Abstract
The utility model is suitable for a sealing supporting device for catalysts in a reactor which is filled with the catalysts. The utility model comprises an asbestos cord 1, a pressing plate 5, a wire mesh 4, a hole plate 6, grids 7, etc. The utility model is characterized in that the device also comprises a vertical plate 2, and the vertical plate 2 and the pressing plate 5 are welded into a whole; the pressing plate 5, the wire mesh 4 and the hole plate 6 are fixed through bolts 3. The utility model has the characteristics of simple structure, easy processing, simple installation and tight and reliable sealing, and the utility model can ensure that the catalysts can not leak when the utility model runs for a long time. The stability and the long-period operation of the processing device are ensured, and obvious economic benefits for a plant are brought.
Description
Technical field
The utility model relates to a kind of sealing bracing or strutting arrangement of chemical machinery, is specially adapted to be equipped with the sealing bracing or strutting arrangement of the catalyst reactor of catalyst.
Background technology
In chemical production device, in the reactor of the catalyst reaction section of loading some, general every layer of conversion zone is orifice plate (6) the upper berth silk screen (4) in activity, use annular pressing plate (9) and tower tray clamp (10) that the edge of silk screen (4) is pushed down again, go up loading catalyst at silk screen (4) again.If the diameter of the catalyst granules that uses is very little, catalyst is easy to spill from the gap of the gap of orifice plate (6) and cylindrical shell (8) and clamp (10) and bolt hole.So if seal badly herein, catalyst will take place and leak in device in running, influence product quality even etching apparatus.Present encapsulating method all adopts between pressing plate (9) and cylindrical shell (8) and clogs asbestos cord (1) (Fig. 1), this kind method is because of being subjected to the influence of mounting condition, pressing plate (9) and cylindrical shell (8) gap too little (restriction that compression plate (9) can not excessively be thickeied), asbestos cord (1) filling is few, and asbestos cord (1) lap-joint is prone to leak, even if sealed up at that time, along with when operation device material wash away and the influence of the phenomenon of expanding with heat and contract with cold, asbestos cord (1) is easy to come off, cause catalyst to leak, threaten the stable operation of device.
Summary of the invention
The purpose of this utility model is to overcome the defective in the present technology, provides a kind of simple in structure, easily processing, installs simple and easy, the permanent sealing problem of solution catalyst, the stable operation of assurance device.
To achieve these goals, the utility model comprises orifice plate (6), pressing plate (5), silk screen (4), bolt (3), grizzly bar (7), riser (2) etc., riser (2) is integrally welded with pressing plate (5), the integral body of riser (2) and pressing plate (5) welding can be the whole annular that matches with cylindrical shell (8) diameter, can be the arc of segmentation also, can be spliced into annular.The height of riser (2) and riser (2) are determined to load 2～3 circle asbestos cords (1) with the gap of cylindrical shell (8).Edge at orifice plate (6) processes several bolts hole, pressing plate (5) and orifice plate (6) is joined bore the bolt hole that single ended bolt is used simultaneously, again the screw on the pressing plate (5) is carried out reaming.Single ended bolt (3) was passed from orifice plate (6) end, and bolt (3) can carry out seal weld in orifice plate (6) bottom with orifice plate (6), with bolt with the fixing (see figure 2) of pressing plate (5) and silk screen (4).The method has solved the use tower tray and has connected the problem that has the screw place to leak with clamp (10).
, silk screen (4) big at cylindrical shell (8) diameter can not be with whole covering, and when needing splicing, then the pressing plate (9) that need process slivering at silk screen (4) lap is pushed down splicing seams, and it is connected employing bolt (3) connection with orifice plate (6), and mounting means as previously mentioned.
The utlity model has simple in structurely, easily processing is installed simple and easyly, and sealing closely reliably, can guarantee the characteristics that can not leak in the catalyst long-time running.Guaranteed stable, the long-term operation of process unit, brought tangible economic benefit to factory.

The specific embodiment
The utility model comprises orifice plate (6), pressing plate (5), silk screen (4), bolt (3), grizzly bar (7), riser (2) etc., riser (2) is integrally welded with pressing plate (5), for preventing that riser (2) and pressing plate (5) are out of shape it and are connected seam and adopt full weld on one side, another side adopts intermittent weld.The gap of the height of riser (2) and riser (2) and cylindrical shell (8) determines to load 2～3 circle asbestos cords (1), the lap-joint of the every two adjacent rings asbestos cord certain angle that staggers, and the 2nd circle staggers 180 ° with the 1st circle, and the 3rd circle staggers 120 ° with per 2 circles.Edge at orifice plate (6) processes several bolts hole, pressing plate (5) and orifice plate (6) is joined bore the bolt hole that single ended bolt is used simultaneously, again the screw on the pressing plate (5) is carried out reaming.Single ended bolt (3) was passed from orifice plate (6) end, and bolt (3) carries out seal weld in orifice plate (6) bottom with orifice plate (6), and is with bolt that pressing plate (5) and silk screen (4) is fixing.
Claims (2)
1, a kind of sealing bracing or strutting arrangement of catalyst reactor, comprise: asbestos cord (1), pressing plate (5), silk screen (4), orifice plate (6), grizzly bar (7) etc., it is characterized in that, described device also comprises riser (2), riser (2) is integrally welded with pressing plate (5), and pressing plate (5), silk screen (4), orifice plate (6) are fixed by bolt (3).
2, the described sealing bracing or strutting arrangement of claim 1 is characterized in that the integral body that riser (2) and pressing plate (5) are welded into is divided into plurality of sections, and each section can be spliced into the annular that matches with cylindrical shell (8) diameter.
