AI Technical Summary

Technical Problem

Existing CO removal furnaces in argon recovery systems in the monocrystalline silicon photovoltaic industry suffer from uneven gas distribution, resulting in incomplete removal of CO impurities, uneven wear of the packing layer, short service life, and safety risks.

Method used

Design a CO removal gas furnace with a flow equalizer, including an inlet section, a CO removal section and an outlet section. The flow equalizer is set at the bottom of the inlet pipe, and its frustum-shaped structure is aligned with the packing layer. A straight pipe at the bottom connects to the packing layer. Circular holes are arranged in a crisscross pattern to ensure uniform airflow. The packing layer consists of a water absorption layer and a CO removal layer. The flow equalizer is welded and fixed to the inlet pipe.

Benefits of technology

It achieves uniform airflow distribution, improves the utilization rate of the packing layer, extends service life, reduces impact risk, and enhances argon purity and equipment safety.
