本明細書に開示の技術はガス吸着装置に関する。 The technology disclosed herein relates to a gas adsorption device.

従来、例えば特許文献１に記載されたガス吸着装置がある。そのガス吸着装置は、吸着物質を吸着する吸着材と、吸着材を収容する吸着容器と、吸着容器に向けて電磁波を照射することにより吸着材を誘電加熱する電磁波発生装置と、を備える。吸着物質の脱離時に吸着材を誘電加熱することにより、吸着物質の脱離を促進する。 Conventionally, there is a gas adsorption device described in Patent Document 1, for example. The gas adsorption device includes an adsorbent that adsorbs an adsorbent, an adsorption container that houses the adsorbent, and an electromagnetic wave generator that dielectrically heats the adsorbent by irradiating electromagnetic waves toward the adsorption container.

特開平１０－３０５２０７号公報Japanese Patent Application Publication No. 10-305207

特許文献１によると、吸着容器が一層構造の容器であるため、吸着物質の脱離時に吸着材を加熱しても、その吸着材の熱が吸着容器に奪われやすい。したがって、吸着材の温度が低下しやすく、脱離の促進が損なわれるという問題があった。 According to Patent Document 1, since the adsorption container has a single-layer structure, even if the adsorbent is heated during desorption of the adsorbent, the heat of the adsorbent is easily absorbed by the adsorption container. Therefore, there has been a problem that the temperature of the adsorbent tends to drop, impairing the promotion of desorption.

本明細書に開示の技術が解決しようとする課題は、吸着物質の脱離時における吸着材の温度の低下を抑制し、脱離効率を向上することにある。 The problem to be solved by the technology disclosed in this specification is to suppress a decrease in the temperature of an adsorbent during desorption of an adsorbent and to improve desorption efficiency.

上記課題を解決するため、本明細書が開示する技術は次の手段をとる。 In order to solve the above problems, the technology disclosed in this specification takes the following measures.

第１の手段は、吸着物質を吸着する吸着材と、前記吸着材を収容する吸着容器と、前記吸着容器に向けて電磁波を照射することにより前記吸着材を誘電加熱する電磁波発生装置と、を備えるガス吸着装置であって、前記吸着容器は、容器本体と、該容器本体の少なくとも前記電磁波が照射される部分と前記吸着材との間に設けられる温度低下抑制部材と、を有しており、前記温度低下抑制部材は、前記容器本体の誘電損失係数よりも大きい誘電損失係数を有する、ガス吸着装置である。 A first means includes an adsorbent that adsorbs an adsorbent, an adsorption container that houses the adsorbent, and an electromagnetic wave generator that dielectrically heats the adsorbent by irradiating electromagnetic waves toward the adsorption container. In the gas adsorption device, the adsorption container includes a container main body, and a temperature drop suppressing member provided between at least a portion of the container main body that is irradiated with the electromagnetic wave and the adsorbent. , the temperature drop suppressing member is a gas adsorption device having a dielectric loss coefficient larger than a dielectric loss coefficient of the container body.

第１の手段によると、吸着物質の脱離時において、電磁波発生装置により吸着材を誘電加熱した際、吸着容器の容器本体は誘電加熱されない又は誘電加熱されにくいが、吸着容器の温度低下抑制部材は誘電加熱される。これにより、温度低下抑制部材の熱が吸着容器の容器本体に奪われるとしても、温度低下抑制部材の近傍の吸着材の温度の低下を抑制することができる。よって、脱離効率を向上することができる。 According to the first means, when the adsorbent is dielectrically heated by the electromagnetic wave generator during the desorption of the adsorbent, the container body of the adsorption container is not dielectrically heated or is not easily dielectrically heated, but the temperature drop suppressing member of the adsorption container is dielectrically heated. Thereby, even if the heat of the temperature drop suppressing member is taken away by the container body of the adsorption container, it is possible to suppress a decrease in the temperature of the adsorbent near the temperature drop suppressing member. Therefore, desorption efficiency can be improved.

