Description

利用射流技术的海水淡化处理系统
技术领域
本发明涉及海水淡化处理装置，具体涉及一种利用射流技术的海水淡化处理系统，属于国际专利分类C02F1/00“水、废水、污水的处理”技术领域。
背景技术
目前，国内外采用的海水淡化的方法比较多，如变相法、蒸发法、蒸馏法、冷却法、膜分离法、反渗透法、电渗析法、化学平衡法、离子交换法、水合法、溶剂萃取法等。目前处于领先地位的是闪急蒸馏法，约占当今海水淡化总产量的70％。其缺点是：设备投资多，海水循环量大，制水量小，制水速度慢，浓缩率较低，操作费用高。
发明内容
本发明的目的，在于克服上述方法的不足，提供一种采用射流技术的新型海水淡化处理系统。
本发明的目的是由以下技术方案实现的。
利用射流技术的海水淡化处理系统，包括过滤装置，声能处理装置，淡化装置三部分组成。过滤装置包括海水采集口，连接海水泵，连接粗过滤装置，再连接精过滤装置。精滤后的海水进入声能处理装置，根据实际需要，该声能处理装置可以为二级至多级。经声能处理装置处理过的海水，已成为小分子团海水，储存在储水池中，经泵送至反渗透膜，渗透后的水，成为淡水，储存在淡水池中。
本发明的另一种方案是：将上述方案中的反渗透膜改为蒸馏器，经蒸馏器蒸馏出的淡水，储存在淡水池中。
所述的声能处理装置主要为一流体声能发生器，是一金属腔体，包括一中腔体及上、下轴腔所组成；上、下轴腔的上、下两端面的轴心设有同轴的两个出口，中腔体上均匀分布有入口。中腔体上分布的入口为4-40个。该入口为顺流体走向的斜孔，该入口轴线与外圆切线的夹角为30°-90°。该入口孔径与出口孔径的比值为100∶1-20。所述的流体声能发生器内腔上轴腔的根直径与中腔体的直径之比为1∶1-5。
本发明的优点在于：结构简单，设备投资少，成本低，性能稳定。不仅将海水淡化，而且还将海水短链为小分子团水，易于人体的吸收利用。
附图说明
图1为本发明海水淡化处理系统的装备组合示意图；
图2、3为声能处理装置中声能发生器的内腔结构示意图。
图中：1、海水采集口，2、海水泵，3、粗滤装置，4、精滤装置，5、空压机，6、声能处理装置，7、小分子海水储水池，8、泵，9、反渗透膜，10、淡水池，11、流体声能发生器.
具体实施方式
如图1所示，准备淡化的海水，通过海水采集口1，由海水泵2送至粗滤装置3，进行初步过滤，滤除多种杂质。粗滤后，进入精滤装置4，进行灭菌等处理。精滤后进入声能处理装置6，由空压机5送空气至流体声能发生器11，经二级(可多级)射流振动处理，成为精制的小分子海水，存入小分子海水储水池7中，再经泵8送至反渗透膜9，经反渗透处理后，去除盐分，成为淡水，存入淡水池10内，可供使用。(上述粗滤装置和精滤装置均为现有技术中应用的装置。)
如图2所示，流体声能发生器1为一金属腔体，包括一中腔体及上、下轴腔所组成；上、下轴腔的上、下两端面的轴心设有同轴的两个出口，中腔体上均匀分布有入口。中腔体上分布的入口为440个。该入口为顺流体走向的斜孔，该入口轴线与外圆切线的夹角为30°-90°。入口孔径与出口孔径的比值为100∶1-20。所述的流体声能发生器1内腔上轴腔的根直径与中腔体的直径之比为1∶1-5。发生器的频率为100HZ-30万HZ，发生器的声强大于100dB。液体压力泵的压力为0.2Mpa-80Mpa；液体压力泵的功率为2KW-500KW。
本发明所称的射流技术，即流体声能加工技术，其原理如下：流体声能加工的过程可以简述为：根据对固态、液态、气态等不同的被加工物质的不同特性和加工目的，选择特定的流体动力介质、特定的声频、特定的声强、特定的声场分布和其它工艺条件，在这些条件下对被加工物质进行声能加工处理，使被加工物质发生相应的力学效应、或热学效应、或化学效应、或生物效应、或以上多种效应所引起的变化，达到声能加工的目的。
“流体动力式声能发生器是以流体为动力源，利用调整液体或高速气体来产生可听声与超声的发生器。……的独特优点是结构简单、造价低、处理量大，操作方便，经久耐用，⑦”并且更重要的是它的“耗能小，动力源方便，因而很适合于工业应用。⑧”虽然理论上流体动力式声能发声器具有上述7种优点，但要研制出如本发明的流体动力式声能水煤浆制备系统必须跨越从理论的可能性达到技术现实性之间的距离。
“目前流体动力式声能发声器在工业应用方面已显示出它的独特优点，展示出它的巨大生命力。然而，由于…其中涉及到的数学处理非常困难，因而至今…发声机理还没有得到较为令人满意的解释，大部分的研究仅限于有关实验现象分析。在一系列的应用中，主要基于经验公式以及具体不同的状况的实验曲线给出的结果与特征趋势来考虑问题。对于实际要求来说，理论上的精确预示与计算有关的声波特征，如频率、强度、声场分布等等，无疑能更有利于它的应用以及控制。因而，对流体动力发声器声波的产生和特征的进一步研究是今后值得深入探讨的研究方向。⑨”
