高效高速波型挡板塔盘在化工生产上应用

阐述波型挡板塔盘气液两相接触流动，传热，传质的机理分析，该塔盘用于分离甲醇－水物系的甲醇回收等，已在全国８个化工厂推广应用了３１套塔装置，实践表明其生产能力大，可提高３０％－１００％；分离效果好，塔顶，塔釜液的质量控制指标为０．１％或０．０１％以下，回流比可减少３０％－５０％；弹性大，压降小，不易堵塔，操作稳定易调节控制；节能降耗，经济效益显著，可在化工，石油化工等的精馏，吸收，洗涤除尘冷却等单元

A Wave shaped Baffle Trays of High Effiency and High Capacity and Its Application to the Production in Chemical Industry

An analysis is made on the vapor liquid flow and the heat mass transfer of the wave shaped baffle trays, with emphasis on the mechanism. Thirty one sets of this baffle trays have been applied in eight chemical plants all over the country for separating methanol water mixture which leads to recovering of methanol. The practive shows its high efficiency and high capacity. It has led to 30% 100% increase of productivity; it shows a good separation, a quality control index of liquid at tower top and tower bottom approaching 0.1% or below 0.01%, and a reflux rate of 30% 50% decrease; it shows a high elasticity and a small pressure drop, it will not lead to tower stoppage, it is stable in operation, and it is easy of adjustment and control; it saves energy and raw materials and it has a significant economic benefit. It can be popularized and applied to such units as distillation, absorption, washing, dusting and colling in chemical and petrochemical engineering.
