补充资料:浮阀塔
分子式:
CAS号:

性质:一种板式塔,用于气液传质过程中。浮阀的阀片可以浮动,随着气体负荷的变化而调节其开启度,因此,浮阀塔的操作弹性大,特别是在低负荷时,仍能保持正常操作。浮阀塔由于气液接触状态良好,雾沫夹带量小(因气体水平吹出之故),塔板效率较高,生产能力较大。塔结构简单,制造费用便宜,并能适应常用的物料状况,是化工、炼油行业中使用最广泛的塔型之一。在分离稳定同位素时采用在克服泡罩塔缺陷的基础上发展起鼓泡式接触装置。浮阀塔有活动泡罩、圆盘浮阀、重盘浮阀和条形浮阀四种形式。浮阀主要有V型和T型两种,特点是:生产能力比泡罩塔约大20%~40%;气体两个极限负荷比为5~6,操作弹性大;板效率比泡罩塔高10%~15%;雾沫夹带少,液面梯度小;结构难于泡罩塔与筛板塔之间;对物料的适应性较好等,通量大、放大效应小,常用于初浓段的重水生产过程。
