Description

【0001】
【発明の属する技術分野】
本発明は、車両および小型船舶用エンジンの逆火防止に使用されるフレームアレスタ用メタルハニカムに関する。
【0002】
【従来の技術】
フレームアレスタは可燃性、爆発性のガス体を輸送するパイプまたはこれらのガス体が漏出する可能性のある危険物貯蔵タンク室の通気口、換気口等で逆火(火炎伝播)を防止することを目的とした安全装置である。フレームアレスタの原理は火炎を細分化して消滅させることにあり、燃焼室から逆流してきた混合気体または火炎を多孔体からなる消炎素子でその圧力を低下させることにより混合気体の逆流を阻止し、さらに熱を吸収させて混合気体を着火温度以下までに下げることにより燃焼の伝播を阻止するものである。消炎素子としては、金網、金属多孔板、石綿網、セラミックハニカム、メタルハニカム、燒結金属等の無機質多孔体が使用されている。
【0003】
車両および小型船舶用のフレームアレスタは、小型軽量であること、混合ガスの通過圧力損失が小さいこと等が要求される。これらの要求から、車両用および小型船舶用のフレームアレスタの消炎素子としてはメタルハニカムが用いられることが多い。
【0004】
図1は従来技術になる車両および小型船舶用のフレームアレスタ用メタルハニカムの一例である。ハニカム体1は、三角形状に波付された波板2と、平板3とを重ね合せ、これらを中心から外側に向けて螺旋状に多重に巻回して形成されている。波板2、および平板3は17重量%のCrおよび7重量%Niを含むオーステナイト系ステンレス(Fe−Cr−Ni系)からなり、板厚は50μmである。ハニカム体1は全体として円柱形状をもち、その最外周6は平板3を多重回(例えば5回)巻回することにより固定されている。ハニカム体の巻芯部空間は、円柱形のオーステナイト系ステンレスからなる巻芯金4で封止されている。さらに、ハニカム体の最外周から直径方向に巻芯金を貫通する貫通孔5’を設け、ピン5によってハニカム体1の波板2、平板3および巻芯金4を一体的に固定してハニカムのズレ止めとしている。
【0005】
以上のようにして形成されるフレームアレスタ用メタルハニカムは、全体の断面積の割には有効断面積が小さく圧力損失が大きい、直径方向にピン5を通してハニカムのズレを防止するために、波板2や平板3は50μmという厚さが必要であり、かつ加工工数がかかる。耐食性を維持するためにオーステナイト系ステンレス鋼という高価な材料を必要とする。そして結果的に製品重量が大きいといった諸々の問題を抱えている。
【0006】
【発明が解決しようとする課題】
本発明の目的は、従来技術と同様の耐食性を維持し、有効断面積が大きく圧力損失の少ない、かつ製造コストが低減できる、車両および小型船舶用のフレームアレスタ用メタルハニカムを提供することである。
【0007】
【課題を解決するための手段】
本発明のフレームアレスタ用メタルハニカムは、幅方向に所定の傾斜角度で波付けされた少なくとも一枚の金属製の波板が、波付けされた波形の凸部及び凹部が延伸方向に交差するように巻回され軸方向に延びる多数の通孔をもつハニカム体と、巻回された波板の当接部を接合するろう材と、ハニカム体の巻芯部空間に装着された金属製の球体とを有することを特徴とする。
【0008】
本発明のフレームアレスタ用メタルハニカムでは、より安価な金属材料を使用して、ろう材を用いて波板を接合することにより、耐食性を維持しながら、材料使用量と加工工数とを低減することができる。さらに、巻芯部空間を金属製の球体で封止することによって、容易に巻芯部空間を閉止し巻芯部空間からの火炎の伝播を阻止することができる。
【0009】
【発明の実施の形態】
本発明のフレームアレスタ用メタルハニカムは、少なくとも一枚の金属製の波板が巻回された軸方向に多数の通孔をもつハニカム体と、巻回された波板の当接部を接合するろう材と、ハニカム体の巻芯部空間に装着された金属製の球体とからなる。
