Description

The flue gas desulfurization baffle door

Technical field

The utility model relates to the flue gas desulfurization device field, relates in particular to the flue gas desulfurization baffle door.

Background technology

In large-scale thermal power industry, metallurgy industry, often there is a large amount of sulfur-containing smoke gas to discharge, sulfur-containing smoke gas can cause the pollution to atmosphere, forms acid rain.At present, discharging again after flue gas desulfurization unit commonly used is handled sulfur-containing smoke gas, but when unit breaks down, need to prevent that sulfur-containing smoke gas from leaking, or make flue gas enter other flue gas desulfurization unit by flue with flue gas desulfurization baffle door blocking-up fume emission.Maximization along with flue gas desulfurization device, the existing flue gas desulfurization baffle door pair blinds single shaft baffle doors that adopt more, as depicted in figs. 1 and 2, this kind flue gas desulfurization baffle door comprises framework 1, is installed in sealing air-valve 5 on the framework 1, organizes the rotating shaft 31 of blade 3 and supporting blade 3 more.Charge into air by sealing air-valve 5 to the inner chamber 33 of blade 3 when blade 3 is closed, in baffle door, form air curtain, thus the circulation of blocking-up flue gas.In the flue gas desulfurization baffle door of this kind structure, the two ends of rotating shaft 31 are supported on the framework 1 by bearing, because the axial dimension of rotating shaft 31 is longer, rotating shaft 31 middle parts must be supported on the central sill 11 by bearing, be equiped with two fan leafs 3 in the every rotating shaft 31, lay respectively at central sill 11 both sides, the accuracy of manufacture of parts such as this structure countershaft 31 and bearing requires high, manufacture difficulty is big, to the matching requirements height, the Installation and Debugging difficulty, and after baffle door is installed to flue, break down as rotating shaft 31 or intermediate bearing, then can't keep in repair.

The utility model content

The technical problems to be solved in the utility model is to overcome the deficiencies in the prior art, provide a kind of easily manufactured, dismounting simple, be convenient to keep in repair, the flue gas desulfurization baffle door of good sealing effect, reasonable price.

For solving the problems of the technologies described above, the technical scheme that the utility model proposes is: a kind of flue gas desulfurization baffle door, comprise framework, toggle, YE, sealing air-valve and two groups of blades that are installed on the framework, framework central authorities are provided with central sill, two groups of blades lay respectively at the central sill both sides, toggle is installed on the curb girder of framework and with rotating shaft of each group blade and links to each other, the input of toggle links to each other with YE, the sealing air-valve is installed on the framework, described central sill is provided with two groups and is vertical tandem rotating shaft installing hole, rotating shaft one end of each blade is installed on the curb girder, the other end is installed in the rotating shaft installing hole of central sill, and two groups of blades form vertical front and back and arrange.

Described toggle links to each other with the on-off switch of sealing air-valve.

The periphery of described blade is equiped with elastic sealing strip.

Compared with prior art, advantage of the present utility model just is: two groups of blades of flue gas desulfurization baffle door are vertical front and back and arrange, each fan leaf passes through a shaft support respectively between central sill and curb girder, this structure requires low to the accuracy of manufacture of parts such as blade, rotating shaft, manufacture difficulty is little, Installation and Debugging, assembly and disassembly are simpler, are convenient to maintenance and check; Toggle links to each other with the on-off switch of sealing air-valve, when YE driving toggle is closed blade, the on-off switch of sealing air-valve produces interlock, the sealing air-valve is opened thereupon, in blade, charge into air, sulfur-containing smoke gas is blocked rapidly, and when baffle door was opened, the sealing air-valve can cut out thereupon; The periphery of blade is equiped with elastic sealing strip, and after charging into air in the blade, the elastic sealing strip on the adjacent blades closely forces together, and forms double-layer seal, reaches more excellent sealing effectiveness; Flue gas desulfurization baffle door of the present utility model has been because reduced accuracy of manufacture requirement, simplified the Installation and Debugging process, thereby reduced production cost, and product price is more cheap.

The specific embodiment

As Fig. 3, Fig. 4 and shown in Figure 5, flue gas desulfurization baffle door of the present utility model, comprise framework 1, toggle 2, YE 4, sealing air-valve 5 and two groups of blades 3 that are installed on the framework 1, framework 1 central authorities are provided with central sill 11, two groups of blades 3 lay respectively at central sill 11 both sides, two set of bell cranks linkages 2 are installed in respectively on two curb girders 12 of framework 1 and with rotating shaft 31 of each group blade 3 and link to each other, the input of each toggle 2 links to each other with a YE 4, sealing air-valve 5 is installed on the framework 1 and by framework 1 and is communicated with the inner chamber of blade 3, central sill 11 is provided with two groups and is vertical tandem rotating shaft installing hole 111, rotating shaft 31 1 ends of each blade 3 are installed on the curb girder 12, the other end is installed in the rotating shaft installing hole 111 of central sill 11, and two groups of blades 3 are arranged before and after forming vertically.Each rotating shaft 31 is supported on the framework 1 by bearing.The accuracy of manufacture of parts such as this structure countershaft 31 and bearing requires low, and manufacture difficulty is little, and Installation and Debugging, assembly and disassembly are simpler, is convenient to maintenance and checks.Toggle 2 links to each other with the on-off switch 51 of sealing air-valve 5.When YE 4 driving toggles 2 were closed blade 3, the on-off switch 51 of sealing air-valve 5 produced interlock, and sealing air-valve 5 is opened thereupon, inner chamber 33 to blade 3 charges into air, blocking-up sulfur-containing smoke gas circulation rapidly, when blade 3 was opened, sealing air-valve 5 can cut out thereupon.As shown in Figure 6, the periphery of blade 3 is equiped with elastic sealing strip 32, and after charging into air in the blade 3, the elastic sealing strip 32 on the adjacent blades 3 closely forces together, and forms double-layer seal, reaches more excellent sealing effectiveness; Flue gas desulfurization baffle door of the present utility model has been because reduced accuracy of manufacture requirement, simplified the Installation and Debugging process, thereby reduced production cost, and product price is more cheap.
