Description
Technical field：
The present invention relates to a kind of swirl vane regulating device and working methods.
Background technology：
The regulating mechanism of existing swirl vane is that pull rod adds hinge arrangement, and error is larger when being assembled in factory, in cold conditions situation
Lower stated accuracy is inadequate, and eddy flow scale shows inaccurate.Temperature is higher herein when power plant's actual motion, the even stuck mistake of the easy bite of hinge
The effect of de-regulation.Influence the operation of the low nitrogen of high efficiency boiler.
Invention content：
The object of the present invention is to provide a kind of swirl vane regulating device and working methods, solve the installation of device difficulty, essence
Spend low, the inaccurate problem of eddy flow degree.
Above-mentioned purpose is realized by following technical scheme：
A kind of swirl vane regulating device, composition include：Cylinder, the inner barrel have steel plate, the steel
There is swirl vane, by axis connection in annular connecting plate, the annular connecting plate passes through the swirl vane between plate
Axis is connect with limiting plate, and the annular connecting plate is welded with pull rod.
The swirl vane regulating device is machined with waist-shaped hole on the limiting plate.
A kind of working method using the swirl vane regulating device described in one of claim 1-2, this method include such as
Lower step：
First, the swirl vane between cylinder multilayer steel plates is by the way that in axis connection to annular connecting plate, the annular is even
Limit hole is provided on fishplate bar, pull rod is welded on connecting plate, limiting plate by axis connection to the annular connecting plate, it is described
There is kidney slot on limiting plate.The annular connecting plate, the annular connecting plate are driven when pulling the pull rod outside stove
Drive the swirl vane rotation, the limiting plate that can adjust the rotational angle of the swirl vane and fix,
Determine that corresponding pull rod pulls out length according to the swirl vane angles when cold conditions is demarcated.
Beneficial effects of the present invention：
The present invention simplifies the regulating mechanism of swirl vane, so that it is assembled in factory simply, precision is improved when cold conditions is demarcated.
In power plant's actual motion, the adjustment of eddy flow degree can be carried out as required.
The present invention pulls outside stove drives annular connecting plate when pull rod, annular connecting plate drives swirl vane rotation, limit
Plate can adjust the rotational angle of swirl vane and fix, and corresponding drawing is determined according to swirl vane angles when cold conditions is demarcated
Bar pulls out length.
The present invention can be applied directly on boiler of power plant, and when boiler operatiopn can directly be adjusted according to actual conditions by pull rod
The operation of the low nitrogen of high efficiency boiler is realized in the angle of whole turbulent burner swirl vane, the generation of NOx when to reduce boiler operatiopn

Attached drawing 2 is the front view of attached drawing 1.
Attached drawing 3 is the left view of attached drawing 1.
Specific implementation mode：
Embodiment 1：
A kind of swirl vane regulating device, composition include：Cylinder 5, the inner barrel have steel plate, the steel
There is swirl vane 4, for the swirl vane by axis connection in annular connecting plate 1, the annular connecting plate is logical between plate
It crosses axis to connect with limiting plate 2, the annular connecting plate is welded with pull rod 3.
Embodiment 2：
According to swirl vane regulating device described in embodiment 1, waist-shaped hole is machined on the limiting plate.
Embodiment 3：
A kind of working method using the swirl vane regulating device described in one of claim 1-2, this method include such as
Lower step：
First, the swirl vane between cylinder multilayer steel plates is by the way that in axis connection to annular connecting plate, the annular is even
Limit hole is provided on fishplate bar, pull rod is welded on connecting plate, limiting plate by axis connection to the annular connecting plate, it is described
There is kidney slot on limiting plate.The annular connecting plate, the annular connecting plate are driven when pulling the pull rod outside stove
Drive the swirl vane rotation, the limiting plate that can adjust the rotational angle of the swirl vane and fix,
Determine that corresponding pull rod pulls out length according to the swirl vane angles when cold conditions is demarcated.
