Description
本発明は、プロパンガスなどの炭化水素ガス（以下ＬＰガスと称す）に、水素ガスと酸素ガス、または水素ガスのみを所定の混合比で均一に混合するための装置に関する。
The present invention relates to an apparatus for uniformly mixing hydrogen gas and oxygen gas or only hydrogen gas into a hydrocarbon gas such as propane gas (hereinafter referred to as LP gas) at a predetermined mixing ratio.
現在燃料として利用されている化石燃料の中で、石油は価格は安いが炭素含有量が多めであるためＣＯ２排出の面で問題があり、より炭素含有量の少ないＬＰガスはＣＯ２の排出量が少ないが価格は高い傾向にあった。
最近の状況を見るに従来より価格差が無くなり、むしろ安定供給に不安がありこの点を解決する為にＬＰガスに水素・酸素ガス、または水素ガス単体を混合することによって燃焼効率を改善し、二酸化炭素など温室効果ガスの排出量抑制及び燃料費削減を目指し、食品業界、農業・工業用、建設業、クリーニング業界と多岐に渡り応用の利くボイラー用の燃料混合装置が提案されている。
Among the fossil fuels currently used as fuel, petroleum is low in price but has a high carbon content, so there is a problem in terms of CO2 emissions. LP gas with a lower carbon content has a low CO2 emissions. Although there were few, the price tended to be high.
Looking at the recent situation, there is no price difference than before, and there is anxiety about stable supply. To solve this point, improve the combustion efficiency by mixing LP gas with hydrogen / oxygen gas or hydrogen gas alone, Aiming to reduce emissions of greenhouse gases such as carbon dioxide and reduce fuel costs, fuel mixers for boilers that have a wide range of applications in the food industry, agriculture / industrial use, construction industry, and cleaning industry have been proposed.
たとえば特許文献１では、ブラウンガス（酸素と水素を体積比１：２の比率で含む混合ガス）に、揮発性有機化合物ガス、酸素ガス、可燃性有機化合物ガスなどを均一に混合する方法として、液体状有機化合物を内部に収納した混合槽の下方から、ブラウンガス、酸素ガス、可燃性有機化合物ガスなど供給して、気泡を発生させ、気泡同士が融合して大型化した後に破壊し、かつ隔壁部の細孔を通過することによって混合ガスを得る方法が発明されている。
For example, in Patent Document 1, as a method of uniformly mixing a volatile organic compound gas, an oxygen gas, a flammable organic compound gas, or the like with brown gas (a mixed gas containing oxygen and hydrogen at a volume ratio of 1: 2), Supply brown gas, oxygen gas, flammable organic compound gas, etc. from below the mixing tank containing the liquid organic compound, generate bubbles, break up after the bubbles are fused and enlarged, and A method of obtaining a mixed gas by passing through the pores of the partition wall has been invented.
従来の液体状有機化合物内にガスを気泡として供給して混合する方法では、以下のような問題があった。
（１）ガス流量を増やすと、気泡の融合過程が不安定になるおそれがあるので、混合ガスの生産効率を高くできない。
（２）液面高さで混合効率が変化するので揮発性有機化合物の液面高さを制御する必要がある。
（３）温度によって混合ガス中の揮発性有機化合物濃度が変化するので混合容器内の温度制御を正確に行う必要がある。
（４）揮発性有機化合物としてプロパンガス等を使用するには、液化するために混合槽を高圧容器にする必要があり、装置が高価になる。
The conventional method of supplying and mixing gas as bubbles in a liquid organic compound has the following problems.
(1) When the gas flow rate is increased, the bubble fusion process may become unstable, so the production efficiency of the mixed gas cannot be increased.
(2) Since the mixing efficiency varies depending on the liquid level, it is necessary to control the liquid level of the volatile organic compound.
(3) Since the concentration of the volatile organic compound in the mixed gas varies depending on the temperature, it is necessary to accurately control the temperature in the mixing container.
(4) In order to use propane gas or the like as the volatile organic compound, the mixing tank needs to be a high-pressure vessel in order to liquefy, and the apparatus becomes expensive.
本発明は従来の混合装置の上記のような問題点を解決することであり、液体を使用せず、ガスのみを供給することにより、安全に、効率良く、安定した混合比で均一な混合ガスが得られる気体混合装置を低コストで提供することである。
The present invention is to solve the above-mentioned problems of the conventional mixing apparatus, and by supplying only gas without using a liquid, a uniform mixed gas can be obtained safely, efficiently and with a stable mixing ratio. Is to provide a gas mixing device at a low cost.
