Definitions

  • this invention relates to a method in the manufacture of an exchanger packing composed of elements, such as thin layers or sheets which directly or possibly indirectly by means of distance pieces bear against one another at mutually spaced places and therebetween form passages open from end to end and extending through the packing.
  • elements such as thin layers or sheets which directly or possibly indirectly by means of distance pieces bear against one another at mutually spaced places and therebetween form passages open from end to end and extending through the packing.
  • elements such as thin layers or sheets which directly or possibly indirectly by means of distance pieces bear against one another at mutually spaced places and therebetween form passages open from end to end and extending through the packing.
  • elements such as thin layers or sheets which directly or possibly indirectly by means of distance pieces bear against one another at mutually spaced places and therebetween form passages open from end to end and extending through the packing.
  • the layers usually at least every second is corrugated, the places of mutual contact of the layers being formed by the ridges of the corrugations.
  • the layers are to advantage constituted of sheets or foils of a fibrous material which preferably is non-metallic and inorganic as is the case with asbestos.
  • An essential field of use of the invention is the transfer of moisture and/ or heat, in particular between two air currents.
  • the exchanger packing preferably has the structure of a rotor adapted to move along a closed path between two pass-ages t-ransgressed by the two air currents.
  • One main object of the invention is to provide an exchanger packing in which the layers have high mechanical strength, especially in wet condition which latter condition is actual when the exchanger packing during its operation comes into contact with a liquid such as water.
  • Another object of the invention is to provide an exchanger packing possessing hygroscopic properties and a high drying effect. These two objects may be aimed at by the exchanger packing of the invention either separately or in combination.
  • the invention involves such a processing which has as its distinctive feature of impregnating the layers with a composition of matter in liquid state of such kind as to form a gel which thereupon is concentrated by evaporation until a solid substances remains on the layers.
  • the composition of matter is of a kind containing silicon or a silicic acid compound so that the deposit remaining after the concentration is constituted by a silicon dioxyde substance.
  • the layers are of a fibrous material such as asbestos which in itself has an insuflicient wet strength, the impregnation according to the invention imparts to the layers a fully sufficient strength.
  • a heat treatment at a lower temperature such as at 200 C. or therebelow imparts to the silicon dioxyde a reversible function so as to some extent to be restorable into its gel condition it will at 'a higher temperature such as up to 600 or 700 C. be more and more anhydrous and at the same time stable as to its composition.
  • the silicon dioxyde will no longer be capable but to a limited degree to pick up moisture, but it is at the same time practically water-insoluble.
  • FIGURE 1 is a section taken along the line II of FIGURE 2.
  • FIGURE 2 is a section taken along the line IIII of FIGURE 1.
  • FIGURE 3 shows the apparatus in external projection partly in section taken along the line III-III of FIG- URE 2.
  • FIGURES 4 and 5 are fragmentary sections showing alternative forms of construction of the rotor mass.
  • reference numeral 10 indicates a casing which may be connected to a horizontal support by means of a flange 12.
  • the motor 14 may be mounted directly on the casing 10 and is provided with a shaft 16 which rotates in the sleeve 18 extending inwardly from the casing.
  • the sleeve supports the rotor, generally indicated at 20, and may have a hub portion 22 and a rim portion 24 between which a spirally wound web is supported.
  • the web is preferably made of nonmetallic fibrous sheet material, such as cellulose or asbestos paper and the like of of paper modified by asbestos fibers, glass fibers, plastic fibers and others.
  • the sheets may be as thin as millimeter.
  • the motor or sorption mass is built up to form alternate flat sheets 30 and corrugated sheets 32 shown in FIGURE 5 of the drawing. It may also be composed of sheets 26 spaced apart by ridges 28 as shown in FIG- URE 4 or may have a honeycomb form.
  • the distance between the fiat sheets, or in other words, the height of the corrugations in sheet 32 may vary for particular conditions of application.
  • the fiat and corrugated sheets 30 and 32 divide the packing into a plurality of closely adjacent cells or passages open at both ends at opposite sides of the wheel and extending axially therethrough.
  • the fiat sheets When the packing is used in an air conditioning system, as a transferrer of thermodynamic characteristics of air, the fiat sheets may be spaced from one another less than 3 milimeters and preferably less than 2 millimeters.
  • the wheel 20 when acting as moisture transferrer is rotated at a very slow rate of speed, such as on the order of l to 10 revolutions per hour.
  • a very slow rate of speed such as on the order of l to 10 revolutions per hour.
  • one of the air streams such as that from an enclosure, is impelled through the duct 34 into the compartment 36 by means of the fan 36 and blown through the passages or cells formed by the flat and corrugated sheets 30 and 32, into the compartment 37 and hence exhausted through the duct 38.
