Description
本発明は、永久磁石を用いて発生させた渦電流によりジュール熱を発生させて水や油を加熱して使用する電磁誘導加熱式ボイラーに関するものである。 The present invention relates to an electromagnetic induction heating boiler that uses Joule heat generated by an eddy current generated using a permanent magnet to heat water or oil.
従来から交流電流により交流磁界を発生させて行う誘導加熱の手法を用いた電磁誘導式加熱装置が種々提案されている。例えば、導電性の被加熱体と交流磁場発生手段から構成される誘導加熱装置において、直流磁場発生手段を永久磁石とし、この直流磁場に交流磁場を作用させることにより、被加熱体を急速に加熱するようにした誘導加熱装置(特許文献1参照)や渦電流が発生可能なロータリーの外周に複数の永久磁石を配置した加熱装置(特許文献2参照)等が提案されている。 Conventionally, various electromagnetic induction heating apparatuses using an induction heating method in which an alternating magnetic field is generated by an alternating current have been proposed. For example, in an induction heating apparatus composed of a conductive object to be heated and an AC magnetic field generating means, the DC magnetic field generating means is a permanent magnet, and the AC magnetic field is applied to this DC magnetic field to rapidly heat the object to be heated. An induction heating apparatus (see Patent Document 1) that is configured to be used, a heating apparatus in which a plurality of permanent magnets are arranged on the outer periphery of a rotary capable of generating eddy currents (see Patent Document 2), and the like have been proposed.
しかしながら、上記従来の装置は、複写機におけるトナーの定着や工業用材料の乾燥・加熱に応用したものであり、一般家庭における熱源や農業分野における加温装置としての応用例はほとんど無いのが実情である。 However, the above-mentioned conventional apparatus is applied to fixing toner in copying machines and drying / heating industrial materials, and there are almost no application examples as a heat source in general households or as a heating apparatus in the agricultural field. It is.
また、従来のボイラーとしては、伝熱部が熱媒体としての水や油を流通させる管になっている貫流式ポーラー、鋼鉄製の水を満たした缶を主体とした丸ボイラーは、保有水量が比較的大きく、負荷の変動に強い。その反面、立ち上がりが遅く、万一、爆発事故が起きれば被害は甚大である。
本発明は上記のような従来技術の課題に鑑み、簡単な構成で、一般家庭や農業分野において、高効率で、安全且つ経済的な熱源として有用な電磁誘導発熱式ボイラーを提供することを目的とするものである。In addition, conventional boilers have cross-flow polarities where the heat transfer section is a pipe that circulates water and oil as the heat medium, and round boilers mainly made of steel-filled cans. Relatively large and resistant to load fluctuations. On the other hand, the start-up is slow, and if an explosion happens, the damage is enormous.
SUMMARY OF THE INVENTION The present invention has been made in view of the above-described problems of the prior art, and has an object to provide an electromagnetic induction heating boiler that has a simple configuration, is highly efficient, and is useful as a safe and economical heat source in general households and agricultural fields. It is what.
この目的を達成するため、本発明の電磁誘導発熱式ボイラーは、内部に永久磁石が配置され、回転可能に設けられた平盤状回転体と、前記平盤状回転体の近傍に配置して設けられると共に、前記永久磁石による磁界中に配置された導電材を含む発熱部と、該発熱部に立設された複数の放熱体と、これら放熱体を覆うフード式の熱媒体貯留槽とからなることを第1の特徴とし、放熱体に近接して熱媒体としての水や油を流通させる管路を設けたことを第2の特徴とする。また、熱媒体貯留槽に熱媒体としての水や油を貯留し、発熱部及び放熱体で煮沸することを第3の特徴とする。 In order to achieve this object, an electromagnetic induction heating boiler according to the present invention includes a flat plate-like rotating body that is provided with a permanent magnet and is rotatably provided, and is disposed in the vicinity of the flat plate-like rotating body. A heat generating part including a conductive material disposed in the magnetic field by the permanent magnet, a plurality of heat dissipating members standing on the heat generating part, and a hood-type heat medium storage tank covering the heat dissipating elements This is a first feature, and a second feature is that a pipe for circulating water or oil as a heat medium is provided in the vicinity of the radiator. A third feature is that water or oil as a heat medium is stored in the heat medium storage tank and boiled by the heat generating part and the heat radiator.
本発明の電磁誘導発熱式ボイラーは、以下の優れた効果がある。
(1)渦電流により導電材料を発熱させる自己発熱なので、熱効率がよく、また二酸化炭素の発生がなく、エコロジカルな熱源である。また、使用する電力はロータの回転のみであり、電力消費量は少なく低コストである。
(2)ロータ内に永久磁石を配置し、導電材料の近傍で回転させるだけの簡単な構造なので、故障しにくく、メンテナンスもし易い。
(3)温度調整は、ロータの回転数の調整だけで済むので、容易である。
(4)放熱体に近接して熱媒体としての水や油を流通させる管路を設けたことにより、装置近傍におけるジュール熱の無駄な散逸を防止し、配管した所望の箇所を確実に加温することができる。The electromagnetic induction heating boiler of the present invention has the following excellent effects.
