An integrated desulfurization and dust removal device for sulfur-containing flue gas
ActiveCN117695835BActive adjustmentRealize automatic adjustmentGas treatmentTransportation and packagingFlue gasDust control
This invention relates to an integrated desulfurization and dust removal device for sulfur-containing flue gas, belonging to the field of dust removal and desulfurization technology. Considering the issue of uneven flue gas flow as it passes through the adsorption spheres in the granular desulfurization chamber, a deflection base with a ball seat is creatively designed. An adjusting rope assembly, consisting of several ropes, is installed within the granular desulfurization chamber. The ropes' movement is adapted to the deflection base. When flue gas flow is low and the desulfurization slurry consumption on the adsorption sphere surface is low, the deflection base deflects accordingly. The downward deflection tightens the adjusting ropes, creating a flue within the adsorption sphere that guides the flue gas smoothly. As a result, the sulfur-containing flue gas passes through this flue, increasing the consumption of desulfurization slurry. Ultimately, this causes the deflection base to deflect in the opposite direction, thus actively and automatically adjusting the adsorption spheres within the granular desulfurization chamber for uniform desulfurization.

According to the effective treatment of special working conditions, a reasonable control strategy can be formulated, the pressure of a tunnel face is stably transited, settlement is strictly controlled, and the construction safety and the surrounding environment safety are guaranteed according to special application scenes such as complex composite stratum crossing and extremely close distance underneath crossing of existing buildings and structures and abnormal tunneling states such as shield starting, stopping and speed changing.