第２の手段は、吸着物質を吸着する吸着材と、前記吸着材を収容する吸着容器と、前記吸着容器に向けて電磁波を照射することにより前記吸着材を誘電加熱する電磁波発生装置と、を備えるガス吸着装置であって、前記吸着容器は、容器本体と、該容器本体の内側に設けられる容器内壁と、を備えており、前記容器本体と前記容器内壁との間には、液体を貯留可能でかつ該液体を注入及び排出可能な貯留部が設けられている、ガス吸着装置である。 A second means includes an adsorbent that adsorbs an adsorbent, an adsorption container that houses the adsorbent, and an electromagnetic wave generator that dielectrically heats the adsorbent by irradiating electromagnetic waves toward the adsorption container. The adsorption device includes a container body and a container inner wall provided inside the container body, and a liquid is stored between the container body and the container inner wall. The gas adsorption device is provided with a reservoir that is capable of injecting and draining the liquid.

第２の手段によると、吸着容器の貯留部に液体を注入により貯留した状態で、吸着物質の脱離を行う。吸着物質の脱離時において、電磁波発生装置により吸着材を誘電加熱した際、吸着容器の容器本体及び容器内壁は誘電加熱されない又は誘電加熱されにくいが、液体は誘電加熱される。これにより、液体の熱が容器本体に奪われるとしても、容器内壁の近傍の吸着材の温度の低下を抑制することができる。よって、脱離効率を向上することができる。また、吸着物質の脱離後、貯留部の液体を排出することにより、吸着容器の温度低下を促進し、次回の吸着工程までのリードタイムを短縮することができる。また、容器内壁は、誘電加熱されない材料、容器本体と同等の材料、容器本体と比べて誘電加熱されにくい材料、容器本体と比べて誘電加熱されやすい材料、のいずれの材料で形成してもよい。 According to the second method, the adsorbed substance is desorbed while the liquid is injected and stored in the storage part of the adsorption container. When the adsorbent is dielectrically heated by an electromagnetic wave generator during desorption of the adsorbent, the main body and inner wall of the adsorption container are not dielectrically heated or hardly dielectrically heated, but the liquid is dielectrically heated. Thereby, even if the heat of the liquid is taken away by the container body, it is possible to suppress a decrease in the temperature of the adsorbent near the inner wall of the container. Therefore, desorption efficiency can be improved. Further, by discharging the liquid in the storage section after the adsorption substance is desorbed, it is possible to promote the temperature reduction of the adsorption container and shorten the lead time until the next adsorption step. Furthermore, the inner wall of the container may be formed of any of the following materials: a material that is not dielectrically heated, a material that is equivalent to the container body, a material that is less dielectrically heated than the container body, and a material that is more easily dielectrically heated than the container body. .

第３の手段は、第１又は第２の手段のガス吸着装置であって、前記吸着容器は、前記容器本体の少なくとも一部を覆う断熱部材を備えている、ガス吸着装置である。 A third means is the gas adsorption device of the first or second means, in which the adsorption container is provided with a heat insulating member that covers at least a portion of the container body.

第３の手段によると、断熱部材により吸着容器の容器本体を保温することができる。 According to the third means, the container body of the adsorption container can be kept warm by the heat insulating member.

本明細書に開示の技術によると、吸着物質の脱離時における吸着材の温度の低下を抑制し、脱離効率を向上することができる。 According to the technology disclosed in this specification, it is possible to suppress a decrease in the temperature of an adsorbent during desorption of an adsorbent and improve desorption efficiency.

The adsorption container 12 is formed into a vertical hollow cylindrical shape. An upper opening 13a is provided at the upper end of the adsorption container 12 to communicate the inside and outside of the adsorption container 12. A lower opening 13b is provided at the lower end of the adsorption container 12 to communicate the inside and outside of the adsorption container 12. In this embodiment, the upper port 13a is used as a gas inlet for the mixed gas, and the lower port 13b is used as a gas outlet. The mixed gas is, for example, the atmosphere, exhaust gas from a combustion engine, or the like. Details of the adsorption container 12 will be explained later.

