Double-sealed damper doors are based on the introduction of foreign technology and the adoption of an optimized layout scheme. The product features easy opening and closing with机动 rotation, reasonable driving torque, reliable closure precision, and a long service life. It is a critical auxiliary equipment in the desulfurization system of power plants. Double-sealed damper doors are used for the continuous intake and outlet or bypass flue gas channels in the flue gas desulfurization system, or for enhancing flue gas denitrification and dust removal operations. The doors generally adopt a double-layer blade structure, with double blades maintaining a sealed air gap when closed, achieving the effect of isolating and shutting off flue gas in China. The product operates reliably, responds quickly to开关 commands, has high strength, good rigidity, and durability, significantly enhancing the desulfurization efficiency of the system and meeting the environmental protection requirements for flue gas desulfurization. Technical Parameters of Double-sealed Damper Doors: 1. Double-sealed damper doors are specified by DSD (type) - W (width) × H (height). 2. Power supply: AC three-phase three-wire ~ 380V/50Hz or as determined by the user. Air source: Compressed air 0.4MPa-0.8MPa. 3. Leakage rate: ≤0%. 4. Temperature resistance: <350°C, for temperatures above 350°C, please specify separately (high-temperature service through the damper signal can reach 1100°C). 5. Wind pressure: As usual <26000Pa, for large-scale closed damper doors or special requirements, please specify separately. 6. Flowing working medium: Flue gas or other dusty gases.
