Description

本発明は、過熱水蒸気の生成技術に関し、特に大量の過熱水蒸気を容易に生成させる技術の提供に関する。    The present invention relates to a technique for generating superheated steam, and more particularly to providing a technique for easily generating a large amount of superheated steam.

過熱水蒸気は有害成分を含まない高温蒸気であるため食品の殺菌・滅菌用等に好適に用いられている。
過熱水蒸気を発生させる技術としては、例えば特開平８−１３５９０３号公報に開示されるものがあり、コイルに交流電流を流して金属体を電磁誘導で発熱させ、水蒸気をその発熱体表面に接触流通させることで１００℃以上の水蒸気（過熱水蒸気）を発生させる。その他の技術としては例えば特開平９−２４１７３４号公報に示されるごとく、蒸気ボイラーで水を蒸発させ、さらにその蒸発した水蒸気を、燃料の燃焼により高温に加熱するものである。
しかしながら、従来の電磁誘導加熱の技術では、高温の過熱水蒸気を大量に生成させることが容易でなく、また高圧の過熱水蒸気を生成させることも難しかった。Superheated steam is a high-temperature steam that does not contain harmful components, and is therefore suitably used for food sterilization and sterilization.
As a technique for generating superheated steam, for example, there is a technique disclosed in Japanese Patent Application Laid-Open No. 8-135903. An alternating current is supplied to a coil to heat a metal body by electromagnetic induction, and the steam is circulated on the surface of the heating element. By doing so, water vapor (superheated water vapor) of 100 ° C. or higher is generated. As another technique, for example, as disclosed in JP-A-9-241734, water is evaporated by a steam boiler, and the evaporated water vapor is heated to a high temperature by combustion of fuel.
However, with the conventional electromagnetic induction heating technology, it is not easy to generate a large amount of high-temperature superheated steam, and it is also difficult to generate high-pressure superheated steam.

本願発明をより詳細に説述するため、添付の図面に基づいて説明する。
図１は、本願発明実施例の過熱蒸気生成装置の概略説明図を示すものであり、図２は通気性非加熱体の実施例を示す図である。
図中、１は筒状体、１ａは筒状体の一方端、１ｂは筒状体の他方端、２は噴射水の導入ノズル、３は過熱蒸気の噴出口である。また、４は通気性被加熱体、５は励磁コイル、６は被覆材、７は導管、８は加圧水蒸気発生装置、４０はパンチングメタル板である。なお、ＨＶは過熱蒸気、Ｖ１、Ｖ２は開閉弁、Ｖ３、Ｖ４は逆止弁である。
図１において、導電体材料製の筒状体１の一方端１ａには噴射水の導入ノズル２を備え、他方端１ｂには過熱蒸気の噴出口３を備えている。
筒状体１は外周面がキャスタブル耐火物セラミックス製の被覆材６で覆われ、断熱されている。そして、そのセラミックス被覆材６の外周面に高周波電流を通電する励磁コイル５が巻回され、図示しない高周波電流電源に接続されている。
また、筒状体１内には導電体材料製の通気性被加熱体４（図１においてはステンレススチール製の球体（図２（ａ）参照））が装填されており、励磁コイル５による電磁誘導で発熱加熱され、そこを通過する水又は水蒸気が高温加熱されて過熱蒸気ＨＶとなって、他方端１ｂの噴出口３から噴出する。４０はパンチングメタル板である。
なお、筒状体１の一方端１ａに設けられている噴射水の導入ノズル２は、導管７を経由して送水ポンプＰに接続され、また、加圧水蒸気発生装置８に接続されている。
噴射水の導入ノズル２から筒状体１内へ噴射水を噴射するには、加圧水蒸気発生装置８からの導管の途中に設けられた開閉弁Ｖ２を閉じ、開閉弁Ｖ１を開く。また、筒状体１内へ噴射水と加圧水蒸気を噴射するには、開閉弁Ｖ２を開き、開閉弁Ｖ１も開く。なお、Ｖ３及びＶ４は逆止弁である。
本願発明においては、導電体材料製の通気性被加熱体４が装填された筒状体１の一方端１ａから筒状体１内に水又は水及び水蒸気を噴射し、次いで同筒状体１内に装填された前記通気性被加熱体４を水又は水蒸気が通過する。その際、前記通気性被加熱体４が励磁コイル５による電磁誘導で発熱加熱されているので、そこを通過する水又は水蒸気は高温加熱されて、筒状体１の他方端１ｂの噴出口３から過熱蒸気ＨＶとなって噴出する。
