With the processing of evaporation and the increase of the liquid concentration,the periphery of film dropping tube cannot wetted sufficiently,thus,the use of double tube sides is necessary.
随着蒸发的进行,料液浓度的增高,降膜管周边润湿量不足需要分程,即双管程(或多管程)进料,液体分布器在本效中不能按常规的结构进行设计,否则布料不均,降膜管底端结焦严重,产品质量会受到影响,清洗也困难,加密分布器上小孔,能够消除结焦,此方法经过应用效果良好。
