摘要： The invention concerns a device for diffusing gas microbubbles in a liquid. Said device can be used for generating microbubbles required for clarification by flotation of a liquid loaded with suspended matter. It can also be used for facilitating dissolution of the gas in the liquid. The method and the device of the invention are particularly designed to replace the air dissolving device (that is, the microbubble generator) in installations for clarification by dissolved air flotation. The device consists of a rotating gas diffuser housed in a body (2) wherein the liquid circulates. The high rotational speed of the diffuser enables to generate considerable friction between the liquid and the surface of the diffuser, thereby drawing from the diffuser very fine bubbles and dispersing them in the liquid.

摘要： A separation system (10) is disclosed for use with a treatment tank (14), such as a flotation tank or decant tank, to separate particles and/or gases from a liquid suspension stream (20). The system is coupled to a liquid source comprising the liquid suspension stream. A hydrocyclone (18) directs the liquid suspension stream through a first chamber or passage in a generally helical fashion (32) along a cylindrical wall (24) where bubbles-to-particulate aggregates (16) are formed. A second chamber (34) encloses an outlet (26) of the hydrocyclone and may take many forms, including a generally concentric or parabolic form, and acts to decelerate the liquid and deliver the liquid to a third chamber (38) from which bubbles (40) escape the liquid. The liquid drops from the third chamber into the treatment tank in a manner which only minimally disturbs liquid (44) which is already in the treatment tank.

摘要： The invention refers to an apparatus for producing water saturated with air under high pressure and preferably intended for dispersion in flotation plants, which apparatus comprises a preferably standing cylindrical pressure vessel (21) which during operation to a controlled level is partly filled with pressurized water flowing through said vessel and out through an outlet in the lower part of the vessel and partly with continuously added compressed air, whereby during the passage of the water through the vessel (21) air is dissolved in the water. The supply of pressurized water to the apparatus is arranged at the upper part of the pressure vessel (21) by means of a spray-nozzle (24) or similar arrangement which splits the water flow. The spray-nozzle is so designed that at least part of the water flow sprays and essentially covers the inner walls, of the upper, during operation air filled portion, of the vessel (21) by means of a water curtain which portion is supplied with compressed air through a conduit (27) arranged in the wall of the vessel in this portion.

摘要： An apparatus (12) and method for deinking waste paper pulp using a foam flotation process to recycle printed waste paper for the manufacture of new paper. Pulped printed paper is fed as a slurry to an inlet (26) of a shallow tank (14). Internal guide walls (16) in the tank (14) establish a flow path (26) from the inlet to an outlet (28). The walls (16) are sized and positioned to create a generally uniform cross-sectional flow area. A plurality of modules (20) are disposed along the flow path (18). Each module (20) includes at least one injector (22) that aerates the flow and an extractor (24) that removes floated ink foam. A portion of the flow from each module (22) is recycled to an upstream module, preferably by a conduit (46a) and associated pump (46b). In a preferred form, an injector (22) (or injectors) alone located at the inlet is fed by the next downstream module (22) and an extractor (24) alone is located near the outlet (28). The invention also includes a main recycling loop (50) from the downstream end (18a) of the flow path to the upstream end. This main recycling loop (50) has a large flow rate compared to the recycled flow between the modules (22).

摘要： In an aeration apparatus in which a dense dispersion of bubbles is formed within a substantially vertical pipe (3) by the emission of liquid under pressure through a downwardly facing nozzle (2) into the upper end of the pipe (3) and the entrainment of air or other gas through inlet (6), the performance of the apparatus is improved or modified by the incorporation of a draft tube (30) within the pipe. The draft tube (30) serves to provide an ideal cross-section to control the jet issuing from the nozzle (2) and inhibit the formation of large bubbles in the pipe (3). The draft tube may be provided with holes (32) and may adapt various tapering configurations as disclosed in different embodiments of the invention. The use of multiple nozzles (2) and corresponding draft tubes within the pipe (3) is also described.

摘要： Aeration apparatus in which a dense dispersion of bubbles is generated within a conduit or tube (3) having its lower end (5) immersed in a body of liquid (4) is provided with a diffuser plate (10) extending outwardly and upwardly from the outer periphery of the conduit (3), and immersed in the liquid (4). The diffuser plate (10) is typically conical or dish shaped and has a number of holes therethrough permitting bubbles to be released from the underside of the diffuser plate in an even dispersion through the holes into the body of liquid (4). Embodiments are also described wherein a gap is provided between the diffuser plate and the outer periphery of the conduit (3), allowing solids accumulating on the top surface of the plate to be dispersed through the gap.
