Abstract
本专利公开了一种建材工业燃料替代碳中和的方法，在燃烧器中通入氢气、原子吸收剂、惰性气体、氧调节剂、改性缓燃剂，分别从燃烧器不同通道喷出，并在燃烧器喷口外混合、燃烧，得到稳定、长度可调的火焰。同已有技术方案相比，本方法操作简单，成本低，燃烧温度范围宽。
Description
技术领域
本发明涉及建材工业碳中和领域，具体涉及水泥或石膏工业用燃料替代，即用氢替代煤或天然气的方法。
背景技术
建材工业中二氧化碳排放量最大的是水泥工业，水泥工业是世界第三大能源消耗行业，占据工业能源消耗的7％，也是世界第二大二氧化碳排放行业，占全球二氧化碳排放的7％。我国水泥工业2020年碳排放约13.2亿吨(含电力消耗)，约占建材工业的80％，约占全国的13.5％。水泥工业对我国建材工业实现“双碳”目标影响重大。水泥工业的碳排放主要来源是生产电耗、燃料燃烧和原材料碳酸盐分解。按照相关现行国家标准取值计算，每吨水泥的二氧化碳排放约为675千克；其中，生产电耗间接排放约占11％，燃料燃烧直接排放约占31％，原材料碳酸盐分解直接排放约占58％[齐冬有，张标，罗宁.建材工业碳中和[J].中国建材，2021，(7)：92-97]。
氢气作为一种价值丰富的商品气体和化学原料，可以成为可再生能源转换的能量储存载体。将电解水技术与可再生能源发电相结合，可将多余的电能以化学能的方式储存在氢气中，平抑可再生能源波动，提高消纳水平，推进能源清洁化替代[赵雪莹，李根蒂，孙晓彤，等.“双碳”目标下电解制氢关键技术及其应用进展[J].全球能源互联网，2021，4(5)：436-446]。利用可再生能源制取的“绿氢”还可直接应用于建材工业替代碳质燃料，为实现深度碳减排提供有效途径。
氢气易燃易爆、燃烧范围宽(4％-75％)、点火能量低、扩散系数大，氢气火焰的稳定性差。本发明通过添加外加剂改变燃料气体组成，并通过合理设计燃烧喷嘴，改变氢气的燃烧速度，实现氢气在现有水泥窑炉或石膏生产炉中的应用。
发明内容
为解决现有技术存在的问题，本发明提供了一种建材工业燃料替代碳中和的方法，同已有技术方案相比，本方法操作简单，成本低，燃烧温度范围宽，具有容易在现有窑炉中应用的特点，具有显著的经济效益和社会效益。
一种建材工业燃料替代碳中和的方法，包括以下步骤：
在燃烧器中通入氢气、原子吸收剂、惰性气体、氧调节剂、改性缓燃剂从燃烧器不同通道喷出，并在燃烧器喷口外混合、燃烧，得到稳定、长度可调的火焰；其中，改性缓燃剂为缓燃剂与表面活性剂混合均匀得到。
所述原子吸收剂为重油、煤焦油、裂解残渣中的一种，加入量为氢气质量10-50％。
所述惰性气体为氮气、二氧化碳、水蒸气中的一种，加入量为氢气质量10-50％。
所述氧调节剂为铁渣粉、锡渣粉、铜渣粉中的一种，加入量为氢气质量0.1-2.0％。
所述缓燃剂为废塑料粉、淤泥粉、养殖场废物中的一种，加入量为氢气质量100-500％。
所述表面活性剂为三乙醇胺、丙三醇、甲酸钙中的一种，加入量为氢气质量0.1-2.0％。
所述燃烧器为多通道喷燃料管，喷口设有钝体和导流叶片。
相对于现有技术，本发明具有以下优点：
