Abstract:
A gas turbine air intake system uses a filter element (42) having a seal member with radial projections and radial recesses. The seal member forms a seal with components (104) on the tube sheet (38) of the system and at the end opposite of the tube sheet. At the end opposite of the tube sheet, there can be an assembly cover (112), or alternatively, an additional filter cartridge.
Abstract:
A modular portable dusty air cleaner comprises a detachable bin, a dirty gas distributor, an aperture plate, a plurality of tubular filters, a roof, a clean-gas chamber, a dust collection chamber, and a pulse-jet assembly. The dirty gas distributor is positioned to distribute dirty gas into the dust collection chamber from a periphery of the plurality of filters. The detachable bin depends from the dirty gas distributor. The aperture plate forms at least a partial ceiling for the bin. The plurality of tubular filters hangs into the bin from the apertures of the plate, one filter per aperture. The roof is positioned above the aperture plate. The clean-gas chamber is defined between the plate and the roof. The pulse-jet assembly is positioned at least partly in the clean-gas chamber. The pulse-jet assembly includes a plurality of nozzles for pulsing jets of gas down the plurality of filters, one nozzle per filter to dislodge accumulated dust into the detachable bin.
Abstract:
A dual flow filter element includes inner and outer closed loop filter media and inlet and outlet end caps, and having a given sliape-in-shape configuration. A support frame extends axially from one of the end caps toward the other end cap and terminates a t a termination position between one-fourth and three-fourths of the axial distance between the inlet and outlet ends. Combinations using pleated filter media include a first group of pleat tip ends which are exposed, and a second group of pleat tip ends which are fully potted. One embodiment includes axiaily offset inner and outer closed loop filter media.
Abstract:
Filter systems described herein include one or more spacer elements positioned in the dirty air chamber along with the filter elements attached to the spacer elements. The dirty air inlet delivers a dirty air stream into the dirty air chamber along a dirty air flow axis.
Abstract:
A filter apparatus comprises a filter stack including a plurality of porous ceramic plates that are axially spaced from one another to define plurality of axially spaced apart radial flow areas. In one example, the filter stack is mounted within a housing. In further examples, the plurality of porous ceramic plates alternate between a first set of porous ceramic plates that are nested with a second set of porous ceramic plates. In still further examples, at least one of the sides of the porous ceramic plates defines a plurality of radial flutes arranged in a radial array.
Abstract:
Various methods and apparatus are disclosed that relate to one or more aspects of a filter structure that may remove contaminants from a stream of fluid. In various aspects the filter structure includes a front portion having a first orientation and a rear portion having a second orientation unique from the first orientation.
Abstract:
Um ein Reinigen einer von Filtereinheiten einer Filteranordnung eines zum Behandeln von Gut vorgesehenen Prozessbehälters am Ort der Filtereinheiten ohne Ausbau derselben (Cleaning in Place - CIP) zu verbessern, sieht die Erfindung eine Filteranordnung zum Reinigen von mit Partikeln verunreinigten Gasen, mit mindestens einer Filtereinheit mit einem Außen- und einem Innenfilter (3.1, 3.2) vor, wobei der Außen- und Innenfilter unter Freigabe einer Öffnung (3.4) in ihrem unteren Bereich relativ zueinander bewegbar sind. Weiter ist ein erfindungsgemäßes Verfahren zum Reinigen dadurch gekennzeichnet, dass der reingasseitige Bereich der Filtereinheit mittels einer in diesen ragenden Reinigungslanze unter Freigabe eines Spaltes (3.4) im unteren Bereich von Außen- und Innenfilter eingesprühtes Reinigungsf luid gereinigt wird.
Abstract:
Provided is a filter bag for use in a dust collector which increases a filter area greatly even with a simple structure, and which makes size of the dust collector compact, to thereby reduce an installation area of the dust collector, and uniformly distributing an air pressure to thereby increase a dust removal effect as well as to enable a worker to easily manufacture the dust collector regardless of a quality of a material to thus provide a wide application range. The filter bag includes: a cylindrical filter cloth (32) which is supported by a filter cage (31); and a venturi tube (35) which is combined with the upper end of the filter cage 31, and forms an air supply path so that pressurized air is supplied to the inside of the filter cloth (32), wherein the filter cloth (32) comprises an cylindrical outer filter cloth (33) which is provided in the outside of the filter cage (31), and an inner filter cloth (34) whose lower portion is combined with the inner circumference of the inner circumferential surface at the lower end of the outer filter cloth (33) so as to be opened and which is extended toward the venturi tube (35).
Abstract:
Die Erfindung betrifft eine Filteranordnung mit metallischem Filterelement für einen Filter zur Entstaubung eines Gases zur Anwendung für hohe Temperaturen. Die Filteranordnung weist zwei metallische Filterelemente (3 und 4) auf, die koaxial zueinander angeordnet sind und ein hohlzylinderförmiges Volumen (5) einschließen. An der Oberseite des Filterelementes (1) ist eine ringförmige Öffnung (9) für den Austritt des gereinigten Gases ausgebildet. An der dieser Öffnung (9) für den Austritt des gereinigten Gases gegenüberliegenden Seite sind die metallischen Filterelemente (3 und 4) durch einen das hohlzylinderförmige Volumen (5) verschließenden Kreisring (6) verbunden. Der Innenraum des inneren zylindrischen Metallfilterelementes (4) ist in der Ebene der Öffnung (9) für den Austritt des gereinigten Gases dicht verschlossen. Beabstandet zur Öffnung (9) für den Austritt des gereinigten Gases ist eine dem mittleren Durchmesser der ringförmigen Öffnung (9) für den Austritt des gereinigten Gases angepasste Ringspaltdüse (12) zentrisch zur ringförmigen Öffnung (9) für den Austritt des gereinigten Gases angeordnet. Mittels der Ringspaltdüse (12) wird eine ringförmige Gasströmung erzeugt, die tief in das hohlzyliderförmige Volumen (5) zwischen den metallischen Filterelementen (3 und 4) eindringt und eine effektive Abreinigung von an den metallischen Filterellementen (3 und 4) anhaftendem Staub und Partikeln bewirkt.
