Abstract
The utility model relates to a monolayer blade dual-sealing baffle door. The monolayer blade dual-sealing baffle door comprises a frame and blades; the blades are arranged inside the frame by a shaft; the blades and the shaft are in fixed and tight connection; a frame inside peripheral sealed air chamber body is arranged on the frame; a blade sealed air chamber body and a surface contact sealed sheet are respectively arranged on the blades at two sides of the shaft; an air valve is arranged on the frame and is fixed with the frame; and the air valve is respectively communicated with the frame inside peripheral sealed air chamber body and the blade sealed air chamber body. Each blade has a monolayer structure; a deformation adjusting device consisting of reinforcing ribs and adjusting bolts is arranged on the blades. As the monolayer blade is adopted, the monolayer blade dual-sealing baffle door reduces raw material for preparing the baffle door, simplifies the manufacturing process, reduces production cost, increases the reliability of closing the baffle door and reduces the sealed air input. The monolayer blade dual-sealing baffle door has the advantages of reasonable design, simple structure, convenient use, good sealing performances, isolation and fume conduction and reduction of raw material consumption and production cost.
Description
Technical field
The utility model relates in a kind of power plant, desulphurization system and other industrial system in flue isolated or admittance flue gas and can regulate the device of flue gas flow, is specifically related to a kind of individual layer blade double containment baffle door.
Background technology
Baffle door is a very important equipment in the desulphurization system, in order to protection desulphurization system and safe operation of the boiler, and for the repair and maintenance of desulphurization system provides suitable working environment, is the main means of desulphurization system and boiler off-the-line.Be divided into former flue gas, clean flue gas and by-pass damper door according to purposes, play effect isolated and the admittance flue gas.
Therefore desulfurization retaining door is relatively stricter to seal request, and the slip of all baffle doors all should be designed to 0%, and must consider the distortion that inevitably causes owing to thermal (temperature difference) stress in service.
The subject matter that existing baffle door exists is, poor sealing performance, and easy deformation in the use, and also the baffle door raw materials consumption is big, and production cost is too high.
Summary of the invention
For overcoming the deficiencies in the prior art, the utility model provide a kind of reasonable in design, simple in structure, easy to use, sealing is isolated and admittance flue gas performance is good, the individual layer blade double containment baffle door that reduces raw materials consumption, reduce production costs.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of individual layer blade double containment baffle door comprises framework and blade, blade pass cross the axle be installed in the framework, blade with spool between fixing compact be connected; Framework is provided with sealing air cavity around the framework inboard, is respectively equipped with runner sealing air cavity on the blade on axle both sides and contacts diaphragm seal with face; Framework is provided with air valve, and air valve is connected with frame fixation, and air valve is communicated with sealing air cavity and runner sealing air cavity around the framework inboard respectively.
Described blade is a single layer structure, and blade is provided with by reinforcement and and regulates the deformation adjustment device that bolt constitutes.
The utility model at work, sealing air is by sealing air cavity and runner sealing air cavity around the framework, the sealing air cavity compresses whole sealing baffle door around making framework, runner sealing air cavity compresses the face contact diaphragm seal on the blade, stop boiler smoke to leak into opposite side, realize the zero leakage of boiler smoke from a side of baffle door.
The beneficial effects of the utility model are, owing to adopt the individual layer blade, have reduced the raw material of making baffle door, have simplified manufacturing process, have reduced production cost.The sealed channel volume that forms by face contact diaphragm seal is than little many of double-deck baffle door, also little many of required sealing air amount, and the optional littler power of seal fan has significantly reduced operating cost.The distortion that baffle door is in operation and produces after the adjusting device adjusting, has recovered the sealing of face contact diaphragm seal, has increased the reliability that baffle door is closed, and has also reduced the sealing air quantity.
The utlity model has reasonable in design, simple in structure, easy to use, sealing is isolated and admittance flue gas performance is good, the advantage that reduces raw materials consumption, reduce production costs.
