Problems solved by technology
[0003] In the prior art, the blades of the steam turbine will produce impurities when receiving steam, which is difficult to clean, and the blades of the steam turbine used in industry are relatively large, which is inconvenient to take out for cleaning, and because the steam turbine is used as a power source, the cost of shutting down for cleaning is relatively high; for this reason, we Provide a cleaning mechanism for steam turbine blade fouling and a cleaning method based on the mechanism to solve the above problems

Embodiment Construction
[0029] 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.
[0030] 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,"...

The invention discloses a cleaning mechanism for fouling of steam turbine blades and a cleaning method based on the mechanism, comprising a casing covering the outside of multiple sets of steam turbine blades. When water is introduced into the steam turbine blades for cleaning, the impact force of the water can drive the steam turbine blades Keep rotating without stopping the operation of the steam turbine, and the water can be flushed between the adjacent steam turbine blades in a spiral trajectory through the guide plate in the casing, and also includes receiving the water discharged from the water outlet pipe and continuing to discharge the received water from the water inlet pipe. The circulation box in the shell is provided with a filter mechanism that forms a one-way circulation channel and provides one-way circulation of the water in the circulation box to filter out impurities in the water. The water for washing the blades can be discharged into the circulation box through the filter mechanism After filtering, it is discharged into the casing again for cleaning the turbine blades, and the water in the filter mechanism is filtered repeatedly and then enters the casing to wash the turbine blades, which ensures that the water used for washing the turbine blades does not contain impurities. Good cleaning effect.
Description
technical field [0001] The invention relates to the technical field of steam turbines, in particular to a cleaning mechanism for fouling of steam turbine blades and a cleaning method based on the mechanism. 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 does external work at the same time. Steam turbines are the main equipment of modern thermal power plants, and are also used in metallurgical industry, chemical industry, and ship power plants. [0003] In the prior art, when the blades of the steam turbine receive steam, impurities are generated, which is difficult to clean, and the blades of steam turbines used in the industry are large and inconvenient to take out for cleaning. A cleaning mechanism for fo...
