Abstract
The elements are in the form of rigid hollow balls (1), the interior of which are wholly or partially filled with a latent heat storage material. Heat transmission from a hot to a cold region is effected by cyclic transport of the balls between the hot and cold regions by means of a Ljungström heat exchanger or in a column heat exchanger. The balls are cleaned by frictional contact with one another as a result of their movement in a fluidized bed in the exchanger, or by rotation of a static bed in a rotary heat exchanger. The heat storage material may be a metal or a chemical compound, e.g. LiH, LiF or MgF2. <IMAGE>
Description
SPECIFICATION
Heat-transmitting Elements for Regenerative
Heat Exchange
The invention relates to heat-transmitting elements for regenerative heat exchange.
The invention starts from known latent heat stores which are known as elements with a great thermal capacity.
These latent stores transmit the heat from the hot region to the cold region by means of an indirect medium, for example metallic or chemical compounds which melt in the hot region and solidify in the cold region.
The known latent storage materials are constructed in the form of stationary plates or of containers.
In many industrial cases, particularly in the case of heat exchangers between gases with a high dust or soot content or contaminated liquids, incrustations form on the heat exchanger surface of the known heat exchangers and can only be removed with great difficulty.
The object of the present invention consists in providing heat-transmitting elements which render possible an intensive heat exchange without problems and the cleaning of which is effected without great expenditure on apparatus.
According to the invention, this problem is solved in that the elements are constructed in the form of rigid hollow balls or as hollow polyhedrons of temperature and corrosionresistant material, the free interior being wholly or partially filled with a latent storage material.
Furthermore, the elements according to the invention can be used in a fluidized bed or a bed of loose material.
Heat transmission from a hot to a cold region is effected by cyclic transport of the elements between the hot and the cold regions.
In the hot chamber, the heat storage is effected in the elements by heating the wall and the latent store as a solid (internal), or by melting of the filling and heating of the liquid phase after the melting of the latent store.
After the transport of the elements into the cold chamber, the surrender of heat is effected by cooling of the wall and of the liquid phase (internal) to the solidifying temperature and further by surrender of the heat of solidification and heat from the cooling of the latent storage material as a solid phase.
The decisive advantage of the invention consists in the fact that the elements according to the invention are easy to clean, that is to say they necessarily clean themselves when used as a fluidized bed or bed of loose material.
The elements according to the invention work similarly to the latent storage material and at the same time have a high coefficient of heat transmission at the boundary gas-element surface in a fluidized bed and a great thermal capacity by filling with a latent storage material.
Embodiments of the invention are illustrated in the drawings and will be described in more detail below.
Figure 1 shows 2n element according to the invention formed as a hollow ball,
Figures 2, 3, 4, 5 show various arrangements of elements according to the invention in a Ljungström heat exchanger,
Figure 6 shows the use of the elements according to the invention as a fluidized bed in a column heat exchanger,
Figure 7 shows an arrangement of the elements as a static bed in a column heat exchanger.
The element according to the invention shown in Figure 1 consists of a hollow ball 1 which is composed of the wall 2 (with or without a capillary structure 5 at the inside of the wall 2), a latent storage material 3 and an inert gas 4 if the hollow ball 1 is only partially filled with the latent storage material.
The latent storage material may consist of a metal, for example sodium, aluminium or, for high temperatures, silver or chemical compounds such as for example LiH, LiF, MgF2 or the like.
The wall 2 may consist of metallic or nonmetallic materials.
Figures 2 to 4 show a rotor of a Ljungström heat exchanger 6 with a vertical shaft 7. In Figure 2, the elements 1 according to the invention are above a conventional storage material 8; in Figure 3 they are below. Figure 4 shows a Ljungström heat exchanger without conventional storage material, only with the elements 1 according to the invention. The cold gas inlet is designated by 9 and the hot gas inlet by 10. According to the direction in which the elements 1 are approached by the flow, a static bed or a fluidized bed develops. The fluidized bed is only formed if the flow of gas is introduced into the heat exchanger from below.If, for example, the shaft 7 of the rotor 6 is disposed horizontally (Figure 5), and the elements 1 are constructed in the form of a static bed, the cleaning of the elements is effected by the rotation in the sector compartment without additional energy requirements for a blow-off device. Figure 6 shows a column heat exchanger with a fluidized bed wherein the hot gas is introduced at 11, heats the elements 1 and leaves the column again at 12. The cold gas enters at 13 and leaves the column at 14. The heated elements sink down through a device 1 5 into the lower part of the column and are returned to the upper part of the column via a pneumatic or mechanical transport system 16, not illustrated in detail.
Figure 7 shows a heat-exchange column with a static bed wherein the heated elements 1 reach the lower part of the column in portions for example by means of a rotary-vane lock 17, heat the cold gas there and are returned to the upper part of the column via the transport system 16.
