项目简介:研究苏尔寿、天大等公司液体分布器的设计准则,将其应用到公司的设计中。随着空分设备向大型及特大型化发展,特别是八万等级以上的特大型空分项目,精馏塔直径的增加与精馏塔运输尺寸的限制之间的矛盾日益突出。在大型、特大型空分系统中,普遍采用新型高通量填料。而高通量填料在精馏塔中的应用导致精馏塔横截面单位面积上的气体、液体通量增大,气相动能因子以及液体喷淋密度将超出常规液体分布器的设计范围,同时随着精馏塔直径的增加,对液体分布的均匀性也提出了很高的要 Project Description: Study Sulzer, Tianda, and other liquid distributor design guidelines, its application to the company’s design. With the development of large-scale and oversize air separation plants, especially the large-scale air separation project with a size of more than 80,000, the contradiction between the increase of the diameter of the rectifying tower and the restriction of the size of the rectification tower has become increasingly prominent. In large, very large air separation systems, the widespread use of new high-throughput packing. The application of high-throughput packing in the rectification column results in the increase of the gas and liquid flux per unit area of ​​the cross-section of the rectification column. The kinetic energy factor of the gas phase and the liquid spray density will exceed the design range of the conventional liquid distributor. Meanwhile, With the increase of the diameter of the rectification column, the uniformity of the liquid distribution is also proposed to be high
