  • Patent number: 10646843
    Abstract: In a solid waste treatment system comprising an autoclave (201) not having a particulate filter at its outlet, a method of removing particulates suspended in steam discharged from the autoclave following processing of solid waste is disclosed. The method includes discharging steam from the autoclave; routing the steam to the inlet (301) of a separation vessel (209) that further includes an outlet (303) and a baffle (302) between the inlet and the outlet; and collecting particulates (304) that drop from suspension in the steam at the bottom of the separation vessel. The baffle is configured so that steam is incident upon the baffle to reduce its flow velocity.

  • Patent number: 9993760
    Abstract: The disclosure provides a particle separator for removing aerosolized particles from exhaust emissions from a preconditioner or other apparatus. The separator comprises an enclosure with at least two baffles linearly spaced from one another therein. At least two baffles prevent the exhaust from linearly flowing directly from an inlet through the separator to an outlet. Each baffle is positioned at an angle relative to the linear flow of exhaust into the separator and a distance from an inner surface of the separator. This places a leading edge within the exhaust flow to redirect a portion of the flow, thereby promoting impact of particles on a portion of the inner surface of the separator, while also providing a surface that collects particles in the flow that impact the baffle surface. The separator and baffle surfaces can be cleaned through an access. The separator can be box- or tube-shaped or other configuration.

  • Patent number: 8376323
    Abstract: A tower/frame structure of interconnected columns and beams (which may be used in a cooling tower) and novel columns, beams, connection mechanisms and other components are provided. In one embodiment, a column and a beam are constructed of pultruded composite fiber-reinforced plastic (FRP) materials. The beam includes two sidewall extensions or flanges (each having one or more attachment apertures) at one end and which are integral with the beam for connection to the column (having one or more corresponding attachment apertures). The dimension/spacing between the inner walls of the two flanges substantially equals or is slightly larger than the outer dimension of the column. The attachment holes are aligned and a fastener is inserted through the extensions and column for attaching the column and beam. The C-shaped end of the beam substantially conforms to the cross-sectional shape and dimensions of the column.

  • Patent number: 8240640
    Abstract: [Technical Problem] A contactor is provided which is capable of making fluids of two phases contact each other under a good dispersion state and which can be easily multi-staged. [Means for Solving the Problems] The inside of a contactor 1 is divided into a plurality of cells 22, 32 by partition walls (a vertical wall 10, horizontal walls 21, 31) and the respective cells 22, 32 become countercurrent contacting spaces of an upflow fluid flowing up in the contactor 1 and a downflow fluid flowing down in the contactor 1. A downflow fluid injection hole 52 provided in the vertical wall 10 of each stage makes the downflow fluid blocked by the partition wall and residing inject into the neighboring cells 22, 32 of a lower stage side, while an upflow fluid flow-in port 51 provided in an upper side of the injection hole 2 makes an upflow fluid from the cells 22, 32 of the lower stage side flow in.

  • Patent number: 8235361
    Abstract: A structured packing for a reactor is formed from a metal sheet to promote heat and mass transfer near the wall of the reactor. The structured packing causes lateral flow of fluids flowing through the packing such that jet impingement of at least one reactor wall is promoted. The packing may be used in a cylindrical, annular or plate-type reactor, e.g., a catalytic reactor, or a heat exchanger.

  • Patent number: 8196906
    Abstract: A fluid aerator (1) comprising a fluid vessel (2) and a pipe (4) extending from the interior of the fluid vessel (2) to the exterior. The pipe (4) has inlet means for permitting liquid to flow into the pipe (4) from the vessel (2) and is closed at its lowermost end but has one or more outlet holes (8) arranged in the wall of the pipe where the fluid exists from the pipe (4). The pipe (4) is movable relative to the vessel (2) between a first position in which the outlet holes (8) are distant from the vessel and a second position in which the outlet holes (8) are closer to the vessel. By means of the movable fluid supply pipe (4) the same fluid aerator can be used both in relation to delivering aerated fluid into a large bottle and to delivering smaller amounts of aerated fluid to a smaller container, such as a wine glass.

  • Publication number: 20110049733
    Abstract: A water cooling tower having an improved water collection system. The cooling tower has an outer shell, legs, and one or more layers of fill material, through which the water to be cooled moves vertically downward. The water is distributed across the upper surface of the fill material by piping and nozzles. A fan underlying the fill material moves air vertically upward through the fill material. The water collection system, which is positioned below the fill material, has upper and lower troughs which receive water flowing vertically downward through the fill material. Preferably, the lower troughs are positioned beneath the spaces between upper troughs, to catch water falling between the upper troughs. A number of hinged baffles close off the spaces between lower troughs, but rotate upward in response to upward air flow and open the spaces between the lower troughs.
