ここで、吸着タンク６Ａは、図２に示すように、筐体６０と、吸着材６５と、供給流路７６Ａと、排出流路７１Ａと、を備える。吸着タンク６Ａは、図２および図３に示すように供給筒状部材７８Ａに配される供給シート部材６７Ｂ、排出筒状部材７３Ａに配される排出シート部材６７Ａをさらに備えてもよい。 Here, as shown in FIG. 2, the adsorption tank 6A includes a housing 60, an adsorption material 65, a supply flow path 76A, and a discharge flow path 71A. As shown in FIGS. 2 and 3, the suction tank 6A may further include a supply sheet member 67B arranged in the supply cylindrical member 78A and a discharge sheet member 67A arranged in the discharge cylindrical member 73A.

筐体６０は、例えば、ステンレス製の中空円柱型に構成され、円形の蓋部６１および底部６３と、円筒状の側壁部６２とを備える。蓋部６１は、筐体６０のうちの底部６３に対向する壁面を表す。 The housing 60 is, for example, configured in a hollow cylindrical shape made of stainless steel, and includes a circular lid portion 61 and a bottom portion 63, and a cylindrical side wall portion 62. The lid portion 61 represents a wall surface facing the bottom portion 63 of the housing 60.

供給流路７６Ａおよび排出流路７１Ａは、管路として構成されるとともに、蓋部６１を貫通するように構成される。供給流路７６Ａは、筐体６０内の一方側の端部にて対象ガスを吸着材６５に供給するように構成される。ここで、筐体６０内の一方側の端部とは、筐体６０を構成するある壁面に触れる位置、或いは、その近傍を表す。 The supply flow path 76A and the discharge flow path 71A are configured as a pipeline and are configured to penetrate the lid portion 61. The supply flow path 76A is configured to supply the target gas to the adsorbent 65 at one end of the housing 60. Here, the one-sided end portion in the housing 60 represents a position where the housing 60 touches a certain wall surface or a vicinity thereof.

つまり、筐体６０内の一方側の端部とは、筐体６０の内壁面に接触して配置された吸着材６５に、対象ガスや外気を行き渡らせることができる程度の位置を示す。本実施形態では、蓋部６１の近くにて対象ガスを吸着材６５に供給するように構成される。 That is, the one end portion in the housing 60 indicates a position where the target gas and the outside air can be distributed to the adsorbent 65 arranged in contact with the inner wall surface of the housing 60. In the present embodiment, the target gas is supplied to the adsorbent 65 near the lid portion 61.

供給流路７６Ａは、蓋部６１と平行に対象ガスを流しつつ、対象ガスを供給するように構成される。ここで平行とは、厳密な意味での平行に限るものではなく、上記と同様の効果を奏するのであれば厳密に平行でなくてもよい。 The supply flow path 76A is configured to supply the target gas while flowing the target gas in parallel with the lid portion 61. Here, parallelism is not limited to parallelism in a strict sense, and may not be strictly parallel as long as it has the same effect as described above.

供給流路７６Ａは、吸着材６５側に供給筒状部材７８Ａを備える。
供給筒状部材７８Ａは、供給流路７６Ａに対して接続部７７を介して接続された筒状の部材であり、蓋部６１と平行なある方向が菅の長手方向になるように配置され、この長手方向に沿って複数の孔部７８Ｈが形成されている。 The supply flow path 76A includes a supply tubular member 78A on the adsorbent 65 side.
The supply tubular member 78A is a tubular member connected to the supply flow path 76A via a connecting portion 77, and is arranged so that a certain direction parallel to the lid portion 61 is the longitudinal direction of the tube. A plurality of holes 78H are formed along this longitudinal direction.

また、供給筒状部材７８Ａは、長手方向のほぼ中央に接続部７７を備える構成であり、接続部７７は対象ガスを２方向に分岐させる分岐部として機能する。この構成により、対象ガスがより拡散するよう考慮されている。 Further, the supply cylindrical member 78A has a configuration in which the connecting portion 77 is provided substantially in the center in the longitudinal direction, and the connecting portion 77 functions as a branching portion for branching the target gas in two directions. With this configuration, consideration is given to the target gas being more diffused.

