Abstract: Apparatuses for separating solid catalyst particles from a Fluid Catalytic Cracking (FCC) vapor are provided. In one embodiment, an apparatus includes a vessel formed with a vessel wall. A conduit is positioned within the vessel and is configured to direct flow of an FCC vapor-solid stream. The apparatus also includes a channel positioned within the vessel and in fluid communication with the conduit. The channel has a channel inlet with an inlet cross-sectional area and a channel outlet with an outlet cross-sectional area less than about 75% of the inlet cross-sectional area. The channel outlet is configured to direct the vapor-solid stream tangentially toward the vessel wall to separate the solid catalyst particles from the FCC vapor.

Abstract: A conventional dust-catcher for blast furnace gas comprises a pressure vessel, with a gas inlet and outlet dome (14), a separation chamber (16) and a lower dust hopper (18), and a diffuser pipe (26) extending axially through the gas inlet and outlet dome (14) into the separation chamber (16). To increase the separation efficiency of such a dust hopper (18), it is proposed to centrally arrange a flow deflecting chamber (50, 50?), having a smaller cross-section than the separation chamber (16), in the separation chamber (16), so that there remains an annular settlement chamber (52) between the inner wall of the separation chamber (16). The diffuser pipe (26) is connected to this flow deflecting chamber (50, 50?) so as to axially discharge a downward gas flow into the top end of the flow deflecting chamber (50, 50?), wherein this downward gas flow is deflected upward.

Abstract: A separation housing houses a rotor with multiple suspension chambers. Each chamber has a radially extending web portion between two rotating discs. An orifice is provided through the radially extending web portion. Another web portion urges gas radially out of the rotor. Passages through the rotating disks permit entry of gas and solid particle mixtures into the suspension chambers at high speed traveling toward each other in a suspension adjacent to the orifice. The web portion that urges gas out of the chamber pulls gas away from the suspension zone. Gas moving through the aperture and into a clean gas chamber pulls gas in the opposite direction. The result is gas in the suspension zone being fixed relative to the rotor or changing direction. Centrifugal force moves solid particles radially out of the chamber.

Abstract: A modular powder recovery apparatus includes a base unit, one or more cartridge filters, and a wrapper that at least partially encloses the cartridge filters. The wrapper is designed to allow additional wrappers to be vertically stacked thereon to increase the overall height of the wrapper, thus permitting additional filter capacity without changing the base unit. The base unit is modular in design so that the size of the apparatus may be increased with a minimum of cost and waste.

Abstract: A cleaning system for removing undesirable material from an outer surface of a critical or sensitive element relatively moving in a fluid comprises a tubular duct for the flow of the fluid medium and having an entrance end an exit end. The entrance end is oriented generally in the opposite direction of the relatively moving fluid to receive the fluid medium. The tubular duct narrows down in cross-sectional area to define a Venturi section at the exit end thereby substantially increasing the exit fluid flow velocity. The exit end is placed adjacent to and generally directed toward the outer surface causing the high-velocity exit fluid stream to remove the undesirable materials through the momentum thereof.

Abstract: In order to remove particulate matter from the exhaust gases which flow into the turbine impeller scroll of a internal combustion engine turbocharger, a separator which settles or centrifugally separates the solids from the gases is disposed between the engine manifold and the turbocharger. The separator is arranged to communicate with the turbocharger waste gate so that collected particulate matter is carried out of the device when the valve is opened to vent excessive back pressure.

Abstract: A cyclone type particle separator comprising a lower cone with a particle outlet, an intermediate cylinder and an upper truncated cone. An inlet is opened at the intermediate cylinder tangentially or involutedly thereof and adjacent to the upper end of the lower cone so that the particle-laden gas can freely spiral upward in the intermediate cylinder and the upper truncated cone while the particles separated drop into the lower cone. The top wall of the upper truncated cone is spaced apart from the inlet by a suitable distance, and upper particle trapping chambers are extended tangentially and outwardly from the upper truncated cone and is contiguous with the top wall so that the particles separated in the upper truncated cone adjacent to the top wall thereof can be trapped and collected in the upper trapping chambers.

Abstract: In paper-making operations and the like, fibers of wood are frequently transported through piping as an entrainment in steam. An apparatus is disclosed for separating such entrainment and removing the fibers at one station and the steam at another station. Rotating blades give the entrainment a circular or rotating action whereby the heavier fibers move outwardly by centrifugal force to contact the wall from which the blades scrape the fibers and hurl them to discharge. The fiber-free steam is removed along an axial line perpendicular to the direction of movement of the separated fibers under the influence of a second set of blades.

Abstract: A method and apparatus are disclosed for separating components from a flog medium by means of centrifugal force. The flowing medium travels through two stages. In the first stage a spin is generated and in the second stage the actual material separation is accomplished in one or several separating devices by means of one or several whirling or eddy sources. The apparatus includes a spin generator housing and separator chambers, whereby spin conduits extend into the separator chambers toward exhaust pipes to such an extent that a spacing is provided between the spin conduit and the exhaust pipe. At least one exhaust suction is tangentially effective in the area of this spacing.

Abstract: Pollution control apparatus and a method for removing particulate matter from a gas at temperatures of up to about 3000.degree. F. are disclosed comprising a gas centrifuge having effluent and influent openings and a spray nozzle positioned to inject a stream of a refrigerated fluid at the effluent gas passing through the centrifuge. The spray nozzle is arranged to force particulate matter against the walls of the gas centrifuge in order to facilitate removal of particles in the gas stream and also to cool the gas to a low temperature after which it may be either discharged into the atmosphere or processed through a moving filter at low temperatures to further remove any finer particles in the gas passing through the apparatus. The lower temperatures of the gas emanating from the gas centrifuge allow the use of a cloth or synthetic fiber filter such as a Dacron (trademark) filter.

