Description

炭黑生产方法及生产系统 技术领域 本发明涉及一种炭黑尾气处理和应用的新工艺，尤其涉及一种以炭黑尾 气#丈炭黑生产燃料循环利用的方法及其系统。 背景技术 目前， 炭黑在工业上是通过使原料油 （例如煤焦油、 乙烯焦油）在反应 炉中进行高温裂解而获得， 过程中需要不断向反应炉通入燃料油以提供用来 维持反应炉高温的热源。 图 1是现有的一种用于生产炭黑生产工艺的流程示 意图。 如图 1所示， 作为燃料的煤焦油和空气在燃烧室 7中燃烧， 产生的高 温高速气流轴向通过燃烧室 7后部的喉管 11 , 在喉管位置径向喷入原料油， 原料油在反应炉 4内高温裂解而生成炭黑。 炭黑通过袋虑器 8分离后， 通过 风机送至造粒机 9造粒， 造粒机 9将粉状炭黑造粒得到直径 0.5 ~ 0.8mm左 右的粒状， 通过千燥机 10 千燥得炭黑成品， 送入产品储罐包装入库。 出自 袋虑器 8的炭黑尾气一部分被送入尾气燃烧炉 31 燃烧， 为炭黑千燥装置提 供热能。 另一部分送尾气锅炉燃烧， 产生的蒸汽用于发电。 传统的燃料油是使用煤焦油、 乙婦焦油、 蒽油等燃料， 其雾化效果影响 因素较多， 导致燃烧不稳定， 温度变化比较大， 从而影响工艺的稳定性和炭 黑的质量。 如前所述，分离出的炭黑尾气一部分送尾气燃烧炉燃烧给炭黑千燥提供 热能， 剩余部分送尾气锅炉燃烧产生蒸汽， 蒸汽带动蒸汽汽轮机工作发电， 产生的电能给炭黑装置供电。 然而通过这种方式其能量的利用率只有 13- 19%。
发明内容 本发明针对上述不足， 提出一种新的生产炭黑的方法和系统， 以降低在 生产过程中的能耗。 本发明的方法包括下述步骤： a、 使分离出炭黑后的炭黑尾气冷却， 以 冷凝其中的水分； b、 分离出该冷凝的水分， 得到千燥的碳黑尾气； c、 预热 上述炭黑尾气， 然后将其送入炭黑燃烧室， 代替燃料油做燃料， 为炭黑反应 供热。 作为优选， 可以在水分分离步骤之后附加一个千燥步骤， 以更充分地吸 收尾气中的气态水， 提高燃烧热值。 作为更进一步的优选， 可以再附加一个 除去炭黑尾气中的氮气的步骤， 此目的也是为了提高尾气燃烧热值。 空气或富氧空气通过主供风机加压后进入高温空气预热器加热，将空气 或富氧空气加热到 600 ~ 900°C后送到炭黑反应炉的燃烧室， 与经过净化、 千 燥、 分离、 预热后的尾气混合燃烧。 本发明还涉及一种通过裂解原料油生产炭黑的生产系统 ,该系统包括袋 虑器、 反应炉、 尾气混合器、 冷却器、 预热器等， 在袋虑器与反应炉之间按 顺序设置冷却器、 汽水分离器、 尾气预热器、 尾气混合器。 优选地， 在汽水 分离器和尾气预热器之间加设千燥器和除氮气装置， 其中千燥器用于除去尾 气中的少量气态水分。 该除氮气装置通常为分子筛系统。 通过本发明的方法或系统，可以用尾气中的可燃气体全部或部分替代燃 料油， 从而提高资源利用率。 通过本发明， 无论是硬质炭黑生产还是软质炭黑生产， 都可以不使用高 热值的燃料油或天然气， 而是使用其炭黑装置本身产生的尾气， 实现资源的 循环利用， 其能量利用效率由传统的 13-19%提高到 65-80%。 通过改进后， 就可以不使用燃料油。 以一条年产 2.5 万屯炭黑生产线为例， 燃料油每小时 需求约 550-650kg, 取 550kg/h, 年按 8000小时计算， 每年可节约燃料油（煤 焦油） 4400 屯；， 煤焦油按 2000元 /屯计算， 可节约 880万元， 仅 jt匕就可以 大大降低成本； 同时还可以改善炭黑质量。 所以， 通过本发明， 使炭黑尾气 变废为宝， 有利于加强环境保护和实现对资源的综合利用。 附图说明 图 1为现有炭黑生产工艺流程结构示意图。 图 2 为本发明以炭黑尾气做炭黑生产燃料循环利用的工艺流程结构示 意图。 具体实施方式 根据本发明的工艺流程通常分两个部分，第一部分是对炭黑尾气的净化 处理， 其工艺步骤为： 经过袋虑器分离后的炭黑尾气通过冷却系统冷却到常 温， 再对冷却后的气体进行汽水分离和千燥， 分离后的气体通过分离氮气后 加热， 送往炭黑反应炉的燃烧室。 第二部分是对处理后的炭黑尾气与预热后 的空气或富氧空气混合燃烧， 其工艺步骤为： 将氧气与空气混合， 通过主供 风机加压后送入空气换热器 A加热到 600 ~ 900 °C送往炭黑反应炉的燃烧室， 燃烧室前段混合器将净化后的尾气和加热后的富氧空气进行充分混合后， 进 入燃烧室燃烧， 为炭黑反应、 裂解提供热量。 图 2是本发明一个优选实施例的炭黑生产流程示意图。 如图 2所示， 经 袋虑器分离出大部分炭黑的尾气通过尾气冷却器 2冷却， 让尾气中的水蒸汽 全部冷凝成液态水， 再通过汽水分离器 3进行汽-水分离， 将所有的冷凝水全 部分离出来， 汽水分离后的尾气还可进一步通过千燥器 13 千燥后， 并进入 分子筛系统 14以分离出氮气， 分离后的可燃气体一部分送往尾气燃烧炉 31 燃烧,为炭黑千燥加热提供热量； 其它通过尾气预热器 6加热， 加热后的尾气 送往燃烧室 7作为燃料。 空气或富氧空气，通过主供风机 1加压，再通过高温空气预热器 5加热， 将富氧空气加热到 600-900 °C送到燃烧室 7与经过净化、 千燥、 分离、 预热 后的尾气通过尾气混合器混合后， 进入燃烧室 7燃烧， 为炭黑反应裂解提供 热能。 由于使用炭黑尾气替代燃料油， 那么在燃烧室内达到相同的燃烧温度， 所产生的热气量会比使用燃料油大得多， 在通过相同横截面积的喉管时， 其 流速会更高， 原料油在喉管处喷入， 给原料油的裂解提供了更大的能量， 使 原料油反应更加剧烈， 强度更高， 从而使炭黑的粒径更加均匀， 提高了炭黑 的结构， 加强了炭黑对橡胶的填充和补强作用。 也就是提高了炭黑的品质。 另外， 由于进入反应炉热气量增大， 带入的热量就越大， 这些增加的热 量就可以供更多的原料油生成炭黑。 因此， 提高了产能。
