Definitions

  • the invention also comprises a method for filling such a boiler-absorber with salt.
  • absorption and absorber are to be understood to include also adsorption and adsorber
  • salt is to be understood as a substance capable of absorbing a gaseous refrigerant and of releasing the same.
  • boiler-absorbers of this type In the manufacture of boiler-absorbers of this type it is customary to fill the space reserved for the salt only about ,4; full so that the salt is thus at liberty to swell up freely as it absorbs the refrigerating medium. Owing to this practise the boiler-absorbers are of large dimensions and the conduction of heat within the salt is very imperfect.
  • the present invention goes a stage further in reducing the cubic capacity of the boiler-absorber whereby in addition to saving of material there is also gained the advantage of adequate heat conduction in all functioning phases and this implies a more rapidly and efficiently working boiler-absorber.
  • the boiler-absorber of the present invention is, as a characteristic feature of same, filled with so much salt that, even after the refrigerating medium has been expelled, a pressure is still exerted on the salt whereby it is kept compressed within a volume smaller than that which it tends to occupy.
  • the standpoint referred to above according to which the cubic contents of the boiler should be equal to the combined volumes of the salt, the cooling medium and the pores has proved to be fallacious, because, by my invention the volume of the boiler is reduced to less than the combined volumes of the salt deposited in its densest form and of the maximum quantity of absorbable refrigerating medium in either the solid or liquid -form.
  • the filling charge can be estimated at 4-8 gram-molecules or more per litre of boiler-absorber volume. If the absorption medium consists of a halogen salt, the most advantageous filling charge is 5-6 gram-molecules per litre of boiler-absorber net volume.
  • strontium chloride weighs 159 kg. and in its densest form occupies a volume of litres. According to the idea hitherto prevalent among technical experts a boiler-absorber volume of 436-486 litres is requisite for this quantity of salt. If we suppose that the operation is carried on with 5 kilogram molecules NHz in circulation, then it has been considered possible to reduce this volume to 336 litres.
  • One kilogram molecule of SrClz absorbs, for example, 8 kilogram molecules NH: which weigh 136 kg. and occupy in the liquid form a volume of 220 litres. The volume of the ammonia in the solid form is 176 litres.
  • the sum of the volumes of the salt and the ammonia is 280 litres when unconibined if the ammonia is in liquid form, or 236 litres if the ammonia is in solid form resulting in densities of the salt of 3.5 and 4.2 gram-molecules, respectively, per litre net volume of boiler-asborber.
  • the cubic capacity of the boiler-absorber is made molecule of SrCl: was 336 litres and, of the 8 kilo-- gram-molecules of ammonia having a weight of 136 kilograms, it has not been possible to circuate more than five-sevenths of this amount, or 97.1 kilograms.
  • the volume of the boiler-absorber is, according to the present invention, reduced to or 46% .of what has heretofore been regarded as the minimum boiler-absorber net volume.
  • One kilogram molecule or 247.5 kg. has a volume of 60 litres and 8 kilogram molecules of NH: in solid form, have avolume of 176 litres.
  • the boiler-absorber volume according to the invention is 236 litres at the utmost andmay be'a'ppropriately 188 litres,
  • the minimum volumes cited for the absorption media are those'which they occupy in the entirely compact or fused condition.
  • the boiler-absorber is conveniently filled with salt in a finely pulverized form free of water and then the salt occupies a volume substantially greater.
  • pulverized strontium chloride for instance, has a specific gravity of approximately 1.0.
  • For each litre of boiler volume it will be convenient to have a charge of 5.3 gram-molecules or 850 grams which, in powder form, thus takes up a volume of 850 cmfi, that is to say, the net volume of the boiler-absorber is filled 85% full with salt in powder form.
  • the requisite boiler-volume should thus be 340 litres.
  • One kilogram molecule of CaCla can combine with 8 kilogram-molecules of NH: to form CaCl:.8 NH: and the total volume of the salt and of the refrigerant. when uncombined, is 272 litres if the refrigerant is in liquid form, and 228 litres if the refrigerant is in solid form.
  • These two figures represent the greatest net volume of the boiler-absorber according tothe invention.
  • the most convenient boiler-absorber net volume is, however, 130 litres and thus the charge is more than 3.7 or 4.4 gram-molecules and preferably 7.7 gram-molecules of salt per litre net volume of boiler-absorber.
  • lithium chloride LiCls is selected as the absorption medium and methylamine CHaNH: as the refrigerating agent, then the following values are" arrived at.
  • One kilogram molecule LiCl: weights 42.4 kmand has a volume of 20.4 litres: it may combine with 3 kilogram-molecules of 083118: weighing 93 kg. and occupying in liquid form 'a'volume of 136 litres.
  • the net volume of the boiler absorber is then selected at 156.4 litres as maximum whereas the of the boilers now in vogue is 203 litres.
  • methylamine as the refrigerating agent. is obtained, by similar reasoning, a boileraheorber volume, according to the invention, 03, 382 litres per kilogram molecule of absorptim at'the utmost while with known boiler-absorbers the corresponding figure is 515 litres.
  • One of the features of the invention is, further to provide construction for the boiler-absorber that will lend itself readily to mass production and into which it will be possible to introduce, in a single operation, the quantity of absorption medium specified above.
  • This is, according to the invention, effected by dimensioning and forming the trays in such a manner that the boiler is filled to the extent desired when the trays are completely filled.
  • An intermediate space is suitably left between the trays and the cover, this space being of such dimensions that the trays occupy only (so-9.5% and, preferably, 80-00% of the cross section area of the recess in the boilerabsorber that is intended for the salt.
