Abstract
The utility model provides a radial reaction center pipe support aiming at solving the technical problems of flow obstacle and high temperature coking caused by retention of a catalyst of the current center pipe supports. The support mainly comprises a connecting piece, a base inner tube and an annular supporting bottom plate, wherein the base inner tube is welded above a center hole of the supporting bottom plate, and forms a material passage together with the center hole; the supporting bottom plate is uniformly distributed with a plurality of circumferential holes for a catalyst to pass by along the circumference; and the connecting piece is similar to a cone shape, one end of the connecting piece is connected with the edge of the supporting bottom plate, the other end of the connecting piece is welded with the wall of a reactor, a conical annular catalyst passage is formed between the inner wall of the connecting piece and the outer wall of a base sleeve, and the conical annular catalyst passage is communicated with the circumference holes of the supporting bottom plate. The support reduces the flowing resistance of the catalyst, ensures the smoothness of the catalyst passage, and avoids the phenomenon of the high temperature coking of the catalyst.
Description
Technical field
The utility model relates to a kind of radial reactor central tube bearing, relates to the central tube bearing of radial reactor in a kind of catalytic reforming unit specifically.
Background technology
Central tube is that reforming reactor mainly reaches the core internals, is the passage of oil gas turnover, is to isolate catalyst, realizes that the cross-flow of gas-solid two-phase contacts the critical component that carries out catalytic reaction.And the bearing of central tube is a critical component of reforming reactor internals design as the lower support structure of central tube.
The parts that are connected with reactor are contained with domestic existing reforming reactor central tube bearing in U.S. Universal Oil Products Company (UOP), these parts are connected by bolt with the outer sleeve of central tube bearing, the outer end is welded on the reactor wall, is the connector of ellipse head sample.Because ellipsoidal head forms depression around the corner, in course of reaction, catalyst easily is detained in the elliptic space, causes the situation of mobile obstacle and high-temperature coking.
The utility model content
For the catalyst that solves existing central tube bearing existence easily is detained in the elliptic space, cause the technical problem of mobile obstacle and high-temperature coking.The utility model provides a kind of radial reactor central tube bearing, and this bearing can avoid catalyst to be detained, and guarantee that catalyst channels is unimpeded and prevent the catalyst leakage, thereby the stable reaction that has guaranteed central tube is carried out.
The radial reactor central tube bearing that the utility model provides mainly is made up of connector, base sleeve and support base plate.Support base plate and be uniformly distributed with some circumferential perforates that supply catalyst to pass through along the circumference, the base sleeve is a pipe, welds mutually with the support base plate; Wherein, the support base plate is an annular, the centre bore of center for passing through for material, and base sleeve and centre bore are formed material channel jointly; Connector is similar to coniform, one end is connected with the support base panel edges, the other end welds mutually with reactor wall, forms the frusto-conical annular catalyst channels between connector inwall and the base sheath drum outer wall, and this frusto-conical annular catalyst channels communicates with the circumferential perforate of support base plate.
Owing to adopted cone shape connector, make the conical catalyst channels gradient that forms increase, avoided the depressed area on the passage, thereby make catalyst be difficult in passage, being detained, reduce the catalyst stream dynamic resistance, guaranteed that catalyst channels is unimpeded, avoided catalyst high-temperature coking phenomenon.
As further improved plan, connector of the present utility model directly welds together with the edge that supports base plate.Owing to adopted the mode of welding, eliminate bolt and connected the leakage point that may exist, guaranteed the sealing effectiveness of catalyst.
Description of drawings
The utility model will be further described below in conjunction with accompanying drawing.
Fig. 1 is the structural representation of bearing of the present utility model;
Fig. 2 is the structural representation that supports base plate 3 among Fig. 1;
Among the figure, the 1-connector, 2-base sleeve, 3-supports base plate, 4-reactor wall, the circumferential perforate of 5-, 6-centre bore
The specific embodiment
As shown in Figure 1, radial reactor central tube bearing mainly is made up of the support base plate 3 of connector 1, base sleeve 2 and annular.Support base plate 3 centers and have the centre bore 6 that passes through for material, be uniformly distributed with some circumferential perforates 5 that supply catalyst to pass through along the circumference, base sleeve 2 is welded in and supports base plate 3 centre bores 6 tops, with the centre bore 6 common material channels of forming, coniform connector 1 one ends weld mutually with support base plate 3 edges, can certainly adopt other connected mode, the other end welds mutually with reactor wall 4, form the frusto-conical annular catalyst channels between connector 1 inwall and the base sheath drum outer wall 2, this frusto-conical annular catalyst channels communicates with supporting base plate 3 circumferential perforates 5, forms catalyst channels jointly; Fig. 2 is the structural representation that supports base plate 3 among Fig. 1, and as seen from the figure, it is an annular, and the center has centre bore 6, circumferentially is evenly equipped with some circumferential perforates 5.
Claims (2)
1. a radial reactor central tube bearing mainly is made up of the support base plate of connector, base inner core and annular; Support base plate and be uniformly distributed with some circumferential perforates that supply catalyst to pass through along the circumference, the base sleeve is a pipe, welds mutually with the support base plate; It is characterized in that: the support base plate is an annular, the centre bore of center for passing through for material, and base sleeve and centre bore are formed material channel jointly; Connector is similar to coniform, one end is connected with the support base panel edges, the other end welds mutually with reactor wall, forms the frusto-conical annular catalyst channels between connector inwall and the base sheath drum outer wall, and this frusto-conical annular catalyst channels communicates with the circumferential perforate of support base plate.
