  • Patent number: 6213307
    Abstract: A first stage chamber has upwardly diverging walls so that an upward airstream has different air velocities at different heights in the chamber. When particles such as seeds are fed homogeneously along the chamber top length, they reach equilibrium at different heights depending on their weights and volatilities. The particles suspended and classified at different heights are conveyed by a horizontal airstream in parallel horizontal channels toward a chamber side wall, where they are removed by suction. Ribbed sections adjacent to the channels divide the chamber into deviating cascaded pathways, where the upward air velocity is homogenized and an opposite horizontal airstream conveys falling particles toward the side wall opposite to that on which the particles are removed, to thereby homogenize the spread of particles in the chamber. Light trash is removed through a convergent top section toward a cyclone. Heavy particles not suspended in the chamber are collected and removed at the chamber bottom.

    Abstract: Equipment and method for treating solid waste in which a non-oxidizing atmosphere is provided through which the shredded solid waste falls freely, unsupported and non-contacted, to prevent fusion of the plastics with each other, with other materials in the solid waste, or with the walls or components in the treating equipment. The unique atmosphere also allows a high treatment temperature to accelerate the debonding of fibrous combustible matter and fusion of the plastics into dense particles for substantially complete separation and recovery of plastics from the lighter fibrous but non-fusible combustible matter through gas classification during the free fall. This same atmosphere also produces a clean, unoxidized, homogeneous, storageable and highly combustible fuel derived from the fibrous combustible matter.

  • Patent number: 4253940
    Abstract: Waste materials of varying density are passed through a hammer mill for size reduction after which they are moved along a gravity path within a stream of hot inert gas. The stream of materials is intercepted by a transversely moving mass of heated inert gas that separates the lighter materials from the heavier ones. A manifold receives the lighter materials while the heavier items are picked up at a lower position by a sealed screw conveyor. An adjustably located table and damper plate enable varying the weight-cut.

  • Patent number: 4235707
    Abstract: Solid Municipal Waste is loaded, or loaded and compacted, into a pressure vessel which has means for very fast opening for discharging the contents. The pressure vessel is pressurized, with steam, or a compressed gas such as compressed air. The pressure vessel can be fitted with a breech and a quick release muzzle cover and at the discharge end (muzzle) thereof is fitted with an orifice whose purpose is to promote a powerful turbulence and shock wave, through which the exiting solid material must pass to maintain pressure within the vessel during discharge, and to control the rate of discharge. The disruptive forces produced at the orifice, which can be either a sub-sonic, sonic, or supersonic flow orifice, are a function of the strength of the shock wave or the turbulence. The discharged material is then gravity separated in the wet or dry conditions and the separated materials are then employed in additional processes, or employed as landfill depending on its chemical and physical properties.

  • Patent number: 4137155
    Abstract: A method and apparatus for pneumatically sorting products heterogeneous in nature, form and dimensions, in which the products, while freely falling are deviated by means of a transverse gaseous flux, the height of fall being adjusted before deviation of the products and before production of a second gaseous flux, characterized in that the deviations imparted to the products while freely falling are produced by compressed gases, and their trajectories are determined by the directing of the expansion of the bases between the ejection zone and the atmosphere by means of large panels formed with multiple openings.

  • Patent number: 4007744
    Abstract: The threshed material leaving the threshing cylinder of a grain harvester or combine is accelerated into a transverse air stream by a pair of rolls. The rolls are disposed on parallel axes and are rotated at a relatively high speed in opposite directions whereby their confronting peripheries engage and accelerate the threshed material to a velocity substantially in excess of the speed at which such material would fall by gravity. A wide band of relatively high speed air is directed transversely through the accelerated material to provide a precleaning of straw and chaff from the material normally passing to the grain separation or cleaning shoe section of the combine. The grain in the accelerated material continues in a relatively straight line trajectory and the straw and chaff are separated from the grain by the transverse air stream.

  • Patent number: 4005994
    Abstract: Solid waste is fed to a confined zone under pressure and contacted with hydrogen containing gas. Partial conversion of the solid waste to methane occurs and the methane containing gas mixture is removed from the confined zone; it is subsequently purified and methanated so as to be a replacement for natural gas. The remainder of the solid waste is discharged from the confined zone as a carbon containing char which is delivered to a separate reaction zone where it is contacted with steam and oxygen under pressure to convert it to synthesis gas (a mixture of hydrogen, water vapor, carbon monoxide and carbon dioxide). The synthesis gas is drawn from the reaction chamber and serves as the hydrogen feed gas into the confined zone. Between the two zones, metal and glass are separated from the char by virtue of their much higher density than the carbonaceous char by entrainment of the char in a jet of steam.

  • Patent number: 3933626
    Abstract: A classifier for particulate material of the type wherein a stream of the particles to be classified is introduced into a moving stream of air, classification being achieved by the varying degree of entrainment of the particles in the air stream due to their difference in size. The classifier employs a closed housing having a plurality of outlets, each for a different size of particle, and an inlet located thereabove. An air impeller drives a current of air across the particle outlets. The housing is closed so that the air defining the stream is continuously recirculated. At a point in the air stream downstream of the outlets there is provided an enlarged chamber through which the air flows at an extremely low velocity to preclude particles from being entrained in the air to be carried back to the air impeller.
