A device for purifying liquid in a reservoir and including a vacuum chamber (1) having an inflow opening (2) and an outflow opening (3) adapted to communicate with the liquid in the reservoir through a feed conduit (4) and a return conduit (5), respectively. The return conduit (5) is provided with a pump (6) and the vacuum chamber is connected with a vacuum pump (7). The device further includes a filter cartridge (8) provided with a plurality of filter elements, each having a flow side communicating with a central passage (26) and a flow side opening into the periphery of the filter cartridge (8). The filter cartridge (8) is arranged inside the vacuum chamber, the central passage (26) of the filter cartridge communicating with the inflow opening (2) of the vacuum chamber.
摘要:
The invention relates to a device for maintaining and cleaning a working medium (3), especially coolants, oils, grinding water, vehicle washing water and washing baths, which can be delivered to at least one filter by at least one line, especially a flexible tube (6). According to the invention, a vacuum and/or pressure-generating device is allocated to the filter (13) or to a filter pad (41, 41.1) and the filter can be approached from several sides. The working medium (3) enters the filter pad and passes from the inside of said filter pad (41, 41.1) to a transfer section (12).
摘要:
A vacuum filter device is disclosed which includes a filter body (11) which is adapted to receive in fluid-tight, sealed relationship a pair of closed containers (15,16) for solutions to be filtered by means of a membrane filter positioned within the filter body. A vacuum port (23) in the filter body (11) communicates with the downstream side of the membrane and a vent passageway (60;70) also located in the filter body (11) communicates with the closed sample container to serve as a vent to atmospheric pressure. The vent passageway is sealed by an air permeable hydrophobic filter to prevent the sample solutions from leaking out of the device during normal use.
摘要:
A wet flue gas desulfurization process wherein sulfur dioxide present in flue gas is absorbed into a slurry containing a calcium compound, the slurry having sulfur dioxide absorbed therein is oxidized to form a gypsum slurry, and gypsum is separated and recovered from the gypsum slurry, which comprises the steps of dipping a part of a circulating filtering surface of a suction filter into the gypsum slurry so as to cause gypsum to adhere the filtering surface, carrying the gypsum-bearing filtering surface above the surface of the gypsum slurry, sucking out the liquid phase through the filtering surface to form a dehydrated gypsum layer thereon, and removing the gypsum layer from the filtering surface, as well as an apparatus for carrying out this process.

Badebecken mit integrierter Filtereinrichtung, insbesondere Whirlpool mit Einstrahldüsen für ein Wasser-Luft-Gemisch, mit wenigstens einer Umwälzpumpe (15, 20), die druckseitig und saugseitig mit dem Beckeninnenraum in Verbindung steht, mit einem außen am Becken angeordneten Aufnahmeraum (8) für eine auswechselbare hohle Filterpatrone (13), der über wenigstens eine im Bereich der Mindestfüllhöhe (7) ausmündende Zulaufleitung (6) mit dem Beckeninnenraum verbunden ist und der im Bodenbereich eine mit der Saugseite der Umwälzpumpe (20) über eine Saugleitung (14) verbundene Absaugöffnung aufweist, die mit dem Innenraum der Filterpatrone (13) in Verbindung steht.
摘要:
System for separating solids from slurry containing a separable solid in a liquid carrier, such as an industrial waste. The slurry is flowed into a separation chamber positioned over a slower moving foraminous medium to effect cross-flow separation of liquid from the slurry in an initial stage and followed by separation of solids from the slurry in a second stage all the separation being effected employing a single forwardly moving filtration medium. The flow rate of liquid, the rate of travel of the foraminous medium, and the differential pressure across the foraminous medium, as established by the pressure exerted by the flowing liquid on the foraminous medium and the relative pressure underneath the foraminous medium, are controlled at different locations along the length of the separation chamber to provide optimum steady-state separation for a given waste stream.