炭化水素ガスと水素ガスと酸素ガス、または炭化水素ガスと水素ガスを所定の割合で混合する装置であり、混合容器内に該容器の下方から前記ガスを供給管を介してそれぞれ注入し、各供給管が混合容器内に開口する先端部に多孔質通気性材料を設置することによりガスの拡散・混合を促進した。 A device that mixes hydrocarbon gas and hydrogen gas and oxygen gas or hydrocarbon gas and hydrogen gas at a predetermined ratio, and injects the gas into the mixing container from below the container through a supply pipe, Gas diffusion / mixing was promoted by installing a porous air-permeable material at the tip where the supply pipe opens into the mixing vessel.
前記供給管の先端に設けた各多孔質通気性材料の上方に、それぞれ、ガス流によって自転する軸流羽根車を設置することにより、更にガスの拡散・混合を促進した。 Gas diffusion / mixing was further promoted by installing an axial-flow impeller that rotates by a gas flow above each porous air-permeable material provided at the tip of the supply pipe.
混合容器内に、ガスを供給するすべての供給管の先端部の上部全体を覆う１つの上に窄まったじょうご状のホッパーを設け、ホッパーの天部にステンレス製の平織金網を張ることにより、ガスの混合状態を更に均一になるようにした。 In the mixing vessel, a funnel-shaped hopper that is constricted on the top of the top of all the supply pipes that supply gas is provided, and a stainless steel plain woven wire mesh is stretched on the top of the hopper, The gas mixing state was made more uniform.
前記混合容器内に供給する炭化水素ガスは圧縮されたボンベから供給され、該ボンベから前記混合容器の配管途中でベーパーライザーにより強制気化され、水素ガスと酸素ガスは前記炭化水素ガスの容器内圧力より約０.０１ＭＰａだけ高い圧力で前記容器内に導入した。 The hydrocarbon gas supplied into the mixing container is supplied from a compressed cylinder, and is forcedly vaporized from the cylinder by a vaporizer in the middle of the piping of the mixing container, and the hydrogen gas and oxygen gas are the pressure in the container of the hydrocarbon gas. It was introduced into the vessel at a pressure higher than about 0.01 MPa.
混合容器内に液体が存在しないので液面管理等が不要であり、非常にシンプルな構造のガス混合装置を得ることができ、ボイラー等燃焼装置に混合ガスを安定供給し連続運転することができる。
ガス供給管の先端に多孔質通気性材料（焼結金属など）を設けることにより、供給ガス圧によって供給ガスが多方向に向かって分散するので容器内ガスとの拡散・混合が促進される。
Since there is no liquid in the mixing container, liquid level control is not required, and a gas mixing device with a very simple structure can be obtained, and the mixed gas can be stably supplied to a combustion device such as a boiler and continuously operated. .
By providing a porous air-permeable material (sintered metal or the like) at the tip of the gas supply pipe, the supply gas is dispersed in multiple directions by the supply gas pressure, so that diffusion and mixing with the gas in the container is promoted.
前期多孔質通気性材料の上方に、ガス流によって自転する軸流羽根車を設置することにより、更にガスの拡散・混合が促進される。軸流式の羽根車は自転式なので動力の供給が不要であり、従って引火等の危険がない。 By installing an axial-flow impeller that rotates by the gas flow above the porous air-permeable material, gas diffusion and mixing are further promoted. Since the axial-flow impeller is a self-rotating type, no power supply is required, and therefore there is no danger of ignition.
ガスの供給管の上部全体を覆うホッパーを設け、ホッパーの天部にステンレス製の平織金網を張ることにより、ガスの混合状態が更に均一になる。
複数のガスが供給された場合に、すべての種類のガスが一旦ホッパーの内部に集まり上昇して、網目を通過する際に渦が発生し、混合が促進される。
By providing a hopper that covers the entire upper portion of the gas supply pipe, and by attaching a stainless steel plain woven wire mesh to the top of the hopper, the gas mixing state becomes more uniform.
When a plurality of gases are supplied, all types of gases once gather inside the hopper and rise, and vortices are generated when passing through the mesh, thereby promoting mixing.