（吸着材１６）
吸着材１６は、吸着容器１２内に充填されて収容されている。吸着材１６は、例えば、二酸化炭素（ＣＯ2）等の吸着物質を吸着及び脱離可能である。吸着材１６には、誘電加熱されやすい物質が用いられる。吸着材１６は、例えば、ゼオライト、シリカゲル、活性炭等からなる。吸着材１６の形状は、例えば、粒状、ペレット状、粉末状、ハニカム状等である。 (Adsorbent 16)
The adsorbent 16 is filled and housed in the adsorption container 12. The adsorbent 16 is capable of adsorbing and desorbing adsorbent substances such as carbon dioxide (CO2), for example. For the adsorbent 16, a substance that is easily dielectrically heated is used. The adsorbent 16 is made of, for example, zeolite, silica gel, activated carbon, or the like. The shape of the adsorbent 16 is, for example, granular, pellet, powder, honeycomb, or the like.

（電磁波発生装置１８）
電磁波発生装置１８は、吸着物質の脱離時において、電磁波（図１中、矢印参照）を吸着容器１２に向けて照射することにより吸着材１６及び吸着容器１２を誘電加熱する。 (Electromagnetic wave generator 18)
The electromagnetic wave generator 18 dielectrically heats the adsorbent 16 and the adsorption container 12 by irradiating the adsorption container 12 with electromagnetic waves (see arrows in FIG. 1) during desorption of the adsorbent.

（吸着容器１２の構造）
図１に示すように、吸着容器１２は、容器本体１３と温度低下抑制部材１４とを有する。容器本体１３は、吸着容器１２の主体をなすものであり、上部口１３ａ及び下部口１３ｂを有する。容器本体１３は、例えば、ポリテトラフルオロエチレン（ＰＴＦＥ）樹脂、石英ガラス等により形成されている。なお、図２は吸着容器を一部破断して示す斜視図である。 (Structure of adsorption container 12)
As shown in FIG. 1, the adsorption container 12 includes a container body 13 and a temperature drop suppressing member 14.

温度低下抑制部材１４は、容器本体１３の内周面を略全面的に覆うように円筒状に形成されている。温度低下抑制部材１４は、容器本体１３の誘電損失係数よりも大きい誘電損失係数を有する。すなわち、温度低下抑制部材１４は、容器本体１３と比べて、誘電加熱されやすい材料により形成されている。言い換えれば、容器本体１３は、温度低下抑制部材１４と比べて、誘電加熱されにくい材料により形成されている。温度低下抑制部材１４は、例えばアルミナ等により形成されている。温度低下抑制部材１４は、容器本体１３の少なくとも電磁波が照射される部分の内壁面に設けられていればよい。 The temperature drop suppressing member 14 is formed in a cylindrical shape so as to substantially entirely cover the inner circumferential surface of the container body 13. The temperature drop suppressing member 14 has a dielectric loss coefficient larger than that of the container body 13. That is, the temperature drop suppressing member 14 is made of a material that is more easily dielectrically heated than the container body 13. In other words, the container body 13 is made of a material that is less susceptible to dielectric heating than the temperature drop suppressing member 14 . The temperature drop suppressing member 14 is made of, for example, alumina. The temperature drop suppressing member 14 may be provided on the inner wall surface of at least a portion of the container body 13 that is irradiated with electromagnetic waves.

（ガス吸着装置１０の作用）
〈吸着時〉
吸着物質（二酸化炭素）を含む混合ガスが混合ガス供給源から上部口１３ａを介して吸着容器１２に導入され、下部口１３ｂから導出される。その際、吸着物質が吸着材１６に吸着される。その後、吸着物質が除去されたガスは、下部口１３ｂから供給先へ供給される。 (Operation of gas adsorption device 10)
<When adsorbing>
A mixed gas containing an adsorbent (carbon dioxide) is introduced into the adsorption container 12 from a mixed gas supply source through the upper port 13a, and is led out from the lower port 13b. At this time, the adsorbent is adsorbed by the adsorbent 16. Thereafter, the gas from which the adsorbed substance has been removed is supplied to the supply destination from the lower port 13b.

