Spray gun head, spray gun and desulfurization method

The invention discloses a spray gun head, a spray gun and a desulfurization method. The spray gun head comprises a gun head body, the central pipe is a linear pipeline and is arranged in the middle of the gun head body; the inlets of the two side blowing pipes are connected to the outlet of the central pipe; on a first projection plane parallel to the axis of the spray gun head, the projections of the two side blowing pipes and the central pipe form a herringbone shape, and the projections of the side blowing pipes are smoothly connected with the projection of the central pipe; and on a second projection plane perpendicular to the axis of the spray gun head, the projections of the two side blowing pipes are S-shaped. The gun head is in the herringbone arc shape and has a good blowing desulfurization effect, smooth transition is achieved, pipeline resistance is greatly reduced, kinetic energy of a desulfurizing agent outlet is greatly improved, kinetic energy loss is reduced to 12% from original 63%, and the p
