Date Aug. 18, 1994A suitably conditioned slurry feed is introduced to a trough from which it is distributed into a slurry layer-flow forming chamber provided with a discharge weir which discharges an evenly spread layer of slurry onto an inclined plate feeding into a mixing passage and then into a vessel. Recirculated slurry from the vessel is also fed into the mixing passage via a recycle gate which forms it into a layer of slurry. An array of clean liquid jets accelerates thin gas envelopes and impinges between layers of slurry and causes intensive mixing of all streams in the mixing passage. A high shear rate produces high intensity turbulence and shears gas into very small bubbles. A multiphase mixture flow is discharged from the mixing passage into the vessel, where it flows past one or more longitudinal stabilizing baffles. Gas bubbles loaded with hydrophobic particles disengage from the stream, rise toward the liquid surface and are diverted by bubble-diverting guides toward a froth discharge end of the vessel. A layer of froth travels toward a froth weir where it is discharged. Residual slurry leaves a discharge launder via a weir to a following flotation cell or process stage. | ||||||

| Hydrogen sulfide or other gaseous component is removed from a gas stream containing the same by distribution of the gas stream in the form of fine bubbles by a rotary impeller and stationary shroud arrangement at a submerged location in an aqueous iron or other transition metal chelate solution, or other suitable catalyst, contained in an enclosed reaction vessel.

| Water clarifying apparatus has a cylindrical tank where particulate contaminants suspended in raw water are separated using flotation techniques. A set of concentric mutually spaced, conical plates are positioned in the flotation tank. The plates rotate about the tank, preferably in unison with a (i) header that distributes equal quantities of raw water to each annular zone in the tank defined by the conical plates and (ii) a scoop for removing the contaminants which form a floated sludge layer. A screw conveyor is located in a discharge pipe of the floated sludge scoop. A infrared sludge detection array in a window in the side wall of the tank senses the sludge-water interface. Air dissolving tubes operating in parallel have common feeds and discharges coupled through three way valves operated to pressurize a closed volume of water with high pressure air in one tube while reloading and discharging the other tube. | ||||||

| Components, usually but not exclusively gaseous components, are removed in a liquid medium from gas streams and chemically converted into an insoluble phase or physically removed. Specifically, hydrogen sulfide may be removed from gas streams by oxidation in aqueous chelated transition metal solution in a modified agitated flotation cell. A gas-liquid contact apparatus, generally a combined chemical reactor and solid product separation device, comprising such modified agitated flotation cell also is described. In order to effect efficient mass transfer and rapid reaction, gas bubbles containing hydrogen sulfide and oxygen are formed by rotating an impeller at a blade tip velocity of at least about 350 in/sec. to achieve the required shear. To assist in the reaction, a surrounding shroud has a plurality of openings, generally of aspect ratio of approximately 1, of equal diameter and arranged in uniform pattern, such as to provide a gas flow therethrough less than about 0.02 lb/min/opening in the shroud. In general, the gas velocity index is at least about 18 per second per opening, preferably at least about 24 per second per opening. Each of the openings has an area corresponding to an equivalent diameter less than about one inch. | ||||||

A pulp suspension of waste paper which is laden with air bubbles is introduced into a flotation cell. Fine air bubbles rise through the pulp suspension toward the top. Printing ink and other impurities are deposited on the bubbles which form a foam layer on the surface of the pulp suspension. The foam which is laden with impurities is drawn off from the surface. The fibers which have been subjected to preliminary purification in this manner sink downwardly. For reducing the number of cells connected in series to fewer than a third, while obtaining the same degree of whiteness, the fibers which were subjected to preliminary purification are drawn off and are once again supplied to the flotation cell in the form of an air-laden pulp suspension. Alternatively, instead of the air-laden pulp suspension, a water-air suspension can be injected. The air bubbles which are thus introduced once again rise toward the top and traverse the sinking fibers in a counterflow. As a result, an intensive air-pulp contact is created. | ||||||

| 1465801 Dispersing gases in liquids; froth flotation apparatus OUTOKUMPU OY 3 June 1974 [5 June 1973] 24480/74 Heading B1C and B2X In a method of dispersing a gas in a liquid or slurry, (e.g. for froth flotation) by means of a rotor within a stator, the increase in hydrostatic pressure with increasing depth is compensated by a hydraulic pressure correspondingly changing with depth in order to keep the total liquid pressure substantially constant over the surface over which the gas is dispersed; this is done by arranging for the ring of liquid between the rotor and stator to increase in thickness with depth so that the centrifugal force acting on the liquid ring produces the compensating dynamic pressure. As shown in Fig. 1 gas is supplied through a hollow shaft and dispersed through passages 5 between which are "grooves" 8 through which the slurry circulates; the envelope of the rotor is cylindrical while the stator is shaped so that the clearance between them increases downwardly. In other embodiments the rotor may narrow downwardly while the inner envelope of the stator is cylindrical, or both may increase in diameter downwardly with increasing clearance (Figs. 4-7, not shown). In Fig. 1 the "grooves" 8 are closed at the bottom, but they may be open at both ends or shrouded at the top (see Figs. 2 and 3, not shown). The gas passages 5 in the rotor may be omitted (Fig. 8, not shown) and the gas introduced above the rotor through a downcover surrounding the rotor shaft (Fig. 12, not shown). | ||||||

| The invention concerns a flotation apparatus for separating impurities, such as printing ink, or the like, from a fiber suspension that has been formed from waste paper. The apparatus includes a container for flotation of the suspension. A drive shaft extends into the container, either from above or below. A feed opening for suspension is defined at the bottom of the container. On the drive shaft is a pump impeller for impelling suspension into the container and downstream along the drive shaft. From the pump impeller there is a rotor located on the drive shaft for dispersing air that is introduced to the container by an air feed conduit which emits air into the region of the rotor. The drive shaft itself may serve as the air feed conduit and it may have air outlets at either or both of the pump impeller and the rotor. A foam withdrawal means for withdrawing the foam of impurities generated in the flotation apparatus has an inlet positioned at the axis of the cylinder which is at the axis of the rotor. | ||||||

| Apparatus for de-inking waste paper pulp using a foam flotation process in which the deinked slurry is to be recycled for the production of paper. The old paper is pulped (slushed), mixed with water and flotation- and other chemicals, to produce a slurry which is introduced into the flotation tank. Movement of the slurry through the flotation tank is achieved by the positioning of one or more water injector nozzles with air inlets which causes a swirling rotation from the injector towards a central outlet. Froth or foam bubbles float to the surface of the slurry carrying ink particles. A baffle plate leads the floated froth or foam and ink particles to a vacuum actuated outlet. | ||||||
