Problems solved by technology

[0003] In the prior art, when high-temperature steam passes through the turbine cavity, part of the water vapor will be liquefied into water droplets, and most of the liquefied water will be discharged directly, and since the liquefied water still has a relatively high temperature, obviously this will cause waste of heat energy At the same time, the direct discharge of high-temperature water will also cause the greenhouse effect, which is not friendly to the environment

Embodiment Construction

[0057] In order to make the objectives, technical solutions and advantages of the present invention more clear, the present invention will be further described in detail below through the accompanying drawings and embodiments. However, it should be understood that the specific embodiments described herein are only used to explain the present invention, and not to limit the scope of the present invention.

[0058] It should be noted that, when an element is referred to as being "disposed on, provided with" another element, it may be directly on the other element or there may also be intervening elements, when an element is referred to as being "connected, connected" to another element An element may be directly connected to another element or there may be an intervening element at the same time, "fixed connection" means fixed connection, there are many ways of fixed connection, not as the protection scope of this article, the terms used in this article "Vertical," "horizontal,"...

Abstract

The steam turbine circulating water system maintenance system comprises a steam turbine body, one end of the steam turbine body is provided with a steam inlet pipe allowing steam to enter the steam turbine body, and the other end of the steam turbine body is provided with a steam outlet pipe allowing steam in the steam turbine body to be discharged. The steam turbine body is further provided with a water circulation assembly, and a maintenance assembly is arranged in the water circulation assembly. According to the water circulation assembly, water obtained after water vapor in the steam turbine body is liquefied can be vaporized again, enters the steam inlet pipe and then enters the steam turbine body through the steam inlet pipe to push an impeller in the steam turbine body to rotate, and therefore waste of heat energy is avoided; and the greenhouse effect caused by the fact that high-temperature water obtained after water vapor in the steam turbine body is liquefied is directly discharged from the bottom of the steam turbine body is avoided.

Description

technical field [0001] The invention relates to the technical field of steam turbines, in particular to a system and method for overhauling a circulating water system of a steam turbine. Background technique [0002] A steam turbine, also known as a steam turbine engine, is a rotary steam power device. The high-temperature and high-pressure steam passes through a fixed nozzle to become an accelerated airflow and then sprays it onto the blades, so that the rotor equipped with the blade row rotates and performs external work at the same time. The main equipment of thermal power plants is also used in metallurgical industry, chemical industry, and ship power plants. [0003] In the prior art, when high-temperature steam passes through the turbine cavity, part of the water vapor will be liquefied into water droplets, and most of the liquefied water will be directly discharged. Then, since the liquefied water still has a relatively high temperature, it will obviously cause waste ...
