Definitions
- the invention relates to a device for receiving hot, corrosive liquids, comprising a space enclosed with a wall for receiving the liquid. Furthermore, the invention also relates to a use of the device.
- a device for receiving hot, corrosive liquids for example, a container which is used for receiving a heat storage medium in a solar power plant.
- heat is generated during the daytime, as long as the sun is shining, with the help of solar energy.
- the heat is used to generate electricity.
- the heat is used to evaporate water and to drive a generator to generate electricity with the generated water vapor.
- solar energy is used to heat up a heat storage medium. This is stored in a well insulated container.
- the heated heat storage medium is removed and used, for example, to evaporate water.
- the heat storage medium gives off heat and is cooled.
- the cold heat storage medium is then passed, for example, into a second cold storage storage tank.
- large solar power plants require very large heat storage.
- it is necessary to heat the heat storage medium to correspondingly high temperatures.
- a heat accumulator is currently being operated in a solar power plant with a working temperature in the range between 290 and 390 ° C.
- an attempt is currently being made to extend the temperature range to 550 ° C or even to temperatures above it.
- heat storage media for example, salt melts are used. Due to the large amount of heat storage medium needed to operate a large solar power plant, alternatives are also sought here.
- Alternative heat Storage media are, for example, also those containing sulfur. Both molten salts and sulfur-containing thermal storage media cause corrosion at high temperatures to the usually made of steel containers. For example, some nitrate melts at temperatures of more than 550 ° C can lead to embrittlement of various stainless steels. Although the stainless steels remain stable, they are sensitive to shocks.
- Materials that resist the corrosive substances even at high temperatures are, for example, ceramics and glasses. In general, however, these can not be connected to large structures, as is necessary for the containers for heat storage, seal-free. Applied sealing material can be corrosively attacked at high temperatures. In addition, these materials are generally brittle and, when connected to a building, can not carry high internal pressures.
- Object of the present invention is therefore to provide a device for receiving hot, corrosive liquids, which is corrosion resistant and dense and has sufficient mechanical stability to accommodate large amounts of liquid can.
- a device for receiving hot, corrosive liquids which comprises a wall enclosed space for receiving the liquid, wherein the space has an internal insulation.
- the internal insulation can either rest directly against the wall of the container or it can be formed a gap between the inner insulation and the wall.
- the internal insulation prevents the hot liquid contained in the space from coming into contact with the wall. Due to the insulating effect of the internal insulation, the temperature of the side facing the wall is significantly lower than the temperature of the hot liquid. This will achieve that the temperature of the wall bounding the space can be kept below the temperature at which corrosion occurs.
- the internal insulation In order to protect the internal insulation, especially in the case of a gap between the internal insulation and the wall of the space in which the liquid is contained, from inadmissible forces acting thereon, the internal insulation preferably has passages through which the liquid can flow. This adjusts a pressure balance on the inside of the insulation and the outside of the insulation. The internal insulation thus does not need to be stable against an internal pressure. In particular, when the gap between the inner insulation and the wall is not uniform, or even the inner insulation partially rests against the wall and partially creates a gap, liquid flows through the passages in the gap until a pressure equalization occurs. A deformation of the inner insulation, which could possibly lead to destruction, is thereby avoided.
- the design of the passages is such that liquid can flow into the passages, but does not use convection. This allows liquid to flow out of the container through the passages, but no mass transfer occurs in the passages once they are filled.
- the liquid contained in the passages then also acts in an insulating manner. Although the liquid comes into contact with the wall of the room due to the passage through the passages, it has a lower temperature than the liquid in the reservoir, the thickness of the insulation being chosen such that the temperature in the region of the wall is so low that that no or at least minimal corrosion occurs.
- the inner insulation has expansion joints.
- the expansion joints are preferably also sized so that no convection begins therein.
- the passages in the inner insulation for pressure equalization simultaneously serve as expansion joints, which are used to prevent destruction of the inner insulation by thermal expansion. In this way it is possible to control even loads due to temperature changes without destroying the internal insulation.
