Inter-cooled header type gas turbine unit with split compressors

An inter-cooled header type gas turbine unit with split compressors is characterized by comprising at least two groups of low-pressure compressors and high-pressure compressors which are coaxial, a combustion chamber, a turbine, an inter-cooling header, an outlet header and an absorption refrigerator, wherein an input shaft of each low-pressure compressor is connected with a compressor motor through a coupling; an air outlet of each low-pressure compressor is connected with an air inlet of the inter-cooling header, and an air outlet of the inter-cooling header is connected with air inlets of the high-pressure compressors respectively; and a smoke outlet of the turbine is connected with a smoke inlet of the absorption refrigerator provided with a cooling medium inlet and a cooling medium outlet, the inter-cooling header is provided with a cooling medium inlet and a cooling medium outlet, and the cooling medium outlet of the absorption refrigerator is connected with the cooling medium inlet of the inter-cooling header. The coaxial high-pressure compressors and the low-pressure compressors can be started and stopped independently, the utilization effect of cooling medium closed cycle waste heat is good, and use of economical and diversified distributed energy sources is achieved effectively.
