Description
技术领域
本发明涉及工业有机废气治理领域,更具体地说,本发明涉及一种用于VOC治理的活性催化的新材料及其制备方法。
背景技术
VOC是挥发性有机气体的总称,含苯、甲醛等数百种危害气体,其中数十种为致癌物或致突变物,有些长期接触导致白血病、流产、胎儿畸形和生长发育迟缓等,在空气中与光作用,形成其它颗粒进一步污染环境。
中国非常重视VOC的治理,相关国家法规及地方标准已陆续出台,如国务院2013.9.10下发的国发[2013]37号文件;天津市于2014.8.1出台的DB12/524-2014《工业企业挥发性有机物排放控制标准》;河北省于2016.2.24出台的DB13/2022-2016《工业企业挥发性有机物排放控制标准》等。各地方细则也相继出台,如河南郑州、河北秦皇岛等城市。我国虽然急于大力治理VOC,但VOC治理的技术却不成熟,特别是对于大风量的VOC治理难度和成本依然很大。
发明内容
本发明所要解决的问题是提供一种用于VOC治理的活性催化的新材料及其制备方法,通过将吸附材料、多种活性催化剂、吸附材料载体、粘合剂、水按一定的比例复合而成。该材料具备在一定的压力下,常温下普通气体可以自由穿透,但对VOC气体分子有较强吸附作用;同时具备增强VOC气体分子被催化氧化的催化性能或利用吸附在材料上的VOC分子来消除O3。
为了实现上述目的,本发明采取的技术方案为:一种用于VOC治理的活性催化的新材料及其制备方法,其特征在于:所述一种用于VOC治理的活性催化的新材料及其制备方法,由吸附材料、活性催化剂、吸附材料载体、粘合剂、水复合而成,同时具备在一定的压力下,常温下普通气体可以自由穿透,但对VOC气体分子有较强吸附作用;同时具备提高VOC气体分子被催化氧化的催化性能或利用吸附在材料上的VOC分子来消除O3。消除O3的方法如下:利用材料对VOC分子吸附性能,先吸附部分VOC分子在材料上,使材料的吸附处于半饱和状态,再穿过的O3分子在材料的催化作用下会被直接消除,而穿过的VOC分子则被吸附在材料上,只要O3分子与VOC分子维持一定的平衡,两种污染源就会以材料作为载体进行反应,从而达到催化与净化的目的。相关进一步的应用说明见本发明的发明人在其它应用发明。
吸附材料是由具备在一定的压力下,常温下普通气体可以自由穿透,但对VOC气体分子有较强吸附作用的材料构成,可以是活性炭、活性炭纤维、沸石、分子筛等材料的一种或多种组合,本发明为叙述方便,采用活性炭来说明,不代表本发明的吸附材料仅限于活性炭;
活性催化剂是能提高O3和(或)OH-自由基对VOC气体分子氧化性及氧化速度的各种催化剂的一种或多种组合,如锰系催化剂里的二氧化锰、硫酸锰等。本发明为叙述方便,采用二氧化锰来说明,不代表本发明的吸附材料仅限于二氧化锰;
吸附材料载体是为把吸附材料、活性催化剂、粘合剂、水成型并复合一起的载体,可以是陶瓷或硬质纤维材料等。本发明为叙述方便,采用硬质纤维材料来说明,不代表本发明的吸附材料仅限于硬质纤维材料;
粘合剂为普通工业用粘合剂,主要用途是使吸附材料、活性催化剂、吸附材料载体混合均匀并协助成型,使产品具有一定的强度;
该用于VOC治理的活性催化的新材料的制备方法为:将上述吸附材料、活性催化剂、吸附材料载体、粘合剂、水按一定比例混合后成型并硬化。一定比例可以是满足成型、吸附、催化功能的任意比例,本发明为为叙述方便,采用吸附材料、活性催化剂、吸附材料载体的比例为30∶10∶59∶1∶100来说明,不代表本发明的材料比例为30∶10∶59∶1∶100。
有益效果:该用于VOC治理的活性催化的新材料及其制备方法通过将吸附材料、多种活性催化剂、吸附材料载体、粘合剂、水按一定的比例复合而成。该材料具备在一定的压力下,常温下普通气体可以自由穿透,但对VOC气体分子有较强吸附作用;同时具备增强VOC气体分子被催化氧化的催化性能或利用吸附在材料上的VOC分子来消除O3。
