Description
技术领域
本发明涉及燃煤添加剂，特别是用于工业锅炉、电站炉、蒸汽炉和生活燃煤的以油页岩为载体的环保节能的燃炭节能洁净增值剂。
背景技术
工业锅炉和电站炉是燃煤炉，也是造成大气污染(包括SO2，CO2及烟尘等)的主要污染源之一。市场上现有的燃煤添加剂种类较多，单一作用较好，综合效果差。
中国专利95115467.2公开的一种“煤炭添加剂”由高锰酸钾、硝酸纳(或硝酸钾)、氯化钾按适当比例简单混合而成，其添加剂氯化钾占80％以上，由于氯成份过高，对金属物有较强的腐蚀性，不便仓储，同时脱硫效果也不理想。
中国专利200610032354.X公开了“一种煤炭添加剂”它以有机物腐植酸为载体，腐植酸含固定炭量为5％，不能起到助燃的作用，其产品锅炉热效率提高9.19％，炉渣含炭量降低14.86％。
发明内容
本发明的目的是提供一种以油页岩为载体的煤炭节能洁净增值剂，它能真正助燃，促使燃烧充分、提高热效率，又可消焦，消烟，固硫、缓蚀延长锅炉使用寿命，环保节能。
本发明煤炭节能洁净增值剂技术方案的组分配比是：油页岩40-81％、腐植酸10-15％、酸化煤矸石2-6％、硝酸钠3-10％、高锰酸钾1-5％、硫酸铝3-6％、氯化钠1-10％、碳酸钙5-10％、碳酸钠2-8％、二氧化锰3-7％、磷酸钠3-5％、轻质氧化镁5-10％。上述组分原料按百分比重量，混合粉碎，粉末细度20-40目，再放入搅拌机内搅拌5-10分钟，检验包装即为成品。
上述煤炭节能洁净增值剂油页岩的组分配比最好为68-81％。
本发明的煤炭节能洁净增值剂以油页岩为载体，油页岩的储量要比煤、石油或天燃气多得多，我国是世界上油页岩储量最丰富的国家之一，已探明的油页岩诸量达70多亿吨，因此原料丰富。油页岩的组成主要为油母、水分和矿物质，其中油母是一种复杂的高分子有机化合物。油母的组成元素主要为碳、氢，以及少量的氧、氮、硫，水份为4-25％，矿物质主要有石英、高岭土、云母、碳酸盐岩及硫铁矿，油母的含量约10-15％，为低热值固态化燃料，具有与石油相同的作用。因此可直接用于电站炉、锅炉燃料，同时具有助燃，提高热效率的作用。
清焦成份中除常用的碳酸钙外还增加酸化煤矸石，酸化煤矸石为天燃的膨值剂，它可使炉壁结焦共熔物分解温度降低，分解速度加快，在腐植酸[R-(COOH)N]活性基团所特有的离子交换性，综合性大表面性的作用下，改变共熔物的物理状态和化学成份，使其多孔、酥松、翘起，随炉内强热流翻动脱落，清焦效果明显，从而改善了锅炉热传导，提高了氧化剂的助燃、消烟效果。
缓蚀剂中，腐植酸[R-(COOHn)]的羰基、酚基等活性基团的离子交换性，氧化还原性等特殊作用，促进炉膛内金属表面Fe3.O4保护膜的形成，起到防腐、缓蚀作用。
消烟剂：高锰酸钾既为消烟剂也可为助燃剂。
固硫剂成份中，除了常用碳酸钙外，还增加了二氧化锰、轻质氧化镁，缩短了在炉内高温条件下生成硫酸盐的时间，提高了固硫脱硫效果。
采用本发明的煤炭节能洁净增值剂，具原料丰富，生产工艺简单、投资少、见效快，使用方便，经有关环保、节能部门检测其固硫脱硫率达80％以上，锅炉热效率提高16.8％，炉渣含碳量降低56.7％，清焦、消烟、缓蚀经使用单位实践证明均在95％以上等优点和效果。
