  • Patent number: 8945286
    Abstract: The invention relates to a device and method for treating a hot gas flow containing slag and to an entrained-bed gasifier system that comprises the device. The device comprises, in a housing, an inlet arranged at the top for the hot gas flow, an immersion pipe, which is arranged vertically and concentrically in the housing and into which the inlet opens, a coolant bath, into which a lower section of the immersion pipe is immersed, and at least one raw gas outlet opening for cooled raw gas that has been freed of slag. The lower section of the immersion pipe is designed as a radially expanded gas distributor bell in the coolant bath. Said gas distributor bell is formed by a substantially conical jacket surface having a cross-section that expands downward, wherein the jacket surface has a plurality of gas passage openings, which are distributed over the circumference of the gas distributor bell. The dimensions of the gas passage openings increase with the immersion depth in the coolant bath.

  • Patent number: 8430950
    Abstract: A device for removal of fine-grained or dust-like solids from a container that is to be pressurized or is pressurized, whereby the container is equipped with a double-walled discharge cone or funnel, avoids the use of porous materials, such as sintered metals or the like, while making available good conveyance properties in the transfer funnel, without restricting the grain sizes of the material, in each instance, whereby even particle-charged gas can be used for conveyance. The gas exit openings are larger than the largest particles of the solid to be removed, and the gas exit openings are provided with a pipe connector or gas feed channel that projects into the interior of the ring chamber and has at least one angle with an imaginary horizontal plane, and the gas feed channel is part of a retention device for preventing solid from trickling into the ring chamber.

  • Patent number: 7833301
    Abstract: A diffuser for a work machine having an air breathing fuel consuming internal combustion engine with an exhaust aftertreatment device periodically elevating the exhaust temperatures to a high level. The diffuser has a venturi section and the excess contaminants from an intake air pre-cleaner are directed to the throat of the venturi to aspirate and dispose of excess contaminants while cooling the exhaust flow. Additional openings in the divergent section of the diffuser assist in providing significant reductions in exhaust temperatures within a short axial envelope.

  • Patent number: 6582498
    Abstract: In a method of separating carbon dioxide from a gas mixture, a liquid solvent flows down an array of vertical wires with the gas mixture flowing over the liquid. Once on the wire, the liquid quickly breaks up into drops of varying sizes, with each size moving down the wire at a different velocity. Large, faster moving drops overtake the small, slower moving drops to form even larger drops. As the drops fall, new drops are created behind the falling drops. Consequently, drops of a large range of sizes are forming, colliding, and mixing as they travel down the wire. During this process, gas molecules that have adsorbed onto the liquid surface are mixed into the interior of the solvent, resulting in highly effective mass transfer and gas absorption. This enhanced mass transfer allows greater flexibility in the choice of solvent and in the system design.

  • Patent number: 5935283
    Abstract: A clog-resistant inlet structure for introducing a particulate solids-containing and/or solids-Forming gas stream to a gas processing system. The structure is composed of a gas-permeable wall enclosing a gas flow path, and an outer annular jacket circumscribing the gas-permeable wall to define an annular gas reservoir therebetween. The clog-resistant inlet structure is constructed, arranged, and operated so as to introduce a gas into the annular gas reservoir during the flow of the particulate solids-containing and/or solids-forming gas stream to a gas processing system through such inlet structure at a pressure sufficient to combat the deposition or formation of solids on the interior surface of the gas-permeable wall. The inlet structure may further optionally include a downstream annular section in which the wall surface bounding the gas stream is blanketed with a falling liquid film, to combat solids deposition or formation on the blanketed wall surface.
