They reduce and render harmless waste through high-temperature incineration and utilize waste heat to generate electricity and achieve resource utilization. During operation, waste-to-energy plants generate a large amount of fly ash, which needs to be treated.

[0003] In existing technologies, fly ash is first filtered through a filter screen during treatment. However, cleaning the filter screen is inconvenient, and it is easily clogged by impurities, affecting the filtration effect. Therefore, we propose a fly ash treatment device suitable for waste incineration power plants to solve the above problems. Utility Model Content

[0013] Compared with the prior art, the advantages of this utility model are: When the filter plate needs cleaning, the first motor drives the drive gear to rotate, which in turn drives the driven gear to rotate, which in turn drives the rotating shaft to rotate. The rotating shaft then drives the cleaning brush to rotate, which brushes off the impurities attached to the filter plate. Then, the second motor drives the screw to rotate, causing the lifting plate, which is threadedly connected to the screw, to move downward. The lifting plate moves the hollow plate downward, aligning the flushing holes with the filter plate. The water pump is then started, and water is drawn through the water pipe. The water enters the hollow plate and is sprayed onto the filter plate through multiple flushing holes to backwash the filter plate. This invention uses a cleaning brush to remove impurities adhering to the filter plate, and then backwashes the filter plate, which can effectively clean the filter plate and prevent clogging.
