Product Introduction of Boiler Flue Gas SDS Sodium-Based Dry Desulfurization Equipment

       Boiler flue gas desulfurization refers to the treatment of SO2 in boiler flue gas. The main desulfurization processes for boiler flue gas include dry desulfurization and wet desulfurization. Our company has developed a complete set of SDS dry desulfurization equipment with sodium bicarbonate ultrafine powder injection modules specifically for the treatment of flue gas from small boilers and small kilns. The SDS sodium-based dry desulfurization equipment system mainly includes: pneumatic feeder, sodium bicarbonate ultrafine powder silo, arch-breaking discharger, screw metering and conveying injection module, high-pressure ring blower, pipeline system, control system, etc.

      The principle of the boiler flue gas SDS sodium-based dry desulfurization process involves the thorough mixing and close contact of the ultrafine powder desulfurizer with the boiler flue gas. With the combined action of configured catalysts and promoters, it rapidly reacts with SO2 in the boiler flue gas.The SDS sodium-based dry desulfurization process system is relatively simple, with reliable and durable equipment performance,small equipment footprint, flexible layout, andhigh desulfurization efficiency, easily meeting current special emission limit requirements.

      Boiler flue gas SDS sodium-based dry desulfurization equipment.The SDS dry acid removal injection technology mainly involves uniformly injecting the desulfurizer—sodium bicarbonate ultrafine powder (particle size 20–30 μm)—into the pipeline (using the flue as the desulfurization reactor under small flue gas volume conditions). The flue gas desulfurizer is thermally activated in the pipeline, rapidly increasing its specific surface area and fully contacting the acidic flue gas SO2, leading to a series of physical and chemical reactions. Acidic substances such as SO2 in the boiler flue gas are absorbed and purified.