なお、孔部７８Ｈは、接続部７７よりも先端側に配置され、かつ接続部７７からやや隔てて配置される。対象ガスの流路が曲がる場合、流路が曲がる部位に対象ガスが多く当たり、圧力が高くなる。この部位に孔部７８Ｈを設けると、その孔部から多くの対象ガスが供給されるため、流路の形状により対象ガスの圧力が高くなる部位に孔部７８Ｈを設けないように構成される。 The hole 78H is arranged on the tip side of the connecting portion 77 and slightly separated from the connecting portion 77. When the flow path of the target gas bends, a large amount of the target gas hits the portion where the flow path bends, and the pressure increases. If the hole 78H is provided in this portion, a large amount of the target gas is supplied from the hole, so that the hole 78H is not provided in the portion where the pressure of the target gas increases due to the shape of the flow path.

複数の孔部７８Ｈは、吸着タンク６Ａの長手方向に対して直交する方向において、供給流路７６Ａに近いほうから遠いほうに向かって徐々に穴径が大きくなる。換言すれば、複数の孔部７８Ｈは、供給筒状部材７８Ａの先端部に近づくにつれて徐々に穴径が大きくなるように構成される。つまり、概ね同量の対象ガスが各孔部７８Ｈを通過するように、供給筒状部材７８Ａ内の対象ガスの圧力に応じて、各孔部７８Ｈが異なる穴の面積に設定される。 The hole diameters of the plurality of holes 78H gradually increase from the side closer to the supply flow path 76A to the side farther from the supply flow path 76A in the direction orthogonal to the longitudinal direction of the suction tank 6A. In other words, the plurality of hole portions 78H are configured so that the hole diameter gradually increases as they approach the tip end portion of the supply cylindrical member 78A. That is, each hole 78H is set to a different hole area according to the pressure of the target gas in the supply cylindrical member 78A so that substantially the same amount of the target gas passes through each hole 78H.

ここで、供給筒状部材７８Ａの先端部とは、供給筒状部材７８Ａにおいて対象ガスの流れ方向の下流側を示す。なお、排出筒状部材７３Ａの先端側とは、排出筒状部材７３Ａにおいて対象ガスの流れ方向の上流側を示す。 Here, the tip end portion of the supply tubular member 78A indicates the downstream side of the supply tubular member 78A in the flow direction of the target gas. The tip end side of the discharge cylinder-shaped member 73A indicates the upstream side of the discharge cylinder-shaped member 73A in the flow direction of the target gas.

この構成では、供給筒状部材７８Ａのうちの対象ガスの圧力が高い接続部７７付近の部位で、孔部７８Ｈの穴径が小さく設定されるので、孔部７８Ｈを介した対象ガスの出入りが抑制される。また、供給筒状部材７８Ａのうちの対象ガスの圧力が低い先端部付近の部位で、孔部７８Ｈの穴径が大きく設定されるので、孔部７８Ｈを介した対象ガスの出入りが促進される。この結果、各孔部７８Ｈを出入りする対象ガスの量の差を小さくすることができる。そして、吸着材６５中の各部を通過する対象ガスの量を概ね均一化することができる。よって、吸着材６５全体に二酸化炭素を良好に吸着させることができる。 In this configuration, the hole diameter of the hole 78H is set small at the portion of the supply cylindrical member 78A near the connection portion 77 where the pressure of the target gas is high, so that the target gas enters and exits through the hole 78H. It is suppressed. Further, since the hole diameter of the hole 78H is set large in the portion of the supply cylindrical member 78A near the tip where the pressure of the target gas is low, the inflow and outflow of the target gas through the hole 78H is promoted. .. As a result, the difference in the amount of the target gas entering and exiting each hole 78H can be reduced. Then, the amount of the target gas passing through each part in the adsorbent 65 can be made substantially uniform. Therefore, carbon dioxide can be satisfactorily adsorbed on the entire adsorbent 65.

排出流路７１Ａは、筐体６０内の他方側の端部にて筐体６０内から対象ガスを排出するように構成される。筐体６０内の他方側の端部とは、前述の一方側の端部と対向する壁面に触れる位置、或いはその近傍であって、筐体６０の内壁面に接触して配置された吸着材６５に、対象ガスまたは外気を行き渡らせることができる程度の位置を示す。本実施形態では、底部６３の近くにて筐体６０内の対象ガスを排出するように構成される。 The discharge flow path 71A is configured to discharge the target gas from the inside of the housing 60 at the other end of the housing 60. The other end of the housing 60 is a position that touches or is near the wall surface facing the one side end, and is an adsorbent arranged in contact with the inner wall surface of the housing 60. Reference numeral 65 indicates a position at which the target gas or the outside air can be distributed. In the present embodiment, the target gas in the housing 60 is configured to be discharged near the bottom 63.

