Description

Technical Field

[0001] The utility model relates to the technical field of collection devices, in particular to a steam turbine leakage collection device. Background Art

[0002] A steam turbine is a rotary steam power device. High-temperature and high-pressure steam passes through a fixed nozzle and becomes an accelerated airflow, which is then sprayed onto the blades, causing the rotor with blade rows to rotate and perform work externally. It is the main equipment in modern thermal power plants and is also used in the metallurgical industry, chemical industry, and ship power devices. After a steam turbine has been running for a long time, the shaft seal steam leakage problem is more common. The leaked steam has a large thermal enthalpy value, which is easy to cause heat energy loss.

[0003] In order to reduce the heat energy loss caused by turbine leakage, the prior art proposes a turbine shaft seal leakage collection and discharge device with patent publication number CN220415477U, which uses a cover to completely wrap the outside of the high-pressure shaft seal, connects the steam pipe to lead it outside the turbine room, and installs an exhaust fan at the end of the pipe. When the exhaust fan is running, a micro-negative pressure effect is formed in the added cover, and the shaft seal leakage steam is discharged to the outside through the exhaust fan, reducing the impact on the turbine. Although it is convenient to reduce heat energy loss and collect heat energy, it is not convenient to block the leakage according to the actual collection situation, which is easy to affect the subsequent heat energy collection effect.