【0010】
ハニカム体は、少なくとも一枚の波板を螺旋状に巻回して形成される。ハニカム体の形状は、通孔密度が大きく気体の圧力損失の小さいものであれば特に制限はない。例えば、ある角度をもって波付された金属板2枚を凸部および凹部が延びる方向に交差するように巻回することにより隣接する波板の凸部と凹部によって得られる間隙が気体が通過できる通孔となるハニカム体を例示することができる。このようにして得られた通孔は網目状に形成されるので、通孔を通過する気体の接触面積を増大することができ、フレームアレスタ用メタルハニカムとして優れた効果を発揮する。また、このように波板のみからなるハニカム体は、材料使用量を節減できるのでフレームアレスタ用メタルハニカムのコストを低減することができる。
【0011】
本発明になるハニカム体は、フェライト系ステンレスの耐熱鋼やオーステナイト系ステンレス等、高温耐食性および耐高温酸化性等に優れた金属で形成されることができる。しかし、材料費の節約を目的とした場合には、より廉価なフェライト系ステンレスを用いることが望ましい。また、材料の板厚は40〜100μmが適当である。40μm未満ではハニカム体の強度が不十分であり、100μmを越えると本発明のコストダウンの目的にそぐわない。
【0012】
波板の波形形状は特に制限はなく、正弦波形状、三角形状、半円形状、台形状等を採用することができる。2枚の波板を螺旋状に巻回してハニカム体を構成する場合には、図5に示す傾斜角度を付けて波付することが好ましい。
【0013】
ろう材は、ニッケル(Ni)、アルミニウム(Al)、クロム(Cr)等のいずれか一つまたは複数を主成分とすることができる。しかし、ハニカム体の金属材料としてフェライト系ステンレスを使用した場合には、耐食性を維持するためにNiを主成分としたろう材を使用することが好ましい。ろう材には通常バインダ(結合材)が混入される。ろう材は、スラリ状のろう材をハニカム体全体に塗布した後、ハニカム体を加熱することにより水分を蒸発させて固着させる。その後真空熱処理によってろう材を溶融させ、当接している波板同士が接合される。
【0014】
さらに、ハニカム体の表面はNiを含むろう材で全面的に被覆されるためオーステナイト系ステンレスと同等の耐食性を付与することができる。このため、ろう材には70〜94重量%のNiを含有しているものが望ましい。
【0015】
ハニカム体の巻芯部空間は金属製の球体を嵌入して封止する。気体の圧力損失を小さくするためには巻芯部空間は出来だけ小さい方が好ましい。しかし、従来技術ではこの巻芯部空間を円柱状の金属棒で封止するために、巻芯部空間が余り小さいと封止作業に支障をきたす。本発明では円柱状の金属棒の代りに金属製の球体を採用することで巻芯部空間が小さくても容易に封止作業を行うことができる。また、巻芯部空間が小さくできるので、気体を通過させる有効断面積が増加して圧力損失を低減することができる。さらに、巻芯部を封止するために必要な使用材料が少なくてすみ製品のコスト低減と軽量化を図ることができる。
【0016】
金属製の球体は、フェライト系ステンレスの耐熱鋼やオーステナイト系ステンレス等、高温耐食性および耐高温酸化性等に優れた金属からなることができる。しかし、材料費の節約を目的とした場合にはより廉価なフェライト系ステンレスを用いることが望ましい。この金属製の球体は、巻芯部空間の直径よりも若干大きい直径をもち、巻芯部空間へ嵌入することにより機械的に固定される程度の大きさが望ましい。
【0017】
ハニカム体の製造方法には特に制限はなく、汎用の方法を採用することができる。ただし、巻芯部への金属製の球体の装着は、ろう材による接合の前に実施し、ろう材による波板の接合と同時にハニカム体に接合されるように行うことが望ましい。
【0018】