- the extent of the passages and / or the expansion joints is dependent on the viscosity of the liquid contained in the space.
- the internal insulation can be constructed, for example, from essentially cuboidal elements.
- Substantially parallelepiped elements also include elements in which the width increases outwardly to conform to a container having a circular cross-section so that the expansion joints between the elements have a uniform width, as well as elements in the form of circular segments attached to are adapted to the diameter of the container are designed.
- the passages or expansion joints are, for example, gaps between the cuboidal elements.
- a further prevention of convection is possible in that the cuboidal elements are stacked offset to build the internal insulation. A gap between two cuboidal elements is then only as high as such a cuboidal element and is interrupted by a parallelepiped element of the next row.
- the internal insulation can be both self-supporting as well as formed by attachment of insulating elements on the wall.
- insulating elements are stacked to form an inner wall, whereby it can stand freely or rest against the wall of the room. It is particularly preferred if the self-supporting internal insulation has expansion joints.
- the second insulating layer may be formed of the same material as the internal insulation. It is also possible to use two different materials.
- the inner insulation which is preferably self-supporting
- the inner insulation which is preferably self-supporting
- the second insulating layer to be highly insulating Material, such as glass foam, contains.
- the internal insulation can also be made up of more than two layers. In this case, at least one layer is preferably a self-supporting internal insulation, the remaining layers may or may not be self-supporting. It is also possible, for example, to build up alternately self-supporting insulating layers and highly insulating material in several layers. Furthermore, however, it is also possible that all layers of the insulation are self-supporting.
- the second insulating layer when the second insulating layer is not self-supporting, it is advantageous if this is limited both on the inside and on the outside by a self-supporting internal insulation. However, it is preferred if each layer of the insulation is self-supporting.
- a seal made of a corrosion-resistant material is received between the inner insulation and the wall.
- the seal made of corrosion-resistant material may be, for example, an inliner, for example in the form of a corrugated sheet.
- a seal made of a corrosion-resistant material it is possible to use a non-corrosion-resistant metal for the wall.
- Corrosion-resistant materials for example corrosion-resistant stainless steels, are generally expensive and also have lower strength values than steels which are not resistant to corrosion in relation to the liquid contained in the space.
- the seal made of the corrosion-resistant material it is possible to make the wall of the enclosed space, for example a container, of a steel which is not stable to the liquid contained in the space. The seal made of the corrosion-resistant material prevents the liquid contained in the space from coming into contact with the wall.
- the device for storing the hot, corrosive liquid is, for example, a container.
- This generally has a wall and a lid, so that a closed space is formed, in which the hot, corrosive liquid is contained.
- the wall of the container may, for example, from the typical materials for container construction z. B steel or stainless steel to be built.
- a seal made of a corrosion-resistant material it is possible to use materials for the wall of the container, which are not resistant to corrosion compared to the liquid contained in the container.
- Suitable corrosion-resistant materials from which the seal can be made are, for example, graphite or aluminum. If the device for storing hot, corrosive liquids is a container, it is usually closed with a container lid. On the container lid insulating elements are then also attached. Due to the insulation of the container lid, it is also avoided in the area of the container lid that - especially when the container is completely filled - the container lid comes into contact with the hot, corrosive liquid. In addition, it is avoided that heat is released through the container lid to the environment.
- the storage space enclosed by a wall can also be a cavity in the ground.
- the cavity can be a natural cavity; alternatively, it is also possible to artificially create a cavity, for example.
- the advantage of a cavity in the ground is that greater heights of the memory can be realized, since they can be loaded by a higher hydrostatic pressure than conventional containers, since the forces occurring due to the hydrostatic pressure are absorbed on the wall of the soil.
- a large height for the room is particularly useful if the contained in the room, corrosive liquid is a heat storage, which is to be operated as a stratified storage. In a heat storage system operated as a stratified storage tank, there is cold liquid at the bottom and hot liquid at the top.
