While the first corrugated fins 211 and 221 are set to have the same pitch, the second corrugated fins 216 and 226 are arranged out of phase with respect to the first corrugated fins 211 and 221.
- “arranged in phase” means the positions of the side walls 2113 and 2213 of the first corrugated fins 211 and 221 arranged in abutment and the positions of the side walls 2163 and 2263 of the second corrugated fins 216 and 226. Means that they are arranged so as to be displaced in the Z direction.
- the side walls 2163 and 2263 of the second corrugated fins 216 and 226 at the abutting end surfaces of the first corrugated fins 211 and 221 and the second corrugated fins 216 and 226 are the first corrugated fins 211 and 221.
- the second corrugated fins 216 and 226 are disposed so as to be positioned at the center between the side walls 2113 and 2213 of the first side.
- the amount of deviation is not limited to this.
- the end surfaces of the catalyst carriers 215 and 225 inserted into the channels come into contact with the side walls 2113 and 2213 of the second corrugated fins 216 and 226, and the catalyst carriers 215 and 225 can be positioned.
- the first modification has an advantage that the first corrugated fins 211 and 221 and the second corrugated fins 216 and 226 can be configured by the same corrugated fin.
- FIG. 4 shows a modification of the first and second corrugated fins.
- the first corrugated fins 217 and 227 and the second corrugated fins (that is, triangular fins) 218 and 228 arranged in the first passage 21 and the second passage 22 are the side walls 2173 and 2273, respectively.
- 2183, 2283 is configured to be inclined with respect to the Y direction, upper wall 2171, 2271, 2181, 2281, lower wall 2172, 2272, 2182, 2282, side wall 2173, 2273, 2183, 2283, and tube
- the cross section of each channel partitioned by the plate 23 is configured to be trapezoidal or inverted trapezoidal.
- the triangular fins 218 and 228 are arranged with the front and back reversed with respect to the first corrugated fins 217 and 227. This is equivalent to shifting the phase of the second corrugated fins 218 and 228 relative to the first corrugated fins 217 and 227 as in the first modification. Accordingly, as is apparent from FIG.
- the side walls 2183 and 2283 of the second corrugated fins 218 and 228 intersect with each other, and a part of the side walls 2183 and 2283 of the second corrugated fins 218 and 228 is connected to the side walls 2173 and 2273 is located between the two.
- the cross-sectional shape of the catalyst carrier 219, 229 is trapezoidal so as to correspond to the channel shape, but the cross-sectional shape of the catalyst carrier 219, 229 in Modification 4 is limited to this. Is not to be done. Also in this modification, the first corrugated fins 217 and 227 and the second corrugated fins 218 and 228 can be configured by the same corrugated fin.
- Modification 3 is a modification regarding the arrangement of the corrugated fins. As shown in FIG. 5, the first corrugated fin 211 in the first passage 21 is made shorter than the example of FIG. Further, another corrugated fin 214 is disposed between the one corrugated fin 211 and the triangular triangular fin 213, and the butted end surfaces of the first corrugated fin 211 and the corrugated fin 214 are connected to the catalyst carriers 215 and 225. Is set to positioning. That is, in Modification 3, the corrugated fin 214 corresponds to the second corrugated fin. In the illustrated example, the second corrugated fins 214 are constituted by fins having a smaller pitch than the first corrugated fins 211.
- the configuration of the first modification or the configuration of the second modification described above can be applied.
- illustration is abbreviate
- the triangular fin 213 and the second corrugated fin 214 are integrated with each other without forming the triangular fin 213 and the second corrugated fin 214 separately, and the trapezoidal corrugated fin as a whole. May be disposed between the first corrugated fins 211 and the distributor fins 212.
- FIGS. 1 and 2 The embodiment shown in FIGS. 1 and 2, the first modification shown in FIG. 3, the second modification shown in FIG. 4, and the third modification shown in FIG. 5 may be combined in a possible range.
- the configuration of the catalytic reactor described above is an example, and the present invention is not limited to this configuration.
- the catalyst reactor disclosed here suppresses the movement of the catalyst carrier inserted into the plurality of channels in the channels, and maintains the catalytic reaction well, while preventing the occurrence of drift. Since it can suppress, it is useful as a catalytic reactor utilized for various processes.

Abstract
Description
図3は、第2のコルゲートフィン(つまり、三角フィン)についての変形例を示している。この変形例では、上壁2161、2261、下壁2162、2262及び側壁2163、2263を有しかつ、それぞれ第1通路21及び第2通路22内に配置される第2のコルゲートフィン216、226が、第1のコルゲートフィン211、221と同じピッチに設定されている一方で、第2のコルゲートフィン216、226は、第1のコルゲートフィン211、221に対して位相をずらして配置されている。ここで「位相をずらして配置」とは、突き合わせて配設された第1のコルゲートフィン211、221の側壁2113、2213の位置と、第2のコルゲートフィン216、226の側壁2163、2263の位置とが、Z方向にずれるように配置することを意味する。図例では、第1のコルゲートフィン211、221と第2のコルゲートフィン216、226との突き合わせ端面において、第2のコルゲートフィン216、226の側壁2163、2263が、第1のコルゲートフィン211、221の側壁2113、2213同士の中央に位置するよう、第2のコルゲートフィン216、226を配設している。但し、ずれ量はこれに限らない。このことにより、各チャンネル内に挿入した触媒担持体215、225の端面が、第2のコルゲートフィン216、226の側壁2113、2213に当接するようになり、触媒担持体215、225の位置決めが可能になる。この変形例1では、第1のコルゲートフィン211、221と第2のコルゲートフィン216、226とを同じコルゲートフィンによって構成することが可能になるという利点がある。
図4は、第1及び第2コルゲートフィンの変形例を示している。この例では、第1通路21及び第2通路22内に配置される第1のコルゲートフィン217、227及び第2のコルゲートフィン(つまり、三角フィン)218、228はそれぞれ、その側壁2173,2273、2183,2283がY方向に対して傾斜するように構成されており、上壁2171、2271、2181、2281、下壁2172、2272、2182、2282、及び側壁2173,2273、2183,2283と、チューブプレート23とによって区画される各チャンネルの横断面は台形又は逆台形となるように構成されている。
変形例3は、コルゲートフィンの配置に関する変形例であり、図5に示すように、第1通路21における第1のコルゲートフィン211の長さを、図1の例よりも短くした上で、第1のコルゲートフィン211と、三角形状の三角フィン213との間に、さらに別のコルゲートフィン214を配置し、第1のコルゲートフィン211とコルゲートフィン214との突き合わせ端面を、触媒担持体215、225の位置決めに設定している。つまり、変形例3では、このコルゲートフィン214が、第2のコルゲートフィンに対応する。図例では、第2のコルゲートフィン214を、第1のコルゲートフィン211よりもピッチの小さいフィンによって構成している。但し、こうした第2のコルゲートフィンについては、前述した変形例1の構成や、変形例2の構成を適用することも可能である。尚、図示は省略するが、第2通路22についても、第1通路21と同様の構成を採用すればよい。
