Industrial steam turbine capable of emergently stopping and recovering waste heat for power generation

Abstract

The invention discloses an industrial steam turbine capable of emergently stopping and recovering waste heat for power generation. The industrial steam turbine comprises a steam turbine body, whereina circular-truncated-cone-shaped supporting plate is arranged inside the steam turbine body, a circular-truncated-cone-shaped shaking supporting plate is arranged inside the supporting plate, a main power shaft is rotationally arranged between the left wall and the right wall inside the shaking supporting plate, and the left end surface of the main power shaft extends to the left side of the steamturbine body, and serves as power to be output other machine equipment. According to the industrial steam turbine, the rotation of the steam turbine is stabler by self-adjusting the rotating speed ofthe steam turbine, the device performs more efficient waste heat recovery, and meanwhile, when the rotating speed of the steam turbine exceeds a critical point, the risk that the steam turbine breaksdown due to the fact that the rotating speed is too large is greatly reduced by reducing the acceleration power of the steam turbine and braking a rotating shaft, and exhausted air is recycled againwhen the rotating speed is too large, so that waste heat recovery of the steam turbine becomes more efficient and stabler.

Description

technical field [0001] The invention relates to the technical field of steam turbines, in particular to an industrial steam turbine capable of emergency shutdown and waste heat recovery for power generation. Background technique [0002] In our daily life, a steam turbine is a rotary steam power device. The high-temperature and high-pressure steam passes through a fixed nozzle to become an accelerated air flow and is sprayed onto the blades, so that the blade rotors rotate and do work externally. Ordinary industrial steam turbines operate at speeds exceeding After the limit speed, it will cause high-speed vibration of the device and cause vibration damage to other connected parts. Ordinary industrial steam turbines cannot achieve good real-time speed control, and cannot achieve a good emergency stop effect. The waste heat is well recovered and recycled. The present invention illustrates a device capable of solving the above-mentioned problems. Contents of the invention ...
