Fig. 19 is an illustrative view of a heating control arrangement embodying the curved conducting surfaces.
Fig. 20 is a perspective view of a sleeve having a heat control and a heat conducting packing.
Fig. 21 is a perspective view or" an arrangement with an internal sleeve eccentrically arranged within an outer sleeve and with a heat control rod extended through the outer sleeve.
Fig. 22 is a diagrammatic view of an external heat control sleeve extended outside or around a tower section.
Fig. 23 is a perspective View of a towe section using concentric sleeves with the inner sleeve having radially extending walls.
Referring now to Figure 1, 3i represents a sleeve formed of capillary material with an open to 32 and a closed bottom 33, Fig. 5, having a central hole 34 therein through which vapor may easily pass. The sleeve material is cut so that the strands of the material extend across one another and at forty-five degrees and one hundred and thirty-five degrees. In Fig. 2, the capillary or mesh material sleeve 35 is shown wherein the 3 mesh strands run at zero and ninety degrees. The sleeve 35 has the bottom 33 shown in Fig. 5. It will accordingly be apparent that the evaporative tower can be arranged with the strands extending at difierent angles with the horizontal.
In Figure 3, a sleeve 36 of mesh or capillary material has radially extending partitions 3? crossing one another at the center of the sleeve 36 as shown clearly in Fig. 6, thereby providing for additional screen surface for various diffusional process systems. The larger the screen surface the more efiective the evaporating operation.
In Figure 4, there is shown a tower formed of mesh having the bottom 33 with a hole 3-4 therein and with holes for the outward flow of gas at 38 and 39. In Figure 7, there is shown a tower arrangement comprising vertical sections 4!, i2, 43 and 4 stacked one about the other. The number of sections in any tower is not to be limited but depends upon the use to which the tower is to be put. These sections may also be of a series and can be of any single piece or of multiple pieces and assembled together in sections. Opening 45 controls the liquid level of the screen sections. Between the two upper sections is a liquid drain 55. The liquid drain 46 may or may not be of capillary or screen material. It is however preferably made of screened material.
In Figure 8, there is shown an arrangement of disc type ii of capillary material having respectively vapor openings E8. The discs are arranged so that the openings 48 are alternately one hundred and eighty degrees apart, whereby to cause a circuitous path of the vapor fiow in passing from one space to another space. In Figure 8A, discs 49 similar to the discs fl'l are assembled upon a central shaft or rod 5I which may serve to provide the necessary heat to the evaporating tower to render more efiective the evaporating action.
In Figure 10, a plurality of screen or mesh sleeves 52 may be assembled within container '53 in cluster relationship or may be assembled in rows within a connection 54. In Figure 9, there is shown a section formed of a plurality of concentric sleeves 55, 56, 57 and 58. These sleeves are arranged on a drain 6i and the drain has a plurality of vapor risers 62 communicating with spaces between the sleeves and another inner sleeve. In Figure 11, there is shown a plurality of sections and arrows indicating the vapor flow to the sections, in which there is illustrated the direction of flow of vapor through the stacked arrangement with the vapor walls in the section arranged in a somewhat different manner. There is provided a plurality of sections 64, 85, 66, 5! and 68. The holes can be so formed in the bottoms and in the sides of the multiple sleeves as to provide parallel flows in parallel spaces or series flow through parallel spaces in serpentine fashion. For instance, in section 64 the flow as indicated by the arrow 69 is parallel through different spaces of the section. In section 65, the vapor enters at II and passes upwardly and downwardly through the parallel spaces and finally outwardly through I2. Holes 13 and I I are provided between adjacent spaces. In section 66 the vapo enters one side as at 14 and then passes upwardly and laterally through top holes 15 in the several partitions. The vapor will fiow outwardly through openings I6. In section 61 there is provided for a double or multiple serpentine flow of vapor through the several parallel spaces. Part of the vapor will take a path 11 while the other 4 will assume path 18. A similar parallel flow arrangement is provided through section 68 except that the respective flows enter the inner portions of the bottom of section 68 at 1'9 and leave the outer spaces.
In Figure 12, there is shown a collection of screened discs BI arranged in a drain tube 82 which is slightly inclined. The upper paths of the discs have vapor holes 83 through which vapor passes to one space after the other.
In Figure 13, there is shown a sleeve having open ends 85; '86 is a tower wall through which is extended a heating rod 8'] with terminals 88 extending from the opposite ends of the same. The sleeve is of mesh material.
In Figure 14, there is shown concentric internal and external sleeves 9i and 92 respectively having lead wires 93 and 94 extending therefrom. These wires will conduct current to the respective sleeves to heat the same for the purpose of promoting the evaporating action within the sleeves.
In Figure 15, there is shown a sleeve 95 with a central heating rod 96, the construction being similar to that shown in Figure 13 except that the sleeve is extended vertically to permit the upward fiow of vapor.
In Figure 16, the heating rod 96 is provided withlaterally extending discs 91 connected to the rod in vertically spaced relationship so that heat will be conducted outwardly from the rod. This heating arrangement is within a column wall 98.
In Figure 18, there is shown a plurality of capillary sections IIlI, I62, I83 and I64. These sections are tied together electrically and have terminals I05 and Hit extending from the same. When current is extended through the section. the same will be heated to give better evaporating action. In Figure 18A, there is shown the same tower as in Figure 18, but with different particles in each of the sections whereby to further improve the evaporating action. In the bottom section, there is a packing of glass beads Sill. In the section thereabove is a wire packing I88. In section IE3 is a collection of rings I59 and in the top section is a collection of beryl pieces IIII.
In Figure 19, there is shown an illustrative sectional view of a sleeve II2 having a central heating element H3 with terminals II and I I 5 extending from the same. Connected to this terminal H3 are a plurality of vertically spaced heat conducting elements or drains which are dished and are indicated at IIE. Each of these have openings II'I through which vapor may pass upon moving upwardly through the tower.
In Figure 20, there is shown a sleeve I I8 having terminals II9 and I2!) extending from the same and packed with a heat-conducting packing I2I.
In Figure 21, there is shown an outer sleeve I23 and an inner sleeve I24 eccentrically dis posed within the sleeve I23. These sleeves are of mesh or capillary material and the inner sleeve I26 is offset so as to provide space for a heating rod I25 having terminals I26 and I2? extending therefrom.
Figure 22 shows a jacket type of heater as indicated at I29 formed of mesh material and adapted to surround the tower sections. Terminals I3! and I32 extend from the jacket I29.
In Figure 23, there is shown concentric sleeves IPA and I35. The sleeve I35 is within the sleeve I3 i. The section has a bottom I36 with an opening I31 therein for receiving the vapors. Within the inner sleeve I35 are a plurality of radially extending partitions I38 to give added area. 7
It should now be apparent that the various sections forming a part of the tower can be made in many different ways and the apparatus formed by these sections can be effective in any number of processes dealing with vapors or liquids where it is desired to have the liquids deposited on large areas either for the purpose of being evaporated or for the purpose of collecting the same from vapors and condensations.
While various changes may be made in the detail construction, it shall be understood that such changes shall be within the spirit and scope of the present invention as defined by the appended claim.
Having thus set forth and disclosed the nature of my invention, what is claimed is:
A distillation apparatus comprising a plurality of concentrically disposed cylindrical bodies of mesh material, a common drain bottom of mesh REFERENCES CITED The following references are of record in the file of this patent:
