    Bypass Flue Gas Desulfurization Baffle Door Easy Operate Steel Body Material

    bypass desulfurization baffle door


    Product description


    In the case of normal operation of the desulfurization system, flue gas from the boiler tail electrostatic precipitators, the flue gas desulfurization system after entry barrier gate to booster fan, again by flue gas heat exchanger cooling into the absorption tower, after desulfurization of flue gas was heated to a temperature of about 80 ℃, flue gas heat exchanger by export desulfurization baffle door into the chimney flue gas desulfurization system.


    The flue gas desulfurization system is provided with bypass flue gas, which is equipped with bypass baffle door. When the flue gas desulfurization system is repaired, maintained or the flue gas working condition is abnormal, the flue gas is discharged directly into the chimney through the bypass flue gas to ensure the safety of the desulfurization system.The isolation and connection between the power station and the desulfurization island is realized by opening and closing the desulfurization baffle door in the flue gas system.


    Importance of bypass desulfurization baffle door setting


    1. If the bypass flue bypass flue gas damper, not in the actual operation must be the side of the import and export of flue gas desulfurization system of flue gas pressure difference to adjust for "zero", in order to guarantee the whole flue gas desulfurization of flue gas desulfurization system, and always maintain this state in the flue gas desulfurization system operation without deviation, control is difficult, especially the flue gas condition change, this is a normal phenomenon control harder to achieve.


    2. If the flue gas desulfurization system is not equipped with bypass flue gas baffle, in the actual operation, part of the net flue gas may be re-inhaled into the flue gas desulfurization system system or the original flue gas directly discharged into the chimney.If the flue gas desulfurization system does not have high requirements on desulfurization efficiency (such as some domestic power stations), bypass baffle can be removed, but for flue gas desulfurization system with high requirements on desulfurization efficiency, the installation of bypass baffle is very important.


    3. If there is no bypass baffle in the flue gas desulfurization system, a certain margin should be considered when selecting the booster fan capacity, so the cost and operation cost of the booster fan will increase a lot.


    Type and application of FGD baffle doors in flue gas desulfurization system


    At present, the desulfurization baffle doors used in the flue gas desulfurization system of large and medium-sized power plant boiler units mainly include single-shaft double louver baffle doors, double-shaft double louver baffle doors, single-shaft double seal baffle doors and other types.The single - axis double - louver baffle door and double - axis double - louver baffle door more applications.


    1. Single-axle double louver baffle door

    The type of baffle door consists of a shutter consisting of two blades, which is provided with a sealed air system that allows sealed air to enter between the blades.The biggest advantage of this kind of desulphurization baffle door is its sealing piece has self-cleaning function, the weight of baffle door is only about half of double axle double louver baffle door, investment cost is also compared to double hundred leaf window baffle door save 50%.The strength of the single-shaft double-louver baffle gate is slightly lower than that of the double-shaft double-louver baffle gate.


    2. Double-axle double louver baffle door

    The type of baffle door consists of two shutters, each connected to a number of bearings, two blades fixed on the same shaft.The sealing plate of the baffle door is installed around the baffle door blade with a special base alloy, and the sealing air system is arranged, and the sealed air enters between the two shutters.The current design of biaxial double louver baffle door sealing gas system can ensure zero leakage rate of flue, and in the case of system load with accident prevention measures.This kind of baffle door has a large investment, and its weight and size are much larger than that of single-shaft double-louver baffle door.


    3. Single shaft double seal baffle door

    This type of baffle door consists of a shutter with only one blade for each shutter. Two seals are arranged between the upper and lower blades and between the blades and the frame. The sealing air can be poured into the sealing frame by the seals.The weight and investment of single shaft double seal baffle door are less than double shaft double louver baffle door, along the flow direction of the medium is also slightly shorter than the latter.
