本考案は2種類の気体を混合するための装置に

装置では多数の注入穴4を形成しなくてはなら
ず、この場合にも高価になるという欠点がある。 Conventionally, as shown in FIG. 1, a gas mixing device includes a first gas flow pipe 1 and a second gas ejection pipe 2 having a jet nozzle 2A disposed concentrically within the flow pipe 1.
There is also a device consisting of a stirring blade 3 disposed concentrically with the flow pipe 1 downstream of the jet pipe 2, but in this conventional device, the shape of the stirring blade 3 is complicated and expensive. There is a drawback. Furthermore, as shown in FIG. 2, there is a device in which a header 5 having an injection hole 4 is arranged concentrically with the flow tube 1 inside the flow tube 1, but in this conventional device, a large number of injection holes 4 are not formed. However, this case also has the disadvantage of being expensive.

を完全に混合することができるものである。 Therefore, the present invention provides a gas mixing device that eliminates such drawbacks, and its feature is that the ejection port of the second gas ejection pipe is placed in the first gas flow pipe in a concentric manner with the flow pipe. A funnel-shaped cone, which is disposed downstream of the ejection pipe in the flow pipe, has an opening at one end that is smaller in diameter than the ejection port, and whose side wall extends outward from the opening at one end toward the opening at the other end. This is due to the fact that it is arranged concentrically with the flow pipe,
According to this configuration, the structure is extremely simple and inexpensive, and two types of gases can be completely mixed using the Karman vortex.
以下、本考案の一実施例を第3図および第4図
に基づいて説明する。すなわち第1気体の流通管

斗状のコーン6を流通管1と同芯状に配設したこ
とにある。 An embodiment of the present invention will be described below with reference to FIGS. 3 and 4. That is, the ejection port 2A of the second gas ejection pipe 2 is disposed in the first gas flow pipe 1 so as to be concentric with the flow pipe 1, and one end opening 6A is provided downstream of the ejection pipe 2 in the flow pipe 1. A funnel-shaped cone 6 is arranged concentrically with the flow pipe 1, and has a smaller diameter than the spout 2A, and the side wall extends outward from the opening 6A at one end toward the opening 6B at the other end. It is in.
上記構成において、噴出管2の噴出口2Aから
噴出された第2気体のうち、その一部は一端開口

進む。したがつてコーン6内は減圧状態となる。
また第2気体の残りはコーン6の外周面に沿つて

合され、コーン6の他端開口部6Bと流通管1の
内周面との間のリング状の狭い空間を通過したと
ころでカルマン渦が発生し、第1、第2の両気体
は完全に混合されるものである。 In the above configuration, a part of the second gas ejected from the ejection port 2A of the ejection pipe 2 linearly enters the cone 6 from the one end opening 6A and continues as it is. Therefore, the inside of the cone 6 is in a reduced pressure state.
In addition, the remainder of the second gas spreads outward along the outer circumferential surface of the cone 6, and during this time, it is mixed with the first gas, and between the other end opening 6B of the cone 6 and the inner circumferential surface of the flow pipe 1. A Karman vortex is generated when the gas passes through the narrow ring-shaped space, and both the first and second gases are completely mixed.
第3図のA−A断面における濃度分布は第4図

のようになる。 The concentration distribution on the A-A cross section in Figure 3 is as shown in Figure 4a, and when the concentration distribution A outside the cone 6 and the concentration distribution B inside the cone 6 are combined, Figure 4b
become that way.
以上述べたごとく本考案の気体混合装置によれ
