This work is focused on an in-depth experimental characterization of multi-tube reactors for indoor air purification integrated in ventilation systems. Glass tubes were selected as an excellent photocatalyst substrate to meet the challenging requirements of the operating conditions in a ventilation system in which high flow rates are typical. Glass tubes show a low-pressure drop which reduces the energy demand of the ventilator, and additionally, they provide a large exposed surface area to allow interaction between indoor air contaminants and the photocatalyst. Furthermore, the performance of a range of P25-loaded sol-gel coatings was investigated, based on their adhesion properties and photocatalytic activities. Moreover, the UV light transmission and photocatalytic reactor performance under various operating conditions were studied. These results provide vital insights for the further development and scaling up of multi-tube reactors in ventilation systems which can provide a better comfort, improved air quality in indoor environments, and reduced human exposure to harmful pollutants.
本工作重点研究集成在通风系统中的用于室内空气净化的多管式反应器的深入实验特性。选择玻璃管作为优秀的光催化剂基底，以满足通风系统中操作条件苛刻的要求，通风系统中的典型特征是高流速。玻璃管的压降低，降低了通风机的能源需求，此外，它们提供了较大的暴露表面积，允许室内空气污染物与光催化剂之间相互作用。此外，还研究了一系列负载 P25 的溶胶-凝胶涂层的性能，基于其附着力和光催化活性。此外，还研究了在各种操作条件下的紫外光透过率和光催化反应器性能。这些结果为在通风系统中进一步开发和放大多管式反应器提供了重要的见解，这可以提供更好的舒适度，改善室内环境的空气质量，并减少人类对有害污染物的暴露。
