| 英文摘要 | A gas-liquid cross-flow array (GLCA) system is proposed as the direct condensing technique for PM2.5 and moisture simultaneous removal from the wet flue gas. Such a GLCA with huge surface area is formed by numerous vertically down-flowing wastewater films along a number of wires through a perforated distributor. And each falling film acts as an independent sink to remove PM2.5 and moisture. Analytical models are developed to predict PM2.5 and moisture removal efficiency of a GLCA, based on the differential equation of convection diffusion with diffusiophoresis (DP), the only considering mechanism of PM2.5 removal. The models indicate that PM2.5 removal efficiency is proportional to the moisture removal amount, and PM2.5 removal efficiency can be increased sharply due to moisture condensation. Experiments with a lab-scale GLCA are carried out with variable humidity of inlet gas, and a constant gas (60 degrees C) and water (20 degrees C) temperature. The experimental measurements for PM2.5 and moisture removal generally compare satisfactorily with the model predictions. (C) 2020 Institution of Chemical Engineers. Published by Elsevier B.V.
