In particular, technical issues such as pressure loss caused by interposing a spacer and accumulation of foreign matters on the spacer are important items. It has become. In addition to this, when stacking heat exchangers in multiple stages, it has been required that the heat exchanger can be constructed accurately and easily even if it is not an expert. Furthermore, it is required that the spacer can be easily manufactured.

以下に、図面を参照しつつ本発明の好ましい実施の形態を示す。
図１は、縦横複数列に並べたセラミックフィルタ群を多段に積層した熱交換器の正面図、図２は本発明のスペーサを並べた状態を示す平面図、図３は図１の要部の斜視図である。図において、１１は軸方向に多数の連通孔が形成されている四角柱状のセラミックフィルタ、１２はこのセラミックフィルタ１１を縦横複数列（図示のものでは１６×１６）に並べたセラミックフィルタ群であり、図示のものではセラミックフィルタ群１２を４段積層してある。なお、１３は熱交換器のケースである。 Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings.
1 is a front view of a heat exchanger in which ceramic filter groups arranged in multiple rows and columns are stacked in multiple stages, FIG. 2 is a plan view showing a state in which spacers of the present invention are arranged, and FIG. It is a perspective view. In the figure, 11 is a quadrangular columnar ceramic filter in which a large number of communicating holes are formed in the axial direction, and 12 is a group of ceramic filters in which the ceramic filters 11 are arranged in a plurality of rows (16 × 16 in the figure). In the illustrated example, four ceramic filter groups 12 are laminated. Reference numeral 13 denotes a heat exchanger case.

熱交換器の各段間には、スペーサ１が挿入されている。このスペーサ１は、１個のセラミックフィルタ１１の外径と同一形状を有する四角状の枠体１ａを縦方向および／または横方向に整列させて複数個連結した構造となっている。
実施例のものでは、図４に示すように、８個の枠体１ａを、１列に整列させて直線状に連結したものとなっている。その他、枠体１ａを縦横複数列に整列させて四角状に連結したものとすることもできる。この連結する枠体１ａの個数や、形状については、重量等の関係や設置スペース等から任意に選択することができるものである。 Spacers 1 are inserted between the stages of the heat exchanger. The spacer 1 has a structure in which a plurality of square frames 1a having the same shape as the outer diameter of one ceramic filter 11 are aligned in the vertical direction and / or the horizontal direction and connected.
In the embodiment, as shown in FIG. 4, eight frame bodies 1a are aligned in a line and connected in a straight line. In addition, the frames 1a may be arranged in a plurality of rows and columns and connected in a square shape. The number and shape of the frames 1a to be connected can be arbitrarily selected from the relationship such as weight and the installation space.

このようなスペーサ１は、例えばＳＵＳ３１０ＳやＳＵＳ３０４等のステンレス鋼のような帯状の耐熱鋼材や、コージライトやムライト等のセラミックで形成することができる。実施例では、帯状の耐熱鋼材で１個のセラミックフィルタ１１の外径と同一形状を有する四角状の枠体１ａを形成し、これを１列に整列させて直線状に溶接した構造となっている。この他に、帯状の耐熱鋼材を梯子状に組み合わせて溶接し、直線状のスペーサ１とすることもできる。また、セラミックで形成する場合は、前記枠体１ａが１列に整列されて直線状に連結したものや、縦横複数列に整列されて四角状に連結したものを一体的に成形することができる。   Such a spacer 1 can be formed of, for example, a belt-shaped heat-resistant steel material such as stainless steel such as SUS310S or SUS304, or ceramic such as cordierite or mullite. In the embodiment, a rectangular frame body 1a having the same shape as the outer diameter of one ceramic filter 11 is formed of a belt-like heat-resistant steel material, and this is aligned in one row and welded linearly. Yes. In addition, the linear spacer 1 can be formed by combining and welding band-shaped heat-resistant steel materials in a ladder shape. Further, in the case of being formed of ceramic, the frame 1a can be integrally formed by aligning the frames 1a in a single line and connecting them in a straight line, or by aligning the frames 1a in a plurality of vertical and horizontal lines and connecting them in a square shape. .

