The invention relates to a device for receiving hot, corrosive liquids (7), comprising a chamber enclosed by a wall (21) for receiving the liquid (7), wherein the chamber comprises an interior insulation (19). The invention further relates to a use of the device for storing corrosive liquids for storing a heat storage medium comprising sulfur.
Description
Technical field
The present invention is based on a kind of for holding the device of hot corrosivity active liquid, it comprise by wall, impaled for holding the space of described liquid.In addition, the invention still further relates to the purposes of this device.
Background technology
For the device that holds hot corrosivity active liquid, be for example tank, it is for holding the hot storage medium of solar power plant.In solar power plant, as long as there is by day solar radiation just by solar energy, to produce heat.With this heat, generate electricity.Usually, with this heat, by the water evaporation and by the steam drive generator produced, generate electricity.
For solar power plant can be operated constantly, by solar energy, hot storage medium is heated.This hot storage medium leaves in the tank that effect of heat insulation is good.In order to extract heat, for example, when sunlight no longer irradiates, the hot storage medium of heating is removed and for for example water being evaporated.Hot storage medium thereby release heat and be cooled.Then for example make cold hot storage medium enter the second tank for cold hot storage medium.In order can interruptedly not operate in solar power plant, large solar power plant needs very large hot memory.
For the water by solar power plant evaporation and by Steam Heating to being suitable for the temperature operated, hot storage medium need to be heated to corresponding high temperature.At present, the hot memory in solar power plant operates with the operating temperature in scope between 290 and 390 ° of C.In addition, current trial expands to 550 ° of C by this temperature range, or even arrives the above temperature of this temperature.
For example fused salt is used as to hot storage medium.The solar power plant large due to operation needs a large amount of hot storage mediums, therefore also seeking substitute here.The hot storage medium substituted is also for example the hot storage medium of those sulfur-bearings.At fused salt with in the situation that the hot storage medium of sulfur-bearing at high temperature can produce corrosion on the tank usually be formed from steel.For example, the nitrate of some fusings can cause various high-grade steel embrittlement at 550 ° of temperature more than C.Although high-grade steel is stable, they are for impact sensitive.In the situation that the storage medium that contains a large amount of sulphur, the sulphur that for example contains the potassium sulfide of 1% percentage by weight, significantly corrosion occurs at 350 ° of temperature more than C, when this temperature is elevated to the seepage failure fast that 400 ° of C cause typical iron-based and Ni-based high-grade steel when above.Contain muriatic fused salt and be also at high temperature easy high corrosion.At lower temperature, corrode quite less, even there is in some cases corrosion.
The material that even at high temperature also can withstand corrosive substance is for example pottery and glass.Yet these materials are not in the situation that have seal generally can not be joined together to form large structure, such as the structure for hot storage tank necessity.The encapsulant used at high temperature can suffer the corrosivity infringement.In addition, these materials are generally frangible, and can not bear high internal pressure when being joined together to form structure.
Summary of the invention
Therefore, the purpose of this invention is to provide a kind of for holding the device of hot corrosivity active liquid, its be erosion-resisting and be the sealing, there is enough mechanical stabilities can hold even a large amount of liquid simultaneously.
This purpose is to reach for the device that holds hot corrosivity active liquid by a kind of, this device comprise by wall, impaled for holding the space of described liquid, described space has the internal insulation element.
In this kind of situation, the internal insulation element can directly be put or can between internal insulation element and described wall, be formed with gap against the wall cloth of tank.
The internal insulation element has avoided the liquid that is included in the heat in described space to contact with described wall.Due to the isolation effect of internal insulation element, in the face of the temperature of the side of described wall significantly lower than the temperature of hot liquid.This has realized the temperature that defines the described wall in described space to be remained on the following effect of temperature of corrosion.
In order to prevent that the internal insulation element from bearing the effect power be not allowed to thereon, while especially when the internal insulation element and between inside keeps the wall in described space of described liquid, having gap, described internal insulation element preferably has the passage that described liquid can flow through.As a result, set up pressure balance on the outside of the inboard of isolated component and isolated component.Therefore, described internal insulation element is about needing not be stable from inboard applied pressure.If the gap between especially described internal insulation element and described wall is inhomogeneous or put and form in the localities gap at some against described wall cloth at some local described internal insulation elements, liquid flows through described passage and enters described gap until set up pressure balance.This has been avoided causing the distortion of the internal insulation element that destroys.