Abstract: A precleaner assembly for the air intake system of a heavy duty vehicle ejects duct particles and other heavy material from the incoming air stream so that the heavy particles will not clog the normal vehicle air cleaner, thereby greatly increasing its life. The precleaner assembly includes an inlet which faces the direction of vehicle movement, so ambient air is rammed into the inlet of the precleaner. The rammed air is directed through turning vanes located in a diverging portion of the assembly to induce a vortex or spiral flow component to the fluid. Centrifugal force generated by movement of the dust particles in the spiral path causes the latter to be centrifuged radially outwardly with respect to the direction of movement of the flow stream. These heavy particles therefore are concentrated in the radial outermost portion of the flow stream, which is ejected from the assembly, so that the remaining portion of the flow stream will be relatively free of the heavy particles.

Abstract: An apparatus for feeding a carding machine with fiber material having a shaft which is fed by a preceding feed shaft. The fiber material is conveyed into the feed shaft by means of a stream of air flowing through a conveying conduit. An air circulating passage is connected between the feed shaft and the filling shaft. An air conveying device is disposed in the air circulating passage for conveying the stream of air emerging from the feed shaft into the filling shaft for compressing the fiber material therein.

Abstract: An apparatus for separating gases from fluids, which apparatus includes a closed cylindrical receptacle and a cylindrical insert which divides the interior of the receptacle into an annular outer part and a cylindrical inner part. The outer part is provided with a tangential inlet for the fluid. Near the top, an opening connects the outer part to the inner part, the latter being provided with a ventilation device. The outer annular part is divided in the axial direction by a partition which ascends spirally from the tangential inlet approximately in a complete turn in the direction of the upper end face cover of the receptacle. The connection opening is formed by an annular clearance which extends over nearly the entire circumference of the receptacle. A similar annular clearance at the bottom of the receptacle connects the inner cylindrical part with the outer annular part, the latter having a tangential discharge outlet in this region.

Abstract: The disclosure concerns a separator for removing broken engine parts and other debris from the hot gases passing fro the exhaust manifold of an engine to the inlet of an associated turbocharger. The separator includes an annular separation chamber in which the gases are swirled by stationary vanes to effect centrifugal separation of the debris, and a cylindrical screen which filters the gases as they leave the separation chamber. The screen is mounted in cantilever fashion within the separator casing and carries, at its free end, the vanes and a deflector which directs inlet flow radially outward to the separation chamber. The vanes are freely mounted in slots formed in the screen, where they are held captive by the slot margins and the deflector, and the tips of the vanes are spaced radially from the surrounding casing of the separator.

Abstract: The inlet assembly is mounted within a separator vessel and comprises a housing similar in shape to that of a snail shell. This housing has a generally spiral side wall closed in by top and bottom end walls. A feed pipe delivers pressurized crude oil tangentially to the inner end of the spiral side wall so that it rotates outwardly, following the length of said wall, to an outlet communicating with the interior of the separator vessel. Gas is separated by centrifugation in the smaller radius central portion of the housing and then the liquid flow velocity is reduced by expansion of the stream in the larger radius outer portion. Improvements in gas separation and emulsion reduction have been observed from use of the assembly.

Abstract: Efficient separations of immiscible fluids of different density can be obtained in compact separation systems by passing the fluid mixture through an inertial separator having an N.sub.D value of 50 or below under specified conditions of non-atomizing flow.

Abstract: A turbocharger and intake air cleaning device for use with internal combustion engines. A collection spout is mounted tangent to the volute of the diffuser housing at a position from the turbocharger's discharge port which is upstream relative to the direction of rotation of air within the housing. A nozzle is mounted in the distal end of the collection spout. Dirt and other foreign matter carried in the rotating air stream migrates by centrifugal action into the collection spout where it is separated from compressed air flowing through the discharge port. An opening in the nozzle expels the foreign matter while at the same time limiting air leakage so as to maintain boost pressure within the diffuser.

Abstract: An apparatus for cleaning air charged with contaminants, especially fibers and dust, comprising a pre-separator and a dust filter arranged after the pre-separator. At least one movable suction nozzle is effective at the surface of the dust filter. The pre-separator, constructed as a body of rotation, possesses an inlet portion structured for producing a spin flow and a jacket portion structured as a sieve surface which is surrounded by a rotatably mounted filter drum of the dust filter. A cylindrical filter body of the filter drum has operatively associated therewith at the inner surface thereof the movable suction nozzle, and drive means are operatively connected with the suction nozzle and filter drum.

Abstract: A mechanism for the removal of impurity particles from a gas for cleansing the gas including directing the gas in a circular axial flow through an elongate axially extending circular separator chamber; introducing liquid droplets at the inlet end of the chamber for capturing the particles, passing the droplets through a perforate wall on the chamber into an outer annular wall and removing the liquid from the outer chamber through an air lock valve. In one form the speed of the gas is increased at the location of the droplet introduction by a decrease in the annular size of the chamber, and in another form, the perforate collecting wall is tapered to diminish in size. The size of the chamber is such that the distance from the droplet introduction to the wall is no greater than 25 cm.
