Smoke barrier door
1、Overview of smoke baffle door products:
The flue gas damper door is produced and manufactured by Lianyungang Huaneng Power Auxiliary Equipment Co., Ltd. with imported technology. It is used on the inlet, outlet or bypass flue of the flue gas system absorption tower, or in flue gas denitrification and dust removal systems. The flue gas damper door usually adopts a louver type double-layer damper structure. When closed, sealed air is introduced between the double-layer dampers for gas sealing, achieving the function of isolating and shutting off the flue gas.
The sealing material of the smoke baffle door is made of specially treated alloy sheets, which have stronger elasticity and self-cleaning function. The passive enhanced sealing structure fully ensures that the gap between the sealing sheets is minimized, which can effectively ensure zero leakage of the equipment for a long time. Assist in the design of the quick opening mechanism to reduce the starting torque, making the quick opening device safer and more reliable. A reliable welding process can ensure that the weld seam has the same anti-corrosion life as the material body. The mechanical linkage control of the air seal valve is safe and reliable.
2、 Technical parameters of smoke baffle door:
1. Flue section: W (width) x H (height) x L (thickness);
2. Applicable medium: cold and hot flue gas;
3. Design temperature resistance: ≤ 350 ℃;
4. Design pressure: ± 8500Pa;
5. Leakage rate of smoke inside and outside: "0"
6. Drive mode: electric or pneumatic;
7. Power and control requirements: to be selected by the user.
3、 Performance characteristics of smoke baffle door:
1. The smoke baffle door adopts a single axis driven double louver baffle structure, with a sealed chamber designed in the middle of the double-layer blades to introduce sealed air. The sealed air above the smoke pressure is introduced into the baffle, forming a sealed air isolation layer between the double-layer baffles to block the passage of smoke flow.
2. The opening and closing time of the smoke baffle door is ≤ 60 seconds (can be selected according to user requirements).
3. The external design has a connecting rod mechanism that allows several blades to open or close synchronously. The shaft seal device is separated from the rolling bearings, making it easy to adjust and maintain without bearing corrosion concerns.
4. The design structure of the double louvered smoke barrier door is reasonable, with good blade rigidity and stable and reliable operation. The sealing type of the louvered barrier blade is elastic seal or gas seal.
5. The smoke baffle door can be driven in multiple ways: electric or pneumatic.
6. The air seal fan and door panel are controlled by a mechanical linkage mechanism, which is safe and reliable.
4、 Scope of supply for smoke baffle doors:
Including the damper body, sealed air inlet valve, driving device (electric or pneumatic device) and other accessories, the sealed fan can be supplied as a complete set.
5、 Common specifications and models:
6、 Ordering instructions for smoke baffle doors:
1. Provide the size of the flue interface in mm × mm.
2. Installation direction of pipeline: width mm, height mm, thickness mm;