- a cavity in the ground is that a heat storage for a solar power plant can be operated well above 440 ° C even under pressure and at maximum temperature, as even with large storage systems, a system pressure of more than 1 bar can be applied.
- the hot, corrosive liquid can be stored in a cavity in the ground in the absence of air, which can greatly reduce the risk of fire.
- the in-situ insulation of the cavity in the soil prevents the hot, corrosive liquid from coming into contact with the soil and releasing substances from the soil or reacting with them and carrying away the solutes or the reaction products.
- the substances or reaction products dissolved from the soil can, for example, be added to other components of a plant in which the Device for storing hot, corrosive liquids is used, causing damage caused by increased corrosion or deposits.
- a cavity in the ground for example, can be artificially generated completely above ground, for example, by artificially heaping up a mound in which such a cavity is formed.
- a cavity in the ground can be partially underground, whereby both naturally occurring cavities and artificial cavities can be used. It is also possible that the cavity is completely subterranean. In this case, natural cavities are used in particular.
- an internal insulation is introduced into the cavity in the ground. This serves in particular to avoid, as already described above, that liquid which is stored in the cavity dissolves substances from the soil or reacts with substances from the soil.
- the material of the internal insulation both when used in a container as well as when used in a cavity in the ground, are suitable, for example, alumina, silicon carbide, silica, aluminum foam, glass foam or mixtures thereof. It is also possible to provide several layers, wherein the layers can be made of different materials.
- the device for storing the hot, corrosive liquid is a container, in particular a container with a metal wall, for example a steel wall
- the container wall despite the internal insulation has a temperature that lead to injury, for example, when touched can.
- the container wall is additionally surrounded by an outer insulation.
- mineral fiber mats or standard glass foam panels are suitable.
- a sheet metal such as zinc sheet, it can be avoided that moisture penetrates into the insulation.
- the inventive device for receiving hot, corrosive liquids is particularly suitable for receiving a heat storage medium in a solar power plant, such as a parabolic trough solar power plant.
- Heat storage media that may be employed include, for example, molten salts or sulfur-containing thermal storage media.
- Sulfur-containing heat storage medium is in particular elemental sulfur.
- Particularly suitable as anion-containing additives are those which do not oxidize the sulfur at the operating temperature to corresponding oxidation products, for example sulfur oxides, sulfur halides or sulfur oxide halides. It is furthermore advantageous if the anions-containing additives dissolve well in the sulfur.

- FIG. 9 shows a flange connection with internal insulation
- Figure 10 is a flap with internal insulation.
- FIG. 1 shows a device designed as a layer store for receiving a hot, corrosive liquid.
- a stratified storage 1, as shown in FIG. 1, can be used, for example, as a heat store in a solar power plant.
- the stratified storage 1 comprises a container 3, which is constructed, for example, from a metallic material, for example steel.
- a container wall 5 is made of the metallic material, wherein the wall thickness of the container wall 5 is selected so that it is mechanically stable against the pressures occurring in the container.
- the downward increasing hydrostatic pressure of a liquid contained in the container 7 should be considered.
- a further lid 1 1 may be provided, which rests on completely filled container 3 on the liquid contained in the container 3 7, so that no gas is contained in the container 3.
- 1 1 compensation areas 13 can be provided on the further dekel. These can be designed, for example, in the form of a bellows.
- the further cover 1 1 can be positively connected to the container wall 5, for example by a welding process.
- a gas-tight connection is possible.
- With an increase in the liquid level or a decrease in the liquid level then raises or lowers the other lid 11 so that it always closes the container so that no gas is contained in the container.
- a first manifold 15 When using the container 3 as a stratified storage 1 is located in the upper region of the container 3, a first manifold 15. About the first manifold 15 evenly hot liquid can be added to the container. At the same time, in order to keep the liquid level in the container constant, via a second manifold 17 on Bottom of the container removed 3 colder liquid. Cold liquid is uniformly withdrawn through the first distributor 15 and the second distributor 17, so that preferably no convection flow and therefore very little vertical heat conduction in the container are established. In this way it is possible to store liquid in the container in such a way that the lower part contains the generally colder liquid with a higher density and in the upper part the warmer liquid with a lower density.
