With reference to Fig. 6, strengthen structure 401 and formed by the first bearing assembly 410 and the second bearing assembly 470 that are positioned in two exposures that this tube panel is relative.(referring back to Fig. 3, the first bearing assembly 410 is parts of support column 400, and the second bearing assembly 470 is parts of support column 406.) each bearing assembly 410 comprises support column 420, horizontal flanges 430 and scalloped shaped rod 440.That support column 420 should be thought of as hollow and allow cooling fluid therefrom to pass.Horizontal flanges 430 is inwardly extended towards tube panel 210 from this support column.In horizontal flanges 430, there is groove 432.As shown, the horizontal flanges 430,472 on two bearing assemblies toward each other.Scalloped shaped rod 440 has the running surface and lip-deep lug 448 relative that engage tube panel 210.This scalloped shaped rod is by being connected to this support column through the pin 450 of lug 448 and groove 432.This scalloped shaped rod is by closely being kept (but unfixing) to screen pipe 460 through the pin 452 that is welded to the lug 454 on some screen pipe, and this scalloped shaped rod engages one or more screen pipes.Scalloped shaped rod 440 is remained on to the lug 448 that pipe 460 and the lug 454 of pin between 452 be connected to scalloped shaped rod 440 support column 420 relatively to be departed from.This allows screen pipe to carry out consistent thermal expansion with the bearing assembly that scalloped shaped rod is vertically independent of relative fixing (on vertical direction).Between the pipe of screen shown in protective sleeve 446 can be positioned at and scalloped shaped rod, avoid wearing and tearing and/or planing with protection tube in the time there is any relative motion (sliding-contact) between scalloped shaped rod and screen pipe.It should be noted in the discussion above that at this and described pair of flanges and lug 430,478, but on each bearing assembly, can have other flange and lug with prevent screen reverses and keep shield between alignment.Similarly, only show a scalloped shaped rod 440 that is attached to support column 420, but can use multiple scalloped shaped rods along this support column, with for example in the time that the vertical thermal expansion between the pipe in widescreen or between widescreen has large difference, strengthen on demand single wide widescreen or multiple widescreen.And each scalloped shaped rod 440 can have multiple lugs 448.This reinforcement structure can be supported by structure support frame (referring to Fig. 3).Support column can be attached or be connected to the vertical post of this bearing support, although these vertical posts are not shown in this way.
This reinforcement structure allows each pipe in tube panel to carry out independent thermal expansion, and allows reinforcement structure and support column to carry out independent thermal expansion.Pin/groove between scalloped shaped rod and support column is arranged and is allowed support column to carry out axial expansion to be independent of being radially expanded mode of pipe in tube panel.(noting: the axis of support column is perpendicular to the axis of the pipe in tube panel).
Above-mentioned supporting system allows each pipe 460 to arrange to have mode minimum aperture, each pipe tangent between each pipe.This has reduced the energy loss through the light in space, and has therefore increased heat absorption and the efficiency of receiver.Can see each pipe 460 at this, their middle part 462 is along the center line 405 of this tube panel.Also can consider the layout of this pipe to carry out other modification.
Referring now to Fig. 7, in certain embodiments, the diameter of the support column 420 of bearing assembly can be different from the diameter of arbitrary pipe 460 of tube panel, so that support column has extra stiffness, and in order to strengthen this screen, and hide the part being associated with this bearing assembly, reduce thus the operating temperature of part.In certain embodiments, the diameter 425 of support column is greater than the diameter 465 of arbitrary pipe 460 in tube panel.Support column 420 can think to have inner surface 422 and outer surface 424, and wherein, outer surface is exposed to from the flashing back the sunlight of heliostat.Can apply or paint the outer surface 424 of this support column to reduce/to minimize heat absorption and/or operating temperature.
With reference to Fig. 3, specifically can consider to strengthen at least three kinds of modification of structure.The first, the support column 400,406 that composition is strengthened structure 401,402 is connected to upper header 242 and lower collector pipe 250, makes them use the heat-transfer fluid same with the fluid-phase that flows through tube panel 210.But, can consider that support column uses other embodiment of different cooling fluids.This can be by being for example connected to each support column independently and realizing on collector.The second, provide bearing assembly at the support column 400 shown in this for strengthening structure 401,402.In other embodiments, strengthening structure can use independently support column to make.For example, support column can cross the first support height 225 and extend, and extends and but do not cross in the second support height 226; If desired, different support columns can be for the reinforcement structure at the second support height 226 places.The 3rd, as shown, strengthen structure 401 and use two independently support columns 400,406.Can conceive and only have a support column for strengthening other embodiment of structure.This can be for example realizes around the rectangle anchor ring (torus) of tube panel by support column is formed as.This single support column can provide the reinforcement structure 401 adjacent with the first surface shielding, and then wraps up the screen on equal height, and the reinforcement structure adjacent with another surface of shielding is provided.Also can realize by identical support column or different support columns at the second reinforcement structure height 402 places.