また、図４に示されるように、枠体１ａの四隅には、角部の内側を斜めに横切って連結する補強部材２が取り付けてある。これにより、枠体１ａの強度を大幅に向上させることができ、またセラミックフィルタ１１を載置した場合にも安定性が増し、かつ重量にも十分に耐えられるという効果を発揮する。この補強部材２は、枠体１ａと同材質、同じ厚み（約５ｍｍ）で形成されており、製作が容易となっている。なお、セラミックで形成する場合は、斜めに横切って連結した部分が中実体となる。   Further, as shown in FIG. 4, reinforcing members 2 are attached to the four corners of the frame body 1a so as to cross the corners diagonally and connect. As a result, the strength of the frame body 1a can be greatly improved, and even when the ceramic filter 11 is placed, the stability is increased, and the effect of sufficiently withstanding the weight is exhibited. The reinforcing member 2 is formed of the same material and the same thickness (about 5 mm) as the frame body 1a, and is easy to manufacture. In addition, when forming with a ceramic, the part connected across diagonally becomes a solid body.

このように構成したスペーサ１は、縦横複数列に並べたセラミックフィルタ群１２の各段間に挿入されて使用に供せられるものである点は従来と同様である。そして本発明では、多段に積層した熱交換器の１個のセラミックフィルタ１１と外径が同じ四角状の枠体１ａを複数個連結した構造であるので、セラミックフィルタ１１を所定の位置へ確実に載置できることとなる。また、セラミックフィルタ１１を外枠と補強部材の端面で支持しており、各セラミックフィルタ１１のガス流通部には何ら抵抗を生じさせない構造であるから、圧力損失を発生させることもない。しかも、熱衝撃や化学アタック等でセラミックフィルタが破損されて破壊粉が生じたとしても、スペーサ上に蓄積されることもなくなる。   The spacer 1 configured in this manner is the same as that of the prior art in that it is inserted between the stages of the ceramic filter group 12 arranged in a plurality of rows and columns. In the present invention, since a plurality of square frames 1a having the same outer diameter are connected to one ceramic filter 11 of a multi-layered heat exchanger, the ceramic filter 11 is surely moved to a predetermined position. It can be placed. In addition, since the ceramic filter 11 is supported by the outer frame and the end face of the reinforcing member and does not cause any resistance in the gas circulation portion of each ceramic filter 11, no pressure loss is generated. In addition, even if the ceramic filter is damaged by thermal shock, chemical attack, or the like to generate destructive powder, it is not accumulated on the spacer.

以上の説明からも明らかなように、本発明はセラミックフィルタ群を多段に積層した熱交換器の各段間に挿入される熱交換器用スペーサであって、１個のセラミックフィルタの外径と同一形状を有する四角状の枠体を縦方向および／または横方向に整列させて複数個連結した構造であり、スペーサを介在させることに起因する熱交換器の圧力損失の低減や異物の堆積の低減を図ることができることとなる。しかも、多段に積層するに際しては、熟練者でなくても誰もがセラミックフィルタをスペーサ上に正確かつ容易に載置することができるという利点や、更には簡単な構造であり、例えば現場等でも帯状の耐熱鋼材さえあれば短時間かつ安価に製作することができ、メンテナンス等も簡単にできるという利点もある。   As is clear from the above description, the present invention is a heat exchanger spacer inserted between each stage of a heat exchanger in which ceramic filter groups are laminated in multiple stages, and has the same outer diameter as one ceramic filter. A structure in which a plurality of rectangular frames having a shape are aligned in the vertical direction and / or the horizontal direction and connected to each other, and the pressure loss of the heat exchanger due to the interposition of the spacer and the reduction of foreign matter accumulation are reduced. Can be achieved. Moreover, when laminating in multiple stages, it is an advantage that anyone who is not an expert can place the ceramic filter accurately and easily on the spacer, and also has a simple structure. If there is only a belt-like heat-resistant steel material, it can be manufactured in a short time and at a low cost, and there is an advantage that maintenance and the like can be simplified.
