[0002] Thermal power plants usually refer to power plants that generate electricity by burning fossil fuels (such as coal, oil or natural gas). The core principle is to use the heat energy generated by fuel combustion to heat water, convert it into steam, and drive steam turbines to generate electricity. Thermal power plants are one of the most common forms of power generation in the world and are widely used to provide large-scale and stable power supply.

[0003] Reference is made to the authorized patent number "(CN218944664U)" which discloses a dust removal device for a coal conveying system in a thermal power plant, which records: "After use, it is necessary to move the rotating tube and insert the plug-in block into the spray head again, so that the spray head can be sealed, thereby preventing the spray head from being blocked due to dust entering and accumulating in large quantities in the spray head. When a certain amount of dust accumulates in the spray head, personnel can pull the rotating tube back and forth and use the unblocking block to unblock the spray head." It also records: "Most of the existing dust removal devices for coal conveying systems in thermal power plants are not equipped with a spray mechanism anti-blocking mechanism. Therefore, when they are placed in a dusty place, dust will enter and accumulate on the spray mechanism, which may block the spray mechanism, thereby causing certain inconvenience to personnel when using it."
