无机陶瓷膜提纯凹凸棒石粘土的工艺
Study on Purification of Attapulgite with Inorganic Ceramics Membranes
摘要
Abstract
The microfiltration separation process of attapulgite clay was studied with inorganic ceramic membrane. The influence of operation parameters, including membrane pore size, operation condition (pressure and temperature) , and the solution properties of the permeation flux and retention rate were studied respectively. The results showed that permeation flux and retention rate were different for different membrane pore size. The permeation flux was 48. 5 L/ (m2· h) and retention rate was above 99% when the pore size of membrane was 0. 2p.m. The optimum parameters obtained include operating pressure 0. 12MPa, operating temperature 323 K, cross —flow velocity flux 1. Om/s, mass concentration of the suspension 20g /L and pH 6. 0.关键词
