The common type of desulphurization Damper door is Louve Window Damper, which can be divided into two forms: Single Louver Damper or Double Louver Damper. Single baffle also gives single blade and double blade construction. Generally, the single baffle double blade structure and double pin plate door structure should be equipped with a sealed air system, connected to zero leakage design, single baffle door, no need to install a sealed air system, design sealing efficiency of about 90% to 99.5%. In the double blade hundred elbow window baffle door used more.

1. the use of single-shaft drive double louver window baffle structure, the middle of the double layer is designed to import sealed air sealing chamber, will be higher than the flue gas pressure 500Pa of sealed air into the baffle, the formation of sealed air isolation layer between the double layer baffle, block the smoke flow through.

2. air door opening and closing time ≤60S (can be selected according to user requirements).

3. Connecting rod mechanism is designed to open or close several blades synchronously.

4. The design of double shutter baffle door is reasonable. The time plate has good rigidity, and the operation is stable and reliable.

5. The double baffle is designed and installed with a sealed air inlet valve. After entering the sealed air, the sealing efficiency of the rice door is 100%.

6. drive mode: pneumatic or electric.

7. the driving device usually adopts direct connection with the air valve installation.

8. electric device adopts electromechanical integration products, with torque protection and limit device and remote control operation, electric device also has a hand, electric switch function for installation, debugging, maintenance.

9. Connection mode of air damper and pipe: flange sealing welding connection or flange bolt connection.

10. The sealed fan and electric heater of the sealed air system can be provided by our company after selection.
