Description

本考案は、過熱水蒸気含有ガスの製造技術に係り、特に高温度の過熱水蒸気含有ガスを大量にかつ容易に製造する装置に関する。 The present invention relates to a technology for producing superheated steam-containing gas, and more particularly to an apparatus for easily producing a large amount of superheated steam-containing gas at high temperature.

従来の高温水蒸気含有気体の製造方法では、まず水蒸気を作り、その水蒸気を加熱しているので、高温過熱水蒸気の製造には難があった。すなわち、高温水蒸気含有気体、例えば過熱水蒸気含有気体を製造するには、水を蒸発させて水蒸気とし、生成した水蒸気を鉄管等の中を通しながら外側から加熱して温度を上げ、過熱水蒸気とする方法がとられている。また、水蒸気の過熱手段として高周波誘導加熱方法などが広く採用されている。しかし、これらの方法ではエネルギー損失が大きく、また高価な電気エネルギーを必要とするため、装置材料や設備の点でコストが掛かる問題があった。 In the conventional method for producing a high-temperature steam-containing gas, since steam is first produced and heated, it has been difficult to produce high-temperature superheated steam. That is, in order to produce a high-temperature steam-containing gas, for example, a superheated steam-containing gas, water is evaporated into steam, and the generated steam is heated from the outside while passing through an iron pipe or the like to raise the temperature and become superheated steam. The method is taken. Further, a high frequency induction heating method or the like has been widely adopted as a means for superheating steam. However, these methods have a problem in that the energy loss is large and expensive electric energy is required, so that the cost is high in terms of equipment materials and equipment.

また、以前に本願考案者らは、炉内で燃料を酸素含有ガスで燃焼させて高温となし、その炉内に水又は水蒸気を分散供給して過熱水蒸気含有ガスを生成させて炉外へ取り出し、次いで前記過熱水蒸気含有ガスを前記炉に隣接して設けられた調整室に導入した後、同調整室内に水又は水蒸気を分散・供給して、水蒸気含有ガスの温度又は水蒸気含有量を調整した過熱水蒸気含有ガスの製造技術を提案した。 Further, the inventors of the present application previously burned the fuel in the furnace with the oxygen-containing gas to bring it to a high temperature, dispersedly supplying water or steam into the furnace to generate the superheated steam-containing gas, and taking it out of the furnace. Then, after introducing the superheated steam-containing gas into a control chamber provided adjacent to the furnace, water or steam is dispersed and supplied into the control chamber to adjust the temperature of the steam-containing gas or the steam content. A manufacturing technology of superheated steam-containing gas was proposed.

昨今、過熱水蒸気の高温での利用分野は広がっており、さらなる低コスト化による一定温度の過熱水蒸気の製造方法が待望されている。 Recently, the field of application of superheated steam at high temperatures is expanding, and a method for producing superheated steam at a constant temperature by further cost reduction is desired.

しかし、従来の高温水蒸気含有気体の製造方法では、まず水蒸気を作り、その水蒸気をさらに加熱して高温過熱水蒸気を得ているので、その製造装置が複雑であり、エネルギー損失が大きい。また、過熱手段に高周波誘導加熱装置を採用するものでは、高価な電気エネルギーを大量に必要とし、その装置を構成する材料や構造の複雑さがコスト高の原因となり、得られる一定温度の水蒸気含有気体の温度にばらつきが起こりやすいという問題があった。 However, in the conventional method for producing a gas containing high-temperature steam, first, steam is produced, and the steam is further heated to obtain high-temperature superheated steam, so that the production apparatus is complicated and energy loss is large. Further, in the case of adopting a high frequency induction heating device for the superheating means, a large amount of expensive electric energy is required, and the complexity of the material and structure constituting the device causes high cost. There is a problem that the temperature of the gas tends to vary.

