Abstract

The invention discloses an ammonia water turbine sealing system taking water vapor as a seal medium. The system comprises a shaft seal and a water storage tank; the shaft seal is arranged at one end, extending out of a cylinder, of a spindle; the water storage tank comprises a gas phase area at the upper part and a liquid phase area at the lower part; the shaft seal is connected with the gas phase area of the water storage tank by a pipeline provided with a control valve; an electric heating tube is arranged in the liquid phase area of the water storage tank; a pressure sensor is arranged at the top of the water storage tank. High pressure water vapor is introduced into the shaft seal from the outer end of the shaft seal, and the high water vapor is guaranteed to be always positioned in the shaft seal, so the problem that an ammonia water working medium leaks to the outside is solved, 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 water vapor as a sealing medium. Background technique [0002] 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 main sh...
