摘要

该文开发了一套利用菲涅尔透镜聚焦太阳光加热钻杆从土壤中取水的装置,在证明可行性后对其进行优化,可提高钻杆高温区域温度并增强钻杆的透水性,研究土壤含水率和钻杆透水性对取水能力的影响。结果显示,在含水率27.5%、太阳光斑功率为152 W的条件下,优化后的装置每小时取水量可达45 g。该装置可在不投入外界其他形式能量的前提下仅靠太阳光运行,其能量利用效率高达20.41%。

Abstract

This research develops a device that uses a Fresnel lens to focus sunlight to heat a porous media drill pipe to extract water from the soil. After proving the feasibility, the device is optimized to increase the temperature of the high-temperature area of the drill pipe and strengthen the drill pipe water permeability, and studies the effect of soil moisture content and drill pipe water permeability on water extraction capacity. The results show that under the condition of 27.5% moisture content and 152 W solar spot power, the optimized device can take 45 g of water per hour. The experimental device can operate solely on sunlight without inputting other forms of external energy, and its energy utilization efficiency is as high as 20.41%.