排出流路７１Ａは、筐体６０の底部６３側の端部にて底部６３と垂直、つまり鉛直方向に対象ガスを流しつつ、対象ガスを排出するように構成される。
排出流路７１Ａは、吸着材６５側に排出筒状部材７３Ａを備える。 The discharge flow path 71A is configured to discharge the target gas while flowing the target gas perpendicular to the bottom portion 63, that is, in the vertical direction at the end portion of the housing 60 on the bottom 63 side.
The discharge flow path 71A includes a discharge cylinder-shaped member 73A on the adsorbent 65 side.

排出筒状部材７３Ａは、排出流路７１Ａに対して接続部７２を介して接続された筒状の部材であり、底部６３に沿って配置される。排出筒状部材７３Ａは、供給筒状部材７８Ａと同様に、排出筒状部材７３Ａの全長における中央に接続部７２を備える構成であり、接続部７２は流路を２方向に分岐させる分岐部として機能する。 The discharge cylindrical member 73A is a tubular member connected to the discharge flow path 71A via a connecting portion 72, and is arranged along the bottom portion 63. Like the supply cylinder-shaped member 78A, the discharge cylinder-shaped member 73A has a configuration in which a connecting portion 72 is provided at the center of the entire length of the discharge cylinder-shaped member 73A, and the connecting portion 72 serves as a branching portion for branching the flow path in two directions. Function.

排出筒状部材７３Ａは、接続部７２付近で流路が供給筒状部材７８Ａの長手方向と平行に構成されるが、２か所の屈曲部７３Ｌによって供給筒状部材７８Ａの長手方向とは直交する方向に管路が曲げられて構成される。 In the discharge cylindrical member 73A, the flow path is configured to be parallel to the longitudinal direction of the supply tubular member 78A near the connection portion 72, but the two bent portions 73L are orthogonal to the longitudinal direction of the supply tubular member 78A. The pipeline is bent in the direction of the pipe.

排出筒状部材７３Ａは、屈曲部７３Ｌよりも先端側に、複数の孔部７３Ｈを備える。複数の孔部７３Ｈは、排出筒状部材７３Ａの屈曲部７３Ｌよりも先端側における菅の長手方向に沿って形成される。この長手方向を排出筒状部材７３Ａの長手方向とすると、供給筒状部材７８Ａの長手方向と排出筒状部材７３Ａの長手方向とは直交するように配置される。 The discharge cylinder-shaped member 73A is provided with a plurality of hole portions 73H on the tip end side of the bent portion 73L. The plurality of hole portions 73H are formed along the longitudinal direction of the tube on the distal end side of the bent portion 73L of the discharge cylinder-shaped member 73A. Assuming that the longitudinal direction is the longitudinal direction of the discharge cylindrical member 73A, the longitudinal direction of the supply tubular member 78A and the longitudinal direction of the discharge tubular member 73A are arranged so as to be orthogonal to each other.

供給シート部材６７Ｂは、供給筒状部材７８Ａが備える孔部７８Ｈの全てを覆い、通気性を有するように構成される。また、排出シート部材６７Ａは、排出筒状部材７３Ａが備える孔部７３Ｈの全てを覆い、通気性を有するように構成される。供給シート部材６７Ｂおよび排出シート部材６７Ａは、例えば、不織布等によって構成される。 The supply sheet member 67B covers all of the holes 78H included in the supply cylindrical member 78A and is configured to have air permeability. Further, the discharge sheet member 67A is configured to cover all the holes 73H included in the discharge cylinder-shaped member 73A and have air permeability. The supply sheet member 67B and the discharge sheet member 67A are made of, for example, a non-woven fabric or the like.

なお、吸着タンク６を組み立てる際には、まず、筐体６０の蓋部６１を分離し、筐体６０が底部６３および側壁部６２を有する状態で、排出筒状部材７３Ａを含む排出流路７１Ａを底部６３付近に設置する。そして、この状態で筐体６０の内部を隙間なく吸着材６５で満たし、供給筒状部材７８Ａを含む供給流路７６Ａを吸着材６５の上から吸着材６５に埋没するように設置する。最後に、蓋部６１を閉じる。このように筐体６０の内部が吸着材６５で満たされるようにするとよい。 When assembling the suction tank 6, first, the lid portion 61 of the housing 60 is separated, and the housing 60 has the bottom portion 63 and the side wall portion 62, and the discharge flow path 71A including the discharge cylinder-shaped member 73A is included. Is installed near the bottom 63. Then, in this state, the inside of the housing 60 is filled with the adsorbent 65 without any gap, and the supply flow path 76A including the supply tubular member 78A is installed so as to be buried in the adsorbent 65 from above the adsorbent 65. Finally, the lid portion 61 is closed. In this way, the inside of the housing 60 may be filled with the adsorbent 65.

