[0002] At present, some harmful flue gases are generated in the industrial production process. Most of these flue gases contain harmful gases such as sulfur dioxide and nitrogen oxides, which are discharged into the atmosphere, causing acid rain and damaging the ecological environment. In the process of desulfurization of flue gas, a desulfurization tower is needed.

[0003] At present, a large amount of waste liquid will accumulate on the bottom side of the inner wall of the flue gas desulfurization tower during the process of desulfurizing the flue gas, and the waste liquid contains a large amount of solid pollutants. It is difficult for the existing flue gas desulfurization tower to separate the liquid accumulated at the bottom of the tower from solid and liquid, which makes it difficult to reuse the waste liquid, reduces the environmental protection of the flue gas desulfurization tower, and is inconvenient for operators to use. In addition, the flue gas flow rate inside the existing flue gas desulfurization tower is too fast, which makes it difficult for the flue gas to fully contact with the liquid, thereby reducing the quality of flue gas desulfurization, which is not conducive to the normal use of the flue gas desulfurization tower and reduces the practicability of the flue gas desulfurization tower.

A vent is opened through the bottom of the connecting box, and a mounting groove is opened through the top of the connecting box.