These passages are designed so that liquid can flow into these passages and still not have convection current to occur in this case.This makes liquid to flow out from tank by these passages, once but, after these passages are filled, mass transport just not occur in these passages.Especially when the liquid that will store has low heat conductivity, for example, in the situation that molten sulfur, the liquid be included in these passages also has effect of heat insulation.Although described liquid is owing to contacting with the wall in described space by these passages, but it has the temperature lower than the liquid in memory, the thickness of isolated component be chosen to make the temperature in the zone of described wall so low so that corrosion occur, or minimum corrosion is at least only arranged.
In order to compensate the different thermal expansion of described internal insulation element and the material of the described wall that impales described space, preferably, described internal insulation element has dilatation joint.And described dilatation joint is preferably to be sized to make in them convection current does not occur equally.In a preferred embodiment, be used as dilatation joint for pressure balanced passage in the internal insulation element simultaneously, it destroys the internal insulation element for preventing thermal expansion.Like this, even can sustain the load caused by temperature change and not destroy the internal insulation element.
Here, the size of described passage and/or dilatation joint depends on the stickiness of the liquid comprised in described space.
Even for example, in the situation that the perforate fireproof insulation brick (can with its production internal insulation element), although penetrate the heat-proof quality that liquid in hole has reduced insulating brick, the low heat conductivity of liquid (for example sulphur) is enough to form enough strong effect of heat insulation.
Described internal insulation element for example can consist of the element that is substantially rectangle.Substantially be that the element of rectangle also comprises that width outwards increases so that the element of tank and circular cross section coupling, thereby the dilatation joint between these elements has uniform width, and comprise the element mated with the tank diameter with the circular segment form design.Described passage or dilatation joint are for example the gaps between rectangular element.Can further prevent convection current by the rectangular element of in a row placing to form the internal insulation element in the dislocation mode.Now, the gap between two rectangular element is only high as this rectangular element in each case, and is interrupted by the rectangular element of next row.
Described internal insulation element can be both from supporting, also can form by isolated component being fastened to described wall.In the situation that the isolated component certainly supported, isolated component for example in a row places to form inwall, and this wall can be described wall self-supporting or that can lean on described space.If the internal insulation element of supporting has dilatation joint certainly, is especially favourable.
In order further to improve isolation, between described wall and described internal insulation element, can form the second separation layer.This second separation layer can be formed by the material identical with described internal insulation element in this kind of situation.Can also use two kinds of different materials.
If comprise the second separation layer between described wall and described internal insulation element, for example described internal insulation element (preferably from supporting type) can be formed by abrasion-resistant material, for example alumina firebrick, and this second separation layer comprises height heat-barrier material, for example foam glass.
Described internal insulation element can also be to form more than two-layer structure.In this case, at least one deck preferably from the supporting the internal insulation element, and other layers can be or can not be from the supporting.Certainly the supporting separation layer that for example can also replace with multi-ply construction and height heat-barrier material.Yet in addition, can also make all separation layers is all from supporting.
If especially described the second separation layer is not from supporting, advantageously, it is retrained by the internal insulation element of supporting certainly on inboard and on the outside.Yet preferably, every layer of isolated component is from supporting.
In a preferred embodiment, comprise the seal of resistant material between described internal insulation element and described wall.The seal of this resistant material can be for example liner, is for example the form of corrugated metal sheet.The use of the seal of resistant material makes described wall can use non-resistant material.Resistant material (for example corrosion resistant high-grade steel) is generally expensive, and to have than the liquid about comprising in described space be not the intensity level that corrosion resistant steel is lower.It can not be that stable steel is produced the described wall in the described space impaled (for example tank) by the liquid about comprising in described space that the use of the seal of resistant material makes.The seal of resistant material helps avoid the liquid comprised in described space and contacts with described wall.
