Stainless Steel Duct Isolation Dampers , Flue Gas Desulphurizing Baffle Damper

Flue Gas Desulphurizing Baffle Damper

Product description

Flue gas baffle door is mainly used for flue gas desulfurization system absorption tower inlet, outlet or bypass flue gas flue, or for flue gas denitrification and flue gas dust removal system, damper baffle usually adopts louver type double-layer baffle structure, damper adopts special sealing device, good sealing performance, blowing tube muffler safety valve muffler leakage rate ≤0.1%.The actuator can be operated by electric or pneumatic means. It can be operated near and far. The opening and closing time can be set as required.The electric device adopts mechatronic products. The exhaust muffler has a small hole muffler with torque protection and limit device and can be operated remotely. The electric device also has a manual and electric switching function for installation, debugging and maintenance.The pneumatic device adopts the proximity switch to make the door stop automatically at the position of full open and full closed, and adopts the locking device and reasonable logic circuit to make the locking device open when the damper is opened and the locking device lock when the steam silencer damper is closed, completely ensuring the safe and reliable operation of the pneumatic damper.

Performance characteristics of flue gas baffle door

1.When working normally, switch is flexible, without jam, low resistance.

2.After closing, no internal leakage, external leakage, good sealing, no leakage, air leakage phenomenon.

3.Open and close signal is connected with DCS to achieve online monitoring.

4.Easy operation, short installation cycle, can be completed in minor repair period.

5.Long service life, a basic installation without maintenance.

6.Adopt new hydraulic drive, high stability.

7.High temperature does not deform, do not collect soot.

8.Flange bolt smoke and connection, easy to install and dismantle.

9. The production process conforms to relevant industry standards.

10. Adopt special sealing material and patented technology for sealing, good sealing performance and high abrasion resistance.

Technical parameters

1. Flue section: D (width) * W (height) * L (thickness);

2. Applicable medium: cold and hot flue gas;

3, the design of heat-resistant: 300 ℃ or less;

4. Design pressure:

5. Internal and external leakage rate of flue gas: "0"

6. Drive mode: electric or pneumatic

7. Power supply and control requirements: user selection.

Advantages

1. Fewer blades, load-bearing parts and moving parts. Baffle door has anti-torsion performance, adopts rigid design and can be connected flexibly.

2. Blade edge length is greatly reduced (about 50%), and adjustable sealing device is adopted to make it have better sealing performance and achieve zero leakage.

3. The sealing part has no friction load, so it can be better sealed for a long time.

4. Because baffle door adopts streamline design, the pressure loss is less.

5. Low noise.