混合装置内に供給する各ガスの圧力を制御することにより、流量、混合比がコントロールできるので制御システムをシンプルにできる。
また、混合容器内の圧力も低く設定できるので安全性が高く、低コストで製作可能である。
By controlling the pressure of each gas supplied into the mixing apparatus, the flow rate and mixing ratio can be controlled, so that the control system can be simplified.
Further, since the pressure in the mixing container can be set low, the safety is high and the production can be made at low cost.
以上のことを次の通り図面に基づき説明する。
図１において本発明における炭化水素ガスの混合・燃焼システムは、水素・酸素ガスもしくは水素ガス単体の生成装置とＬＰガス供給装置（バルク含む）の複数種類のガスを混合させる気体混合装置から成り、筒内で混合されたガスを鋼管にてバーナーに送り、汎用のガスボイラーにて安全にかつ安定して燃焼する。
The above will be described with reference to the drawings as follows.
In FIG. 1, the hydrocarbon gas mixing / combustion system according to the present invention is composed of a hydrogen / oxygen gas or hydrogen gas single generating device and a gas mixing device that mixes a plurality of types of LP gas supply devices (including bulk). The gas mixed in the cylinder is sent to the burner with a steel pipe and burned safely and stably in a general-purpose gas boiler.
前述水素・酸素ガスもしくは水素ガス単体の生成装置は水の電気分解装置であり、電極の形状と枚数、電気分解槽の構造を充分考慮し、水酸化カリウム溶液の濃度を調合し効率よく電気分解させる。この時の電流値も電気分解ガス生成に大きく作用する事と温度管理が大切であり、発生したガスは逆火性は強いが混合ガスとして燃焼させる場合は安全なガスではあり念の為に乾式安全器、水封安全器を設置し減圧されたガスにして燃焼させる。燃焼圧、消費量については燃焼器の能力を充分検討、考慮し安定したガス供給を行う事とする。 The above hydrogen / oxygen gas or hydrogen gas generator is an electrolysis device for water, and it takes into account the shape and number of electrodes and the structure of the electrolysis tank, and prepares the concentration of potassium hydroxide solution for efficient electrolysis. Let The current value at this time also has a large effect on the generation of electrolysis gas and temperature control is important. The generated gas is strong in flashback, but it is a safe gas to burn as a mixed gas. Install a safety device and a water seal safety device and burn it as a decompressed gas. With regard to combustion pressure and consumption, a stable gas supply will be provided after careful consideration and consideration of the combustor capacity.
電気分解された水素・酸素ガスもしくは水素ガス単体を安定して生成させる為に、電気分解液（電解質水溶液）の濃度を一定に、温度を60℃以下に安定させるべく冷却ファンを用いて一定温度を保ち、混合ガス生成時に圧力、容量を圧力調整器とフロート流量計もしくはタービンメーターを取り付けてバランスよく燃焼ガスの安定的な供給を図る。 In order to stably generate electrolyzed hydrogen / oxygen gas or hydrogen gas alone, use a cooling fan to keep the concentration of the electrolysis solution (electrolyte aqueous solution) constant and the temperature below 60 ° C. The pressure and capacity when the mixed gas is generated are attached with a pressure regulator and a float flow meter or turbine meter to ensure a stable supply of combustion gas in a well-balanced manner.
既存のＬＰガスに対し酸素・水素ガスもしくは水素ガス単体を混合させる事によりそれぞれが持つ燃焼特性を生かし、高温かつ完全燃焼させることによりボイラーの燃焼効率の向上と燃料の高効率化及び高燃焼を図ることにより一酸化炭素、二酸化炭素排出量の抑制と削減、省エネルギーに繋がるガス混合器と燃焼システムである。 Mixing oxygen / hydrogen gas or hydrogen gas alone with existing LP gas makes the best use of the combustion characteristics of each gas, improving the combustion efficiency of the boiler and increasing the fuel efficiency and combustion by high temperature and complete combustion. It is a gas mixer and a combustion system that lead to suppression and reduction of carbon monoxide and carbon dioxide emissions and energy saving.
