    • A rotating gas diffuser for shearing fine gas bubbles from the surface thereof when the diffuser is immersed in a body of liquid and rotated therein. The rotatable shaft of the diffuser carries a disk like member defining at least one gas plenum having a porous wall out of which gas introduced into the plenum can pass to form nascent gas bubbles which are then sheared off by the viscous shear forces exerted by the liquid in which the disk is rotating. Preferably both the top wall and the bottom wall forming the gas plenum or plenums are porous. The ratio of the overall diameter of the disk to the maximum thickness of the disk in the gas diffusing area occupied by the plenums is at least about 32:1. Improved results are obtained when this ratio is at least about 48:1, more improvement is obtained with a ratio of at least about 64:1, and still greater improvement with a ratio of at least about 128:1. The preferred value of the ratio is at least about 256:1.
    • 一种旋转气体扩散器,用于当扩散器浸入液体并在其中旋转时,从其表面剪切细小的气泡。 扩散器的可旋转轴承载盘状构件,其限定至少一个具有多孔壁的气室,引入气室的气体可通过该多孔壁形成新生气泡,然后由液体施加的粘性剪切力剪切 其中盘旋转。 优选地,形成气体增压室或增压室的顶壁和底壁都是多孔的。 磁盘的总直径与由气室占据的气体扩散区域中的盘的最大厚度的比率至少为约32:1。 当该比例为至少约48:1时,获得了更好的结果,以至少约64:1的比率获得更多的改进,并且以至少约128:1的比率进一步改善。 该比率的优选值为至少约256:1。

    • An aerator for dispersing a gas in a liquid comprises an elongate tube having openings at both ends and having mounted therein one or more turbines which are free to rotate about the longitudinal axis thereof. The tube is vertically submerged in a liquid, for example in a lake or pond of water. Air or another gas is supplied to the lower end of the tube. Gas bubbles rising through the tube cause an upward flow of liquid therethrough. The turbines are rotated solely by this upward flow of gas and liquid. The turbine rotation causes the gas bubbles to be broken up into a vast number of very much smaller gas bubbles which are dispersed throughout the liquid, so that optimum gas absorption may occur. The turbines are preferably so constructed that adjacent turbines (if more than one turbine is used) rotate either at different speeds or in counter directions to thus optimize the breaking up of the gas bubbles. A method for aerating a liquid is thereby provided.
    • 用于将气体分散在液体中的充气器包括在两端具有开口并且在其中安装有一个或多个涡轮的细长管,其可绕其纵向轴线自由旋转。 管垂直浸没在液体中,例如在湖泊或水池中。 空气或另一种气体被供应到管的下端。 通过管子上升的气泡导致液体向上流动。 涡轮机仅由气体和液体的向上流动旋转。 涡轮机旋转导致气泡被分解成分散在整个液体中的大量非常小的气泡,从而可能发生最佳的气体吸收。 涡轮机优选地被构造成使得相邻涡轮机(如果使用多于一个涡轮机)以不同的速度或相反的方向旋转,从而优化气泡的分解。 从而提供一种使液体充气的方法。

    • PROBLEM TO BE SOLVED: To provide an underwater aerator which can enhance aeration action, reduce loads at the time of start, prevent blocking of a foreign substance, alleviate maintenance operation, and reduce a production and a running costs. SOLUTION: A partition wall partitioning a liquid supply path 4w and an air supply path 4a provides an impeller 4 formed on a blade 4c between the lower face 5d of a middle plate provided with an air inlet port 5s by drilling and the top face 7u of a suction cover provided with the liquid inlet port 7s by drilling so as to be freely rotated to be accommodated in a guide casing 6. The liquid supply path 4w and the air supply path 4a at the tip portion of periphery of the partition wall on the blade back face 4r side communicate 4h. A middle impeller 4m is provided at the periphery of the liquid supply path 4w. The gap between the blade lower end face 4d and the suction cover upper face 7u is formed large in the liquid inlet port 7s, narrow toward the periphery containing the tongue part of a guide vane and grinding vessel-like. A plurality of stand tappets 8 and strainer protrusions 9 is integrally provided with protrusion at the lower end face of the periphery of the lower wall 6d of the guide casing, and a shape of the upper face 6o of the upper wall between gas liquid discharge paths is provided with recess at the down grade oblique face widened towards the periphery.