For the device of depositing hot corrosivity active liquid, it is for example tank.It generally has wall and lid, thereby forms the enclosure space that wherein comprises hot corrosivity active liquid.The wall of described tank for example can be made by construct typical material for tank, for example steel or high-grade steel.If especially use the seal of resistant material, can also to use the liquid about comprising in described tank be non-corrosion-resistant material to the described wall of described tank.
The suitable resistant material that can produce described seal is for example graphite or aluminium.
If be tank for the device of depositing hot corrosivity active liquid, it is sealed by cover usually.Now, on described cover, isolated component is set equally.The isolated component of described cover has also been avoided in the zone of cover, and---especially when described tank is filled up fully---described cover contacts with the corrosivity active liquid of described heat.In addition, also avoided around heat is discharged into via cover.
Except tank, the parking space impaled by wall can also be the chamber in ground.In this case, described chamber can be the nature chamber on the one hand, alternatively, can also for example form artificial chamber simultaneously.The advantage of the chamber in ground is to realize the larger height of memory, because it can stand the hydrostatic pressure higher than traditional tank---because the power produced on described wall due to hydrostatic pressure is absorbed by ground.The large height in described space is particularly suitable for being included in corrosivity active liquid in described space and is intended to as the hot memory of thermocline memory (Schichtenspeicher, thermocline reservoir) operation in any case.In the hot memory as the thermocline storage operation, there is cold liquid in bottom, there is hot liquid at top.Large height has increased the time of transmitting equilibrium temperature by heat.Can realize so very large hot memory (for example, for solar power plant), it for example can be used as sky, week and can be used as in principle the moon or or even year memory.Due to the fluctuation of natural energy resources (such as wind and the sun), therefore, this is especially helpful.
Another advantage of chamber in ground is, for the hot memory of solar power plant, can also under pressure and under the maximum temperature apparently higher than 440 ° of C, operate, because even can apply the system pressure more than 1 bar in the situation of large memories.Another advantage is, the corrosivity active liquid of heat can be in the situation that in the chamber of deaeration in remaining on ground, thereby greatly reduces the risk of fire.
Material or product that the internal insulation element of the chamber in ground has avoided hot corrosivity active liquid to contact with ground and react and carry secretly release from the ground h substance or with them.The material discharged from ground or product for example can or stay deposit by the other element at equipment by the corrosivity that increases and damage---and described equipment is the equipment that uses the device for depositing hot corrosivity active liquid.
Chamber in ground can be for example that side is formed by artificial fully on the ground, for example by artificial foundation, is formed with the hill of this chamber.In addition, the chamber in ground can be partly at below ground, and it both can use the chamber by self-assembling formation also can use artificial chamber.Described chamber can also be fully in underground formation.In this case, especially use the nature chamber.According to the present invention, the internal insulation element is introduced in the chamber in ground.Just as described above, this internal insulation element be particularly useful for avoiding leaving in liquid in described chamber from the ground h substance or with the substance reaction that comes from ground.
Aluminium oxide, carborundum, silica, foamed aluminium, foam glass or their mixture are suitable for example as the material of internal insulation element, both can be used in tank and also can be used in the chamber in ground.A plurality of layers can also be provided, and these layers can be made by different materials.
For example, if be especially tank, the tank that especially there is metallic walls (steel wall) for the device of depositing hot corrosivity active liquid, although the internal insulation element is arranged, tank skin for example, still likely in can damage at the temperature of (when contact).In this case, preferably, described tank skin is in addition by the external isolation element encompasses.What be suitable for the external isolation element is for example mineral fibres felt or standard foam glass plate.For example, in the situation that other covered metal plate (zine plate) can avoid moisture to invade isolated component.
For example, according to the hot storage medium that is particularly suitable for holding solar power plant (parabolic trough type solar power plant) for the device that holds hot corrosivity active liquid of the present invention.Operable hot storage medium is for example fused salt or the hot storage medium of sulfur-bearing.What especially be suitable as the hot storage medium of sulfur-bearing is elemental sulfur.In order to adapt to steam pressure and melting pressure, it is favourable that at least one anion-containing additive is added in sulphur.