- the liquid in the container has two temperatures, namely a higher temperature in the upper region and a lower temperature in the lower region. Between the hot and the cold area, a temperature boundary layer is formed. Since the heat conduction in the liquid can not be prevented, in the real case, however, no sharp separation between hot and cold liquid is possible, but it forms a temperature transition from the hot to the colder liquid. Due to thermal conduction, the transition becomes increasingly blurred as the duration of storage increases.
- a molten salt or a sulfur-containing heat storage medium is used as the liquid 7 serving as a heat storage medium.
- sulfur-containing heat storage medium is particularly elementary Sulfur, which may, however, be contaminated or may contain other additives.
- Both molten salts and sulfur are highly corrosive at higher temperatures than ferrous or nickel containing materials. For example, nitrate melts at temperatures of more than 550 ° C lead to the embrittlement of stainless steels. The stainless steels remain stable, but are shock sensitive.
- Sulfur-containing heat storage media for example, sulfur with 1% potassium sulfide, produce in typical iron / nickel stainless steels at temperatures above 350 ° C, a noticeable corrosion, which leads to increasing temperature of 500 ° C in a short time for sweeping destruction of stainless steels.
- chloride-containing molten salts are highly corrosive at high temperatures.

- the temperature at the wall 21 is significantly lower than the temperature of the liquid 7 in the container 3.
- An exemplary construction of the internal insulation 19 is shown in FIG.
- the internal insulation, as shown in Figure 2 is self-supporting.
- essentially cuboidal, optionally to match the rounding of the container also slightly trapezoidal elements 23 or elements 23 in the form of circular segments are arranged offset in two rows.
- the column 25 serve to compensate for different temperature expansions of the materials of internal insulation 19 and container wall 5.
- the cuboidal elements 23 stacked one above the other in rows, wherein it is preferable to each stacked cuboidal elements 23 also arranged offset from one another.
- the staggered arrangement, the column 25 are limited in their geometric extension.
- the gaps 25 are dimensioned so that no convective flow is formed.
- liquid 7 can flow into the column 25, however, a constant mass transfer in the gaps after they have been once filled with the liquid 7 should be avoided.
- the liquid contained in the gaps 25 then also insulates.
- the design in two staggered rows it is avoided that liquid passes through the inner insulation 19 to the wall 21.
- the internal insulation it is also possible for the internal insulation to be constructed from a row of cuboidal elements 23. In this case, the liquid passes through the gap 25 to the wall 21. Due to the insulating effect of the insulation 19 and the design of the column 25 such that no convective flow occurs, the temperature of the column 25 is also reduced flowed liquid, so that the temperature of the liquid 21 coming into contact with the wall is lower than the temperature of the liquid 7 in the container 3.

- the wall thickness of the wall 21 which forms the container wall 5 is selected so that the wall 21 is stable against forces acting on it, for example due to the hydrodynamic pressure of the liquid contained in the container.
- the insulation boards 27 are fastened to the wall 21, for example, with suitable wall hooks 29.
- wall hooks 29 The advantage of using wall hooks 29 is that the individual insulation panels 27 of the internal insulation 19 can be mounted in a simple manner and, if necessary, also dismantled again.
- this has the disadvantage that a simple disassembly is no longer possible.
- a gap 25 is formed.
- the dimensions of the column 25 are to be selected in the embodiment shown in Figure 3 so that no convective flow in the gap 25 is formed.
- the gap 25 is filled by incoming liquid during filling, but this then remains in the gap 25 and thus also serves for insulation.
- the insulating panels 26 are generally not flush against the wall 21, liquid also flows behind the insulating wall. plates 27. Due to the insulation with the insulation boards 27, the liquid that comes into contact with the wall 21, but already cooled so far that it no longer acts on the wall 21 corrosive.
