开口散射器对滤筒除尘脉冲清灰效果的影响
Influence of opening diffuser on pulse-jet dust-cleaning efficiency of cartridge filters
摘要
Abstract
Self-designed conical diffuser with hole or ring opening was used in pulse-jet dust cleaning system in order to uniformize the static peak pressure on side surface of filter cartridge during cleaning.It leads to good cleaning efficiency in top part of cartridge same as in bottom part.Analyses dust cleaning flow field with method of numerical simulation, it turns out that the surface dust cleaning uniformity along axis of filter cartridge in using conical diffuser with hole is better than without hole.As the hole increases bigger and induced air more, however, the static pressure tends to be nonuniform from top to bottom of filter cartridge.It is found that within the size range in this study, the cleaning uniformity is the best when the diameter of hole reached 22.5 mm.关键词