氢气为绿电电解水产氢、光解水产氢、微生物产氢中的一种，这些氢均能在本发明中得到同样的效果。绿电为太阳能、风能、水能、潮汐能、核能、地热能产生电的一种，这些电具有不排二氧化碳的特点；电解水的方法为碱性溶液电解水、固体高分子膜电解水、高温水蒸气固体电解质电解水中的一种。光解水产氢，光解水制氢是指利用光催化技术催化分解水制氢，水是一种非常稳定的化合物，通过光和半导体光催化剂共同作用实现此反应过程。产氢微生物为常见微生物，即光合微生物，主要包含了绿藻、蓝细菌和厌氧光合细菌。可见，氢气为绿氢，可再生。
氢气燃烧时产生活性原子，燃烧为链式反应，燃烧速度快。原子吸收剂对原子进行吸收，减少活化中心，减缓氢气的燃烧速度，有利于火焰的调控。原子吸收剂为重油、煤焦油、裂解残渣中的一种。重油是原油提取汽油、柴油后的剩余重质油，其特点是分子量大、黏度高。煤焦油为煤炭干馏时生成的具有刺激性臭味的黑色或黑褐色粘稠状液体。裂解残渣为废矿物油裂解再生过程中产生的裂解残渣。原子吸收剂可与氢原子反应实现加氢，原子吸收剂加氢反应后，粘度下降，流动性增加，有利于在燃烧区分散，有利于与其它燃料混合，有利于火焰稳定。在燃烧器中，氢气为原子吸收剂的载气体。
惰性气体为氮气、二氧化碳、水蒸气中的一种，可稀释氢气的浓度，减缓氢气的燃烧速度。惰性气体还作为改性缓燃剂的载送气体，携带改性缓燃剂从燃烧器喷口喷出。
氧调节剂为铁渣粉、锡渣粉、铜渣粉中的一种。铁渣粉为含铁渣粉，为锌冶炼厂产生的铁矾渣脱硫后所得渣、硫铁矿制酸后所得渣、或铁尾矿渣中的一种。锡渣粉为含锡渣粉，为锡冶炼过程中产生的渣、或电子废弃物中含锡的渣中的一种。铜渣粉为含铜渣粉，为冶炼铜过程中产生的渣或电子废弃物中含铜渣中的一种。氧调节剂可以根据火焰燃烧的气氛吸收或放出氧，确保氢气的稳定燃烧。氢气为氧调节剂的载气体。氧调节剂燃烧后，进入水泥矿物中，可将水泥矿物中的六价铬还原成三价铬，具有降铬剂的功效，铬的还原率达100％。
缓燃剂为废塑料粉、淤泥粉、养殖场废物中的一种，废塑料粉为塑料垃圾粉碎后得到的粉体，淤泥粉为城市生活污水处理过程中产生的淤泥烘干、粉磨得到的粉体，养殖场废物为动物的粪便烘干、粉磨得到的粉体。缓燃剂燃烧速度慢，在其燃烧前吸收氢气燃烧产生的热量，减缓氢气燃烧速度。缓燃剂为废弃物，对其进行利用，避免污染环境。
表面活性剂为三乙醇胺、丙三醇、甲酸钙中的一种，表面活性剂吸附在缓燃剂表面，避免缓燃剂团聚，有利于缓燃剂分散，提高缓燃剂的燃烧效率。
燃烧器根据目前水泥厂常用的喷煤管结构设计，为2-4通道。喷氢通道设有钝体和喉口，喉口减小通道面积，增加氢气流速，避免氢气燃烧回火；钝体避免氢气燃烧脱火，保持氢气燃烧稳定。在缓燃剂喷口，设有导流叶片，使缓燃剂按旋转向前的螺旋轨迹运动，有利于缓燃剂与氢气的混合。4通道喷口的燃料从外到内为：(改性缓燃剂+惰性气体)/(氢气+原子吸收剂+氧调节剂)/(改性缓燃剂+惰性气体)/(氢气+原子吸收剂+氧调节剂)，3通道喷口的燃料从外到内为：(改性缓燃剂+惰性气体)/(氢气+原子吸收剂+氧调节剂)/(改性缓燃剂+惰性气体)，2通道喷口的燃料从外到内为：(改性缓燃剂+惰性气体)/(氢气+原子吸收剂+氧调节剂)。
燃料燃烧所用氧气来源于冷却设备的二次风或水电解产生的氧气。
