Cyclone pneumatic vortex desulfurization emulsifier and vortex emulsification desulfurization tower with Venturi tubes

The utility model relates to a desulfurization emulsifier and a desulfurization tower. The desulfurization emulsifier comprises a cylinder wall, a helical cone, and blades which are slantways arranged between the cylinder wall and the helical cone, wherein sawteeth are formed on the edge of the upper part of each blade; and the two adjacent sawteeth oppositely bend toward two sides to form an included angle. The desulfurization tower comprises an inlet flue, a desulfurization tower shell, a flue gas cooling device, hot rolled floor plates, a slurry spraying device, flow-stabilizing plates, a defogger flushing device, a defogger, an outlet flue, a circulating slurry pond and a desulfurizing slurry circulation pump, wherein Venturi tubes which are taken as flue gas desulfurization channels are arranged between the upper and lower hot rolled floor plates; and the cyclone pneumatic vortex desulfurization emulsifier is arranged at a throat in each Venturi tube. The desulfurization tower has the advantages that gas
