Description

一种球形活性炭及其制备方法
技术领域
本发明涉及环保技术领域，尤其是涉及一种球形活性炭及其制备方法。
背景技术
活性炭又称活性炭黑。是黑色粉末状或块状、颗粒状、蜂窝状的无定形炭，也有排列规整的晶体炭。活性炭中除炭元素外，还包含两类掺和物：一类是化学结合的元素，主要是氧和氢，这些元素是由于未完全炭化而残留在炭中，或者在活化过程中，外来的非炭元素与活性炭表面化学结合，如用水蒸气活化时，活性炭表面被氧化或水蒸气氧化；另一类掺和物是灰分，它是活性炭的无机部分；灰分在活性炭中易降低活性炭的质量品质。
活性炭广泛用于石化、化工、食品制药及电力行业，如在火力发电厂、大型炼钢厂、石化炼油厂以及垃圾发电中，活性炭均发挥了不可替代的作用。居民生活中，活性炭可用于城市污水处理、饮用水及工业用水过滤处理等。在实际中，应用较广的是粉状活性炭及柱状活性炭，其中粉状活性炭使用时会造成二次污染、且其强度低、耐用性差、甚至会堵塞管道出入口等，在用于成品净化时，还会粘在成品上，不易分离；而柱状活性炭通常呈块状，粉磨后，其强度将会显著降低，往往达不到理想的效果，而且使用的时间短，会堵塞管口，用后还会造成第二次污染。
发明内容
本发明所要解决的技术问题是：提供一种球形活性炭，提高强度、耐用性长，避免二次污染。
为了解决上述技术问题，本发明采用的技术方案为：提供一种球形活性炭，所述球形活性炭通过有机粘合剂及粉状活性炭粘合而成。
为解决上述问题，本发明还提供一种球形活性炭的制备方法，所述球形活性炭通过有机粘合剂及粉状活性炭粘合而成。
本发明的有益效果在于：区别于现有技术，本发明通过将粉状活性炭与有机粘合剂进行粘合成球形后，放大孔径，增强吸附脱色效果。
具体实施方式
为详细说明本发明的技术内容、所实现目的及效果，以下结合实施方式予以说明。

本发明所述的球形活性炭可用于冶炼行业脱硫脱氯、净水行业中进行污水处理净化，或在火力发电厂、大型炼钢厂、石化炼油厂及垃圾发电的工作流程中进行脱硫脱氯，效果显著，而且不会造成二次污染，并可再生。
对应地，本发明还提供一种球形活性炭的制备方法，所述球形活性炭通过有机粘合剂及粉状活性炭粘合而成。
具体地，所述有机粘合剂包括：
甲基纤维素，含量占球形活性炭的5％～10％；
竹油，含量占球形活性炭的10％；
地瓜粉，含量占球形活性炭的5％～15％；
