AI Technical Summary
In the traditional triethylamine cold box core-making process, triethylamine utilization is low, raw material consumption is high, VOCs pollution is serious, conventional exhaust gas treatment has secondary pollution and high operating costs, and existing recycling equipment has poor adaptability and is difficult to modify.
Design a triethylamine circulation system, including a triethylamine supply system, a tail gas recovery system, a gas storage tank and a valve system, to construct a closed-loop circulation gas path. Through bottom amine delivery and top recovery, triethylamine can be efficiently recovered and reused. Reverse airflow and multi-stage filtration are used to ensure gas purity and pressure stability.
It significantly improves the reusability of triethylamine, reduces raw material consumption and VOC emissions, reduces hazardous waste generation, lowers enterprise costs, adapts to existing equipment upgrades, and ensures the quality and efficiency of sand core forming.
