Definitions

  • this invention relates to a regenerative moisture exchanger for gaseous media, primarily two air streams of diiferent temperatures and moisture contents.
  • the moisture exchanger has an exchanger body or packing provided with means having hygroscopic properties, which alternately are passed by an air stream to be dried or dehumidiiied and an air or gas stream for regeneration or reactivation of the exchanger body or packing after that the same has separated a predetermined quantity of moisture from the first-mentioned stream. It is known to provide a moisture exchanger of this kind with at least three inlets and outlets for the two media and with sections of the exchanger body or packing corresponding thereto, which sections are stationary, valve members for alternate guiding of the media through the sections being provided in the inlets ⁇ and outlets respectively.
  • One main object of the invention is to provide a moisture exchanger of this kind, and one which is particularly suited for very large air quantities per unit time for which thus the otherwise usual construction with a rotatable exchanger packing would result in enormous dimensions, whereas on the other hand a subdivision into a plurality of minor rotatable units should cause com* plications.
  • FIG. 1 is a perspective View of a moisture exchanger constructed according to the invention and with parts removed and other parts broken away for clarity.
  • FIG. 2 is another perspective view of the same moisture exchanger with an enclosing casing removed.
  • FIG. 3 is a cross-section of the moisture exchanger following the line III-III of FIG. l in a reduced scale.
  • FIG. 4 shows the portion encircled by the circular line A in FIG. 2 of an exchanger packing, represented in a larger scale.
  • FIG. 5 is a perspective view of another embodiment of the invention with parts broken away.
  • FIGS. 6 and 7 are two cross-sectional views of this moisture exchanger of FIG. 5.
  • the moisture exchanger has exchanger bodies or packings lll, 12, 14, 16, which are disposed in parallel and mutually spaced relationship.
  • the number of exchanger packings may vary depending on the desired capacity of the moisture exchanger.
  • the exchanger has four packings.
  • Each exchanger packing may be in the form of a body of square shape having thin layers arranged within a frame or the like, which layers according to FIG. 4 may be alternately plane and corrugated.
  • the plane layers 18 and the corrugated layers 20 bear against one another and are suitably connected with one another along the ridges of the corrugations.
  • the layers or sheets 1S, 2li are preferably of brous, ⁇ and if desired, inorganic material such as asbestos to obtain best efficiency.
  • the sheets or layers 18, 20 form channels extending from end to end between the broad sides of the packings.
  • the dimensions of the exchanger packings or bodies in the longitudinal extension of the channels may amount to 200 to 300 millimeters.
  • the exchanger packings 10 to 16 stand on two elongated boxes 22, 24 and two elongated boxes 26, 28 are disposed over the tops of said packings.
  • the left-hand lower box 22 according to FIGS. 1 to 3 is connected through a fan 34 and a conduit 30 with an inlet for the air stream to be dried.
  • This conduit may also be connected to an inlet for fresh air or to ⁇ a space or room, the air of which is to be dried to a predetermined moisture content.
  • the dried or conditioned air passes through the box 28 and a tubular exhaust piece 32 to that space or room in which the moisture content of the air is to be controlled.
  • air is supplied through ⁇ an intake 36 in which air has been preheated by a heater 38 or similar device so that the air attains a low relative moisture content and becomes capable in a corresponding degree to regenerate or reactivate the exchanger packings.
  • the regenerating air escapes through the right-hand lower box 24 to a conduit 40 connected to a fan 42.
  • the consumed regenerating air may be exhausted into the surrounding atmosphere.
  • a higher pressure is maintained than in regenerating air circuit, so that possible leakage of air occurs in the direction towards said circuit, for which reason the air contained therein is prevented from intermixing with the fresh air.
  • the exchanger packings 10 to 16 are separated from one another by inclined walls 42, 43, 44, 45, 46.
  • the partition walls 43 to 45 thus subdivide each interspace between the exchanger packings into two compartments, which extend over the total facial areas of the packings and have a breadth variable in a vertical direction.
  • walls 47 made of sheet material are provided (FIG. 3).
  • the left-hand box 22 is at its top side formed with recesses 0r openings 48 in its top, having at least one recess or opening for each exchanger packing, which recesses house valve members, such as pivoted aps Sti.
  • the upper righthand box 28 has in base side recesses or openings 52 adjacent each exchanger packing.
  • valve members such as pivoted flaps 54.
  • the upper left-hand box 26 on the regeneration side has recesses or openings 56 provided with valve members such as iiaps 58 and the saine structure is present in the right-hand box 24, the recesses or openings of which are indicated at 60 and the flaps thereof 62.
  • the flaps are not shown in FIGS. 2 and 3.
  • the flaps Sil located at the base to the left of each of the three exchanger packings 10, 12, 14, are shown in open position, which is also the case with the flaps 54 in the upper right-hand box 28.
  • the result is that air sucked into the channel 30 by the fan 34 is urged upwards through the recesses 48 of the box 22 and thereupon enters the compartments thereabove, which on the left-hand side of FIGS. 1 and 2 are confined by the intermediate walls 43, 44 and 45, respectively.
  • the air passes now through the exchanger packings 1t), 12, 14 over the entire front area thereof in three partial streams, which thereupon are collected in the right-hand upper box 28 and escape into the space or room to be conditioned.
  • the partial streams are indicated by lines 64, 65, 66.
  • the fourth exchanger packing 16 is, however, sealed against the boxes 22 and 2S due to the fact that the flaps 5G and 54 adjacent said exchanger packing are closed. Instead the flap 58 in the upper left-hand box 26 adjacent the exchanger packing 16, is in open position and so is also the remotest tlap 62 in the right-hand lower box 24.