Thermocline memory 1 comprises tank 3, and it is formed by for example metal material (such as steel) structure.For this reason, tank skin 5 is made by metal material, and it is mechanically stable about the pressure produced in tank that the wall thickness of tank skin 5 is chosen to make it.The hydrostatic pressure of the downward increase that is included in the liquid 7 in tank that especially will consider here.Described tank 3 is by cover 9 sealings.In addition, another cover 11 can be set, when tank 3 fills up fully, it only leans against on the liquid 7 be included in tank 3, thereby does not have gas to be included in tank 3.In order to compensate the fluctuation of liquid level, compensatory zone 13 can be arranged on described another lid 11.These compensatory zones for example can the ripply form of tool.Described compensatory zone 13 makes described another lid 11 shape for example by welding procedure, be connected to described tank skin 5 in locking manner.This makes it possible to achieve and is tightly connected.When existing liquid level rising or liquid level to reduce, described another lid 11 raises or reduces, thereby it is always so that the mode that does not have gas to be included in described tank is sealed described tank.Alternatively or in addition, can also or remove the change that liquid (for example, from surge tank) compensates the volume of storage medium when the variations in temperature by supply.
If, as thermocline memory 1, there is the first distributor 15 in described tank 3 in the upper area of described tank 3.The liquid of heat can be fed in described tank equably by described the first distributor 15.In order to keep liquid level constant in tank, the second distributor 17 of locating by tank 3 bottoms removes colder liquid simultaneously.Cold liquid is removed equably by the first distributor 15 and the second distributor 17, thereby preferably do not have convection current to occur, thus and the very little vertical thermal transmission of generation in tank.Like this, can be by liquid storage in tank, make generally to there is more highdensity colder liquid and be included in lower area, and have, more low-densityly than geothermal liquid, be included in upper area.In ideal conditions, the liquid in tank has two temperature, that is, and and the higher temperature in upper area and the lower temperature in lower area.Formation temperature boundary layer between hot zone and cold zone.Due to the heat transmission that can not avoid in liquid, therefore under actual conditions, between the liquid of H/C, can not there is boundary line clearly, but form the temperature transition from hot liquid to colder liquid.Due to the heat transmission, to deposit lastingly that the time is longer, transition is just more and more not obvious.
In solar power plant, when utilizing solar energy will be as the heating liquid of hot storage medium the time, by the hot liquid of the first distributor 15 supply, by the second distributor 17, remove colder liquid.If do not shine upon, but in solar power plant, continue generating, with regard to the heat with leaving in hot storage medium, water be evaporated to drive the turbine of generator.For this reason, remove the hot storage medium of heat from described tank 3 by the first distributor 15, reject heat in heat exchanger, water as operating fluid is evaporated and superheat in described heat exchanger, then by the second distributor 17 in the lower area of described tank, cold hot storage medium is returned.By from described tank 3, remove heat hot storage medium and by during heating removing cold hot storage medium, in each case, the temperature boundary layer in tank 3 all shifts.Between the period of heating of hot storage medium,, when by the first distributor 15, supplying the hot storage medium of heat and removing colder liquid by the second distributor 7, temperature boundary layer shifts downwards, and, when use is stored in the heat in liquid 7, temperature boundary layer upwards shifts---the amount increase of the cold hot storage medium that heat has been used because the amount of the hot storage medium of the heat in described tank 3 reduces.
With the liquid 7 that acts on hot storage medium, are for example the hot storage mediums of fused salt or sulfur-bearing.What especially be suitable as the hot storage medium of sulfur-bearing is elemental sulfur, yet it may be contaminated or comprises other additive.Fused salt and the sulphur material about iron content or nickel at relative high temperature is all highly corrosives.For example, the nitrate of melting makes high-grade steel embrittlement at 550 ° of temperature more than C.Although high-grade steel is stable, they are to impact sensitive.The hot storage medium of sulfur-bearing (sulphur that for example has 1% potassium sulfide) produces significant corrosion at 350 ° of temperature more than C on typical iron/nickel high-grade steel, causes high-grade steel seepage failure at short notice when 550 ° of C increase when temperature.
The fused salt of chloride is also at high temperature high corrosion.
