When purifying the flue gas, most of the desulfurization and denitrification are carried out through spraying technology. The Chinese utility model patent, authorization announcement number "CN218653828U" discloses a flue gas desulfurization spraying mechanism. The utility model uses the accumulated liquid medicine at the bottom of the inner wall of the lower shell to initially filter the flue gas, and then sprays the liquid medicine longitudinally and transversely through the wall plate and the spray head on the connecting pipe, which increases the range and angle of the liquid medicine spraying, reduces the spraying dead angle, and realizes the second filtration of the rising flue gas, so that the liquid medicine and the flue gas react more fully, thereby improving the purification effect of the flue gas.

[0003] During use of the above technical solution, although longitudinal and transverse spray heads are set to reduce spraying dead angles, there are still places where spraying is not in place, and uniform spraying cannot be achieved.
