Description

一种烟梗茶籽壳抗菌改性活性炭脱硫颗粒及其制备方法
技术领域
本发明涉及一种脱硫活性炭及其制备方法，特别是一种烟梗茶籽壳抗菌改性活性炭脱硫颗粒及其制备方法。
背景技术
烟梗主要成分为纤维素、木素、总糖，果胶等，这些都是含有大量C、H、O、S、N等元素的物质，所以在烟梗燃烧时有CO、CO2、SO2、NO2等污染物的排放，严重的威胁到了大气环境质量，所以烟梗废弃物并不适宜来直接燃烧来处理，也不适宜像秸秆那样还田做肥料。茶籽壳中含有茶皂素、茶籽多糖、茶籽蛋白等，它们都是化工、肥料、轻工、食品、饲料工业产品等的原料，茶籽壳还可制成糠醛、活性炭等 ，茶壳还是一种良好的食用菌培养基。研究表明，油茶皂素还有抑菌和抗氧化作用。
本发明将这两种原料废物利用，经过干燥粉碎，添加到活性炭中，制成颗粒，使得脱硫剂容易固定，安全无毒，吸附性能强，增强产品的刚性和强度，延长了活性炭的使用时间，降低了干法脱硫的成本。
发明内容
本发明的目的是提供一种烟梗茶籽壳抗菌改性活性炭脱硫颗粒及其制备方法。
为了实现本发明的目的，本发明通过以下方案实施：
一种烟梗茶籽壳抗菌改性活性炭脱硫颗粒，由下列重量份的原料制备制成：椰壳活性炭100-105、硅藻土35-40、烟梗28-33、茶籽壳20-24、十二烷基硫酸钠1-2、膨胀聚苯乙烯3-5、氢氧化钾2-3、α-烯基磺酸钠1-2、氯化锌2-3、羧甲基纤维素钠3-5、活性氧化铝6-8、石英粉3-5、吸附助剂4-6、水适量；
所述吸附助剂由以下重量份的原料制成：锆英粉8-11、鹿沼土2-3、氯化镁2-3、碳酸氢钠1.5-2.5、天然焦炭粉2-4、聚丙烯酰胺2-3.5、二氧化铈2-3、软木12-14、竹纤维10-13；制备方法是将软木、竹纤维在100℃-120℃条件下干燥1-1.5小时，粉碎成40-60目粉末，然后加入适量水与除鹿沼土之外的其余剩余成分搅拌均匀，形成泥状物，然后放入400℃-500℃的炭化炉中炭化2-3小时，取出冷却后粉碎成80-100目粉末，加入鹿沼土，用50%-60%的醋酸溶液浸泡1.5-2小时，过滤，取滤渣加1.5-2倍量的纯水研磨40-50分钟得浆料即可。
本发明所述一种烟梗茶籽壳抗菌改性活性炭脱硫颗粒，由以下具体步骤制成：
（1）将烟梗、茶籽壳在95℃-115℃的条件下烘烤1.5-2.5小时，粉碎成80-100目的干燥粉末与椰壳活性炭、硅藻土一同放入球磨机中球磨1.5-2.5小时，球磨后过150-200目筛，得到混合粉末待用；
（2）将氢氧化钾、氯化锌、羧甲基纤维素钠、活性氧化铝、石英粉中加入适量的水，不断搅拌制成浆料，然后加入除吸附助剂之外的其余剩余成分，加热至85℃-95℃，保温研磨1-1.5小时，得混合浆料待用；
（3）将混合粉末、混合浆料、吸附助剂相互搅拌均匀，然后浓缩干燥，送入造粒机中造粒即得。
本发明的有益效果是：本发明配方合理，将烟梗、茶籽壳废物利用，干燥粉碎后与活性炭混合，不仅增加了比表面积，而且具有抗菌效果；添加粘性物质，增加了活性炭的韧性以及强度，延长了使用寿命；本发明活性炭具有抗菌抑菌效果，脱硫效率高，适合工业干法脱硫，汽车尾气脱硫，日常空气净化。
