Description
Technical field
The present invention relates to separator technology field, more particularly to a kind of center cylinder of cyclone separator with dilatation joint.
Background technology
Cyclone separator is one of important component of CFBB, and its separative efficiency decides Matter Transfer
Multiplying power, meanwhile, its performance also determine the operational effect of boiler.As the central tube of cyclone separator, rotation not only decide
The separative efficiency of wind separator, critical effect is also played to isolation resistance.
The central tube of common cyclone separator is all integral structure, is mostly rolled using heat-resisting steel sheet and plate or monoblock cast
Form, top plate welding have and cyclone separator, some is suspended on the top plate of separator.
Cyclone separator is typically in the furnace outlet of CFBB, and residing environment temperature is mostly at 600 DEG C
Between~900 DEG C, although some cyclone separators the upper and lower of top plate in design is equipped with flame retardant coating, central tube itself
Expansion issues between expanded by heating problem and steel plate and flame retardant coating still can not be solved finally.Center cylinder of cyclone separator can be because
Cause to deform (circle becomes oval or random deformation) for expansion inequality, ultimately result in concentrated wear, cause flue gas short-circuit.
Central tube be with the top plate of cyclone separator weld, but due to boiler startup and blowing out during, central tube can undergo 500
DEG C~900 DEG C of temperature difference expand with heat and contract with cold, caused stress inevitably results in the cracking of weld seam, and final central tube comes off, and causes to stop
Stove.
The content of the invention
Weak point present in regarding to the issue above, the present invention provide a kind of cyclone separator center with dilatation joint
Cylinder.
To achieve the above object, the present invention provides a kind of center cylinder of cyclone separator with dilatation joint, including：
Central tube, the central tube are up-down structure, and the central tube is located at cylinder B's including cylinder A, the cylinder A
Upper end；
Uniformly it is machined with multiple dilatation joint A in the cylinder A bottoms, the height of the dilatation joint A is 50mm-200mm, institute
Dilatation joint A width is stated between 2mm-6mm；
Multiple dilatation joint B are uniformly machined with the cylinder B tops, dilatation joint B length is the 1/3 of cylinder B (2) length
~1/30；
The dilatation joint A and the dilatation joint B quantity, width are identical；
The external wall of upper portion of the cylinder B is welded with bearing, and the bottom of the bearing is fixed in separator top plate.
As currently preferred, the height of the dilatation joint A is 100mm.
As currently preferred, the dilatation joint A and dilatation joint B width is 4mm.
As currently preferred, the dilatation joint A and dilatation joint B top and bottom are plane.
Further improved as of the invention, the bearing is in the form of an " L ".
As currently preferred, lacing wire is welded with the middle part of the bearing.
Further improved as of the invention, the cylinder A and cylinder B is rolled for heat-resisting steel sheet and plate and formed.
As currently preferred, the cylinder A and cylinder B a diameter of 300mm-1000mm.
Beneficial effects of the present invention are：Employing the central tube with dilatation joint can eliminate because caused by expanding with heat and contract with cold
Central tube deforms, meanwhile, the central tube uses support style, avoids coming off for central tube；Central tube uses two body knots up and down
Structure, it is easily installed, repairs.
