Description
Technical field
The utility model relates to the air door product in flue gas desulfurization and denitrification system, in particular to a kind of energy saving air duct baffle
Door.
Background technique
Air channel barrier door is a kind of air door product applied in flue gas desulfurization and denitrification system, is generally mounted for absorption tower
In flue gas pipeline in inlet and outlet or bypass flue.Air channel barrier door uses venetian blind type double-layer structure, bilayer valve plate when shutdown
Between be passed through sealing air, realize completely isolated shutdown flue gas.Flue gas is typically due to certain temperature, the sealing air being blown into is certainly
Right air has certain temperature difference, so can make valve plate surface sweating, because the substances such as sulfur-bearing and nitre will form corrosivity acids in flue gas
Substance corrodes valve plate, so the service life of valve can be reduced.The method generallyd use at present is to use corrosion resisting alloy
Steel uses air heater.It is high with corrosion-resisting alloy steel cost of manufacture, increase the cost of the production and operation.It is heated using air
Device effect is obvious, is widely used.But need to be passed through that sealing air quantity is big, and energy consumption is high inside existing valve plate.Therefore, it is necessary to set
Count a kind of energy saving air duct baffle door of low energy consumption.
Summary of the invention
The technical problem to be solved by the utility model is to provide a kind of energy saving air duct baffle doors, reduce making for sealing air
Dosage, energy conservation lower consumption, reduce enterprise operation cost.
To achieve the above object, the utility model is implemented with the following technical solutions:
A kind of energy saving air duct baffle door, including valve body, double-deck valve plate, electric operator；Electric operator passes through company
The shaft of linkage connected double-layer valve plate, drives the double-deck valve plate rotation, and the double-deck valve plate is surrounded by the close wind groove of valve plate, the close wind of valve plate
Slot upper and lower surface is fixedly connected with valve plate cover board, is equipped with the guide duct being connected to the close wind groove of valve plate, valve between the close wind groove of two side valve plates
Internal wall is surrounded by the close wind groove of valve body, the close wind groove of valve body and the close wind groove of valve plate and is tightly connected by sealing strip, two neighboring double
The close wind groove of valve plate between layer valve plate is tightly connected by sealing strip, when baffle door is closed, the internal net for forming transverse and longitudinal and communicating
Shape seals wind groove, and valve body side is equipped with the sealing air entrance being connected to netted sealing wind groove, is equipped with sealing air in sealing air entrance
Butterfly valve, electric operator are connect by link mechanism with sealing air butterfly valve, and when the double-deck valve plate is opened, sealing air butterfly valve is closed,
When the double-deck valve plate is closed, sealing air butterfly valve is opened.
The guide duct is square tube or round tube.
The sealing air entrance connects sealing air blower.
Compared with prior art, the beneficial effects of the utility model are:
The utility model uses netted sealing air slot structure, and the usage amount for improving wind pressure, reducing sealing air makes sealing air
Power of fan is substantially reduced, and especially with the baffle door of heater, is even more greatly reduced the power of heater, is produced very
Good energy-saving effect.Operating cost is not only reduced, and great advantage is energy conservation, consumption reduction.

Specific embodiment
Specific embodiment of the present utility model is further illustrated with reference to the accompanying drawing:
Such as Fig. 1-Fig. 6, a kind of energy saving air duct baffle door, including valve body 1, double-deck valve plate 2, electric operator 3, sealing air
Entrance 4；Electric operator 3 passes through the shaft 11 of 5 connected double-layer valve plate 2 of link mechanism, and the double-deck valve plate 2 is driven to rotate.It is double-deck
Valve plate 2 can be multiple or 1.
Double-deck 2 surrounding of valve plate makes the close wind groove 8 of valve plate using channel steel, and close 8 upper and lower surface of wind groove of valve plate is fixedly connected with valve plate
Cover board 12 processes symmetrical ventilation opening 13 in the close wind groove 8 of two side valve plates, guide duct 9 is fixedly connected between two sides ventilation opening 13,
Guide duct 9 is square tube or round tube.
1 inner wall surrounding of valve body is fixedly connected with the close wind groove 7 of valve body of channel steel production, and the close wind groove 7 of valve body and the close wind groove 8 of valve plate are logical
The sealed connection of sealing strip 10 is crossed, closed ventilating duct is formed, the close wind groove 8 of valve plate between two neighboring bilayer valve plate 2 passes through close
Strip of paper used for sealing 10 is tightly connected, and forms closed ventilating duct.When baffle door is closed, the internal netted sealing air for forming transverse and longitudinal and communicating
Slot.
1 side of valve body is equipped with the sealing air entrance 4 being connected to netted sealing wind groove, is equipped with sealing air in sealing air entrance 4
Butterfly valve 6, electric operator 3 are connect by link mechanism 5 with sealing air butterfly valve 6, when the double-deck valve plate 2 is opened, sealing air butterfly valve 6
It closes.When the double-deck valve plate 2 is closed, sealing air butterfly valve 6 is opened.Sealing air entrance 6 connects sealing air blower.Sealing air blower can connect
Connect air heater connection.
After sealing air enters baffle door from sealing air entrance, sealing air runs through netted sealing wind groove full of baffle door,
Wind pressure is increased, fast sealing air duct reduces the usage amount of sealing air, and sealing air power of fan reduces.For band having heaters
Baffle door, then reduce the power of heater, have the characteristics that energy conservation, lower consumption, reduce production run cost.
Described above is only the basic principle of the utility model, is not imposed any restrictions to the utility model, all foundations
The utility model carries out equivalent variations and modification to it, within the scope of the art of this patent protection scheme.
