Description
この発明は、ＬＰＧやＬＮＧなどの液化ガスを気化するための気化器に係り、工業用や業務用などの気化効率に優れた気化器に関するものである。
The present invention relates to a vaporizer for vaporizing liquefied gas such as LPG and LNG, and relates to a vaporizer excellent in vaporization efficiency for industrial use and business use.
従来から、液化ガスの気化器として工業用や業務用などで利用する小型の気化器は知られている。この種の気化器は、コイル状に巻き回した管を円筒状の本体内に鋳込み、その中央部にヒータを挿通するための孔が設けられているものである。そして、ヒータによって本体を加熱し、管内をＬＰＧなどの液体を通過させることによって液化ＬＰＧが気化し、ＬＰＧガスを得ようとするものである。
DESCRIPTION OF RELATED ART Conventionally, the small sized vaporizer used for industrial use, business use, etc. as a vaporizer of liquefied gas is known. In this type of carburetor, a tube wound in a coil shape is cast in a cylindrical main body, and a hole for inserting a heater is provided at the center portion thereof. Then, the main body is heated by a heater, and a liquid such as LPG passes through the inside of the tube to vaporize liquefied LPG, thereby obtaining LPG gas.
ところで、上述した特許文献に記載された気化器は、液化ガスの流路である管を金属で鋳込むため、長期の稼働によって管が老朽化したり、管の内壁がなんらかの理由によって傷ついた場合にはこれを修理することは困難である。したがって、このような構成の気化器の場合には管が故障した場合には本体ごと交換する必要があった。しかも、管は金属によって鋳込まれているために、外部から目視によって点検することは事実上不可能であった。したがって、気化効率が急激に低下したり、長期の使用によって老化した場合には装置全体を交換する必要があった。
By the way, since the vaporizer described in the above-mentioned patent documents casts the pipe which is a flow path of liquefied gas with metal, when the pipe becomes old by long-term operation or the inner wall of the pipe is damaged for some reason It is difficult to fix this. Therefore, in the case of the carburetor of such a configuration, when the tube breaks down, it is necessary to replace the whole body. Moreover, since the tube is cast in metal, it is virtually impossible to visually inspect from the outside. Therefore, if the vaporization efficiency drops sharply or if the device is aged due to long-term use, it is necessary to replace the entire device.
本発明は、上記したように、従来の気化器のように装置に不具合が生じた場合でも全体を交換することなく、容易に装置を分解して点検をすることができ、不具合の箇所のみを交換することができる気化器を提供することを目的とするものである。
As described above, the present invention can easily disassemble and inspect the device without replacing the entire device even if the device has a defect as in the conventional vaporizer, and only the portion of the defect can be inspected. It is an object of the present invention to provide a vaporizer which can be replaced.
上述した目的を達成するために本発明では、垂直方向に厚みを有する円盤状の金属盤の底面、または上面に、液化ガス流路とする凹溝を設け、この凹溝の一部には垂直方向の貫通孔を設けて気化器ユニットとし、この気化器ユニットを複数段積層して凹溝を前記貫通孔によって連通させて１本の流路とした液化ガスの気化器を構成することとした。この構成では、液化ガスの気化のための流路を複数のほぼ同一の構成でユニット化しているので、気化能力などを気化器ユニットの積層数によって自在に設計することが可能である。また、ガス流路となる凹溝は外部から目視によって確認することができるので、点検などの際には確実な保守が可能となる。
In order to achieve the above-mentioned object, according to the present invention, a groove serving as a liquefied gas flow path is provided on the bottom or upper surface of a disk-shaped metal plate having a thickness in the vertical direction, and a part of the groove is vertical Through holes in the same direction are provided to form a vaporizer unit, and the vaporizer units are stacked in multiple stages, and the recessed grooves are communicated by the through holes to form a vaporizer for liquefied gas as one flow path. . In this configuration, since the flow paths for the vaporization of the liquefied gas are united with a plurality of substantially the same configurations, it is possible to freely design the vaporization capability and the like according to the number of stacked vaporizer units. In addition, since the concave groove serving as the gas flow path can be visually confirmed from the outside, reliable maintenance can be performed at the time of inspection or the like.
