摘要:
针对节水增氧灌溉的设备存在气泡在水中溶解度较低、占地面积大、现有的微气泡释放器不能方便与现有微灌系统进行集成的问题,研究基于微纳米气泡的增氧灌溉技术与设备。设计微纳米气泡释放器的结构,对结构参数进行计算及优化,确定释放器最佳结构参数的组合:喉部孔直径为3mm,湍流腔厚度为2mm,出口角度为6°,出口个数为2个。在释放器计算仿真基础上,完成微纳米气泡发生装置试验平台搭建,研制增氧灌溉装置并开展示范应用,该装置具有增氧效率高、体积小、释放器可直接安装在灌溉管路上等优点,在节水灌溉领域有着较为广阔的应用前景。
Abstract:
The current oxygen-enhanced irrigation equipment has the problems of low bubble solubility, large volume, and the existing micro-bubble releaser cannot be easily integrated with the existing micro-irrigation system. This paper develops aeration and aerated irrigation equipment based on micro-nanometer bubbles. Structural parameters of releaser are optimized using fluent software under the evaluation indicators such as the internal negative pressure cloud diagram, the turbulence intensity cloud diagram, and the flow rate of the releaser. Orthogonal experiment was opened on the basis of single factors and the best structural parameters of the releaser were determined as follows:throat diameter 3 mm, turbulence chamber thickness 2 mm, exit angle 6 degrees, and outlet number 2. Based on the release simulator simulation, the micro-nano bubble generating device test platform was built, and the aerated irrigation device based on micro-nanometer air bubbles is completed. The device has the advantages of high oxygenation efficiency, small size, and the release device can be directly installed on the irrigation pipeline, and which has a wide application prospect in the field of irrigation.
