Embodiment
Describe the present invention in detail below in conjunction with accompanying drawing.
MHTR pressure vessel of the present invention comprises by hot gas conduit 6 interconnective reactor vessel 1 and steam generator pressure vessels 7.The undamped device supporting system of MHTR pressure vessel of the present invention comprises the coupled reaction heap pressure vessel 1 that is arranged on the hot gas conduit 6 axis height and the first main load-bearing supporting 4 of biological shield 8, rotates and axial displacement in order to prevent reactor vessel 1; Be arranged on the second main load-bearing supporting 3 of connection steam generator 7 pressure vessels on the hot gas conduit 6 axis height and biological shield 8, axial displacements take place in order to prevent steam generator pressure vessel 7; Be arranged on the coupled reaction heap pressure vessel 1 on reactor vessel 1 top and first lateral-supporting 2 of biological shield 8, circumferentially rotate in order to prevent reactor vessel 1; And be separately positioned on the connection steam generator pressure vessel 7 of steam generator pressure vessel 7 upper and lowers and second lateral-supporting 5 of biological shield 8, circumferentially rotate in order to prevent steam generator pressure vessel 7.
As depicted in figs. 1 and 2, the first main load-bearing is supported 4 hoops and is distributed on reactor vessel 1 outside, has four.The second main load-bearing is supported 3 hoops and is distributed on steam generator pressure vessel 7 outsides, has four.Four the first main load-bearing supportings 4 in reactor vessel 1 outside also are positioned on the biological shield (being the biological shielding cement wall) on every side by the bolt of side direction respectively, they can play the centralized positioning effect to reactor vessel 1, and prevent that rotating and axial displacement from appearring in pressure vessel, but the authorized pressure shell there is free thermal expansion radially.Four second 3 of main load-bearing supportings of steam generator pressure vessel 5 are only limited in each supporting place and axial displacement do not occur, but allow the displacement of horizontal direction, thereby make pressure vessel thermal expansion freely, but axial displacement can not be arranged.
The of the present invention first main load-bearing supporting is identical with the second main load-bearing supporting structure, and existing is a kind of embodiment that example describes the load-bearing supporting in detail with the first main load-bearing supporting.As shown in Figure 3 and Figure 4, the concrete structure of first main load-bearing supporting is: pressure vessel welding plate 9 is welded on pressure vessel 1 outer wall, and also on the welding pressure shell, simultaneously vertical lacing wire 18 welds together with pressure vessel welding plate 9 in its upper vertical lacing wire 18.Lower end, pressure vessel welding plate 9 outside is supported on upper guide on dull and stereotyped 10, and upper guide is provided with groove to dull and stereotyped 10 surfaces, and authorized pressure shell welding plate 9 produces relative displacement therein.Upper guide welds together by excessive frid 11 and excessive guide plate 12 to flat board 10, and like this, upper guide can be used as a mass motion to flat board 10, excessive frid 11 and excessive guide plate 12.Excessively guide plate 12 lower support are on biological shield flat board 13.Dull and stereotyped 13 surfaces of biological shield are provided with chute, allow excessive guide plate 12 to produce relative displacement.Biological shield flat board 13 is welded on the biological shield riser 14, and the bottom has vertical support plate 17 and biological shield flat board 13 to weld together, and biological shield flat board 13 is played a supportive role, and vertical support plate 17 also is welded on the biological shield 8 simultaneously.Biological shield riser 14 is fixed on the biological shield 8 by first set bolt 15 and first hold-down nut 16.
According to the difference on reactor vessel and steam generator pressure vessel weight, the height, the lateral-supporting of two shells also to be treated with a certain discrimination, the lateral-supporting quantity of two pressure vessels is slightly different.
As depicted in figs. 1 and 2, on the wall of reactor vessel 1 top outside, be provided with four first lateral-supportings 2, supporting-point allow along pressure vessel radially with axial displacement, but do not allow supporting-point to have along the circumferential rotation displacement of pressure vessel.The thermal expansion of pressure vessel is not limited, but the horizontal shift of pressure vessel and rotation then are completely restricted.Like this, the effect that reactor vessel has played antidetonation supporting and load-bearing supporting of honouring is propped up in first lateral-supporting and the first main load-bearing.
Be provided with 5, two second lateral-supportings 5 of three second lateral-supportings altogether in the top and the bottom of steam generator pressure vessel 7 on steam generator pressure vessel 7 tops, a lateral-supporting 5 is in steam generator pressure vessel 7 bottoms.Second lateral-supporting, 5 restriction steam generator pressure vessels 7 are in the horizontal shift perpendicular to hot gas conduit 6 axis directions, can bear the horizontal seismic force of this direction, four second 3 of main load-bearing supportings have limited rocking of seimic steam generator pressure vessel 7, make whole steam generator pressure vessel 7 have function of seismic resistance.
First lateral-supporting of the present invention is identical with the second lateral-supporting structure, and existing is a kind of embodiment that example describes lateral-supporting in detail with first lateral-supporting.As shown in Figure 5 and Figure 6, the concrete structure of described first lateral-supporting is: the horizontal hanger 19 that is welded on the end fluting on the pressure vessel outer wall; The left-handed pivoted frame 23 and the dextrorotation pivoted frame 24 that are linked together by straight pin 21 and horizontal hanger 19, the other end of left-handed pivoted frame 23 and dextrorotation pivoted frame 24 also has through hole, be provided with convex axle 27 in the through hole, two swivel mounts connect with swivel mount bearing 30 by convex axle 27 respectively, and swivel mount bearing 30 is fixed on the biological shield 8 by Bolt Connection; Be enclosed within straight pin 21 tops and be embedded in left-handed pivoted frame 23 and dextrorotation pivoted frame 24 in inside upper part sleeve 22, make two swivel mounts more flexible with respect to the rotation of horizontal hanger 19; Be enclosed within the middle of the straight pin 21 and be embedded in inboard intermediate sleeve 20 in the horizontal hanger 19, make the rotation of horizontal hanger 19 more flexible; Be enclosed within convex axle 27 tops and be embedded in outer upper sleeve 28 in the swivel mount bearing 30, make two swivel mounts more flexible with respect to the rotation of convex axle 27; Be enclosed within the middle of the convex axle 27 and be embedded in left-handed pivoted frame 23 or dextrorotation pivoted frame 24 in outer middle side part sleeve 29, make two swivel mounts more flexible with respect to the rotation of convex axle 27.Left-handed in this example pivoted frame 23 and dextrorotation pivoted frame 24 distribute at an angle of 90.
Lateral-supporting of the present invention all connects by bolt and on every side biological shield (being the biological shielding cement wall), and the weight and the seismic (seismal of pressure vessel is delivered to biological shield.
The present invention not only can be used for MHTR pressure boundary parts, can also use in the supporting of other large pressurized vessel, such as refining equipment of petrochemical plant etc.Use the present invention can guarantee effective supporting of equipment, guarantee the anti-seismic performance of equipment, and reduce manufacturing expense.
