合成氨厂用的高压容器,是氮肥制造设备中最主要的装备之一。一套年产25000吨合成氨的高压容器,由水洗塔、锏液塔、碱液塔、滤油器、合成塔、氨分离器、氨蒸发器、冶凝塔及水冶凝器等九种容器粗成,其工作压力大多为130～320公斤/厘米~2,工作介质主要为 H_2、N_2、NH_3等。本文就当前年产25000吨合成氨高压容器焊接生产中的一些问题,主要是层板包扎式的容器筒壳、高压管及某些内件的焊接工艺(本文—至五节)与材料(本文第六节),提出几点个人的看法,谬误之处,希望大家指正。
Ammonia plant with high pressure vessels, nitrogen fertilizer manufacturing equipment is one of the most important equipment. An annual output of 25,000 tons of ammonia high-pressure containers, from the washing tower, liquid tower, lye tower, oil filter, synthesis tower, ammonia separator, ammonia evaporator, Crude, the working pressure is mostly 130 ~ 320 kg / cm ~ 2, the working medium is mainly H_2, N_2, NH_3 and so on. In this paper, the current production of 25000 tons of synthetic ammonia pressure vessel welding some of the problems, mainly laminated layering container shell, high pressure pipe and some of the internal welding process (this - to five) and materials (article Six), put forward a few personal views, fallacies, I hope you correct me.