以上のように本発明になるフレームアレスタ用メタルハニカムでは、従来技術に比較して材料使用量を削減することができる。また、フレームアレスタ用メタルハニカムの製造に要する時間を大幅に短縮することができる。
【0019】
【実施例】
本実施例のフレームアレスタ用メタルハニカムを図2に示す。また、図2のA−Aで切断した片側の斜視図を図3に示す。このメタルハニカムは、波板2を螺旋状に巻回してなるハニカム体1と、ハニカム体1の最外周に1〜2回巻回された平板3と、図示されていないろう材と、巻芯部空間に装着された金属製の球体7とからなる。
【0020】
板厚50μm、板幅13mmのフェライト系ステンレス板にヘリカルギアを用いて図4および図5に示すように、幅方向より10度の傾斜角度で波付をして、波板10を得た。なお図4は波板10の一部を示した斜視図であり、図5は水平におかれた波板10を上から見た平面図の一部である。このようにして得られた波板10と、同形状の波板20を波板10に裏返して重ね、螺旋状に巻回してハニカム体1を得た。波板10および波板20は、図6に示すように、断面が交互に凸部と凹部とからなる波形状であって、巻回されることにより通孔30を形成する。波のピッチは2.4mmで、波の高さは1.3mmであった。また、巻回して得られたハニカム体1は、直径68mm、幅13mmで約31個/cm2の通孔30が形成されている。
【0021】
ハニカム体1の巻芯部空間8の直径は、約4mmであった。この巻芯部空間8にフェライト系ステンレスからなる直径4mmの球体7を嵌入して巻き芯部空間8を封止した。
【0022】
つぎにろう材塗布装置により、巻芯部空間8に球体7を嵌入したハニカム体1にNiを主成分としたスラリ状のろう材を塗布した。スラリ状のろう材は、ハニカム体全体に塗布し、真空度0.5×10-4Paで1180℃、20分間の真空熱処理を施した。これにより、波板10と波板20とはろう材で接合され、また、巻芯部では最内周の波板と嵌入された球体7とが接合された。フェライト系ステンレスからなるハニカム体1の表面は、全体がNiを含むろう材で被覆されるためにオーステナイト系ステンレスと同等の耐食性を付与することができる。ろう材の被覆層の厚さは約2μmで分析の結果6.7重量%のNiを含有していることが確認できた。この値はSUS304に代表されるオーステナイト系ステンレスの7重量%Niにほぼ近い値であり、オーステナイト系ステンレスと同様の耐食性が期待できる
次に上記で得られた本実施例のフレームアレスタ用メタルハニカムと従来技術になるフレームアレスタ用メタルハニカムについて、気体の圧力損失、重量、加工工数などを比較した。
【0023】
従来技術になるフレームアレスタ用メタルハニカムの各値を1とした場合に、本実施例のフレームアレスタ用メタルハニカムでは、気体の圧力損失が0.8、重量は0.5、加工工数は0.5となった。
【0024】
【発明の効果】
本発明のフレームアレスタ用メタルハニカムは、少なくとも一枚の金属製の波板が巻回された軸方向に多数の通孔をもつハニカム体と、巻回された波板の当接部を接合するろう材と、ハニカム体の巻芯部空間に装着された金属製の球体とからなる。巻芯部空間は、金属製の球体で封止されるために封止作業性を向上することができ、さらに巻芯部空間からの火炎の伝播を阻止することができる。また、本発明によれば、安価な金属材料と、ろう材によるハニカムのズレ防止を採用できるので、従来技術と同様の耐食性を有しながら材料使用量を節減した軽量でかつ廉価なフレームアレスタ用メタルハニカムを提供することができる。

BACKGROUND OF THE INVENTION
The present invention relates to a metal honeycomb for a frame arrester used for preventing backfire of a vehicle and a small marine engine.
