  • Patent number: 9944549
    Abstract: A dewatering device comprised of a multiple drum and conveyor system, the device has two or more roller drums about which an endless supporting belt is located to provide a movable supporting area between the rollers. The belt supports a filter medium which also passes about the rollers. The belt has a number of apertures allowing passage of liquid through the filter medium and below the belt. The belt is also formed with a series of transverse troughs which help guide the mixture toward the apertures situated in the troughs. A vacuum chamber (i.e. a “suction box”) is placed under the belt between the rollers and forms a pressure gradient through the cloth and belt to suck the liquid from the mixture via the cloth and apertures.

  • Publication number: 20130292314
    Abstract: A pressure filtration system for cleaning residual quenching water of a gasifying device that gasifies carbon-containing fuels under elevated pressure is provided. The soot water from the quencher is passed to a filter system, which has pressure filter chambers operating alternately in filtering mode under gasifying pressure or in cleaning mode. The filtrate from these chambers is passed to a quenching water reservoir, from which the quencher is fed with quenching water. Only small temperature and pressure losses with respect to the residual quenching water leaving, and only a small additional amount of energy has to be expended to overcome the remaining pressure difference to bring the filtrate that is to be returned back to the gasifying pressure. The residual quenching water is cleaned substantially under gasifying pressure in a pressure filter, avoids flash evaporation of the residual quenching water into the vacuum area, with vapour cooling and a subsequent increase in pressure and reheating.

    Abstract: A system for collecting matter provides a low energy, low cost and nearly zero pollutant process for extracting suspended matter in a medium. The system collects the matter on a material which is deployed into the medium, and the matter is extracted off the material. If an oil spill occurs in a body of water, then the material can rapidly remove the oil from the water in high concentrations. If oil or bitumen is mixed with water due to tar sands processing, then the material can extract the oil or the water depending on a balance of oleophilic or hydrophilic properties of the material. The extracted matter and the medium can proceed to further processing such as water purification and/or petroleum refining. This invention collects matter in an economically and environmentally viable manner.

  • Patent number: 8518259
    Abstract: An apparatus for de-aering, oxygenating and controlling a temperature of blood in an extracorporeal blood circuit. The apparatus includes a housing, a manifold body, a heat exchanger, and an oxygenator. A blood inlet tangentially directs blood into a first chamber of the housing. The manifold body is disposed in a second chamber, and includes a core and a plurality of vanes that define channels. The heat exchanger is arranged around the manifold body, and the oxygenator around the heat exchanger. The channels are open to the heat exchanger. An established blood flow path includes rotational flow within the first chamber to separate air from the blood, generally longitudinal flow from the first chamber and along the channels, and generally radial flow through the heat exchanger and the oxygenator. With this construction, gross air removal occurs prior to the blood passing through the heat exchanger and oxygenator.

  • Patent number: 8496806
    Abstract: Provided is a dehydrator that requires no excessively large apparatus structure and achieves cost-saving while maintaining suction efficiency at a desired level by use of suction means. A dehydrator 100 for separating water from a target liquid 13 includes at least two water separation membrane units 1a and 1b which are provided in series in a flow direction of the target liquid 13. The water separation membrane unit 1a on an upstream side out of the water separation membrane units 1a and 1b is connected to suction means 7 for sucking a gas phase containing water through one condenser 4, and the one condenser 4 condenses water in the gas phase and thereby separates the water. The gas phase sucked by the suction means 7 from the one condenser 4 is transferred to at least one downstream condenser 8 provided downstream of the one condenser 4, and the downstream condenser 8 condenses water in the gas phase and thereby separates the water.

  • Patent number: 8490682
    Abstract: A suction filter providing a heat transfer pathway therein is provided. The suction filter includes a support structure, an inlet connected to the support structure, a filter element connected to the support structure, and a thermally conductive element that communicates with an interior portion of the suction filter. The filter element is configured to filter a fluid as it passes through the filter element into an interior portion of the suction filter. Also, the thermally conductive element extends from the interior portion of the suction filter to an exterior portion of the suction filter. The thermally conductive element is configured to transfer heat obtained external the suction filter to the interior portion of the suction filter in order to provide heat to the fluid in the interior portion of the suction filter.
