Description
Technical field
The utility model belongs to a kind of equipment that is used for firepower electricity power plant desulphurization system,
Background technology
Baffle door is mainly used in the desulphurization system of thermal power plant flue.In the prior art, the blade of twin shaft twayblade shutter type desulfuration baffle door is as a whole, has only forward and backward diaxon.Distortion when the flue width can produce blade during greater than 7000 meters causes baffle door to be not closed completely, and does not have the effect of sealing fully.The framework side plate directly produces stress deformation with the framework welding makes diaphragm seal that the smooth wind leakage that causes sealing can't be installed.Can't weld between front and back axle head and the frame seal side plate, preset clearance can't guarantee again, cause baffle plate bore seal wind too much to be revealed, and the flue internal pressure increases in the big capacity unit operation, and baffle door stops baffle door to leak because of above design defect can't guarantee the sealing wind that is higher than flue gas pressures.
Summary of the invention
The purpose of this utility model is to design a kind of tandem three axle bed twayblade shutter type desulfuration baffle doors, with the distortion that solves the long generation of blade make that baffle door is not closed completely, diaphragm seal can't install and smoothly cause sealing between wind leakage, axle head and the frame seal side plate and can't weld, preset clearance can't guarantee, make baffle plate bore seal wind too much defective such as leakage can reach 100% sealing effectiveness to guarantee whole baffle door.
The technical scheme that provides according to the utility model, the rotating shaft of the some lateral arrangement that are parallel to each other is installed on framework equably, the blade that can rotate around the axis is installed in every rotating shaft, it is characterized in that: each root rotating shaft has three parts, be respectively the front axle that is installed on frame left, the rear axle that is installed on frame right, and be installed on jackshaft in the middle of the framework, and front axle, rear axle and jackshaft all are positioned on the same axis, and blade is being installed respectively between front axle on the same axis and the jackshaft and between jackshaft and the rear axle.
Be positioned at front axle or rear axle on a section of the framework outside crank is installed, utilize connecting rod to be hinged between adjacent two cranks.Blade has top panel and the lower panel of arranging that be parallel to each other to be formed by connecting, around blade, form special-shaped groove, edge at special-shaped groove connects diaphragm seal, corresponding position on framework is provided with side plate, when blade is in closed condition, the outer end of diaphragm seal is attached on the side plate, forms the cavity of sealing, and the import of sealing air is set on side plate.
Pressure-measuring pipe and close air intake butterfly valve are set in the upper end of framework, blow-off pipe are set, be used to drive the electric operator that crank rotates around the axis in the frame facet installation in the lower end of framework.Between rotating shaft and framework, alloy sleeve is set; Joint portion at rotating shaft and framework is provided with sealing device.
Advantage of the present utility model is the overlength blade is decomposed into short relatively blade, the overall dimensions of baffle door is constant, strengthened the bulk strength of baffle door when satisfying the flue design again, the baffle door torque that minimizing causes because of blade is long is excessive, deformable blade, poorly sealed defective, also improved simultaneously the design of frame seal side plate, change former straight plate and framework welding into the bending welding, reduce the flatness of the heavily stressed distortion enhanced leaktightness sheet of welding, further improve the design rationalization of desulfuration baffle door, satisfy the desulfurization needs of big unit.
