摘要
甘油甜水蒸发中可能会遇到硫酸钙结垢,垢层增长很快,造成蒸发效率下降,严重影响生产。硫酸钙垢是一种较难清除的结垢,采用盐酸、EDTA都不能很好清除。纯碱-盐酸两步法可以有效去除硫酸钙垢,对设备没有损害。如果在甜水预处理时采取一定的措施,就可以有效预防硫酸钙结垢。
Glycerol sweet water evaporation may encounter calcium sulfate scaling, fouling layer increased rapidly, resulting in evaporation efficiency drops, seriously affecting production. Calcium sulfate scale is a scale difficult to clear, using hydrochloric acid, EDTA can not very well cleaned, soda ash - hydrochloric acid two - step method can effectively remove calcium sulfate scale, on the device is not damaged. If the sweet water pretreatment to take certain measures that can be effective in preventing calcium sulfate scaling.
