    • Process of recovering a constituent of a process effluent, such as an effluent of a process for making a preform from which an optical fiber is drawn. The effluent is directed into a scrubber (40) of a loop (20) where it is treated with an aqueous solution to provide a solvent mixture which comprises particulates and a solvent solution including the constituent, e.g., germanium. Subsequently, the solvent mixture is moved into a first filter system (55) which provides a filtrate free of particulates above a first size that is returned to the scrubber for reuse and a residue. Then the residue from the first filter system is moved into a second filter system (80) which provides a filtrate free of particulates larger than a second size that is smaller than the first size and a residue. The filtrate from the second filter system also is returned to the scrubber for reuse while the residue from the second filter system is recirculated therethrough. When the constituent, e.g., germanium, concentration reaches a predetermined level, portions of the residue from the second filter system are withdrawn and subsequently treated with a precipitating agent to recover the constituent, e.g., germanium.
    • 回收过程流出物的组分的方法,例如用于制造预先形成光纤的预成型体的流程的流出物。 将流出物引入环(20)的洗涤器(40)中,其中用水溶液处理,以提供包含微粒和包含成分例如锗的溶剂溶液的溶剂混合物。 随后,将溶剂混合物移入第一过滤系统(55),该第一过滤器系统(55)提供不含高于第一大小的微粒的滤液,其返回到洗涤器中用于再利用和残留。 然后将来自第一过滤系统的残余物移入第二过滤器系统(80),其提供不含比第一尺寸小的第二尺寸的颗粒的滤液和残余物。 来自第二过滤器系统的滤液也被返回到洗涤器中以便重新使用,而来自第二过滤器系统的残余物通过其再循环。 当组分(例如锗)浓度达到预定水平时,来自第二过滤器系统的残余物的部分被取出,随后用沉淀剂处理以回收成分,例如锗。

    • A cooling tower for the cooling water flowing from the condenser of a steam engine or from the condensers of several steam engines. The cooling tower is fitted with built-in elements having a large surface which form a heat exchange area to which the cooling water is brought. In the reverse current of the cooling water, the built-in, large-surface elements are traversed by a rising flow of air. The cooling tower is fitted in the cooling air stream with a smoke gas conduit for the admission of cleansed, preferably wet-cleansed smoke gases; the smoke gas conduit is connected with one or more gas exhaust pipes, the exit profiles of which open into the cooling air stream above the heat exchange zone. In order to improve admission of cleansed smoke gases into the cooling air stream of a cooling tower (1), the invention proposes that rotors (8) be provided in the gas exhaust pipes (6) in the area of their exit cross-sections (7). For this purpose it is also possible to design each gas exhaust pipe so as to be rotatable around its longitudinal axis, with the angle of inclination of the gas exhaust pipes being changeable.
    • 用于从蒸汽发动机冷凝器或几个蒸汽发动机的冷凝器流出的冷却水的冷却塔。 冷却塔内装有大面积的内置元件,形成冷却水所带来的热交换区域。 在冷却水的反向电流中,内置的大表面元件由空气流量上升。 冷却塔装在冷却空气流中,带有烟气管道,用于进入清洁的,优选湿法清洁的烟雾气体; 烟气管道与一个或多个排气管连接,排气管通过热交换区上方的冷却空气流。 为了改善清洁的烟气进入冷却塔(1)的冷却空气流中,本发明提出在排气管(6)的出口横截面( 7)。 为此,还可以设计每个排气管,以便能够围绕其纵向轴线旋转,同时排气管的倾斜角度是可变的。
