The utility model relates to the technical field of desulfurization towers, and provides a desulfurization spraying device of a desulfurization
tower, which comprises a
barrel body, a conveying
pipe, a
pipe frame, a spraying head, a fixing plate, an adjusting rod, an adjusting mechanism, a driving mechanism and a mixing mechanism, the
barrel body is provided with an air inlet hole, the conveying
pipe is arranged in the air inlet hole, the pipe frame is arranged in the
barrel body, the pipe frame is communicated with the conveying pipe, and the spraying head is arranged in the barrel body. The multiple spraying heads are arranged, the fixing plate is arranged in the barrel, the multiple adjusting rods are arranged in the barrel, the multiple spraying heads are arranged on the fixing plate and the adjusting rods respectively, the adjusting mechanism is arranged in the barrel, the driving mechanism is arranged in the barrel, and the mixing mechanism is arranged on the fixing plate. The problems that in the prior art, most spray headers are fixed, the spray direction is fixed, after
waste gas drifts to other positions, the
waste gas is difficult to make uniform contact with spray liquid, the phenomenon of incomplete desulfurization is easily caused, and the desulfurization efficiency is affected are solved.
