Abstract
本发明涉及一种用气体稀释磷化氢的喷嘴,包括一个管状的导气装置、一个环状的安装的切口和/或在至少一边上的安装的小管,作为PH3引导(引导器),因此切口开口/或小管的开口的厚度的最大值是管状导气装置(引导器)的直径的1/25和或在空气引导部件的表面和在PH3入口的区域的管状导气装置的内侧之间的距离的1/25。空气引导装置的形状为弹头形。
Description
所属的技术领域
本发明涉及一种稀释磷化氢(化学分子式为PH3)的喷嘴。
背景技术
众所周知，几十年来，PH3被用做害虫防治和存储保护中的预防的介质，尤其是关于食品领域(用于人类和动物)。
已知，PH3与空气一起形成易燃性的气体混合物，因此燃烧的临界点是PH3的浓度为1.8％。如果超过此临界点，PH3往往自燃。
因此，产生了许多的处理方法和设备以便在没有危险的情况下用空气稀释PH3。
根据最新的现有技术德国专利(专利申请已公开)No 198 39 385，其公开了一种用空气直接稀释PH3的有效的处理方法，即在水存在的情况下进行空气和PH3的混合。以及现有技术德国专利NO 691 29 456和公开的国际专利申请WO93/25075A1。
关于技术背景，可以说在空气和PH3的可燃性混合气体燃烧的情况下，反应区会以超声波的速度传播。
当PH3流在空气流中被引导时，将立即发生自燃，因此在PH3的出口处将发生小爆炸；由于爆炸产生的膨胀和接下来的收缩过程，小爆炸会立即产生所谓的共振过程。
此现象将伴随着鸣笛噪音。这些爆炸将产生象磷酸和多磷酸的混合物的黄-红的液体。
通过采用小孔在空气流中添加PH3也可以检测到相同的现象，因此孔洞总是被污染的黄酸所弄脏，因此孔洞的直径在1-2mm时会被堵上。
德国专利198 39 385可以避免上述的不良现象。因为水产生了爆炸的共振。
实用新型的内容
本发明提供了一种喷嘴形式的装置，该装置是一种容易运输的便携装置，可以在需要工作的地方快速地使用。
因此本发明描述了一种通用的可快速使用的装置。
例如，根据本发明的喷嘴可以在1小时内使90000升的空气与PH3混合，达到空气中的PH3浓度为10000ppm。
根据本实用新型在喷嘴中燃烧的产生可以通过如下事实而防止，即临界条件只在非常薄的层中出现。PH3层将立即被强空气流推动，而与空气混合。
通过此方法，可能产生包含上限为10000ppm PH3的混合物，而没有在混合区自燃的危险。这可以通过以下事实来控制，即在混合区不会产生黄色的磷酸。
本实用新型包括一个管状的导气装置，一个环状的安装的切口(环切口)和/或在至少一侧安装的小管，作为PH3引导(引导器)。因此切口的开口/或小管的开口的厚度的最大值是管状导气装置(引导器)的直径的1/25和或在空气引导部件的表面和在PH3入口的区域的管状导气装置的内侧之间的距离的1/25。
本实用新型是根据令人吃惊的基础知识，即沿着管状空气引导装置的内壁产生的PH3流将影响到空气和PH3的优化混合，没有到燃烧临界点的燃烧的危险。
在将一个红热的铁杆安置在喷嘴的混合处的前面，PH3的浓度最高为5000ppm，不会发生持续的燃烧。只有当发生燃烧时，才能听到鸣笛的噪音。在实践中由于气体的冲击，不会使用PH3浓度高于2000ppm的混合物。
附图说明
本发明的特征在附图1-3中介绍，附图所示为本发明的最佳实施例。附图所示为本发明的设备的剖视图。
具体实施例
图1所示的实施例包括一个管，其两端开口，标号为1。此管有一个环状的环切口2，在箭头4方向有一个适配器3穿过。PH3按以下顺序流过，在入口处5沿着管1的壁流动。在同时，空气以箭头6a的方向在管1的开口6中以非常高的速度流过，因此，已经具有层流特性的PH3流将产生一个更薄的层。空气PH3的混合物的出口的标号为7，混合物的流动方向为标号7a。
根据最佳实施例，为了增加在层流PH3上的非常快的流动气体的压力，在管1中安置了一个弹头状的部件8，其头部为锐角，显示的方向指向空气入口6，因此，弹头状的部件8的最厚的区域被安置在环切口的区域；8就是所谓的空气导流部件。
被导流通过管的空气的压力超过350-440mm水柱，速度为250-370km/h。
PH3的出口切口2的直径通常不超过0.2mm。对喷嘴的环切口的直径0.6mm，0.3mm和0.1mm作了试验，因此后者的值是所发现的最优值。由于弹头状的部件8的存在，结果导致在PH3层上的空气层9的厚度在最优的情况下不超过5mm的值。
根据图2的实施例，与图1相比，没有弹头状的部件。
根据本发明，喷嘴可以容易地建立在一些部件之外，这些部件可以迅速地安装在一起，因此这些部件被O形环固定。喷嘴其最好是用不锈钢制成，可以非常方便地与不同的部件拆卸，并且在必要的情况下可以方便地控制和方便地清洗。
根据图3所示的进一步的实施例，PH3引导器的功能是通过不同的小管来实现，这意味着环切口被小管部分地或全部地代替，它们的出口平行于管1的内壁安置。
图3所示为根据本发明的用小管部件穿过喷嘴。
管，其两端开口，标号为1，小管的标号为2，弹头状的空气导流部件的标号为8，环状适配器部件的标号为10。