本考案では燃焼ガスそのものを過熱水蒸気として取出し、取り出した過熱水蒸気の用途に応じた適温に下げるための制御を行う。 これによれば、設備費も安く、製造コストも従来の方法に比べて大幅にダウンさせることができる。 In the present invention, the combustion gas itself is taken out as superheated steam, and control is performed to lower the temperature of the taken out superheated steam to an appropriate temperature according to the application. According to this, the equipment cost is low, and the manufacturing cost can be significantly reduced as compared with the conventional method.

さらに、従来技術では難しいとされていた高温過熱水蒸気も安価に製造し、供給できる様になり、ダイオキシンを含む有害物の分解、殺菌処理、食品残滓処理、食材の焙煎処理、廃棄物の安全処理、悪臭ガスの分解等様々な用途が開けてくる。 Furthermore, high temperature superheated steam, which was considered difficult with conventional technology, can now be manufactured and supplied at low cost, and decomposition of harmful substances including dioxins, sterilization, food residue treatment, roasting of foodstuffs, safety of waste Various applications such as treatment and decomposition of malodorous gas will be opened.

本考案では、1,000℃〜1,200℃の過熱水蒸気の製造には、(1)水電解ガス(例えば、ブラウンガス、オーマサガス等)の燃焼、(2)酸水素ガス燃焼(水素を酸素で燃焼させる)があるが、これらは燃焼ガス自体が過熱水蒸気であるので、そのまま使えば良い。 In the present invention, (1) combustion of water electrolysis gas (for example, brown gas, omasa gas, etc.), (2) oxyhydrogen gas combustion (hydrogen is converted to oxygen) for production of superheated steam at 1,000°C to 1,200°C. However, since the combustion gas itself is superheated steam, it can be used as it is.

燃焼温度は3,000℃とも言われているので、燃焼温度を下げる方法が必要となる。燃焼温度を下げる方法としては、水蒸気を水電解ガスに混ぜて燃焼するか、アルコールを通してアルコール蒸気で燃焼を緩和させる。 Since the combustion temperature is said to be 3,000°C, a method of lowering the combustion temperature is needed. As a method for lowering the combustion temperature, water vapor is mixed with water electrolysis gas for combustion, or alcohol is passed through alcohol to moderate combustion.

1,000℃又はそれ以下の過熱水蒸気の製造には、前記(1)及び(2)の高温ガスに水を噴射して温度を下げる方法もあるが、経済的な方法として、(3)プロパン酸素バーナで炉体を加熱し、800℃に達した後アルコール水溶液(例えば、メタノール水溶液)を噴射すると温度は200℃上がり、1,000℃の加熱水蒸気が得られる。
この過熱水蒸気に水を適当量噴射すると水の蒸発熱539kcal/kgと適温の水蒸気に温度を上げる熱量に使われることで、その熱量分、加熱水蒸気温度が下がる。
この様にして適温に下げられた過熱水蒸気に噴射した水が過熱水蒸気として加えられて、使用される。
In the production of superheated steam at 1,000° C. or lower, there is also a method of lowering the temperature by injecting water into the high temperature gas of the above (1) and (2), but as an economical method, (3) propane When the furnace body is heated with an oxygen burner and the temperature reaches 800°C, an aqueous alcohol solution (for example, an aqueous methanol solution) is injected to raise the temperature by 200°C, and heated steam at 1,000°C is obtained.
By injecting an appropriate amount of water into this superheated steam, the heat of vaporization of water is used as 539 kcal/kg and the amount of heat used to raise the temperature to an appropriate temperature of steam, and the heating steam temperature is reduced by that amount of heat.
The water thus jetted to the superheated steam cooled to an appropriate temperature in this manner is added as superheated steam and used.

