煤气化锁斗高压过滤器滤芯断裂原因及改进措施

Fracture causes analysis and prevention for filter element of lock hopper high pressure filter

为了减少和避免煤气化锁斗高压过滤器滤芯的断裂,降低设备故障率,提高煤气化装置的开车率和保证其长周期稳定运行,研究了多个项目现场中的滤芯断裂状况。结果表明:滤芯的断裂状况大都相似,断裂部位大都在滤芯根部且往往伴随有滤芯管体的弯曲。综合分析了滤芯断裂的原因,提出了相应的改进措施和注意事项。

To avoid the fracture of filter element of lock hopper high pressure filter and lower failure rate, improve the using efficiency of coal gasification equipments and stabilize operation, investigate filter element fracture situations in many projects. Find that the fracture situations are mostly similar, most fractures occur in the root of filter element and sometimes associate with filter element body bending. Analyse the fracture reasons, and provide corresponding improvement.
