FRP Spray Headers and Slurry Piping for FGD Systems
The FRP desulfurization spray layer is the core component of flue gas desulfurization systems in power plants, steel and chemical industries. It uses corrosion-resistant FRP pipes and achieves efficient coverage of desulfurization slurry through special nozzles. Its design is generally 3-6 layers with a spacing of 1.5-2.5 meters between layers. Spiral or hollow cone nozzles are used, combined with single-layer nozzles with a spacing of 0.7-1.2 meters, to ensure efficient desulfurization efficiency. Characteristics and design details of fiberglass desulfurization spray layer: Material characteristics: Fiberglass reinforced plastic (FRP) has excellent acid and alkali corrosion resistance, high temperature resistance, and lightweight and high-strength properties, making it particularly suitable for long-term flushing environments with desulfurization slurries. Structural layout: The distribution of spray layers should take into account both coverage and uniformity. Usually, a 3-6 layer design is used to achieve the best washing effect. Layer spacing and spacing: The layer spacing is controlled between 1.5-2.5 meters, and the spacing between single-layer nozzles is usually 0.7-1.2 meters to ensure sufficient contact between the flue gas and the slurry. Nozzle selection: use efficient hollow cone or spiral nozzle, spray angle is usually 90-120 degrees, which can maximize the slurry coverage area. Function: The entire system is responsible for spraying the slurry pressurized by the desulfurization pump into the flue gas, effectively absorbing sulfur dioxide, which is the core part of the desulfurization tower. Related applications also include various types of desulfurization towers, acid-base washing towers, waste gas treatment equipment, etc
