Description
【０００１】[0001]
本考案は、加熱配管を使用して煙道排ガスなどのサンプルガスを分析装置へ供 給する加熱配管機構に関するものである。 The present invention relates to a heating pipe mechanism for supplying a sample gas such as a flue gas to an analyzer using the heating pipe.
【０００２】[0002]
ＳＯ2 ，ＮＯx 計などの分析装置を用いて煙道排ガスなどの高温のサンプルガ スを分析するに際し、ドレンに溶解損失を生じる成分を測定する場合には、加熱 配管を使用している。When analyzing a high temperature sample gas such as flue gas using an analyzer such as a SO 2 or NO x analyzer, a heating pipe is used to measure the component that causes dissolution loss in the drain.
【０００３】[0003]
この場合、加熱配管と分析装置間の外気雰囲気中に配設されている配管むき出 し部でサンプルガスを外気温度まで冷却し、サンプルガス中の水分をドレン化さ せることが必要になるが、前記むき出し部の長さが短く施工されることが多く、 温度の高い夏期においては冷却不充分により、サンプルガス中の残りの水分が分 析装置内でドレン化することになる。したがって、ＳＯ2 ，ＮＯ2 の溶解やドレ ンの再蒸発などにより、指示異常などが起こる。In this case, it is necessary to cool the sample gas to the outside air temperature in the exposed part of the pipe arranged in the outside air atmosphere between the heating pipe and the analyzer to drain the water in the sample gas. In many cases, the exposed part is constructed with a short length, and in summer when the temperature is high, insufficient cooling causes residual water in the sample gas to be drained in the analyzer. Therefore, due to the dissolution of SO 2 and NO 2 and the re-evaporation of the drain, an abnormal indication occurs.
【０００４】 さらに、温度の低い冬期において、例えば、寒冷地などではサンプルガスを保 温するのが難しく前記管内部のドレンが凍結する場合もある。Furthermore, in winter when the temperature is low, for example, in a cold region, it is difficult to keep the temperature of the sample gas, and the drain inside the tube may freeze.
【０００５】 本考案は、上述の事柄に留意してなされたもので、その目的とするところは、 サンプルガス中の水分を確実にドレン化でき、かつ凍結を防止できる加熱配管機 構を得ることである。The present invention has been made in consideration of the above matters, and an object thereof is to obtain a heating pipe mechanism capable of reliably draining water in a sample gas and preventing freezing.
