[0038] A spray tower in the present embodiment can switch between coarse holes and fine holes 5 when the connecting pipe 4 is installed in the drain pipe 2, so as to control the size of the discharged water flow, thereby achieving the purpose of regulating the flow rate, improving the practicality of the tower body 1, and through the revolution of multiple drain pipes 2, the sprayed sodium hypochlorite can be evenly contacted with hydrogen cyanide, thereby improving the purification efficiency of hydrogen cyanide.

[0039] The working principle of the above embodiment is as follows: first, external sodium hypochlorite enters the rotating tube 12 through the water inlet pipe 24, and hydrogen cyanide enters the tower body 1 through the air inlet pipe 25.

During the rotation of multiple threaded barrels 16, multiple threaded rods 17 can be driven to rise and push the sliding ring 6 to bulge. When the sliding ring 6 bulges, it can push the connecting pipe 4 to slide in the drain pipe 2, so that the fine hole 5 coincides with the water inlet of the atomizing nozzle 3. At this time, the flow of sodium hypochlorite discharged will be adjusted, which can save the discharge of sodium hypochlorite, achieve the purpose of adjusting the flow, and improve the practicality of the tower body 1.
