A filter includes a bed of particulate solids for removal of contaminants from a fluid directed in a downstream direction therethrough. A barrier is located downstream of the bed of particulate solids and includes an anchoring member having flexible members joined thereto and projecting outwardly therefrom. The flexible members are closely spaced to each other for providing a closely-spaced network of flexible members to establish multiple barrier layers in the downstream direction of fluid flow through the barrier. In one embodiment the barrier is in the form of a planar member generally coextensive with a bottom wall of the filter and includes a plurality of anchoring members spaced-apart horizontally from each other. In another embodiment the barrier is in the form of a strainer with the anchoring members being spaced-apart vertically from each other and with the flexible members joined thereto being spaced transversely along the anchoring members to provide the multiple barrier layers.
In order to filter out of the dielectric the microscopically small spherical particles removed by spark erosion [???] machines, a labyrinth filter is provided, containing at least one filter unit with a pressure receptacle (21) loosely filled with filter grains. The intake surface area is relatively small by comparison to the height of the column through which the liquid to be filtered flows, and the filter pump is matched to these two dimensions in such a way as to cause the dielectric to flow through the labyrinth at a rate of at least 2 meters per minute. This leads to the formation of low-pressure zones behind the individual filter grains, in which zones the microscopically small spherical particles removed by the erosion [???] process become trapped.
An apparatus for removing harmful objects comprising a cylindrical casing having an inlet and an outlet, a fill-up section for a granular or lump treating material for adsorbing or resolving the harmful objects. An inlet obstructive plate provided within the casing and spaced from the inlet for covering the area corresponding to the inlet from the inside of the casing. A surrounding obstructive plate provided in at least an upper portion of the fill-up section among the upper portion, a middle portion between the top and bottom and a lower portion thereof to project into the fill-up section from the interior of the casing and a supporting plate for supporting the treating material.
A modular adsorption plant comprises one or more transportable cargo containers which hold the various adsorbent beds, pumping apparatus and so on which comprise the plant. The containers are easily transportable, and may be rapidly assembled in modular fashion to produce a large capacity plant.
5873929 - Gas treatment bottle - Owned by L'Air Liquide, Societe Anonyme Pour L'Etude et L'Exploitation des Procedes Georges Claude (Paris Cedex,FR)
A gas treatment bottle comprises at least one gas dispenser (24;50) and has a distributor (25;51) intended to be fixed in a gas treatment bottle (10) in front of an inlet or outlet orifice (18;56). The distributor (25;51) has a head (26) which covers the orifice and has an openworked end wall (28) and an openworked side wall (30), typically inclined in the direction of the end wall (28) and surrounding it. The degree of openworking in the side wall (30) is greater than the degree of openworking in the end wall (28).
An adsorber having an upright longitudinal extent includes two perforated parallel panels extending within the vessel formed therein and spaced apart defining an adsorbent mass chamber. The adsorbent mass is in two longitudinal parts having a first part of fine particles and a second part of larger particles. The gas to be treated is circulated horizontally between the two perforated panels. This device allows the treatment cycle to be less than 60 seconds with the same or better performance. This adsorber and process are preferably used for the separation of oxygen from air.
