摘要： A filter system comprising a tank and a filter assembly removably mounted therein. The filter assembly includes a plurality of filter tubes in fluid communication with a plenum chamber on the bottom thereof. The plenum chamber is open on its bottom, and rests on the bottom of the filter tank. Suitable seals maintain the fluid integrity of the plenum chamber against the bottom of the tank. The filtrate leaves the plenum chamber through an outlet port in the bottom of the tank.The inlet port is also in the bottom of the tank, and the fluid to be filtered passes upwardly through a channel formed in the center of the plenum chamber. The top of the tank is sealed by a U-shaped gasket, with the cover of the tank resting on the gasket. No auxiliary flanges are needed to provide a top seal. The cover of the tank is raised by a lifting mechanism, and is rotatable away from the top of the tank to permit access to the tank. When the cover is to be returned to its closing position, a keying mechanism automatically seats the cover in the proper position.

摘要： A particulate filter medium is formed of a sintered composite of 0.5 micron diameter quartz fibers and 2 micron diameter stainless steel fibers. A preferred composition is about 40 vol. % quartz and about 60 vol. % stainless steel fibers. The media is sintered at about 1100.degree. C. to bond the stainless steel fibers into a cage network which holds the quartz fibers. High filter efficiency and low flow resistance are provided by the smaller quartz fibers. High strength is provided by the stainless steel fibers. The resulting media has a high efficiency and low pressure drop similar to the standard HEPA media, with tensile strength at least four times greater, and a maximum operating temperature of about 550.degree. C. The invention also includes methods to form the composite media and a HEPA filter utilizing the composite media. The filter media can be used to filter particles in both liquids and gases.

摘要： A pressure filter for separating a liquor from mud liquor slurry and for concentrating a filter cake as a heavy slurry discharge comprising a tank having a ring of filter elements supported by a plate which separates the filter tank from a filtrate chamber. The feed enters the tank under pressure through an enlarged feed cylinder tube located in the center of the ring of filter elements. In the backwashing mode of operation the feed rate is maintained or increased to assist in displacing filter cake from the filter elements.

摘要： Filter for separating solid particles from an oil in which a vessel is divided into three compartments by a pair of tube sheets, with a plurality of hollow mesh screen filter cartridges, having open tops and bottoms being supported between the tube sheets. Oil to be filtered is introduced into the top compartment and flows into the interior of the cartridge and is filtered by radial flow through the cartridge into the intermediate compartment. The oil flow washes solids from the screen through the open bottom and into the bottom compartment.
