本発明は、気体が通過する通過筒に関する。 The present invention relates to a passage cylinder through which gas passes.
各種煙突、各種気体や蒸気の通過筒、または水などの液体の排出のための通路などの通過筒は、これまで、円筒状のもので内部は平面若しくは滑面のものである。 Until now, passage cylinders such as various chimneys, passage cylinders for various gases and vapors, or passages for discharging liquid such as water are cylindrical ones and the inside is flat or smooth.
各種煙突、各種気体や蒸気の通過筒、または水などの液体の排出のための通路については、その流れる気体等が速く移動させることが望まれています。 With regard to various chimneys, various gas and vapor passage cylinders, and passages for the discharge of liquids such as water, it is desirable that the flowing gas, etc., be rapidly moved.
そのため従来、煙突の場合には、ブロワーなどの動力源を途中に組み入れて、外部の空気を強制的に入れて、ばい煙等の排出スピードを速くするというものがあります。ただし、外部電源が必要となり、エネルギー負担を要します。 Therefore, conventionally, in the case of a chimney, a power source such as a blower is incorporated along the way, and the external air is forcedly introduced to accelerate the discharge speed of soot and the like. However, an external power supply is required and an energy burden is required.
本考案の考案者は、蒸気の通過筒の内部の表面に凹部を形成してらせん状のガイドを設けることで、このらせん状のガイドを付けない場合と比して蒸気の排出スピードが速くなることに気が付いた。 The inventor of the present invention can provide a spiral guide by forming a recess on the inner surface of the steam passage cylinder, so that the speed of discharging the steam can be increased compared to the case where the spiral guide is not provided. I noticed that.
そこで、本考案者は、試行錯誤を経て、気体の通過筒であって、気体の供給口に接続することができ、通過筒の内部は円柱状の空洞となっており、且つ、通過筒の気体の供給口側から他の出口に向けて、前記通過筒の内部の表面に凹部を形成してらせん状のガイドを設けることを特徴とする気体の通過筒を考案した。 Therefore, the inventor of the present invention, through trial and error, is a gas passage cylinder that can be connected to a gas supply port, and the inside of the passage cylinder is a cylindrical hollow, and the passage cylinder is The gas passage cylinder is characterized in that a recess is formed on the inner surface of the passage cylinder from the gas supply port side to the other outlet to provide a spiral guide.

前記気体が蒸気であることを特徴とする通過筒としても良い。ここで、蒸気は飽和蒸気でも、過熱蒸気でも良く、この場合には高温の蒸気でも耐えられる素材とする。 The passage cylinder may be characterized in that the gas is a vapor. Here, the steam may be saturated steam or superheated steam, and in this case, it is a material that can withstand high temperature steam.
通過筒の断面は円形でも、楕円形でも良い。また、通過筒の直径は適宜選択できるものとする。通過筒の内部の表面に凹部を形成してらせん状のガイドでの、凹部の断面積についても適宜選択できるものとして、らせんの勾配、すなわち任意の通過筒に対して、何回転で入口から出口に向かう設計であるかについても適宜選択できるものとする。 The cross section of the passage tube may be circular or elliptical. In addition, the diameter of the passage cylinder can be appropriately selected. A recess is formed on the inner surface of the passage cylinder so that the cross-sectional area of the recess in the spiral guide can be appropriately selected as well: the inclination of the helix, ie how many rotations from the inlet to the outlet It is also possible to select as appropriate whether the design is directed to
通過筒の内部は円柱状の空洞の直径と、前記凹部を形成するらせん状のガイドの径の長さが０．５以上となることを特徴としても良い。 The inside of the passage cylinder may be characterized in that the diameter of the cylindrical cavity and the length of the diameter of the spiral guide forming the recess are 0.5 or more.
このような形状を有する通過筒を用いて、煙突を構築することにより、外部動力を無くす、または、低減させて素早くばい煙を排出させることができるので、環境性能の良い煙突ができ、また、省エネ性能の高い煙突を提供することができる。 By constructing a chimney by using a passage cylinder having such a shape, it is possible to eliminate or reduce external power quickly and to discharge soot smoke quickly, resulting in a chimney having good environmental performance, and energy saving. A high performance chimney can be provided.

以下、添付図面及び実施例を組み合わせて本発明を更に説明する。 The invention will now be further described by combining the attached drawings and examples.
本考案の通過筒について説明する。 The passage tube of the present invention will be described.