Also it should be noted in the discussion above that in Fig. 3, each support column is connected to upper header and the lower collector pipe of tube panel on the same side.For example support column 400 is connected to upper header 242 and lower collector pipe 250 along first side edge 216 simultaneously.Should be understood that, this can be different.For example, if only there is one to strengthen structure, support column 400 can be connected to upper header 242 along the first edge 216 so, then crosses first surface and is connected to lower collector pipe along second side edge 218.
Fig. 9 is the amplification front elevation of this tube panel, has wherein removed reinforcement structure.Generally speaking, tube panel 500 comprises multiple tube sides 510, shows four tube sides at this.Each tube side all comprises one or more pipes 512 parallel to each other.Pipe 512 between inlet header 514 and outlet header 516 by form from the sun the subject of knowledge and the object of knowledge body or the wall portion 537 that can be directed to heliostat, that focus on.Tube side 510 uses jumper pipe 502 to interconnect.Tube side 510 is organized at vertical direction or axially and makes heat-transfer fluid flow through tube side along replacing above-below direction, and this represents with arrow 505.This variation pattern on flow direction is called serpentine flow-channels (serpentine flow path) in this article.
This runner starts from entrance 504, and ends at outlet 506.It should be noted in the discussion above that if there is even number tube side 510, so can be along 508 or 504 location entrance 504 and the outlets 506 of the common edge of tube panel 500.Alternatively, if used odd number tube side, can in the opposite edges 508 or 544 of tube panel 500, locate so entrance 504 and outlet 506.In other words, need according to the design of receiver, entrance and exit is positioned at top 544 or bottom margin 508 places independently.As said, entrance 504 and outlet 506 all position along top 544.
Inlet header defines with respect to flow direction.Therefore, for tube side 530, collector 531 is considered inlet header, and collector 532 is considered outlet header.But for contiguous tube side 540, collector 542 is considered inlet header, and collector 541 is considered outlet header.The collector of tube side also can be designated as upper header 531,541,551,561 and lower collector pipe 532,542,552,562, and wherein upper header is positioned at the top of lower collector pipe.In other words, a set of collector 532,542,552,562 is positioned in lower plane 508, and another set of collector 531,541,551,561 is positioned in plane 544.
Refer again to tube side 530, pipe 536 forms body 537.Each pipe tight spacing and parallel to each other.Upper header 531 has width 533, and lower collector pipe 532 has width 534.In the embodiment of some considerations, and as shown, the width 538 of body 537 can be greater than the width 533,534 of collector.In other words, 5 37 of bodies can be wider than lower collector pipe 532 and upper header 531.Width is measured in the horizontal direction.The upper header of each tube panel is identical with the width of lower collector pipe.Ratio between the width of the width of body 537 and lower collector pipe and upper header 532,531 can be at least 1.01:1, and can be in 1.01 to 1.5 scope.This allows in interval between each edge pipe of adjacent tube panel and a tube panel tight spacing between each pipe identical.In such embodiments, the upper header of adjacent tube panel can be spaced in side direction.The lower collector pipe of adjacent tube panel also can be spaced in side direction.This can allow tube panel to carry out relative to each other expansion in various degree because operating temperature is different.
Figure 10 shows fluid and flows through the schematic diagram of dual exposed suction heat shielding 600.Start, upper draft tube 670 provides cold fluid in entrance container 660 from cold holding vessel 652, and for example, " cold " fused salt can be pumped from temperature is approximately the cold holding vessel of 550 °F.Inlet tube 672 is fluidly connected to tube panel entrance 674 by entrance container 660.In figure, also show the jumper pipe 696 between tube side.Outlet 678 is fluidly connected to exit vessel 662 by tube panel outlet 676.Heat-transfer fluid (HTF) can flow through tube panel 684 from entrance container 660 and arrive exit vessel 662.Lower draft tube 688 draws downwards and gets back to horizontal plane from exit vessel 662, and herein, " heat " fluid can flow in thermmal storage tank 650.
Entrance container 660 is selectable and dispensable, in figure, makes to be shown in broken lines, for example, if when heat-transfer fluid is steam/water.Outlet 678 and exit vessel 662 are also selectable and dispensable, and it is shown by dashed lines.If there is no exit vessel, heat-transfer fluid flows directly to lower draft tube 688 from tube panel outlet 676 by outlet 691.By-pass line 690 is also connected to lower draft tube 688 by upper draft tube 670.If needed, this bypass runner can stop heat-transfer fluid to flow through tube panel 684.
