AI Technical Summary

Technical Problem

The existing rotary spray gun is prone to the adhesion of irregular molten slag at the slag line position, which causes eccentric vibration, limits the rotation speed, affects the desulfurization efficiency and desulfurizing agent utilization rate, and has high equipment maintenance costs.

Method used

A double-layer agitator structure is designed, including an anti-slagging agitator assembly and a main agitator assembly. The anti-slagging agitator assembly induces forced vortices in the slag line region, and the main agitator assembly performs effective stirring at high speed. By optimizing the blade geometry and installation angle, a stable flow field is formed to prevent molten slag adhesion.

Benefits of technology

It achieves stable operation at high speed, improves desulfurization efficiency and desulfurizer utilization, reduces equipment maintenance costs, and extends the service life of the spray gun.

Abstract

The invention relates to the field of metallurgical equipment, and discloses a double-layer stirring paddle desulfurization spray gun for inhibiting eccentric vibration and a use method thereof. The desulfurization spray gun comprises a rotating shaft, an anti-slagging stirring paddle assembly and a main stirring paddle assembly. The anti-slagging stirring paddle assembly is connected to the rotating shaft and comprises a plurality of first stirring blades, and the first stirring blades have set geometrical shapes and installation angles, so that the first stirring blades can induce generation of forced vortexes in a slag layer in a slag line area when rotating. The main stirring paddle assembly is connected to the rotating shaft and located below the anti-slagging stirring paddle assembly. According to the desulfurization spray gun, the anti-slagging stirring paddle assembly on the upper layer is arranged, forced vortexes are induced to be generated in a slag line area, active constraint and isolation of slag are achieved, contact and adhesion of the slag and the gun body are avoided, the eccentric slagging phenomenon is restrained from the source, and the premise and guarantee are provided for high-rotating-speed stable operation of the spray gun; and adhering of desulfurizer residues on the surfaces of the blades and the connecting parts is effectively avoided.
