本工艺流程是回收气体中的氟,生产低分子比的冰晶石,具体作法是: 1.把含氟气体送入吸收塔,与含铝酸钠的吸收液接触发生反应,并在吸收液中生成以碱性氟化铝和冰晶石为主的固相; The process is to recover fluorine gas, the production of cryolite cryogenic ratio, the specific approach is: 1. Fluorine gas into the absorption tower, and sodium aluminate absorption solution in contact with the reaction, and in the absorption solution Generate basic aluminum fluoride and cryolite-based solid phase;
