AI Technical Summary

Technical Problem

Existing modular activated carbon adsorption boxes suffer from insufficient sealing between modules, allowing gas to flow across modules. This results in localized underutilization of activated carbon, low adsorption efficiency, and uneven gas distribution, which can easily lead to channeling or short-circuiting. Consequently, the adsorption capacity is only 60% to 70% of the theoretical value.

Method used

The honeycomb-patterned docking block and guide plate structure, combined with sealing components, ensure uniform airflow distribution, extend the contact time between gas and activated carbon, and guide the airflow in a 'wave-shaped' path through the inclined guide holes of the guide plate to enhance the contact effect between gas and activated carbon.

Benefits of technology

It improves gas adsorption efficiency, avoids local high-speed impact, prolongs the contact time between gas and activated carbon, enhances adsorption capacity and efficiency, and ensures uniform utilization of activated carbon.
