Definitions
- the present invention is concerned with a method of producing refined cellulose fibres from household, commercial and industrial wastes and, in particular, the production of dried fibres suitable for further processing into, for example, fuel or wood replacement items.
- Household, commercial and industrial wastes are mainly disposed of in landfill sites, are partially disposed of by incineration or partially recovered for recycling.
- An alternative method is the thermal treatment of these wastes in an autoclave type process; such processes are known in the field of waste treatment.
- This steam treatment or autoclave system produces, as its main by- product, a fibre product typically containing moisture in the range 35% to 60% by weight and other unwanted materials such as glass, metals and aggregates described further as grit particles.
- the fibre by-product is used as a low value soil enhancer or can be further processed to manufacture a compost. However, it is typically dumped to land-fill sites.
- a method of treating fibres produced by the thermal treatment of waste materials with pressurised steam which method includes, drying the fibres such that the moisture content of the fibre is in the range of from about 4 to about 15% by weight of the fibre,- and substantially removing debris (such as grit and/or plastics material) from the treated fibre.
- the method further includes reducing the size of the refined treated fibre to length typically less than about 35mm (preferably less than 25mm.
- the refined treated fibre is both clean and sterilised.
- the length of the fibre is typically adjusted to suit the requirements of products manufactured from the treated refined cellulose material.
- the resultant dry fibrous material produced by the steam treatment of the waste typically comprises substantially cellulose material derived from mixed vegetable matter.
- the fibres produced by the treatment of waste materials with pressurised steam typically have a moisture content in the range 25-50% calculated by weight ratio, such fibres prior to treatment according to the present invention are difficult to separate from inert and plastics material which contaminate them.
- Wood replacement products may include cardboard, paper, insulation board, hardboard, or the like.
- the communition of household, commercial and industrial packaging waste is achieved by applying steam to the unsorted waste in a rotating pressure vessel.
- the paper, cardboard and petruscibles are converted to cellulose fibres.
- the thermoplastics are partially melted during this process and become ball shaped as a consequence of vessel rotation, whilst the thermoset plastics together with metals, aggregates, glass and other inert materials are cleaned, sterilised and physically remain unchanged.
- the cellulose fibres remain as a residue upon the removal of all other elements, listed previously, are separated.
- Pressurised steam is advantageous over the prior art methods as it substantially doesn't slip, doesn't break, never turns it's edge, doesn't wear and conditions the derived fibres just as effectively.
- the combination of steam pressure and temperature, as applied to the waste, also renders potentially harmful bacteria and pathogens harmless in contrast to many prior art methods which do no .
- the pressurised steam has a pressure in the range 3Bar to 8Bar, such as about 5Bar.
- the temperature of the pressurised steam is preferably in the range about 100°C to 250°C, further preferably 130°C to 200°C, such as about 160°C.
- the fibres produced by the thermal treatment of waste materials may include undesirable waste material such as textiles, wood, aggregate, glass, metal and plastics during a screening process.
- a preferred screening process includes the use of a rotary trommel-type screen, which separates through apertures of preferably 4-20mm (such as 6 -12mm) .
- the fibres that pass through the screen as the undersize product may still contain inert and/or plastic particles.
- the inert and/or plastic particles are substantially removed.
- the moisture content of the fibre is reduced to moisture content in the range 4 to 15% by use of a drying apparatus.
- the drying apparatus may also be used to substantially remove debris from the fibre and/or reduce the particle size of the debris. This process is typically a combination of both mechanical and thermal energy.
- the fibres in the drying apparatus achieve a temperature in the range 120°C to 350°C, preferably about 150°C to 300°C, thereby evaporating the moisture present.
- the drying apparatus preferably includes a removal device for inert material and/or plastics removal .
- the removal device is typically a rotating shaft fitted with a series of strategically placed paddles, diametrically opposing and along the length of the shaft .
- the paddles when rotated at a predetermined peripheral speed advantageously induces a forward movement of the fibres and a centrifugal force to act on the heavier inert and plastic particles, which are directed to the sidewall of the drying apparatus for collection and disposal
- moisture removed during the production of the refined fibre is passed, typically in vapour form, through an oxidizing device to remove potential odour pollutants.
- the density of fibres processed according to the present invention are typically in the range of about 50 to 120kg/m 3 .
- the pre-treated fibres have a density typically in the range of about 250 to 500kg/m 3 .
- the refined cellulose material is typically graded according to its density.
- the grading is typically carried out using an air current separator.
- the refined cellulose material can be water washed through sieves, which is particularly desirable for use in the manufacture of cardboard and/or paper.
- the pre-treated fibres are typically not suitable for the use as fuel or the manufacture of wood replacement products.
- the pre-treated fibres contain too much moisture and grit particles to use as a gasifier fuel or to agglomerate as solid fuel or to manufacture wood replacement products.
- the reduction of moisture to a range of 4-15% by weight and the removal of grit particles advantageously enables the use of the fibres as a gasified fuel or agglomeration as solid fuel or the manufacture of wood replacement products.
