纤维球过滤器布流系统优化及过滤性能研究
Study on distribution system optimization and filtration performance of fiber ball filter
摘要
Abstract
In order to optimize the structural parameters of the industrial filter flow system and improve its filtration performance,the porous media model was used to analyze the filtration performance of the fiber ball filter,and the influence of the structural parameters of the flow system on the filtration behavior was analyzed,and experimental verification was carried out.The results are as follows:for the filter with diameter of 1.5 m and axial diameter ratio of about 1,the optimized outlet diameter is 15～20 mm and the number of outlet is 10～12,the filtration performance is improved about 25％.When the pressure drop of filter material reaches 15 000 Pa,the filtration rate and effluent quality do not meet the production requirements,and the filter material layer needs to be backwashed.The more uniform the distribution of filter bed pollution,the smaller the difference of filter bed radial filtration resistance,the better the"sealing"of filter bed,and the more stable the filter operation.关键词
