Definitions

  • the present invention relates to a method for pyrolytic decomposition in a pyrolysis reactor intended for continuous operation comprising, supplying the material towards the pyrolysis reactor, pyrolysing the material in a pyrolytic process in the pyrolysis reactor in the absence of air, removing gas released by the pyrolysis process, and removing residual products resulting from the pyrolytic decomposition, such as slag. It also relates to a corresponding pyrolysis arrangement .
  • Gas generators for segregating combustible material are well known, not least in the form used previously and they are still used in certain plants for the production of town gas, for example.
  • the basic concept itself is the same, namely anaerobic segregation at increased temperature, and the handling of released gas and residual products.
  • a pyrolysis reactor is loaded with a set of pyrolysable material which is then heated under oxygen-free conditions at the same time that the gas released during the process is handled.
  • the pyrolysis reactor is hermetically sealed to avoid explosive processes. Prolonged cooling is thereafter required to bring down the temperature in the gas generator to such a level that the residues remaining after pyrolysis do not spontaneously ignite when free oxygen penetrates as the pyrolysis reactor is being opened. This is not, nor has it ever been, a particularly good process, not least because it involves extensive handling relating to loading, heating and cooling. It is also not energy effective.
  • the operating or driving speed or rotation frequency of the second motor can be preset to a given value depending on material properties, e.g. density etc. In an advantageous embodiment it is also set depending on operation temperature and depending on capacity of the pyrolysis arrangement (e.g. reactor and feeding means) .
  • the speed/rotation of the second motor is set to a constant value whereas the speed/rotation of the first motor (or motors) is regulated depending on the measured (current) value of the compression (density) or the pressure exerted e.g. on a wall as discussed above.
  • a computer controlled control means connected to the detecting means continuously or with a given frequency receives information concerning a measured quantity and controls the first motor (e.g.
  • the control function is also adapted to switch it on after a stop, lowering the speed, and particularly after a stop, gradually increasing the speed. Normally an even compression is desired, e.g. a given degree of compression. It is apparent that for example since the density of tyres or rubber differs a lot from e.g. that of foam or similar, if there is a slight (unintentional or intentional) mixture of materials, this will have considerable effects on the compression or pressure related features.
  • the detecting means is arranged in the upper part of the second channel or pipe, between the two conveyor screws, to obtain measured values which are not affected by the screws, e.g. by scrapping material in the direct vicinity of the detector.
  • a detector or a sensor may be arranged between the or each pair of conveyor screws. Then two or more current values may be obtained and a mean value or an optimized value may be provided which enables an even more accurate control of the first motor.
  • a (each) detector is arranged opposite to, and above the "inlet" from the first conveyor. Also if there is only one second conveyor or if there are two second conveyor screws, one or more detectors may be used to assure that extremely accurate values are obtained. Particularly a constant compression is obtained all the time, and it is aimed at having the second feeding means, and the screw threads, full with material all the time.
  • the material intended for pyrolysis is fed by means of the first screw conveyor to a conveyor unit which in an advantageous embodiment comprises two screw conveyors rotating in the same direction.
  • the conveyor unit comprises three or more screw conveyors, which preferably are arranged in parallel in a tube or channel.
  • the material intended for pyrolysis can be compressed so that all the air and oxygen bound by it is pressed out. The compression can be even more favoured and the propulsion of the material even more simplified because both, or all of, the conveyor screws of the conveyor unit rotate in the same direction.
  • the screw conveyor or conveyors of the second unit may be driven at a higher speed that the first screw conveyor, at least occasionally, since the result of the measurements may lead to a lowering of the speed, or even a switch off of the first motor, and hence the first screw conveyor (s).
  • the screw (s) of the first conveyor is in an advantageous embodiment driven at a higher or equal speed than the second screw conveyor (s), or so driven that the flow of material is higher per unit of time than for each of two or more second screws.
  • the second conveyor unit comprises two screw conveyors that are driven at different speeds. This enables a higher degree of compacting to be achieved than otherwise, thus providing even better sealing than would otherwise be the case.
  • the screw conveyor in the conveyor unit that has the higher speed is nevertheless, preferably, or most of the time, driven at a speed that is lower than the speed of the first screw conveyor .
  • material is fed, according to a further embodiment of the invention, to an openable shutter at the feed-in end of the pyrolysis reactor during an introductory phase of the continuous feeding of material.
  • the shutter favours the build-up of a plug of pyrolysable material translatable by means of the screw conveyors and, after an introductory phase, it can be kept open as long as the reactor is being driven and material is fed continuously and it thus has no other function than as a shutter during the reactor heating process.
  • a gas can be supplied which is lighter than air or oxygen, preferably nitrogen, to the upper section of the supply means (e.g. the second feeding channel) , so that as a result of the mass ratio between the gases, all air and any free oxygen can be successively forced out of the supply means in a direction opposite to the conveying direction of the pyrolysable material. Since the first feeding channel or pipe is arranged sloping upwards, i.e. inclined, the supply means will operate approximately in the same way as a traditional water lock, but instead with nitrogen gas.

