Patent number: 5653786Abstract: A high capacity marine separator (30) is disclosed which uses a first stage formed by an inertial vane separator (32), a second stage formed by a coalescer stage (36) and a third stage formed by an inertial vane separator (34). The coalescer stage (36) is canted from vertical relative to the air flow direction which increases the surface area for air flow, increases the drainage rate of water from the coalescer section and provides an improved air flow distribution to the second inertial vane separator with higher velocities near the top of the second inertial vane separator. The inertial vane separators (32, 34) have flush cavities to reduce obstruction to air flow and have vanes that are greater than three inches in wavelength and spaced greater than one inch apart. The marine separator is capable of flow velocities of 50 standard feet per second.Type: GrantFiled: December 20, 1995Date of Patent: August 5, 1997Assignee: Peerless Manufacturing CompanyInventors: David Taylor, Alan A.

Patent number: 5626651Abstract: A method of removing particulates from a gas stream involves introducing the gas stream in a turbulent flow condition into and through a flow passage situated over spaced surfaces defining a plurality of stagnant, turbulent-free regions of gas in which there is no net gas flow and which communicate with said gas stream and arranging the stagnant regions near the flow passage so that turbulent eddies of said gas stream carrying suspended particulates penetrate spaces between the surfaces and then decay in said stagnant regions defined therebetween where said particulates are trapped and deposited mechanically on said surfaces within each of said regions. The deposits accumulate at bottoms of the regions and can be periodically removed.Type: GrantFiled: April 29, 1996Date of Patent: May 6, 1997Assignees: Francis A. L.

Patent number: 4540421Abstract: It is an object of the invention to provide a unit for discharging material, such as lengths of paper strip from an air stream. As shown in FIG. 1, a flow of air with suspended waste material enters, as illustrated by the arrow 1, along a duct 2. The flow is into an entry section 4 of a perforated duct 5 located within an outer casing 6 which forms an air duct. At the downstream end, the duct 5 leads into a bend section 7 which is perforated on the outside of the bend and at the sides. The flow of air or gas continues out of the open end 8 of the casing 6 as indicated by the arrow 9, while the suspended solid material is deflected by the bend section into a discharge duct 11, down which the solid material falls by gravity. The duct 11 is shown as including two pairs of optional isolating flap valves 12 so as to provide an air lock arrangement so that the air flow in the duct 11 is substantially zero.Type: GrantFiled: January 26, 1984Date of Patent: September 10, 1985Assignee: Matthews and Yates LimitedInventor: David J.

Patent number: 4478619Abstract: Incoming air passes through one or more orifices in an expansion head forming small jets which impinge upon a downwardly facing cylindrical wall for moving water droplets and the like into a sump. A curved shield located above the cylindrical wall serves to move the incoming air upwardly in a relatively uniform billowing mass. A filter cartridge includes, in the order described from the lowermost to the topmost, at least three individual cells. The first cell contains cotton waste for absorbing water, oil, particulate matter and the like. The second cell contains a material for capturing such things as oil aerosols, for example. The uppermost cell, again, contains cotton waste for removing particulate matter, such as dust from the molecular sieves, for example, and any residual moisture. The cells are spaced from one another by spring-loaded means to maintain the separation. The spaced relation of the cells prevents channeling of pressurized air through the cells.Type: GrantFiled: May 2, 1983Date of Patent: October 23, 1984Inventors: Andrew G. Arends, Gary W. Arends
