Principle of desulfurization tower

After dust removal, the flue gas generated by the boiler is blown into the spray desulfurization tower under positive pressure by the induced draft fan (the flue gas inlet is set in the middle of the desulfurization tower). A pre cooling system is installed at the inlet of the desulfurization tower, and the cooled flue gas enters the desulfurization tower. Set up a three-layer atomization system inside the tower, where the space in this section is filled with particles with a diameter of 100-300 sprayed by the atomizer μ The atomized droplets of m fully react with the absorbed alkali solution to remove sulfur dioxide in the flue gas. The desulfurized liquid falls into the bottom of the desulfurizing tower, and is regularly discharged into the collection system set behind the desulfurizing tower. After a certain amount of alkali liquor is properly supplemented, it is sent to the spray and liquid preparation system through the circulating pump for reuse. The desulfurizing agent is always in circulation.

After multiple cycles, the desulfurization slurry is discharged into the post-treatment system. When the desulfurization flue gas passes through the tower top mist eliminator, its guiding effect generates strong centrifugal force to separate the liquid droplets in the flue gas, achieving the effect of simultaneous dust removal and mist removal. Clean flue gas emissions meet the final standards.
