High-temperature wear-resistant corrosion-resistant pressure type spray gun with special nozzle

The invention provides a high-temperature wear-resistant corrosion-resistant pressure type spray gun with a special nozzle, which comprises a spray gun body, the length of the spray gun body can be adjusted according to the size of a drying tower, the nozzle is arranged at the front end of the spray gun body, and an interface flange connected with the drying tower sleeves the rear section of the spray gun body and can be adjusted according to different drying towers. The rear section is provided with a connector flange overflowing medium connector serving as a desulfurization wastewater inlet, desulfurization wastewater enters from the overflowing medium connector, sequentially passes through the spray gun body, the nozzle body, the rotary vane and the spray piece, is atomized at the nozzle and enters a drying tower to be evaporated. The atomization effect of the nozzle on desulfurization waste water can be improved, the nozzle is not prone to being blocked, abraded and corroded, the service life of the nozzl
