Abstract

The invention provides a gas turbine which comprises a filter provided with an inlet and an outlet and used for filtering gas, a gas compressor used for compressing the gas and communicated with the outlet, a combustor positioned at the downstream portion of the gas compressor in the flowing direction of the gas and communicated with the gas compressor so that the gas can be combusted in the combustor, an exhaust pipeline provided with an exhaust port and a discharge port, and a throttling part; the exhaust port is communicated with the gas compressor; the discharge port is located at the upstream portion of the inlet in the flowing direction of the gas; the exhaust pipeline is used for extracting the compressed gas through the exhaust port so that the gas can be input into the filter through the discharge port; and the throttling part is arranged on the exhaust pipeline and used for limiting flow of the gas flowing into the filter from the gas compressor. The embodiment of the invention provides the gas turbine which is simple in structure and capable of solving the problems that the service life is shortened due to the fact that a filter element is affected with damp, and safe operation is affected by frosting and freezing.

Description

technical field [0001] The present application relates to a gas turbine. Background technique [0002] A gas turbine is a rotary power machine that uses a continuous flow of gas as a working medium to convert heat energy into mechanical work. For gas turbines, when the inlet air filter element is polluted by rainy season moisture, smog, or frost, or even freezes, it will cause blockage, which will cause a significant increase in intake pressure loss and reduce the inlet pressure of the compressor. When the maximum pressure of the gas engine cycle is kept constant, the specific power of the compressor must be increased. At this time, more turbine output will be consumed to drive the compressor, resulting in a decrease in the power and efficiency of the gas turbine; in severe cases, it may cause the gas turbine to shut down incorrectly or the filter element Suction breaks, enters the unit, and breaks the high-speed rotating gas turbine blades. [0003] In the prior art, the ...
