- figure number 4 it has been represented as an inventive antecedent and presented as a Utility Model in Spain with the number 9402456, a first version, in which the plates had a certain concavity where molten polyethylene was maintained, while the Aluminum sheets would fall through holes that communicated each plate with the one below and, from the last one, by means of an endless screw, the aluminum was taken outside.
- the oven is fed from a hopper through of an auger that discharges into a cylindrical housing (3), inside which there is a series of cylinders or floors of greater diameter and height, whose lower cover is preferably flat, and the upper concave, preferably in Inverted cone shape, these plates having a cylindrical orifice (22) with a diameter slightly larger than the shaft, through which it drains, lowering the oil formed in the non-distilled pyrolysis down to the shaft, while the leaves made of aluminum (covered or not with polymer), they fall to the lower floor through a slot d preferably trapezoidal, and these grooves are displaced an angle from the upper one of about 30 °, although in the drawing represented in Figure number 6, has been placed at 180 ° to facilitate its understanding, that is, diametraimente opposite, in order that the product that falls to a floor, before lowering the next, has to cover its entire surface.
- each floor cylinder
- the flue gas circulates that allows the heating of its surface that is transmitted to the polymer coated aluminum sheets.
- Figure number 1 Corresponds to a scheme of the oven described by Yoshida in US 3984288.
- Figure number 3. Shows a block diagram of the process covered in the present invention relative to a process for the recovery of aluminum and energy, from used "tetrabrick" type containers and furnace to perform it, specifying that the blocks marked with Dotted lines correspond to the previous part of paper removal not included in this invention.
- Figure number 4. Corresponds to a schematic view of the furnace in a previous version, owned by the applicant, requested in its day as a utility model in Spain with the number 9402456, in which it is fundamentally contemplated to keep the products of pyrolysis until its volatilization in each dish, and since this is not completely possible, the aluminum obtained is mixed with such products.
- Figure number 5 Corresponds to a view of the furnace according to the invention, where non-vaporized pyrolysis products are collected in a container intended for this purpose.
- Figure number 6. Shows in detail the plates or floors (the thin arrows indicate the path of the heating gases and the thick arrows the path of the product and the oil).
- Figure number 7. Shows the scheme of the circulation of the product on the plates.
- Figure number 8. Corresponds finally to a three-dimensional scheme of a plate.
- the volatile fraction is used for its energy content by burning it in an oven; This does not create pollution problems, since it is aliphatic and aromatic hydrocarbons without the presence of other elements (essentially halogens).
- the heavy fraction can be used as such (the product is similar to a wax and its applications are similar) or in the same process and in this case, appropriate catalysts would be used, dividing the molecules into smaller ones to give, in greater or smaller proportion, a volatile product that can be burned.
- the aliphatic hydrocarbons that are produced have at least three carbon atoms and almost 85% have chains between 3 and 18 carbon atoms, leaving approximately 10% of the decomposition products with more than 18 carbon atoms .
- n is between 2 and 10.
- the second fraction is important, which reaches up to the n-octodecane has a boiling point limit of 316 ° C and 22 ° C at its melting point; accordingly, this fraction, which can condense all or part of the conduction, remains liquid under normal conditions; therefore, it is easy, by means of an appropriate design of the pipes, to pick it up in a tank for its later treatment.
- long chain hydrocarbons which can account for up to 10% of the total decomposed, have high boiling points, but not their melting points, and therefore can lead to solid products at room temperatures, but with proper heating gives, within the oven, easily manageable liquid products and their collection inside the same oven, allows, as said, to subject them to catalytic cracking or storage for further commercialization.
- the procedure object of this invention is based, consisting of pyrolysis by indirect heating of the polymer coated aluminum sheets so that:
- the volatile fraction can be separated easily.
- the process object of this invention is based on the polymer-coated aluminum sheets remaining as a byproduct of a separation treatment of the cellulosic part (paper) of the tetrabrick.
- the lower plane of the chamber is inclined to collect the heavy fraction of the pyrolysis of the polyethylene and the light fraction is dragged through the use of an inert gas, preferably combustion gases, to a collector for use as fuel, and from this shape, having a sufficiently long path for the product path (aluminum + polyethylene), it can be achieved that in the end an aluminum is practically free of polyethylene.
- an inert gas preferably combustion gases
- the present invention also claims an oven that allows a simple way to carry it out.
- the oven is formed by a series of plates as shown in figure number 8, formed by a cylinder of greater diameter than height, closed by its lower and upper part.
- the upper surface (23), through which the product to be treated is displaced, is concave, preferably in the form of an inverted cone, at whose apex a hole (22) has been drilled, which crosses the lower face (24), which is closed by a cylinder.
- FIG 6 it has been indicated below the upper surface (23) of the plate, an area (25) destined to optionally place fins, roughnesses or any other means that allows to increase the heat transmission of the gas to the heating surface (23).
- the drag of the aluminum sheets is carried out, as shown in figure number 7, by rakes that start from an arm (8), integral with the axis (6), by means of the clamp (21), and the axis It passes easily through the hole (22), leaving enough space for the heavy fraction of the pyrolysis of the polyethylene to drain through it, but not enough so that the aluminum sheets that have no more exit than the slot can pass ( 12), after having traveled the entire hot surface.
- the gases formed in the pyrolysis leave, as shown in Figure 6, through a lateral duct (10) that goes to a manifold (14).
- a container (18) located eccentrically, at the bottom of which, supported by a bearing (17), rests the shaft (6), and to this tank falls, draining down the axis, the non-volatile fraction (oils) of pyrolysis.
- oils or waxes which are chemically fundamentally paraffins and olefins, can be subjected to catalytic cracking in the same oven, introducing a suitable catalyst into the tank and can be taken out of the oven for direct use as such or its treatment chemical suitable to obtain, via synthesis, aromatic hydrocarbons of high value.
- the present invention only contemplates the physical possibility of performing such an operation "in situ".
- the invention contemplates a certain tightness of the system, for which a sufficient closure of the three key points of the equipment, two of them constituted by the feeding of the product and the exit of the aluminum and the third is the passage of the axis, is foreseen.
- the feeding is done through a hopper (1), which unloads in an auger screw (2), by heating the product until it reaches about 100 ° C, producing at first a drying (the water vapor goes back into the hopper), and in the end, a fusion of polyethylene.
- the exit of the aluminum takes place after its fall, through the last slot (12), located diametrically opposite to the box (18), in a hopper formed by the bottom of the oven, and from this hopper, an endless screw (19). it is removed to the outside, closing by the compression made on the sheets made by the last part (20) of the screw.
- a closing box (7) a drag arm (8), a plate (9), the gaseous fraction outlet (10), the heating gas outlet (11), the drop slot (12), the communication chimney (13), the gas fraction collector (14), the drag gas (15), the gas discharge pump (16), the bearing (17), the tank of heavy fraction (18), the auger (19) and the compression zone (20).
- a clamp (21), a drop hole (22), the upper face of the plate (23), the lower face of the plate (24) are incorporated in the margin of some elements already referenced in the previous figure ) and the fins or rough area of optional application (25).
