石灰—烟道气法在卤水净化中的应用

Application of Lime Flue Gas Method in the Brine Purification

为了降低生产成本,充分利用现有的烟道气(经过除尘、水洗处理过的锅炉燃烧产生的烟气)资源,并结合我司芒硝型卤水特点的实际情况,利用廉价的石灰和烟道气将卤水中的钙、镁离子除去,为盐硝联产提供合格的精卤,硫酸钠在其中起了特殊作用,为卤水净化生产提供了可靠的参考依据。

To reduce production cost and fully use the current flue gas resource （ the flue gas is from boiler bombustion which is after dust removing and washing）. Removal the calcium ions and magnesium ions by combining with the status quo of the sodium sulfate type brine and the cheap lime and flue gas to provide qualified brine to the co-production of salt and glaubers salt. The sodicum salt palys a special role in it and which provides reference to the brine purification.
