この発明は、液化燃料を気化させた原料ガスから燃料ガ
スを生成して輸送する方法に関するものであって燃料用
ガス供給設備に適用するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for producing and transporting fuel gas from a raw material gas obtained by vaporizing liquefied fuel, and is applied to fuel gas supply equipment.
（従来技術）
液化ガスから燃料用ガスを製造する場合の一般的なフロ
ーは第１図に示すようであって、貯蔵タンク（１）内の
液化燃料をポンプ（２）によって気化器（３）に導入し
気化した原料ガスをベンチュリミキサー（４）に０．５
〜５ｋｇ／ ｃｒＡの圧力で噴出させて空気と混合して
いる。(Prior Art) The general flow for producing fuel gas from liquefied gas is as shown in Figure 1, in which liquefied fuel in a storage tank (1) is pumped into a vaporizer (3) by a pump (2). The vaporized raw material gas is transferred to the Venturi mixer (4) at a rate of 0.5
It is ejected at a pressure of ~5 kg/crA and mixed with air.
この方法によると例えば熱量３２．０００ｋｃａ９／
ｒｒｌの原料ガスから熱量７，０００７／ ｒｒｌの燃
料ガスを得る場合の空気量は原料ガス１に対して約３の
割合にする必要がある。According to this method, for example, the amount of heat is 32,000 kca9/
When obtaining a fuel gas having a calorific value of 7,0007/rrl from a raw material gas of rrl, the amount of air needs to be at a ratio of about 3 to 1 part of the raw material gas.
このためミキサーの二次側圧力は０．１８ｋｇ／ ｃｕ
ｔが限界であって、通常は０．１５ｋｇ／ ｃｕｔ位に
低下し、この圧力では高圧ガスホルダーに貯留すること
は不可能であるから低圧ホルダー（２００ｍｍ Ａｇ）
（５）に貯留せざるを得す、このため広い設置スペース
が必要になるばかりでなく末端需要家に供給するには昇
圧用ブロワ−（６）も必要になる。Therefore, the pressure on the secondary side of the mixer is 0.18 kg/cu
The limit is t, which usually drops to about 0.15 kg/cut, and it is impossible to store it in a high pressure gas holder at this pressure, so a low pressure holder (200 mm Ag) is used.
(5), which not only requires a large installation space but also requires a pressure boosting blower (6) to supply to end users.
（目的）
本発明の目的は、上記従来法による場合の混合器の導入
圧及び背圧の限界を超えて共に高圧下での運転操業を可
能にして生成ガスを高圧タンクに貯蔵し、需要家への供
給には減圧供給することによって供給コストを低減でき
る方法を提供することにある。(Objective) The object of the present invention is to enable operation under both high pressure, exceeding the limits of the introduction pressure and back pressure of the mixer in the case of the conventional method, and to store the produced gas in a high-pressure tank, so that it can be used by consumers. The object of the present invention is to provide a method that can reduce the supply cost by supplying the product under reduced pressure.

たものである。(Structure) The present invention enables high-pressure storage using a spiral fluid flow generating device (Japanese Patent Application Laid-Open No. 62-58100) proposed by the present inventor.
即ち、原料ガスを一次気体として５〜１０ｋｇ／ ｃｎ

ガスホルダに導入するようにしたものである。That is, 5 to 10 kg/cn using the raw material gas as a primary gas.
! The secondary gas, normal pressure or pressurized air, is inhaled from the suction tube connected to the back of the mixing chamber by using the negative pressure generated near the jetting part, and the primary gas is A predetermined mixing ratio (calorific value) by varying the gas pressure
At the same time, this high-pressure mixed gas is introduced into the high-pressure gas holder by utilizing the effect of reducing piping pressure loss due to the spiral flow generated in front of the mixing chamber.

備え、且つそれ自体が二次気体を吸入する吸気案内体（
１７）とから構成されている。The structure of the mixer (7) is as shown in Fig. 3, which includes a mixing pipe (12) with a flared part (11) formed on the inner surface connected to the mixed gas transport pipe (10), and an edge of the flared part (13). ) at a predetermined angle in the range of 30 to 90'' to form an annular slit (14) for ejecting primary gas, and a flange (16) forming a distribution chamber (15) around the outer periphery of the annular slit; Intake guide that itself inhales secondary gas (
17).
吸気案内口（１７ａ）は環状スリット（１４）及び輸送
管（１０）と同心配置であることが望ましい。It is desirable that the intake guide port (17a) is arranged concentrically with the annular slit (14) and the transport pipe (10).