At least one of the supply flow path 76A and the discharge flow path 71A further includes a supply cylinder-shaped member 78A and a discharge cylinder-shaped member 73A on the adsorbent 65 side of the flow path. The supply cylindrical member 78A and the discharge cylindrical member 73A are members configured in a cylindrical shape, and one or a plurality of holes 73H configured to supply or discharge the target gas along the longitudinal direction of the member. , 78H.

このような二酸化炭素施用装置１Ａによれば、筐体６０の端部にて対象ガスを供給および排出し、少なくとも一方は長手方向に沿った孔部７３Ｈ，７８Ｈを備えるので、吸着タンク６内に対象ガスを行き渡らせつつ、吸着材６５の充填率を向上させることができる。 According to such a carbon dioxide application device 1A, the target gas is supplied and discharged at the end of the housing 60, and at least one of the carbon dioxide application devices 1A is provided with holes 73H and 78H along the longitudinal direction. The filling rate of the adsorbent 65 can be improved while spreading the target gas.

（１ｂ）上記の二酸化炭素施用装置１Ａの吸着タンク６Ａにおいて、供給流路７６Ａおよび排出流路７１Ａは、筐体６０の蓋部６１付近において蓋部６１側、若しくは筐体６０の底部６３側の端部にて底部６３と平行に対象ガスを流しつつ、対象ガスを供給または排出するように構成され、供給流路７６Ａおよび排出流路７１Ａのうちの他方は、底部６３に対向する蓋部６１側の端部にて蓋部６１と平行に対象ガスを流しつつ、対象ガスを供給または排出するように構成される。 (1b) In the adsorption tank 6A of the carbon dioxide application device 1A, the supply flow path 76A and the discharge flow path 71A are located on the lid portion 61 side or the bottom portion 63 side of the housing 60 in the vicinity of the lid portion 61 of the housing 60.

It is configured to supply or discharge the target gas while flowing the target gas in parallel with the lid portion 61 at the end portion on the side.

このような二酸化炭素施用装置１Ａによれば、対象ガスが供給流路７６Ａから排出流路７１Ａに至るまでに、対象ガスは筐体６０内で対象ガスの流れが鉛直方向下側に対して方向転換しつつ流れるので、対象ガスが吸着材６５内で拡散しやすくすることができる。よって、吸着タンク６Ａでの二酸化炭素の吸着量を向上させることができる。 According to such a carbon dioxide application device 1A, the flow of the target gas in the housing 60 is directed downward in the vertical direction by the time the target gas reaches the supply flow path 76A to the discharge flow path 71A. Since it flows while being converted, the target gas can be easily diffused in the adsorbent 65. Therefore, the amount of carbon dioxide adsorbed in the adsorption tank 6A can be improved.

It may be processed to penetrate. Therefore, the work of filling the adsorbent 65 and the work of assembling the supply flow path 76A and the discharge flow path 71A to the housing 60 can be easily performed.

（１ｄ）上記の二酸化炭素施用装置１Ａの吸着タンク６Ａは、供給シート部材６７Ｂ、排出シート部材６７Ａをさらに備える。供給シート部材６７Ｂ、排出シート部材６７Ａは、供給筒状部材７８Ａ、排出筒状部材７３Ａが備える孔部７３Ｈ，７８Ｈを覆い、通気性を有するように構成される。 (1d) The adsorption tank 6A of the carbon dioxide application device 1A further includes a supply sheet member 67B and a discharge sheet member 67A. The supply sheet member 67B and the discharge sheet member 67A cover the holes 73H and 78H provided in the supply cylinder-shaped member 78A and the discharge cylinder-shaped member 73A, and are configured to have air permeability.

このような二酸化炭素施用装置１Ａによれば、通気性を有する供給シート部材６７Ｂ、排出シート部材６７Ａを備えるので、対象ガスの供給または排出を阻害することなく、孔部７３Ｈ，７８Ｈへ吸着材６５が侵入することを抑制することができる。 According to such a carbon dioxide application device 1A, since the supply sheet member 67B and the discharge sheet member 67A having air permeability are provided, the adsorbent 65 to the holes 73H and 78H without obstructing the supply or discharge of the target gas. Can be suppressed from invading.

