Description

一种工业废气的处理方法
技术领域
本发明属于环境保护领域,尤其是涉及一种工业废气的处理方法。
背景技术
随着工业化进程的推进,我国的制造业获得了飞速发展,但我国的工业化发展还处在初级阶段,相当多企业的生产属于粗放和重污染型,如厂矿、医药、化工、冶炼、等生产过程中产生了大量的废气,上述废气中除了含有大量的烟尘固态粒子,还含有严重影响人体健康的重金属离子和大分子有机物,如果环境保护的技术和监管措施的不到位,上述废气排放到大气中,将会给人类和生态环境带来严重灾难,所以必须对工业废气进行严格的处理,目前废气排放处理方法主要有物理法、化学法、生物法或几种方法联用。其中吸附法是最常见的物理方法,吸附法是利用表面具有多孔的一些固体作为吸附剂,当废气与吸附剂接触时,废气中的一种或数种污染物被吸附在固体表面从而达到净化的目的。吸附法的应用范围比较广泛,没有专一选择性。但目前的吸附材料存在吸附不彻底,制备复杂,成本高的问题,严重制约了环保进程的发展。
发明内容
为了解决上述技术问题,本发明提供了一种工业废气的处理方法,具有吸附效果好,成本低,制备简单的优点。
本发明完整的技术方案包括:
一种工业废气的处理方法,其特征在于:
(1)准备复合吸附材料的原料,所述的复合吸附材料原料包括载体,功能成分和催化成分,其中载体按重量份计包括:膨润土与硅藻土的混合物8-10份,活性炭2-6份,沸石3-5份,凹凸棒石1-2份,此外还包括木屑、锯末、农作物秸秆的混合物40-50份,CMC1-2份,所述的膨润土与硅藻土混合物的粒径为0.1-0.2mm,活性炭的粒径为0.4-0.6mm,沸石、凹凸棒石的粒径为0.5-1mm,所述木屑、锯末、农作物秸秆的混合物粒径为0.2-0.5mm;功能成分按重量份包括:硫酸亚铁1.5-2份,高锰酸钾1-3份,硫酸钾/氯化镁中的一种或两种共计1-2份;所述功能成分中各原料的粒度为0.1mm;催化成分按重量份包括:纳米水和氧化铁0.5-1份,纳米二氧化钛0.5-1份;所述催化成分中纳米水和氧化铁和纳米二氧化钛的粒度为50-200nm;所述的复合吸附材料中的各成分重量比为,载体:功能成分:催化成分=(10-15):(2-6):(0.1-0.2),
(2)复合吸附材料的制备:选取载体中所述重量份的硅藻土和硅藻土混合物送入球磨机,按球料比(10-15):1球磨2-10小时后取出,过筛后备用,选取载体中所述重量份的活性炭按球料比(10-15):1球磨3-5小时后取出,过筛后备用,选取载体中所述重量份的沸石、凹凸棒石,首先粗碎成3-6mm的颗粒,随后送入球磨机,选择氧化锆磨球,球料比(10-15):1,并加入占磨料总质量0.1%的稀硫酸进行球磨1-2小时后取出,静置1小时后过筛;选取载体中所述重量份的木屑、锯末、农作物秸秆的混合物,在100-120℃下烘干2h,送入球磨机,球料比(10-15):1球磨2-4小时后取出,过筛后备用;选取功能成分中所述重量份的各组分混合,加入去离子水,用稀硫酸调PH值至4.5-6.5得到溶液;选取催化成分中所述重量份的各组分混合,加入去离子水,磁力搅拌30分钟得到悬浮液;按载体:功能成分:催化成分=(10-15):(2-6):(0.1-0.2)的重量比选择各成分,将催化成分的悬浮液加入功能成分溶液中,加去离子水稀释,依次加入载体的各组分,在60-80℃下搅拌,成为含水量40%-60%的浆料,将所述浆料静置8-10小时后烘干;
(3)将烘干后的复合吸附材料进行破碎筛分,分别得到80-120目,140-180目,200-240目的复合吸附材料,并分别装入前端带孔的管道中;
(4)将上述管道接入废气排放管道中,进行废气处理。
本发明相对于现有技术的优点为:在载体组分中,选择价格低廉且容易获取的木屑、锯末、农作物秸秆作为主要组分,并且结合其他的常见多孔材料配合CMC形成的交联结构,显著增加了载体强度,并且各组分的粒度的合理设置,形成孔径多级分布的多孔骨料,具有很强的烟尘和离子吸附能力,可以对废气中的烟尘、重金属和大分子有机物进行稳定吸附,显著降低了污染,既保证了良好的吸附效果,又兼顾了原材料价格,降低了生产成本,功能成分和催化成分可以起到氧化、增强反应速度和活性,稳定重金属离子,对大分子有机物进行分解,避免了吸附后的有害组分再次浸出,同时能够脱除臭味,避免对环境造成危害。
