Among them, the water outlet 111 is in communication with the input end of the circulation pump pipeline 4, and the output end of the circulation pump pipeline 4 is in communication with the water inlet pipeline 5. That is, the water in the water storage chamber 11 is sucked by the circulation pump pipeline 4 and enters the water inlet pipeline 5 for spraying the gas by the spray pipe 6 and then flows back to the water storage chamber 11.

[0030] In order to facilitate the introduction of gas into the interior of the spray tower, a first pipeline 21 is provided in the middle of the first tank 2. The first pipeline 21 is provided with a first inlet 211 and a first outlet 212, and the first outlet 212 is in communication with the interior of the first tank 2.

[0031] Further, preliminary spraying of the gas is carried out in the first pipeline 21.

Furthermore, to prevent the water from entering the circulation pump pipeline 4 after being discharged from the water outlet 111 and bringing impurities into the circulation pipeline, causing subsequent spray blockage, a filter net is provided at the end of the water outlet 111. Furthermore, since the water flows from the second pipe 31 into the water storage chamber 11 after the gas is sprayed by the second pipe 31, to prevent impurities from accumulating at the water outlet 111, referring to Figure 1 , a baffle 7 is provided in the water storage chamber 11.