また、気化器ユニットを中央部に空間部を有するドーナツ状の円盤として、この空間部に液化ガスの気化のための熱源を設ける構成では、外部に熱源を求める構成と比較すると省スペースで全体構造を組み立てることができる。そして、気化器ユニットは、複数段を積層し、上下からベースプレートによって締め付けて一体とすることによって、組み立て分解を容易としている。
Further, in the configuration in which the vaporizer unit is a doughnut-shaped disk having a space at the center and the heat source for vaporization of the liquefied gas is provided in this space, the entire structure is saved in space as compared with the configuration in which the heat source is required outside Can be assembled. And a carburetor unit makes assembly disassembly easy by laminating | stacking multiple steps | stages and clamp | tightening from the upper and lower sides with a baseplate and integrating.
気化器ユニットの中央部に設けられる熱源として、複数本からなるヒータ発熱部を採用し、このヒータ発熱部をケーシングに収納して気化器ユニットの中央部に設ける構成では、気化器ユニットに対する熱の供給を均等とするものであり、さらにヒータ発熱部から発生する熱量をヒータ発熱部の本数によって自在に設計することができる。また、ヒータ発熱部を防爆のためのシールドケースで被覆することによって、安全対策を講じることも可能である。
In the configuration in which a plurality of heater heat generating parts are employed as a heat source provided at the central part of the vaporizer unit and the heater heat generating part is accommodated in the casing and provided at the central part of the vaporizer unit The supply is made uniform, and the amount of heat generated from the heater heating portion can be freely designed according to the number of heater heating portions. In addition, it is possible to take safety measures by covering the heater heat generating portion with a shield case for explosion proof.
ケーシングに最下段の気化器ユニットの位置に対応する位置に横方向からガス液入力口を設け、最上段の気化器ユニットに横方向に対してガス出力口を設けることによって、最上段の気化器ユニットを除いた他の気化器ユニットを同一の構造とすることが可能であり、装置の製造効率を向上することができる。
By providing the gas liquid input port in the lateral direction at a position corresponding to the position of the lowermost vaporizer unit in the casing, and providing the gas output port in the lateral direction in the uppermost vaporizer unit, the uppermost vaporizer It is possible to make other carburetor units other than a unit into the same structure, and to improve the manufacturing efficiency of the device.

以下、本発明の好ましい実施形態を添付した図面に従って説明する。図１は本発明の気化器の全体構成を示した縦断面図、図２はその横断面図であって、１は供給熱源として機能するヒータ発熱部、２はヒータ発熱部１の外周全体を被覆している絶縁物からなる防爆用のシールドケース、３はヒータ１を挿通し、ヒータ１の熱を周囲に放出するためのケーシングであり、これらの構成によって液化ガスに熱エネルギーを付与している。４はそれぞれが垂直方向に厚みを有し、ガス流路となる凹溝５が形成された円盤状で中央部にドーナツ状の空間部を有する気化器ユニットであり、この気化器ユニット４を複数層積層することによってガス流路を構成している。気化器ユニット４の詳細は後述する。６は液化ガス（液）のガス液入力口、７は液化ガス（気体）の出力口である。８・８は一対のベースプレートであって、中間部に複数の気化器ユニット４を挟んでシャフト９を挿通し、両端を締め付け固定することによって本実施形態の気化器を構成している。１０は凹溝５のガス流路からガス液あるいはガスの漏えいを防止するためのＯリングである。本実施形態では、ヒータ発熱部１を防爆のためにシールドケースに封入し、熱源から炎などが生じないようにしているが、防爆を考慮する必要がないのであれば、ヒータ発熱部１は露出させたままでケーシング３に挿通することもある。また、本実施形態ではヒータ発熱部１は装置中心１１の周囲に４本設置する構成としているが、必要な熱量、およびヒータ発熱部１の単位あたりの発生熱量に応じて本数を増減することは自由である。