〈脱離時〉
脱離時のガスの流れは、吸着時のガスの流れと同方向である。すなわち、脱離用ガスが脱離用ガス供給源から上部口１３ａを介して吸着容器１２に導入され、下部口１３ｂから導出される。吸着容器１２に導入され、下部口１３ｂから導出される。その際、吸着材１６から吸着物質が脱離される。また、電磁波発生装置１８により吸着容器１２に向けて電磁波を照射し、吸着材１６を誘電加熱することで、脱離効率が促進される。例えば、吸着材１６は、内部温度が１５０～２００℃に加熱される。電磁波の電力は、例えば、１００～２０００ワットである。また、吸着物質が脱離されたガスは、下部口１３ｂから供給先へ供給される。 <At the time of detachment>
The gas flow during desorption is in the same direction as the gas flow during adsorption. That is, the desorption gas is introduced into the adsorption container 12 from the desorption gas supply source through the upper port 13a, and is led out from the lower port 13b. It is introduced into the adsorption container 12 and led out from the lower port 13b. At this time, the adsorbed substance is desorbed from the adsorbent 16. Moreover, the desorption efficiency is promoted by irradiating electromagnetic waves toward the adsorption container 12 by the electromagnetic wave generator 18 and dielectrically heating the adsorbent 16. For example, the adsorbent 16 is heated to an internal temperature of 150 to 200°C. The power of the electromagnetic wave is, for example, 100 to 2000 watts. Further, the gas from which the adsorbed substance has been desorbed is supplied to the supply destination from the lower port 13b.

（実施形態１の作用・効果）
本実施形態によると、吸着物質の脱離時において、電磁波発生装置１８により吸着材１６を誘電加熱した際、吸着容器１２の容器本体１３は誘電加熱されない又は誘電加熱されにくいが、吸着容器１２の温度低下抑制部材１４は誘電加熱される。これにより、温度低下抑制部材１４の熱が吸着容器１２の容器本体１３に奪われるとしても、温度低下抑制部材１４の近傍の吸着材１６の温度の低下を抑制することができる。よって、脱離効率を向上することができる。 (Actions and effects of Embodiment 1)
According to this embodiment, when the adsorbent 16 is dielectrically heated by the electromagnetic wave generator 18 during desorption of the adsorbent, the container body 13 of the adsorption container 12 is not dielectrically heated or is not easily dielectrically heated; The temperature drop suppressing member 14 is dielectrically heated. Thereby, even if the heat of the temperature drop suppressing member 14 is taken away by the container body 13 of the adsorption container 12, a decrease in the temperature of the adsorbent 16 near the temperature drop suppressing member 14 can be suppressed. Therefore, desorption efficiency can be improved.

［実施形態２］
本実施形態は、実施形態１に変更を加えたものであるから、その変更部分について説明し、実施形態１と同一部位については同一符号を付して重複する説明を省略する。図３はガス吸着装置を模式的に示す断面図である。図３に示すように、本実施形態では、実施形態１の温度低下抑制部材１４が、容器本体１３の内側に設けられる容器内壁１５に変更されている。容器内壁１５は、誘電加熱されない材料、容器本体１３と同等の材料、容器本体１３と比べて誘電加熱されにくい材料、容器本体１３と比べて誘電加熱されやすい材料、のいずれの材料で形成してもよい。また、容器内壁１５の材料は、実施形態１（図１参照）の温度低下抑制部材１４と同等の材料、温度低下抑制部材１４と比べて誘電加熱されにくい材料、温度低下抑制部材１４と比べて誘電加熱されやすい材料、のいずれの材料で形成してもよい。 [Embodiment 2]
Since this embodiment is a modification of Embodiment 1, the modified parts will be explained, and the same parts as in Embodiment 1 will be given the same reference numerals and redundant explanation will be omitted. FIG. 3 is a cross-sectional view schematically showing the gas adsorption device. As shown in FIG. 3, in this embodiment, the temperature drop suppressing member 14 of Embodiment 1 is changed to a container inner wall 15 provided inside the container body 13. The inner wall 15 of the container can be made of any of the following materials: a material that is not dielectrically heated, a material that is the same as the container body 13, a material that is less dielectrically heated than the container body 13, and a material that is more easily dielectrically heated than the container body 13. Good too. Further, the material of the inner wall 15 of the container is the same material as the temperature drop suppressing member 14 of Embodiment 1 (see FIG. 1), a material that is less susceptible to dielectric heating than the temperature drop suppressing member 14, and a material that is less likely to be dielectrically heated than the temperature drop suppressing member 14. It may be formed of any material that is easily dielectrically heated.