In order to prevent corrosion, according to the present invention, comprise internal insulation element 19 in tank 3.The liquid 7 that internal insulation element 19 has been avoided being included in tank 3 contacts with the wall 21 of the spatial accommodation that surrounds liquid 7.In addition, due to this isolated component, the temperature on wall 21 is significantly lower than the temperature of liquid 7 in tank 3.
Figure 2 illustrates the example of the structure of internal insulation element 19.As shown in figure 2, it is from supporting.For this reason, be the element of rectangle substantially or can also be to arrange with two misarrangement positions for trapezoidal element 23 or other elements 23 of circular segment form a little for the sphering profile corresponding to tank in case of necessity.There is gap 25 between every two rectangular element 23 of a row.Gap 25 is for the different thermal expansion of the material that compensates internal insulation element 19 and tank skin 5.In order to form internal insulation element just as shown in Figure 2, rectangular element 23 layered arrangement in a row one above the other, rectangular element 23 stacked on top of each other is preferred about dislocation layout each other.The effect of the geometrical length with restriction gap 25 is arranged in dislocation.In addition, gap 25 is sized to and makes that there is no convection current be preferred.Although liquid 7 can flow in gap 25, once liquid 7 just should be avoided the constant mass transport in gap by gap-fill.Especially in the situation that the bad liquid of heat transfer effect, in the situation of utilizing molten sulfur, the liquid be included in gap 25 also has effect of heat insulation.The row's of two dislocation design has avoided liquid to arrive wall 21 by internal insulation element 19 as shown in Figure 2.
In a substituting embodiment, the internal insulation element can also consist of row's rectangular element 23.In this case, liquid arrives wall 21 by gap 25.Due to the isolation effect of isolated component 19 and because gap 25 is designed so that not have convection current, occur, therefore, the temperature that flows through the liquid in gap 25 also reduces, thereby the temperature of the liquid contacted with wall 21 is lower than the temperature of liquid 7 in tank 3.The thickness of isolated component 19 is chosen to make the temperature by the liquid 25 in gap to be in this kind of situation: at liquid, the material to wall 21 has below the temperature of high corrosion effect this temperature.
Figure 3 illustrates the example of the structure of the internal insulation element formed by division board.Different as the embodiment of the internal insulation element 19 from shown in Fig. 2, be illustrated in internal insulation element 19 right and wrong in Fig. 3 from supporting.This internal insulation element 19 comprises the independent division board 27 be arranged on wall 21.It is stable about the power (for example, due to the hydrodynamic that is included in the liquid in tank) acted on thereon that the thickness that forms the wall 21 of tank skin 5 is chosen to make wall 21.
For described isolated component is provided, described division board 27 for example is fastened to described wall 21 by suitable wall hook 29.Use the advantage of wall hook 29 to be, the independent division board 27 of internal insulation element 19 can be installed with plain mode, and if need, can also again pull down.Yet, except fastening with wall hook 29, can also division board 27 be fastened to described wall 21 well known to a person skilled in the art any other desired way.For example, can division board be connected to described wall 21 by bonding mode.Yet this shortcoming had is no longer may easily they be pulled down.
In order to compensate stress, occur, described division board 27 also is mounted to and forms gap 25 between every two division board 27.In embodiment shown in Figure 3, the size in gap 25 also should be chosen to make does not have convection current to occur in gap 25.As a result, during filling, gap 25 is by the liquid filling flowed into, and still, then this liquid stayed in gap 25, thereby and equally for providing heat insulation.Because division board 26 is generally not concordant with wall 21, therefore, liquid also flows to division board 27 back.Yet the isolated component with division board 27 has such effect, that is, make the liquid contacted with wall 21 be cooled to and make it no longer there is the degree of corrosiveness on wall 21.
In order to prevent division board 27 corrosion, they can additionally be provided with anticorrosive coating 31.Here suitable is to well known to a person skilled in the art any coating as anticorrosive coating.Suitable coating is for example coating or the Al of glazing
2o
3coating.
The coating 31 of division board 27 is particularly suitable for will be about the unsettled material of liquid 7 in being included in tank as the material of division board 27 in any case.
