Abstract
从含尘气中抽取气样的取样器有带冷却套(11)的管道(2),它通到带过滤器(5)的过滤室(4)中。管道进口(1)是收缩形的以减低气体流速,并因此降低携带粉尘量。
Description
本发明涉及一种从热尘气流中抽检气体的取样器,例如从焙烧炉的气流抽取气样。
这种取样器为承受热气流,必须被冷却,所抽检的样气也须过滤来除去吸进样气中的灰尘。由于几乎不可能有一种能长时间承受热气流的过滤器,所以过滤器是这样置放,即样气在冷却之后才接触过滤器。
再有,还必须降低样气中的含尘量来防止过滤器很快被堵塞。
根据DE-A-3327180号专利,具有冷却介质可以通过的冷却罩,以及取样器一端有进气口的取样器可达到上述要求。当把取样器装进气流中时,取样器可以抽取样气,进气口开在取样器的背风面。
涉及到我们英国专利第8517549中描述的快速气体监视仪,由于是用泵把样气从取样器中吸进分析站里,所以取样器中冷却的气体以很快的速度通过取样器和相连的管道。而在取样器的进气口处,未能冷却的样气体积大,所以取样器进气口处气体速度极快,使得带走粉尘量增大。
因此,本发明的目的是提供一种进气口处气体速度低的取样器,根据本发明的取样器可以达到这一目的,它有带冷却装置的管路,从进气口处通到带过滤器的过滤室,其特征是,进气口在进入管路方向上是收缩形的。
这种收缩形,最好是截头圆锥形的进气口,可以降低气体中的
夹带粉尘量,其中,进气口前部的面积越大,气体速度就越低,因此带走粉尘量也就越小。
在收缩形进气口中,气体加速到必要的高速度,以防止在通向过滤室管道中的带走粉尘沉降在管道的出口端。
管道与过滤室间的转换导管可以是扩展形的,最好是截头圆锥形的,当与取样气流反向间歇地通入压缩空气脉冲来清理时,可以提高过滤器和取样管的除尘效率。
为把取样器的反应时间缩到最短,过滤室的形状可以与所选的市场上的标准过滤器外形大体相一致,在过滤器与过滤室间只留很小的间隙。再有,如果过滤器在出口处有一个空腔,那么可以用一个构件大致填满这个空腔,这个构件是取样器壳体上的一部分。
这个构件有一个通道,该通道至少在面对过滤器内端的一头是喷嘴状。这个通道用来把压缩空气通入取样器以清理过滤器。并且这个通道还可以用作取样器的出气口。然而,也可选择另一个通到过滤器出口处的管道作为出气口。
取样器的新结构可以仅使用金属构件,因此克服陶瓷与金属共用时不同热膨胀率的缺陷。
下面结合附图详细说明本发明,附图示出了根据本发明的取样器的一个实施例的轴向剖视图。
其中,取样器基本上是一个整体,尽管实际上它可以是由若干构件组成的。
取样器有收缩形锥形进气口1,从口1通出管道2经扩展的锥形转换管3到达过滤室4,在过滤室4中装有烧结金属结构的过滤器5。
构成取样器外壳一部分的一个构件6填满了过滤器5的空腔7的
大部分。构件6有一个轴向出口通道8从过滤器的空腔中通出。通道8既可以用作出气道,又可以为清洗目的把加压空气通入过滤器5,因此,在通向空腔7的开口处可以有喷嘴9。
因为取样器的目的是从气流中抽取热气,所以至少伸进热气流中的那部分应能被冷却。再者,被吸取的样气应在接触到过滤器之前被冷却。冷却是通过经管子10向围绕管道2的圆柱冷却套加注冷却液来完成的。冷却液从冷却套11通过开口12,进入圆柱冷却管道13,冷却管道13靠近取样器发热部分的外圆柱表面,管道13中的冷却液再通过一个管子14排出取样器。
尽管应冷却样气来保护过滤器5,但是却不能冷却到它的露点以下,而在管道2中的冷凝有损于取样器的功能。为避免管道2中的冷凝,管内冷却液可以用已知的方法在加注到冷却套11内之前,将其予热到高于进入管道2内样气的露点的温度。