なお、４０はパンチングメタル板である。前記パンチングメタル４０は、筒状体１内に装填された前記通気性被加熱体４が筒状体１の外に流出するのを防止している。また、４１はパンチングメタル板製押さえ具であるが、熱伝導性が高く、耐熱性の良いもの（例えば銅又は銀製）が好ましく、この場合銅製で、上下二重板構造であり、板４１ａと板４１ｂの間に架橋板４１ｃが結合された構造となっている。そして板４１ｂから長脚４１ｄが突設され、通気性被加熱体４・・・間に没入している。
したがって、常に通気性被加熱体４・・・の高熱が長脚４１ｄを伝わって４１ｂ、４１ｃ、４１ａを高温に維持し、噴射水の導入ノズル２から噴出された噴射水が温度低下することなく、直ちに、かつ継続的に蒸気化することが保証される。
水を噴射して同筒状体１内に装填された前記通気性被加熱体４を高周波誘導加熱すると、筒状体内に水蒸気を導入して加熱する場合に比べて、数１０倍〜１０００倍量程度の過熱水蒸気を発生することができる。よって高圧の過熱水蒸気を筒状体の他方端から容易に噴出せしめることができる。
すなわち、２２．４リットルの水蒸気は１８ｇであるが、１８ｍｌの水は１８ｇであるため、理論的には１８ｍｌの水を筒状体１内に噴射すれば、２２，４００ｍｌの水蒸気が生成することとなり、結局２２，４００ｍｌ÷１８ｍｌ≒１２４０、よって水を噴射加熱する場合は水蒸気を導入加熱する場合に比して約１２００倍もの大量の加圧水蒸気が生成することとなる。したがって、生成する加圧水蒸気の圧力も非常に高いものとなる。
なお、水又は水蒸気は、筒状体１内を通過する際に、加熱された通気性被加熱体４に接触し、さらに加熱されて過熱蒸気となり、徐々に膨張させられながら筒状体１の排出側へ臨ませられることになる。
筒状体１内の温度が上昇して励磁コイル５の電源を切っても、通気性被加熱体４が高温状態にあり、これが冷えることによって筒状体１内の温度が下がるため、冷却にも時間を要することになる。
通気性被加熱体４の導電体材料としては、鉄などの強い磁性の金属、ステンレス鋼のＳＵＳ４３０・ＳＵＳ４０３、ニッケル、チタン等の弱い磁性の金属の他、炭素、炭化ケイ素等のカーボンセラミックを使用することができる。
通気性被加熱体４の導電体材料としては、磁性金属材料、特に硬質磁性材料が特に好ましい。
通気性被加熱体４は、タンク内において蒸気を円滑に通過させる必要があり、棒体、線材、板材、ハニカム材、網体、球体、中空球体又は不定形塊状体等を使用することができる。それらには透孔を穿設しておいてもよい。
実施例：
図１に示す過熱蒸気生成装置（ただし、通気性被加熱体４としては図２（ｂ）に示す所々に開口部を有する中空球体のものを使用）を用いて、水から過熱水蒸気を発生させた。
まず、筒状体１の一方端の１ａ内に配置された噴射水の導入ノズル２から噴射水を噴射圧４〜６ｋｇ／ｃｍ２、６〜１０ｋｇ／ｈで噴射した。この時、加圧水蒸気発生装置８は使用せず、したがって開閉弁Ｖ２は閉とし、開閉弁Ｖ１は開とした。
筒状体１は内径２０ｃｍ、長さ４０ｃｍであり、被加熱体は磁性金属材料のフェライト系ステンレス鋼（ＳＵＳ４３０）、好ましい例では炭素鋼製を用い、筒状体１はオーステナイト系ステンレス鋼（ＳＵＳ３０４）製のものを使用した。
また、励磁コイル５に周波数２０ｋＨｚの高周波電流を２５〜３０ｋｗ／ｈで供給した。
その結果、過熱蒸気の噴出口３から３２０℃の高温の過熱水蒸気ＨＶが継続的に噴出した。The present invention will be described in more detail with reference to the accompanying drawings.
FIG. 1 is a schematic explanatory view of a superheated steam generator according to an embodiment of the present invention, and FIG. 2 is a view showing an embodiment of a breathable non-heated body.
In the figure, 1 is a cylindrical body, 1a is one end of the cylindrical body, 1b is the other end of the cylindrical body, 2 is an injection nozzle for jet water, and 3 is an outlet for superheated steam. Further, 4 is a breathable heated object, 5 is an exciting coil, 6 is a coating material, 7 is a conduit, 8 is a pressurized steam generator, and 40 is a punching metal plate. HV is superheated steam, V1 and V2 are on-off valves, and V3 and V4 are check valves.
In FIG. 1, a cylindrical body 1 made of a conductive material is provided with a jet water introduction nozzle 2 at one end 1a and a superheated steam jet 3 at the other end 1b.
