Description
Technical field
The utility model relates to the interior arrangement of hydrogenation reactor, especially relates to a kind of reactor outlet collector.
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, its bottom beds needs supported, and reaction mass should have unobstructed runner to flow out.Traditional exit collector screen net structure pressure drop is bigger, easily stops up.
The utility model content
The purpose of this utility model is exactly that a kind of simple in structure, self pressure drop is little, runner is unobstructed, easy for installation reactor outlet collector is provided in order to overcome the defective that above-mentioned prior art exists.
The purpose of this utility model can be achieved through the following technical solutions: a kind of reactor outlet collector, be arranged on reactor bottom (head) inboard, it is characterized in that, this reactor outlet collector comprises top cover, cylindrical shell, support plate, described top cover is arranged on the cylindrical shell top, cover cylindrical shell, described cylindrical shell side is provided with a plurality of support plates, this support plate is connected by securing member with fixed head on being welded on the reactor bottom (head), the reactor outlet collector is fixed on the reactor, described locating ring is arranged on the reactor bottom (head) sidewall, links to each other with the cylindrical shell lower end of reactor outlet collector.
Described top cover and cylindrical shell are formed by the main body of wedge shape web frame and the end plate that is located at the main body border, and described wedge shape web frame mainly is made up of the pressing plate, wedge shape net, the support plate that connect successively and a plurality of gussets of being located at the support plate opposite side.
The channel cross-section of described wedge shape net is a wedge shape, and the small end in wedgy passage cross section is for flowing into end, and big end is outflow end.
Respectively have through hole on described locating ring and outlet collector and the lower edge that bottom (head) contact, locating ring is connected passage of formation afterwards with the reactor outlet collector.
Described reactor outlet collector is from middle dimidiation, and two halves are connected with securing member by connecting plate.
Compared with prior art, the utlity model has simple in structure, advantage such as self pressure drop is little, runner is unobstructed, easy for installation.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is the partial enlarged drawing at I place among Fig. 1;
Fig. 3 is the partial enlarged drawing at II place among Fig. 1.
1 is that top cover, 2 is that connecting plate, 3 is that securing member, 4 is that fixed head, 5 is that support plate, 6 is that locating ring, 7 is that cylindrical shell, 8 is a through hole among Fig. 1.
21 is that pressing plate, 22 is that wedge shape net, 23 is that support plate, 24 is that gusset, 25 is end plate among Fig. 2.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is elaborated.
As Fig. 1, Fig. 2, shown in Figure 3, a kind of reactor outlet collector is arranged on reactor bottom (head) inboard, and this reactor outlet collector comprises top cover 1, cylindrical shell 7, connecting plate 2, support plate 5, fixed head 4, locating ring 6, securing member 3.Top cover 1 and cylindrical shell 7 are formed by the main body of wedge shape web frame and the end plate 25 that is located at the main body border, and the wedge shape web frame mainly is made up of the pressing plate 21, wedge shape net 22, the support plate 23 that connect successively and a plurality of gussets 24 of being located at the support plate opposite side.The channel cross-section of wedge shape net 22 is a wedge shape, and the small end in wedgy passage cross section is for flowing into end, and big end is outflow end.Cylindrical shell 7 is provided with support plate 5, this support plate 5 is connected by securing member with the fixed head 4 that is welded on reactor bottom (head) side, the reactor outlet collector is fixed on the reactor, locating ring 6 is arranged on the reactor bottom (head) sidewall, respectively have breach on this locating ring 6 and outlet collector and the lower edge that bottom (head) contact, locating ring 6 is connected hole of formation afterwards with the reactor outlet collector.This reactor outlet collector is from middle dimidiation, and two halves are connected with securing member by connecting plate 2.Wedge shape net 22 directly contacts with porcelain ball or catalyst.Reaction mass is increasing because of cross sectional area during by wedge shape net 22, and in a single day solid impurity enters and can flow out smoothly from the other end, so be difficult for stopping up.Wedge shape net 22 circulation areas are big, the percent opening height, and pressure drop is little, has the good rheid that contains and passes through performance.Outlet collector cylindrical shell is provided with support plate 5, by support plate 5 be welded in fixed head 4 usefulness securing members on the reactor bottom (head) and will export collector and be fixed on the reactor.Also be provided with locating ring 6 on the reactor bottom (head), accurately locate to help the outlet collector.Respectively have through hole 8 on locating ring 6 and outlet collector and the lower edge that bottom (head) contact, locating ring 6 is connected passage of formation afterwards with the reactor outlet collector, so that the interior raffinate of emptying reactor.The outlet collector is from middle dimidiation, and each partly all can pass in and out from manhole.Utilize connecting plate and securing member that it is assembled into an integral body during installation.
