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.
摘要翻译：柱浮选池包括流体容器，外部安装的微泡发生器，用于将来自发生器的气泡和液体的加压混合物导入容器的导管，其特征在于在引入气泡之前抑制气泡的聚结和扩大，以及用于将气泡/液体混合物引入容器中并将混合物均匀地分布在整个容器横截面中的装置。通过限制混合导电导管的长度以及通过设计导管以提供基本上均匀且连续的流动直径来抑制气泡的聚结和扩大。流动直径的均匀连续性降低了流体流动的局部扰动，否则流体流动的不均匀性会导致气流的聚结和扩大。下游端的管道的内径不大于上游端的内径，以保持混合物流的压力和速度基本上恒定。多个导管优选用于将混合物从气泡发生器引导到容器。容器内的管道的端部是柔性的并且被定位成提供气泡/液体混合物通过容器横截面的均匀分布。

摘要： An air injector assembly has an input port and an output port connected by a bypass bore and tapered bore. Fitted within the tapered bore is an air injector mechanism which contains a throat and a venturi nozzle portion. The opening of the bypass bore can be varied so that the amount of water passing therethrough is controlled to regulate the pressure being received at the input port which represents the back pressure on a pump. By varying the opening of the bypass bore, the back pressure of the pump can be regulated so that the pump may operate safely. Air is injected into the air injector assembly when water is pushed through the throat and into the venturi nozzle. A cavity is formed at the junction where the throat is coupled to the venturi nozzle so that air can be drawn thereat to aerate and oxidize the water passing therethrough. By aerating and oxidizing the water, hydrogen sulfide is removed and iron is precipitated, and can be removed later. An air supply assembly provides a safety valve which only allows air to be drawn into the air injector assembly.

摘要： A method for producing amorphous aluminocarbonate compounds which comprises continuously recirculating a first aqueous solution from a reaction vessel through a recycle system and injecting a gas comprising carbon dioxide into the first solution at a turbulent area located in the recycle system. A second aqueous solution is added to the first solution while the gas injection is continued, and the pH of the resulting mixture is maintained in the approximate range of from 8 to 10. The gas injection is discontinued when the entire amount of the second solution has been added to the first solution, in order to allow further precipitation of the amorphous compound. The method is particularly adapted for producing amorphous sodium aluminocarbonate and sodium magnesium aluminocarbonate.

摘要： A non-homogenous mixture of liquid and gas is fed into a vessel to form a body of gas above a pool of liquid. Liquid is fed from the pool through a discharge pipe containing a constriction forming a venturi and gas is drawn from the gas body through a pipe extending through the liquid pool into the discharge pipe to effect mixing of the liquid and the gas in the venturi. Perforations in the discharge pipe adjust the amounts of gas and liquid leaving the vessel to maintain both liquid and gas within the vessel.

摘要： A jet aeration header is disclosed, for use in water and wastewater process and treatment system. The header comprises a first pipe defining a cylindrical water passage, a second pipe extending parallel to the first pipe and defining a cylindrical air passage, at least one water outlet conduit connected to the first pipe to allow water to be expelled out of the water passage, an air-feed pipe connecting the second pipe to the outlet conduit to allow air to be delivered from the air passage to the water flowing through this conduit, and a venturi cone mounted in the outlet conduit to allow air to be FED from the air passage and be mixed with a water expelled through the outlet conduit. This basic structure is improved in that each outlet conduit is connected to the first pipe by a hollow nipple laterally projecting from the first pipe, the nipple having a large, flared inlet solidly connected to the first pipe in such a manner that no sharp edges or protrusions are left inside the water passage, that would favor fibrous materials to attach, accumulate and clog the outlet conduit. Each water outlet conduit is defined by the transverse bar section of a T-shaped pipe, the stem section of the T-shaped pipe being connected to the air-feed pipe. The venturi cone is mounted into the transverse bar section of the T-shaped pipe forming the conduit outlet so that the wide inlet of the venturi cone is adjacent the outlet of the nipple to which the T-shaped pipe is connected.
摘要翻译：公开了一种用于水和废水处理和处理系统的喷射式曝气头。集管包括限定圆柱形水通道的第一管，平行于第一管延伸并限定圆柱形空气通道的第二管，连接到第一管的至少一个出水管，以允许水从水通道中排出，将第二管道连接到出口管道的空气供给管，以允许空气从空气通道传送到流过该管道的水;以及文丘里锥体，安装在出口导管中，以允许空气从空气中进入FED 并通过出口导管排出的水混合。这种基本结构得到改进，即每个出口导管通过从第一管横向伸出的中空的接头连接到第一管，该接头具有一个固定地连接到第一管的大的，扩口的入口，使得没有锋利的边缘或突出物留在水通道内，这将有利于纤维材料附着，积聚和阻塞出口导管。每个出水管由T型管的横杆部分限定，T形管的杆段连接到供气管。文丘里锥安装在形成导管出口的T形管的横杆部分中，使得文丘里锥的宽入口与T形管连接的接头的出口相邻。

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 water conditioning apparatus and method wherein raw water is supplied to a plurality of axially aligned stripping chambers to form a cove shaped sheet within said stripping chambers and to cause an aspiration of air in each of the stripping chambers. Alternating high and low pressure zones are formed in the stripping chambers to enhance the air stripping of the water. The water is discharged through an outlet nozzle where the water sprays against the side wall of the nozzle to cause the water droplets to coalesce.

摘要： The present invention relates to an improved method and apparatus for dispersing a gas into a liquid. Gas is injected into a liquid and the flowing gas-liquid mixture is accelerated by a flow area contraction to at least sonic flow velocity, and subsequently decelerated by a flow area expansion to subsonic velocity. The attendant shock waves disperse the gas in the liquid. Preferred embodiments include off-centering the gas injection direction from the centerline of the contracting flow area and controlling the pressure at the exit of the expanding flow area.