  • Fig. 1 shows a first form of practical construction in a vertical section
  • Fig. 2 is a section taken on the line II-II of Fig. 1
  • Fig. 3 shows a detail in plan view
  • Fig. 4 is a view similar to Fig. 2 of a slightly modified form of construction.
  • Fig. 5 is a vertical section through another form of construction and Fig. 6 is a section taken on the line VI-VI of Fig. 5.
  • Figs. 1 and 2 denotes an inside pipe through which hot gases are intended to flow for the heating of the boiler-absorber, or in which it may be intended to fit an electric heater.
  • 4 denotes a pipe coaxial with the former, which together with pipe 2 encloses an annular space suitable for containing a cooling agent during the absorbing periods.
  • a plurality of trays 6, in the form of annular discs provided with inner and outer flanges 8 and I0, respectively. are arranged axially behind one another along the pipe 4 with the free end of the outer flange In on one tray engaging the body of the next tray to form a series of annular salt pockets.
  • the inner flanges 8 bear tightly against the pipe 4 with a view to producing a satisfactory heat-conduction between trays 6 and the cooling agent in the space between the pipes 2 and 4 and also between the trays 6 and the hot gases in pipe 2.
  • the inner flanges 8 of the trays 6 may have internal screw threads engaging external threads on the pipe 4.
  • two stay-plates l2 and I4 rigidlysecured to pipe 4 and serving to take up the axial pressure exerted by the salt, said stay plates holding the salt together with the trays in a package so that the volume of said package will remain fixed throughout the heating and cooling periods of the boilerabsorber.
  • stay plates have been shown in the form of discs, obviously other suitable means may be provided for the same purpose.
  • apertures are provided in the stay-plate l2 through which the refrigerating medium flows.
  • the cylindrical mantle forming the cover of the boiler is denoted by Hi, and denotes its two end plates which, owing to the presence of the stay-plates l2 and M, are not exposed to axial pressure.
  • the outer flanges IU of the trays 6 bear tightly against the mantle IS.
  • the depth or thickness of each salt pocket formed between adjacent trays is 5 mm. as maximum but should, preferably, not be less than 3 mm.
  • each tray may be provided with an opening through which the salt may be introduced into each pocket prior to insertion of the entire package of trays into the cover Hi.
  • further three symmetrically distributed holes 26, 28 and 30 which constitute channels extending longitudinally in the boiler, and are intended to facilitate the passage of the gaseous refrigerating medium to the different pockets of the'salt package.
  • a metallic cloth 32 is inserted between it and the adjacent tray, as clearly shown in Figs. 1 and 5.
  • the pipe 34 leading to the condenser of the refrigerating apparatus discharges at the one extremity of the boiler-absorber into a special chamber 36 within which any liquid refrigerating agent which may flow back towards the boiler-absorber is collected and prevented from coming into contact with the salt which would tend to lower its absorption capacity. This liquid then evaporates in the chamber 36 and the salt pockets are, in this way, protected.
  • the procedure is, first, to fill the pockets formed by adjacent traysfi completely with a dry salt such as, for instance, strontium chloride in pulverised and water-free form, before the cover has yet been put on.
  • a dry salt such as, for instance, strontium chloride in pulverised and water-free form
  • the portion of the salt in each pocket which may be considered as having the same cross-sectional shape as the excision 22 is then removed, by, for instance, ejecting it with a special tool inserted axially through the salt pocket.
  • a quantity of salt which, reckoned as a percentage is approximately equal to the percentage that excision 22 forms of the cross sectional area of the space in the boiler-absorber designed to contain the salt, or, say, roughly 15%.
  • the space in the boiler-absorber provided for the salt package is thus about 85% full while the residual space is available for swelling.
  • the salt is then saturated with the cooling-medium, such as ammonia, causing it to swell up and fill the aforementioned space in the boiler completely, so that the salt fills up the excisions 22 also.
  • the salt is thus so intensely compressed that, even when the ammonia is subsequently driven ofi and completely disappears, the space in the boiler provided for the salt remains completely fills and the salt package takes up a fixed position in the boiler from which it will not be shifted as a result of the diminution in volume occasioned by the expulsion of the cooling agent, as is the case with certain known types of boiler.
  • th trays 6 have a portion linearly cut off along a straight line so that a longitudinal channel 22 is formed between them and the cover I6 once the central pipe 4 and the package of trays secured thereto have been inserted in the cover I 6.
  • the sections cut away are of such size that the channel 22' forms 10-20% of the cross-sectional area of the boiler-absorber.
  • the tray is here constructed with a diameter smallerthan cover it so that a clear annular space is left between it and the cover it coaxial therewith.
  • the outer flanges II) are cut away at 24 and by means of apertures so formed, the trays can be completely filled.

  • cadmium nitrate Cd(NOs) z ammonium nitrate NH4NO3, or ammonium thiocyanide NHiSCN.
  • Finely divided metals such as iron filings may also be employed for this purpose.
  • the net volume of the space provided for the salt has not been completely filled as from 10 to was left free. in certain instances it may be desirable to mix the salt with a substance or substances other than the refrigerant and to add enough of such substance or. substances to the salt so that the mixture will completely fill up the net volume or the boiler-absorber.
  • the addition substance or substances can be driven out, for example, by heating up the boiler-absorber. Th substances used for this purpose must be of such composition that the chemical and physical properties of the salt are not aflected thereby.
  • Such addition substances can be water, alcohols or other liquids.
  • Solid bodies can also be employed, and especially those that pass directly into the gaseous form, such for example, a camphor, salamoniac, ammonium carbonate, bicarbonate, etc.
