Definitions

  • the present invention relates to improvements in the processing of materials having an organic component.
  • the method relates to improvements in the processing of such materials in rotating ovens.
  • a further problem of the mass movement of material in this way is that, as the material is often quite dense it will tend to block the flow coming out of the nozzles beneath where it is resting. This results in more of the flow entering the processing chamber from nozzles which are not in direct contact with the material to be processed. This is also disadvantageous as the quickest way to transfer heat from the hot gasses into the materials that are being processed is for the hot exhaust gasses to be injected directly into the materials.
  • a further problem with existing rotating ovens is that when an array of gas outlets is provided around the different sides of the oven and, as described above, the quickest way to transfer heat into the material is to directly inject gas into that material, as the material is located on the lower side of the processing chamber, due to gravity, only a small proportion of the inlet nozzles are capable of directly injecting hot gasses into the material being processed. That is, if as described above, the gas flow from these nozzles has not been prevented by the mass of material sitting on top of them.
  • the processing chamber can be a double-walled chamber that has hot gasses passing between an inner and outer wall thereof so as to heat the inner wall.
  • the materials that are being processed come into contact with this inner wall, then heat is transferred from the exhaust gasses circulating between the two walls into the material by its contact with the hot inner wall.
  • the material within the oven tends to move as a single mass, only a small part of the inner wall is in contact with the waste material at any one time, thereby reducing heat transfer efficiency into displaced material.
  • an apparatus for processing material such as organically coated waste and organic materials including: biomass, industrial waste, municipal solid waste and sludge; the apparatus comprising: an oven having a rotatable portion comprising a treatment chamber adapted to receive material for treatment; a plurality of gas inlets in at least one wall of the treatment chamber through which hot gasses are introduced to the treatment chamber to heat the material therein so as to cause the organic components thereof to pyrolyse or gassify; and at least one retarder means located in the treatment chamber to retard the movement of waste material therein as the oven rotates.
  • the oven has at least one substantially flat side and the retaining means are provided on the flat side of the oven.
  • reaction causing the breakdown of the organic material within the processing chamber will depend upon the processing chamber conditions. If there is zero or substantially zero oxygen present in the processing chamber, then the reaction will be predominantly a pyrolysis reaction. Where there is some oxygen present, there will be a gassification which will include some oxidation. In either reaction a gas will be produced that can be used as described in the prior art.
  • the retarder means to slow the movement of waste material as the oven rotates. Without the retarder means of the invention, an oven having a substantially flat side would rotate until such point that the gravitational forces on the waste material therein overcame the stiction forces resisting movement of that material. Once the stiction forces are overcome then, without the retarder means, the material would move substantially as one solid mass from its current position to a new position substantially at the lowest point of the chamber, sliding across the substantially flat surface.
  • the retarder means slow the movement of the waste material as the oven rotates so that it does not have the same sudden movement as one single mass from one place to another within the chamber but instead moves more gradually.
  • This more gradual movement extends the time period for which the waste material is in contact with the sides of the processing chamber as it passes thereover and increases the surface area of the material being processed. By increasing the surface area of the material being processed, greater heat exchange can take place between the hot gasses and the material.
  • the retarder means can be moved between an active position in which they protrude into the treatment chamber and an inactive position wherein they protrude into the treatment chamber by a lesser amount. In their inactive position the retarders may be substantially flush with the walls of the treatment chamber.
  • the apparatus preferably has an array of retarder means spread about a surface thereof.
  • the retarder means can be moved between their active position and their inactive position to retard the movement of the material within the processing chamber by different amounts as the chamber rotates.
  • activating the retarder means in a rippled effect which may be slowly released from this current position to slide down the chamber walls to a new position at the lower-most point of the chamber.
  • the retarder means are made of spring steel and the retarder means resiliently deform when the retarder means move from its active position to its inactive position.
  • the retarder means may extend through the walls of the treatment chamber and may further comprise actuator means located outside the treatment chamber for actuating the retarder means. This enables the actuators to be maintained in a lower temperature environment whilst still being able to move the retarder means from the active position to the inactive position.
  • the actuator means may, for example, be magnetically driven actuators.
  • the retarder means may comprise a flow path therethrough to enable hot gasses to be introduced into the treatment chamber through the retarder means. In this way, as the retarder means extend from the walls of the chamber, the gas left in the retarder means can be deposited directly into the material being treated as opposed to the prior art systems which only allow heat to be input into the surfaces of the mass of waste being processed.
  • the treatment chamber may preferably have a double wall, comprising an inner wall and an outer wall extending along at least one of its side and its retarder means may extend through both the inner and the outer walls.
  • hot gasses can flow between the inner and outer wall thereby heating the surfaces of the treatment chamber.
  • hot gasses can pass through inlets into the interior of the processing chamber and/or alternatively heated gasses can be passed through the flow paths in the retarder means so as to be deposited into the material within the processing chamber.
