[0005] However, the processing platform has the following defects when used:

[0006] 1. The existing automatic control device can automatically control and remind the exhaust gas in the exhaust gas conveying pipeline. However, when the exhaust gas is conveyed through the pipeline auxiliary control device, the exhaust gas backflow prevention effect and the warning light synchronous protection effect are not high, which can easily cause different air pressures in the pipeline, resulting in exhaust gas backflow, reducing wastewater conveying efficiency, and affecting the effect of restorative exhaust gas treatment. At the same time, the warning light is exposed to the outside for a long time, which will cause dust to be adsorbed on the surface of the warning light, causing the clarity of the warning light to decrease, affecting the staff to grasp the exhaust gas conveying status in the pipeline through the control device in the first time;

[0007] 2. The existing automatic control device has a relatively fixed height for the use of the conveying pipeline, and when the exhaust gas is placed idle through the pipeline, the end of the pipeline is often exposed to the outside, and the sealing protection effect of the pipeline inlet and outlet is not high, which can easily cause dust to enter the inner wall of the pipeline through the inlet and outlet, causing the air pressure accuracy inside the pipeline to decrease. In addition, when different exhaust gas treatment equipment is used through the pipeline, the discharge outlet heights of different exhaust gas treatment equipment are different, which reduces the flexibility of the conveying pipeline docking installation.