(1) Since it is self-heating that causes the conductive material to generate heat due to eddy currents, it has good thermal efficiency and does not generate carbon dioxide, and is an ecological heat source. Further, the electric power used is only the rotation of the rotor, and the electric power consumption is small and the cost is low.
(2) Since it is a simple structure in which a permanent magnet is arranged in the rotor and rotated in the vicinity of the conductive material, it is difficult to fail and easy to maintain.
(3) Temperature adjustment is easy because it is only necessary to adjust the rotational speed of the rotor.
(4) By providing a conduit for circulating water and oil as a heat medium in the vicinity of the radiator, wasteful dissipation of Joule heat in the vicinity of the device is prevented, and the desired location of piping is reliably heated. can do.
本発明では、金属板等の導電材の近傍に、強力な磁力を有する永久磁石を内部に配置した平盤状ロータを高速回転させることによって、導電材にN,Sの磁極が交互に横切り、その結果、電磁誘導現象により導電材自体には渦電流が発生し、この渦電流が熱エネルギーに変換されて導電材が発熱する。 In the present invention, N and S magnetic poles are alternately traversed in the conductive material by rotating at high speed a flat plate-like rotor in which a permanent magnet having a strong magnetic force is disposed in the vicinity of the conductive material such as a metal plate. As a result, an eddy current is generated in the conductive material itself due to the electromagnetic induction phenomenon, and this eddy current is converted into thermal energy, and the conductive material generates heat.
導電材としては、磁力により渦電流が発生し易い、銅、銀、アルミニウム、ステンレスなどの良導電体の金属を選択するのが好ましい。 As the conductive material, it is preferable to select a metal of a good conductor such as copper, silver, aluminum, and stainless steel, which easily generates eddy currents due to magnetic force.
永久磁石としては、例えば、ネオジウム系磁石、サマリウム系磁石などの表面3000ガウス以上の永久磁石を使用するのが好ましい。永久磁石の磁力の強さが強いほど導電材は高温に発熱する。永久磁石は導電材の周りを数100rpm以上で回転させる。必要発熱量や用途に応じて永久磁石の強さや極数、回転数は決定される。発熱温度調整はロータの回転数の調整により容易に行うことができる。 As the permanent magnet, for example, a permanent magnet having a surface of 3000 gauss or more such as a neodymium magnet or a samarium magnet is preferably used. The stronger the magnetic force of the permanent magnet, the more the conductive material generates heat. The permanent magnet rotates around the conductive material at several hundred rpm or more. The strength, the number of poles, and the number of rotations of the permanent magnet are determined according to the required calorific value and application. The exothermic temperature can be easily adjusted by adjusting the rotational speed of the rotor.
本発明のボイラーは、複数の永久磁石1aが任意の間隔をおいて固定された平盤状回転体1の上方かつ近傍(本実施例では25mm)に、発熱部2としてのアルミニウム製の円板が固定配置されている。 The boiler of the present invention is an aluminum disc as a
永久磁石1aを回転体1の円周に等間隔に配置する。磁石1aは、それぞれN極とS極とが交互に位置するように配置しても良いし、同極同士が隣接するように配置しても良い。配置する個数も任意である。回転体1は、モータ(図示せず)に連結された回転軸3により高速回転する。尚、本実施例においてモータの電源は商用電源としたが、太陽光、水力、風力等の自然界のエネルギーを用いて電源とすることが有益なことは言うまでもない。
さらに、本装置では、発熱部2に複数の放熱棒(放熱体)4を立設し、フード式の蓋体5を取付け、これによって生じる空間部を水や油等の熱媒体を貯留する貯留槽6とし、投入した熱媒体を炊き上げるようにしてもよい。尚、熱媒体流通管(管路)6は放熱棒4に近接して配置されるのが望ましい。また、図3に示すように、螺旋状に巻き上げて、下方から上方に向かって熱媒体を流通させ、園芸ハウス内等の所望の箇所に枝管を分岐させるものでも勿論よい。 Further, in the present apparatus, a plurality of heat dissipating rods (heat dissipating bodies) 4 are erected on the
本発明装置は、一般家庭における給湯における熱源として使用できることは無論のこと、農業分野での温室ハウス栽培における加温装置として実用性が高く極めて有用である。また、理論上、発熱部2は800℃以上の高温に加熱することが可能であり、図4に示すように、錐形の蓋体5で密閉された空間内で発熱部2に水を滴下し、水を蒸散させることで水素ガスと酸素ガスに分離できき、水素製造装置としての可能性も示唆できる。 Needless to say, the apparatus of the present invention can be used as a heat source for hot water supply in general households, and is highly useful as a heating apparatus for greenhouse house cultivation in the agricultural field.
