Abstract: Pleated paper barrier type air filter elements are cleaned by a reverse air jet cleaning system which includes one or more specifically shaped cleaning air valves (74) in which a plurality of jet nozzles or orifices are arranged in a predetermined pattern to provide a totally enveloping air jet which is discharged into a flow tube immediately downstream of the clean air flow chamber of a generally tubular filter element. The jet pattern provides a temporary pressure seal within the flow tube and entrains a substantial amount of ambient air into the reverse flow jet to thoroughly flush elements to clean dust cake from the exterior surfaces thereof. The multiple jet arrangement reduces the overall space occupied by the reverse jet cleaning system and provides a larger mass flow of cleaning air. Multiple jet orifice valves may be configured in virtually any geometric shape to provide a desired jet pattern.

Abstract: A drill cuttings conveying and collection system (50) for handling drill cuttings produced by an earth drilling rig (20). A generally tubular head member (52) is adapted to be extendable with respect to the rig deck (38) into engagement with the ground around the drillhole (35) for conducting a bailing air flowstream laden with drill cuttings to an enclosure (70) wherein coarse cuttings are separated from the flowstream by gravitational and inertia forces and deposited on the ground at a point remote from the drillhole. Relatively fine cuttings are conveyed from the coarse cuttings separating enclosure (70) to a filter and dust collection unit (88) to provide total collection of entrained particles utilizing inertial and impingement separation techniques. The system efficiency is such that a variable capacity suction pump on the dust collection unit (88) is required to operate at only 1.0 to 1.5 times the volumetric flow rate of bailing air injected into the drillhole.

Abstract: A reverse air jet cleaning system for impingement or porous media type air filter elements includes one or more specifically shaped cleaning air manifolds or heads in which a plurality of jet nozzles or orifices are arranged in a predetermined pattern to provide a totally enveloping air jet which is discharged into a flow tube immediately downstream of the clean air flow chamber of a generally tubular filter element. The jet pattern provides a temporary pressure seal within the flow tube and entrains a substantial amount of ambient air into the reverse flow jet to thoroughly flush or flood the filter element to clean the dust cake from the exterior surface of the element. The multiple jet arrangement reduces the overall space occupied by the reverse jet cleaning system and provides a larger mass flow of cleaning air to thoroughly flush the surfaces of the filter element. The multiple jet orifice heads or manifolds may be configured in virtually any geometric shape to provide the desired jet pattern and are not limited to use in conjunction with cylindrical tubular type filter elements.

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.

Abstract: Single and multiple porous media impingement type air filter elements are disposed in filter housings which provide access to the filter elements from top opening doors or plenums in the housing for service or repair of the elements. Housing sections defining the plenums are provided with mechanism to lift and swing the housing sections clear of the filter opening, and the housing sections are movable to relieve excess working pressure differentials across the filter element. In two embodiments the filter elements are each in sealing engagement with a shield which is also sealingly engaged with a top wall or door of the filter housing to minimize contamination of personnel servicing or replacing the filter elements. Clean air is discharged through a downwardly extending clean air flow tube into a discharge plenum or chamber and particulate material separated from the air flow stream falls into a material collecting hopper portion which may be defined in part by a sloping wall separating the clean air flow chamber from the particulate material collection chamber. Filter element backflushing air control valves may be located in the bottom of the filter housing to enhance the accessibility of the filter elements from the top of the housing and to minimize overall height of the filter apparatus.