  • Fig. 3 shows a scrubber with an inlet for gas from the pyrolysis reactor.
  • Fig. 1 schematically illustrates a pyrolysis arrangement comprising a pyrolysis reactor 100 for continuous operation. It should be noted that the entire pyrolysis reactor 100 is suitably arranged at an angle of inclination of approximately 5° with respect to the horizontal plane.
  • a feed hopper 1 At the feed-in end of the pyrolysis reactor arrangement there is a feed hopper 1 in which material, e.g. fragmented car tyres, is fed down.
  • a first feeding means comprising a first screw conveyor 3 arranged in a first channel or pipe and driven by a motor 2, which first screw conveyor 3 propels the fragmented material through the channel which is arranged to form an inclination angle of between 10° and 45° with respect to a horizontal ground plane.
  • the first feeding means screw conveyor 3 in channel
  • a preheating device 5 for heating the material to just above 100°C, firstly in order to expel any moisture containing bound oxygen from the material, secondly to soften the material so that it can be compacted more easily.
  • nozzles for supplying nitrogen gas which, because it is lighter than both air and oxygen gas, will stratify due to the inclination of the feeding means, so that it will expel any air or oxygen gas present at feed hopper 1.
  • a second feeding means with a screw conveyor unit 7, driven by at least one motor 4, and with double conveyor screws which are driven in the same direction of rotation, but at a lower speed than feed conveyor screw 3 (when a second conveyor screw has a smaller screw diameter) , is connected to the upper end of first feeding means comprising the first screw conveyor 3 in the first channel.
  • One end 8 of the second feeding means 6 (second screw conveyor unit 7) is so arranged and connected that it is tightly sealed against the surrounding air some distance into a reactor chamber 9, at an end of which is arranged a shutter 10 which is manoeuvrable between a closed and an open position.
  • shutter 10 upon initiation of a continuous pyrolysis process, is to enable an establishment of an initial press mass of process material from which all the oxygen can be displaced so that it can be removed (driven out) , in the manner described above, to the feed pocket via screw conveyors 3 and 6 respectively.
  • the second screw conveyor unit 7 is followed by a reactor chamber 9, and the press mass falling to the bottom of the chamber will fall out of it onto a slow moving conveyor belt 11.

  • hot zone 13 preferably is demarcated by radiation protection device 16 at the respective ends of hot zone 13.
  • the radiation protection devices are intended primarily to concentrate the heat discharge within the area in hot zone 13 intended therefore.
  • zone 13 After passage through zone 13 there remains a residual fraction of the material intended for pyrolysis which consists mainly of carbon black which, at the end of the conveyor belt, falls down to a screw conveyor 18 arranged in an outlet duct 17 for conveying to an oxygen sealed intermediate store (not shown) , which is emptied instantaneously if necessary.
  • a certain proportion of the material intended for pyrolysis will unavoidably behave in a manner that is not desirable and will either drop down alongside belt 11, or will adhere to this and will therefore possibly spontaneously fall off the same at a later stage, whilst the material is located along the underside of the belt.
  • a detecting device 60 e.g. a pressure sensor, is arranged in the upper part, e.g. at the upper wall of the channel or pipe of the second feeding means comprising (here) a screw conveyor unit 7 in the region where the first feeding means and the second feeding means are joined, i.e. an end of the first channel enters the second channel, where the material conveyed by the first screw conveyer enters the second channel, and from where it will be conveyed by the second screw conveyor unit 7 for feeding into the pyrolysis reactor chamber 9.
  • a screw conveyor unit 7 in the region where the first feeding means and the second feeding means are joined, i.e. an end of the first channel enters the second channel, where the material conveyed by the first screw conveyer enters the second channel, and from where it will be conveyed by the second screw conveyor unit 7 for feeding into the pyrolysis reactor chamber 9.
  • the detector 60 is preferably arranged between (and above) the conveyor screws, see also Fig. 2 very schematically illustrating two second conveyor screws I 2 and an exemplary location of the detector or sensor 60.
  • the first conveyor screw is longer than the (here) two second conveyor screws I 2 and has a larger diameter, e.g. 3-10 cm larger (not shown in Fig. 2) than that of the two second conveyor screws.
  • the diameter of the first screw conveyor may be about 140-200 mm or more (or less), e.g. 170 mm, and the diameter of the second conveyor screws may be about 80-160 mm, e.g. 120 mm.
  • the dimensions may differ a lot from the exemplifying figures and e.g. be several times larger, but also smaller. It should also be noted that the rotational frequencies of the conveyor screws are low, e.g. in the order of size of 1 rotation in 1-20 seconds and a pressure is hence slowly built up in the supply channel (second feeding channel, cf . where the detector 60 is arranged) .
  • a main thing is that the amount of oxygen can be minimized, a constant compression be up-held, and any variations automatically handled by means of the control of the first driving motor.
  • the second channel or pipe is arranged to have a same inclination with respect to a horizontal plane as the pyrolysis reactor 100 (see e.g. Fig. 1) whereas the second channel forms an angle with the second channel, which it enters from below.
  • Fig. 2 shows a pyrolysis arrangement 100 substantially as in Fig. 1, viewed from above. From the left, the first driving motor 2 for the first conveyor screw 3, followed by feed hopper 1 are shown, then first feeding means (first screw conveyor) 3 surrounded by preheating device 5. The first feeding means with screw conveyor 3 connects to second feeding means 6 with screw conveyor unit 7, which is in turn connects to reactor chamber 9 in the vicinity of a shutter 10 at the outlet end of second screw conveyor unit 7.

