容器受热引起爆炸事故原因分析
发布者:admin  日期:2016-06-02  点击:1943

  反应釜由于外部可燃物起火,或受到高温热源热辐射,引起容器内温度急剧上升,压力增大发生冲料或爆炸事故。

Because of the fire of theexternal fuel, or the heat radiation from the high temperature heat source, thetemperature of the container is increased rapidly, and the pressure of thereactor is increased.

 

1991108650分,江苏淮阴有机化工厂中试室,1台生产高分子聚醚的100L高压反应釜突然发生爆炸,连接釜盖和釜体的紧固螺栓被拉断,重量约为80kg的釜盖飞落到离原地80多米的地方,高压反应釜上安装的安全阀、压力表等也被炸毁。爆炸产生的气浪将房顶掀掉,约20m3的中试室完全倒塌,3名操作人员当场被炸死。

1991 October 6 days 8 when50 minutes, organic chemical factory in Jiangsu Huaiyin test room, a productionof high molecular polyether 100L autoclave suddenly exploded, fastening boltsconnecting the kettle cover and the kettle body is pulled off, weight about80kg kettle cover alight on 80 meters from the in situ and high pressure safetyvalve should be installed on the vessel, pressure gauges, etc. were alsodestroyed. The explosion blast ripped off the roof, about 20m in the test roomfand completely collapsed, 3 people were killed on the spot.

 

  该起高压反应釜的爆炸是由于超温超压引起的,以环氧乙烷和环氧丙烷为原料生产高分子聚醚的生产工艺要求操作者严格按规定操作,在加料时应采用“滴”加法,控制加料量,以避免反应剧烈后失控造成危害。但该厂操作人员违反了操作工艺,采用了“批”加法,一次投料过多,反应速度过快。

The high-pressure reactionkettle www.fanyingfuw.com of explosion is due to the over temperature, over pressure caused by,with epoxy ethane and propylene oxide production process as the raw materialsfor the production of high molecular polyether requires the operator tostrictly according to the rules of operation, at the time of charging should beusing "drop" addition, control the feeding amount, in order to avoiddrastic reaction out of control cause harm. But the plant operator in violationof the operation process, using the "batch" addition, a feeding toomuch, the reaction rate is too fast.
