AI Technical Summary
Existing hollow fiber membrane air separation inerting devices have low space utilization and poor connection reliability. Furthermore, when operating at high temperatures, the membrane core is prone to cracking due to thermal strain, which affects nitrogen production performance and service life.
The design employs composite materials, including end caps made of high-strength carbon fiber/epoxy material and a cylinder made of high-modulus carbon fiber/epoxy material. These are integrated into a single structure through a layup process, eliminating flanges and clamps, increasing the amount of membrane filament filling, and designing a reasonable conductive path to ensure connection reliability and matching of thermal expansion coefficients.
It improves space utilization, enhances connection reliability and load-bearing capacity, enables stable operation at temperatures above 150℃, extends device lifespan, and improves nitrogen production performance.
