Abstract
The utility model discloses a double-blade shutter type baffle board door of a flue, which comprises a door frame, an inner-side anticorrosive coat, a plurality of blades which are horizontally arranged in the door frame by a rotating shaft from top to down, and a rotating shaft-driving mechanism which is arranged at the outer side of the door frame, wherein each blade is an interlayer structure formed by two rectangular boards; the upper edges and the lower edges of the two rectangular boards are respectively provided with an anticorrosive elastic sealing strip; a top beam of the door frame is provided with an air inlet which is communicated with the inner cavity of the interlayer of each blade and an turning on/off valve which controls the sealing air to pass; and a plurality of rotating shafts of the blades at the top in the door frame are hinged with a crankshaft of the valve by a connecting rod. The double-blade shutter type baffle board door has the advantages that an air-tight air control valve is turned on by the rotating shafts of the blades at the top in the door frame through a connecting rod of the crankshaft, and the gas with larger pressure compared with the pressure of the smoke in the flue is transmitted into the inner cavity of the interlayer of each blade by an external air source to play a part in air-tight sealing when the blades of the baffle board door are turned off; and the air-tight air control valve is turned off when the blades of the baffle board door are turned on.
Description
Technical field
The utility model relates to the damper door, especially relates to twayblade venetian blind type damper door.
Background technology
The sulfur method that generally adopts at present both at home and abroad aspect thermal power plant's flue desulfurization generally is divided into desulfurization three major types after desulfurization in desulfurization before the burning, the burning, the burning.The desulfurization of the full wet flue gas body of limestone-gypsum is a desulfurization method after the burning of the unique large-scale commercial applications application in the present world, and the domestic and international heat-engine plant desulfurized technology more than 90% all adopts the full wet desulphurization technology of limestone-gypsum.Baffle door is to break down as flue gas desulfur device maybe must shut down when safeguarding, boiler smoke via the flue bypass to smoke stack emission, control flue collector and the sealing of bypass flue or open the special valve of usefulness.Existing baffle door structure adopts venetian blind type damper door more, and the edge of adjacent blades overlaps mutually; The deficiency of its existence is because blade is single blade, and closed condition adjacent blades lap-joint be hard contact, certainly will exist to be out of shape to be not closed completely and to cause air leakage phenomena.
Summary of the invention
The utility model purpose is to provide a kind of corrosion-resistant, leak free twayblade venetian blind type damper door.
For achieving the above object, the utility model can be taked following technical proposals:
Twayblade venetian blind type damper door described in the utility model, it comprises doorframe, is horizontally set on a plurality of blades in the described doorframe by rotating shaft from top to bottom, and the rotating shaft driving mechanism that is arranged on the doorframe outside; The sandwich of described blade for constituting by two rectangular slabs; Upper and lower edge at described two rectangular slabs is respectively arranged with the corrosion resistance elastic sealing strip; The doorframe back timber is provided with the sealing wind air inlet that communicates with described blade interlayer inner chamber and controls the opening/shutting valve that described sealing wind passes through; Described rotating shaft driving mechanism is the toggle that is driven by YE, and the connecting rod of described toggle is hinged with the rotating shaft of blade respectively; The blade rotor that is positioned at the doorframe inner top is hinged by the crank of connecting rod and described valve.
Be coated with anti-corrosion layer respectively at the outer surface of described rectangular slab and the inner surface of described doorframe.
The utility model advantage is that described blade is set to the sandwich that is made of two rectangular slabs, and the doorframe back timber is provided with air inlet that communicates with described blade interlayer inner chamber and the valve of controlling these air inlet opening and closing.Therefore, when the baffle door blade was closed, the blade rotor that is positioned at the doorframe inner top was opened described valve by crank connecting link, and external source of the gas is sent into blade interlayer inner chamber with pressure greater than the gas of flue gas pressures in the flue and played the hermetic seal effect; When the baffle door blade was opened, the blade rotor that is positioned at the doorframe inner top was closed described valve by crank connecting link, cuts off external source of the gas.For further improving sealing effectiveness, be respectively arranged with elastic sealing strip at the upper and lower edge of described two rectangular slabs.For prolonging the service life of blade, on the outer surface of rectangular slab, be coated with anti-corrosion layer.

Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the left TV structure schematic diagram of Fig. 1.
Fig. 3 is that the structure for amplifying schematic diagram cuts open in the office of I portion of Fig. 1.
The specific embodiment
As shown in the figure, twayblade venetian blind type damper door described in the utility model, it comprises doorframe 1, is horizontally set on a plurality of blades in the described doorframe 1 and the rotating shaft driving mechanism that is arranged on doorframe 1 outside by rotating shaft 2 from top to bottom; The sandwich of described blade for constituting by two rectangular slabs 3,4; Be respectively arranged with corrosion resistance elastic sealing strip 5,6 at the upper and lower edge of described two rectangular slabs 3,4; Doorframe 1 back timber is provided with the sealing wind air inlet 7 that communicates with described blade interlayer inner chamber and controls the opening/shutting valve 8 that described sealing wind passes through; Described rotating shaft driving mechanism is the toggle that is driven by YE 9, and the connecting rod 10 of described toggle is hinged with the rotating shaft 2 of blade respectively; The blade rotor 2 that is positioned at doorframe 1 inner top is hinged by the crank of connecting rod 11,12 and described valve 8.For improving the corrosion resistance of blade, be coated with anti-corrosion layer respectively at the outer surface of rectangular slab 3,4 and the inner surface of doorframe 1.
