The present invention relates to oil refining equipment, in particular to a dehydrogenation of the condenser, which comprises a shell body, U type tube, shell feeding tube, shell discharging pipe and non condensable gas exhaust pipe; wherein, the shell body consists of a cylindrical main body and both sides expand through a flange which is installed on both ends of the main shell the head; type U tube including T type baffle, tube bundle and back cavity; the shell feeding pipe is arranged on the main shell side of swelling, entered by the main body around the top of the shell, shell to bottom along the wall of the main shell; the shell from the main discharge pipe on the other side of the lower part of the shell swelling into the side. Along the inner wall of the main shell along to the bottom of the main shell; the shell discharging pipe in the main shell is provided with a downward bending part, the bending part is provided to the non condensable gas exhaust pipe; the invention through the specific design of the condenser shell dehydrogenation pipeline structure, using the As the liquid sealing medium, the closed control of the inner shell of the condenser is realized, and the process effect of the equipment is improved.
【技术实现步骤摘要】
脱氢塔顶冷凝器
:本专利技术涉及石油炼化设备,特别涉及一种脱氢塔顶冷凝器。
技术介绍
:石油工业中,常有物料需要以脱氢塔处理后冷凝收集以供出货或下一步加工处理,因此脱氢塔顶冷凝器的工作效率在相当程度上关系该工序实际生产效率。现有的脱氢塔顶冷凝器通常采用常规壳程冷凝方案,其气态进料由顶部管口实现而液态卸料有底部管口实现,该结构虽然可以有效防止液态物料回流,但需要在壳程处另设管阀引出不凝气,且未冷凝的物料亦可能从底部管口溢出,冷凝效果不佳。
技术实现思路
:鉴于此,有必要设计一种脱氢塔顶冷凝器,解决未冷凝物料溢出和不凝气排出不利的问题。脱氢塔顶冷凝器,包括:外壳体、U型管程、壳程进料管、壳程出料管和不凝气排气管;其中,外壳体由两端膨大的圆柱主壳体和通过法兰盘安装在主壳体两端的封头组成;U型管程包括T型挡板、管束和折回腔,T型挡板安装在一侧封头法兰处,其T头伸入封头并与封头内表面连接密封,其T尾为与管束连接的孔板,管束穿过主壳体并与设置在另一封头内的折回腔连接密封;壳程进料管设置在主壳体一侧膨大区,由主壳体顶部进入,环绕主壳体内壁沿至壳体底部;壳程出料管由主壳体另一侧膨大区 ...
