盐泥用于湿法脱硫的研究与应用

Study and application of wet FGD plant using salt mud

本文通过对盐泥的理化性质进行分析,探讨了盐泥作为湿法脱硫原料的可行性,并通过小试和工业化应用,验证了盐泥可以替代石灰石粉作为湿法脱硫原料。该方案不仅可以节省电厂购买脱硫原料的费用,而且为盐泥的安全处置找到了出路,解决盐泥综合利用问题,实现了以废制废、节能减排的目标。

Based on the physical and chemical properties of the salt mud, the feasibility of salt mud used as raw material of the wet desulfurization was discussed in this paper. Through the test and industrial application, it was verified that the salt mud could replace lime stone powder as raw material of the wet desulfurization. It could save the purchase of raw material cost of desulfurization and it found a way to dispose salt mud safely. The problem of comprehensive utilization of salt mud was dissolved. This method could achieve the targets of processing waste by waste, energy saving and emission reduction.
