Baffle door is mainly used in flue gas desulfurization system absorption tower inlet, outlet or bypass flue gas, or in flue gas denitrification and flue gas dust removal system. Wind door baffle usually adopts louver double-layer baffle structure. Wind door adopts special sealing device, which has good sealing performance. Wind leakage rate of blower tube muffler safety valve muffler is less than 0.1%. The actuator can be operated by electric or pneumatic mode, and can be operated in long and short distance. The opening and closing time can be set according to the need. Electric device adopts Mechatronics products. Small hole muffler of exhaust muffler has moment protection and limit device and can be operated remotely. Electric device also has hand and electric switching function for installation, commissioning and overhaul. The pneumatic device adopts proximity switch to make the door plate open completely and stop automatically in the closed position, and adopts locking device and reasonable logic circuit to make the locking device open when the valve is opened, and the locking device of the steam muffler when the valve is closed, so as to ensure the safe and reliable operation of the pneumatic valve.
Performance characteristics of baffle door
1. Flexible switch, no jamming phenomenon and low resistance in normal operation.
2. After closing, there are no internal leakage, external leakage, good sealing, no air leakage and air leakage.
3. Open-close signal is connected with DCS to achieve on-line monitoring.
4. Simple operation, short installation period, can be completed in the minor repair period.
5. Long service life, a basic installation without maintenance.
6. It is driven by a new hydraulic way with high stability.
7. High temperature does not deform and does not collect soot.
8. Flange bolt smoke is used to connect with the passage, which is convenient for installation and disassembly.
9. The manufacturing process meets the relevant industry standards.
10. Use special sealing material, patent technology sealing, good sealing performance, high wear resistance.
