Abstract
The utility model relates to a tube array support device for a methanol reactor, which is characterized by comprising a plurality of supports disposed in parallel inside a reactor casing. Each support includes an annular frame matching with the inner cross section of the reactor casing and a plurality of support bars disposed at intervals in the annular frame, and each support bar is provided with support rings at intervals for penetration of the corresponding tube array. When the tube array support device is compared with the prior art, the support device is designed into a support bar structure with larger mutually spaced gaps, passage rate of catalyst is increased greatly, drawbacks of non-full and non-uniform filling of the catalyst among layers are overcome, and filling blind angles for the catalyst are eliminated thoroughly. Further, the tube array support device is capable of absorbing shock for tube arrays, is convenient and easy in processing and low in manufacturing cost.
Description
Technical field
The utility model relates to chemical reaction device, specifically refers to tubulation bracing or strutting arrangement in a kind of reactor.
Background technology
Development along with industrial technology, various large-scale chemical industry equipments are more and more, and for some exothermic reactions, for example methanol synthesis reactor, CO change furnace, Fischer-Tropsch synthesis device etc., the nucleus equipment of these reactors are arranged on the heat-exchanger rig in the reactor shell.Described heat-exchanger rig generally include be parallel to each other vertically be arranged on many heat exchanger tubes in the reactor shell, also claim tubulation, then loading catalyst in the space of these tubulations.With the methanol synthesis reactor is example, and the upper/lower terminal of these heat exchanger tubes is communicated with upper and lower annular tubesheet (or ring main) respectively, and upper and lower annular tubesheet (or house steward) is the circulating cooling system of coupled reaction device outside then.Because heat exchanger tube is very long, and also is filled with catalyst between each tubulation in the reactor shell, these long tubulations are supported so bracing or strutting arrangement need be set in reactor shell.
As shown in Figure 1, existing bracing or strutting arrangement generally includes and is arranged on the gripper shoe 1 that the polylith in the reactor shell is parallel to each other, the shape of each gripper shoe roughly shape with the reactor shell cross section is identical, offer on the gripper shoe for described tubulation and wear a plurality of pores 11, shake as tubulation, because gripper shoe is thinner, be generally 8～10mm, when vibration takes place, this thin pore edge is equivalent to cutter and damages tubulation repeatedly, and these pore edges on the very easily supported plate of tubulation are cut and caused tubulation to lose efficacy.The edge of gripper shoe is fixed on the inwall of reactor shell, adopts the mode of welding to fix usually; Each tubulation passes the support, spacing of the plate that is supported behind the pore on each gripper shoe, relatively firmly.
Because the isolation of gripper shoe and stopping, so the filling difficulty relatively just of catalyst between each gripper shoe, catalyst is generally from the top filling, because the space resemble the present invention not between each pore of gripper shoe, the catalyst percent of pass is extremely low, therefore filling difficulty.Also, gripper shoe has the dead band because hanging down the catalyst filling that makes between the gripper shoe in the voidage of vertical direction; Catalyst can not be packed into from the top of reactor simultaneously, because catalyst can not pass each layer gripper shoe and arrive lower floor under the isolation of gripper shoe.
The filling of catalyst for convenience, people have also designed the bracing or strutting arrangement of cell structure as shown in Figure 2.The bracing or strutting arrangement of grating type is that each tubulation is interted in each grid intersects the space that constitutes.Have certain space though such structure makes between the grid of adjacent two layers, catalyst can pass in these spaces and enter down one deck grid, thereby catalyst can be added from the top of reactor.But the bracing or strutting arrangement occupation space of cell structure is bigger, can hinder flowing of reaction medium; Because the hole on each layer grid is vertical corresponding, therefore, there is the dead angle in the filling of catalyst simultaneously.
Summary of the invention
Technical problem to be solved in the utility model is that the present situation at prior art provides a kind of catalyst to add from the methanol reactor top and filling is used for the tubulation bracing or strutting arrangement of methanol reactor uniformly.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: this is used for the tubulation bracing or strutting arrangement of methanol reactor, it is characterized in that comprising a plurality of bracing frames that are set in parallel in the reactor shell, support frame as described above comprise with reactor shell in the suitable annular frame of cross section and be disposed on many support bars in this annular frame, and be interval with the support ring that passes for each tubulation on each support bar.
Described support bar comprises first gripper shoe and second gripper shoe; Wherein first gripper shoe comprises straightway and the semicircular segmental arc that is provided with at interval, described second gripper shoe and first gripper shoe are symmetrical arranged, and both partly link together by corresponding straightway, and both corresponding segmental arc butt joint backs constitute the pore of each tubulation in the described methanol reactor.
Described first gripper shoe and the corresponding straightway of described second gripper shoe partly are fixed by welding in together.
The two ends of each described support bar are by being welded to connect on described annular frame, and described annular frame also in the form of sheets.
Compared with prior art, the utility model is designed to each other the bigger support bar structure in space at interval with bracing or strutting arrangement, therefore the percent of pass of catalyst increases substantially, and it is discontented and load uneven drawback to have eliminated every interlayer catalyst filling, has thoroughly eliminated the filling dead angle of catalyst; The present invention simultaneously can play the effect to the tubulation damping; And easy row easy to process, low cost of manufacture.

The specific embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
To shown in Figure 5, this reactor tubulation bracing or strutting arrangement comprises as Fig. 2:
First gripper shoe, 1, the first gripper shoe 1 has a plurality of straightways 11 and a plurality of semicircular segmental arc 12 that are provided with at interval in the form of sheets.
Support bar has many, and the length of each support bar with its string of a musical instrument of support ring 3 positions of corresponding installation suitable.
Support ring 3, annulus in the form of sheets is used to locate each support bar.The two ends of support bar are fixed in the support ring 3 by the mode of welding.Support ring 3 and location many support bars within it constitute the bracing frame of present embodiment.
A plurality of bracing frames are disposed in the reactor shell in parallel to each other, and support ring is positioned on the inwall of reactor shell.Each heat exchanger tube intert in hoop support, the location.Because gapped at interval between each support bar, and these gaps are distributions straggly, so when the reactor top added catalyst, catalyst not only can drain to the bottom of reactor at an easy rate, and can not produce the dead angle.
