不久前,某造纸厂化工车间发生了一起凝结水回收槽爆炸的事故.强大的爆破力撕裂了槽顶和槽身连接处80%的焊缝,并将人字形顶呈60°上掀,裂口成荷叶状变形.幸亏事发时无人在场而未酿成惨祸,但这一事故的起因却值得我们思索.该凝结回收槽容积约1.7m~3,立式平底人字形顶,桶体壁厚6mm,材质A3.顶上接有Dg60凝结水进水管三根和Dg125对空排放管一根,下距底100mm处接有Dg80出水管一根,用法兰直接于2.5N3×2凝结水泵,并配装玻璃管水位计和压力表式温度计各一只.整个槽体用石棉保温.
Not long ago, an accident occurred in a chemical plant in a paper mill where a condensate recovery tank exploded.A powerful blast force ruptured 80% of the weld between the top of the tank and the tank body and raised the crest 60 ° upward, Split into a lotus leaf deformation fortunately no one was present at the time of the incident without causing tragedies, but the cause of the accident is worth our pondering the condensate recovery tank volume of about 1.7m ~ 3, vertical flat herringbone top, barrel Body wall thickness 6mm, material A3. Dg60 condensate inlet pipe connected to the top of three and Dg125 empty discharge pipe, the next from the bottom of 100mm Dg80 outlet pipe connected with a flange directly in the 2.5N3 × 2 condensate pump , And equipped with a glass tube water gauge and pressure gauge thermometer each one of the entire tank insulation with asbestos.