Hereinafter, preferred embodiments of the present invention will be described with reference to the attached drawings. FIG. 1 is a longitudinal sectional view showing the entire configuration of the vaporizer according to the present invention, and FIG. 2 is a transverse sectional view thereof, wherein 1 is a heater heating portion functioning as a supply heat source and 2 is the entire outer periphery of the heater heating portion 1 An explosion-proof shield case made of insulating material, 3 is a casing for inserting the heater 1 and discharging the heat of the heater 1 to the surrounding, and applying thermal energy to the liquefied gas by these configurations There is. Each of the vaporizer units 4 has a thickness in the vertical direction, and is a disk-like unit having a concave groove 5 serving as a gas flow passage and having a donut-like space at the center. The gas flow path is configured by layering. Details of the vaporizer unit 4 will be described later. 6 is a gas liquid input port for liquefied gas (liquid), and 7 is an output port for liquefied gas (gas). 8 and 8 are a pair of base plates, and the shaft 9 is inserted through the plurality of carburetor units 4 in the middle part, and the both ends are tightened and fixed to configure the carburetor of this embodiment. The reference numeral 10 denotes an O-ring for preventing the leakage of the gas liquid or gas from the gas flow path of the recessed groove 5. In the present embodiment, the heater heating unit 1 is sealed in a shield case for explosion protection so that no flame or the like is generated from the heat source. However, the heater heating unit 1 is exposed if it is not necessary to consider explosion protection. It may be inserted into the casing 3 as it is. In the present embodiment, four heater heat generating parts 1 are provided around the center of the apparatus 11. However, the number of heater heat generating parts 1 may be increased or decreased according to the required heat quantity and the generated heat quantity per unit of heater heat generating part 1 It is free.
ここで、説明した気化器を利用して液化ガス（液）からガスを得るためには、先ずヒータ発熱部１に通電してヒータ発熱部１を発熱させる。そうすると、ケーシング３が加熱される結果、各気化器ユニット４が加熱昇温される。このようにして稼働状態にした実施形態の気化器に対して液化ガス（液）を入力口６から流入させると、液化ガス（液）は気化器ユニット４の凹溝５を通過するうちに昇温し、ガス化し、最上段の気化器ユニットに形成されたガス出力口７から気化状態でガスが流出する。
Here, in order to obtain the gas from the liquefied gas (liquid) using the vaporizer described above, first, the heater heating unit 1 is energized to cause the heater heating unit 1 to generate heat. Then, as a result of the casing 3 being heated, each vaporizer unit 4 is heated and heated. When liquefied gas (liquid) is made to flow from the input port 6 to the vaporizer of the embodiment thus brought into operation, the liquefied gas (liquid) rises while passing through the recessed groove 5 of the vaporizer unit 4 The gas is warmed, gasified, and gas flows out in a vaporized state from the gas output port 7 formed in the uppermost vaporizer unit.
