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.
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.
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.
