Abstract
The utility model discloses a concentrated pipe cecum for vortex -resistant flange lap, be in including flange flat cover and welding the inboard vortex -resistant structure of flange flat cover, the vortex -resistant structure includes the cylinder of a plurality of apertures of side wall surface evenly distributed and is in along longitudinal welding three mutually unidimensional rectangular plates that separate angle 120 degrees each other of circle cylinder side wall face, vortex -resistant structure and the coincidence of flange flat cover axis, the cylinder external diameter is less than the flange internal diameter with rectangular plate length sum, there is the clearance in three mutually unidimensional rectangular plates with the flange inner wall face. The fluid flow is during to the concentrated pipe cecum, this for the vortex -resistant flange apron can eliminate the vortex that the concentrated pipe cecum produced, prevent that the cecum wall from being washed out, avoid the cecum to take place to corrode, guarantee the continuous safe operation of heating furnace, and simple structure, make simple to operate.
Description
Technical field
This utility model relates to the accessory of a kind of petrochemical industry heating furnace tube, specifically a kind of anti-eddy current flange plate of collecting tubule cecum.
Background technology
At present, the gateway of petrochemical industry heating furnace tube be substantially with collecting tubule connect, collecting tubule cecum all adopts flange flat cover to block.Fluid enters after collecting tubule through boiler tube, owing to the closure of flange flat cover causes that fluid produces eddy current at collecting tubule cecum wall, collecting tubule cecum wall long-continued can be produced erosion by this eddy current, causes collecting tubule cecum wall corrosion thinning the most at last, affects heating furnace properly functioning.Collecting tubule cecum strength of vortex and heating furnace treating capacity are proportional, if improving the yield of product, will certainly increase the treating capacity of heating furnace, and result is by more serious for the erosion causing collecting tubule cecum wall.
Summary of the invention
In order to overcome existing collecting tubule cecum flange flat cover can not the deficiency of anti-eddy-currents, this utility model provides a kind of anti-eddy current flange plate of collecting tubule cecum.
This utility model solves its technical problem and be the technical scheme is that a kind of anti-eddy current flange plate of collecting tubule cecum, including flange flat cover and anti-vortex structure, described anti-vortex structure includes side wall surface and is uniformly distributed the cylinder of multiple aperture and is longitudinally welded on the three pieces of same size rectangular slabs being spaced angle 120 degree of described cylinder side wall surface.
Described anti-vortex structure overlaps with flange flat cover axis, and described anti-vortex structure is welded to inside flange flat cover；Described cylinder external diameter and rectangular slab length sum are less than flange inner diameter, and described three pieces of same size rectangular slabs and flange inner wall face exist gap.
When fluid stream is to collecting tubule cecum, flowing through described anti-vortex structure, will not form the eddy-currents of big intensity, define the eddy current that some vorticity intensity are very little, collecting tubule cecum wall will not be produced erosion by these little eddy current, it is to avoid corrosion occurs.
The beneficial effects of the utility model are: can eliminate the eddy current that collecting tubule cecum produces, it is prevented that cecum wall is by erosion, it is to avoid cecum corrodes, it is ensured that the continuous safe operation of heating furnace, and simple in construction, manufactures easy for installation.
Accompanying drawing explanation
Fig. 1 is the perspective view of this utility model embodiment.
Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model is described in further detail.
As shown in Figure 1: the anti-eddy current flange plate of a kind of collecting tubule cecum of the present embodiment, it includes flange flat cover 1, welding anti-vortex structure inside described flange flat cover 1, described anti-vortex structure includes side wall surface and is uniformly distributed the cylinder 2 of multiple aperture 4 and is longitudinally welded on the three pieces of same size rectangular slabs 3 being spaced angle 120 degree of described cylinder 2 side wall surface.Described anti-vortex structure overlaps with flange flat cover 1 axis, and described anti-vortex structure is welded to inside flange flat cover 1.Described cylinder 2 external diameter and rectangular slab 3 length sum are less than flange inner diameter, and described three pieces of same size rectangular slabs 3 exist gap with flange inner wall face.Fluid stream, to collecting tubule cecum, flows through described cylinder 3 and described rectangular slab 2, after described aperture 4, and the vortex that fluid velocity reduces and do not produce, will not produce to wash away to collecting tubule cecum wall, it is to avoid corrosion occurs.
