Research of Nanoparticles Aerosol Diffusion through Ceramic Porous Medium

The internal ring matrix distribution of many special ceramic porous medium tubes on a circular plate constitutes an adsorbent device, which can retain nanoparticles aerosol agglomerate by the way of collision, adsorption and diffusion in the process of mass transfer. In this paper, the behavior of industrial flue dust diffusion in the ceramic porous medium device is researched by computational fluid dynamics (CFD) simulation and experiments. Furthermore, resistance characteristic of aerosol flow, nonlinear time-dependent characteristic of flow field and frequency distribution of escaping dust particles are studied. According to the results of simulation and experiment, the lower inlet velocity can keep the lower pressure drop and obtain higher purification efficiency.
