An anti-clogging perforated plate atomizer is designed for high temperature and salinity applications in a novel solar-powered zero liquid discharge humidification-dehumidification desalination system (US Patent Application US62882953). This paper presents a detailed discussion on its design, and operation. Experiments are performed on seven atomizers to study the effect of design, and operating parameters on spray cone angle, and average droplet diameter. Spray cone angle remains constant with change in air mass flux, and increases with increasing orifice diameter, and manifold diameter. It also increases initially with water mass flow rate, and manifold height, before attaining a constant value. Average droplet diameter increases with increasing water mass flow rate, and decreasing air mass flux, orifice diameter, and manifold diameter. Further, anti-clogging performance of the atomizer is tested with hypersaline water of 100,000 ppm total dissolved solid (NaCl) at elevated temperatures such as air at 175 °C and saline water at 45 °C. Results show no clogging for 2–13 h of operation. Near-complete suppression of atomizer clogging makes our new additively-manufactured perforated plate atomizer an ideal fit for high salinity, and zero liquid discharge humidification-dehumidification desalination systems. Additionally, its open-surface design allows additional surface modifications to further reduce clogging, and enhance self-cleaning characteristics.

防堵塞穿孔板雾化器设计用于新型太阳能零液体排放加湿-除湿脱盐系统中的高温和盐度应用（美国专利申请US62882953）。本文详细讨论了其设计和操作。对七个雾化器进行了实验，以研究设计和操作参数对喷雾锥角和平均液滴直径的影响。喷雾锥角随着空气质量流量的变化保持不变，并随着孔口直径和歧管直径的增加而增加。在达到恒定值之前，它最初也随着水质量流量和歧管高度而增加。平均液滴直径随着水质量流量的增加和空气质量通量、孔口直径和歧管直径的减小而增加。更多，雾化器的抗堵塞性能在高温下使用 100,000 ppm 总溶解固体 (NaCl) 的超盐水进行测试，例如 175 °C 的空气和 45 °C 的盐水。结果显示在 2-13 小时的操作中没有堵塞。几乎完全抑制雾化器堵塞使我们的新型增材制造穿孔板雾化器非常适合高盐度和零液体排放的加湿-除湿脱盐系统。此外，其开放式表面设计允许额外的表面修饰，以进一步减少堵塞，并增强自清洁特性。几乎完全抑制雾化器堵塞使我们的新型增材制造穿孔板雾化器非常适合高盐度和零液体排放的加湿-除湿脱盐系统。此外，其开放式表面设计允许额外的表面修饰，以进一步减少堵塞，并增强自清洁特性。几乎完全抑制雾化器堵塞使我们的新型增材制造穿孔板雾化器非常适合高盐度和零液体排放的加湿-除湿脱盐系统。此外，其开放式表面设计允许额外的表面修饰，以进一步减少堵塞，并增强自清洁特性。
