The working principle of the technical scheme is as follows:
according to the requirement condition of the coagulant, the preparation of the coagulant is preferentially ensured, and when the coagulant bin is full, the coagulant is automatically switched into a recycling mode, and the concrete steps are that:
1. when the level of the accelerator use bin 12 is above the neutral level, the system automatically recognizes that the accelerator storage is sufficient and automatically switches to the reuse mode. At the moment, the first pipe chain machine 3 is started, the first flashboard is opened, the material (collected dust/three-control collected dust) output by the first discharge port is conveyed to the belt conveyor 2 through the first pipe chain machine 3, and the desulfurized gypsum enters the calcination system through the belt conveyor 2.

The beneficial effects of the technical scheme are as follows:
1. in the invention, the dust collection ash can preferentially ensure the preparation of the coagulant according to the requirement of the coagulant; when the accelerator bin is full, the recycling mode is automatically switched. Therefore, the invention can effectively realize the full-automatic recycling of the dust collection ash, and the application can realize the comprehensive utilization of the three-control dust collection ash.

3. The mode of conveying the dust collection ash to the belt conveyor 2 can realize the quantitative dynamic blending of the dust collection ash and the desulfurized gypsum, and has a very good mixing effect.
4. The coagulant prepared by the ball mill 9 is conveyed pneumatically by the Roots blower 11 and enters the coagulant use bin 12 along the conveying pipeline 10, so that the whole coagulant preparation process is completed, the manual operation time is saved, and the production efficiency is greatly improved.
