AI Technical Summary

Technical Problem

The baffles inside the decomposition tank detached due to the impact of water flow from the inlet pipe, resulting in a short residence time of the chlorate solution in the decomposition tank, insufficient mixing, and a low decomposition rate.

Method used

A drainage device is installed in the water inlet pipe of the decomposition tank, including a drainage head, a central frame, a driven plate, a support claw, a drive shaft, and an actuation handle. The rotation of the drive shaft and the driven plate causes the support claw to extend and be fixed on the inner wall of the water inlet pipe. The drainage head disperses the water flow and reduces the impact on the baffle plate.

Benefits of technology

The residence time of the chlorate solution in the decomposition tank was extended, ensuring thorough mixing of the solution and improving the decomposition rate of the decomposition tank.