  • Ducts 17 and 19 respectively, and pipe 21, are provided with an intermediate storage functionality which may require to be emptied occasionally. This takes place, of course, without giving oxygen or air the opportunity, to get in through the "back door” and disturb the process in the pyrolysis chamber.
  • the detector 60 is arranged above the first screw conveyor 3 and between (and above) two second screw conveyors li, 72. The detector 60 provides measurement results to control means 65 controlling the first motor 2.
  • each second screw conveyor 7 ⁇ , I2 is driven by a separate motor; it could also have been a common second motor.
  • the speed of the first screw conveyor is substantially continuously regulated such that an even compression is obtained. It should be clear that the actual speeds depend on the number of screws of a first and a second screw conveyor and the screw diameters and the pitches of the threads.
  • first and second screws have the same diameter and/or pitch, in others the pitch and/or diameter is higher or lower in the first screw, the diameters of two or three second screws may be smaller than that of the first screw etc.
  • Figure 3 shows schematically an arrangement 22 which may be described as a liquid lock or scrubber arranged in a tank or container 23, at the inlet of which tank or container gas from reactor chamber 9 is pumped in to maintain a gas pressure inside reactor chamber 9, which corresponds to the atmospheric pressure of the area surrounding the pyrolysis reactor. The gas passes through a pipe 24 down below a liquid surface so that it is released under the surface and is allowed to diffuse out into a collection device at P.

  • Feed hopper 1 is so large that continuous operation can be maintained without any practical problems.
  • Motor 2 is of such a type that its speed can be varied so that effective compression towards double screw 7 can be guaranteed under all conditions, regardless of the type of material fed in. It is controlled by means of control means 65 (computer controlled) which collects measurement data from detector or sensor 60 and provides a control signal to first driving motor 2 to regulate the speed thereof in dependence of e.g. the detected pressure as discussed above.
  • the speed of the second motor (or motors) 2 is preset depending on material, and optionally also other features, and in an advantageous embodiment the speed of the second motor 2 is lower than that of the first motor unless the first motor has to be temporarily switched off or its speed lowered considerably due to the measured value (e.g. pressure) being too high, also, if there is not enough material (in the second feeding means) it has to be switched off.
  • this material should reach a preheating temperature of 120°C in front of shutter 10 for hot zone 13 of reactor chamber 9.
  • Shutter 10 is here spring loaded to an open position, but is kept closed by a lock (not shown) as long as an oxygen gas detector (not shown) , arranged in the conveyor pipe of second screw conveyor unit 7, indicates that there is oxygen gas in the compression zone of the pipe or in hot zone 13.
  • This oxygen gas detector also controls, by means of a computer (e.g. the control means 65 or another control means) suitable for the purpose and associated software, whether nitrogen gas is to be supplied or not. For example, if a fault occurs in any of the motors 2, 4 driving the screw conveyors, all or some feed-in and heating elements 15 are closed, as is also shutter 10 with positively controlled means (not shown) arranged according to the intended use.
