Patent number: 7270690Abstract: The separator has a vane assembly made up of a number of corrugated vanes that provide serpentine paths for the gas stream therethrough. As the gas stream flows through the serpentine paths, it changes direction and liquid in the gas stream impacts the surfaces of the vanes. The upstream section of the vane assembly has roughened surfaces to decrease the surface tension of the liquid, thereby causing the liquid to coalesce. The downstream section of the vane assembly has smooth surfaces so as to increase the surface tension of the liquid. The vane assembly is followed by filters, which capture the liquid that passes through the vane assembly. The vane assembly coalesces the liquid to enable the filters to operate more effectively.Type: GrantFiled: July 14, 2004Date of Patent: September 18, 2007Assignee: Harbison-Fischer, Inc.Inventor: Allen W.

Patent number: 6770121Abstract: The separator has a vane assembly made up of a number of corrugated vanes that are oriented with respect to each other so as to provide serpentine paths for the gas stream therethrough. As the gas stream flows through the serpentine paths, it changes direction and liquid in the gas stream impacts the surfaces of the vanes.

The second edges of the sheets define an air outlet portion in the body wherein the second edges of the alternate sheets define spaces between the wider adjacent sheets at said outlet portion.Type: GrantFiled: May 25, 1993Date of Patent: May 17, 1994Assignee: Munters CorporationInventor: George A.

Patent number: 5271753Abstract: A liquid-vapor separating drum has a screen dryer mounted in the upper portion between the primary separators and the vapor outlet. The screen dryer is constructed and mounted in such a way that only minimal access is required in the space above the screen dryer whereby the space can be minimized. A central pair of dryer rows is installed first when there is easy access. The two outside rows are then merely clipped in place which does not require any access. The bottoms of the rows are joined by drain panels which form a flow barrier and which serve to collect the liquid extracted by the screens. Hanging rods are used to support these drain panels and thereby indirectly support the bottoms of the rows. Vortex breakers in drain apertures of the drain panels improve the drainage rate.Type: GrantFiled: December 29, 1992Date of Patent: December 21, 1993Assignee: Combustion Engineering, Inc.Inventors: H. Rodolfo Akel, Bard C. Teigen, Gary W. Gralton, Peter Acimovic

Patent number: 5269823Abstract: A mist eliminator for eliminating droplets from a liquid-laden gaseous flow, comprising wave-shaped profiles each including an entrant part configured as a half-wave of small amplitude and wavelength, a central part configured as a principal wave of large amplitude and wavelength, and an exit part of small amplitude and wavelength, the profiles including flow passages with reversing portions where the gaseous flow is alternately accelerated and decelerated, respectively, characterized in that the wave shape of the profiles is modified as compared to a sine-wave such that the turning points of each profile at least on the eliminating surfaces of the central part are shifted in downstream direction.Type: GrantFiled: July 21, 1992Date of Patent: December 14, 1993Inventor: Dieter Wurz

Patent number: 5268011Abstract: A mist eliminator comprising baffles (2) having capture pockets (12, 16) for droplets to be eliminated from a solids-laden and/or liquid-laden gaseous flow, the mist eliminator being distinguished by the feature that each baffle (2) comprises at least two capture pockets (12, 16) which are disposed and configured in such a way that their orthogonal projection to the entrance plane (E) substantially spans the field of flow.Type: GrantFiled: June 5, 1992Date of Patent: December 7, 1993Inventor: Dieter Wurz

Patent number: 5230725Abstract: A mist eliminator for removing liquid droplets from a gas stream includes a first layer of a plurality of mutually parallel spaced partitions defining respective flow channels between the partitions. The partitions are curved to define the flow channels as circuitous paths of travel for gas. The partitions have free edge portions which define exit ports for the channels. A second layer of a plurality of mutually spaced partitions defining respective flow channels therebetween is located downstream of the first layer in the direction of air flow. The partitions of the second layer have inlet edges located in alignment with the exit ports of the first layer which are offset from the free edge portions of the partitions in the first layer. The inlet edges of the second layer are aligned with the direction of gas flow out of the exit ports of the first layer and the partitions of the second layer have main body portions extending at an angle to those inlet edges.Type: GrantFiled: December 11, 1992Date of Patent: July 27, 1993Assignee: Munters CorporationInventor: James M. Chowaniec

Patent number: 5203894Abstract: A mist eliminator pack is disclosed which is formed of a plurality of non-planar mist eliminator sheets having first and second opposed and generally parallel edges with integrally formed offset tabs in at least the first edge of the sheets. The pads are dimensioned and positioned to engage an adjacent sheet on one side of their associated sheets, with the tabs being secured to the adjacent sheets by an adhesive, or the like, thereby to define an integral pack of evenly spaced sheets having uniform flow paths between the sheets.Type: GrantFiled: April 3, 1992Date of Patent: April 20, 1993Assignee: Munters CorporationInventor: James M. Chowaniec

Patent number: 5178654Abstract: A wet scrubber system for removing dust such as coal dust from the air. The system includes an impingement board and demister. The impingement board comprises a frame with flat strips of metal or plastic attached thereto. The strips are spaced apart to permit passage of an airstream. The demister comprises a first and second row of generally V-shaped members separated by an expanded metal screen. The V-shaped members are offset, spaced apart and tack welded, at their base, to the screen to form a generally Z-shaped pattern.Type: GrantFiled: May 19, 1992Date of Patent: January 12, 1993Assignee: Spendrup and Associates, Inc.Inventors: Steve R. Cowley, Bradley S. McCoy

Patent number: 5147427Abstract: An air filtration system that reduces positive and/or negative resistance by eliminating duct work to and from the to-be-filtered room. The air filtering system forms a common wall with the to-be-filtered room permitting dirty air to move easily and quickly through to the cleaning process. Through the use of vertical baffles and reverse pulsed jets, debris is easily and efficiently collected in drawers or trays. Because of the modular design of the invention, it is easily placed on a trailer and transported to a locale which is to be cleaned within a flexible room (i.e. bridges, building exteriors, airplanes, etc.).Type: GrantFiled: July 15, 1991Date of Patent: September 15, 1992Assignee: Stripping Technologies Inc.Inventors: Kenneth E. Abbot, Patrick J. Lyons

Patent number: 5137555Abstract: The present invention is an apparatus utilizing a mesh pad, located on the front of a mist extractor through which water may drain and air may pass. Water flows at a sufficient rate through said mesh pad to drain the mist extractor, and air flowing through said mesh pad is filtered of moisture and does not entrain moisture from the mist extractor.Type: GrantFiled: December 22, 1988Date of Patent: August 11, 1992Assignee: Peerless Manufacturing CompanyInventor: Kenneth J. Fewel, Jr.