This has completed collection of energy process.Heat energy stored in heat-transfer fluid can be for generation of steam and electric energy.For example, this can be by realizing from 650 pumpings of thermmal storage tank hot heat-transfer fluid by the shell-side of heat exchanger 654.Water enters the pipe side of heat exchanger 654 and changes into steam.Steam can be sent to steam turbine 656, and steam turbine 656 drives generator 658.Then, leave heat-transfer fluid heat exchanger, colder and turn back in cold holding vessel 652, at this, this heat-transfer fluid is pumped into receiver to repeat above-mentioned collection of energy process.
For molten salt receiver, tube panel must be fully can discharge and can ventilate.While use when sunset or while having efficiency solar too low, this receiver is discharged conventionally.Fused salt solidifies in the time approaching the temperature of 430 °F (221 DEG C, 494 ° of K).If do not discharged, salt may condense in pipe, barrage reception device and may make tracheal rupture.As seen at this, solar receiver can comprise the breather valve 692 for each independent runner, and these breather valves are all ventilated by the top of lower draft tube 688.This breather valve is positioned near the top of lower draft tube 688 conventionally, and each runner is connected to lower draft tube by the ventilation line 694 also illustrating.Be generally every pair of tube side a bleed valve 697 is set, and bleed valve 697 is positioned at the below of tube side.Excretion pipeline 698 has also been illustrated, and is connected to lower draft tube 688, and the fused salt that makes to be present in tube panel is discharged from and flows into lower draft tube 688.Breather valve and bleed valve are automatically to control.
It should be noted that in Figure 10, shown in each pipe be relatively straight runner.But those of ordinary skill in the art should be understood that, their actual design in arrangement and length determine by adapting to solar receiver duration of work due to thermal expansion and shrink the required degree of flexibility of caused desired movement.Therefore, likely, other bending or length are necessary, to provide so flexible.
Only have the problem of traditional solar receiver arrangement of an exposure to be, if tube failure, in tube panel, only have so limited entrance can contact these pipes.Return with reference to Fig. 1, such solar receiver all has screen around 360 ° of supporting structures conventionally, and supporting structure only leaves a side for contacting this tube panel (i.e. inner side).In addition, with reference to Figure 1A and Figure 1B, the existence of insulation part and light barrier has increased and completes tube panel and repair needed maintenance time.Heat absorption screen in both sides of the present invention allows to have the maintenance access along top edge, lower limb and two lateral edges, provides thus around entrance 360 ° of these pipes, manage and insert new alternative pipe in order to remove inefficacy.In addition, at the pipe-pipe weld part in solar heat protection region (referring to Fig. 5) between collector and tube panel.Because welding repair material in new welding is than thickness of pipe wall, so this is necessary for reducing pipe temperature.
Tradition solar receiver uses the pipe-pipe butt welding between very thin pipe conventionally.Because being positioned at, new weldering/repair welding concentrates outside sunlight, so can use different joint for pipe.In Figure 11, can see such repairing joint for pipe.This repairing connector is easy to be more a lot of than welding in the time replacing inefficacy pipe.Show collector 750 at this, wherein extend from this collector from the pipe stump (tubing string) 760 of the collector of front pipe (lost efficacy pipe).Online 762 places of pipe stump of this front collector stop, and line 762 can cut at the scene according to the invalid position of original pipe.Aforementioned pipe stump be before the not inefficacy part of existing pipe.New alternative pipe 780 abuts to line 762 places of on-site cutting.Repair welding joint for pipe 770, in order to hold the end of this pipe stump and alternative pipe, is similar to two pipes is inserted to cylindrical sleeve.Then can use Site Welding that amendment joint for pipe 770 is attached to respectively to pipe stump 760 and substitute pipe 780 (as used fillet welding).This repairing joint for pipe 770 is positioned at heat cover rear portion, and is not exposed to the sunlight from heliostat.
