纳米与微米颗粒污垢沉积的表面特性及等效关系
Nanoparticles and microparticles fouling surface characteristics and their equivalent relationship
摘要
Abstract
Particulate fouling research is mainly done by experiment at present. There are hardly any research on internal relationship between nanometer and micrometer particles fouling through simulation and experiment. There are some similar deposition characteristics between nanoparticle and micro particle fouling. Nanoparticle and micro particle fouling deposition experiments were conducted under different working conditions,and surface characteristics were observed by SEM. The fouling deposition quantity was determined by simulation with different particle sizes. A gradual growth trend of deposition quantity of particles fouling was observed. Due to agglomeration effect,there was similar deposition result between nanoparticles and micro particles fouling. The equivalent diameter was proposed for nanoparticles by combining the nanoparticles experiment and micro particles simulation results. The equivalent diameter was 9.2μm for 0.4g/L nanometer suspensions. The equivalent diameter was 11.2μm for 0.6g/L nanometer suspensions.关键词
