利用CFD方法优化红泥沼气池发酵罐内流场形态的研究综述
时间 : 2019-06-18 浏览量 : 24

沼气是当今世界最具希望的可再生能源方式,兼具强大的环保和能源效益3),尤其善于处理数量巨大的有机废水。搅拌可以提升沼气厌氧发酵的效率,显著提升产气率和污染物去除率,现代沼气工程彩经网普遍都要添加搅拌工艺来提高发酵效率。然而从当前的工程实践来看,大量工程采用了粗劣的搅拌工艺,对发酵效率的提升收效甚微,甚至消耗更多的能源8。造成这种现象的根源在于


沼气厌氧红泥膜沼气池发酵罐必须严格厌氧封闭,人们无法对其内部流场进行准确的分析测试,于是设计人员在不掌握流场形态的情况下,随意添加了一些搅拌措施,但实际流场形态很差,并不适用于其罐体形状和原料特性9。

但现在计算机数值模拟方法可以在很大程度上解决这个问题,沼气红泥膜彩经网沼气池发酵料液的搅拌本质上是在外  力作用下的流动过程,数值模拟计算可以帮助人们
