Abstract
The invention discloses an inner cylinder for a reactor, the inner cylinder is installed on the periphery of a central pipe in the reactor, the section of the inner cylinder is trapezoidal, and a fan-shaped air lifting cylinder is fixedly connected on the upper part of the inner cylinder; a mesh plate is fixedly connected on one side face of the inner cylinder; the section of the inner cylinder is square and the mesh plate fixedly connected on the side face of the inner cylinder is a circular arc-shaped surface; a plurality of inner cylinders are fixedly installed on an annular platform on the lower part of the reactor, and the circular arc-shaped surfaces of the mesh plates are enclosed to a cylinder shape; and the mesh plate is a gap-shaped stainless steel welding net. Compared with the prior art, the invention has the advantages that the structure is simple, and that the inner cylinder is of a single cylindrical structure, so the inner cylinder is singly installed to be conveniently installed; the inner cylinder is a cylinder with a trapezoidal or square section, so that the cross-sectional area of the cylinder shape enclosed by the inner cylinders is larger than that of the cylinder shape enclosed by the fan-shaped cylinder, thereby reducing the catalyst dosage, relieving the integral weight of the reactor and reducing the potential safety hazard and fund investment.
Description
Technical field
The present invention relates to a kind of tube structure, specifically a kind of reactor that is applied in the petroleum industry oil refining production system is used inner core.
Background technology
China's rate of industrial development is very fast, and especially the oil refining industry of petroleum industry development local flavor is swift and violent.A lot of outputs are 1,000,000 tons/year oil refinery company, and their equipment is generally from external introduction, and what in the production system of petroleum industry oil plant, can not lack is exactly cylindrical shape reforming reactor or hydrogenation reactor.At present, main internals composition is central tube and sector drum in the reforming reactor, perhaps is central tube and outer net.In actual use; Because the top end socket of reactor and circular cylinder body welding are fixing, outer net damages the back and can not take out from manhole, can only keep in repair at inside reactor; Can reduce the percent opening of outer net after the maintenance; Increase the perforate inhomogeneities of cylindrical shell, also caused the inhomogeneous of outer net intensity, influenced the service life of normal operating conditions and outer net; Reactor outer net internals are changed to the sector drum combiner, can more renew part after a sector drum damages, maintenance is convenient than outer net; But the present sector drum of producing is fan-shaped, and the reactor inner tube wall is leaned at the back side of sector drum during installation, like the sector drum perforated area when identical with the outer net perforated area; Just increased the shared area of section of catalyst; Just increase the catalyst between outer net outer surface to the sector drum semicircular surface, not only increased the weight of reactor monolith, also had very big potential safety hazard; And catalyst costs an arm and a leg, and has increased fund input.
Summary of the invention
The present invention be directed to outer net and central tube in the prior art and change to the deficiency of central tube and sector drum combination, provide a kind of reactor simple in structure, easy to maintenance, that reduce the catalyst use amount to use inner core.
Realize that the technical scheme that above-mentioned purpose adopts is: a kind of reactor is used inner core, and the central tube of this inner tube installation in reactor is peripheral, and the cross section of said inner core is trapezoidal, and the top of this inner core is connected with the fan-shaped inflator that rises; A side of said inner core is connected with web plate.
The cross section of inner core is square.
The web plate that is fixed in the inner core side is an arc surface.
A plurality of inner cores are fixedly mounted on the annular table of reactor lower part, and the arc surface of each web plate surrounds a cylindrical shape.
Web plate is a gap-shaped stainless steel welded mesh.
Compared with prior art, the present invention is simple in structure, and each inner core is single tubular structure, and independent installation is easy to maintenance; Because inner core is that the cross section is the cylindrical shell of trapezoidal or square structure, the cylindrical shape that inner core surrounds is big than the cylindrical shape area of section that sector drum surrounds, and reduces catalyst consumption, alleviates reactor monolith weight, reduces potential safety hazard and fund input.
Description of drawings
Fig. 1 is an overall structure sketch map of the present invention.
Fig. 2 is a vertical view of the present invention.
Fig. 3 is an installation site of the present invention sketch map.
Among the figure: rise inflator 1, inner core 2, web plate 3, base plate 4, connecting plate 5, reactor 6, central tube 7.
The specific embodiment
Below in conjunction with accompanying drawing the present invention is further specified.
Referring to accompanying drawing 1-3, the cross section of the disclosed this inner core of the present invention is trapezoidal or square structure.
This reactor is with central tube 7 peripheries of inner tube installation in reactor 6.The cross section of inner core 2 is a rectangle, and the top of this inner core 2 is connected with the fan-shaped inflator 1 that rises, and rises on the connecting plate 5 that inflator is arranged on the inner core top.A side of inner core 2 is connected with web plate 3.The web plate 3 that is fixed in inner core 2 sides is arc surface.A plurality of inner cores 2 are fixedly mounted on the annular table of reactor 6 bottoms, and each inner core leans on reactor wall to install, and the base plate 4 of inner core is erect and is arranged on the annular table, and the arc surface of each web plate 3 surrounds a cylindrical shape.Web plate 3 is gap-shaped stainless steel welded mesh, i.e. Johnson's net.
When mounted, inner core the inner surface of web plate one side and former outer net at same position, the columnar circumference that is promptly surrounded by the arc surface of the web plate on the inner core is identical with the circle diameter of former outer net inner surface.Like this,, reduced the shared relative area of reactor shell inner catalyst,, lowered hidden danger, saved fund input so reduced the use amount of catalyst because setting trapezoidal or square inner core is compared with original sector drum.
Claims (5)
1. a reactor is used inner core, and the central tube of this inner tube installation in reactor is peripheral, it is characterized in that the cross section of said inner core is trapezoidal, and the top of this inner core is connected with the fan-shaped inflator that rises; A side of said inner core is connected with web plate.
