Description

制备蒸馏水的装置
本申请要求2015年12月17日提交中国专利局、申请号为201510956802.4、发明名称为“制备蒸馏水的装置”的发明专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本发明属于蒸馏水制备领域，具体涉及一种制备蒸馏水的装置。
背景技术
目前市场上蒸馏水的制备方法大多采取电加热使水沸腾，然后冷凝水蒸汽取水的方法。这种传统的方法的主要缺点是高能耗，低产量。
发明内容
本发明的目的是提供一种低能耗的制备蒸馏水的装置。
为实现上述目的，本发明提供了以下技术方案：一种制备蒸馏水的装置，包括用于盛放原料水的取液罐和用于收集蒸馏水的蒸馏水罐，所述取液罐和蒸馏水罐之间通过管道连通，且该管道上设有用于将取液罐中的气体抽送至蒸馏水罐的抽排装置，所述取液罐和蒸馏水罐上还设有与抽真空装置连通的抽气阀门，抽真空装置对取液罐和蒸馏水罐抽真空，使两罐保持相同的负压状态。
本发明的技术效果在于：采用抽真空的方式将水的沸点降低，使其在常温下沸腾，以达到饱和蒸汽压的状态，根据饱和蒸汽压的基本定义(即在密闭空间内的液体在饱和蒸汽压的状态下，其液体物质在气相与液相的界面上的气化速度与液化速度处于动态平衡状态)，若将取液罐中的水蒸气不断输送至蒸馏水罐，取液罐中的气体分子密度减小，则取液罐中的液态水会加速蒸发，以补充流失的气相分子，由此能够使取液罐中的液态水不断蒸发，而水蒸气进入蒸馏水罐后，由于气相分子密度增大，因此水蒸气会加速液化变为蒸馏水，本装置摒弃了以往电加热制备蒸馏水的方式，采用低压蒸馏的方式，大大提高了能源利用率，降低了能耗。
附图说明
图1是本发明实施例1的原理图；
图2是本发明实施例2的原理图；
图3是本发明实施例3的原理图；
图4是本发明中抽排装置的另一实施例结构示意图。
具体实施方式
本发明所依据的理论基础：
通常，在高原上，水在不到一百度就沸腾了。海拔越高，沸点越低。这是因为水的沸点与地球表面的大气压存在着固定的对应关系。如图下表所示：
压力(kPa) 101.41 47.412 38.592 31.198 25.040 19.944 15.7597
沸点(℃) 100 80 75 70 65 60 55
压力(kPa) 12.3499 9.5932 7.3835 5.6278 4.2460 3.1692 2.3388
沸点(℃) 50 45 40 35 30 25 20
当水在一个大气压环境下时(101Kpa)，它的沸点是100℃；当水在高原上只有0.5个大气压环境下时，它的沸点只有80℃；0.0238大气压(2.38Kpa)时水的沸点是20℃。从这里可以看到水的沸点与大气压力的一一对应关系。根据这个对应关系，只要将水的环境气压降到水的环境温度对应的沸点气压，水就能够沸腾。此时的环境气压就是此温度的水的饱和蒸汽压。根据饱和蒸汽压的基本定义，此时，在密闭空间内的液体在饱和蒸汽压的状态下，其液体物质在气相与液相的界面上的气化速度与液化速度处于动态平衡状态。其物理意义是，在温度不变的前提下，密闭空间内气相分子的密度保持不变。其基本性质为，饱和蒸汽压状态下的液体气压值，与其存在的空间大小无关。这就是说，当一个密闭空间内的液体处于饱和蒸汽压的状态时，将它的空间放大或是缩小，其气压值不变。这是因为，在饱和蒸汽压状态下密闭空间内，当空间放大时，为维持空间气相分子密度不变，液体的汽化速度大于液化速度，保持动态平衡。当空间被缩小时，液体的液化速度大于汽化速度，保持动态平衡。以上特点，各版本热力学 著作均有论述。
