Abstract:
An apparatus especially suitable for filtering out particulate material from a carrier fluid such asflue gases is disclosed herein. This assembly utilizes a main vessel defining an interior compartment and having an inlet and separate outlet. A number of filter assemblies are disposed within the vessel compartment and supported therein in spaced relationship with one another and with the vessel itself by means of a single tubular member which also serves as a discharge pipe between the filter assemblies and the vessel's outlet.
Abstract:
The present invention concerns a pleated filter media (12) extending in an axial direction (x), a transverse direction (y) that is perpendicular to the axial direction (x), and a lateral direction (z) that is perpendicular to the axial direction (x) and perpendicular to the transverse direction (y), the pleated filter media (12) comprising: a plurality of pleats (24) comprised of pleat segments (26) extending in the axial direction (x) between first and second axial ends (28a, 28b) and extending in the transverse direction (y) between first and second sets of pleat tips (30a, 30b) which are at least partially defined by first and second sets of bend lines (22a, 22b); wherein axial flow channels (32) are defined between the pleat segments (26) in the lateral direction (z); wherein the plurality of pleats (24) has a width in the transverse direction (y) that varies along the axial direction (x) at least along a portion of the plurality of pleats; and wherein the portion of the plurality of pleats comprises at least a first linear portion (34a) extending at an angle to the axial direction (x) and a second linear portion (37b) extending at an angle to the axial direction (x).
Abstract:
The invention relates to a screening belt machine (1) comprising a section (10) that acts as a screen and is disposed transversely to the flow direction (4) of a liquid flow (5). The endless screening belt (6) is designed as an endless screening belt (6) that can be flexibly folded, compressed, or bent transversely to its direction of movement.
Abstract:
The invention relates to a filtering device for fluids, comprising a filter housing (1). At least one filtering element (9) which is in the form of a filter cartridge and which defines a longitudinal axis (11) can be received in said filter housing. The filter cartridge has an end cap (17) on at least one end, said end cap forming an enclosure for the corresponding end edge of the filtering material (23, 35). The end cap can be fixed on an element receiving means (13), which interacts with the bottom part (5) of the filter housing (1), in order to fix the position of the filtering element (9) in the functional position thereof. The element receiving means forms a fluid path for the cleaned fluid exiting the filtering hollow chamber (19) of the filtering element (9). The filtering device is characterized in that the element receiving means (13) contains a valve arrangement (55) which blocks the fluid path (35), and in that a control device (79, 83) which releases the valve arrangement (55) in the functional position is provided on the end cap (17) of the filtering element (9), said end cap being fixed on the element receiving means (13).
Abstract:
A filter device having at least one filter housing (1), in which at least one filter element (11) that defines a longitudinal axis can be received in the form of a filter cartridge which has on at least one end an end cap (19) forming an enclosure for the relevant end rim of the filter material (23, 25), which end cap, for fixing the position of the filter element (11) in its functional position, can be fixed on an element receiver (13) that interacts with the bottom part (7) of the filter housing (1), is characterized in that the element receiver (13) and the assigned end cap (19) of the filter element (11), on the parts thereof (17 and 15) coming into engagement with one another in the functional position of the filter element are provided with shape irregularities which are matched to one another which enable the engagement in a positional relationship directed towards one another.
Abstract:
Le procédé de filtration d'air dans un appareil du type cyclofiltre consiste à effectuer, dans la partie basse en forme de jupe (16) de la cartouche filtrante (4), une réduction de la vitesse ascensionnelle de l'air à filtrer. La cartouche filtrante (4) comporte, dans sa jupe (16), des perforations (15) qui permettent d'accroître la surface d'entrée de l'air à dépoussiérer, réduisant ainsi la vitesse ascensionnelle de l'air à l'entrée basse de ladite jupe. Le diamètre et la densité des perforations (15) sont adaptés au type de poussières et déchets en suspension dans l'air.
Abstract:
Des éléments de filtrage d'air (32) à barrière en papier ondulé ont des panneaux planaires de filtrage qui sont nettoyés par un système de nettoyage à jet d'air inversé. Un ou plusieurs distributeurs ou têtes (74) d'air de nettoyage ayant des formes spécifiques comprennent une pluralité de tuyères ou d'ajutages (90) agencés selon une configuration prédéterminée pour fournir un jet d'air (92) totalement enveloppant déchargé dans un tuyau d'écoulement (54) immédiatement en aval de la chambre d'écoulement d'air pur (50) d'un élément de filtrage (37) généralement tubulaire. L'agencement du jet crée une zone temporairement étanche à la pression dans le tuyau d'écoulement (54) et entraîne une quantité considérable d'air ambiant dans le jet à écoulement inversé de façon à nettoyer de manière approfondie des éléments de filtrage (32), en enlevant des mottes de poussière de leurs surfaces extérieures. L'agencement à jets multiples réduit l'espace total occupé par le système de nettoyage à jet inversé et permet d'obtenir un plus grand débit-masse d'air de nettoyage. Des têtes ou des collecteurs (74) à ajutages multiples peuvent être agencés selon pratiquement n'importe quelle figure géométrique pour obtenir la configuration voulue du jet. Les éléments du panneau planaire de filtrage permettent d'obtenir de hautes vitesses frontales du milieu de nettoyage associées à des basses vitesses tubulaires d'écoulement. Des filtres ovales (150) ont une zone d'écoulement d'air pur plus grande qu'une pluralité d'éléments cylindriques (152) agencés dans une enveloppe de dimensions identiques.
