AI Technical Summary

Technical Problem

Existing activated carbon adsorption towers are prone to aging and cracking of the sealing surface and micro-leakage at the flange connection, making it impossible to monitor the leakage status in real time, which poses a safety hazard.

Method used

The system employs a dual-seal protection assembly, including a fluororubber sealing ring and an expansion sealing ring, combined with a miniature air pump and a sensor to achieve double sealing. The fluororubber is corrosion-resistant, and the expansion sealing ring adaptively compensates for the flange face gap through inflation. The sensor monitors and compensates for leakage in real time.

Benefits of technology

It improves sealing performance, avoids static seal failure and instantaneous micro-leakage, enhances the safety and durability of the equipment, and enables real-time monitoring and compensation for leaks.