- a method of producing a refined cellulose material which method includes: a) providing a fibre material obtained from the treatment of waste materials with pressurised steam; b) drying the fibre material such that the moisture content is in the range from about 4% to about 15% by weight of the fibre; and c) substantially removing undesirable debris (such as plastics material and/or grit) from the product obtained in b) , so as to obtain the refined cellulose material .
- the fibre material is graded and/or sorted prior to step b) .
- inert and/or plastics particulate material are substantially removed. Such removal may be by use of a screening vessel, for example a rotary trommel - type screen.
- the refined material is in the finely divided form, typically having a length of less than about 35mm, preferably less than about 30mm, further preferably less than 20mm.
- the refined cellulose fibres according to the present invention can be used in the manufacture of gasified fuel, agglomerated solid fuel, in the manufacture of replacement wood products, insulation materials and/or attenuation material.
- the refined cellulose material according to the present invention can be blended with a carbonaceous material (such as coal, coke fines or the like) to produce a fuel .
- a carbonaceous material such as coal, coke fines or the like
- the carbonaceous material can be present in the blend in an amount in the range 1 to 99%, preferably 5 to 95%, by weight of the blend of carbonaceous material and refined cellulose material.
- the blend of carbonaceous material and refined cellulose material is typically agglomerated using standard agglomeration techniques.
- the blend is typically mixed with a binder prior to agglomeration.
- Typical binders include lignm and urea, molasses and lime, resins, polymers (especially polyvmyl acetate) ,- however, it is envisaged that any binder known in the art of agglomeration may be used.
- the refined cellulose material according to the first aspect of the present invention may also be used in the manufacture of wood replacement products, such as, for example, multi density fibreboard products.
- the bulk substance consisting of household, commercial and industrial packaging waste is continuously placed on conveyor 1.
- the bulk substance has been subjected to inspection upon receipt and only coarse materials unsuitable to the process are removed. Examples of coarse materials are rolls of carpet, wooden pallets, tree trunks, car engines and the like.
- the process vessel 2 When a sufficient batch of the bulk substance is filled into the vessel, conveyor 1 is stopped, the filing operation ceases and the sealed vessel door is closed.
- Pressurised steam is applied to vessel 2 until an internal steam pressure (typically 5 Bar) is achieved.
- the pressure vessel 2 is rotated at a speed in the range 5 to 10 revolutions per minute for a period of 25 to 45 minutes.
- the rotational speed of the vessel and the duration of this period is determined by the quality requirement of the resulting processed cellulose fibre product.
- the 'cooking cycle' On completion of the applied steam pressure cycle (referred to as the 'cooking cycle'), the steam flow is stopped and the steam pressure is released from vessel 2 until normal ambient conditions prevail internal to the vessel . Only when these conditions are achieved can the vessel sealed door be opened.
- the method for discharging the processed bulk substance is by reversal of the rotational direction of the vessel compared to the direction of rotation used during the filing operation.
- the processed bulk substance is transferred along conveyors 3 and 4, in the direction of the arrows, and deposited into the rotary trommel screen 5.
- the rotary trommel screen 5 serves to separate the bulk substance into two fractions, namely the oversized, typically above 12mm, and the undersized, which is smaller than 12mm.
- the oversized materials are delivered via conveyor 6 to the stockpile 7 for additional sorting.
- the undersized material is then subjected to the method of the present invention.
- the undersized material is delivered via rotary screen 5 to conveyor 8, which contains the cellulose fibres with inert and plastic particulate materials which are considered to be contaminants.
- the undersized materials are delivered into the drier 9, which is specifically designed to remove the inert and plastic particulate material of the cellulose fibres.
- the drier performs two functions in drying the substances and removal of the inert and plastics particulate material .
- the fibres whilst passing through the drier are cleaned of inert and plastics particulate material by coming into contact with a rotating shaft fitted with paddles.
- the paddles are attached to the shaft in a predetermined pattern such that centrifugal force created by the rotating shaft acts on all particles in contact with the particles.
- the fibres which are low in density remain in the airflow and are deposited at the outlet of the drier subsequently to be delivered on conveyor 12.
- the denser and inert plastics particulate material are thrown by centrifugal force into the inner wall of the drier tube and collected in the base of the tube.
- Situated at the base of the drier tube are a series of power operated doors which allow the passage of the inert and plastics particulate material but prevent the ingress of air. The ingress of additional air into the drying chamber would interfere with the steady air flow conditions necessary for the efficient segregation and transfer of fibres through the drier.
- the residual inert and plastics particulate material are deposited from the dyer onto conveyor 10 for transfer to stock pile 11 for disposal.
- the conditioned cellulose fibres are transported along conveyor 10 and deposited on stock pile 13.
- the cellulose fibres in stock pile 13 are clean and sterile after the completion of the aforementioned production process.
- the preferred embodiment described above is of only one process cycle. Repeated batch cycles carried through a multiple of pressure vessels will determine the throughput of the process plant .
