[0001] The present invention relates to a gas turbine, in particular to a noise reduction device for a gas turbine, belonging to the technical field of gas turbines. Background Art

[0002] A marine gas turbine is an important power device on modern ships. It first compresses air through a compressor and then introduces it into a combustion chamber. Fuel burns in the combustion chamber to generate high-temperature gas, which then enters a turbine and impacts the blades on the turbine, causing the turbine to rotate at high speed and drive the propeller to work.

[0003] A gas turbine does not require a boiler, is light in weight, small in size, and has a large power, and can be used as the main engine of a large ship.

[0004] The existing gas turbines will generate relatively large vibrations during use, and vibrations are inevitable. However, the vibration energy generated can be utilized. In the existing technology, only fixing and vibration reduction designs are carried out, but for gas turbines used for a long time, vibration problems will inevitably occur. In addition, the existing gas turbines do not have good temperature reduction and noise reduction functions. Although air cooling is achieved, the energy cannot be fully reused, resulting in waste of energy. Therefore, a noise reduction device and method for a gas turbine are designed to solve the above problems. Summary of the Invention

By vibrating and compressing the air in the buffer airbag, the second one-way valve is opened, and the air enters the second connecting pipe through the second one-way valve, and then drives the fan blades to rotate. By rotating the fan blades, the generator is adjusted to generate electricity and store electrical energy. The air enters the hollow ring-shaped cover through the first connecting pipe, enters the upper air guide pipe through the hollow ring-shaped cover and then is introduced into the heat exchange cover and discharged from the liquid outlet pipe.