  • the reactivated exchanger packing 16 is connected to the drying air system by the Opening of the cooperating iiaps 5t?, 54 and the closing of the apertaining aps 58, 52. Instead, that exchanger packing which during the longest time has been active in the drying operation is shut off from the drying air system by re-adjustment of its flaps instead of being passed in countercurrent by the hot regenerating stream. In this way a repeated resetting of the aps is brought about at suitable time intervals so that permanently the greater number of exchanger packings is operative in the drying of the utilizable air, whereas one packing r a minor number of packings are subjected to reactivation.
  • a surrounding casing 68 encloses three packing sections 12, 14, 16, which on both sides are separated from one another by partition walls 44 and 46 projecting in this case perpendicularly to the sections.
  • the sections are placed side by side and may together form an elongated body 7G extending through the whole moisture exchanger.
  • openings or holes 48, 60, S6 and 52 respectively, laterally of each section.
  • the streams of air or gas are guided through the sections by means of plate-like slides 73, 74, which are slidably titted in slots formed by the boxes and the walls 71, 72 at the upper and lower portions of the moisture exchanger.
  • Each disc slide has apertures on both sides laterally of the exchanger body 70.
  • the disc slide 73 is provided on one side with a central aperture or opening 76 and on the other side with two lateral apertures or openings 78.
  • the apertures 7S are disposed in spaced relation to one another externally of the aperture 76 and their length is double of that of last-mentioned aperture. Therefore, the disc slides obtain a length which, with two graduation steps, exceeds the total length of the three sections of the exchanger body 7).
  • the valve slides 73 and 74 are at their ends enclosed by stationary casings 8), 82 and 84, S6, respectively, each of said casings having a length equal to two sections.
  • the casing form slots which counteract lateral leaking out of air from the interior of the apparatus.
  • valve slide 7S has its opening 76 registering with the openings 53, 54 and thus the channel 28 is in communication with the compartment in front of the section 16, whereas the two remaining secions 12 and 14 are shut ott from said channel.
  • the one lateral opening 78 of the disc slide 73 is positioned straight in front of the sections 12 and 14 for which reason these sections are in communication with the box 26.
  • the disc slide 74 is formed in the same manner but its openings are mirror-reversed relatively to the openings or apertures of the disc slide 73.
  • the central short opening 88 of the disc slide 74 registers with thc openings 48, 49 of the channel 22 and in this way connects this channel with the compartment in front of the section 18.
  • the one elongated opening 90 of the disc slide 74 registers with the openings 60, 61, which are positioned between the compartments straightly in front of the sections 12, 14 and the channel 24.
  • the two elongated openings 78 of the disc slide 73 will register with its pertaining section 12 and 16, respectively. The same is the case with the elongated openings 96 of the disc slide 74. These sections will thus be operative for drying or conditioning of air which enters through the channel 26 and escanes through the channel 24.
  • valve slides 73, 74 By displacement of the valve slides 73, 74 by still one graduation step to the right according to FIG. 5, their central openings 76 and 88, respectively, will be located straightly in front of the section 12, which is regenerated thereby.
  • the left-hand elongated openings 78, open connection between the channels 26, 24 and the sections 14, 16 which thereby become operative for the drying of fresh air.
  • the right-hand elongated openings 78, 90 are located within the casings 82 and S6, respectively and are thus out of operation.
  • the Valves may be reset by means of servomotors which are driven by a pressure fluid or by electricity.
  • the resetting may be caused to take place automatically at regular time intervals or in response to hygrostates scanning the moisture content in one of or both air and gas streams.
  • the displacements of the disc slides shall take place intermittently.
  • the displacements of the slides may be made continuous since minor strips of the sections are set free and sealed off each time by the slide openings.
  • FIGS. l to 4 may be modified so that the partition walls 43, 44, 45 are modified to form valve aps turnable about horizontal axes located approximately at the middle portion of said walls. These flaps are then caused to assume either the position shown in FIGS. l and 2 or a crossing position where they instead extend obliquely upwards to the left. In this way the valve system may be simplified substantially.
  • the iaps may further be combined with plates articulated at their upper and lower edges and adapted to lay open or cover the openings in the boxes 22, 24, 26, 28 in the sequence described above.
  • a regenerative moisture exchanger for gaseous mee dia comprising at least three sections of hygroscopic exchanger body inlets and outlets for the media, the sections being mounted stationarily and in spaced relationship to each other, valves arranged in the inlets and outlets for alternately directing the media through the sections, a common housing in which the sections are arranged in their spaced relationship, each of said sections being composed of substantially parallel thin sheets which co-operate in forming a plurality of passages extending between opposing faces of the sheets, said sheets being impregnated with a hygroscopic substance, said sheets having a substantially larger dimension in the surface extension of their iiat sides than in the longitudinal direction of the passages between the sheets, the exchanger body and portions of the housing defining chambers between said body and housing, said chambers being connected in pairs over the exchanger passages, the inlets and outlets including casings connected to the housing, said casings extending transversely across all of the chambers, said casings having openings facing the chambers
  • a regenerative moisture exchanger according to claim 1 and characterized by the fact that the exchanger sections are spaced from one another with their flat faces directed toward one another, the chambers being ar- 30 ranged in pairs in the intermediate spaces between the sections.
  • a moisture exchanger according to claim 2 characterized by the fact that one pair of casings is arranged on each of two opposing short sides of the exchanger sections.
  • a moisture exchanger characterized by the fact that the inlet and outlet casings connect to fans and are so arranged with respect to the chambers that two gaseous media pass simultaneously through the passages of the sections in counter-current relationship.
  • a moisture exchanger characterized by the fact that the inlet casing for the air which is to be dried is connected with the pressure side of one of the fans while the outlet casing for the regenerating stream is connected to the suction side of the other fan so that a higher pressure will prevail in those sections where the drying takes place as compared with the sections which are simultaneously regenerated.
