The invention relates to a combustion turbine generator device using yellow phosphoric tail gas as fuel. The invention comprises a yellow phosphorus furnace, a purification system, a yellow phosphoric tail gas pressurizing and filtering device, a generator set assembly and load. The key points of the invention lies in that: the yellow phosphoric tail gas pressurizing and filtering device is assembled by connecting a pulse bag type filter, a carbon monoxide compressor and a gas purification device; the gas purification device consists of a sediment chamber and hollow fiber filter material; thegenerator set assembly is assembled by connecting a fuel regulating and executing mechanism, a gas valve, a fuel circular general pipe, a fuel nozzle and a combustion turbine. The structure of the invention is simple and practical. Using yellow phosphoric tail gas as fuel for electricity generating of the combustion turbine resolves the problems of yellow phosphoric tail gas diffusion and waste, meanwhile lowers one sixth energy consumption in yellow phosphorus production, reduces the discharge of yellow phosphorus into the air, utilizes precious resources, changes and protects the environment and creates benefits for enterprises.
