Description

一种煤炭的阻水粘结剂 技术领域
本发明涉及煤炭加工利用领域，尤其是涉及一种适用于各煤种的阻水粘结剂。
背景技术
现有的煤炭阻水粘结剂主要有两大类，一类是无机盐类，如硅酸盐、膨润土、磷酸二氢铝等，添加到煤炭里会增加灰份，降低煤炭的单位发热量，而且多呈碱性，用到褐煤或其他低变质煤里会与低变质煤里的腐殖酸起不良反应，影响煤碳的强度并降低挥发份和单位发热量；另一类是有机类，如木质素、纤维素，聚乙烯醇或淀粉糊化物，这类物质添加成本高，有粘结作用但阻水效果不好。
发明内容
针对现有技术中存在的上述问题，发明目的是提供一种煤炭的阻水粘结剂。该阻水粘结剂配制方法简单、材料成本和生产成本低，普遍适用于各煤种。
本发明解决其技术问题所采取的技术方案是：
一种煤炭的阻水粘结剂，该阻水粘结剂是由高分子纤维素，不溶或微溶于水的油类和水按以下的重量百分比配制而成；所述高分子纤维素为要处理的煤炭总重量的万分之五以上，所述不溶或微溶于水的油类为要处理的煤炭总重量的千分之五以上，余量为水。
进一步，所述阻水粘结剂的总重量为要处理的煤炭总重量的5～10%。
进一步，阻水粘结剂按以下步骤配制：以要处理的煤炭总重量的万分之五以上比例的高分子纤维素与水混合搅拌到高分子纤维素完全溶解；再加入要处理的煤炭总重量的千分之五以上比例的难溶或微溶于水的油类，搅拌均匀即可。
进一步的，所述高分子纤维素的粘度单位大于800mPa.s。
进一步，高分子纤维素与水在50℃～60℃的水温下混合搅拌。
与现有技术相比，本发明的有益效果是：
本发明煤炭的阻水粘结剂采用不溶或微溶于水的油类，该油类具有粘度，也有防水性，通常要用大量的油才能在煤颗粒中分散开来，达到防水效果。本发明利用高分子纤维素来延长分子链，使油充分稀释于大量水溶液中，不分离不断层，用少量的油就可以均匀添加到大量的煤颗粒表面，以很小的成本即可达到阻水粘结的效果。本发明采用的油类来源广泛，可用石油产品，工业废油、食品废油（地沟油）、煤焦油等。尤其是利用上述方法把食品废油（地沟油）充分稀释，不仅有易于检测、观察其各种成分和特性，且依本发明技术方案制成阻水粘结剂，也是为食品废油（地沟油）的回收利用另辟一环保、节能的新途径。

具体实施方式
一种煤炭的阻水粘结剂，该作为煤炭提质专用的阻水粘结剂是由高分子纤维素，不溶或微溶于水的油类和水按以下的重量百分比配制而成的。所述高分子纤维素为要处理的煤炭总重量的万分之五以上，所述不溶或微溶于水的油类为要处理的煤炭总重量的千分之五以上，余量为水。阻水粘结剂中水量添加过多会增加要处理的煤炭水份或增加烘干负担。
上述阻水粘结剂的配制步骤及其应用如下：
一、以要处理的煤炭总重量的万分之五以上比例的高分子纤维素与水混合搅拌到高分子纤维素完全溶解。所述高分子纤维素的粘度单位应大于800mPa.s。高分子纤维素与水最好在50℃～60℃的水温下混合搅拌到纤维素完全溶解。所述高分子纤维素用量大于要处理的煤炭总重量的万分之五即可，用量越大，粘结效果越好，但成本越高。
二、再加入要处理的煤炭总重量的千分之五以上比例的难溶或微溶于水的油类，搅拌均匀即可。所述难溶或微溶于水的油类来源广泛，可用石油产品，工业废油、食品废油（地沟油）、煤焦油等。难溶或微溶于水的油类添加量为要处理的煤炭总重量的千分之五以上就有效果，添加量越大，效果越好，但成本升高。
三、将上述制得的阻水粘结剂均匀地喷涂于要处理的煤炭表面，或与要处理的煤炭混合后用搅拌机充分搅拌。对于粉状要处理的煤炭，搅拌后可压型，可造粒，也可烘干，冷态或热态都会增加强度和防水效果。所述阻水粘结剂是以其总重量为要处理的煤炭总重量的5～10%比例添加到要处理的煤炭中的。
