反应釜操作人员思想放松安全隐患大
发布者:admin  日期:2016-05-26  点击:2048

  反应釜一般在常压或敞口下进行反应,蒸馏釜一般在常压或负压下进行操作。有人认为,在常压、敞口或负压下操作危险性不大,往往在思想上麻痹松懈,不能及时发现和处置突发性事故的苗头,最终酿成事故。实际上常压或敞口的反应釜,其釜壁承受的压力要大于釜内承压的反应釜,危险性也更大一些。

Reactor is generally undernormal pressure or exposure to the reaction, distillation is generally undernormal pressure or negative pressure operation. It is argued that underatmospheric pressure, exposure, or negative pressure operation risk is not big,often in thought lax, could not be found in time and signs of sudden accidentdisposal, ultimately lead to accidents. In fact, atmospheric pressure orexposure of the reactor, the pressure of the tank wall pressure is greater thanthe pressure of the reactor, the risk is greater.

 

    对于蒸馏釜,如果作业人员操作失误,反应失控造成管道阀门系统堵塞,正常情况下的常压、真空状态变成正压,若不能及时发现处置,本身又无紧急泄压装置,很容易发生火灾爆炸事故。

For distillation kettle ifoperator error, as runaway reactions resulting in clogging of piping and valvesystem, under normal atmospheric pressure and vacuum state into a positivepressure, if not timely discovery disposal, itself and no emergency pressurerelief device, it is prone to fire and explosion accidents.

 

20071127日江苏盐城市联化科技有限公司重氮化反应釜爆炸事故,就是因为重氮化反应釜蒸汽阀门未关死,在保温阶段仍有大量蒸汽进入反应釜夹套,导致反应釜内温度快速上升,重氮化盐剧烈分解,继而爆炸。当班操作工人对釜温的监控不到位,未能及时发现釜内温度异常,延误了处置异常情况的最佳时机。

2007 November 27, Yancheng,Jiangsu, alliance of science and Technology Co., Ltd. diazotization reactionkettle(www.gfanyingfu.com) explosion, is because the diazotization reaction kettle steam valve doesnot shut, during the holding period still have large quantities of steam intothe reaction kettle jacket, resulting in a rapid increase in reactortemperature, salt nitride play strong decomposition, and then exploded. Shiftworkers to operate on the reactor temperature monitoring is not in place,failed to find abnormal temperature in the reactor, delayed the best time fordisposal of abnormal.
