Description

Technical Field

[0001] The present invention relates to the technical field of gas turbine cleaning, and in particular to a gas turbine intelligent cleaning robot. Background Art

[0002] A gas turbine draws in air through a compressor, pressurizes it, and feeds it into a combustion chamber. A fuel pump injects fuel through a nozzle into the combustion chamber, where it mixes with the air. The resulting high-temperature, high-pressure combustion gas then enters the turbine, where it expands and produces work. The exhaust gas is then released back into the atmosphere, releasing heat. Part of this expansion work is transmitted via a drive shaft to the compressor and other auxiliary machinery, while the remainder is output to generate electricity or generate power.

[0003] In some gas turbine inlet systems, the filter chamber is a critical component, located on the path before air enters the compressor. However, inclement weather or after prolonged use inevitably lead to the accumulation of dust and impurities in the filter assembly at the inlet of the filter chamber. These accumulated pollutants not only reduce the filter efficiency but may also damage the filter assembly's physical structure, thus affecting the performance and life of the entire gas turbine system.

[0004] Traditionally, cleaning these filter components has relied on manual labor, which is not only time-consuming and labor-intensive, but in some cases, can be extremely difficult or even impossible due to the specific location or space constraints of the filter chamber. Furthermore, manual cleaning can pose safety risks, such as working at height and exposure to hazardous substances.

[0005] In order to maintain the filtering effect and extend the service life of the filter component, we propose a gas turbine intelligent cleaning robot. Summary of the Invention
