一种基于半导体制冷的亚沸蒸馏水器
本专利技术涉及一种蒸馏水装置,具体为一种利用半导体制冷技术,不需冷凝水、节能型的蒸馏水装置。
技术介绍
蒸馏水是各类科研院所、高校、医院、药企等单位应用最广泛的溶剂,需求量极大。最经典的蒸馏水器是利用电能将水加热沸腾成为蒸汽,再利用玻璃或石英冷凝管将水蒸气冷却为水,这一过程可以除去水中大部分的离子及固体颗粒。若要求严格,还可进行二次或三次蒸馏,制得纯度更高的蒸馏水。这一方法较为简单,但存在的问题也是显而易见的。首先,这种方式能耗巨大。水的比热容极大,将水加热至沸腾所需电能消耗也极为巨大,并且这部分热量最终仍要被冷凝水带走才能使水蒸汽冷却。其次,为了加快制水速度,通常都要将水加热至沸腾,大量气泡冒出时有可能将水中的不挥发性杂质带入水蒸气,导致所得蒸馏水纯度降低。第三,这种方式需要消耗大量的冷凝水。以实验室常用的每小时生产1.6升的玻璃蒸馏水器为例,每制备1升蒸馏水至少消耗80升自来水。利用循环水泵将冷凝水循环利用,虽然可以节约水资源,但使用一段时间后冷凝水温度升高,则必须停止使用,待冷凝水自然降至室温再使用,极为不便。另外,由于我国自来水普遍硬度较高,水蒸发后残留水垢的清洗也给仪器的使用带来了很多不便。为了解决这些问题,许多新颖的蒸馏水器被设计出来。例如市面上出售的石英亚沸蒸馏水器,是将电加热管置于水面以上而不是水中。加热管与水的本体并无直接接触,因此只能使水的表面处于亚沸状态,水蒸气带出的杂质显著减少。虽然这种方式制水速度降低了,但蒸馏水的纯度却提高了。然而,市售的亚沸蒸馏水器的加热管与冷凝管距离很近,电热管产生的热量大部 ...
