Definitions
- the invention relates to a regenerative heat exchanger and a method for transferring heat from a first free-flowing solid to a second free-flowing solid.
- Heat exchangers or heat exchangers are known.
- the DE 30 27 187 A1 a recuperative heat exchanger for indirect heat transfer between free-flowing solids.
- This recuperative heat exchanger consists of a bundle of mutually parallel tubes, wherein adjacent tubes abut each other at least on one side surface.
- the tube bundle is arranged horizontally and rotatable about an axis of rotation.
- the tubes conveying ribs are fixed so that the free-flowing solid is conveyed by the rotation of the tubes about the axis of rotation parallel to the extension direction of the tubes through the respective tube.
- the first solid is conveyed in one direction, while at the same time the second solid is conveyed in the opposite direction through the other part of the tubes. In this case, the heat is at least partially transferred from the warmer solid through the tube wall to the colder solid.
- the heat exchanger according to the invention is designed as a regenerative heat exchanger.
- the first free-flowing solid and the second free-flowing solid are moved successively over the heat exchanger surface of the heat exchanger for heat transfer.
- the hot first free-flowing solid releases its heat to the heat exchanger surface during its movement along the heat exchanger surface.
- the second free-flowing solid absorbs the heat from the heat exchanger surface. In this way, the heat is at least partially transferred from the first free-flowing solid to the second free-flowing solid. Since both solids are brought into contact with the same heat exchanger surface, very high heat transfer efficiencies can be achieved.
- the heat exchanger according to the invention also has a positioning device by means of which the position of the heat exchanger surface between a heat absorption position and a heat release position can be changed. To heat the heat exchanger surface, this is brought by the positioning in its heat receiving position.
- the first free-flowing solid moves in a direction of movement from a first side to a second side of the heat exchanger surface.
- the two sides of the heat exchanger surface are arranged one above the other in the vertical direction.
- the heat exchanger surface heats up more in the region of its first side than in the region of its second side. This is due to, that the first solid cools continuously as it passes through the heat exchanger while delivering the heat to the heat exchanger surface.
- the supply of the first free-flowing solid is stopped in the heat exchanger and the positioning moves the heat exchanger surface in the heat release position.
- the heat exchanger surface changes its position such that the subsequently supplied second free-flowing solid first impinges on the less heated second side of the heat exchanger surface and is forwarded from there along the heat exchanger surface to its first side.
- the first side of the heat exchanger surface is arranged in the heat absorption position in the vertical direction seen over the second side, while the second side of the heat exchanger surface in the heat release position is vertically above the first side.
- the respective solid can trickle exclusively or at least assisted by gravity along the heat exchanger surface from top to bottom.
- the regenerative heat exchanger works as it were according to the "countercurrent principle". This ensures a high efficiency in the heat transfer from the first to the second free-flowing solid. Both solids are passed one after the other over the same, entire heat exchanger surface.
- the first hot, free-flowing solid is a calcium oxide (CaO) enriched solid.
- the second free-flowing solid is preferably a calcium carbonate (CaCO 3 ) enriched solid.
- the heat transfer can take place between the first solid stream led out of the calciner and the second solid stream leading into the calciner.
- the regenerative heat exchanger can therefore be an integral part of the calciner.
- the heat exchanger housing is provided in particular for embodiments of the heat exchanger surface, the non-fixed parts with each other, such as loose contiguous packing.
- Such fillers can be very easily filled into the heat exchanger housing.
- the heat exchanger housing does not have to be completely closed for this purpose. It can have a grid-like structure. Housing openings must be designed in their shape and / or size so that the filler can not fall through and can be held in the heat exchanger housing.
- perforated wall elements or grid elements may be used to form housing openings. In each case at least at a first and a second location, a housing opening is present, so that can be fed or removed via the two housing openings of each passing through the heat exchanger solid.
- the positioning can thereby the heat exchanger housing together with the heat exchanger surface between shift the heat release position and the heat absorption position.
- the first and the second housing openings in each case exchange their positions.
- This makes it possible to achieve a compact design of the regenerative heat exchanger, which requires little space.
- this can be designed as a rotating device which rotates the heat exchanger surface or the heat exchanger housing with the heat exchanger surface between the two positions.
- the axis of rotation preferably runs transversely to the direction of movement of the solids through the heat exchanger.
- the axis of rotation can be arranged approximately horizontally. Between the two positions of the heat exchanger surface, this can then be rotated, for example, by 180 degrees.
- At least part of the heat exchanger surface may be formed by arranged in the heat exchanger housing packing. These fillers serve to increase the size of the heat exchanger surface, so that the provided for the contact with the respective solid heat exchanger surface for a given volume is large. This ensures that a sufficient passage cross-section for the passage of the respective solid remains.
- the shape and size of the packing not only the heat exchanger surface can be increased, but also the residence time of the passed solid and thus the contact time between the solid and the heat exchanger surface varies and be set as desired.
- the packing may form a solid structure or matrix and be immovably connected relative to each other. In this case, can be dispensed with a heat exchanger housing.
- the packing spacers have, so that the distance between adjacent packing ensures a sufficiently large passage cross-section for the passage of the respective solid.
- a spacer means may be used by the filler projecting projections, such as pins, rods, discs, disc segments or the like.
- balls or polyhedra can be used. These may alternatively or in addition to spacer means comprise one or more through holes through which the solid in question can be passed.
- Wavy or multiply angled plates or sheets can also be used as the packing.
- rods running transversely to the direction of movement of the respective solid can also be used as filling bodies.
- the same solid inlet and / or outlet is used to introduce the first and second solids into the heat exchanger.
- the heat exchanger surface is arranged between Festscherinlass- and solids outlet. Between the heat exchanger surface or the heat exchanger housing and the solids inlet may also be provided a Feststoffverteil observed which serves to distribute the solid in a surface which extends transversely to the direction of movement of the solid along the heat exchanger surface. This ensures a uniform contact of the heat exchanger surface with the solid.
- the solids distribution device distributes the solid in a substantially horizontal area. As a solid distribution device, for example, serve a distribution tray. This distribution trough can be fluidized, so that forms a particularly homogeneous fluidized bed and the solid uniformly distributed, which can then trickle over a variety of overflow openings from the distribution tray out to the heat exchanger surface.

Instead of the corrugated plates 79 also multiply angled plates or sheets 80 may be used, as in FIG. 6 is shown schematically. Due to the corrugated or angled shape of the plates 79, 80, the direct trickling through of the solids F1, F2 is prevented. The plates 79, 80 form obstacles, so to speak, which redirect the solid in its direction of movement over and over again in order to extend the contact time between the solid F1, F2 and the heat exchanger surface 57.
