Abstract In this study, we propose a new design for a microchannel filter. The closed indoor environments with which we interact daily are sources of diseases for the respiratory system of human beings. Recommendations for the design of microchannel filters for indoor air purification are proposed, implementing low-cost microequipment technology (MET) for the manufacture of the elements that constitute a microfiltration system. For the microchannel filter production, we proposed to use MET, which is a miniaturization technology and can reduce manufacturing costs. The microchannel filter was 3.75 cm in radius with a thickness of 3 mm. It had a triangular profile and a helical trajectory. It was designed, manufactured, and tested for two profile dimensions. The main purpose was to reduce the pressure drop of the air flow through the filter. We described the air flow simulation for the microchannel filter using SolidWorks. A prototype microchannel filter was constructed, which underwent manufacturing tests. It is possible to clean the microchannel using water flow, which allows us to maintain the filtration quality within an optimum range of contaminant removal.

用于空气净化的微通道过滤器

摘要 在这项研究中，我们提出了一种新的微通道过滤器设计。我们每天接触的封闭的室内环境是人类呼吸系统疾病的来源。提出了用于室内空气净化的微通道过滤器设计的建议，采用低成本微设备技术 (MET) 来制造构成微过滤系统的元件。对于微通道过滤器的生产，我们建议使用MET，这是一种小型化技术，可以降低制造成本。微通道过滤器的半径为 3.75 厘米，厚度为 3 毫米。它具有三角形轮廓和螺旋轨迹。它是针对两个轮廓尺寸进行设计、制造和测试的。主要目的是减少通过过滤器的气流的压降。我们使用 SolidWorks 描述了微通道过滤器的气流模拟。构建了原型微通道过滤器，并进行了制造测试。可以使用水流清洁微通道，这使我们能够将过滤质量保持在最佳的污染物去除范围内。
