Description

A kind of reactor catalyst support grid beam

Technical field

The utility model relates to the interior arrangement of hydrogenation reactor, especially relates to a kind of reactor catalyst support grid beam.

Background technology

Hydrogenation reactor is one of key equipment in all kinds of oil hydrogenation plants.Hydrogenation reactor is a multilayer heat insulation, and is middle hydrogen-cooled, and volatile component is taken the phase reactor of heat and a large amount of hydrogen circulations.The quality of inside reactor device performance has determined the advance of hydrogenation technique with catalyst performance.The hydrogenation reactor interior arrangement should have good performance.Gas-liquid two-phase has comprehensive mixing; Liquid-solid two-phase has contact fully completely; The catalyst surfaces externally and internally has enough wetting, and catalyst activity is fully played.The hydrogenation reactor interior arrangement should have lower pressure drop, to reduce the load of circulating hydrogen compressor, saves energy consumption.The structure of hydrogenation reactor interior arrangement also should be simple, compact, occupies little space, to reduce expensive hydrogenation reactor investment.For the enterprising trickle bed reactor that goes out down, the load of its beds is huge, except quality, the catalyst of grid beam self and be stained with liquid and coking amount, flow velocity increases that the pressure that produces falls and the pressure of grid beam generation itself falls in the time of also will considering fluid pressure drop, the emergency blow-down after the bed coking.Traditional catalyst supports grid girder construction complexity, Turbogrid plates intensity is low, and the bearing capacity deficiency.

The utility model content

The purpose of this utility model be exactly provide in order to overcome the defective that above-mentioned prior art exists a kind of structure configuration rationally, bearing capacity is strong, self pressure drop is little, runner is unobstructed, reveal less, firm firm reactor catalyst support grid beam.

The purpose of this utility model can be achieved through the following technical solutions: a kind of reactor catalyst support grid beam, be arranged in the reactor, be provided with the annular collar tie beam that is used to install reactor catalyst support grid beam in the described reactor, it is characterized in that, this support grid beam comprises two girders, polylith Turbogrid plates, described two girder parallel interval are arranged on the ring wale, and described Turbogrid plates are arranged between two girders and between girder and the annular collar tie beam.

Described girder comprises transverse slat and riser, and described riser is arranged on the transverse slat, becomes inverted T shape.

The top of described riser is taper.

Described Turbogrid plates comprise press strip, wedge shape net, a plurality of grid bar, are located at the end plate of Turbogrid plates periphery, and described press strip is arranged on the top of wedge shape net, and described grid bar parallel interval is arranged on the below of wedge shape net, fixedly connected with end plate in two ends.

The top of described press strip is provided with hanger.

The channel cross-section of described wedge shape net is a wedge shape, and the small end in wedgy passage cross section is held down greatly up.

Between the end plate and girder of described Turbogrid plates, be provided with between the end plate of Turbogrid plates and the annular collar tie beam and can reduce the sealing pottery towline that catalyst leaks.

Compared with prior art, the utlity model has structure configuration rationally, bearing capacity is strong, self pressure drop is little, runner is unobstructed, reveal less, firm advantage such as firm.

The specific embodiment

Below in conjunction with the drawings and specific embodiments the utility model is elaborated.

Embodiment

As shown in Figure 1 and Figure 2,

A kind of hydrogenation reactor inside that is installed in can make reactor catalyst safety support to reactor catalyst support grid beam on the reactor wall.Hydrogenation reactor catalyst grid beam is made up of parts such as 2 girders, flase floor 4, annular collar tie beam 1 and sealing pottery towlines 5, sees structural representation Fig. 1, Fig. 2.Annular collar tie beam 1 is soldered on the reactor wall in the mode of built-up welding.Reactor wall basic unit identical materials is used in basic unit's built-up welding, and the multiple layer of reactor wall identical materials used in the built-up welding of multiple layer.2 girder parallel interval are arranged on the annular collar tie beam 1, flase floor 4 be bearing between two girders and girder and annular collar tie beam 1 on, constituted the grid beam of complete reliable supporting structure system jointly.Girder adopts the complete penetraction and fusion in welding pattern to be welded by transverse slat 3 and riser 2, and transverse slat 3 is following, and riser 2 is at last formation inverted T-shaped.Transverse slat 3 makes its cross sectional moment of inertia and module of anti-bending section reach necessary level with the reasonable combination of riser 2, possesses enough powerful bearing capacity.Riser 2 tops are taper, to reduce resistance.Flase floor 4 is made of wedge shape net 32, grid bar 34, press strip 31, end plate 35 and hanger 33 etc., sees structural representation Fig. 3, Fig. 4.Wedge shape net 32 is arranged on upper surface and replaces traditional braiding class silk screen, and 34 load-bearing of grid bar are arranged at the bottom.Wedge shape net 32 directly contacts with porcelain ball or catalyst.The channel cross-section of wedge shape net 32 is a wedge shape, and the small end in wedgy passage cross section is held down greatly up, sees Fig. 4.Reaction feed is increasing because of cross sectional area during by wedge shape net 32, and in a single day solids enters and can flow out smoothly from the other end, so be difficult for stopping up.Wedge shape net 32 circulation areas are big, the percent opening height, and pressure drop is little, has the good rheid that contains and passes through performance.Be tied with sealing pottery towline 5 between the end plate 35 of flase floor 4 and the girder, leak to reduce.The flase floor semi-finals degree height of this wedge shape web frame, good integrity, pressure drop is little, the percent opening height, pressure drop is little, and working stability is reliable.