なお、スリット巾は噴出圧力、混合比等に応じて可変す

によって５〜１０ｋｇ／ｃｏｆに調整されて一次気体供
給管（２０）がら分配室（１５）を経て環状スリット（
１４）から混合室（７ａ）内に供給される。(Function) The liquefied fuel in the storage tank (1) is introduced into the vaporizer (3) by the pump (2), where it is gasified and sent to the pressure regulator (21).
The primary gas supply pipe (20) passes through the distribution chamber (15) and then flows through the annular slit (
14) into the mixing chamber (7a).
スリットからの噴出流によって混合室（７ａ）内には負
圧を生じこの負圧に伴なって二次気体が吸入される。A negative pressure is generated in the mixing chamber (7a) by the jet flow from the slit, and secondary gas is sucked in with this negative pressure.
二次気体の吸込量は、スリットからの噴出流速即ち一次
気体の圧力に比例するからこの圧力を調節することによ
って所望の混合比が得られる。Since the amount of secondary gas sucked in is proportional to the flow velocity of the jet from the slit, that is, the pressure of the primary gas, a desired mixing ratio can be obtained by adjusting this pressure.
生成された混合ガスはフレア部（１１）に沿って流れる
噴出流によるコアンダ効果によって混合室のフレア部（
１１）に沿って進行し、この進行の過程で輸送管内に必
然的にスパイラル流を形成する。The generated mixed gas flows through the flare section (11) of the mixing chamber due to the Coanda effect caused by the jet flow flowing along the flare section (11).
11), and in the process of this movement, a spiral flow is inevitably formed within the transport pipe.
スパイラル流は中心軸流速が大きく輸送管壁との摩擦が
少ないことから当然輸送管内圧力損失は通常の整流より
も小さくなる性質がある。Since the spiral flow has a high central axial flow velocity and little friction with the transport pipe wall, the pressure loss within the transport pipe is naturally smaller than that in normal rectification.
このため輸送管路は曲管路であってもよい。For this reason, the transport pipe may be a curved pipe.
このような理由からホルダー（８）へは約１ ｋｇ／−
の高圧力で送給が可能であるから高圧ホルダーを使用で
きるのである。For this reason, approximately 1 kg/- is attached to the holder (8).
Since it is possible to feed at a high pressure, a high pressure holder can be used.
従って、需要家にはブロワ−によって昇圧しなくても圧
力減圧調節だけで供給できる。Therefore, the product can be supplied to customers by simply adjusting the pressure to reduce the pressure without increasing the pressure using a blower.

アンダ効果をより一層高め混合ガスの吐出背圧を増大さ
せることが可能である。In the present invention, the suction air, which is a secondary gas, is passed through a blower (2
2) etc., and by supplying it via the flow rate or pressure regulating device (23), it is possible to further enhance the Coanda effect in the mixing chamber and increase the discharge back pressure of the mixed gas.
更にこの場合には加圧系に適当なフィルタを介在させる
ことによって混合器及び輸送系に導入される塵埃を遮断
できる。Furthermore, in this case, by interposing a suitable filter in the pressurization system, it is possible to prevent dust from entering the mixer and the transport system.
（効果）
このように本発明によれば一次気体である燃料ガス圧力
を規制値の最高圧力１０ｋｇ／ ７で混合器に供給でき

器自体がベンチュリミキサーに較べて小型で構造が単純
であるがら容易に製作できる利点がある。(Effects) As described above, according to the present invention, fuel gas pressure, which is the primary gas, can be supplied to the mixer at the maximum pressure of 10 kg/7 of the regulation value, and in addition to easily obtaining a high-pressure mixed gas, the mixer itself can Compared to the Venturi mixer, it has the advantage of being smaller and simpler in structure and easier to manufacture.
またスパイラル流によって輸送するので輸送管壁に原料
中の重質分が付着し難い効果もある。Furthermore, since the material is transported by a spiral flow, there is an effect that heavy components in the raw material are less likely to adhere to the walls of the transport pipe.
