The invention discloses an ammonia water turbine sealing system taking nitrogen as a seal medium. The system is characterized by comprising a shaft seal, a buffer tank and a nitrogen tank; the shaft seal is arranged at one end, extending out of a cylinder, of the spindle; the outer end of the shaft seal is connected with the buffer tank by a first pipeline provided with a first control valve; the buffer tank is provided with a pressure sensor and is connected with the nitrogen tank by a second pipeline; the second pipeline is provided with a second control valve. The ammonia water turbine sealing system taking nitrogen as the seal medium effectively solves the problem that an ammonia water working medium leaks to the outside, the turbine efficiency is improved, the working medium loss is reduced, and the safety and stability of the operation of an ammonia water power generation system are ensured.
Description
technical field [0001] The invention belongs to the technical field of ammonia water turbine power generation, and in particular relates to an ammonia water turbine sealing system using nitrogen as a sealing medium. [0002] Background technique [0003] With the gradual deepening of energy saving and emission reduction, higher temperature heat sources have been widely used. However, medium and low temperature heat sources are still less used in industrial production. In the utilization of medium and low temperature heat sources, conventional power generation with water as the medium is difficult to show advantages, while power generation with ammonia water as the working medium is gradually favored by users. In a power generation system using ammonia water as the working medium, during the operation of the turbine, since the working pressure is greater than the external pressure, the ammonia water working medium will leak out through the gap between the cylinder and the...
