Abstract
本发明涉及用含有至少50%元素硅的细粒材料生产非晶形硅石的方法,它是把含硅材料送入用油燃烧器或气体燃烧器加热的燃烧反应器中,并从燃烧反应器出口后面回收非晶形硅石。至少有一部分含硅材料是以水成淤浆的方式被送入燃烧反应器。本发明还涉及生产非晶形硅石的装置。
Description
发明领域
本发明涉及由含硅材料与空气、富氧空气或氧进行火焰燃烧，从硅和含硅材料生产非晶形硅石的方法。本发明还涉及生产非晶形硅石的装置。
背景技术
非晶形硅石颗粒小、表面积很大，现在的生产方法主要是将挥发性硅化合物，特别是四氯化硅与含氧气体在火焰中进行反应。被称为“雾化硅石”的该产品具有多种用途，特别是用作塑料和橡胶的填充剂。还知道类似的非晶形硅石产品可在等离子炉和电炉中生产，反应物是石英和碳或者硅石和石英。这些产品很贵，未见多用。
从欧洲专利EP-B-151490和美国专利4,755,368中知道硅的火焰燃烧方法，它是将细粒的硅例如空气或氧的气体中流化后送入反应器，在火焰中燃烧硅来制造SiO2微粒。
从挪威专利304366还知道一种用细粒的含硅材料生产非晶形硅石的方法，它是用含氧流化气体以流化方式，把细粒的硅送入燃烧反应器中，再加入补充的含氧气体，使细粒的硅燃烧成SiO2，而无需再加别的热能。
已知的用硅粉燃烧成非晶形SiO2的方法的缺点是难于均匀一致地生产。相信其主要原因是当硅粉在气体中流化时，很难均匀一致地向反应器中供料。另外，从挪威专利304355可以看出，该方法生产出的SiO2只能得到20m2/g的比表面积，而对很多用途来说，所要求的硅石的比表面积要高得多，达80m2/g或更高。
发明内容
本发明的目的是要提供出一种将含硅材料燃烧成SiO2的方法和装置，它能将硅非常均匀非常稳定地送入燃烧反应器，它所制得的非晶形硅石具有高得惊人的比表面积。
因此本发明是涉及用含有至少50％元素硅的细粒材料生产非晶形硅石的方法，它是把含硅材料送入用油燃烧器或气体燃烧器的热的燃烧反应器中，并从燃烧反应器出口后面回收非晶形硅石，该方法的特征在于，至少有一部分含硅材料是以水成淤浆的方式送入燃烧反应器的。
按照一个优选的实施方案，硅是以水成淤浆的方式被送入燃烧反应器中，该淤浆中以重量计含有20％～80％的含硅材料，优选含有以重量计40％～60％的含硅材料。
按照另一个优选的实施方案，在含有含硅材料的水成淤浆中还加入粘度调节剂、如无机酸或有机分散剂。
为了改进所生产的无晶形硅石的表面，可往水成淤浆中加入表面改性剂，例如铝盐，优选为硫酸铝。
按照又一个实施方案，可在燃烧反应器的出口区域加入水以使非晶形硅石骤冷。
令人惊喜地发现，借助于以水成淤浆的方式送入硅料可使反应室操作处于平衡状态，同时还能使生产出的非晶形硅石具有惊人高的比表面积达100m2/g以上。
作为含硅材料，可使用含有元素硅至少50％的细粒材料。这些材料的例子有：细粒状的冶金级硅；细粒状的高纯度硅；雾化硅；电子用和太阳能电池用硅片的锯屑；粉碎硅时所得到的滤粉；生产有机卤素硅烷和无机硅烷的反应器中的残留内。
本发明还涉及用含有以重量计至少50％元素硅的细粒材料生产无晶形硅石的装置，该装置包括一个加长的反应室，反应室一端有一个由燃烧器或气体燃烧器，在反应室侧壁上至少设有一个供应含硅材料水成淤浆的孔、一个无晶形硅石产品的出口孔；以及收集无晶形硅石的设施。
该反应室优选设有一个供应空气、富氧空气或氧的入口孔。
附图简述
图1示出本发明的装置的断面图。
图1中示出圆柱形的燃烧反应器1。燃烧反应器1包括有外部钢筒2，其内衬有耐火衬套3。在燃烧反应器1的一端装有一个油燃烧器或气体燃烧器4。燃烧反应器1的另一端设有一个出口孔。在钢筒2外面装有供冷却空气循环用的冷却套5。冷却套5上设有一个入口孔6。反应室1上还设有一个入口孔7，以供输入含硅材料的水成淤浆。
冷却空气通过入口孔6送入冷却套5，离开冷却套5后进入小室8，小室8借助于出口9与过滤器或类似物相连结，以收集生产出的非晶形硅石。还设有一个入口孔10，以便向反应器1输入空气、富氧空气或氧。
开始生产时，反应器1首先用油燃烧器或气体燃烧器4加热。随后开始输入硅，通过入口孔7输入含硅的水成淤浆并通过孔10输入空气、富氧空气或氧。进入反应器的硅粒将着火并在通过反应室1过程中被烧制成非晶形硅石。
实施例1
将从粉碎冶金级硅的工厂收集来的硅粉与水混合成含有以重量计60％硅的淤浆。该淤浆在如图1的反应器被预热到约1550℃时，从入口端送入反应室。淤浆是被泵入反应器的入口孔7的，流量率为0.2kg/min，同时还流入500l/min的氧。生产出的无晶形硅石则在与小室8的出口孔9相连结的过滤单元中被收集起来。
该非晶形硅石的比表面积按照DIN 66132(BET单点测量法)进行了测量。其比表面积为114.2m2/g。
为了测量该非晶形硅石的晶状硅石含量，使用了菲力浦PW1710 X-射线衍射机(它在X-射线管中有铜阳极)进行检验，结果没有发现晶状硅石。
实施例2
重复实施例1的试验，不同的只是送入反应器的淤浆量改为0.4kg/min。所生产出的非晶形硅石的比表面积为213.6m2/g。
实施例3
重复实施例1的试验，不同的只是使用含硅50重量％的淤浆。所生产出的非晶形硅石和比表面积为117.9m2/g。
实施例4
重复实施例1的试验，不同的只是所用的含硅材料是金刚石切割太阳能电池用硅片的切屑，该切屑已用球磨机研磨过15分钟。所生产出的非晶形硅石的比表面积为103.2m2/g。
实施例1～4显示出，按照本发明的方法所得到的非晶形硅石，比挪威专利304366所生产的非晶形硅石的比表面积高得多。