Tube panel can be strengthened with the different device of the reinforcement structure such as seeing from Fig. 6 to Fig. 8.Another reinforcement structure can be positioned in the heat cover protection zone of heat absorption screen.This is shown in Figure 12.There is collector stump 720 in the lower collector pipe 250 shown in this.This collector stump 720 has external diameter 722 and internal diameter 724.In figure, also show the wall pipe 700 in tube panel.This pipe has external diameter 712 and internal diameter 714.The internal diameter 724 of pipe stump 720 is identical with the internal diameter 714 of pipe 710.But the external diameter 722 of pipe stump is greater than the external diameter 712 of pipe 710.In other words, the thickness 707 of the wall of pipe stump 720 is greater than the thickness 705 of pipe 710.Use fillet welding that pipe stump 720 and pipe 710 are welded together.Rephrase the statement, they have discontinuous change on thickness.Heavier and thicker wall pipe can increase the rigidity of the tube panel between upper header and lower collector pipe, allows tube panel to have longer light exposed region.In addition, any supporting fixture or weld part all may be because pipe be compared with thick and more greatly and more firm.
Figure 13 shows the design of interchangeable heat cover.In Fig. 4, the lateral edges 216,218 of the inward flange 342 butt tube panels of heat cover 340.At this, between the lateral edges 216,218 of tube panel and the inward flange 342 of heat cover, there is space and open spaces 201.This open spaces causes freestanding tube panel.This arrangement allows heliostat to focus on more equably on the whole width of tube panel, and this generally needs some heliostats towards tube panel edge focusing.This open spaces provides to reduce concentrates sunlight to spill into the buffering on heat cover.Alternatively, concentrated sunlight can pass this open spaces, although this may be considered to be energy loss.In more detail, the inward flange 342 of heat cover comprises top edge 344, lower limb 346, first side edge 348 and second side edge 350.Between the inside edge 216,218 of this heat cover and the lateral edges 348,350 of tube panel, have open spaces 201.In specific embodiment, the width of this open spaces is at least 1% of tube panel width.At this, support column 400 and 406 is also visible.
Another imagination of design solar receiver is such scheme, and heat-transfer fluid (HTF) is because the pump that for example loses Factory Electricity Supply or lose for heat-transfer fluid being moved through to solar receiver stops flowing through tube panel.In this scheme, heliostat still all focuses on the tube panel of this solar receiver.Heliostat can not defocus immediately, and owing to there is no heat transfer fluid flow, higher heat flux can make tube panel overheated rapidly.
The existing solar receiver moving between year April in January, 1998 to 1999, be known as " No. two, solar energy " (Solar Two), entrance and exit heat-transfer fluid container is as buffer.Entrance container is oppressed by the compressed air with sufficiently high pressure, constantly the heat-transfer fluid that is included in entrance container is flow through to sufficiently long tube panel, allows thus heliostat out-focus on this receiver.
Figure 14 and Figure 15 have described the another kind of arrangement that solar receiver of the present invention design is allowed.At this, heat cover 340 comprises upper surface 352, the first side 354 and the second side 356.And, in heat cover, have window or hole 355, by this window or hole 355, can see tube panel 210.Shielding curtain 750 is positioned at the outside of the first heat cover upper surface 352 of tube panel 210 tops.At this, this shielding curtain is rolled-up in reserve position.This shielding curtain can be made up of the exotic material such as such as enamel coating.Be positioned in order to guide the device 752 of this shielding curtain on first side 354 and the second side 356 of this heat cover.As Figure 15 sees, shielding curtain also can be positioned at the second side on the second heat cover 360.In Figure 14, support column 400 and 406 is also visible.
If there is trip condition, shielding curtain can be released so, and falls to stop the concentrated sunlight from heliostat in tube panel front.It is overheated that this can protect tube panel to avoid, until heliostat out-focus in this receiver, has been eliminated necessity of entrance container thus.A beneficial effect of this solar receiver design is can guide energetically the edge of this shielding curtain with this shielding curtain of leaving behind, and keeps this shielding curtain not to be subject to the impact of wind, and wind may be opened some part of tube panel.At this, this shielding curtain can extend to outside the width of tube panel.Therefore, can be for example guide by guide rail (as the door of storehouse) or with guiding cable at the edge of this shielding curtain.At this, shown in guiding device be the track 758 covering by heat, and with the cable that is attached to this shielding curtain.This also protects the member for the shielding curtain of leaving behind above tube panel.For example, the bottom margin of this shielding curtain can increase the weight of.Alternatively, cable can be in order to the shielding curtain of leaving behind from sidepiece.
Figure 16 shows the front view that puts down shielding curtain.This shown shielding curtain 750 is being put down only about half of.The bottom margin of this shielding curtain is (Reference numeral is 754) of increasing the weight of.Guiding cable 756 extends along cable track 758, and is attached to the base angle place of this shielding curtain.
With reference to exemplary embodiment, the present invention is described.Significantly, reading and understanding after previous embodiment, other people can modify and change.If be intended that in the scope that these amendments and variation drop on claims or equivalents, the present invention is understood to include all such modifications and variation so.
