Study on Water Processing by Foam Film for High Reducing of Water Use

泡沫材料在各种水处理中的应用因其节水、节能的直接效果而受到广泛关注。通过用气体代替大部分比热的水，特别是在高温处理中，利用比热小的水（如空气），可以节省水，并大大减少升温和隔热所需的能量。它注意到在高原边界产生对洗涤作用和染色极其有效的液体流动，在泡沫中或由泡沫膜与基板的接触部分构成，积极地移动气泡。为此，构建了该液体流动的速度测量系统。根据以往的研究，泡沫膜是通过向烧瓶中的表面活性剂溶液中注入气体（空气）来生成的。将此处产生的气泡或薄膜引入设置在s ...更多信息 在该显微镜装置中设置高速摄像机，并且能够观察在通常条件下极其困难的高速液体流。通过玻璃管等将观察后的气泡引入到捕集器中，并进行了液体流动观察和流速测量的条件设定。观察对象是基本上由表面活性剂溶液形成的透明无色泡沫膜，假设作为检测器的微小固体聚苯乙烯颗粒聚苯乙烯等的移动，考虑液体流动进行分析，作为观察的结果，使速度比泡沫膜的通过速度快的液体流进入平台边界，并且必须确认其方向并不是恒定的，而是产生了所谓的湍流。另外，当速度元素被分为两个方向（与泡沫膜成直角和平行）时，平行元素较大。结果表明，沿高原边界长度方向的流体流动沿着较活跃。少

The application of the foams to various water processing is widely noticed for its immediate effects in water saving and energy conservation. By the replacement of the majority of water of large specific heat with a gas (such as air) of small specific heat, the water saving and the great reduction of energy necessary for the temperature rise and heat insulation can be expected especially in the high temperature processing.In this research, it paid attention to the point that liquid flow extremely effective to the washing action and the dyeing is generated in the Plateau border, in the foam or composed by the contact part of foam film and the substrate, positively moving the bubble. Therefore, the velocity measurement system of this liquid flow was constructed. According to the previous research, the foam film was generated by the gas (air) injection to the surface-active agent solution in the flask. The bubble or film generated here was led to the cell for the observation, set on the s … More tage of the microscope, by the glass tube etc. The high-speed video camera was set up in this microscope device, and the observation of a high-speed liquid flow, extremely difficult under a usual condition, was enabled. The bubble after the observation was induced to the trap by the glass tube etc., and was broken.Moreover, the condition setting for the liquid flow observation and the flow velocity measurement was done. The observation target was the transparent colorlessness foam film basically formed with the surface-active agent solution, and the movement of the minute solid polystyrene particle polystyrene etc. as detector was assumed to analyze considering the liquid flow.The liquid flow that had a faster speed than the passing speed of the foam film was admitted in the Plateau border as a result of the observation and the direction was necessarily confirmed it was not constant but so-called turbulent flow was generated. In addition, when the speed element was divided into two directions (right angle with the foam film, and the parallel), the parallel element was the larger. It became clear that the liquid flow along the direction of length of the Plateau border was more active. Less
