Due to the characteristics of the desulfurization equipment, the structure of the existing spray gun and the lifting mode, the existing spray gun mounting/dismounting mode has a plurality of inconveniences and potential safety hazards. Taking the disassembly of the spray gun as an example, when the spray gun needs to be replaced, the spray gun is firstly required to be lowered below the secondary platform through a lifting system of the desulfurization device, then a lifting hook of the travelling crane is used for lifting a lifting point of the desulfurization spray gun, then a quick clamping device is opened to disconnect the desulfurization spray gun from the lifting device, and after the lifting system is lifted, the travelling crane drags the desulfurization spray gun out of the two-layer platform and then lifts off. Because the center of the travelling crane lifting hook and the center of the spray gun are offset by about 500-1000mm, when the spray gun is pulled, the spray gun is obliquely pressed on the wall of the platform hole and is pulled out of the platform along the hard direction. Because the spray gun is heavier (weighing about 1-1.5 tons), and the refractory material is paved on the outer wall of the spray gun, the refractory material is easy to damage when pulled out to influence the service life of the spray gun, and the spray gun is easy to be blocked with the upper edge of the hole wall when pulled out obliquely, the crane position needs to be frequently adjusted, and the safety hazard to surrounding personnel is large.