次に、各気化器ユニット４の構成について説明する。図３は気化器ユニット４の底面図、図４は縦断面図である。ここで、気化器ユニット４は、ダイキャストで鋳込まれたアルミニウムの円盤本体１２の底側１３を切削して凹溝５を形成している。なお、素材についてはアルミニウムが工作、コストの点から有利であるが、熱伝導率が優れ、かつコストの負担が少ない素材であれば、例えば銅を用いることも本発明に含まれる。凹溝５の形状は、円盤本体１２の円形に沿ってＣ字形状としているが、Ｃ字形状を基本として、流体抵抗が必要な場合には波形に蛇行させたり、凹溝５の幅を広い狭いを繰り返すなど、適宜選択することができる。１３は上下方向に対する貫通孔である。そして、複数の気化器ユニット４～４を積層することによって、各凹溝５～５が直接重なり合う気化器ユニット４の垂直孔１３によって連通し、その結果として複数の積層する気化器ユニット４～４全体の凹溝５～５が１本のガス流路となる。なお、１４は積層した気化器ユニット４～４を密に締結するためのシャフト挿通孔である。シャフト挿通孔１４は、本実施形態では８個設けているが、確実に気化器ユニット４を一体とすることができるのであれば、その個数は問わない。１５は、図１に示した液化ガス（気体）の出力口であり、複数の気化器ユニット４～４のうち、１個だけに設けられる構成である。なお、気化器ユニット４は、その積層の際には各気化器ユニット４の底面にグリースを塗布し、気化器ユニット４・４間の熱伝達効率を良好にし、蒸発効率を向上させることがある。図５は、気化器ユニット４を底面側から見た状態を示す斜視図である。
Next, the configuration of each vaporizer unit 4 will be described. FIG. 3 is a bottom view of the vaporizer unit 4, and FIG. 4 is a longitudinal sectional view. Here, the carburetor unit 4 forms the recessed groove 5 by cutting the bottom side 13 of the aluminum disk body 12 cast in by die casting. In addition, although aluminum is advantageous from the point of work and cost about a raw material, if it is a raw material which is excellent in thermal conductivity and has a small burden of cost, using copper, for example is also included in this invention. The shape of the recessed groove 5 is C-shaped along the circular shape of the disk main body 12, but based on the C-shaped, if the fluid resistance is required, the waved meanders or the width of the recessed groove 5 is increased. Repeated narrowing can be selected as appropriate. Reference numeral 13 denotes a through hole in the vertical direction. Then, by laminating the plurality of vaporizer units 4 to 4, the respective recessed grooves 5 to 5 communicate with the vertical holes 13 of the directly overlapping vaporizer unit 4, and as a result, a plurality of laminated vaporizer units 4 to 4 The entire recessed grooves 5 to 5 form one gas flow path. Reference numeral 14 denotes a shaft insertion hole for tightly fastening the stacked vaporizer units 4 to 4. Although eight shaft insertion holes 14 are provided in the present embodiment, the number of the shaft insertion holes 14 is not limited as long as the carburetor unit 4 can be reliably integrated. Reference numeral 15 denotes an output port of the liquefied gas (gas) shown in FIG. 1, which is provided on only one of the plurality of vaporizer units 4 to 4. In addition, the vaporizer unit 4 applies a grease on the bottom of each vaporizer unit 4 in the case of the lamination | stacking, the heat transfer efficiency between vaporizer units 4 * 4 may be made favorable, and evaporation efficiency may be improved. . FIG. 5 is a perspective view showing the carburetor unit 4 viewed from the bottom side.
ところで、図示した状態から明らかなように、気化器ユニット４の構成は、最上段の気化器ユニットについてはガス出力口７を設ける必要から、かつガス出力口７の径を十分に考慮することから、その他の気化器ユニットより厚みが大きい。ただし、この点についてはガス液入力口６をケーシング３に設けたように、別途ガス出力口７をケーシング３に形成することによって他の気化器ユニット４と同じ構成とすることも可能である。
By the way, as apparent from the illustrated state, the configuration of the vaporizer unit 4 needs to provide the gas output port 7 for the uppermost vaporizer unit, and because the diameter of the gas output port 7 is sufficiently considered. , Thicker than other vaporizer units. However, in this respect, as in the case where the gas liquid input port 6 is provided in the casing 3, the gas output port 7 may be separately formed in the casing 3 to have the same configuration as the other vaporizer units 4.
