Description
Technical Field
The utility model relates to a boiler equipment technical field especially relates to a canopy cooling tube group in boiler.
Background
As a kind of heat exchange equipment, the boiler can produce a large amount of heat energy in the during operation, especially by the ceiling that the flue gas strikes, if the ceiling does not do the cooling, can produce the corruption of ceiling or even the damage of ceiling under the intersection effect of outside and inside cold and hot air current, and then lead to the flue gas to reveal, cause serious environmental pollution accident.
SUMMERY OF THE UTILITY MODEL
The utility model discloses the technical problem that will solve is: a high-ductility boiler inner ceiling cooling pipe group is provided.
For solving the technical problem, the utility model discloses the technical scheme who adopts does: a cooling pipe group of a boiler inner ceiling comprises a furnace top inlet header and a plurality of water-cooling pipes which are communicated with the furnace top inlet header and arranged in parallel, wherein horizontal cooling fins which are arranged along the axial direction of a pipe body are respectively arranged on two sides of each water-cooling pipe, a plurality of telescopic notches which are arranged along the radial direction of the pipe body of each water-cooling pipe are arranged on the cooling fins in parallel, and the cooling pipe group further comprises at least two groups of cable hole pipe assemblies and a plurality of fluid cooling positioning pipes which are arranged in the clearance of the water-cooling; the cable hole pipe assembly comprises a pipe body welded on a radiating fin, the radiating fin is provided with an avoiding hole avoiding the pipe body, the periphery of the pipe body is fixedly welded with an inner guard plate, the edges of two ends of the inner guard plate are respectively positioned at the other sides of two water-cooled pipes closest to the pipe body, and a reinforcing plate is arranged on one side, away from the water-cooled pipes, of the inner guard plate on the pipe body; at least two fluid cooling positioning pipes are respectively arranged at the positions close to the left water-cooled wall and the right water-cooled wall of the boiler, and the fluid cooling positioning pipes are arranged in a penetrating way and welded on the horizontal radiating fins at corresponding positions.
Preferably, the telescoping slot includes a rectangular opening and a rounded inner end connected.
Preferably, the pipe body is detachably provided with a cover cap.
As a preferred scheme, the top of the cover cap is provided with a bolt which is connected with a steel cable with one end welded on the pipe body.
The utility model has the advantages that: because the horizontal radiating fins of the water-cooling pipe arranged at the two sides along the axial direction of the pipe body are provided with a plurality of telescopic notches arranged along the radial direction of the pipe body of the water-cooling pipe in parallel, the radiating fins have a deformation space during heat exchange, the water-cooling pipe breakage caused by thermal deformation is avoided, and the service life of the mechanism per se is prolonged.
Because flexible notch is the rectangle opening and the circular inner end portion that are connected, and then prevent the fin in the heat exchange because the stress concentration that deformation leads to, and then prevented to lead to the fracture of fin root because stress concentration, prolonged working life.
