Metal smelting superfine flue gas solid-phase adsorption treatment device

The utility model relates to a solid-phase adsorption treatment device for metal smelting superfine flue gas, which adopts solid-phase particles to circularly adsorb tiny dust in the metal smelting superfine flue gas. INTEGRATED SUPPORT PLATFORM, a transverse inlet of the air inlet pipe directly faces the purification space; an outlet of the air inlet pipe faces upwards and is communicated with aninlet of the throat pipe; an outlet of the throat pipe is communicated with an inlet of the expansion decelerating pipe; an outlet of the expansion speed reducing pipe is communicated with an inlet of the gas-solid mixer; an outlet of the gas-solid mixer is communicated with an inlet of the cyclone separator; the device and the method have the advantages that harmful substances in the metal smelting superfine flue gas are continuously adhered to the porous calcium carbonate particles by adopting the solid-phase adsorption device and the solid-phase adsorption method; compared with the prior art, the purification of t