主燃料ＬＰガスは液化ガスである為に大量消費、連続燃焼させる場合は強制気化装置（ベーパーライザー）を設置して安定供給し、酸素・水素ガスもしくは水素ガス単体は水を電気分解し生成する。それぞれ別系統から取入れ二種類のガスを混合させるべく筒状の気体混合装置に注入しLPガスと酸素・水素ガス及び水素ガス単体の混合ガスを生成させ混合器の内部にスムーズに混合ならしめる機能を持つ。 Since the main fuel LP gas is a liquefied gas, when it is consumed in large quantities and continuously burned, a forced vaporizer (vaporizer) is installed and stably supplied, and oxygen / hydrogen gas or hydrogen gas alone is generated by electrolyzing water. . A function that mixes two types of gas from different systems and injects them into a cylindrical gas mixing device to produce a mixed gas of LP gas, oxygen / hydrogen gas, and hydrogen gas alone, and smoothly mix them inside the mixer. have.
前項の気体混合装置には安全弁、逆止弁、圧力計を設け常に安全の確保に努めるとものとし、２〜３系列のガスをそれぞれのガス圧力を利用して取り入れることとするが、この時LPガス圧を基準にしてアシストガス（水素・酸素ガスもしくは水素ガス単体）は圧力スイッチを用いて間欠注入する。注入時間は３０秒以内、圧力はLPガス0.07MPa〜0.12MPa、酸素・水素ガス0.12MPa〜0.15MPa以下とする。
間欠注入することによって、注入する酸素・水素ガスは、ＬＰガスより０．０１ＭＰａ〜０．０５ＭＰａだけ高い圧力に設定でき、ガスの混合比は注入と停止のインターバル比を調節することにより制御することができる。
The gas mixing device in the previous paragraph shall be equipped with a safety valve, check valve and pressure gauge, and shall always strive to ensure safety, and two to three series of gases will be taken in using each gas pressure. Assist gas (hydrogen / oxygen gas or hydrogen gas alone) is intermittently injected using a pressure switch based on LP gas pressure. The injection time is 30 seconds or less, the pressure is LP gas 0.07 MPa to 0.12 MPa, and oxygen / hydrogen gas 0.12 MPa to 0.15 MPa or less.
By injecting intermittently, the oxygen / hydrogen gas to be injected can be set to a pressure higher by 0.01 MPa to 0.05 MPa than the LP gas, and the gas mixing ratio should be controlled by adjusting the interval ratio between injection and stop. Can do.
それぞれのガス入口を混合装置の下部に設け、多孔質通気性材料（軽石、セラミック、特殊金属・アルミナ等の焼結材など）で分散放出し、さらに混合させるべく軸流羽根車を各多孔質通気性材料の上部に設置し、その大きさは口径に応じたサイズに設定し、更にホッパー（ステンレス製平織り金網付）を１個、最良の窄み角度に決めて設置し、混合ガスとして所定の圧力に減圧しガスバーナーに送り燃焼する。この段階で混合されたガスは一定時間混合器の中にあり完全な混合ガスとして燃焼消費されることになる。 Each gas inlet is installed in the lower part of the mixing device, dispersed and discharged with porous breathable materials (pumice, ceramic, special metals, sintered materials such as alumina), and each axial impeller to be further mixed Installed on the top of the breathable material, the size is set according to the caliber, and one hopper (with a stainless steel plain weave wire mesh) is set at the best constriction angle and specified as a mixed gas The pressure is reduced to the pressure of the gas and burned by sending it to the gas burner. The gas mixed at this stage remains in the mixer for a certain period of time and is burned and consumed as a complete mixed gas.
実施例では多孔質通気性材料として厚さ3mmの焼結金属を使用し、空隙率30％以上、見かけ比重４．０以上ののものを半円形SUS材に溶接し消費量に応じて直径20mm〜90mmの形状にて設置数を増減させ、配管径サイズも同様に比例させるものとし、各系列ごとに逆止弁、ストップ弁を設け差圧による逆流を防止するものとする。連続運転に入ればガスバーナーで混合ガスが燃焼するため逆流することはない。 In this example, a sintered metal having a thickness of 3 mm is used as the porous air-permeable material, and a material having a porosity of 30% or more and an apparent specific gravity of 4.0 or more is welded to a semicircular SUS material, and the diameter is 20 mm according to consumption. The number of installations will be increased or decreased in the form of ~ 90mm, and the pipe diameter size will be made proportional as well, and a check valve and stop valve will be provided for each series to prevent backflow due to differential pressure. If the continuous operation is started, the mixed gas burns in the gas burner, so there is no backflow.
