Description

一种褐煤成型的生产方法 技术领域
本发明涉及褐煤的加工利用领域，尤其是涉及指一种采用冷压成型技术把褐煤生产成型煤或型焦的方法。
背景技术
褐煤是低变质煤种，单位热值低，孔隙发达，水分高、挥发分高，冷强度、热强度都很低。为了提高褐煤的利用价值和利用范围，国内外褐煤企热衷于研发褐煤干燥后成型的技术，也研发了各种粘结剂，但都效果不好，主要原因是褐煤粘结性很弱，且成型后褐煤颗粒会吸收空气中的水份而膨胀，短时间型煤就散开不成型，无法运用。有些国家开发了热压成型技术，设备投资和生产成本非常高，环保污染大，难以推广运用。
发明内容
针对现有技术存在的问题，本发明提供一种褐煤成型的生产方法。该生产方法采用冷压成型，把低热值强度弱运用范围小的褐煤原煤转化为高热值、高强度运用范围广的成品型煤或型焦。该方法涉及的设备投资低，生产成本低，环保代价小，易于批量生产。
为实现上述目的，本发明技术方案为：
一种褐煤成型的生产方法，其特征在于：该生产方法的具体实施如下：
①把褐煤原煤进行干燥和热解，热解后的产物包括煤气、煤焦油和褐煤半焦； ②把热解所得的煤气收集起来，并再利用作为原煤干燥和热解的燃料；③把热解所得的煤焦油收集起来，并部分利用作为阻水粘结剂的原料，剩余部分可作为其它的利用；④把热解所得的固态产物褐煤半焦，破碎成粒径低于3毫米的半焦粉粒，与阻水粘结剂按比例均匀混合。所述阻水粘结剂重量占要生产的型煤或型焦总重量的百分之二十以下，其余的为半焦粉粒；⑤半焦粉粒与阻水粘结剂均匀混合后，进行机械压型，即可制成型煤或型焦。
进一步，所述阻水粘结剂按以下步骤配制：将高分子纤维素和水混合搅拌，到高分子纤维素完全溶解；再加入煤焦油，搅拌均匀即可。所述高分子纤维素的重量占要生产的型煤或型焦总重量的万分之五以上，所述水的重量占要生产的型煤或型焦总重量的百分之八以上，所述煤焦油占要生产的型煤或型焦总重量的千分之五以上；
进一步，所述煤焦油占要生产的型煤或型焦总重量的1—2%。
进一步，所述高分子纤维素粘度单位大于800mpa·s。
进一步，所述阻水粘结剂重量占要生产的型煤或型焦总重量的8%-15%。
进一步，在阻水粘结剂配制中，在加煤焦油的同时加入液体沥青，所述液体沥青重量占要生产的型煤或型焦总重量的千分之五以上。
上述技术方案的有益之处在于：
经本发明干燥和热解产生的各产物（煤气、煤焦油和褐煤半焦）均得到充分利用，经济性好。褐煤成型过程中所采用的阻水粘结剂的主要原料（煤焦油、水和高分子纤维素）来源广泛，特别是其中的主要成份煤焦油，其来源于原煤干燥和热解直接产生的产物，成本低，且纯有机成分，环保污染小，阻水粘结剂产生的防水效果好。本发明褐煤成型采用冷压成型技术，不需要高温高压的工作条件，设备投资小，生产成本低，可以大批量生产。经本发明干燥和热解产生的型煤或型焦的单位热值比原煤的单位热值大幅度增长，显著提升型煤或型焦的利用价值和利用空间。
附图说明
此处所说明的附图用来提供对本发明的进一步理解，构成本发明的一部分，本发明的示意性实施例及其说明用于解释本发明，并不构成对本发明的不当限定。在附图中：
图1是本发明褐煤成型生产方法的工艺流程示意图。
具体实施方式
为了使本发明所要解决的技术问题、技术方案及有益效果更加清楚、明白，以下结合附图和实施例，对本发明进行进一步详细说明。应当理解，此处所描述的具体实施例仅用以解释本发明，并不用于限定本发明。
如图1所示的一种褐煤成型的生产方法，其特征在于：该生产方法的具体实施如下：
①把褐煤原煤进行干燥和热解，热解后的产物包括煤气、煤焦油和褐煤半焦；
②把热解所得的煤气收集起来，并再利用作为原煤干燥和热解的燃料；
③把热解所得的煤焦油收集起来，并部分利用作为阻水粘结剂的原料，剩余部分可作为其它的利用。
所述阻水粘结剂按以下步骤配制：将高分子纤维素和水混合搅拌，到高分子纤维素完全溶解；再加入煤焦油，搅拌均匀即可。所述高分子纤维素的重量占要生产的型煤或型焦总重量的万分之五以上，最佳的，所述高分子纤维素粘度单位大于800mpa·s；所述水的重量占要生产的型煤或型焦总重量的百分之八以上；所述煤焦油占要生产的型煤或型焦总重量的千分之五以上，最佳的，所述煤焦油占要生产的型煤或型焦总重量的1—2%。
④把热解所得的固态产物褐煤半焦，破碎成粒径低于3毫米的半焦粉粒，此时的褐半焦粉粒本身吸水和膨胀的幅度比原煤大大降低了。调节热解的温度和时间可以调节煤半焦的挥发份，以满足最后型煤或型焦对挥发份的要求。型煤或型焦对煤半焦的要求是挥发份最好低于35%，型煤或型焦对煤半焦的要求是挥发份越低越好，挥发份越低，型煤或型焦的发热量越高，但热解程度也要求越高，生产成本越高。将上述粒径低于3毫米的半焦粉粒与阻水粘结剂按比例均匀混合，所述阻水粘结剂重量占要生产的型煤或型焦总重量的百分之二十以下，其余的为半焦粉粒。最佳的，所述阻水粘结剂重量占要生产的型煤或型焦总重量的8%-15%。
⑤半焦粉粒与阻水粘结剂均匀混合后，用普通成型机械，如对辊压球机、平模成型机、环模成型机等均可，进行机械压型，即可制成型煤或型焦。
⑥可在压型后再次烘干或干馏，进一步提高其成型后的强度和单位热量。为了进一步提高型煤或型焦的冷强度和热强度，可在步骤③的阻水粘结剂配制中，在加煤焦油的同时加入液体沥青，所述液体沥青重量占要生产的型煤或型焦总重量的千分之五以上，最佳的，所述液体沥青采用煤沥青。当然，在步骤③的阻水粘结剂配制中，高分子纤维素、煤焦油及煤沥青的加入量越大，阻水粘结剂的粘接性及阻水性越好，但生产成本随之攀高。
上述说明示出并描述了本发明的优选实施例，如前所述，应当理解本发明并非局限于本文所披露的形式，不应看作是对其他实施例的排除，而可用于各种其他组合、修改和环境，并能够在本文所述发明构想范围内，通过上述教导或相关领域的技术或知识进行改动。而本领域人员所进行的改动和变化不脱离本发明的精神和范围，则都应在本发明所附权利要求的保护范围内。