本考案は、気体の通過筒であって、気体の供給口に接続することができ、通過筒の内部は円柱状の空洞となっており、且つ、通過筒の気体の供給口側から他の出口に向けて、前記通過筒の内部の表面に凹部を形成してらせん状のガイドを設けることを特徴とする気体の通過筒である。 The present invention is a gas passage cylinder, which can be connected to a gas supply port, and the inside of the passage cylinder is a cylindrical cavity, and the other from the gas supply port side of the passage cylinder It is a gas passage cylinder characterized in that a concave portion is formed on an inner surface of the passage cylinder toward the outlet to provide a spiral guide.
本通過筒の基本形状は、円柱状の筒状のもので、内部に表面に凹部を形成してらせん状のガイドを設けている（図１）。図は、本考案の通過筒の外観を表しており、外部から見ると内部が凹んだ分、外部に凸部が表れていることが分かる。 The basic shape of the passage cylinder is a cylindrical cylinder, and a concave portion is formed on the surface inside to provide a spiral guide (FIG. 1). The drawing shows the appearance of the passage cylinder of the present invention, and it can be seen that when viewed from the outside, a convex portion appears on the outside because the inside is recessed.
また、内部の凹部の断面は略半円状で、全体としてらせん状のガイドを構成している。 In addition, the cross section of the recess inside is substantially semicircular, and constitutes a spiral guide as a whole.
図２は、本考案の通過筒を用いた蒸気排出の様子を観察した実験を示す説明図である。本考案の通過筒による蒸気の排出スピードの速度変化を観察する目的である。 FIG. 2 is an explanatory view showing an experiment in which the state of steam discharge using the passage cylinder of the present invention was observed. It is an object to observe the speed change of the discharge speed of steam by the passage cylinder of the present invention.
まず、蒸気を発生させるために開放系の容器に水を入れて、その下部にアルコールランプを置き、水を加熱して飽和蒸気を発生させる。図２では、水を斜線部で示している。これを漏斗状のガイドを介して、本考案の通過筒に蒸気を入れる。発生した蒸気は、すべてこの通過筒に入れるものとする。 First, water is put into an open system container in order to generate steam, an alcohol lamp is placed under it, and the water is heated to generate saturated steam. In FIG. 2, the water is indicated by hatched portions. The steam is introduced into the passage tube of the present invention through a funnel-like guide. All generated steam shall be put into this passage cylinder.
実験では、比較対象として、らせん状のガイドの無い通過筒、すなわち、内面が滑面（凸凹の無いもの）である通常の円柱状の通過筒を用意した。いずれの通過筒も、その直径は同一のものとした。本実験では、通過筒の内部は円柱状の空洞の直径は５ｍｍとして、螺旋部分の径は７ｍｍとした。 In the experiment, as a comparison object, a passage cylinder without a helical guide, that is, a normal cylindrical passage cylinder whose inner surface is a smooth surface (without unevenness) was prepared. The diameter of each passage cylinder was the same. In this experiment, the diameter of the cylindrical cavity inside the passage cylinder was 5 mm, and the diameter of the spiral portion was 7 mm.
アルコールランプ、水の量、水を入れた容器、漏斗状のガイドといった通過筒は、すべて同一のものを用意して、通過筒の内部形状の違いのみで、蒸気の排出スピードに違いがでるかを観察した。 Make sure that there are different items in the passage tube such as alcohol lamp, water volume, water container, funnel-shaped guide, etc., and only the difference in the inner shape of the passage tube, the difference in the steam discharge speed Observed.
蒸気の排出スピードは、デジタル風速計を用いて測定した。本実施例では、「Anemo meter」製の型番「NO.20180325761」を使用した。測定は、十分に蒸気が出て安定した時点で実施した。 The steam discharge speed was measured using a digital anemometer. In this example, the model number "NO. 20180325761" manufactured by "Anemo meter" was used. The measurement was carried out when sufficient steam was released and stabilized.
通常の円柱状（らせん状のガイドの無い通過筒、内面に凸凹の無いもの）では、0.85 m／sであった。本考案のらせん状のガイドの無い通過筒では、1.46m／sであった。すなわち、本考案により蒸気の排出スピードは、約１．７倍となった。 It was 0.85 m / s in the case of a regular cylindrical shape (passage tube without a helical guide, without unevenness on the inner surface). It was 1.46 m / s in the passage cylinder without a spiral guide of the present invention. That is, the discharge speed of steam has been increased by about 1.7 times by the present invention.
