Compound fertilizer needs to be dried during the production process, which will produce a large amount of high-temperature dust-containing exhaust gas.

[0003] For example, in the patent document with the existing patent application number 202022641753.4, a beating dust removal type bag filter is disclosed, and it is specifically disclosed that the bag filter includes a box, a filter bag, an air inlet, and a clean air outlet. Several filter bags are arranged in the box, and the air inlet and the clean air outlet are arranged on both sides of the box. A rotating rod is rotatably connected in the box, and several clappers for beating the filter bags are distributed on the rotating rod. A rotating mechanism is installed on two adjacent boxes, and the rotating mechanism is connected to the rotating rod. A dust collection mechanism is arranged at the bottom of the box.
