Synthetic ammonia waste gas desulfurization device

The utility model belongs to the technical field of waste gas desulfurization, particularly relates to a synthetic ammonia waste gas desulfurization device, and aims to solve the problem that the desulfurization efficiency is influenced due to the fact that a conventional synthetic ammonia waste gas desulfurization device is poor in waste gas cooling effect. The bottom of the conveying pipe communicates with a nozzle; the cooling assembly comprises a cooling box, a cooling pipe and a stirring assembly, a communicating pipe is communicated between the cooling box and the desulfurizing tower, the bottom of the cooling pipe is communicated with a plurality of vertical pipes, the bottom ends of the plurality of vertical pipes are communicated with spraying barrels, the spraying barrels are fixedly mounted in the cooling box, the bottom of each spraying barrel is communicated with a plurality of spraying heads, and the stirring assembly comprises a transverse shaft and a vertical shaft. A plurality of first stirri
