摘　　要：在保持塔体不动的情况下,采用DJ-5型塔板(新型固定阀悬挂式降液管塔板)一代一更换燕化乙烯装置丙烯精馏塔原斜孔塔板。在保证塔顶丙烯产品摩尔分数大于99.6%的前提下,塔釜丙烯损失由摩尔分数42.69%降至7.67%,并提高了处理能力。改造结果表明,DJ-5型塔板具有分离效率高和处理能力大的优点。In the case of utilizing original tower,DJ-5 trays （new fixed valve rectangular suspending downcomer directing tray） are used to replace the slant-hole trays of C3 splitter one by one in the ethylene plant in Yanshan.After revamping,the capacity is increased.In the premise of above 99.6％ of the propylene mole purity,the propylene loss from bottom of column is reduced from 42.69％ to 7.67％.The result of revamping shows that DJ-5 tray has characteristics of high separation efficiency and large capacity.
