污泥焦浆的表面特性及对成浆特性的影响
Surface Properties of Sludge-petroleum Coke-Slurry and Its Effect on Slurryability
摘要
Abstract
The experimental study of the slurryability of municipal sludge and petroleum coke was done with the anion surface active agent methylene naphthalene sulfonate-sodium styrene sulfonate-cacodylic acid sodium salt as dispersant, investigating the internal relationship of surface properties of sludge-petroleum coke-slurry and the slurryabilTty. The results show that surface tension of the slurry increases and the slurryability decreases with sludge add ratio increasing. At the same time, zeta potential absolute value and particle surface charge increase and the stability enhances with sludge add ratio increasing. The petroleum coke water slurry becomes pseudoplastic fluid from dilatant fluid by adding sludge, and the pseudoplastic characteristics increase with sludge add ratio increasing. When the sludge is modified with NaOH or CaO, the surface tension and zeta potential absolute value decrease slightly, and the slurryability enhances, and the stability decreases, and the pseudoplastic characteristics weaken. The modification effect of CaO is much more obvious than that of NaOH. The pseudoplasticity of slurry is negatively associated with the slurryability and is positively associated with the stability.关键词
