    摘要： A system for sparging aerated water into a column for the froth flotation of minerals, and located in the lower portion of the column, consists of water and air supply headers connected to a supply of pressurized water and air, respectively. The headers comprise a number of water and air passages, each having shut off valves. A multiplicity of sparger tubes is arranged, in one or more horizontal planes, either radially towards the column center or parallel to each other from opposite sides of the column. Each sparger pipe comprises a mixing tee attached to a water passage and an air passage, and a perforated portion provided with a number of small openings. The number of openings in each pipe is determined by the cross-sectional area covered by the sparger pipe. The openings may be arranged upwardly and/or downwardly at an angle in the range of about 5.degree. to 90.degree. from the horizontal. The openings are preferably arranged in a single row and directed vertically downwardly, or in two parallel rows and directed radially downwardly at an angle of 5.degree. to 75.degree. from the horizontal. Each opening is provided with a wear-resistant material, preferably in the form of an insert and preferably made of tungsten carbide, to reduce erosion of the openings. The number of openings is chosen such that the air bubbles exit from the openings and rise in the column substantially evenly distributed over the entire cross section of the column.

    摘要翻译： 用于将充气水喷入用于矿物浮沫的柱中并位于塔的下部的系统由分别连接到加压水和空气供应的水和空气供应头组成。 集管包括多个水和空气通道，每个具有截止阀。 多个喷射管在一个或多个水平平面中沿着柱的中心径向地布置或者相对于塔的相对侧布置。 每个喷射管包括连接到水通道和空气通道的混合三通和设有多个小开口的穿孔部分。 每个管道中的开口数由排气管覆盖的横截面面积决定。 开口可以与水平面成约5°至90°的角度向上和/或向下布置。 开口优选地布置成一排并且垂直向下或两个平行的排，并且以水平方向以5°至75°的角度径向向下引导。 每个开口设置有耐磨材料，优选为插入件的形式，优选地由碳化钨制成，以减少开口的侵蚀。 选择开口的数量使得气泡从开口排出并在柱中上升，基本均匀地分布在柱的整个横截面上。

    摘要： The invention relates to a floating suction device for a pump wherein the pickup point for the pump suction can be adjusted to various elevations. An aeration feature may be combined with the floating suction device to sparge compressed gas into an oil/hydrocarbon layer to promote movement of hydrocarbons from that layer into a topmost hydrocarbon rich layer for ultimate pumping through the floating suction device.

    摘要： A static diffuser for use within the water tank of an ozonator system. The diffuser comprises a depending water pipe into which water is fed under pressure by an external pump. The lower end of the pipe flares outward and has an internal fixed cone which combines with the flared end of the pipe to provide an annular laterally directed water discharge. The annular discharge includes angularly directed vanes to enhance the water discharge and assist in forming a high velocity outwardly directed circular sheet of water. The pipe is surrounded, in spaced relation, by a shroud through which the ozone is introduced. The shroud is provided with an annular slot outward of the pipe discharge, the shape of the shroud at the slot forming a modified 360.degree. circular venturi whereby the discharging high velocity sheet of water creates a negative pressure drawing the ozone therewith into the surrounding body of water for a ozonation thereof.

    摘要： A whirlpool bath unit in which aerated water is circulated in a bathtub. The incoming water flows through a restricted orifice in a jet mixer unit to form a narrow jet stream which is directed into a larger final orifice and then into the bathtub. An air passage led into said larger final orifice of the jet mixer unit draws air that is sucked by the jet stream of water. The combination of air and jet stream is directed into the bathtub to form a circulating whirlpool. The bathtub level is maintained at a constant level by a suitably located vertical tube mounted over the bathtub drain, with the jet mixer unit fastened to said vertical tube.

    摘要： The system employs a plurality of submerged diffuser units spaced along a supply air feed line and an air-water discharge valve device disposed at the downstream end of the feed line to permit expulsion of substantially all water present in the feed line at the commencement of an operating period. The diffuser units are in the form of air jet reaction propellers, which effect vertical circulation by both mechanical and diffused air pumping.

    摘要： A single or double sparger unit is held accurately positioned on a header by the combination of a boss formed on the saddle portion of the sparger unit, and which projects into an aperture in the header through which air is supplied to the sparger unit, and a spring system embracing the header and drawing the sparger unit into sealed relationship with the header. A saddle shaped portion of the sparger unit, surrounding the boss, engages the header through a sealing gasket. The spring system includes one or more stainless steel spring fasteners. Each fastener includes a band with a spring at each end hooked through a hole in the band and hooked to the sparger unit.
