Product description

The flue gas desulfurization double-layer shutter-type baffle door produced by our company is based on the introduction of foreign advanced technology and adopts optimized structural design. The equipment works reliably under operating conditions, with flexible opening and closing, tight shut-off, high strength, good rigidity, and sturdiness, which greatly improves the desulfurization efficiency of the system and meets the environmental protection requirements for exhaust gas. Our company is a professional manufacturer of power damper equipment for thermal power plants, and has been widely used in major thermal power plants.

Structure

1. The flue gas desulfurization double louver type baffle door adopts a single-axis drive double louver type baffle structure. The middle of the double-layer blades is designed with a sealed chamber for introducing sealed air, and the sealed air at least 500Pa higher than the flue gas pressure is passed into the baffle. A sealed air insulation layer is formed between the double-layer baffles to block the flow of smoke.

2. Flue gas desulfurization double shutter-type baffle door opening and closing time ≤ 60S (can be selected according to user requirements).

3． The flue gas desulfurization double-layer shutter-type baffle door housing is designed with a connecting rod mechanism. After optimized design, the shutters of the baffle are opened and closed in a louver streamlined manner, and the opening and closing are synchronized to achieve integrated operation.

4． Flue gas desulfurization double louver type baffle door has reasonable design structure, good blade rigidity, stable and reliable operation, flue gas desulfurization double louver type baffle door blade seal type: elastic seal and gas seal, and a sealed air inlet is designed and installed on the casing Valve, interlocking control with flapper door. After sealing air with a certain pressure and flow is passed between the blades, it can effectively isolate the front and rear smoke airflow, so that the sealing efficiency of the baffle door is 100%.

5. The flue gas desulfurization double-layer shutter-type baffle door can rotate flexibly under the working conditions without jamming. Adopting a seat-type (high-temperature resistant) self-aligning bearing structure with a seat, the driving torque of the baffle is smaller, and the rotation is more flexible and lightweight. The baffle blade is designed with thermal expansion compensation gap, which is safe and reliable under hot state operation.

6. The flue gas desulfurization double louver type baffle door baffle is designed as a streamlined structure, which can fully reduce the resistance to the air flow. The outer frame of the door is made of profiled steel, and the blade design adopts an airfoil (or flat plate) structure, which makes the airflow distribution reasonable and smooth. The blade body is made of ordinary carbon steel or alloy steel, and the overlap (or sealed with the shell) of the blade is a flexible stainless steel or nickel-based alloy steel seal, which has the strength and rigidity in accordance with the working conditions and is firm. Attached to the extension shaft. The shaft shank device of each damper blade is supported by two externally mounted, self-leveling, and maintenance-free flanged bearings, which effectively avoids the increase in driving torque caused by the misalignment of the front and rear shafts of the baffle or the blade opening and closing after long-term operation Occurrence of jamming.

7. The current smoke connection method of the flue gas desulfurization double-layer louvered baffle door is that the flue is inserted into the flange of the baffle door and the flange is sealed and welded. Due to anti-corrosion requirements, the baffle door with lining is sealed and welded at the front and back flanges after being hoisted on site. The lining must be sealed and welded. The on-site anti-corrosion layer must cover the shell lining.

8. The flue gas desulfurization double-louver shutter door is generally driven by electric or pneumatic. Convenient and reliable control. It can input and output digital signals (or input and output analog signals) to control the blade opening degree and reflect the blade opening state in real time according to the requirements of the system operating mechanism. It can be operated remotely or controlled by programs, which is convenient for DCS control automation.

9. The flue gas desulfurization double-layer shutter-type baffle door electric (pneumatic) actuator adopts intelligent integrated control, has torque protection and limit switch, can control operation locally or remotely, and also has hand, electric (pneumatic) dynamic switching function In preparation for installation, commissioning and maintenance. After installation and commissioning, it leaves the factory. Before leaving the factory, the limit switch of the electric (pneumatic) device has been adjusted and set in place. The user only needs to plug in the power supply (or air source) and connect it to the terminal to make the baffle door work normally.

10． The sealed fan and electric heater of the sealed air system can be provided as a set after our selection.
