Description

喷射物料的方法和装置
本发明涉及一种喷射物料的方法，在该方法中用燃料气体产生火焰，并将至少两种不同的组分引入到火焰内，使它们互相化合而形成一种含有至少两种组分的物料。
另外，本发明涉及喷射物料的装置，该装置具有供应燃料气体使之产生火焰的设施和将至少两种不同组分引入到火焰内使之互相化合而形成一种含有至少两种组分的物料的设施，该物料能被火焰喷射到所希望的目标上。
已知可用火焰喷射装置来喷射固态物质。在该方法中，要被喷射的固态物质以固态颗粒的形态被输送到火焰喷枪内，然后被火焰喷射装置喷射到所希望的目标上。但当颗粒尺寸变小时火焰喷射装置容易被弄脏和堵塞。这样，即使采用火焰喷射装置也难于喷射例如尺寸小于20微米的颗粒，并且火焰喷射装置容易被堵塞，其构造较昂贵。另外，要被喷射的固态物质在火焰喷射期间呈几种不同的相，部分为蒸气，部分为熔化物质和局部熔化的物质。当物质冷却时，最终的结果是不均匀。
美国专利3,883,336提出一种装置，其中用氧气作为载体气体将四氯化硅的蒸气供给到火焰喷枪内。另外，所说公报公开将一种气悬体从外面被喷射到火焰喷枪的火焰内，以制造玻璃。但气悬体的生产需要复杂的装备，另外，气悬体的形成要求液体的粘度在一定的范围内，这一点限制了所用物料的化合。再者，用这方法产生的颗粒尺寸较大，即在微米的数量级内。
芬兰专利98832提出一种喷射物料的方法和装置，在该方法中要被喷射的液态物质被引到用燃料气体生成的火焰中，并被基本上在火焰附近的气体雾化，使雾化和火焰生成在同一装置内进行。采用所说方法，能够简单而便宜地生产出纳米大小的颗粒。但该解决方案不能用来生产出含有几种组分而组分比例能被控制的物料如多组分玻璃。
生产多组分玻璃的一种用途是生产活性纤维。在生产活性纤维时，玻璃物料必须用稀土金属如铒搀杂。铒通常不以液态供售，其蒸气压力相当低，使活性纤维能用传统的纤维生产方法生产而不需对过程作广泛而费钱的修改。为此理由，一般采用的生产活性纤维的方法是先制造一个基本上含有不定形二氧化硅的多孔的雏形，将该雏形浸没在含有铒的液体内。在浸渍数小时后，使雏形干燥并烧结，便可得出搀杂的纤维雏形。该方法的缺点为搀杂数量的不确定和物质的成团，这会损害最终所得成品的性能。另外，活性纤维能用气悬体法生产，其中含有铒的气悬体是由超声法生产的。将用超声法分开生产的气悬体引入到一个热反应器内，使它们起化学反应便可生产出多组分玻璃。这种方法的缺点是搀杂时的复杂和困难以及所生产颗粒的尺寸偏大，其数量级约为一个微米。
本发明的目的是要提供一种能避免上述缺点的方法和装置。
按照本发明的方法的特征为，将第一组分以气体或蒸气的形式引入到火焰中，将第二组分以液体的形式引入到火焰中，并使它被一基本上在火焰附近的气体雾化，其中第一组分和第二组分都用与输送燃料气体相同的装置被供应到火焰中。
另外，按照本发明的装置的特征为，该装置有一气体细管，以气体或蒸气的形态将第一组分引入到火焰中，有一液体细管，以液体的形态将第二组分引入到火焰中，还有一个气体细管用来将雾化气体引入到液体细管的附近，以便将基体上在火焰附近的第二组分雾化，其中第一和第二组分都用与输送燃料气体相同的装置被供应到火焰中。
本发明的主要创意为至少有两个不同的组分被引入到火焰中，并且第一组分是作为气体或蒸气被引入到火焰中，第二组分是以液体形态被引到火焰中，并且被基本上在火焰附近的一种气体雾化，而且第一和第二组分连同燃料气体都用同一装置被送到火焰中。这样液体组分和气体组分就可形成大小为纳米数量级的颗粒，而且它们的相互反应可形成均匀的多组分的玻璃颗粒。产生的颗粒能被火焰导引到各种物料的表面上，或者能用合适的装置将它们收集成为分散的颗粒例如可用来生产活性纤维。
本发明的优点为能以极其简单而便宜的方式产生含有至少两种组分的极细而均匀的颗粒，如多组分的玻璃颗粒。
下面本发明将结合附图较详细地说明，其中：
图1为一侧视图，概略地示出本发明一个火焰喷射装置的整体，
图2为一前视图，概略地示出本发明装置的喷嘴部分。
