Research of ceramic membrane filtration characteristics in continuous reaction system

陶瓷膜组件具有较高的分离效率且稳定性好,本文是将多相反应器与陶瓷膜过滤组件组成连续装置,以期实现液固分离和操作的连续化,以空气-水-活性炭三相为研究介质,对其过滤特性进行研究,结果表明:陶瓷膜组件能够确保在较长时间内过滤的稳定性;过滤通量受过滤压力的影响较大,过滤压力越大过滤通量越大;过滤通量随着循环流量的增大而增大。

Ceramic membrane module has high separation efficiency and good stability. In this thesis, we make multiphase reactor and ceramic membrane filtration components a continuous device, in order to realize the solid-liquid separation and continuous operation, we used three phases system including air, water and activated carbon as our study medium, studying its filtration characteristics, investigating the stability of the ceramic membrane filter components and membrane filtrating pressure and the effect of circulation pump frequency conversion on the components of ceramic membrane filtration flux. The results showed that the ceramic membrane components can ensure the stability to filter in the longer term;Filtration flux are greatly affected by the filtration pressure proportionally, the greater the filtrating pressure, the larger the filtration flux will be; In addition to this, the filtration flux increases with the growth of circulation flow rate.
