Zusammenfassung: | PROBLEM TO BE SOLVED: To provide a flow rate measuring method which allows measurement of a flow rate in each air hole in a narrow part where a space enough for disposing a normal sensor or flow rate measurement device cannot be secured, and is suitable for analyzing the drift of a gas flowing through a gas processor, and also to link the analysis of the drift of a gas flowing through the gas processor to designing of an optimal adsorption tower.SOLUTION: In a method for measuring, in a gas processor having many air holes, the flow rate of a gas passing each of the air holes, a test gas having reactivity is continuously flowed in the gas processor to allow the test gas passing each air hole to react with a detection agent closely provided in each air hole or with a detection adsorption material charged into the gas processor, and by measuring the amount of a reaction product produced between the detection agent and the test gas, the amount of change in weight of the detection agent or the amount of change in color, the flow rate of the gas passing each air hole is measured. In addition, the drift is analyzed from the flow rate of the gas passing each air hole.SELECTED DRAWING: Figure 1
【課題】通常のセンサーや流量測定装置を配置するには充分なスペースを確保できない狭隘部で通気孔ごとの流出量を計測することが可能で、気体処理装置を流通する気体の偏流を解析するのに適した流量計測方法を提供する。また、気体処理装置内を流通する気体の偏流を解析することで、最適な吸着塔の設計に結び付けることを課題とする。【解決手段】多数の通気孔を有する気体処理装置において、各通気孔を通過する気体流量を計測する方法であって、反応性を有する試験用気体を連続的に前記気体処理装置内に流し込み、各通気孔を通過する該試験用気体を、各通気孔に密着配置させた検出用薬剤あるいは気体処理装置に充填した検出用吸着材と反応させ、該検出用薬剤と前記試験用気体との反応生成物量、該検出用薬剤の重量変化量あるいは色の変化量を測定することで、各通気孔を通過する気体流量を計測する。また、各通気孔を通過する気体流量から偏流を解析する。【選択図】図1 |
