Description

一种蓝藻泥脱水用高通量、抗粘滤布及其制备方法
技术领域
本发明涉及滤布技术领域，尤其涉及一种蓝藻泥脱水用高通量、抗粘滤布及其制备方法。
背景技术
蓝藻是淡水湖泊水体富营养化之后产生的生态产物，由于这些年蓝藻的不断爆发，形成经常性大量水华的爆发情况，不仅破坏了健康平衡的水生生态***，使水体感官性状恶化，散发出难闻的气味，而且由于藻细胞腐败裂解后释放出了多种藻毒素而对人和动物的饮用水安全构成了严重的威胁。
目前，在蓝藻爆发期时，一般是通过打捞设备将蓝藻打捞，形成蓝藻泥，此时的蓝藻泥含水率一般在80-90％，然后将打捞的蓝藻泥通过压滤机压滤，使蓝藻泥中的进一步脱水，便于后续的处理。但由于蓝藻泥中富含大量的有机物质以及蓝藻细菌，使压滤机在压滤时，有机物质以及蓝藻细菌容易粘附在压滤机的滤布上，随着压滤机的不断压滤，滤布上粘附的有机物以及蓝藻细菌越来越多，一方面，容易堵塞滤布，造成压滤效果下降，另一方面，使滤布的清洗频率增加，不仅增加成本，还影响工作效率。
发明内容
有鉴于此，本发明的目的是提供一种蓝藻泥脱水用高通量、抗粘滤布及其制备方法，使压滤机在进行蓝藻泥脱水时，蓝藻泥能够快速被压滤，同时，减少有机物以及蓝藻细菌附着在滤布上，提升压滤效果，减少滤布的清洗次数。
本发明通过以下技术手段解决上述技术问题：
一种蓝藻泥脱水用高通量、抗粘滤布，所述滤布包括三层结构，所述滤布包括第一过滤层、第二过滤层和支撑层，所述第一过滤层由聚酯纤维和无机粉体通过熔融纺丝、挤压成网制备得到的无纺滤布，所述第二过滤层为聚醚砜纺丝滤布，所述支撑层为聚丙烯纤维化学改性得到的无纺滤布。
通过第一过滤层的设置，使蓝藻泥在压滤时，能够减小有机物及蓝藻的附着，提升滤布的抗粘性，通过第二过滤层的设置，提高滤布的孔隙率，提高的滤布的通量，从而提升滤布的过滤效率，通过支撑层的设置，增加整个滤布压滤时的韧性、耐磨性和支撑强度，延长滤布的使用寿命。
进一步，所述聚酯纤维为短纤纤维，长度为2-5m，直径为10-120um，聚丙烯纤维为短纤纤维，直径为2-30um。
进一步，所述无机粉体为光催化材料与抗静电剂复合形成，所述光催化剂为纳米二氧化钛、氧化锌、纳米氧化硅中的一种或多种，所述抗静电剂为季铵盐、聚乙二醇、硫酸酯、乙氧基化烷基胺、甘油一硬脂酸酯、乙氧基月桂酷胺中的一种或多种。
通过将光催化材料与抗静电剂复合，再添加到聚酯纤维中，使第一过滤层不仅能够抗粘，还能够形成更多的孔隙，提升第一过滤层的通量，配合第二过滤层，进一步提高滤布的通量。
进一步，所述无机粉体的制备包括以下步骤：
S1纳米二氧化钛改性：将纳米二氧化钛置于去离子水中，加入钛酸酯偶联剂，超声1-5H，抽滤、洗涤、干燥，得到疏水改性的纳米二氧化钛；
S2：中间体的制备：将S1步骤处理的纳米二氧化钛置于聚乙二醇600溶液中，搅拌1-3H，搅拌完成后，加入消泡剂，继续搅拌30-60min，转入水浴摇床中，加入柠檬酸钠，于30-50℃的条件下，震荡10-24H，得到凝胶中间体；
S3无机粉体的制备：将S2步骤中的凝胶中间体于氮气氛围下，梯度升温至200-240℃，得到固态中间体，将固态中间体研磨成细粉，将细粉与乙氧基月桂酷胺溶液混合，于50-60℃的条件下加入钛酸酯偶联剂，继续研磨，得到无机粉体。
纳米二氧化钛是一种填充剂，同时也是一种光催化材料，通过用钛酸酯偶联剂将纳米二氧化钛表面改性，使纳米二氧化钛表面呈疏水性。聚乙二醇600是一种溶液，具有优良的润滑性、保湿性、分散性、粘接性和稳定性，可作为抗静电剂使用，通过将表面改性的纳米二氧化钛与聚乙二醇600混合，使纳米二氧化钛与聚乙二醇600交联，再通过加入乳化剂、消泡剂和柠檬酸钠，形成凝胶，将纳米二氧化钛均匀分散在聚乙二醇凝胶的空间网状结构内，并由于聚乙二醇的作用，增大了网状结构内的孔径。
