Description

用于生产饱含空气的水的装置
本发明涉及一种用于生产饱含气体的液体的装置，该装置包括一个压力容器，后者具有压力气体和液体供给装置、用于放出饱含气体的液体的装置和用于把压力容器的液体保持在预定液位的装置。
浮选分离设备被越来愈多地用于净化水，饮水和废水，一直在设法增加水流过净化设备的流量和减小所需罐体和净化设备的尺寸。就饮水来说，对最终产品的要求是大体一致的，净化设备的结构大致取决于水源或来水的性质。在水源是湖水或河水时，通常在过滤室中从水中分离出粗大颗粒，然后，在一絮凝室中加入沉淀剂和絮凝剂对水进行化学和生物净化。通过使颗粒在重力作用下淀积到一沉淀罐的底部，来把沉淀的颗粒从水中分离出来。不同类型的颗粒具有不同的密度，从而具有不同的沉淀速率。为了使低密度颗粒即“轻颗粒”随着水流过沉淀罐而有时间沉淀下来，该罐必须具有很大的面积来提供一段长时间让这类轻颗粒沉淀。
通过浮选分离过程可大大降低颗粒分离时间，在其中加入微观气泡，使水中的颗粒或颗粒絮片粘附着在这些气泡上。这些气泡也有助于形成颗粒絮片及保持絮片聚合。气泡迅速升到水面上，其上携带着粘附的颗粒或颗粒絮片，这些颗粒絮片在水面上形成一层稳定的浮渣，借助于刮除装置或通过间断地升起浮选分离罐中的水位，使浮渣层流进设在罐体一边处的一个浮渣槽道来除去这些浮渣。
用在浮选分离过程中的微观气泡的直径为30-80μm，例如，仅把空气直接注入水中不能产生微观气泡。通常通过把受压气体从压力容器中放入净水之中来生成用于饮水浮选分离过程的微观气泡。为此要设法达到尽可能最高的饱和度。该水通常称为散化水(dispersion water)，被导入一个进口，该进口用于经过絮凝过程的水，称其为絮凝过的水，该入口在浮选分离罐的底部，同时使该水保持高压，在此通过分列的喷嘴或喷头供到絮凝过的水，将该喷嘴做成能够使压力瞬时下降到下述数值，使溶解在水中的空气以微观气泡形式释放，并在水中形成空气迷散。
用于生产最大限度地饱含空气的受压散化水的压力容器通常借助于控制设备和相关的水位传感装置来保持半满着水，进入和流出的水流位于压力容器中的水面之下。压缩空气进入水面上的充气空间，压力容器具有相当大尺寸以获得空气和水之间大面积接触。在另外现有设计中，压力容器的直径减小了，该压力容器通常有一人高，通过一个设在容器侧壁的喷嘴把水供入空气空间来补偿减小的空气/水接触面，通过该喷嘴把水喷射到对面的容器壁上，从而在某种程度上分散了水注。
就水的净化来说，浮选分离法费时少得多，较短的流通时间可使净化设备做得更小而保持着生产能力不变。
这类净化设备的空间要求降低打开新的应用前途。这种发展要求所有的组件具有更小的尺寸，最好也具有更高的性能。这也应用于散化水准备单元，其中再次循环利用已经净化过的水。散化水中空气饱和度的增加则减少使用循环水，由此提高了整个净化设备的效率。
本发明的目的是提供一种用于生产具有高气体饱和度的散化液体的装置。另一个目的是提供兼有高性能和小尺寸的装置。具有权利要求书中所述特征的装置可以达到这些目的。
下面参照本发明的实例和附图来更加详细地描述本发明，附图中：
图1是传统设备的浮选分离分离罐的示意性侧剖视图；及
图2是本发明的散化水生产装置的局部剖视图。
图1是普通装备的浮选分离罐的示意性剖视图，其总体上由标号1表示。该罐包括一个进口2，从一个絮凝室(未示)向该进口供水。利用一个装在进口2内侧的档板3使水在罐1中向上流动。在罐壁4和挡板3之间形成一个袋状区，一排带有喷嘴或喷头5的配水管6开口开在该袋状区之中，图中示出其中一条管。管6的作用是向通过进口2流进罐中的絮凝处理过的水提供饱含空气的水，即散化水，其中高压注射的散化水加速了絮凝处理过的水的运动。把喷嘴5的结构做成使散化水的压力立即下降，从而从散化水中释放出空气并形成微观气泡，在汽泡向水表面运动的过程中，它们收集颗粒和颗粒絮片，并将这些颗粒和絮片的大部分迅速搬运到水面，而在此形成一层浮渣，借助于某种形式的浮渣刮除装置7将其除去并沉积在罐壁9附近的一个浮渣槽道8中，亦可用其他方式去除。不能由微观气泡收集和带到表面上的重颗粒，就被捕获在一个位于挡板3的后侧和罐壁9之间的过滤器10之中，并通过该过滤器将净化或纯化过的水通过一个出口11送往一个纯净水罐(未示)。将一部分纯净水从纯净水罐在高压下送到一个压力容器12的进水口13。在该压力容器中生产散化水，通过一个进气口14从一压缩机(未示)中给压力容器12供应压缩空气，然后将饱含空气的水经一个出口15和配水管6返送给安装在浮选分离罐中的喷嘴5。
图2是用于生产散化水的具有创造性的装置的局部剖示意图。该装置包括一个竖直放置的压力容器21，它包括有市场上可买到的管段并在一进口管22和一出口管23之间具有一个扩大的形状。进口管22通向一个喷淋装置24，它是一个进口管延伸段且在其自由端是封闭着的。延伸管24的外表面上全部钻有细喷孔25，图2中仅示出了其中几个。在运行中，压力容器21是半充满水的，设在容器壁上的两个传感装置26把信号送给控制装置(未示出)，控制装置按需要减小或增加给水，或交替调节压力容器21中的空气压力。压缩空气经管27供给并且由一个安装在管27上的电磁阀28控制。如图2中带有一对断开的箭头，在运行中，水从喷淋装置24喷射到压力容器的内壁上，而使该内壁盖有一层水幕，向该水幕连续不断地供水，从而总是保持水幕具有最大的空气吸收率。
该具有创造性的装置吸收空气的能力是对现有技术的重大改进，使该具有创造性的装置的尺寸比现有技术中显著减小。例如，现有装置的高度几乎达2m，直径35cm；该具有创造性的装置高约1m，直径10cm。
因为尺寸减小，现用的压力容器可用一个4″的管取代，后者装有减小的接头，如1″的进口管和2″的出品管。
应该理解的是该发明也可用于其他的气体和液体装置中，尽管是参照净化水厂中的浮选分离罐来描述本发明的。