（１ｅ）上記の二酸化炭素施用装置１Ａの吸着タンク６Ａは、供給流路７６Ａに供給筒状部材７８Ａを備え、排出流路７１Ａに排出筒状部材７３Ａを備える。また、供給シート部材６７Ｂは、供給筒状部材７８Ａが有する孔部７８Ｈを覆い、排出シート部材６７Ａは、排出筒状部材７３Ａが有する孔部７３Ｈを覆うように構成される。 (1e) The adsorption tank 6A of the carbon dioxide application device 1A includes a supply cylinder-shaped member 78A in the supply flow path 76A and a discharge cylinder-shaped member 73A in the discharge flow path 71A. Further, the supply sheet member 67B is configured to cover the hole 78H of the supply cylinder member 78A, and the discharge sheet member 67A is configured to cover the hole 73H of the discharge cylinder member 73A.

In particular, even in a configuration in which the flow of the target gas changes between the time of adsorbing carbon dioxide and the time of desorption, it is possible to suppress the invasion of the adsorbent 65 into each flow path.

（１ｆ）上記の二酸化炭素施用装置１Ａの吸着タンク６Ａは、供給筒状部材７８Ａの長手方向に沿って複数の孔部７８Ｈを備え、複数の孔部７８Ｈは、供給筒状部材７８Ａの先端部に近づくにつれて徐々に穴径が大きくなるように構成される。 (1f) The adsorption tank 6A of the carbon dioxide application device 1A includes a plurality of holes 78H along the longitudinal direction of the supply tubular member 78A, and the plurality of holes 78H are the tip portions of the supply tubular member 78A. It is configured so that the hole diameter gradually increases as it approaches.

このような二酸化炭素施用装置１Ａによれば、供給筒状部材７８Ａのうちの対象ガスの圧力が高い接続部７７付近の部位では、孔部７８Ｈの穴径が小さく設定されるので、孔部７８Ｈを介した対象ガスの出入りを抑制することができる。また、供給筒状部材７８Ａのうちの対象ガスの圧力が低い先端部付近の部位では、孔部７８Ｈの穴径が大きく設定されるので、孔部７８Ｈを介した対象ガスの出入りを促進することができる。この結果、各孔部７８Ｈを出入りする対象ガスの量の差を小さくすることができる。 According to such a carbon dioxide application device 1A, the hole diameter of the hole 78H is set small in the portion of the supply cylindrical member 78A near the connection portion 77 where the pressure of the target gas is high, so that the hole 78H It is possible to suppress the inflow and outflow of the target gas through the gas. Further, since the hole diameter of the hole 78H is set large in the portion of the supply cylindrical member 78A near the tip where the pressure of the target gas is low, the inflow and outflow of the target gas through the hole 78H should be promoted. Can be done. As a result, the difference in the amount of the target gas entering and exiting each hole 78H can be reduced.

このような構成によれば、複数の孔部７３Ｈ，７８Ｈから流出、或いは複数の孔部７３Ｈ，７８Ｈに流入する対象ガスの量の差を小さくすることができるので、吸着材６５中の各部を通過する対象ガスの量を概ね均一化することができる。よって、吸着材６５全体に二酸化炭素を良好に吸着させることができる。 According to such a configuration, it is possible to reduce the difference in the amount of the target gas flowing out from the plurality of holes 73H and 78H or flowing into the plurality of holes 73H and 78H. The amount of target gas that passes through can be made almost uniform. Therefore, carbon dioxide can be satisfactorily adsorbed on the entire adsorbent 65.

Note that FIG. 5 shows only the discharge cylinder-shaped member 73B, and FIG. 6 shows only the supply cylinder-shaped member 78B.

具体的には、排出筒状部材７３Ｂは、図５に示すように、接続部７２を中心として、底部６３の直径方向である２方向に流路が分岐され、それぞれの分岐された流路は、それぞれ９０ｄｅｇずつ管路を屈曲させる２か所の屈曲部７３ＬにてＳ字状になるように曲げられる。ただし、ｄｅｇは度数法での角度を表すdegreeの略である。 Specifically, as shown in FIG. 5, in the discharge cylinder-shaped member 73B, the flow path is branched in two directions, which is the diameter direction of the bottom portion 63, with the connection portion 72 as the center, and each branched flow path is , 90 deg each is bent so as to be S-shaped at two bending portions 73L that bend the pipeline.