- a corrosion-resistant coating 31 In order to protect the insulation boards 27 against corrosion, it is possible to provide these additionally with a corrosion-resistant coating 31.
- any coating known to the person skilled in the art is suitable as the corrosion-resistant coating. Suitable coatings are, for example, coatings with enamel or Al 2 O 3 coating.

- a possible construction of a container lid with insulating elements is shown in FIG.
- FIG 4 for a container lid substantially corresponds to the structure of a container wall shown in Figure 3 with insulating panels mounted thereon.
- 33 insulating elements 35 are mounted on the container lid.

- the corrosion resistant Seal 39 is, for example, a stainless steel inliner. This can be designed, for example, in the form of a corrugated sheet.
- the corrosion-resistant seal 39 is followed on the inside by a first insulating layer 41.
- the first insulating layer 41 is preferably self-supporting and composed of quasi-shaped elements which are stacked on top of one another. Between the individual cuboid elements of the first insulating layer 41, it is advantageous if gaps are formed, as is also illustrated, for example, in FIG.
- the first insulating layer 41 is made of, for example, a high heat insulating material. As a result, a good insulation is achieved.
- the first insulating layer 41 is followed by a second insulating layer 43.
- the second insulating layer 43 is made, for example, of an abrasion-resistant material, so that this particular also serves to ensure that the internal insulation 19 is not damaged by movement of the liquid in the container.
- the second insulating layer 43 is preferably self-supporting and layered, for example, cuboidal elements. Again, it is advantageous if 43 gaps are formed between the individual elements of the second insulating layer in order to compensate for different thermal expansions of the materials of the first insulating layer 41, the second insulating layer 43 and the container wall 5 can. Through the gap 25 between the individual elements of the first insulating layer 41 and the second insulating layer 43, liquid can flow in the direction of the wall 21. The liquid then collects on the corrosion-resistant seal 39. The fact that there is liquid on both sides of the insulation 19, which in each case has the same pressure due to pressure equalization, it is avoided that acts on the insulation 19, a high internal pressure, not from the Outside is compensated. A deformation of the inner insulation 19 is thereby largely avoided.
- the outer insulation 45 may be formed of, for example, conventional insulating materials such as mineral fibers or glass fibers. To make the container weatherproof, the outer insulation 45 then becomes For example, covered with sheets 47.
- the sheets 47 that are used, for example, commercially available zinc sheets, which are particularly weather resistant.
- FIG. 6 schematically shows a device for receiving hot, corrosive liquids in the form of a cavity in the ground.
- the device for receiving the hot, corrosive liquid as a cavity 49 in the soil 51.
- This has the advantage that no container limitation in the form of a container wall 5, which is stable to high pressures, is necessary.
- the forces acting on the wall 21 forces are absorbed by the soil 51.
- the device may also be a layered memory. If the device for receiving the liquid is a stratified storage, then a first feed 53 is provided in the upper region, through which hot heat storage medium can be fed into the cavity 49 or can be removed from the cavity 49 and a second feed 55, the opens into the lower region of the cavity 49 and can be removed or supplied via the cold heat storage medium.

- the first insulating layer 41 may be formed of glass foam or insulating stones, for example.
- passages 57 are formed in the inner insulation 19.
- the passages 57 serve as relief leaks through which the liquid can flow behind the internal insulation 19.
- the passages 57 are thereby designed so that a convective flow is avoided, so that once fluid flows through the passages 57 and, for example, in cavities 59, which are located behind the inner insulation 19, flows and fills them. If the liquid contained in the cavity 49 is sulfur, it cools in the cavities 59 and solidifies, whereby the inner insulation 19 is supported by back pressure. In order to ensure a continuous pressure equalization, it is advantageous if the temperature at the passages 57 always remains so high that the sulfur does not solidify but continues to exist as a melt. For this purpose, it is possible, for example, to provide temperature sensors with which the temperature is measured. If the temperature decreases too much, it is then possible, for example, to melt the solidified sulfur again by using suitable heating elements.