普通プロパン酸素バーナでは酸素リッチで燃焼させるが、噴射するアルコール水溶液には特に酸素は供給せず、プロパンの酸化に使われて残った酸素がアルコールの酸化に使用される。この時、残存酸素量がアルコールの酸化に不足の場合アルコールは熱分解し、例えばCH3OH→CO+2H2となり、生成したCOは更に圧倒的多量の過熱水蒸気の中で水性ガスシフト反応を起こし、
CO+H2O→CO2+H2
となり、還元性の過熱水蒸気となる。そして65〜75%過熱水蒸気が得られる。
Normally, a propane oxygen burner burns with rich oxygen, but oxygen is not particularly supplied to the injected alcohol aqueous solution, and the remaining oxygen used for the oxidation of propane is used for the oxidation of alcohol. At this time, when the amount of residual oxygen is insufficient for the oxidation of alcohol, the alcohol is thermally decomposed, for example, CH 3 OH→CO+2H 2 , and the produced CO causes a water gas shift reaction in an overwhelmingly large amount of superheated steam,
CO+H 2 O → CO 2 +H 2
And becomes reducing superheated steam. And 65-75% superheated steam is obtained.

(4)酸素・灯油(重油)バーナ+アルコール水溶液
前記(3)の酸素プロパンバーナ+アルコールと同様に1,000℃の過熱水蒸気が得られる。それから、温度を下げて適温の過熱水蒸気を得る。そして、60%〜70%過熱水蒸気が得られる。
(4) Oxygen/kerosene (heavy oil) burner+alcohol aqueous solution Superheated steam at 1,000° C. is obtained in the same manner as the oxygen propane burner+alcohol of (3) above. Then, the temperature is lowered to obtain superheated steam at an appropriate temperature. And 60%-70% superheated steam is obtained.

(5)酸素富化・灯油(重油)バーナ+アルコール水溶液
ほぼ前記(3)(4)と同様であるが酸素中に含まれる窒素量によって過熱水蒸気濃度が決定される。
(5) Oxygen enrichment/kerosene (heavy oil) burner+alcohol aqueous solution Almost the same as (3) and (4) above, but the superheated steam concentration is determined by the amount of nitrogen contained in oxygen.

The third burner 2'is connected to the second burner at the switch 201 so that it can be used when another combustion gas is used.

例えば、第1バーナ1をプロパン酸素バーナとしてプロパンガスと酸素含有ガス(例えば、空気)を燃焼室4内に導入して燃焼させ、700℃以上の高温に加熱する。 For example, using the first burner 1 as a propane oxygen burner, propane gas and oxygen-containing gas (for example, air) are introduced into the combustion chamber 4 and burned, and heated to a high temperature of 700° C. or higher.

次いで、第2バーナ2からアルコール水(例えば、メタノール30%水溶液)を高温の燃焼室4内に噴射して燃焼する。この段階で、アルコール水はアルコールの燃焼と水分の微爆発による燃焼によって、より高温に加熱される。
その後、より高温に加熱されたガスは連通路6を経て過熱水蒸気調整室5に導入される。
Next, alcohol water (for example, a 30% aqueous solution of methanol) is injected from the second burner 2 into the high temperature combustion chamber 4 and burned. At this stage, the alcoholic water is heated to a higher temperature by the combustion of alcohol and the combustion of a slight explosion of water.
Then, the gas heated to a higher temperature is introduced into the superheated steam adjusting chamber 5 through the communication passage 6.

過熱水蒸気調整室5の内部に、噴射ノズル3(3a,3b)から水又は水蒸気が噴射供給され、連通路6から流入した高温ガスに混入される。この段階で、水又は水蒸気等は直ちに気化して高温の過熱水蒸気となる。最後に、得られた過熱水蒸気は過熱水蒸気導出口9から外部の利用機器へ導出される。 Water or steam is injected and supplied from the injection nozzle 3 (3a, 3b) into the superheated steam adjusting chamber 5, and is mixed with the high temperature gas flowing from the communication passage 6. At this stage, water, steam or the like is immediately vaporized to become high temperature superheated steam. Finally, the obtained superheated steam is led out to the external equipment from the superheated steam outlet 9.

なお、燃焼室4内には、例えばセラミックハニカム製の発熱板7が配置されており、燃焼室4内の高温状態が温度変動なくして安定に保持される。
燃焼室4、連通路6に装設された温度計T1,T2は、燃焼室4の燃焼制御に用いられる。
