Smoke damper door
The flue gas damper is mainly used on the inlet, outlet or bypass flue of the absorption tower in the flue gas desulfurization system, or in the flue gas denitrification and dust removal system. The damper is usually a double-layer shutter structure with a special sealing device. The sealing performance is good, and the air leakage rate of the blow pipe muffler safety valve muffler is ≤ 0.1%. The executing mechanism can be electric or pneumatic, and can be operated from a distance. The opening and closing times can be set as needed. The electric device adopts mechatronics integrated products. The exhaust muffler small hole muffler has torque protection and limit device, and can be remotely controlled and operated. The electric device also has manual and electric switching functions for use during installation, debugging, and maintenance. The pneumatic device adopts a proximity switch to automatically stop the door panel in the fully open and fully closed positions, and adopts a locking device and a reasonable logic circuit to open the locking device when the air door is opened, and lock the locking device when the steam muffler air door is closed, fully ensuring the safe and reliable operation of the pneumatic air door.