A kind of feasible configurations of the cover with isolated component has been shown in Fig. 4.
The structure for cover shown in Fig. 4 correspond essentially to shown in Fig. 3 above the tank skin structure of division board is installed.
In order to ensure also being isolated, isolated component 35 is set on cover 33 on upward direction.Similar with the mode shown in Fig. 3, for example can be by means of the fastening isolated component 35 of hook 37.Yet, for example be threaded connection or the fastening of binding agent bonding is also feasible.The material used and will leave the liquid 7 in tank according to isolated component 35, apply anticorrosive coating 31 can to isolated component 35.If form gap 25 between independent isolated component 35, the different thermal expansion that can compensate the material of the isolated material of isolated component 35 and cover 33 on cover 33 is also preferred.
Figure 5 illustrates the tank skin structure had from the internal insulation element of supporting.
Anticorrosive seal 39 on inboard with the first separation layer 41 adjacency.Described the first separation layer 41 preferably from supporting and by the rectangular element of stratification stacked on top of each other, formed.If form gap between the independent rectangular element of the first separation layer 41, be favourable, as for example also shown in figure 2.Described the first separation layer 41 is for example highly heat insulation material.Result has obtained good heat insulation.The first separation layer 41 and the second separation layer 43 adjacency.The second separation layer 43 is for example made by abrasion-resistant material, thereby also is particularly useful for the purpose that internal insulation element 19 is not destroyed by the motion of liquid in tank.The second separation layer 43 also preferably from the supporting and for example with rectangular element the layer arranged in form.Here, if form gap also between the independent element of the second separation layer 43, be favourable, with the different thermal expansion of the material that can compensate the first separation layer 41, the second separation layer 43 and tank skin 5.
Liquid can flow through the gap 25 between the independent element of the first separation layer 41 and the second separation layer 43 on the direction of wall 21.Then liquid is assembled at anticorrosive seal 39 places.Due to pressure balance, on the every side in the both sides of isolated component 19, all exist the fact of the liquid of uniform pressure to avoid acting on isolated component 19 and from outside, do not obtain the generation of the high internal pressure of compensation.This has been avoided the distortion of internal insulation element 19 greatly.
Although there is internal insulation element 19, can be so high due to the temperature at tank skin 5 places so that there is risk that injury occurs (if for example contact tank skin 5), therefore, tank skin 5 can also be on the outside and external isolation element 45 adjacency.External isolation element 45 for example can consist of traditional heat-barrier material, for example mineral fibres or glass fibre.In order to make tank not be subject to weather effect, then for example with metallic plate 47, external isolation element 45 is covered.The metallic plate 47 used is for example commercial commercially available zine plate, and it is weather resistance especially.
In Fig. 6, with the form of the chamber in ground, show for holding the device of hot corrosivity active liquid.
Different as the structure from shown in Fig. 1-5, alternatively, can also be designed to the device for holding hot corrosivity active liquid ground 51 middle chambers 49.The advantage of doing like this comprises, the ladle bowl of tank skin 5 forms that need to be unstable about high pressure.The power acted on wall 21 is absorbed by ground 51.This device can be for example the thermocline memory equally.If the device for receiving fluids is the thermocline memory, in upper area, arrange first and enter head piece 53, hot hot storage medium can be fed in chamber 49 or from chamber 49 to be removed, and arrange second and enter head piece 55, lead in the lower area of chamber 49 and cold hot storage medium can be removed or feed.Function is corresponding to the thermocline memory shown in Fig. 1.
Different as the thermocline memory from the tank form, in the situation that the chamber 49 in ground 51 can be realized the sizable height of memory.As a result, can reduce diameter for the hot storage medium of same amount, thereby temperature boundary layer is diminished.Make like this and can within the longer time, operate the thermocline memory and by the heat transmission, equalized temperature completely not occur.This is feasible, especially because ground can the traditional much bigger pressure of cylinder of steel wall 5 of absorptance.
For fear of in being included in chamber 49 as the liquid of hot storage medium, from ground, 51 h substances and this material may form undesirable product with liquid reactions, with the tank with shown in Fig. 1, identical mode is lined with isolated component 19 to chamber 49.The structure of internal insulation element 19 basic identical with shown in Fig. 3 and 5 in this kind of situation.
