[0002] The commonly used calcination facilities for calcining bulk materials are vertical kiln vacuum calcining furnaces, such as calcining ore, mineral pellets, limestone, dolomite, metal materials, etc. The existing calcining furnaces mostly adopt a single vertical kiln structure, that is, the materials are added from the top of the vertical kiln, and the calcined bulk materials are discharged from the bottom, while the fuel and combustion-supporting air enter the bottom of the vertical kiln for combustion, and the exhaust gas is discharged from the top of the vertical kiln. Metal heat storage blocks are often used to store heat energy, so that the heat energy of the exhaust gas can be effectively utilized.

[0003] In a limestone calcining flue gas desulfurization device disclosed in the Chinese utility model patent application disclosure CN218924258U, the smoke passing through the eccentric bend will flow along the pipe wall of the eccentric bend, at which time water vapor will gather into droplets on the pipe wall, and the water droplets will flow down along the pipe wall of the flue gas pipe, thereby greatly reducing the humidity of the flue gas and reducing the sulfur content in the emission, but the desulfurization effect cannot be improved, and the sprayed desulfurization liquid cannot be collected. For this reason, we propose a desulfurization structure of a double vertical kiln calcining furnace. Utility Model Content