[0002]
[Prior art]
Flame arresters should prevent backfire (flame propagation) in pipes that transport flammable or explosive gas bodies or vents, vents, etc. in dangerous substance storage tank rooms where these gas bodies may leak. It is a safety device for the purpose. The principle of the flame arrester is to subdivide and extinguish the flame. By reducing the pressure of the mixed gas or flame that has flowed back from the combustion chamber with a flame extinguishing element made of porous material, the back flow of the mixed gas is prevented, The propagation of combustion is prevented by absorbing the heat and lowering the mixed gas to below the ignition temperature. As the flame extinguishing element, an inorganic porous body such as a metal net, a metal porous plate, an asbestos net, a ceramic honeycomb, a metal honeycomb, and a sintered metal is used.
[0003]
Frame arresters for vehicles and small ships are required to be small and light, and to have a low pressure loss of the mixed gas. In view of these requirements, a metal honeycomb is often used as a flame extinguishing element for a frame arrester for vehicles and small ships.
[0004]
FIG. 1 shows an example of a conventional metal honeycomb for a frame arrester for vehicles and small ships. The honeycomb body 1 is formed by overlapping a corrugated sheet 2 corrugated in a triangular shape and a flat plate 3 and winding them in a spiral manner from the center to the outside. The corrugated plate 2 and the flat plate 3 are made of austenitic stainless steel (Fe—Cr—Ni based) containing 17 wt% Cr and 7 wt% Ni, and the plate thickness is 50 μm. The honeycomb body 1 has a cylindrical shape as a whole, and the outermost periphery 6 is fixed by winding the flat plate 3 multiple times (for example, 5 times). The core space of the honeycomb body is sealed with a core metal 4 made of a cylindrical austenitic stainless steel. Further, a through hole 5 ′ that penetrates the cored bar in the diameter direction from the outermost periphery of the honeycomb body is provided, and the corrugated plate 2, the flat plate 3, and the cored bar 4 of the honeycomb body 1 are fixed integrally with the pin 5 by the honeycomb. I'm trying to stop misalignment.
[0005]
The metal honeycomb for a frame arrester formed as described above has a corrugated plate in order to prevent the honeycomb from being displaced through the pins 5 in the diametrical direction with a small effective sectional area and large pressure loss for the entire sectional area. 2 and the flat plate 3 are required to have a thickness of 50 μm and require a large number of processing steps. In order to maintain the corrosion resistance, an expensive material called austenitic stainless steel is required. As a result, it has various problems such as large product weight.
[0006]
[Problems to be solved by the invention]
An object of the present invention is to provide a metal honeycomb for a frame arrester for vehicles and small boats that maintains the same corrosion resistance as that of the prior art, has a large effective cross-sectional area, has a small pressure loss, and can reduce manufacturing costs. .
[0007]
[Means for Solving the Problems]
The metal honeycomb for a frame arrester according to the present invention has at least one corrugated metal sheet corrugated in the width direction at a predetermined inclination angle so that the corrugated convex and concave portions intersect with the stretching direction. A honeycomb body having a large number of through-holes wound in the axial direction, a brazing material for joining the contact portions of the wound corrugated sheet, and a metal body mounted in the core space of the honeycomb body And a sphere.
[0008]
In the metal honeycomb for a frame arrester of the present invention, by using a cheaper metal material and joining the corrugated sheet using a brazing material, the amount of material used and the number of processing steps can be reduced while maintaining corrosion resistance. Can do. Furthermore, by sealing the core part space with a metal sphere, it is possible to easily close the core part space and prevent the propagation of flame from the core part space.
[0009]
DETAILED DESCRIPTION OF THE INVENTION
The metal honeycomb for a frame arrester of the present invention joins a honeycomb body having a large number of through holes in the axial direction around which at least one corrugated metal plate is wound, and a contact portion of the wound corrugated plate. It consists of a brazing material and a metal sphere mounted in the core space of the honeycomb body.
