赤天化纸业公司碱回收炉自2008年投入运行以来,碱回收炉燃烧后的熔融物在熔解槽中经常发生剧烈的爆炸,导致熔解槽的不锈钢内衬发生破裂,4台熔解槽搅拌器振动比较大,运行不稳定,容易损坏;另一方面,溜槽的冷却水夹套经常出现不同程度的开裂,导致溜槽的使用寿命比较短,严重影响了碱回收炉的正常运行。本文结合熔融物溜槽的结构特点,分析了产生问题的原因,并提出了改进方案。
Chitianhua Paper Company alkali recovery furnace put into operation since 2008, the alkali recovery furnace combustion melt often violent explosion in the melting tank, resulting in melting tank stainless steel lining rupture, 4 melting tank mixer Vibration is relatively large, unstable operation, easy to damage; the other hand, chute cooling jacket often have different degrees of cracking, resulting in a shorter life of the chute, seriously affecting the normal operation of the alkali recovery furnace. Based on the structural characteristics of the melt chute, this paper analyzes the causes of the problems and puts forward the improvement plan.
