Gas inlet system of gas turbine

The invention discloses a gas inlet system of a gas turbine. The system comprises a gas inlet module, the gas inlet module comprises a rain and snow prevention section, a dehydration section, a gas purification section, a noise elimination section and a hardening and tempering section which are sequentially connected in series, one end of the gas inlet module is provided with a gas inlet, and the other end of the gas inlet module is provided with a gas outlet connected with an inlet of a gas turbine aerostatic press. The rain and snow prevention section, the dehydration section, the gas purification section, the noise elimination section and the hardening and tempering section are fixedly mounted on a steel frame. The system can be combined and matched according to different gas turbine main engine requirements and on-site conditions and then installed at an inlet of a gas turbine compressor, it is ensured that the gas turbine obtains an air working medium meeting the requirements, safe operation of the gas t
