AI Technical Summary
Existing spray towers have nozzles that are either too dense or too sparse, resulting in uneven water flow and incomplete coverage of the tower's cross-section.
The nozzle design employs a staggered arrangement of the first, second, third, and fourth pipes, with the nozzles evenly distributed. The nozzle mechanism includes four nozzles, which pass through the center of the tower's cross-section to ensure uniform coverage and consistent water spray intensity.
It achieves uniform coverage of the spraying area and uniformity of water spray intensity, thus improving the waste gas treatment effect.

[0013] The utility model will be further explained in connection with the drawings and through examples.
[0014] As Figs. 1 to 3 shown, Fig. 3The middle meshing arc is the spraying range of each nozzle 31. The spraying tower in the embodiment comprises a tower body 1, an air inlet 21 is arranged on the lower end side wall of the tower body 1, an air outlet 22 is arranged on the upper end opening of the tower body, a spraying device 3 and a filler device 4 are arranged in the tower body 1, the spraying device 3 comprises nozzles 31 and water inlet pipes 32 communicated with the nozzles 31, the nozzles 31 are hollow cone nozzles, the hollow cone nozzles are used for atomizing the spraying liquid, the filler device 4 comprises fillers 41, support plates 42 used for supporting the fillers 41, pressing plates 43 used for preventing the fillers 41 from being blown away by the rising airflow, the fillers 41 are located between the support plates 42 and the pressing plates 43, and the fillers 41 are multi-faceted hollow spheres or Raschig rings. The nozzles 31 are arranged on a nozzle mechanism 33, the nozzle mechanism 33 comprises a first pipe 34 communicated with the water inlet pipes 32 and passing through the center of the cross section of the tower body 1, four nozzles 31 are arranged at equal intervals on the first pipe 34, a second pipe 35 is vertically arranged at the center of the first pipe 34, four nozzles 31 are arranged at equal intervals on the second pipe 35, a third pipe 36 and a fourth pipe 37 are arranged in parallel with the second pipe 35 above and below the second pipe 35 respectively, two ends of the third pipe 36 and the fourth pipe 37 are respectively provided with nozzles 31, and the interiors of the first pipe 34, the second pipe 35, the third pipe 36 and the fourth pipe 37 are communicated. The lengths of the first pipe 34 and the second pipe 35 are the same, the lengths of the third pipe 36 and the fourth pipe 37 are the same, and the lengths of the first pipe 34 and the second pipe 35 are greater than the lengths of the third pipe 36 and the fourth pipe 37.
