碳酸钾是酿造、肥料、鞣革、医药、漂白等行业的重要化工原料,目前较为紧缺。很多植物秆壳含有丰富的钾盐,如棉籽壳、桐籽壳、菜籽壳、棉秆、豆秸秆等都是制取碳酸钾的原料。一、主要设备浸出液池、蒸发缸、结晶池、离心机、反射炉、粉碎机和计量器。二、工艺流程秆壳灰用水浸提→蒸发结晶→ Potassium carbonate is brewing, fertilizer, tannage, medicine, bleaching and other industries important chemical raw materials, the current shortage. Many plant stalks are rich in potash, such as cottonseed hulls, Tong hulls, rapeseed hulls, cotton stalks, bean stalks and other raw materials are made of potassium carbonate. First, the main equipment leaching liquid pool, evaporation cylinder, crystal pool, centrifuge, reflex furnace, grinder and meter. Second, the process of stalk shell ash leaching → evaporation crystallization →