聚乙二醇在惰性气体的环境下，具有良好的稳定性，通过梯度升温，将凝胶中的水分蒸发，使凝胶固体中形成若干孔道，将凝胶固体粉碎，再与高分子抗静电剂乙氧基月桂酷胺机械热交联，使高分子抗静电剂交联在凝胶固体的表面和孔道内，得到内外均具有抗粘性的无机粉体。
通过先将抗静电剂与纳米二氧化钛复合，使无机粉体添加到聚酯纤维中时，能够分散的更均匀，且稳定性更好，在加强聚酯纤维的物理性能时，能够提高聚酯纤维的孔隙率，进而提高通量。
进一步，所述S3步骤中细粉的粒径为120-200目，所述无机粉体的粒径为600-1000目。
通过控制中间细粉的粒径，使高分子抗静电剂能够更好的附着在中间体上。
进一步，所述S3步骤中，梯度升温过程中，以5-10℃/min升高温度。
通过控制升温速率，能够加强凝胶结构的稳固性，使凝胶的孔道更均匀。
本发明还公开了一种蓝藻泥脱水用高通量、抗粘滤布的制备方法，包括以下步骤：
A1第一过滤层的制备：将聚酯径树脂加热至熔融状态，加入无机粉体，搅拌均匀，经过过滤后，通过计量泵转入第一熔喷喷头，第一熔喷喷头将熔流体喷射在成网装置上，形成单丝短纤，单丝短纤通过不断折叠，形成纤维网，将纤维网置于紫外光下照射，得到第一过滤层；
A2支撑层的制备：将聚丙烯树脂加热至熔融状态，加入防老剂，于190-200℃的条件下，继续搅拌5-10min，通过计量泵转入第二熔喷喷头，第二熔喷喷头将熔流体喷射在成网装置上，通过第二控制喷头的喷射速率与时间，形成聚丙烯短纤，并铺设在成网装置上，形成支撑层；
A3第二过滤层的制备：将聚醚砜树脂加热至熔融状态，通过静电纺丝，得到聚醚砜过滤层；
A4：将第二过滤层置于支撑层上，将第一过滤层置于第二过滤层上，在支撑层和第一过滤层余热的作用下，采用针刺加固法，进行加固，再通过后整理，得到滤布。
通过将聚酯径树脂与无机粉体熔融，再通过熔喷喷头与成网装置配合，形成无纺聚酯纤维网，再通过紫外光照射，通过控制紫外光照射的时间，二氧化钛在紫外光作用下，发生光催化反应，将聚乙二醇孔道内的聚酯径温热树脂分解，提高聚酯纤维的孔隙率，提高第一过滤层的过滤效果。支撑层采用聚丙烯树脂通过加入防老剂改性，使得到的支撑层不仅具有良好的耐磨性、弹性、韧性和耐光性，通过将第一过滤层、第二过滤层和支撑层依次通过热黏合，形成滤布，再通过针刺加固法，一方面加强第一过滤层、第二过滤层和支撑层的结合强度，另一方面，进一步增加了无纺滤布的孔隙，且孔隙无规则，与具有耐酸碱性强，化学稳定性和热稳定性高，耐磨性和抗疲劳性强，使用寿命长的聚醚砜过滤层复合，整体提高了滤布的通量、耐磨性、韧性和抗粘性。
进一步，所述A1步骤中，单丝短纤的折叠方式为往返折叠与斜向45°折叠交错进行，所述第一熔喷喷头的喷射速率为180-260m/sec。
通过交错折叠，使第一过滤层的孔隙率得到控制，配合聚酯纤维的孔隙，提升第一过滤层的通量。
进一步，所述A1步骤中，紫外线的波长为180-380nm。
进一步，所述A2步骤中，第二熔喷喷头的喷射速率为60-120m/sec，间隔时间为0.1-0.5s。
本发明的一种蓝藻泥脱水用高通量、抗粘滤布及其制备方法，通过在制备第一过滤层时，采用聚酯纤维与二氧化钛、聚乙二醇以及乙氧基月桂酷胺复合，并通过熔喷喷头在形成纤维网时，采用紫外线照射，使聚酯纤维形成的无纺滤布的纤维丝上成型有孔隙，但通过二氧化钛的作用，并不会影响纤维丝的物理性能，得到具有多孔结构以及抗粘性能的第一过滤层，再与纺丝形成的聚醚砜过滤层配合以及聚丙烯纤维形成的支撑层相互配合，通过针刺加固法将三层加固后得到的高通量滤布，经测试，滤布的通量在压滤蓝藻泥时，通量为175-200L/m2·h，比同规格的普通聚酯纤维滤布提高了30-45％。通过在第一过滤层制备时添加的二氧化钛、聚乙二醇和乙氧基月桂酷胺，使第一过滤层具有良好的抗粘性以及自洁性，从而使整个滤布具有高通量和抗粘以及自洁的特性，加快了蓝藻泥的压滤效率，降低了滤布的清洗频率。