図６、図７は本実施形態の気化器の第２例であって、ヒータ発熱部１は防爆を施さずに露出した構成を採用している。そして、気化器ユニット４の積層数は第１例の１１段よりも多い１４段としている。気化器ユニット４の積層数については、特に限定するものではなく、熱源から発生する熱エネルギーの総量や、装置に求める能力に応じて増減することが可能である。また、各気化器ユニット４～４の積層形態については、第１例では垂直孔１３の位置を４５度ずつずらせながら積層しているが、第２例では垂直孔１３を１８０度回転位置として、いわゆる千鳥状としている。また、凹溝５については、第１例では溝が切削されていない場所、すなわちＣ字状の切れ目の長さを長くしたが、図７の第２例のようにほぼ環状に切削して、一部のみを切削しない形態にすることもある。この場合には全体のガス流路を長くすることが可能になるので、気化効率をより向上させることができる。このような構成に替えて、工作時にはまず環状に凹溝５を切削し、その後一部の箇所を別途金属などで閉塞することでガス流路を得ることも可能である。
FIGS. 6 and 7 show a second example of the vaporizer according to the present embodiment, in which the heater heating portion 1 is exposed without being subjected to explosion protection. And the number of laminated layers of the vaporizer unit 4 is 14 stages which is larger than the 11 stages of the first example. The number of laminated layers of the vaporizer unit 4 is not particularly limited, and can be increased or decreased according to the total amount of thermal energy generated from the heat source and the capability required of the device. Moreover, about the lamination | stacking form of each vaporizer unit 4-4, although laminating | stacking shifting the position of the perpendicular hole 13 every 45 degree | times in a 1st example, the perpendicular hole 13 is made into a 180 degree rotation position in a 2nd example It has a so-called zigzag shape. In the first example, the groove 5 is not cut, i.e., the length of the C-shaped cut is increased. However, as in the second example of FIG. There is also a form that does not cut only a part. In this case, it is possible to make the entire gas flow path longer, so that the vaporization efficiency can be further improved. Instead of such a configuration, it is also possible to obtain the gas flow path by cutting the groove 5 annularly at the time of machining and then partially closing the part with metal or the like.
上記のように説明した実施形態では、気化器ユニット４を円盤状としたが、流路抵抗などを厳格に考慮する必要がないのであれば、気化器ユニット４の平面形状を円形ではなく、多角形とすることを排除するものではない。また、熱源については電力供給によるヒータ加熱を一例として説明したが、ヒータ発熱部１に替えて水や油を昇温して熱媒としたり、スチームを供給することも可能である。必要なことは、中央部に設けられた熱源から気化器ユニット４の凹溝５に対して効率的に熱エネルギーを与えることであり、これを充足するのであれば熱源の構成は特に限定するものではない。さらに、熱源は本実施形態では中央部に設けられているが、気化器ユニット４の外周から熱エネルギーを付与する構成であってもよい。このように、気化器ユニット４の外周に熱源を設ける構成であれば、気化器ユニット４の全体形状はドーナツ状ではなく、円盤状であっても採用することが可能である。
In the embodiment described above, the carburetor unit 4 has a disk shape, but if it is not necessary to strictly consider the flow path resistance etc., the planar shape of the carburetor unit 4 is not circular, but many It does not exclude that making it a square. Further, as the heat source, the heater heating by the power supply has been described as an example, but it is also possible to change the heater heating portion 1 and raise the temperature of water or oil to use as a heat medium or supply steam. What is required is that heat energy be efficiently applied to the recessed groove 5 of the vaporizer unit 4 from the heat source provided at the central portion, and the configuration of the heat source is particularly limited if the heat energy is satisfied. is not. Furthermore, although the heat source is provided at the central portion in the present embodiment, the heat energy may be applied from the outer periphery of the vaporizer unit 4. As described above, as long as the heat source is provided on the outer periphery of the vaporizer unit 4, the overall shape of the vaporizer unit 4 can be adopted even if it is not a doughnut shape but a disk shape.
また、本実施形態では気化器ユニット４に設けられる凹溝５は、気化器ユニット４の底面に形成したが、逆に上面に凹溝を形成した場合であっても達成することができる目的や機能になんら変わるところはないことはもちろんである。さらに、本発明の基本的な構造では、気化器ユニットの径を大きくしたり、積層数を増やすことによって大型の気化器に適用することができるのはいうまでもない。
Moreover, although the recessed groove 5 provided in the vaporizer unit 4 is formed in the bottom surface of the vaporizer unit 4 in the present embodiment, the purpose that can be achieved even when the recessed groove is formed in the upper surface Of course there is no change in functionality. Furthermore, it goes without saying that the basic structure of the present invention can be applied to a large vaporizer by increasing the diameter of the vaporizer unit or increasing the number of stacked layers.
