Flue Gas Desulphurizing Baffle Damper

Product description

Flue gas desulfurization double louver damper baffle the introduction of foreign advanced technology production, the desulfurization absorption tower damper used in flue gas desulfurization system on the import and export or bypass flue, or used for flue gas denitration and flue gas dust removal system, the damper usually adopts the louver double panel structure, shut off when the double pass into the sealing between baffle, the effect of isolation shut off the gas.

1. This damper is easy to corrode due to sulfur dioxide contained in the air duct. It is designed and made with Q235 outsourcing 316L material, which has features of temperature resistance, corrosion resistance and long service life.

2. In order to make the damper door plate hard to be deformed at high temperature, there are reinforcing bars between the double-layer plates. The thickness of the single-layer plate is 5mm, and the total thickness of the damper is 600mm. The wind door shaft head, axle bush, axle sleeve and shaft are made of several kinds of high temperature, wear-resisting and corrosion-resistant materials respectively.

3. The electric device is connected with the valve shaft, without clearance, and the air leakage rate after closing is less than 0.1%.

4. The electric device is equipped with a limit multi-function device, and the switch is in place accurately.

5. The distribution cabinet is equipped with DCS interface to achieve automatic operation effect.

6. With adjustment, isolation and sharing, flexible adjustment and good isolation performance.

7. Flexible switch, no jam phenomenon, no internal leakage, external leakage phenomenon, good shaft sealing.

8. High degree of full automation, with remote, close and manual operation functions.

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.
