摘要： A process of removing carbon dioxide from a liquor in a vessel comprises the step of continuously passing a portion of the liquor into a sidestream and introducing discrete bubbles of between 0.005 mm and 1.0 mm diameter of nitrogen rich gas into the liquor before returning it to the vessel in which the nitrogen acts to adsorb carbon dioxide from the liquor and is then expelled from the liquor as an off-gas. The process also includes introducing a gas to be dissolved in the liquor into the sidestream as discrete bubbles having a diameter of between 0.005 mm and 1.0 mm.

摘要： Apparatus and methods for the controlled introduction of submicron-sized bubbles into a fluid stream. The gas-micronizer apparatus of the present invention operates in a manner that maximizes the turbulence of the liquid flow stream at the interface of the porous surface while flowing essentially parallel to the porous surface through which gas enters to form bubbles, thereby ensuring that the gas streams through the pores are dispersed quickly into the bulk liquid flow and/or are of sufficiently small size as to behave as rigid spheres that do not easily coalesce. In a preferred embodiment, the membrane is of generally tubular shape with a nominal surface porosity of 25-30%, and an average pore size below 1 micron (and ideally about 0.2 micron). Fluid is provided to the inlet of the membrane element (by means of a pump) through an inwardly tapered approach conduit. An outwardly tapered exit conduit extends from the outlet end of the element, thereby forming a venturi arrangement. Surrounding the membrane is a sealed chamber into which the gas is supplied under pressure.

摘要： A dispersion water nozzle passes pressurized water containing dissolved air into a flotation clarifier. A throttle part of the nozzle is composed of a cylinder or spherical valve member, into which, the main flow through passage and a crosswise flow through passage are formed. The crosswise flow through passage has a smaller cross-sectional area. The throttle part is followed by a tubular flow equalization part. The nozzle is easy to clean by changing the flow passages and flow directions in the throttle member.

摘要： A column flotation cell includes a fluid vessel, an exteriorly mounted microbubble generator, conduits for conducting a pressurized mixture of bubbles and liquid from the generator to the vessel, features for inhibiting the coalescence and enlargement of the bubbles prior to their introduction into the vessel, and an arrangement for introducing the bubble/liquid mixture into the vessel and for distributing the mixture uniformly throughout the vessel cross-section. Coalescence and enlargement of the bubbles are inhibited by limiting the length of the mixture-conducting conduits, and by designing the conduits so as to provide a substantially uniform and continuous flow diameter. The uniform and continuous nature of the flow diameter reduces local disturbances of fluid flow which would otherwise occur at discontinuities in the flow path, tending to cause coalescence and enlargement of the bubbles. The inside diameter of the conduit on the downstream end is not greater than the inside diameter on the upstream end so as to maintain the pressure and velocity of the mixture flow substantially constant. A plurality of conduits are preferably used for conducting the mixture from the bubble generator to the vessel. The ends of the conduits within the vessel are flexible and are positioned so as to provide uniform distribution of the bubble/liquid mixture through the vessel cross-section.

摘要： A method and apparatus for generating microbubbles in a flowing liquid stream for use in a froth flotation system. The system utilizes a microbubble generator having a tubular housing with an inlet end and an outlet end. Located coaxially within the housing is an inner member with an elongated, tapered, exterior surface. A porous tubular sleeve is mounted between the housing and the inner member coaxially therewith to define with the cylindrical interior surface of the housing an elongated air chamber of annular cross section. The porous sleeve has a cylindrical inner surface that defines with the exterior surface of the inner member an elongated liquid flow chamber of thin, annular cross section. An aqueous liquid is supplied to the liquid flow chamber at a relatively high flow rate and air under pressure is supplied to the air chamber so that air is forced radially inwardly through the porous sleeve to be diffused in the form of microbubbles in the flowing stream.

摘要： A plurality of aerators are arranged in a preselected pattern on the floor of a basin or lagoon containing waste water. Compressed air is supplied to the aerators by aeration pipes anchored by hanger brackets to the floor of the basin. Each aerator has a porous diffuser plate through which the air is passed and released into the waste water in the form of ultra fine air bubbles less than 60 microns in diameters. The air bubbles are generated in an intense manner with a high rate of air flow to increase the mixing action and liquid circulation pattern, and to create turbulent boils at the surface which provide surface aeration from atmospheric air and re-entrainment of air from eddy current circulation.

摘要： Method and apparatus for bubble shearing are disclosed in which nascent bubbles are formed by flowing gas through the very small capillary openings of a gas diffusing surface into a moving liquid that shears the nascent bubbles off as it moves past the capillary openings. In the apparatus disclosed, the gas diffusing surface forms one wall of a liquid transmitting slot through which the shearing liquid flows as it shears off fine gas bubbles.A gas transmitting body or gas "bar" for use in the bubble shearing apparatus is disclosed. The gas transmitting body has at least one wall with a plurality of gas transmitting passages extending therethrough terminating in capillary openings. The maximum size of the capillary openings is given, as well as the maximum distance of the most remote capillary openings from an edge of the gas diffusing surface defining one boundary thereof. Improved and preferred values for these parameters are also given. Other structural features of the gas transmitting body are disclosed.A rapid and efficient method of fabricating the gas transmitting body of this invention in which the plurality of gas transmitting passages through the body is defined by discrete tubes embedded in the wall of the gas transmitting body as a matrix is also disclosed. Suitable and preferred methods of applying binder to form the matrix, as well as methods of positioning the discrete capillary tubes to be embedded in the matrix, are disclosed.

摘要： A microbubble generation device comprises a liquid inlet (101), a gas inlet (104), a bubble flow outlet (103), and a gas-liquid mixing chamber (102). An air-permeable hole having an angle structure is provided at a gas-liquid interface of the gas-liquid mixing chamber (102), and a pointed end of the angle structure of the air-permeable hole points to a liquid flow direction. The bubbles generated by the device are extremely small in diameter, prolonging a duration the bubbles stay in the liquid phase, and enhancing gas-liquid mass transfer efficiency.
