[0002] Dust pollution is the most common type of pollution in my country, especially the pollution caused by coal-fired enterprises such as thermal power plants. At present, most thermal power plants' generator sets are equipped with dust removal and filtration systems to ensure that the pollution caused by the enterprises meets national standards. Thermal power plants usually use pneumatic dust removal devices.

[0027] like Figure 1-5 As shown, a scraper assembly 4 is provided inside the input cylinder 2 for scraping off dust adhering to the inner wall of the input cylinder 2 and separating the ash gas. The scraper assembly 4 includes a rotating shaft 41. The top of the rotating shaft 41 is connected to the top of the input cylinder 2 through a bearing. Trapezoidal scraper rods 42 are fixed on both sides of the top of the rotating shaft 41, and the trapezoidal scraper rods 42 are in contact with the inner wall of the input cylinder 2.

[0028] A number of evenly distributed stirring rods 43 are fixed on the rotating shaft 41, a filter bucket 45 is fixed on the bottom of the input cylinder 2, and the filter bucket 45 is arranged at the top of the barrel 1 to facilitate ash and gas separation, a motor 44 is fixed at the top center of the input cylinder 2, the output shaft of the motor 44 passes through the top of the input cylinder 2 and is fixedly connected to the top of the rotating shaft 41, and the bottom of the trapezoidal scraper rod 42 is in contact with the inner wall of the filter bucket 45, so that the motor 44 drives the rotating shaft 41 to rotate, and a control panel 8 for controlling the operation of the motor 44 and the electric valve 6 is fixed on the top of the barrel 1.

[0029] By setting the scraper assembly 4, the control panel 8 is operated to control the electric valves 6 on the two connecting pipes 5 to open and quantitatively introduce the ash gas into the barrel 1 through the input cylinder 2. Then, the control panel 8 is operated to control the motor 44 to work. The motor 44 drives the rotating shaft 41 to rotate. The rotation of the rotating shaft 41 drives the several stirring rods 43 on it to rotate, thereby stirring the ash gas inside the input cylinder 2.

The rising of the blocking ball 73 causes the dust accumulated on the top of the filter bucket 45 to be concentrated into the ash collecting barrel 71. Finally, the bottom cover 14 is unscrewed to discharge the dust inside the ash collecting barrel 71, thereby realizing the ash removal process in the thermal power plant.
