摘要
为解决日益恶化的全球淡水危机及干旱环境中紧急用水等问题,将具有灵活表面化学性质、低渗水率和高导电性等特性的聚二甲基硅氧烷(PDMS)技术应用到空气取水装置中,设计了一种基于PDMS的微型空气取水装置。开展了该微型空气取水装置的结构与工作原理的研究,建立了微型空气取水装置的有限元流场分析模型,进而对空气取水装置的取水效率进行了仿真。利用PI电热膜加热对空气取水装置的取水效果进行了测试。实验结果表明,所制作的空气取水装置在10 min的解吸附时间内可以产水0.2 ml,能够从常温常压的空气中取水,验证了该微型空气取水装置的可行性。
In order to solve the problems of global fresh water crisis and getting water from dry surroundings, the technology of polydimethyl- siloxane （PDMS）, a kind of material with certain facial chemical properties, low water permeability, high electrical conductivity and other physical and chemical properties was applied to design a diminutive microfluidic atmospheric water generator which is mainly made of PDMS. Researches about the structure and the working principle of the atmospheric water generator was promoted, the finite element analysis model to simulate the fluid field of the producing process as well as the productivity of the device was built. The performance of the water generator was tested using the PI electric heating film. The experimental results indicate that the device fabricated is able to produce 0.2 ml water in ten minutes during the desorption period, capable of getting water from the air in normal temperature and pressure. Thus the feasibility of the micro atmospheric water generator is verified.
