Description

Technical Field

[0001] The utility model relates to the technical field of industrial steam supply for steam turbines, in particular to an industrial steam supply device for steam turbines. Background Art

[0002] A steam turbine is a rotary steam-powered device, also known as a steam turbine engine. It uses high-temperature, high-pressure steam to accelerate through fixed nozzles and then spray onto blades, rotating a bladed rotor and performing external work. The primary function of a steam turbine is to convert steam energy into mechanical work. It is an external combustion rotary machine. This conversion process occurs within the turbine, where a series of annular nozzles and moving blades convert the steam's thermal energy into mechanical energy, which drives the turbine's rotor.

[0003] In Chinese Patent No. 202221455924.7, the utility model discloses a steam supply optimization device for a low-pressure shaft seal of a steam turbine, comprising a main connecting mechanism, a water spray cooling mechanism, and an external protection mechanism. The water spray cooling mechanism is disposed on the right side of the main connecting mechanism, and the external protection mechanism is disposed around the water spray cooling mechanism. This steam supply optimization device for a low-pressure shaft seal of a steam turbine provides a throttling and combing effect for its overall water supply process through a throttle valve and a steam trap. The throttle valve is arranged in two groups in conjunction with the transmission pipeline, enabling multi-way combined control according to usage needs, meeting flexible water drainage adjustment. Water is then transmitted to the cooling water regulating valve through the interconnecting pipelines. The cooling water regulating valve controls the cooling water flow rate based on temperature detection. The cooling water nozzle disposed on the left side then transmits the cooling water to the steam-water separator to generate steam. The steam supply to the low-pressure shaft seal is completed through the steam supply main pipe, solving the problem of unstable low-pressure shaft seal temperature, the inability to maintain the temperature within the required range, and the large temperature difference between the two sides.

[0004] The existing industrial steam supply device for steam turbines uses flanges to connect the pipelines. During the steam supply process, the gas needs to be compressed before it can be circulated and transported between the pipelines. The pipelines need to withstand a large air pressure. If they rely solely on flange connections, after being subjected to high pressure for a long time, the connection may become unstable, leading to gas leakage, etc. If the operator is unable to get timely maintenance, there will be a major safety hazard.

[0005] Therefore, in order to solve the above problems, an industrial steam supply device for a steam turbine is proposed. Utility Model Content
