一种分散均匀的活性炭硅藻土空气净化颗粒及其制备方法
技术领域
本发明涉及一种脱硫活性炭及其制备方法，特别是一种分散均匀的活性炭硅藻土空气净化颗粒及其制备方法。
背景技术
目前空气中的污染物主要是工业燃料燃烧产生的气体、汽车尾气、生产中产生的有毒有害气体。水污染主要是工业生产排放的污水里含有大量有毒物质，还有人们生活中的污水产生很多有害物质。人们生活中也有很多时候需要脱除毒素，比如空调过滤网上有很多细菌、毒素，新装修的间有甲醛等有害物质，都需要脱除毒素。目前都脱除毒素经常用到吸附剂，主要有硅胶、活性纳米碳、活性炭、分子筛等，另外还有针对某种组分选择性吸附而研制的吸附材料。但是这些吸附剂大多吸附能力有限，需要针对不同的要求研究不同的吸附剂，发挥最好的作用。同时，寻找新的原料，以增强吸附效果，节约成本。
高比表面积活性炭具有多孔结构，能吸附各种有机物和无机物，具有吸附容量大、吸附速度快的特点，是一种优质的高效吸附剂，广泛用于食品工业、化学工业和环境保护等各个领域。
硅藻土具有孔隙度大、吸收性强、化学性质稳定、耐磨、耐热等特点，能够有效吸附空气中的有毒有害气体。