ボイラーの消費量にもよるが気体混合装置は呼径300A〜500A×1300L（円筒状の外形３１８．５ｍｍ〜５０８ｍｍ、高さ１３００ｍｍ）、厚さ3mm程度のSUS製円筒材を使用し、上部フランジに取出弁、安全弁、圧力計、温度計、サンプリングガス採取弁を設け、下部フランジには各ラインにストップ弁、逆止弁、多孔資通気性材料を取付け差圧によってガスを筒内に送り混合ガスとする。導入配管及びガス混合装置については漏洩を防止する為に溶接仕上げとする。また念の為に下部フランジにドレン抜弁を取り付けておく事とする。 Depending on the boiler consumption, the gas mixing device uses a SUS cylindrical material with a nominal diameter of 300A to 500A x 1300L (cylindrical outer shape 318.5mm to 508mm, height 1300mm) and a thickness of about 3mm. Are provided with a take-off valve, safety valve, pressure gauge, thermometer, sampling gas sampling valve, and a stop valve, check valve and porous air-permeable material are attached to each line on the lower flange, and gas is fed into the cylinder by differential pressure and mixed Use gas. The introduction pipe and gas mixing device shall be welded to prevent leakage. As a precaution, a drain valve is attached to the lower flange.
混合ガス体だけの燃焼時には一旦ブロアーの空気調整が出来れば少量の過剰空気で完全に安定燃焼して安全であるが、水素ガスは爆発限界濃度の範囲が広く逆火性が強く安全性考慮の観点から水封安全器、乾式安全器の二段構えとし、更に電気分解槽には安全弁や破裂板を取り付け静電気除去の手段を講じ、常に災害防止に努める。 When the air conditioning of the blower can be adjusted once when only the mixed gas body is combusted, it is safe to burn completely stably with a small amount of excess air, but hydrogen gas has a wide range of explosive limit concentrations and is strong in flashback, taking safety into consideration. From the point of view, a water-sealed safety device and a dry safety device are used in two stages, and a safety valve and a rupture disk are attached to the electrolysis tank, and measures are taken to eliminate static electricity.
水の電気分解装置で得られた水素・酸素ガスもしくは水素ガス単体は燃焼時に二酸化炭素を発生せず窒素化合物を抑え、またＬＰガスに添加する事により二酸化炭素排出量削減及び高燃焼かつ完全燃焼させる事により高カロリーの確保と燃料費削減にも寄与する効果は大きく安定した燃料が供給出来る。 Hydrogen / oxygen gas or hydrogen gas obtained by water electrolyzer does not generate carbon dioxide during combustion, suppresses nitrogen compounds, and is added to LP gas to reduce carbon dioxide emissions and achieve high combustion and complete combustion By doing so, the effect that contributes to securing high calories and reducing fuel costs can be greatly supplied.
二種類の気体をより効率よく混合生成する為に、多孔質通気性材料の出口上部に動力を使用せずにガスの流速だけで軸流羽根車を回転させ効率よく混合させる方法をとり、安定した混合ガスの生成をさせるべく軸流羽根車は樹脂製とし、上下二箇所のベアリングにより軽量、高速回転させることにより混合性の高いガスが出来ることになる。 In order to mix and generate two types of gas more efficiently, a method of rotating the axial flow impeller only by the gas flow velocity and mixing efficiently without using power at the upper outlet of the porous breathable material is stable. In order to generate the mixed gas, the axial-flow impeller is made of resin, and a gas with high mixing property can be produced by rotating lightly and at high speed with two upper and lower bearings.
実証時の条件として、本発明によるガス混合装置で混合した混合ガスの燃焼排気ガスを測定の結果、燃料費は現在10％程度、一酸化炭素10%以下、二酸化炭素は8％以下程度の減少が確認され、今後の実証の中で高燃焼、高カロリーの混合点を追及する事により窒素化合物等測定可能な限り排出ガス削減の効果を見つけ、更なる温室効果ガスの削減と燃料費削減に貢献できる事が証明された。
As a condition for the demonstration, as a result of measuring the combustion exhaust gas of the mixed gas mixed with the gas mixing device according to the present invention, the fuel cost is currently reduced by about 10%, carbon monoxide is 10% or less, and carbon dioxide is reduced by about 8% or less. In the future demonstration, by pursuing the mixing point of high combustion and high calorie, we found the effect of reducing exhaust gas as much as possible by measuring nitrogen compounds etc., and further reducing greenhouse gas and fuel cost Proven to contribute.
