Combined desulfurization and denitration method for novel dry-process cement production line
A combined desulfurization and denitration method for a novel dry-process cement production line is disclosed. The method includes adding a raw material modifier and a liquid desulfurization and denitration agent which are two parts into the cement production line. The raw material modifier is added at a raw material elevator, and the liquid desulfurization and denitration agent is added at a windpipe among cyclone preheaters C1-C3. The raw material modifier includes 10-98% of a SO2 absorbent, 0.01-30% of an active component promoting SO2 absorption, 0.01-30% of an active component promotinglimestone decomposition, and 0.01-30% of a denitration catalyst adopting clay as a carrier. The liquid desulfurization and denitration agent includes 0.1-25% of ammonia water, 0.1-40% of a urea solution, or a solution mixture of both. The method has technical advantages of good desulfurization and denitration effects, low cost and no secondary pollution.
本发明公开了一种针对新型干法水泥生产线的联合脱硫脱硝方法。包括向水泥生产线中添加生料改性剂及液体脱硫脱硝剂两部分，所述的生料改性剂在生料提升机处加入，所述的液体脱硫脱硝剂在旋风预热器C1～C3间的上风管处加入；所述的生料改性剂包括10～98％SO吸收剂、0.01～30％促进SO吸收的活性组分、0.01～30％促进石灰石分解的活性组分、0.01～30％以粘土为载体的脱硝催化剂；所述的液体脱硫脱硝剂包括0.1～25％氨水、0.1～40％尿素溶液，或两者的混合溶液。本发明具有脱硫脱硝效果良好、成本低廉、无二次污染的技术优势。