  • the retarder means each comprise a plurality of inverted hooks arranged in a radial way about a common central axis with the ends of the hooks based from the common central axis. In this way the retarder may resemble palm trees or the framework of an umbrella.
  • the retarder means in particular the inverted hooks, may each comprise a hollow tube through which hot gas can pass into the treatment chamber preferably with the ends of the inverted hooks are bent so that hot gas emitting from them is directed away from the surface of the treatment chamber. In this way the gas emitting from the ends of the hook shaped retarder means is directed upwards into the mass of waste within the processing chamber.
  • the retarder means can be rotated.
  • the retarder means may comprise a shaft and a retarder head.
  • the shaft can be pivotally connected to the retarder head. In this manner when the retarder is in its activated position, the head of the retarder can rotate under the influence of gravity as the oven as a whole is rotated.
  • a method of processed material such as organically coated waste and organic material including: biomass, industrial waster, municipal solid waste and sludge; the method comprising placing a material to be treated in an oven having a rotatable portion comprising a treatment chamber heating the material in the treatment chamber by introducing hot gasses therein to gas inlets in at least one wall of the treatment chamber; rotating the over so as to cause the material therein to tumble; and retarding the movement of the waste material in the processing chamber by placing the retarder means in the movement path of the waste material.
  • the method further comprises agitating the material in the processing chamber by moving the retarder means between an active position, in which they protrude into the treatment chamber, and an inactive position in which they protrude into the treatment chamber by a lesser amount.
  • the retarder means are repeatedly moved between their active position and their inactive position.
  • This agitation of the material being processed lifts it from the surface on which it is sitting and, by agitating it, provides a constant gas path therethrough so that gas emitted from outlets in the side wall of the processing chamber on which the waste material is sitting can omit from those outlets and pass into, and through, the agitated waste material by agitating the waste material in this way a constant flow of gas is maintained through the gas outlets, even when a relatively large mass of material being processed being present in the processing chamber and located on top of those outlets.
  • hot gases may also be passed through flow paths in the retarder means, thereby directly delivering hot gas into the centre of the material being processed.
  • the method may further comprise rotating one or more of the retarder means.
  • the introduction of hot gas directly into the centre of the waste being processed, together with the retarded movement of the waste material as the oven is rotated results in a far quicker heat transfer into the material being processed.
  • Method preferably further comprises moving to, and retaining in, the inactive position at least some of the retarder means while they are covered with material being processed.
  • retainer means such as the inverted hook type described herein.
  • FIG. 1 shows a rotating oven of the invention
  • FIG. 2 shows a partially cut away chamber of the oven of the invention
  • FIG. 3 shows a isometric view of the details of retarder means in a processing chamber of the present invention.
  • FIGS. 4 and 5 show the movement of the retarder means between its active and its inactive position
  • FIG. 6 shows a further embodiment of the present invention.
  • FIGS. 7 and 8 show diagrammatic views of the movement of material being processed within the oven as it moves both with and without retarder means being provided.
  • the oven 10 comprises a processing chamber 12 and a charging box 14 attached to the processing chamber that allows the waste to be added to and removed from the oven.
  • Waste material to be processed is loaded into the charging box which is then attached to the oven.
  • the oven is rotated as the material therein is heated to cause it to break down.
  • the material may be heated in a zero or substantially zero % oxygen environment so that is pyrolyses therein to create gas.
  • the prior art is described as having an integral afterburner to combust the gasses being produced it would be appreciated that this afterburner may be separated from the oven and connected thereto by a conduit. It will be appreciated by the skilled person that the afterburner can either act to burn the gasses produced in the chamber to produce heat that may be usable, for example, for driving a boiler. Alternatively, the afterburner could be provided with a source of fuel and a source of oxygen to burn the fuel so that the gas in the vicinity of the afterburner that has originated from the processing chamber is heated to a high temperature so as to destroy any therein but is not in fact combusted. In this way a clean fuel gas can be produced which can be, for example, combusted in a gas turbine. Various modifications to the process parameters to achieve slightly different results depending upon the exact material being processed will be apparent to the skilled person.
  • the processing chamber has a double walled construction having an outer wall 20 and an inner wall 22 .
  • the processing chamber has an open end 24 through which material may enter the processing chamber from the charging box (see FIG. 1 ).
  • a plurality of retarder means 26 extends from an actuator 28 located outside the processing chamber, through the space 25 between the outer wall 20 and the inner wall 22 , and protrude into the processing chamber. Although only three such retarder means are shown for clarity in reality a large number of retainer means may be used. In particular an XY array of retainer means and the retainer means may be provided on more than one side of the processing chamber. As the processing chamber is rotated the retarder means 26 slow the movement of the material 29 being processed thereby increasing its exposure to heat.
  • Each retarder means comprises a plurality of inverted hook elements 30 positioned in a circular array around a common central axis.
  • the central axis forms a shaft 32 that passes through the inner wall 22 to a magnetically repelled plate 34 at the end of the shaft 32 which in turn is activated by an actuator 28 located outside the processing chamber.
