摘要:为了探究进气流量和相对湿度对活性炭吸附法和光催化转化法动态净化室内空气中总挥发性有机物（TVOC）的影响，设计了一套包含活性炭吸附器和光催化反应器的多功能空气动态净化实验装置，并利用该装置进行了室内空气净化实验。通过设置不同进气条件（进气流量和相对湿度）对室内空气进行净化实验，采用气相色谱仪对样品TVOC浓度进行检测，并与未经净化处理的空气样品进行对比，计算TVOC去除率。结果表明：该实验装置能够实现连续进气且能对进气流量和相对湿度进行精准调节；随着进气流量增大，活性炭和光催化对TVOC去除率减小；随着进气相对湿度增大，活性炭对TVOC去除率减小，光催化对TVOC的去除率呈现先增大后减小的趋势。以上实验结果为气候舱空气净化系统、家用空气净化器及室内新风过滤系统等动态空气净化系统的设计提供了参考。

Abstract:In order to determine the effect of inlet flow rate and relative humidity on activated carbon and photo catalytic purification of total volatile organic compounds (TVOC) in indoor air in dynamic purification process, a set of multi-functional air purifying experimental device including activated carbon adsorption tank and photo catalysis reactor was designed and used to conduct indoor air purifying experiment. Experiments were performed in a thermostatic laboratory with different inlet flow rates and relative humidity, respectively. The gas chromatograph was used to detect the concentration of TVOC in the air samples under different air inlet conditions and compared with the air samples without the air purification treatment to calculate the TVOC removal rate. Experimental results show that the experimental device enables continuous air intake and accurate adjustment of intake air flow and relative humidity. The removal rate of TVOC by activated carbon and photo catalyst decreases when the flow rate increases. When the relative humidity of intake air increases, the removal rate of TVOC by activated carbon decreases and the removal rate of TVOC by photo catalysis first increases and then decreases. The above results provide reference for the design of dynamic air purification system such as climate chamber air purification system, home air purifier and indoor fresh air filtration system.
