[0022] It should be noted that the user can control the first three-way pipe 6 and the hollow tube 7 to rotate in opposite directions through the power mechanism 11. While the hollow tube 7 rotates, the second three-way pipe 8 is controlled to rotate by the linkage mechanism 12. The first three-way pipe 6 rotates horizontally while driving the second three-way pipe 8 to rotate, and at the same time cooperates with the second three-way pipe 8 to rotate vertically to drive the spray head 9 to spray the alkaline solution on the interior of the reaction tower body 1 without dead angles, thereby achieving the alkaline solution spraying without dead angles inside the reaction tower body 1, thereby improving the flue gas desulfurization purification effect, and solving the problem that although the current flue gas purification reaction tower can desulfurize and purify the flue gas through the spray assembly, the spray assembly inside it has a single direction, and the sprayed alkaline solution has dead angles, resulting in poor flue gas desulfurization purification effect.

[0023] In a further preferred embodiment of the present invention, Figure 2 As shown, the power mechanism 11 includes: a first bevel gear 13 is arranged inside the gear box 10, the first bevel gear 13 is fixed to the outer surface of the output end of the motor 14, and the motor 14 is fixedly connected to the gear box 10; both ends of the first bevel gear 13 are meshed with second bevel gears 15, and the two second bevel gears 15 are respectively fixed to the outer surfaces of the hollow tube 7 and the first three-way tube 6.

The two second bevel gears 15 respectively drive the hollow tube 7 and the first three-way tube 6 to rotate in the opposite direction, thereby providing rotational power for the hollow tube 7 while controlling the first three-way tube 6 to rotate in the horizontal direction.

[0025] In a further preferred embodiment of the present invention, Figure 3 As shown, the linkage mechanism 12 includes: a third bevel gear 16 is fixedly connected to the bottom outer surface of the hollow tube 7, and fourth bevel gears 17 are meshed on both sides of the third bevel gear 16; two fourth bevel gears 17 are respectively fixed to the outer surface of the second three-way pipe 8.
