如果气化炉炉体出现了泄漏现象,应该怎样补救? 对于德士古炉子,壳体出现泄露,建议马上倒炉,问题炉子停车处理。为什么要马上停车呢?因为德士古炉子壳体内衬有耐火砖,虽然燃烧室温度高达1300度,但是壳体的温度一般只是在250左右。也就是说,通过耐火砖的隔热和隔气,壳体处在一个相对安全的运行环境。壳体泄露(正常应该先在焊缝处出现),说明工艺气已经可以穿透耐火砖,也就是说,热源也可以直接到达壳体,这样,继续泄露的话,泄露部位的温度就会继续升高。过高的温度将导致壳体强度减弱,在工艺气的压力作用下,泄漏口将继续扩大或者导致泄漏处壳体膨胀鼓出,危险性加剧。再说,高温工艺气喷出,也极易燃烧起来,威胁周围环境的安全,特别是作业人员的安全。所以,发现泄露随即安排停车很关键。 如果不是气化炉这种特别地方,如果只是泄露,而且量小,泄露部位也很稳定,倒是可以采用外部加氮气稀释等方式延长使用,择机处理,或者等待准备工作做好后马上停车处理。 气化炉停车并处理后,确认泄露部位,拆除该处区域的耐火砖,联合检测部门确定处理范围,联系维修单位确定处理方案准备工器具和材料(sa387不好找,应该寻求气化炉制造厂提供材料。如果只是焊缝问题,就相对简单一些),现场修复(焊缝打磨后重新焊接或者需要局部更换壳体材料),完后再次监测确认质量,耐火砖重砌,烘炉。然后转入后续工作。 需要说明的是,处理时要注意热处理工序的正确性。 且不要随便堵漏,热工艺气会损坏卡具;而且,也不便于观察泄露部位的扩张;再说,大直径的高压壳体做卡具并固定也是困难的问题。查看更多

各位亲身经历的生产事故,都说出来吧.? 我也说一下: 04年12月23日凌晨,车间操作工开始离心甲苯液,由于冬天空气特别干燥,是静电容易产生的季节,离心机工作时产生了静电,甲苯液着火,烧掉了半个车间,一名操作工被烧成轻伤,幸好没有大的人员伤亡。 我公司平时安全部门经常强调静电问题,但因没亲身经历就没太在意当时离心机的静电接地情况,从而导致事故的发生。 因此我建议化工同行们,易燃溶剂存在的产品过滤时,尽量不要用离心机,我们现在都改成了板框压滤机,效果还不错。 还有一次由于产生静电发生的小事故说给大家,望引起重视: 一次操作工在向盛有溶剂的釜内加固体料时,由于物料与编织袋摩擦产生静电,引燃溶剂,虽未发生爆炸,但也烧伤工人的面部。 查看更多

拱顶罐可不可以改成内浮顶? 设计不同,如果改成浮顶罐,那么必然要增加排水管线,那么罐底就必需重新安装排水管线的轨道,就算是用金属软管的排水管,也要固定架,那么浮盘下面也要安装固定架。必然引起焊接变形和应力增大,所有说能更改的前提是不要怕灌报废查看更多

低压瓦斯的利用? 我想提醒下楼主。 我们装置曾用过低压瓦斯进加热炉焚烧。由于我们装置原油硫含量高(1.69),结果下来空气 ... 嗯,我们加工的油比较杂,以渤海产的原油为主25-2 28-1 9-3 之类的都是经常加工的油。 不过干气是经过脱硫的,低压瓦斯只有两个火嘴,应该不会有很大的问题吧。不过现在排烟压的比较低。 查看更多
