[0029] It can be seen from the above content that the upper surface of the bottom shell 11 is an inclined structure, so that water can slide down to the bottom of the desulfurization tower 1 and be collected and recovered in the water tank 2 for recycling.

[0030] It can be seen from the above content that the inner pipe 9 is annular in structure as a whole, and a covering structure is added so that water can evenly cover the inside of the desulfurization tower 1.