The possibility of the another kind of structure of the internal insulation element 19 in the chamber in ground shown in Fig. 7 51.Or, in embodiment shown in Figure 7, internal insulation element 19 comprises the first separation layer 41 and the second separation layer 43.The second separation layer 43 preferably from the supporting and with the liquid 7 in being included in chamber 49, contact.For this reason, the second separation layer 43 is for example with the arranged in form of rectangular element layer.The first separation layer 41 is as extra isolated component and for example by material that can bearing pressure, made, thereby the second separation layer 43 is pressed towards the first separation layer 41 owing to being included in liquid effects in chamber 49 pressure on it, and these power that therefore apply are born by the first separation layer 41.
The first separation layer 41 for example can be formed by foam glass or insulating brick.
If it is preferred forming passage 57 in internal insulation element 19.Passage 57 is as relief outlet in this kind of situation, and liquid can flow to internal insulation element 19 back by this relief outlet.
Passage 57 is designed to avoid convection current in this kind of situation, thereby liquid flows through this passage 57, once and for example flows into and fill the space 59 that is positioned at internal insulation element 19 back.If the liquid be included in chamber 49 is sulphur, it is cooling and curing in space 59, thereby internal insulation element 19 is by the pressure support that comes from back.In order to ensure lasting pressure balance, if the temperature at passage 57 places always remains on height like this, sulphur can not solidify but continue in molten condition, is favourable.For this reason, for example can the set temperature sensor, utilize this sensor to measure temperature.If temperature reduces too much, for example can curing sulphur be melted again by the heating element heater with suitable.
This point correspondingly also is suitable for for example use of fused salt, and fused salt should keep liquid condition equally in the zone of passage 57, and if temperature reduces too much, thereby should be able to for example heat they are liquefied again equally.
In order to realize having the very large thermocline memory of accordingly large cross-sectional area, the composite memory with masonry inwall can be set.Sort memory presents by the example in Fig. 8.The use of composite memory makes and the span of tank deck can be remained in the limit feasible in Static Design.In order to produce composite memory, by internal insulation element 19, chamber 49 is divided into to the independent memory 61 of dispersion.Comprise identical liquid at each in independent memory, for example molten sulfur.The corresponding independent memory separate by internal insulation element 19 preferably connects on hydrostatics by through hole.This makes and the liquid level in the independent memory 61 disperseed can be consistent.
In Fig. 9, show a kind of flange with internal insulation element and connect.
For liquid being sent in tank or by it and removed, need to be to the tank connecting line.Connecting line is realized by suitable flange usually.Showing this flange by example in Fig. 9 connects.For this reason, form flange 63 on tank 3.Pipeline 65 is connected to the second flange 67.It is that part is concentric that the second flange 67 is designed to about pipeline 65 in this kind of situation, between flange 67 and pipeline 65, comprises isolated material 69.Simultaneously, there is internal insulation element 19 between the first flange 63 on tank 3 and the second flange 67.This design has also realized uniform isolation in the zone of flange.The connection of the first flange 62 and the second flange 67 realizes by traditional connection measure, for example, by screw 71.In addition, location sealing element between the first flange 63 and the second flange 67 usually.
Figure 10 illustrates the wing plate that is provided with the internal insulation element in pipeline.
The pipeline flow through for the corrosive liquids to especially hot provides corrosion protection, equally also can make pipeline have internal insulation element 19.In order to control percolation, for example can use accessory.This accessory is for example wing plate 73.In the zone of wing plate 73, internal insulation element 19 is interrupted, and block 75 is arranged in the zone of interruption.In order to seal pipeline 65, can be positioned to make it to hit wing plate 73 and lean against on block 75.By making wing plate 73 pivotables, can get through pipeline 65.The material that the use of internal insulation element 19 has prevented from flowing through the heat of pipeline 65 directly contacts with the material of pipeline 65.In order to protect block 75 and wing plate 73, they are provided preferably with high-temperature-resistant and anti-corrosion coating 77.
