Definitions

  • the present invention refers to an apparatus for transforming long molecular chain organic matter.
  • mixtures of organic compounds of low molecular weight constitute the basic components of the fuels used to power vehicles such as aircraft, automobiles and the like.
  • Thermal scission techniques for implementing such transformation are therefore widespread: these techniques break the carbonaceous bonds using heat, which is applied to the material to be processed both from outside, and by means of combustion of part of the very material to be processed.
  • transformation plants that include a cylindrical chamber inside which the material is mechanically mixed, shredded, crushed, and ground. This causes the material to assume a viscous consistency and subjects it to forces of friction that are such as to increase its temperature and pressure, so producing the desired breakage of the molecular bonds.
  • This embodiment is also, however, not without drawbacks.
  • the aim of the present invention is to solve the above mentioned drawbacks, by devising an apparatus that makes it possible to achieve the transformation of long molecular chain organic matter with a solution that is structurally simple.
  • an object of the invention is to devise an apparatus that can cause the transformation of long molecular chain organic matter without imposing high operating speeds upon the elements involved.
  • Another object of the invention is to devise an apparatus that can operate in total safety, without risk of blowouts and explosions.
  • a further object of the invention is to devise an apparatus that ensures a high level of reliability in operation.
  • a further object of the invention is to devise an apparatus that can be easily made from elements and materials that are readily available on the market.
  • a further object of the invention is to devise an apparatus that can be made at low cost and applied safely.
  • an apparatus for transforming long molecular chain organic matter comprising at least one chamber that has at least one conduit inside it which is interposed between at least one inlet, for the introduction into said conduit of long molecular chain organic matter, and at least one outlet, for the expulsion of short molecular chain organic mixtures, obtained from the transformation of the long chain organic matter, characterised in that at least one active portion of said conduit is delimited by respective surfaces of at least one pair of rotors, arranged at least partly side by side inside said chamber, and, at said active portion, the simultaneous rotation of said rotors subjecting the long molecular chain organic matter to mechanical stresses, with consequent increase, due to friction, of the temperature and internal pressure, for the breakage of the long molecular chains.
  • Figure 1 is a plan view of an apparatus according to the invention.
  • Figure 2 schematically shows the operation and the motion of the rotors, at the active portion of the conduit.
  • an apparatus according to the invention is adapted to transform long molecular chain organic matter and comprises at least one chamber 2, inside which the transformation takes place.
  • the chamber 2 has at least one conduit 3 inside it, interposed between at least one inlet 4a, which allows the introduction into the conduit 3 of the long molecular chain organic matter to be transformed, and at least one outlet 4b, which allows the expulsion of the short molecular chain organic mixtures, obtained from the transformation of the long chain organic matter.
  • the long molecular chain organic matter that can be transformed by means of the apparatus 1 according to the invention can be any: by way of example, it is possible for it to be residues of plastic materials, polymeric materials (vulcanised rubber, thermoplastics etc., such as used tyres), vegetable flours, doughy or semi-liquid products, and so on.
  • the possibility of employing the apparatus 1 according to the invention for the transformation of different types of organic matter is not excluded.
  • At least one active portion 3a of the conduit 3 is delimited by respective surfaces of at least one pair of rotors 5, arranged at least partly side by side inside the chamber 2.
  • the simultaneous rotation of the rotors 5 subjects the long chain organic matter to mechanical stresses, which produce, by friction, a consequent increase in the temperature and internal pressure, capable of causing the breakage of the long molecular chains.
  • the above mentioned organic matter is subjected to mechanical stresses of various different types, as an effect of the simultaneous rotation of the two rotors 5: the matter, in fact, is stretched, crushed, milled, shredded, ground and so on.
  • the forces of friction, internal and external, generated between the various different layers of the organic matter present thus raise its pressure and the temperature of the matter until it produces the breakage of the long molecular chains, and the desired transformation of the organic matter introduced into the chamber 2 into short molecular chain organic mixtures.
  • the transformation achieves the separation of the respective solid, liquid and gaseous phases, which then exit from the outlet 4b.
  • the rotors 5 are substantially constituted of cylindrical shafts located side by side, which rotate in the same direction (with equal or different angular speeds) about respective axes, which are substantially parallel to the axis of the chamber 2 and inside thereto.
  • the chamber 2 is also preferably cylindrical in shape.
  • each shaft has at least one first upstream section 5 a and at least one second downstream section 5b: the active portion 3a of the conduit 3 is delimited by the downstream sections 5b of such shafts, which are arranged side by side and are proximate and substantially parallel.
  • the chamber 2 comprises two inlets 4a that feed into respective accommodation seats 6 of corresponding upstream sections 5a of the shafts: the spaces that are thus delimited by each of the upstream sections 5a and by the respective seat 6, constitute respective head branches 3b of the conduit 3 (which is therefore substantially Y-shaped), such branches feeding into the active portion 3 a.
  • each upstream section 5a of the shafts is substantially constituted by a first screw, the spiral 7 of which, wound around the stem of the shaft, is adapted to drag along the spaces the long molecular chain organic matter to be transformed (introduced into the branches 3 b through the inlets 4a).
  • the diameter of the downstream sections 5 b is greater than that of the upstream sections 5 a to obtain, precisely at the opposite-facing surfaces of the rotors 5, the maximum tangential speeds (and the maximum stresses), while along the upstream sections (smaller in diameter) the organic matter is simply dragged (and possibly preheated).
  • the lateral surfaces of the downstream sections 5b are substantially flat, and the section of the downstream sections 5b has a greater diameter than that of the upstream sections 5a, in order to obtain, at the active portion 3 a, greater tangential speeds (useful to the transformation of the organic matter).
  • the downstream sections 5b of the shafts are constituted by second screws (the pitch of which is the same as, or different from, that of the first screws already described), to produce the dragging of the organic matter being transformed along the active portion 3a. Also according to this embodiment, there is the possibility that the downstream sections 5b of the shafts have a greater diameter than that of the upstream sections 5 a, to increase the tangential speed.
  • Such organic matter can thus travel along the branches 3 b of the conduit 3, possibly pushed by the first screws which constitute the respective upstream sections 5 a of the rotors 5.
  • the organic matter can thus arrive at the active portion 3 a, in which, as shown previously, it is subjected to mechanical stresses that are such as to induce the breakage of the long molecular chains that compose it, thus obtaining the desired transformation into organic mixtures of various types, with short molecular chain.
  • the action of the two rotating surfaces makes it possible to maintain a low speed of rotation for the two rotors 5 (and consequently greater structural simplicity of the entire apparatus 1), but at the same time it ensures that stresses and frictions are obtained to an extent that are such as to guarantee the accomplishment of the desired transformation of the organic matter into short chain organic mixtures.
  • the organic mixtures obtained in the chamber 2 can then exit from the outlet 4b and be collected in suitable containers (and possibly undergo further refining treatments, according to the specific uses to which they are destined).
  • apparatuses 1 that are provided with three or more rotors 5, arranged for example side by side to define a plurality of active portions 3 a, or even having different shapes, possibly also in such a way that at least three rotors 5 contribute (with respective surface areas) to delimit the same active portion 3 a, should this be considered preferable according to the specific application needs.
  • the apparatus according to the invention fully achieves the intended aim, since the transformation of the long chain organic matter occurs in an active portion of a conduit that is delimited by the simultaneously rotating surfaces of at least two rotors, and this subjects the organic matter to mechanical stresses that are such as to induce their transformation into short molecular chain organic mixtures, with a structurally simple solution.
