    Abstract: A centrifugal spark arrestor having a main body portion with a first end and a second end spaced from one another. The main body has an interior wall defining a flow path for the flow of air through the main body and a longitudinal axis. An inlet is positioned at the first end and extends generally perpendicular to the longitudinal axis. The inlet is in operative communication with the flow path. An outlet is positioned at the second end; the outlet is in operative communication with the flow path. At least one baffle is positioned within the main body portion between the first and second ends, partially extending into the flow path. Air is pulled into the inlet and forced initially in a direction perpendicular to the longitudinal axis and against the interior wall. The air is forced through the main body portion to the outlet in a centrifugal flow path. The baffle is engaged by the air flowing through the main body portion with any particles entrained within the air impinging upon the baffle.

  • Patent number: 7806955
    Abstract: A gas-liquid separation system and a method thereof are disclosed. The said system comprises a gas-liquid separation conduit and a drain pipe. The drain pipe is curled and one side of the drain pipe connects to the gas-liquid separation conduit and the other side connects to a sewage pipe. According to the U-Tube principle, the gas and the liquid which both are exhausted by a machinery can be separated in the said system and therefore the said system can prevent related processes causing exhaust piping jam.

  • Publication number: 20100186592
    Abstract: The present invention provides an air cleaner suitable for forced air open-ventilation systems used to cool electrical machines. The air cleaner comprises an air chamber with a first end where air is drawn in from the surroundings, via an inlet, by the open-ventilation system and a second end, opposite the first end, where air is drawn out of the air chamber, via a first outlet, by the open-ventilation system. A rotating means is contained within the air chamber and may be driven to rotate about an axis that extends between the first end and the second end of the chamber. When driven to rotate, the rotating means applies a centrifugal force to any particles contained in the air entering the air chamber and throws them radially outwards from the central axis. These particles are then drawn out of the air chamber, via at least one second outlet formed adjacent to a radially outer edge of the rotating means, by a high-velocity outlet stream of the open-ventilation system.

  • Publication number: 20080264017
    Abstract: A multi cyclone dust-separating apparatus is disclosed that includes a cyclone unit having a first cyclone, a plurality of second cyclones, and a dust collecting unit. The first cyclone is disposed so that a longitudinal axis thereof is substantially vertically arranged. The first cyclone separates relatively large dust or dirt from air drawn in through a first air inflow part. Each of the second cyclones is disposed so that longitudinal axes thereof are substantially vertically arranged. Each of the second cyclones has a second air inflow part to communicate with the first cyclone and an air discharging part to discharge the air. The second cyclones separate relatively minute dust or dirt from the air drawn in through the second air inflow part. The dust collecting unit is disposed below the cyclone unit to collect and store the dust or dirt separated from the air by the cyclone unit.

    Abstract: An inertial separator includes a main duct having a first half (H1) with high aspect ratio and positive curvature and a latter half (H2) with larger average curvature and an outside wall section removed; a boundary layer suction part (H3) formed on the side of the outside wall of the latter half (H2) with the section removed; a curved duct (H4c) of a final collection part succeeding the boundary layer suction part (H3), having a larger mean curvature and a smaller radial channel width than the latter half (H2) of the main duct, with an outside wall section removed; and a collection chamber part formed on a side of the outside wall of the curved duct (H4c) with the section removed. A hybrid air cleaner combines the inertial separator with an air filter, removably having an allergen suction device sucking allergen from hair, bedding and so on, and a separated blowing mouth whereby the suspended allergen may be transported away during a patient's sleep.

  • Publication number: 20080006250
    Abstract: A separator system has a plurality of separator stages (11, 12, 13) and operates to remove particulates from air, particularly in the inlet to an engine. Each stage includes a plurality of side-by-side inertial separators (26) through which the air flows and by which particulates are removed. Each stage (11, 12, 13) produces a pressure drop and the additional total pressure drop produced by each stage after the first is less than the additional total pressure drop produced by the preceding stage in an upstream direction. This allows particulates to be removed by the separator stages (11, 12, 13) alone without the use, in normal operation, of a barrier filter (14).

  • Patent number: 7141095
    Abstract: A precursor delivery system includes a flow path from a precursor container to a reaction space of a thin film deposition system, such as an atomic layer deposition (ALD) reactor. A staging volume is preferably established between the precursor container and the reaction space for receiving at least one dose of the precursor material from the precursor container, from which a series of pulses is released toward the reaction space. The precursor material is typically vaporized after loading it in the precursor container by heating or reducing the pressure inside the precursor container. A vacuum line is preferably coupled to the precursor container and bypasses the reaction space for reducing pressure inside the precursor container without drawing particles into the reaction space. A high conductivity particle filter having inertial traps may be included, preferably between the precursor container and a staging volume, for filtering particles from the precursor material.

  • Patent number: 6981995
    Abstract: A separator device for separating heavier small particles, solids and liquids, in suspension in a fluid that are forced through a wound conduit member with a plurality of through openings on the outermost wall portion. The fluid is forced by a pressure differential between the inlet and the outlet. That causes said fluid to achieve a predetermined speed inside the conduit member. A housing covering the conduit member collects and/or contains the heavier matter that exits the through openings by the effect of centrifugal forces acting thereon. The centrifugal force generated will be proportional to the speed square and inversely proportional to the radius of curvature. Inwardly extending walls trap or force small particles outwardly through the through openings. Also, outwardly extending walls prevent the small particles and/or water in suspension from re-entering the conduit member.