图1示出本发明的火焰喷射装置。火焰喷射枪1被用来生成火焰9，借以喷射物料。所需的气体分别沿着气体导管2、3、4和5被供应到火焰喷枪1中。沿着气体导管供应的气体有：生成火焰用的燃料气体，供喷射液体用的雾化气体，含有至少两种组分的物料如多组分玻璃中的一种呈气态或蒸气形态的组分，和可能要被生产来控制反应的气体。按照需要被供应到火焰喷枪1内的气体的数目，气体导管2-5的数目自然应该足够。要被制出的多组分玻璃的第二个组分以液体的形式沿着液体导管6被供应到火焰喷枪1内。该液体例如可用喷射泵7沿着导管6泵送。这种液体输送也可用其他方法如从压力储罐中供应液体来完成。
如图1，在火焰喷枪的右端有一喷嘴8，在那里燃料气被点燃产生火焰，液体被一雾化气体雾化，雾化基本上在火焰的附近进行，液体组分能被雾化成极细的颗粒，其大小在约一纳米的数量级。与此类似，同样小的颗粒能在气体或蒸气组分中形成。两种组分连同燃料气体都用同一装置输送到火焰中。最好燃料气体及第一和第二组分输送到火焰中都用同一装置来进行，即通过公用的喷嘴8如图1所示。这样就很容易将要被喷射的多组分玻璃颗粒导向目标。第一和第二组分的颗粒共同反应便形成多组分的玻璃颗粒。多组分的玻璃颗粒可被火焰9进一步导向各种材料的表面，或者可用合适的装置收集成分开的颗粒。
多组分玻璃的液体组分沿着液体导管6被导到火焰喷枪1内。液体从液体导管6被转移到火焰喷枪1的中心内的液体细管6a内。沿着第一气体导管2，用来雾化液体用的气体被引入到环绕液体细管6a的第一气体细管2a内。沿着第二气体导管3，第二气体被引入到环绕第一气体细管2a排列的第二气体细管3a内。另外，沿着第三气体导管4，第三气体被引入到环绕第二气体细管3a排列的第三气体细管4a内，及沿着第四气体导管5，第四气体被引入到环绕第三气体细管4a排列的第四气体细管5a内。液体细管6a和第一、第二、第三和第四气体细管2a、3a、4a和5a为排列在同一轴线周围的细管。从第一气体细管2a流到喷嘴8内的气体将沿着液体细管6a流动的液体雾化成微滴。
要被制造的多组分玻璃的液体组分可以是所需离子的合适的水溶液或酒精溶液。例如在生产活性纤维即光增强纤维时，可能使用一种含有硝酸铒、水或酒精的溶液和可溶于水或酒精的铝的一种形态。沿着第一气体导管2，例如可供应氢，它可将喷嘴8内的液体雾化。沿着第二气体导管，可供应呈气体或蒸气形态的四氯化硅或四氯化锗。沿着第三气体导管4可输入氧。在通过喷嘴8后，氢和氧起化学反应而产生火焰。在火焰内发生反应的精确过程并不清楚，但在实用上可假定，四氯化硅或四氯化锗在反应后生成极小的二氧化硅或二氧化锗的颗粒，而液体组分反应后生成氧化铒和氧化铝。生成的颗粒再互相化合，或是与上述反应同时或是分开，这样来制成均匀的多组分玻璃。产生的多组分玻璃颗粒被火焰9导引到目标10的表面上，在制造活性纤维时这个目标物为一心轴，从而多组分玻璃颗粒便可在心轴表面上制成一个多孔的玻璃表面。如果需要，在心轴表面上能够积聚几个不同的玻璃层，其材料的组成可以简单的方式加以改变。在积聚后，心轴可被抽去，而产生的雏形可被烧结，其方式如同光纤的制造过程那样。
第四气体导管5和相关的第四气体细管5a并非必需，但当希望改善对反应的控制时可以使用，例如可把氩或其他合适的保护气体沿着第四气体导管5进而沿着第四气体细管5a输入。保护气体可防止外部氧在反应中的影响。
应该注意到在图1中，为了清晰起见，火焰喷枪的结构被放大得比实际情况大。为了有效地雾化，最好使喷射气体的速度尽可能地高，这样，喷嘴8的孔就应做得足够小。另外，液体细管6a和第一气体细管2a可被这样描述，所说两根细管在结构上好像两根套合在一起的针。
图2示出喷嘴8的前视图。其中在液体细管6a端头的孔处在喷嘴8的中心。第一气体细管2a的孔环绕着这个孔。如图所示，将沿着第二气体细管3a流动的气体表示为经孔眼11通过喷嘴8。与此相似，将沿着第三气体细管4a流动的气体表示为经孔眼12通过喷嘴8，将沿着第四气体细管5a流动的气体表示为经孔眼13通过喷嘴8。喷嘴8的孔和这些孔眼的大小和几何形状可按需要而变，但主要的是在喷嘴8内的液体和雾化气体的速度可按需要调节，使液体能够形成足够小的微滴，致使能产生足够小的颗粒，而在另一方面，能给产生火焰9的气体提供足够的速度。
附图和相关的说明阐明本发明的创意。在权利要求的范围内，本发明的细节是可变化的。因此，液体细管和气体细管的位置和次序可按所需的方式变化。另外，在上述方式下，燃料气能由两种或多种气体构成，并分别沿着分开的气体细管供应到喷嘴8上，或者所用燃料气体可为一种气体或气体混合物如氧气和乙炔的混合物，沿着一根气体细管供应到喷嘴8上。
