is guided in, airflow noise generated by flow path reduction is reduced, and noise reduction treatment can be conducted on equipment from the noise generation position.

Description

technical field [0001] The invention relates to the technical field of components related to gas turbine intake systems, in particular to a ventilation mechanism for gas turbine intake systems. Background technique [0002] The gas turbine is an internal combustion power machine that uses continuous flowing gas as the working medium to drive the impeller to rotate at high speed, and converts the energy of the fuel into useful work. It is a rotating impeller heat engine. Filtration of tiny particulate impurities to ensure full combustion of fuel inside the gas turbine generally requires the use of an air intake system. A series of filter devices in the air intake system are used to remove droplets, dust, pollen and suspended particles in the air, and provide gas turbines with The clean air that meets the requirements provides effective and reliable protection for the compressor blades during normal operation. [0003] When the gas turbine is installed and used in the intake ...
