Flue gas baffle doors are widely used, mainly including the following aspects:
Thermal power plant: In the flue gas desulfurization system of coal-fired boiler, the flue gas baffle door controls the flow of flue gas by adjusting the opening degree of the baffle door, and realizes the adjustment of desulfurization effect.
Iron and steel smelter: In the blast furnace flue gas desulfurization system, the flue gas baffle door is used to control the opening and closing of the baffle door to realize the truncation and regulation of the flue gas.
Petrochemical plant: In the flue gas desulfurization unit, the flue gas baffle door realizes the regulation and control of flue gas by controlling the opening degree of the baffle door.
Chemical industry: In the flue gas desulfurization system of chemical plant, the flue gas baffle door regulates the flow of flue gas through the opening and closing of the baffle door, so as to realize the control of desulfurization effect.
Environmental protection industry: In the flue gas emission control of various pollution control equipment, the flue gas baffle door realizes the regulation and control of flue gas flow by controlling the opening and closing of the baffle door.
The principle of flue gas baffle door is mainly to control the direction and speed of gas flow in the flue system by opening and closing the baffle door. Inside the flue system, the speed and direction of gas flow is important for the efficiency and safety of combustion. If the gas flow rate is too high or the direction is incorrect, it will affect the combustion effect and the safety of the flue system.
Flue gas baffle doors usually adopt a single-axis driven double-louver baffle structure, and a sealed chamber for introducing sealed air is designed in the middle of double-layer blades. The sealing air continuously rushes into the cavity between the two layers of louvers and overflows from each sealing surface to shield the leakage of smoke gas and even achieve the effect of zero leakage.
In case of fire, the smoke baffle door also has the functions of smoke isolation and fire isolation. It can isolate the smoke in the area where the fire occurs, avoid the further spread of the smoke, and at the same time prevent the fire from spreading to other areas.
Generally speaking, the flue gas baffle door plays an important role in industrial production, which can effectively control the flow and emission of flue gas, and ensure the normal production and environmental safety.
