[0002] With the development of the times and the advancement of science and technology, electricity has become an indispensable energy source in people's lives. Thermal power generation is an important way of power generation. Thermal power generation uses a combustion furnace to generate steam, and then converts the steam into electricity through a steam turbine.

[0003] However, in the prior art, the filter screen is damaged after long-term use or too many impurities remain, resulting in the mesh being blocked and it is difficult to conveniently remove and clean it.

[0004] For example, an environmentally friendly thermal power generation boiler disclosed in Chinese patent CN214172567U has a disassembly mechanism. After long-term use of the device, the filter can be removed from the filter box to clean the stains remaining on the filter, thereby avoiding the situation where the holes on the filter are completely blocked due to long-term non-cleaning and the device cannot operate. The service life of the filter is increased and the practicality of the device is made stronger. The cover mechanism can be used to seal the smoke outlet pipe when the device is idle to avoid debris entering from the smoke outlet pipe and affecting the function of the filter box, thereby eliminating some potential safety hazards.

[0005] However, the filter screen needs to be frequently removed and cleaned during use, which is cumbersome and inconvenient to use.

[0006] For this reason, we urgently need to provide an environmentally friendly thermal power generation boiler that increases the service life of the filter screen. Utility Model Content
