Pulsed Flow Patents (Class 34/365)
  • Patent number: 9089160
    Abstract: A device for thermally treating a pourable plant product includes a receiving device configured to receive the pourable plant product and a gas supply channel configured to supply a heated gas to the receiving device. The gas supply channel is divided directly upstream of the receiving device, in a gas flow direction, into a first gas supply sub-channel and a second gas supply sub-channel which follow each other in a direction of gravity, and which are configured to supply the heated gas to the receiving device. A cross section of at least the first gas supply sub-channel is configured to be closed or reduced before the receiving device independently of the second gas supply sub-section so as to eliminate or reduce a volume of the heated gas to the receiving device via the first gas supply sub-channel.

  • Patent number: 8490292
    Abstract: The present inventions relate to pulse combustion dryer apparatus and associated methods. The pulse combustion dryer apparatus may include a combustor that defines a combustion chamber that is in fluid communication with a tailpipe passage defined by a tailpipe. An air inlet communicates air into the combustion chamber through an air inlet passage. A fluid diode disposed within the air inlet passage allows airflow into the combustion chamber through the air inlet passage, and may generally prevent backflow of heated combustion products from the combustion chamber through the air inlet passage.

  • Patent number: 6464737
    Abstract: A production method and system for granulating powdered material wherein powdered material is fluidized by applying heated pulsating vibration air, and the fluidized powdered material is suspended up and down at a regular cycle by means of heated pulsating vibration air, the aggregated material is compressed by further vibration of pulsating vibration air, whereby the aggregated powdered material is efficiently made into granulated material with high density and rather small specific volume without causing projection on the surface and without being made porous. The production system is comprised of a granulation tank for storing powdered material to be granulated, the granulation tank having a supply port for introducing heated air at the bottom thereof, a discharge port for discharging the introduced heated air at the top thereof, and a fluidization bed provided above the supply port for receiving the powdered material.

  • Patent number: 6000145
    Abstract: A method for the continuous treatment of particulate material, such as cement raw meal, in an apparatus comprising a stationary reactor (6) configured as a conical spouted bed, to which the material is fed and treated in a suspended bed by means of gas which, via a centrally arranged gas inlet (21), is injected at the bottom of the reactor (6) and flows upwards through the reactor (6), and wherefrom the material is discharged via an opening (21) at the bottom of the reactor (6).

  • Patent number: 5918569
    Abstract: An apparatus and method for processing materials in a batchwise or continuous fluidised bed, such as a drier, in which the fluidised bed is subdivided into a plurality of smaller areas, to each of which two separately controlled gas flows are provided. The first lower gas flow is provided to the bed preferably all of the time, and is sufficient at least to maintain the bed in an expanded state. The second higher gas flow is provided to each separate area of the bed in sequence by means of a rotary valve arrangement, and is high enough to induce fluidisation in the bed, but not high enough to induce significant solids loss by entrainment in the offtake gas. The higher flow sequence can be chosen to provide almost any desired sequence to the separate parts of the bed. The sequence can be chosen to induce a travelling wave within the bed which can be across or along the bed, and can be skewed relative to the sides of the bed.

  • Patent number: 5911488
    Abstract: The present invention relates to a method for preventing agglomeration while drying sticky particles in a fluid bed. The method comprises supplying sticky particles to an upper surface of a perforated conveyor and advancing said sticky particles through the fluid bed, supplying drying air flow substantially upwards through the perforated conveyor to the sticky particles on it. While drying the particles exposing them substantially, from above, to a pulsing air flow so that they are caused to move and to break up agglomerates of sticky particles. This is done while controlling drying and pulsing air flow, pulsation, and drying air temperature. The invention also relates to a fluid bed preventing agglomeration while drying sticky particles.

  • Patent number: 5638609
    Abstract: The present invention is directed to drying and heating processes and to an apparatus incorporating a pulse combustion device that can be used in a drying system or in a heating system. In general, the apparatus includes a pulse combustion device for the combustion of a fuel to produce a pulsating flow of combustion products and an acoustic pressure wave. The pulse combustion device has a combustion chamber connected to at least one resonance tube. A resonance chamber surrounds at least a portion of the pulse combustion device and includes a nozzle downstream from the resonance tube. The nozzle accelerates the combustion products flowing therethrough and creates a pulsating velocity head. In a drying system, the nozzle exits into a drying chamber where the combustion products contact a feed stream.

  • Patent number: 5579588
    Abstract: A method for metering solid present in the gas/solid stream of a fluidized-bed apparatus, in which gas and solid are present as a prehomogenized, free-flowing mixture in a fluidized bed and in which at least one outlet orifice for removal of the gas/solid stream is provided in an outflow pipe. The method provides for feeding a particulate phase and a gas phase, homogenizing the two phases in a fluidized bed, discharging the two-phase flow via a discharge pipe and injecting gas into the discharge pipe.
