  • Patent number: 4263723
    Abstract: The invention concerns the design arrangement of the cap for the inlet of fluid into the fluidization bed which is heated or cooled by the methods described in U.S. Pat. Nos. 3,897,546 and 3,908,284. The cap is formed by an inlet pipe closed at its upper end on which are formed two or more mutually separated chambers, while in this pipe a number of holes is drilled for the inlet of fluid into the chambers. Into these chambers a number of holes are drilled for the outlet of fluid from these chambers into the fluidized-bed. The vertical distance of the inlet holes from two neighboring chambers of the cap either equals or is smaller than one and one-half times the height of the heat exchanger situated in the particular fluidization bed formed between these two neighboring chambers of the same cap. The caps were used for the inlet of the combustion air into a fluidized-bed combustor, while the pressure drop of the lower part of the cap did not exceed 10% of the pressure drop of the upper part of the caps.

  • Patent number: 4223843
    Abstract: An air distribution apparatus for delivering an oxygen-carrying gas such as air to a zone of spent catalyst in a regenerator for the purpose of combusting air with the spent catalyst in order to rejuvenate the catalyst. A header support assembly is adapted for mounting in a regenerator which receives the spent catalyst. A hollow header ring is mounted onto the header support assembly and includes a plurality of openings each having a nozzle mounted therein. Air is supplied to the header support assembly and thus to the hollow header ring at a pressure sufficiently high to effect a maximum desired pressure differential between header pressure and pressure in the zone of spent catalyst to cause maximum uniform air distribution. The nozzles mounted in the openings in the header ring decrease air velocity between nozzle inlet and nozzle outlet in order to provide for maximum uniform air distribution without destruction of the catalyst.

  • Patent number: 4167245
    Abstract: Spray dispensing of a metered quantity of a preferably semi-liquid product from a filled container having a fixed wall provided with at least one and preferably a plurality of generally open and unobstructed discharge passageways. A moveable wall spaced apart from the fixed wall is impacted with a moving mass to induce a pressure pulse in the product sufficient to surge a metered quantity of product less than the entire content of the container through the generally open and unobstructed discharge passageways with sufficient velocity as to break away from the passageways and the remaining product within the container for ballistic travel generally normal the fixed wall outwardly of the container. A plurality of uniform discharge passageways and a proper match of product formulation and energy input produces a generally uniformly moving cluster of generally uniformly defined and moving particles.

  • Patent number: 4166834
    Abstract: An improved air injector for use in feed preparation in the primary reformer of a HABER processor for ammonia synthesis. In the HABER process, process gas is introduced at relatively high velocity downwardly in a process reactor through a vertical conduit. Along the axis of the conduit is an air supply pipe with a fixture which produces a plurality of downwardly and radially outwardly directed pipes attached to a plenum on the bottom of the air pipe. In this invention the number of circumferentially spaced pipes is doubled over the prior art and they are spaced circumferentially into rows directed outwardly at about a angle so as to present, more or less, a continuous plurality of streams of air which block the annular space and force the downflowing process gas to be turbulently mixed with the air and to form a pressurized mass of process gas and air, which is then forced, by the gas pressure, to flow downwardly in, more or less, a uniform manner through a volume of catalyst.

  • Patent number: 4141502
    Abstract: A pulsating water jet massage shower head comprises a shower head housing which has an interior chamber which opens outwardly. A nozzle member comprising a flat plate nozzle portion in a cylindrical fitted portion is fitted into the chamber of the housing and it is provided with a plurality of nozzle bores which extend through hollow cylindrical pin portions which extend upwardly from the interior surface of the plate portion. A cover member is arranged in the housing chamber spaced inwardly from the nozzle member and it has a segmental closing disk portion which acts to deflect water which is delivered through connecting conduits in the housing so as to cause rotation of a valve rotor positioned between the cover member and the nozzle member. The deflection and the rotation of the valve rotor produce rotating water jets through the nozzle bores.

  • Patent number: 4116383
    Abstract: Methods and apparatus for mixing fluids which pass through a plurality of fluid passageways arranged as a repeating pattern of clusters which form a geometric array are disclosed. The axes of the passageways are offset from the overall flow axis which is essentially perpendicular to the end plane of the array and each passageway is arranged in a predetermined position. The fluid flows through the passageways with a velocity having two components including a mean flow component which is parallel to the flow axis and a nonaxial component which is perpendicular to the flow axis. Although each nonaxial component for those passageways forming any given cluster acts in a direction different from the others, they interact and cooperate with each other to induce the fluid to swirl in a generally orbital fashion around the flow axis while simultaneously advancing along the flow axis downstream of the array.
