Stainless Steel Desulfurization Tower Equipment

      Stainless Steel Desulfurization Tower Equipment Product Introduction:

      What equipment is used for SO2 removal in industrial flue gas treatment? Answer: Desulfurization tower equipment is used to remove SO2 from flue gas, serving as the primary desulfurization device for boiler and kiln flue gas treatment. The materials of desulfurization towers include stainless steel, carbon steel, fiberglass reinforced plastic (FRP), and polypropylene (PP). Below is an introduction to the structural principles of stainless steel desulfurization tower equipment:

      Structure of Stainless Steel Desulfurization Tower Equipment

      The stainless steel desulfurization tower features an integrated structure with a cylindrical design. The equipment inside the desulfurization tower mainly includes agitators, oxidation air pipes, spray pipes, and demisters. Some designs also incorporate deflectors or distribution plates. The tower body is equipped with a dehydration device, and the rationally designed dehydration plates significantly prevent secondary water carryover, achieving a very high dehydration rate. Flue gas is naturally introduced from the lower part of the cylinder, featuring a large cross-section and low wind speed.

       Working Principle of Stainless Steel Desulfurization Tower Equipment:

      1. The flue gas generated by industrial boilers is first dedusted and then blown into the spray desulfurization tower by an induced draft fan under positive pressure (since the flue gas inlet is located in the middle of the desulfurization tower). At the entrance of the stainless steel desulfurization tower, a pre-cooling system reduces the temperature of the flue gas before it enters the desulfurization tower.

     2. The desulfurization tower is equipped with a three-layer atomization system. Inside the tower, SO2 in the flue gas fully reacts with the alkaline absorption liquid, removing sulfur dioxide through the reaction. The desulfurized liquid falls to the bottom of the tower, where the desulfurizing agent remains in a continuous循环 state.

      3. After multiple cycles, the desulfurization slurry is automatically discharged into the post-treatment system. The desulfurized flue gas utilizes the strong centrifugal force generated by its导向 effect to separate liquid droplets from the flue gas, achieving simultaneous dust removal and demisting. The filtered clean flue gas is ultimately discharged meeting standards.
