氨洗涤法烟气脱硫氨洗涤法烟气脱硫ammonia scrubbing flue gas desulfurizationor、x一d一fo yonqz tuol一u氮洗涤法烟气脱硫(ammonia serubbing fluegas desulfurization)用氨作为吸收剂对烟气进行洗涤吸收的脱硫工艺。脱硫效率可达93%以上;消耗It氨，约可生成3.gt硫酸钱。工艺流程脱硫系统主要由一级洗涤塔、二级洗涤塔、氧化器、原料氨供给系统和副产品加工系统组成。简化工艺流程如图所示.由锅炉来的烟气通过气/气换热器使烟温降低到110C左右，在进人一级洗涤塔之前，采用二级洗涤塔抽出的洗涤液喷淋激冷使烟气温度降低到饱和温度。之后进人一级洗涤塔.由碱性氨水洗涤液脱除80%左右的50:。烟气经过雾沫分离器后，再进人二级洗涤塔.进一步脱除10%左右的Sq。在两级洗涤塔中按照式(l)、(2)进行化学反应生成亚硫酸钱和亚硫酸氢按溶液。┌────┐ │日 │ ├────┼──┐│介‘’‘│‘肋│└────┴──┘氨洗涤法烟气脱硫工艺流程图l一氧化器;2一气/气换热器;3一一级洗涤塔;4一雾沫分离器;5一二级洗涤塔;6一高效雾沫分离器502十ZNH3+HZO一(NH。):S()3 502+NH3+HZ()一NH。HS()3(l)(2)脱硫后的烟气经过二级洗涤塔中的高效雾沫分离器，使烟气中呈气溶胶状态的氨逸出量降低到lomg/m3以下。之后经过气/气换热器使烟温由50C左右提高到排烟所要求的温度，然后引人烟囱。从第一级吸收塔抽出部分亚硫酸按和亚硫酸氢馁组成的混合液引人氧化器，同时向氧化器内通人适量氨水和空气，按式(3)和式(4)进行化学反应生成硫酸按.按照氧化器中反应产物密度调整抽出量，送人副产品制备系统，使其生成固态颗粒状硫酸按。把副产品制备系统中产生的废气冷凝液送回二级洗涤塔，使其中的碱性物继续参与脱硫。 (NH‘)2503+1/202~(NH。):50;(3)NHoHSO3+NH3+1/202~(NH‘)25()。(4)技术特点氨洗涤法是一种既不产生废水，也不产生任何工业垃圾的脱硫工艺。副产品是可以达到等级标准的硫酸按化肥，也可以作为氮碑钾复合肥的配料。但是，硫酸铁吸水性较强，如果不能及时销售就必须特殊处理，以免造成二次污染。氨洗涤法还可以使烟气中其他微量酸性组分如HCI和HF等转化为按化合物，其在副产品中的含量是商业标准可接受的。如在烟气上游采用氨基选择性催化或非催化还原(scR或SNCR)脱NO二工艺，则上游逃逸的氨反应剂自然会在下游脱硫系统内耗尽。见烟气S()2/N仪联合脱除技术。发展历史该工艺由德国的瓦尔特公司(Walthe依Cie AG)首先研究开发。