  • the actuator 28 is preferably of the magnetic type such that when energised the shaft 32 of the retainer means which is at least in part made from a porous material, will be pulled down into the actuator thereby moving the retarder means from its active position 26 a to its inactive position 26 b as depicted in FIG. 3 .
  • the inner wall 22 has clearance holds that allow the shaft 32 of the retarder means to pass there through and guide the shaft loosely as it travels between its active and inactive positions.
  • the holes in the inner wall do not have to be gas tight as it is not problematic if a small amount of gas leaks through these holes.
  • the inner wall 22 has a plurality of gas inlets 36 that allow hot gasses passing between the outer wall 20 and the inner wall 22 to pass therethrough into the processing chamber so as to come into direct contact with the material therein. The passage of the hot gas in the gap between the outer wall 20 and the inner wall 22 heats the inner wall 22 so that any material to be processed that is in contact with the inner wall is heated by means of conduction by the inner wall 22 .
  • the actuator 28 may also be configured to rotate the retarder means 26 so as to agitate the material in the oven.
  • the inverted hooks of the retarder means 26 may be manufactured from any suitable material that is resistant to heat and which has the necessary resilience to allow it to deflect as it moves between its active position 26 a and its inactive position 26 b when the actuator 28 is activated the shaft of the retarder means is pulled into the actuator and the inverted hooks of the retarder means are pulled flat against the inner wall of the processing chamber.
  • the retarder means can move from its inactive position to its active position by one of two means. Either the actuator 28 can be a push pull actuator and can directly move the retarder means from its inactive position 26 b to its active position 26 a or, alternatively, the resilience of the inverted hooks of the retarder means can use their natural spring force to return to their natural position thereby moving the retarder to its active position.
  • FIGS. 4 and 5 show an alternative arrangement of retarder means wherein the shaft 38 of the retarder means does not extend through a seal in the outer wall of the processing chamber.
  • the shaft 38 terminates in a plate 40 within the space between the outer wall 20 and the inner wall 22 .
  • the actuator 28 is a strong electromagnet and the plate 40 and/or shaft 38 are ferrous. Activation of the electromagnet 28 pulls the plate 40 in the direction of arrow A thereby moving the retarder means 26 to its inactive position.
  • the electromagnet 28 is deactivated the natural resilience of the retarder means 26 moves it in the direction of arrow b into its active position.
  • the inverter hooks 30 of the retarder means may comprise hollow tubes and the retarder means 26 may have a gas inlet 42 on the shaft 38 that extends between the outer wall 20 and the inner wall 22 . Gas flowing between the two walls can therefore enter the shaft 38 , pass through the inverted hooks of the retarder means 26 and exit from the ends thereof into the processing chamber.
  • the ends of the inverted hooks 30 of the retarder means are bent up so that their end is facing away from the inner wall 22 of the processing chamber ensuring that gas can pass into the material sat on top of the retarder means and not into the inner wall 22 .
  • the retarders 26 have a hinge joint 44 that is in the processing chamber when the retarder is in its active position and which is in the space 25 between the inner wall 22 and the outer wall 20 when inactive.
  • the tips of the retarder 26 bend at its hinge 44 and the plurality of hook elements expose themselves to a grater surface area of the moving material within the chamber thereby increasing the retarding effect of the movement thereof.
  • Activation of the electromagnet 28 creates a force on the plate 40 and moves the actuator to its inactive position.
  • the hinge 44 passes through the inner wall 22 it will re-orientate the retarder 26 in its original position.
  • hinging the retarders their inverted hooks act to catch some of the material as it tumbles and this assists in retaining the material in contact with the largest surface area of the chamber walls.
  • the retarder means when the retarder means are covered with material that has been processed they may be moved between there active and inactive positions so as to agitate the material being processed.
  • the retarders can be moved between their active and inactive positions as the oven rotates. It will be appreciated that the sequencing of the retarders can be varied depending on the exact material being processed. However, the purpose remains the same, that is to maximise the exposure of the waste material to the incoming hot gasses and the sides of the processing chamber that become heated by the passage of the gasses thereover.
  • the lump of material 29 has a low surface area in contact with the walls of the chamber and there will be a large area of heated chamber wall 46 that is not in contact with the material in either position. This increases the time taken to get heat into the material and thereby increases its processing time.
  • the retarders 26 which are in their active extended position on the surface the material is moving across slow the movement, and separate the material as it moves so that it does not all move as one mass. This has two effects. Firstly the surface area/volume ratio of the material is increased and secondly a larger amount of that area is in contact with the heated walls of the treatment chamber.
  • Some materials being processed may be quite dense and their mass may be sufficient to block or partially block the flow of hot gasses into the treatment chamber from the nozzles.
  • the retarders can, in this case, be moved between their active and their inactive positions. Moving them in this manner will move the material covering the jets and enable hot gasses from the jets to better permeate into the material.
  • the retarders themselves may also have hot gas passages therethrough to disperse hot gas into the material as they move.
