Description

从存储容器计量取出细粒至粗粒固体或固体混合物的方法和装置
技术领域
本发明涉及一种利用在计量容器的排放区域或计量腔中形成流化床层的装置从存储容器计量取出细粒至粗粒固体或固体混合物的方法,本发明还涉及一种实施该方法的相应的装置。
背景技术
为了例如能将细粒的燃料从存储容器中供给到烯烧器,众所周知,在存储容器和/或相应的计量容器的下部区域中进行流态化,随后例如借助气体从该区域进行到相应管路中的输送。作为对于这种工作方法的示例,EP531758B1、EP626196B1或DE2831208C、DE3910073A以及DE19715973A中有所提及。DE68902594T或DE4108048C描述了给气体供给元件、例如吹杆或定位在漏斗边缘上的管路配设吹出孔,以仅提到几个示例。
为了不必使容器的整个容积流态化,这会导致能量需求很大并且相应需要大量气体,还已知,仅在这种容器的下部区域内设置流态化,正如在上述DE2831208C中所描述的那样。
对于很难流态化的固体而言,众所周知,流态化通过装入件、如搅拌器等得到支持,以便尤其是实现尽可能均匀的流态化。由于高达8Mpa的比较高的压力,对密封装置、尤其是轴套管的密封装置提出高的要求。在此,固体中的高压和活动的部分导致比较高的故障易发性,该故障易发性相应地损害整个设备的可用性。
发明内容
为此,本发明的目的在于,在这种接收或计量容量的下部区域中创造尽可能优化的流态化,在比避免附加的系统、机械元件或昂贵的装入件。
通过开始所述类型的、利用在存储容器的排放区域或计量腔中形成流化床层的装置从存储容器中计量取出细粒至粗粒的固体或固体混合物的方法,按照本发明的目的这样得到解决,即,在计量腔底部的区域内引入一种气体以形成使固体松散的流化床层,并且经由涡流式喷嘴附加地引入一种气体以使流化床层旋转,固体沿重力方向向下从计量腔中被取出。通过这两种用于不同目的的气流可在很均匀地形成流化床层的情况下实现优化的流态化,由此可以均匀地取出例如燃料。
本发明可特别有利地用于从压力气化方法用的处于压力下的接受器支架中计量细粒至灰尘状的燃料,在压力气化方法中利用含氧的气化剂在高于炉渣熔点的温度时在提高的压力下将细分的燃料、如灰尘状的(<0.5mm)燃料、如煤、石油焦炭、生物废料或燃料或液态燃料如油、焦油、精炼残渣以及其它可能在气化器中被雾化的液态残渣在颗粒载荷较小(<50kg/m3;无流化床层)时的悬浮物中转化。
在此可规定:产生涡流的气流相对于计量容器壁切向地或成角度地和/或相对于水平面成角度地引入。
在此适宜的是,正切角(Tangentialwinkel)设定在0至80°之间,并且与水平面所成的角度设定在0至45°之间,正如本发明同样规定的那样。
此外有利的是,经由整个气体供给装置实现的速度关于计量容器中的流态化区域的横截面设定为在固体的最小流态化速度的0.5倍至10倍之间、优选在1倍至5倍之间。上述措施导致在待输送材料内部在气动路径上的优化的搅拌效应,从而例如可通过中央排出孔取出相应均匀的气体/固体流。
为了解决所述目的,本发明还规定了一种装置,即,用于从计量容器计量输出细粒至粗粒的固体或固体混合物的装置,计量容器具有至少一个沿重力方向位于下方的计量腔,计量腔在腔底部具有适合于形成流化床层的气体供给孔,所述装置的特征在于,除了用于流态化的气体供给装置外,设置有附加的给计量腔进气的涡流式喷嘴和沿重力方向向下指向的排出孔。如上所述,可借助涡流式喷嘴在流化床层内实现搅拌效应以及与之相关联的优点。
例如在本发明的实施方案中这样规定,即各涡流式喷嘴穿过地设置在计量腔的圆筒状壁和/或流化腔底部中。
适宜地,各涡流式喷嘴相对于腔壁具有切向的气体流动出口和/或相对于水平面具有成角度定位的流出方向,其中相应的角度可在0至45°之间、特别是在0至80°之间的范围内。
此外,本发明也规定:计量容器在容器底部区域内配备有至少两个计量腔。
计量腔底部自身可同样构造为漏斗形的,相对于水平面的定位角为0至60°、尤其是10至20°。
附图说明
本发明的其它特征、细节以及优点基于下列描述并参考附图得出。附图中:
图1示出按照本发明的装置的简化的剖面图;以及
图2示出计量腔包括在其内形成的流化床层的流动箭头的俯视图。
具体实施方式
总体上以1表示的存储容器具有固体散料2。存储容器1在下端部配备有过渡漏斗3。在此,在图1中用DFB表示固定床的直径,用DWS表示流化床的直径,用DA表示出口的内径。
过渡漏斗3通到基本上圆筒状的计量腔4中,其中可在计量腔4内产生流化床层。这里流态化的固体用5表示,6表示来自用7表示的涡流式喷嘴的气流相对于水平面的流出角。气体例如可采用氮气、空气、二氧化碳、再循环的烟气或合成气体或者这些气体的混合物。
此外,计量腔4具有略微漏斗形的底部,该底部构造成气体分配底部8,相应的通向气体分配底部的气体供给装置用10表示,通向涡流式喷嘴的气体供给装置用11表示。
流态化的燃料可经由中央排出孔12取出,并且例如供给到燃烧器,这在附图中未详细示出。
在图2中,用13表示相对于切向方向的气体流出角,来自涡流式喷嘴的气流占据该气体流出角,以便使计量腔4的流态化的内容物以一定方式循环,正如通过图2中的小箭头所示。图2也通过虚线示出涡流式喷嘴圆。
为了在供给固体(以15表示)时尽可能使装料脉冲最小化,可在计量容器1内部设置用16表示的装置、例如碰撞板或类似物。
涡流式喷嘴7不仅可穿过气体分配底部8,它们也可设置在计量腔4的垂直壁内,这用18表示,附图标记19表示相应的气体供给装置。气体分配底部8的定位角用α或9表示。气体分配底部可由多孔材料构成,具有钻孔或喷嘴或者这些结构的组合。
当然,本发明的所描述的实施例还可在多方面改变,而不脱离基本构思,尤其是可设置控制装置以有节拍地供给流态化气体和/或涡流气体,各气体供给装置可被同步地或相继依次地控制等等。
