摘　　要：随着环保要求的提高以及芳烃工业的发展,大量的连续重整装置建成投产。反应器和再生器是连续重整装置中的核心设备之一,轴向条形筛网是制造其内部构件中心管和内外网的主要元件。在实际运行中,由常规轴向条形筛网制造的反应器和再生器的内件发生了较多的失效破坏,直接影响到了装置的正常连续生产。新型轴向条形筛网克服了传统轴向条形筛网的缺点,能够满足连续重整装置苛刻的工艺环境。A lot of continuous catalytic reforming （CCR） units have been established and com- missioned along with the more high requirements of environmental protection and the develop- ment of aromatics industry. The internals applied in the reactor and regenerator which is one of the core equipments of CCR unit, such as center-pipes, inner and outer screens were mainly made up of axial screens, which is very important to keep the reaction and regenerating process. How- ever many center-pipes failures of reactor and inner and outer screens for regenerator have been happened in the running unit, which was made of traditional axial screens, the normal continuous production cannot be processed. The optimized axial screens which could overcome defects of tra- ditional axial screens were described, and it could be subjected to the conditions of CCR unit.