基于上述理论基础，本发明提供了以下技术方案：
如图1-3所示，一种制备蒸馏水的装置，包括用于盛放原料水的取液罐10和用于收集蒸馏水的蒸馏水罐20，所述取液罐10和蒸馏水罐20之间通过管道11连通，且该管道11上设有用于将取液罐10中的气体抽送至蒸馏水罐20的抽排装置30，所述取液罐10和蒸馏水罐20上还设有与抽真空装置13连通的抽气阀门12，抽真空装置13对取液罐10和蒸馏水罐20抽真空，使两罐保持相同的负压状态。
所述抽排装置30包括一密封壳体31内设置的两同步反向转动且相互啮合的叶轮32，所述密封壳体31上设有进气口33和排气口34，所述进气口33与取液罐10连通，排气口34与蒸馏水罐20连通，所述两叶轮32无论旋转到任何角度，进气口33和排气口34都被两叶轮32分成相互隔离的两个区域。
如图1-3所示，为增加蒸馏水附着面积，提高液化速度，所述蒸馏水罐20内设有不锈钢丝球21。
本发明中抽排装置30的其中一个实施例为：
如图1-3所示，所述叶轮32为一字型结构，所述叶轮32的两端为圆弧面，叶轮32的两侧腰部位置处设有弧形凹槽，两叶轮32在旋转过程中，弧形面与弧形凹槽交替啮合。
本发明中抽排装置30的另一实施例为：
如图4所示，所述叶轮32为三叶片结构，且三个叶片外端均为圆弧状，相邻两叶片之间设有弧形凹槽，两叶轮32在旋转过程中，叶片与弧形凹槽交替啮合。
由于水的气化是吸热过程，因此取液罐10在工作过程中，温度会逐渐降低，为了维持取液罐10的温度，提高蒸馏效率，还可以对取液罐10进行温度补偿，本发明针对温度补偿提供了以下几种实施例：
实施例1
如图1所示，所述取液罐10内设有加热装置14。优选的，所述加热装置14为陶瓷加热片。
除了采用外部加热补偿，本发明还可以在所述蒸馏水罐20和取液罐 10之间设置热传递结构，根据这一思路，本发明提供了以下两种实施例：
实施例2
如图2所示，所述蒸馏水罐20位于取液罐10内部，两者构成夹套式结构。由于水蒸气液化是一个放热过程，因此蒸馏水罐20中的温度会逐渐升高，将蒸馏水罐20放置于取液罐10中，利用蒸馏水罐20的热量对取液罐10进行温度补偿，能够进一步降低能耗。
实施例3
如图3所示，所述抽排装置30与蒸馏水罐20之间的管道上设有一段盘管15，所述盘管15穿插在取液罐10内部。本实施例与实施例2的原理相同，都是利用蒸馏水冷凝时的热量对取液罐20进行温度补偿，以降低能耗。
工作时，首先打开阀门12，将抽真空装置13开启对该装置抽真空，一直抽到取水罐10内的水沸腾，取水罐10的水沸腾后，说明该装置内气压已经达到了饱和蒸汽压。把真空泵管道上二个阀门12关闭。此时，叶轮腔的进气口压力、出气口压力、取水罐压力、蒸馏水罐压力都相等。都是此温度的水的饱和蒸汽压力。然后将二个叶轮32按图示旋转方向等速旋转。于是，进气口33对应空腔内的气体不间断的被取走，也就是前面说的空间被扩大，分子密度降低，取水罐10内汽液界面的汽化速度大于液化速度。一直处于沸腾状态，因而取液罐10内的水也就在不间断的减少。出气口34空腔内的气体不间断的获得，也就是前面说的空间被压缩，分子密度提高，蒸馏水罐20内水的液化速度大于汽化速度，蒸馏水罐20内的水将不间断的增多。此水是取水罐10内沸腾汽化再液化的水，因此它是蒸馏水。