The outer peripheral surface of the cylindrical body 1 is covered with a covering material 6 made of castable refractory ceramics to be thermally insulated. And the exciting coil 5 which supplies a high frequency current to the outer peripheral surface of the ceramic coating material 6 is wound and connected to a high frequency current power source (not shown).
In addition, a breathable heated body 4 made of a conductive material (in FIG. 1, a sphere made of stainless steel (see FIG. 2A)) is loaded in the cylindrical body 1, and electromagnetic waves generated by the excitation coil 5 are loaded. Heated and heated by induction, water or water vapor passing therethrough is heated to high temperature to become superheated steam HV, and is ejected from the ejection port 3 at the other end 1b. Reference numeral 40 denotes a punching metal plate.
The jet water introduction nozzle 2 provided at one end 1 a of the cylindrical body 1 is connected to the water supply pump P via the conduit 7 and is connected to the pressurized steam generator 8.
In order to inject the injected water into the cylindrical body 1 from the injection nozzle 2 of the injected water, the on-off valve V2 provided in the middle of the conduit from the pressurized steam generator 8 is closed and the on-off valve V1 is opened. Moreover, in order to inject spray water and pressurized water vapor into the cylindrical body 1, the on-off valve V2 is opened and the on-off valve V1 is also opened. V3 and V4 are check valves.
In the present invention, water or water and water vapor are injected into the cylindrical body 1 from one end 1a of the cylindrical body 1 loaded with the air-permeable heated body 4 made of a conductive material, and then the cylindrical body 1 Water or water vapor passes through the air-permeable heated body 4 loaded therein. At this time, since the air-permeable heated body 4 is heated and heated by electromagnetic induction by the exciting coil 5, the water or water vapor passing therethrough is heated at a high temperature, and the spout 3 at the other end 1b of the cylindrical body 1 is heated. From which it becomes superheated steam HV.
Reference numeral 40 denotes a punching metal plate. The punching metal 40 prevents the breathable heated body 4 loaded in the cylindrical body 1 from flowing out of the cylindrical body 1. Reference numeral 41 denotes a punching metal plate presser, which is preferably made of a material having high thermal conductivity and good heat resistance (for example, copper or silver). In this case, the plate is made of copper and has an upper and lower double plate structure. The bridge plate 41c is coupled between the plates 41b. And the long leg 41d protrudes from the board 41b, and is immersed between the air-permeable heated bodies 4.
Therefore, the high heat of the air-permeable heated body 4.. It is guaranteed to vaporize immediately and continuously.
When the air-permeable heated body 4 loaded in the cylindrical body 1 by jetting water is induction-heated by high frequency, it is several tens to 1000 times as compared with the case where water is introduced into the cylindrical body and heated. An amount of superheated steam can be generated. Therefore, high-pressure superheated steam can be easily ejected from the other end of the cylindrical body.
That is, although 22.4 liters of water vapor is 18 g, 18 ml of water is 18 g. Therefore, theoretically, if 18 ml of water is injected into the cylindrical body 1, 22,400 ml of water vapor is generated. As a result, 22,400 ml ÷ 18 ml≈1240. Therefore, when water is injected and heated, a large amount of pressurized water vapor is generated about 1200 times as much as when water vapor is introduced and heated. Therefore, the pressure of the generated pressurized steam is very high.
In addition, when water or water vapor passes through the cylindrical body 1, the water or steam contacts the heated breathable heated body 4 and is further heated to become superheated steam. You will face the discharge side.
Even if the temperature in the cylindrical body 1 rises and the power of the exciting coil 5 is turned off, the air-permeable heated body 4 is in a high temperature state. Will also take time.
As the conductive material of the breathable heated body 4, a strong magnetic metal such as iron, stainless steel SUS430 / SUS403, weak magnetic metal such as nickel and titanium, and carbon ceramic such as carbon and silicon carbide are used. can do.
As the conductor material of the breathable heated body 4, a magnetic metal material, particularly a hard magnetic material is particularly preferable.
The breathable heated body 4 needs to allow steam to pass smoothly through the tank, and a rod, wire, plate, honeycomb material, net, sphere, hollow sphere, or indefinite lump can be used. . They may be perforated.
Example:
Using the superheated steam generator shown in FIG. 1 (however, as the air-permeable heated body 4, hollow spheres having openings in the places shown in FIG. 2B are used), superheated steam is generated from water. It was.
First, spray water was sprayed at a spray pressure of 4 to 6 kg / cm 2 and 6 to 10 kg / h from a spray water introduction nozzle 2 disposed in one end 1 a of the cylindrical body 1. At this time, the pressurized steam generator 8 was not used, so the on-off valve V2 was closed and the on-off valve V1 was opened.
