Publication number: 20140076159Abstract: An inertial inlet particle separator system for a vehicle engine is provided. A separator assembly and collector assembly are coupled to the scavenge flow path and configured to receive the scavenge air. The collector inlet has a throat defining a cumulative throat area at each position along the throat length from the first throat end to the second throat end. The collector body defines a cross-sectional area associated with each position along the throat length between the first throat end and the second throat end. The collector outlet is coupled to the collector body such that scavenge air flows into the collector inlet, through the collector body, and out through the collector outlet. At a first position between the first throat end and the second throat end, the respective cross-sectional area of the collector body is greater than or equal to the respective cumulative throat area.Type: ApplicationFiled: September 17, 2012Publication date: March 20, 2014Applicant: HONEYWELL INTERNATIONAL INC.Inventors: Zedic Daniel Judd, Yogendra Yogi Sheoran, Jennifer Ann Reich, Todd A.

Patent number: 8663352Abstract: A system for purifying as includes at least one housing (2) having a first chamber (6) into which the gas to be purified can flow, and a second chamber (10) forming a filter chamber, out of which the purified gas exits and with a filter device through which the gas can flow. The filter device has filter media (54) for separating out solid particles and for dehumidifying the gas for precipitating coalesced fluid. The first chamber (6) has a cyclone (60) for pre-dehumidifying the gas, from which dirt particles and fluids can be discharged into a third chamber (14) of the housing (2). The housing (2) is composed of an upper housing part (8) with the second chamber (10) forming the filter chamber, a middle housing part (4) with a first chamber (6) having the cyclone (60), and a lower housing part (12) forming the third chamber (14), that can be clamped together by at least one tensioning bolt (32), forming a closed pressure vessel.Type: GrantFiled: May 4, 2010Date of Patent: March 4, 2014Assignee: Hydac Process Technology GmbHInventors: Jörg Sczesny, Manfred Deutschmeyer, Bernhard Schlichter

Patent number: 8657933Abstract: A powder cyclone separator for use in a powder coating system is formed in two separate and separable sections. An upper section is mounted on a first frame and remains stationary. A lower section is mounted on a second frame that is movable laterally away from the first frame so that an operator has more ready access to clean interior surfaces of the upper section. Optionally, actuators may be provided to raise and lower the cyclone lower section with respect to the cyclone upper section. Optional alignment means are presented for aligning the cyclone upper and lower sections. A control mechanism may be mounted on the second frame which includes a switch that is operable to raise and lower the lower section with respect to the upper section. This design allows an operator to see and verify that virtually all internal surfaces of the cyclone have been cleaned.Type: GrantFiled: October 31, 2011Date of Patent: February 25, 2014Assignee: Nordson CorporationInventors: Larry C. Jancik, William C. Coomer, III, Greg Dawson, Michael Thomas, Francis Patrick Mohar

Patent number: 8657928Abstract: A versatile compact air precleaner, air cleaning method and disposable air filter cartridge for air precleaner for separating heavier-than-air particulate debris from debris laden air to provide a clean airflow, wherein a flow path for air passing through a separator chamber of the air precleaner is retroflexed en route to the outlet. A plurality of independently rotatably adjustable housing sections of a housing provide utility with multiple clean air outlet configurations, freedom of direction of ejection of particulate debris from the ejector ports, different inlet configurations, mounting of the precleaner from different sides, accommodation of different sizes of filters, and different clean airflow rate capabilities. A separator chamber end section including the ejector ports is connected to the filter as a removable, disposable air filter cartridge to obviate ejector port clogging with change of filters.Type: GrantFiled: September 28, 2011Date of Patent: February 25, 2014Assignee: The Sy-Klone CompanyInventors: James G. Moredock, Eric L. Ehrenberg

Patent number: 8657935Abstract: A method and system for expanding, separating, and compressing a multi-phase fluid. An expander receives and expands the multi-phase fluid to generate a lower-pressure fluid which can more efficiently be separated in a separator. Expanding the fluid also drives a main shaft adapted to drive at least the separator and a compressor coupled thereto. The separator receives the lower-pressure fluid, separates any higher-density components from the lower-density components disposed therein, and provides a substantially dry gas to the compressor to be re-compressed and discharged from the system.Type: GrantFiled: May 19, 2011Date of Patent: February 25, 2014Assignee: Dresser-Rand CompanyInventors: Pascal Lardy, H.

Patent number: 8657932Abstract: A separator comprises a separation chamber (1) with at least one inlet (11a) in its upper part, a solids outlet (12) in its lower part and two outlet pipes (2 and 3) for fractions of gas. Also described is a method which the separator uses, with the fractions of gas being sucked out in two separation zones generated inside the chamber, one with reverse flow and the other with unidirectional flow.Type: GrantFiled: June 25, 2009Date of Patent: February 25, 2014Assignee: Petroleo Brasileiro S.A.—PetrobrasInventors: Wilson Kenzo Huziwara, Celson Murilo Dos Santos, Rogério Michelan, Emanuel Freire Sandes

Patent number: 8657934Abstract: A cyclone for separating sticky particles from gas streams includes an inlet duct having an end in a direction of a particle outlet. The end has a flow cross-section including a triangular expansion that is formed laterally by a vertical of a cylindrical outer wall of the cyclone and by art outer boundary of the cyclone. An outer angle of inclination between the vertical and the outer boundary, proceeding from the end of the inlet duct, is reduced from 30° to 0° in a flow direction of gas streams. An immersion tube is disposed eccentrically in a direction of the inlet duct.Type: GrantFiled: August 4, 2010Date of Patent: February 25, 2014Assignee: Outotec OyjInventors: Michael Missalla, Mithat Schmitz

Patent number: 8657896Abstract: A separator is disclosed. The separator includes a gas/liquid separator vessel, an enclosure, a coalescer and a demister. The gas/liquid separator vessel has a first end, a second end, a first inlet, a first outlet, and a first separation chamber. The first inlet can be adjacent to the first end. The enclosure is positioned within the first separation chamber of the liquid separator vessel. The enclosure has a second inlet, a second outlet, a drain positioned therebetween, and a second separation chamber. The second inlet can be directed towards the first end of the gas/liquid separator vessel. The second separation chamber defines a flow path for a gas stream in which the flow path passes sequentially through the second inlet, second separation chamber and the second outlet. The coalescer is positioned in the second separation chamber to intercept the flow path of the gas stream.Type: GrantFiled: July 31, 2011Date of Patent: February 25, 2014Assignee: Schlumberger Technology CorporationInventors: Laurence Gouy, Francis Allouche