  • Another air stream such as outdoor fresh air, is drawn by fan 44 through the duct 40 into the compartment 39, through the passages of the Wheel 20 at the right hand half thereof and counter current to the air stream flowing through the passages in the left hand half of the wheel; hence into compartment 41 and through the duct 42 to the enclosure to be conditioned.
  • compartments 35 and 41 are separated from one another by means of a partition 46- (FIGURE 3) while compartments 37 and 39' are separated from one another by means of partition 4%.
  • Partition 4% may be attached to a cover which can be removed to provide access to the wheel. The wheel may be removed from the casing by first unscrewing the nut 52 from the shaft 16.
  • stationary sealing elements 54- and 56 may be arranged in the casing at the faces of the wheel.
  • these sealing elements comprise a corrugated structure having large passages relative to the passages in the rotor mass.
  • sealing elements may also be mounted on the edges of the partitions 46 and 48 to bear against the faces of the wheel.
  • Such sealing elements may be in the form of shoes mounted on the edges of the partitions 46 and 48 and yieldingly pressed against the sides of the wheel.
  • the bonding together of the sheets or foils at the places of contact may be effected by means of conventional methods and glueing agents, preferably of inoganic kind such as water glass.
  • glueing agents preferably of inoganic kind such as water glass.
  • the bonding may even at least partially be made by means of the gel. If the packing is assembled of so-called single-well webs which are wound in layers one upon the other the one plane and one corrugated strip of the web may be bonded together by means of water glass or the like in the machine for manufacture of single-well.
  • the individual webs of the assembled single-well web structure may then be glued to one another by the treatment according to the invention.
  • the layers may be constituted by a carrier of a ceramic, possibly porous material which has been heated to sintering temperature so as to obtain a solid, coherent structure.
  • the impregnation according to the invention may according to one embodiment of the invention be carried out by means of an organic silicic acid compound, preferably ethyl silicate or silicic acid esters.
  • organic silicic acid compound preferably ethyl silicate or silicic acid esters.
  • ethyl silicate or silicic acid esters When such compound is brought into contact with or absorbs moisture it assumes a gel-like state. Thus the layers or sheets of the exchanger packing are covered with the compound and thereupon exposed to the action of the moisture. Simultaneously with the formation of the gel alcohol escapes.
  • water commences to be driven out from the gel and gradually a solid cover comes into existence. This cover contains silicon dioxyde and some water. This process is accelerated by increase of the temperature. Up to some predeterminable temperature the solid cover may be restored to the gel state by picking up of water to some extent, but by further increase of the temperature the silicon dioxide assumes a more and more irreversible state and thus becomes stable.
  • the layers, such as the asbestos sheets are initially impregnated with water glass and subsequently with an acid such as hydrochloric acid or sulfuric acid whereby a gel is produced as a product of a chemical reaction. Residues of the acid and other soluble reaction products are removed by rinsing with water provided that the cover of gel on the sheets permits it.
  • the gel may be subjected to a partial drying treatment prior to said rinsing procedure. The gradual concentration of the gel by evaporation is continued in the same manner as described hereinbefore.
  • the reinforcement imparted to the fibrous carrier is dependent on the glueing capacity of the precipitations on the fibers, said capacity becoming better with increase of the quantity of silicon contained in the starting substances for the impregnation.
  • the proportion between the silicon and alkaline constituents in the water glass must be of an order of magnitude of at least 3:1, especially in the acid method. This does not imply that the concentration of the two substances necessarily must be high; rather diluted water glass may be used. At all events the acid concentration must be so high that the silicon dioxide cannot take colloidal state instead of being formed as a gel.
  • solubility in water of the precipitated silicon dioxide is in relation to the reversibility of the capacity to pick up water imparted to the silica gel.
  • a concentration by evaporation of the gel at relatively low temperatures increases the water-solubility.
  • a concentration by evaporation at relatively high temperatures reduces the Watersolubility but also the strength and the glueing capacity. This implies that the precipitated silicon dioxide becomes brittle or fragile upon treatment at high temperatures, in particular when all water has been stripped.
  • the mechanical strength of the individual layers is of importance one must always adjust the upper limit for the heat treatment to a predetermined value so as to meet the requirements of mechanical strength.
  • potassium water glass produces together with sulfuric acid as a reaction product potassium sulfate which is distinguished from sodium sulfate by not containing any crystal water.
  • potassium water glass may be of advantage.
  • asbestos sheets often contain not only filaments of asbestos but also a bonding agent for the fibres of organic nature such as starch, for example.
  • a bonding agent for the fibres of organic nature such as starch, for example.
  • an oxidation or degassing of the organic bonding agents is performed under which procedure attention must be paid to the temperature in the asbestos fibres which temperature must not be increased so much as to cause them to set their crystal water free and therewith to lose their mechanical strength.
  • Such a treatment may without difiiculty be combined with the treatment according to the present invention, the stabilization of the deposit of silicon dioxide on the fibres being. effected simultaneously at a highest possible temperature below the temperature critical for the asbestos fibres.
