The water pump 32 is connected to the middle of the annular pipe 33 through a connection pipe, and the first nozzles 34 are uniformly arranged below the annular pipe 33 with the spraying direction facing downward. When the first-stage spray assembly 3 is used, the water in the cooling water tank 31 is supplemented into the annular pipe 33 through the connecting pipe by the water pump 32 and then is sprayed out from each first nozzle 34; meanwhile, the driving assembly drives the annular pipe 33 to rotate, and when the annular pipe 33 rotates, the first nozzles 34 are driven to rotate, so that the first nozzles 34 spray liquid and rotate at the same time, the liquid is thrown out in a larger range, and the contact area of the liquid and the waste gas is larger.

As shown in fig. 1, the secondary spray assembly 4 includes: a vertically arranged spray pipe 41, a plurality of second nozzles 42 arranged on the spray pipe 41; the upper end of the spray pipe 41 is communicated with the annular pipe 33, and each second nozzle 42 faces the inner side wall of the tower body 1. Specifically, when the secondary spray assembly 4 is used, the driving motor 35 drives the annular pipe 33 to rotate, and liquid in the annular pipe 33 flows into the spray pipe 41 and is sprayed out of the second nozzles 42 to the inner side wall of the tower body 1, so that the liquid can be fully contacted with waste gas flowing along the inner side wall of the tower body 1.

As shown in fig. 1, the driving assembly drives the annular tube 33 to rotate through a transmission assembly 5; the transmission assembly 5 comprises: a driving gear 51 and a driven gear 52 which are positioned above the annular tube 33 and engaged with each other; the driving gear 51 is mounted on the rotor of the driving motor 35, the driven gear 52 is mounted with a rotating shaft, the lower end of the rotating shaft is communicated with the middle part of the annular pipe 33, and the upper end of the rotating shaft is connected with the connecting pipe 33 through a rotary joint. Specifically, when the transmission assembly 5 is used, the driving motor 35 drives the driving gear 51 to rotate, so as to drive the driven gear 52 to rotate, further drive the annular pipe 33 to rotate, and the annular pipe 33 drives the first nozzle 34 to rotate; at this time, the water pump 32 supplies the liquid in the cooling water tank 31 from the connection pipe to the ring pipe 33, and then the liquid is discharged from the respective first nozzles 34, and the first nozzles 34 rotate while spraying the liquid, so that the range in which the liquid is thrown out is wider, and the contact area with the exhaust gas is larger.

As shown in fig. 1, in the present embodiment, each of the first nozzle 34 and the second nozzle 42 is covered with a filter 6, and the filter 6 may be, but is not limited to, filter cotton, which can reduce the clogging of the nozzles caused by impurities in the exhaust gas.
