Description
Technical field
This utility model relates to the reactor in pressure vessel industries hydrogenation plant, particularly relates to hydrogenation plant reactor cold
The inner member of hydrogen mouth.
Background technology
In oil plant, the quality of cold hydrogen mouth inner member design is installed directly influencing and the complexity of dismounting, shadow
Ring project progress, the maintenance affecting the later stage and maintenance cost.Installation can be made by improving the design of cold hydrogen mouth inner member and tear open
Unloading and be more prone to, project progress is more quick, reduce maintenance and the maintenance cost in later stage.Maker and installation company are come
Say, workload and work difficulty can be reduced, improve work efficiency, for the user, later stage shut-down (breakdown) mainteance can be reduced
Time maintenance and maintenance cost.
The structure of current hydrogenation reactor cold hydrogen mouth inner member is mainly cold hydrogen tube and directly welds mutually with cold hydrogen mouth companion flange
The structure connect, the space that this structure needs when installing and dismantle is relatively big, and structure is the heaviest, installs and dismantle difficulty relatively big, peace
Dress and removal efficiency are relatively low, due to the cold hydrogen all stainless steel materials of mouth pipeline, need the pipeline destroyed longer during later stage maintenance,
Thus the stainless steel material waste caused is relatively greatly, safeguards and the cost of overhaul is higher.
Utility model content
The purpose of this utility model is to overcome problems of the prior art, it is provided that a kind of cold hydrogen mouth inner member.
Cold hydrogen mouth inner member of the present utility model, it includes alignment pin, hot box outside head, cold hydrogen tube, overcoat bobbin, pressure
End socket in plate, hot box, described alignment pin is inserted in the pin-and-hole of cold hydrogen mouth companion flange, and described cold hydrogen tube is by connecting ring with fixed
Position pin welding；Described hot box outside head by being welded with end socket in hot box by 1-4 thermal sleeve respectively, every two-layer every
Filling flexible graphite fibre rope between end socket in hot tank；Described overcoat bobbin welds with described pressing plate；End socket in described hot box
With stud welding, pressing plate is fixed in hot box on end socket by nut.
It is provided with pressure ring between described hot box and overcoat bobbin.
This utility model compared with prior art has the advantage that
1, this utility model uses alignment pin and is connected ring and cold hydrogen tube phase welded structure, and cold hydrogen mouth can be avoided corresponding
Flange welds mutually with cold hydrogen tube, such that it is able to reduce the space installed and required for dismounting, mounting structure lightweight, installs and tears open
Unload difficulty reduction, efficiency improves.
2, cold hydrogen tube is installed separately with cold hydrogen mouth companion flange and dismantles by this utility model, can be in maintenance and maintenance
Time, make the pipeline of destruction reduce, thus be substantially reduced maintenance and the maintenance cost in later stage.
3, during this utility model alignment pin is inserted into cold hydrogen mouth companion flange pin-and-hole, prevent cold hydrogen tube from running into flow at high speed
Cold hydrogen time produce strenuous vibration and rotation, prevent from causing the vibrations of pipeline and flange.
Accompanying drawing explanation
Explanation further details of to detailed description of the invention of the present utility model below in conjunction with the accompanying drawings.
Fig. 1 is structural representation of the present utility model.
Fig. 2 is partial enlarged drawing of the present utility model.
In figure: 1 alignment pin 2 connects ring 3 hot box outside head 4 flexible graphite fibres rope 5 collet
End socket in pipe 6 cold hydrogen tube 7 pressure ring 8 overcoat bobbin 9 pressing plate 10 stud 11 nut 12 hot box.
Detailed description of the invention
Such as the cold hydrogen mouth inner member of Fig. 1 and Fig. 2, it includes alignment pin 1, hot box outside head 3, cold hydrogen tube 6, overcoat bobbin
8, end socket 12 in pressing plate 9, hot box, alignment pin 1 is inserted in the pin-and-hole of cold hydrogen mouth companion flange, cold hydrogen tube 6 by connect ring 2 with
Alignment pin 1 welds；Described hot box outside head 3 is welded with end socket in hot box 12 by passing through 1-4 thermal sleeve 5 respectively,
Filling flexible graphite fibre rope 4 between end socket 12 in every two-layer hot box；Overcoat bobbin 8 welds with pressing plate 9；End socket in hot box
12 weld with stud 10, are fixed on by pressing plate 9 in hot box on end socket 12 by nut 11.Between hot box and overcoat bobbin 8
It is provided with pressure ring 7.
Before manufacture, testing each part material qualified, each part carries out blanking and processing by drawing, and according to
Product jointing technique is welded, and alignment pin 1 is manufactured by rod iron, and flexible graphite fibres rope 4 is outsourcing.
Carrying out dimension control after each part completion of processing, size should meet matching requirements, groove over right back clevis 2,
Groove over cold hydrogen tube 6, uses the welding procedure of bottom argon arc welding to weld, carries out outer surface polishing, beat after welding
Mill outer surface is concordant with mother metal so that it is do not affect the assembling of flexible graphite fibres rope 4.Then alignment pin 1 is inserted and connect ring 2
In endoporus, alignment pin 1 is welded with being connected ring 2, welding point surface of polishing so that it is concordant with being connected ring surface.
In hot box, end socket 12, hot box outside head 3 are assembled with thermal sleeve 5, and innermost layer thermal sleeve 5 is with heat insulation
Case outside head 3 phase is welded, filling flexible graphite fibre rope outside innermost layer thermal sleeve 5, intermediate layer thermal sleeve 5 and hot box
Interior end socket 12 and hot box outside head 3 phase welding, filling flexible graphite fibre rope outside intermediate layer thermal sleeve 5, outermost layer every
Thermal sleeve 5 welds with end socket in hot box 12 and hot box outside head 3 phase, and then stud 10 inserts end socket 12 in hot box
In endoporus, stud 10 is welded with end socket in hot box 12 phase.
Overcoat bobbin 8 assembles with pressing plate 9, is welded with pressing plate 9 by overcoat bobbin 8, and ensures to be connected with pressure ring
The planarity requirements of the plane connect.
