　本発明は、ガス分離装置用充填材及びガス分離装置に関し、特に、排ガス等の未処理ガスに含まれる二酸化炭素等の分離対象ガスを反応液と化学反応させて未処理ガスから分離又は回収するためのガス分離装置用充填材及びガス分離装置に関する。 The present invention relates to a filler for a gas separation device and a gas separation device, and in particular, separates or collects a separation target gas such as carbon dioxide contained in an untreated gas such as exhaust gas from the untreated gas by chemically reacting with a reaction solution. The present invention relates to a gas separation device filler and a gas separation device.
　従来、化学プラントや火力発電所等において、様々な種類のガスを含む排ガス等の未処理ガスから特定のガスを分離するガス分離装置（例えば、蒸留塔、吸収塔、精製塔等）が使用されている。これらのガス分離装置は、モノエタノールアミン水溶液等の反応液と二酸化炭素等の分離対象ガスとを化学反応させることによって分離対象ガスを分離又は回収する。また、ガス分離装置は、反応液と分離対象ガスとの接触面積を増大させる充填材を有し、該充填材表面で反応液と分離対象ガスとを気液接触させて化学反応させていることから、気液接触装置と称されることもある。かかるガス分離装置（気液接触装置）は、一般に、多数の板材を傾斜配置又は鉛直配置して構成されることが多い（例えば、特許文献１～特許文献３参照）。 Conventionally, gas separation devices (for example, distillation towers, absorption towers, purification towers, etc.) that separate specific gases from untreated gases such as exhaust gases containing various types of gases have been used in chemical plants and thermal power plants. ing. These gas separation devices separate or recover the separation target gas by chemically reacting a reaction liquid such as a monoethanolamine aqueous solution and a separation target gas such as carbon dioxide. Further, the gas separation device has a filler that increases the contact area between the reaction liquid and the separation target gas, and causes the reaction liquid and the separation target gas to be in a gas-liquid contact on the surface of the filling material to cause a chemical reaction. Therefore, it may be referred to as a gas-liquid contact device. In general, such a gas separation device (gas-liquid contact device) is often configured by arranging a large number of plate members in an inclined arrangement or a vertical arrangement (for example, see Patent Documents 1 to 3).
　例えば、特許文献１に記載されたガス分離装置（気液接触装置）は、気液接触装置内に充填される充填物の断面が各種形状の管状構造体であり、その管状部は直線状を示し、その気液接触面を気体の流れに対し平行になるように多数配置し、その充填物の上方から液体を供給し、供給された液体を充填物表面に添って流下させるとともに、下部から気体を供給して気体と液体とを接触させる気液接触装置において、前記気液接触面の中心線平均粗さが５０μｍ以上である粗面部を有することを特徴としている。 For example, the gas separation device (gas-liquid contact device) described in Patent Document 1 is a tubular structure having various shapes in the cross-section of the filling material filled in the gas-liquid contact device, and the tubular portion has a linear shape. A large number of gas-liquid contact surfaces are arranged so as to be parallel to the gas flow, liquid is supplied from above the packing, and the supplied liquid flows down along the surface of the packing, and from the bottom. In the gas-liquid contact device for supplying gas and bringing the gas and liquid into contact with each other, the gas-liquid contact surface has a rough surface portion having a center line average roughness of 50 μm or more.
　また、特許文献２に記載されたガス分離装置（気液接触装置）は、特許文献１と同等の構成を有する気液接触装置において、前記充填物の水平断面が円、円弧又は円弧の連続的結合、互いに交差しない直線又は接触しない直線の群から選ばれる形状からなることを特徴とし、前記充填物は、例えば、放射状に形成されたり、半径が次第に大きくなる又は小さくなる円弧を連続的に結合した螺旋形に形成されたりしている。 In addition, the gas separation device (gas-liquid contact device) described in Patent Document 2 is a gas-liquid contact device having a configuration equivalent to that of Patent Document 1, and the horizontal cross section of the packing is a continuous circle, arc, or arc. The filler is formed of a shape selected from a group of bonds, straight lines that do not intersect with each other, or straight lines that do not contact each other, and the filler is formed, for example, in a radial manner, or continuously connects circular arcs whose radius gradually increases or decreases It is formed in a spiral shape.
　また、特許文献３に記載された充填材は、断面が三角形状に折り曲げられたシート状基材と、エンボス加工によって前記シート状基材の両面に形成された複数の突起と、前記シート状基材を貫通して形成された複数の孔部と、を備え、前記シート状基材に沿って流れる流体が前記突起及び前記孔部により前記シート状基材の表裏両面全域にわたって均一化された流量分布で分配されることを特徴とし、前記シート基材を重ね合わせることにより又はスパイラル状に捲き回すことにより、充填材集合体を形成している。 Further, the filler described in Patent Document 3 includes a sheet-like base material having a triangular cross-section, a plurality of protrusions formed on both sides of the sheet-like base material by embossing, and the sheet-like base material. A plurality of holes formed through the material, and the flow rate of fluid flowing along the sheet-like base material is made uniform across the entire front and back surfaces of the sheet-like base material by the protrusions and the holes. It is characterized by being distributed in a distribution, and the filler aggregate is formed by overlapping the sheet base materials or by rolling them in a spiral shape.

When the filler is configured by arranging a large number of plates vertically, a large number of plates may be joined. In addition, many plate materials must be fixed at regular intervals, making the production and installation of fillers complicated, and requiring time and labor to manufacture and install gas separation devices (gas-liquid contact devices). However, there is a problem that it becomes a factor of cost increase. In addition, Patent Document 2 and Patent Document 3 describe that the filler is formed in a spiral shape or a spiral shape, but the shape of the outer shape is not stable, and it takes time and labor to manufacture and install the filler. In short, there is a problem that it becomes a factor of cost increase.