[0010]
The honeycomb body is formed by spirally winding at least one corrugated sheet. The shape of the honeycomb body is not particularly limited as long as the hole density is large and the pressure loss of the gas is small. For example, by winding two metal plates corrugated at a certain angle so as to intersect the direction in which the convex portions and the concave portions extend, the gap obtained by the convex portions and concave portions of the adjacent corrugated plates can pass through the gas. A honeycomb body to be a hole can be exemplified. Since the through holes obtained in this way are formed in a mesh shape, the contact area of the gas passing through the through holes can be increased, and an excellent effect as a metal honeycomb for a frame arrester is exhibited. In addition, since the honeycomb body made only of corrugated sheets can reduce the amount of material used, the cost of the metal honeycomb for the frame arrester can be reduced.
[0011]
The honeycomb body according to the present invention can be formed of a metal excellent in high temperature corrosion resistance, high temperature oxidation resistance, and the like, such as heat resistant steel of ferritic stainless steel and austenitic stainless steel. However, for the purpose of saving material costs, it is desirable to use a less expensive ferritic stainless steel. The plate thickness of the material is suitably 40-100 μm. When the thickness is less than 40 μm, the strength of the honeycomb body is insufficient, and when the thickness exceeds 100 μm, it does not meet the purpose of cost reduction of the present invention.
[0012]
The corrugated shape of the corrugated plate is not particularly limited, and a sinusoidal shape, a triangular shape, a semicircular shape, a trapezoidal shape, or the like can be adopted. When a honeycomb body is formed by spirally winding two corrugated sheets, it is preferable to corrugate with an inclination angle shown in FIG.
[0013]
The brazing material can contain any one or more of nickel (Ni), aluminum (Al), chromium (Cr) and the like as a main component. However, when ferritic stainless steel is used as the metal material of the honeycomb body, it is preferable to use a brazing material containing Ni as a main component in order to maintain corrosion resistance. Usually, a binder (binding material) is mixed in the brazing material. The brazing material is fixed by evaporating moisture by applying a slurry brazing material to the entire honeycomb body and then heating the honeycomb body. Thereafter, the brazing material is melted by vacuum heat treatment, and the corrugated plates that are in contact with each other are joined.
[0014]
Furthermore, since the surface of the honeycomb body is entirely covered with a brazing material containing Ni, corrosion resistance equivalent to that of austenitic stainless steel can be imparted. For this reason, it is desirable that the brazing material contains 70 to 94% by weight of Ni.
[0015]
The core space of the honeycomb body is sealed by inserting a metal sphere. In order to reduce the pressure loss of gas, it is preferable that the core space is as small as possible. However, in the prior art, since the core space is sealed with a cylindrical metal rod, if the core space is too small, the sealing operation is hindered. In the present invention, by using a metal sphere instead of the columnar metal rod, the sealing operation can be easily performed even if the core space is small. Moreover, since the core part space can be reduced, the effective cross-sectional area through which the gas passes can be increased and the pressure loss can be reduced. Furthermore, less material is required to seal the core, and the cost and weight of the product can be reduced.
[0016]
The metal sphere can be made of a metal excellent in high temperature corrosion resistance and high temperature oxidation resistance, such as a heat resistant steel of ferritic stainless steel or austenitic stainless steel. However, it is desirable to use a cheaper ferritic stainless steel for the purpose of saving material costs. The metal sphere has a diameter slightly larger than the diameter of the core space and is preferably large enough to be mechanically fixed by being fitted into the core space.
[0017]
There is no restriction | limiting in particular in the manufacturing method of a honeycomb body, A general purpose method is employable. However, it is desirable that the metal spheres be attached to the winding core part before joining with the brazing material and so as to be joined to the honeycomb body simultaneously with the joining of the corrugated sheet with the brazing material.
[0018]
As described above, in the metal honeycomb for a frame arrester according to the present invention, the amount of material used can be reduced as compared with the prior art. Further, the time required for manufacturing the metal honeycomb for the frame arrester can be greatly shortened.
