一种浮动式搅拌技术

摘要

综述了搅拌对厌氧消化过程的影响.通过比较,分析目前沼气工程中应用的3种机械搅拌方式,针对秸秆厌氧消化过程中易发生布料不均匀、挂壁、结壳等造成消化率低、容积产气率低、使用寿命短的问题,开发了一种能够适应浮动物料、实现垂直空间大范围搅拌的搅拌技术,介绍了其工作原理并展望了在沼气工程中的应用前景.%The impact of stirring on anaerobic digestion process was discussed in this paper. Through the comparison, analysised three kinds of mechanical stirring methods which used in current biogas plans. According to the problems such as low digestibility value, low volumetric biogas production rate and short life performance resulting from uneven distributed material, wall sticking and encrustation, a stirring technology of floating type which can adapt to floating raw materials and realize vertical large-area stirring has been developed. The working principle of this technology was introduced, and its application prospects in biogas plans were proposed.
