| 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 flotation machine consists of a flotation chamber and a rotating gas diffuser. The flotation chamber has a lower mixing chamber and an upper quiescent zone for maximizing float accumulation. The rotating diffuser produces ultra fine bubbles as small as 50 microns in diameter. The size of the bubble diameter can be controlled and produced in any size from less than 50 microns to greater than 10 mm to enable flotation of various materials and/or various sized fractions of materials. The ultra fine bubbles are produced by the diffuser in the same size range as bubbles produced by dissolved air flotation, but without the necessity of pressurizing gas in a first tank followed by depressurizing in a second tank. Since the diffuser is located within the flotation chamber and can vary bubble size, it also provides the advantage of sparged air flotation. This rotating diffuser configuration is a low drag thin disc and, when combined with a specially designed flotation chamber, embodies a flotation machine which produces higher product yields over a wider range of feed size fractions utilizing significantly less energy. | ||||||

| A flotator for use in benefication, coal dressing, wet refining and so forth, incorporating a surface flotation technic. The flotator has a funnel-shaped liquid cell having a bottom of an area smaller than that of the top opening. A bubbling device is constituted by an upper sleeve partly immersed in the liquid contained by the cell, a lower sleeve disposed coaxially with the upper sleeve and fully immersed in the liquid. The upper end of the lower sleeve is spaced by a predetermined distance from the lower end of the upper sleeve to form therebetween a spaced region located at a small depth from the liquid surface. The bubbling device further has a rotary blade unit constituted by upper and lower blades separated by a flat partition plate. The rotary blade unit is adapted to rotate around the common axis of the upper and lower sleeves, and has a thickness or axial height substantially equal to the aforementioned predetermined distance in the spaced region, and is located such that the flat partition plate is located at the heightwise mid point of the spaced region. The flotator further has a liquid surface stabilizer constituted by a frusto-conical member disposed around the bubbling device and adapted to deflect the liquid downwardly. Further, provided are a feeding passage having a feed gate opening in the bottom area of the cell and a discharging passage having a discharge gate spaced from both of the feed gate and the lower edge of the liquid surface stabilizer so as to avoid the "short-circuiting" of the liquid. | ||||||

| PURPOSE: To enhance flotation capacity by using both-face blade rotary body to cause effective foaming and liquid surface stabilizer to stabilize liquid surface. CONSTITUTION: A rotary body 3 having blades 3b at lower and upper sides of partition plate 3c is concemtrically mounted in the upper and lower cylinders 2a, 2b. Multiple dispersers 5 are mounted on the periphery facing the rotary member 3. The outer periphery is installed with a liquid stabilizer 7. Air and liquid are mixed by rotation of the rotary body 3, are subjected to centrifugal force and divided into fine particles by the dispersers 5, are downwardly deflected by thr stabilizer 7, and jetted out without disturbing liquid surface. Liquid sucked from the lower cylinder 2b contains only a little bubbles, so that useless power due to bubbles is not used. Because liquid is supplied from the supply route 9, the liquid is not flowed from outlet route 10 without passing bubble section 6. COPYRIGHT: (C)1980,JPO&Japio | ||||||

| 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 treatment procedure, using a flocculation tank (10) and a separation zone, consists of delimiting a central zone (2) in the flocculation tank with the aid of a submerged guide tube (2A) and an agitator (8) in which a turbulent axial flow of the raw fluid and a flocculent is created. - The flow is divided and distributed by a static device (5A) at the outlet end of the guide tube that opposes its rotation, and the mixture is circulated in a peripheral zone (3) taking it back to the intake end of the central zone, with part of the mixture being passed to the separation zone. The flow in the central zone is maintained at a rate equivalent to between 1 and 20 times the input flow of the raw fluid to be treated, with the flocculent introduced before the fluid enters the tank, in the tank, or in the central zone. | ||||||

| PROBLEM TO BE SOLVED: To efficiently remove a component from a gas phase or a liquid phase or the like by operating a combination of rotary impeller and a side plate under a specific condition, rapidly allowing substance to move between the gas and the liquid with a pumping work of the rotary impeller, and excellently stirring the liquid phase. SOLUTION: The rotary impeller 28 surrounded with a cylindrical side plate 34 opened with plural holes and provided with plural blades 32 is arranged at an immersed position (a deep liquid side) in the liquid, and the gas phase is fed below the liquid level with its rotation and the gas phase is distributed into the liquid phase in the form of many gas bubbles by shear force between the blade 32 and may the holes. Gas phase bubbles having a gas-liquid mixed phase are formed in the liquid phase inside the side plate 32. At this time, the structure of the device and the operational parameter are respectively quantitated such that shear effect index SEI value determined with a gas flow rate against the impeller and the height of the impeller blade, etc., becomes about 1-10, and an effective shear coefficient ESI value becomes about 1-2500. | ||||||