[0019]
【Example】
A metal honeycomb for a frame arrester of this example is shown in FIG. Moreover, the perspective view of the one side cut | disconnected by AA of FIG. 2 is shown in FIG. This metal honeycomb includes a honeycomb body 1 formed by spirally winding a corrugated sheet 2, a flat plate 3 wound around the outermost periphery of the honeycomb body 1, a brazing material (not shown), and a winding core. It consists of a metal sphere 7 mounted in the partial space.
[0020]
As shown in FIGS. 4 and 5, a corrugated sheet 10 was obtained by corrugating a ferrite stainless steel sheet having a thickness of 50 μm and a width of 13 mm using a helical gear at an inclination angle of 10 degrees from the width direction. FIG. 4 is a perspective view showing a part of the corrugated sheet 10, and FIG. 5 is a part of a plan view of the corrugated sheet 10 placed horizontally. The corrugated sheet 10 obtained in this way and the corrugated sheet 20 having the same shape are turned upside down on the corrugated sheet 10 and wound spirally to obtain the honeycomb body 1. As shown in FIG. 6, the corrugated sheet 10 and the corrugated sheet 20 have a corrugated shape in which a cross section is alternately composed of convex portions and concave portions, and the through holes 30 are formed by winding. The wave pitch was 2.4 mm and the wave height was 1.3 mm. Further, the honeycomb body 1 obtained by winding has a diameter of 68 mm, a width of 13 mm, and about 31 holes / cm 2 of through-holes 30 are formed.
[0021]
The diameter of the core part space 8 of the honeycomb body 1 was about 4 mm. A sphere 7 having a diameter of 4 mm made of ferritic stainless steel was inserted into the core space 8 to seal the core space 8.
[0022]
Next, a slurry brazing material containing Ni as a main component was applied to the honeycomb body 1 in which the spheres 7 were fitted in the core space 8 with a brazing material coating apparatus. The slurry-like brazing material was applied to the entire honeycomb body and subjected to vacuum heat treatment at 1180 ° C. for 20 minutes at a vacuum degree of 0.5 × 10 −4 Pa. Thereby, the corrugated sheet 10 and the corrugated sheet 20 were joined by the brazing material, and the innermost peripheral corrugated sheet and the inserted spherical body 7 were joined at the core. Since the entire surface of the honeycomb body 1 made of ferritic stainless steel is coated with a brazing material containing Ni, corrosion resistance equivalent to that of austenitic stainless steel can be imparted. The thickness of the coating layer of the brazing material was about 2 μm, and as a result of analysis, it was confirmed that it contained 6.7% by weight of Ni. This value is almost close to 7 wt% Ni of austenitic stainless steel represented by SUS304, and the same corrosion resistance as that of austenitic stainless steel can be expected. We compared the pressure loss, weight, processing man-hours, etc. of the metal honeycomb for flame arresters, which is a conventional technology.
[0023]
When each value of the frame arrester metal honeycomb according to the prior art is set to 1, in the frame arrester metal honeycomb of this embodiment, the gas pressure loss is 0.8, the weight is 0.5, and the processing man-hour is 0. It became 5.
[0024]
【The invention's effect】
The metal honeycomb for a frame arrester of the present invention joins a honeycomb body having a large number of through holes in the axial direction around which at least one corrugated metal plate is wound, and a contact portion of the wound corrugated plate. It consists of a brazing material and a metal sphere mounted in the core space of the honeycomb body. Since the core part space is sealed with a metal sphere, the sealing workability can be improved, and further, the propagation of flame from the core part space can be prevented. In addition, according to the present invention, since it is possible to employ an inexpensive metal material and prevention of honeycomb displacement by brazing material, it is used for a light and inexpensive frame arrester that has the same corrosion resistance as the prior art but reduces the amount of material used. A metal honeycomb can be provided.