容器本体１３と容器内壁１５との間には、液体Ｌを貯留可能な円筒状でかつ密閉状の貯留部２０が形成されている。容器本体１３の上端部には、貯留部２０に液体Ｌを注入する注入管２１が配管されている。注入管２１には注入バルブ２２が設けられている。容器本体１３の下端部には、貯留部２０から液体Ｌを排出する排出管２３が配管されている。排出管２３には排出バルブ２４が設けられている。液体Ｌは、例えば、水、メタノール等である。 A cylindrical and sealed storage section 20 capable of storing liquid L is formed between the container body 13 and the container inner wall 15. An injection pipe 21 for injecting the liquid L into the reservoir 20 is installed at the upper end of the container body 13 . The injection pipe 21 is provided with an injection valve 22 . A discharge pipe 23 for discharging the liquid L from the storage section 20 is installed at the lower end of the container body 13 . The discharge pipe 23 is provided with a discharge valve 24 . The liquid L is, for example, water, methanol, or the like.

貯留部２０に液体Ｌを注入する際は、排出バルブ２４を閉じ、注入バルブ２２を開けることで、液体Ｌが液体供給源から注入管２１を介して貯留部２０に注入されて貯留される。貯留部２０に液体Ｌを注入し終えたら注入バルブ２２を閉じる。また、貯留部２０から液体Ｌを排出する際は、排出バルブ２４を開けることで、液体Ｌが貯留部２０から排出管２３を介して所定の排出先に排出される。すなわち、貯留部２０は、液体Ｌを注入及び排出可能になっている。 When injecting the liquid L into the storage section 20, by closing the discharge valve 24 and opening the injection valve 22, the liquid L is injected from the liquid supply source into the storage section 20 via the injection pipe 21 and stored. After injecting the liquid L into the reservoir 20, the injection valve 22 is closed. Furthermore, when discharging the liquid L from the storage section 20, the discharge valve 24 is opened, and the liquid L is discharged from the storage section 20 via the discharge pipe 23 to a predetermined discharge destination. That is, the storage section 20 is capable of injecting and discharging the liquid L.

本実施形態によると、吸着容器１２の貯留部２０に液体Ｌを注入により貯留した状態で、吸着物質の脱離を行う。吸着物質の脱離時において、電磁波発生装置１８により吸着材１６を誘電加熱した際、吸着容器１２の容器本体１３及び容器内壁１５は誘電加熱されない又は誘電加熱されにくいが、液体Ｌは誘電加熱される。これにより、液体Ｌの熱が吸着容器本体１３に奪われるとしても、容器内壁１５の近傍の吸着材１６の温度の低下を抑制することができる。よって、脱離効率を向上することができる。また、吸着物質の脱離後、貯留部２０の液体を排出することにより、吸着容器１２の温度低下を促進し、次回の吸着工程までのリードタイムを短縮することができる。 According to this embodiment, the adsorbed substance is desorbed while the liquid L is injected and stored in the storage section 20 of the adsorption container 12 . When the adsorbent 16 is dielectrically heated by the electromagnetic wave generator 18 during the desorption of the adsorbed substance, the container body 13 and container inner wall 15 of the adsorption container 12 are not dielectrically heated or are not easily dielectrically heated, but the liquid L is dielectrically heated. Ru. Thereby, even if the heat of the liquid L is taken away by the adsorption container main body 13, it is possible to suppress a decrease in the temperature of the adsorbent 16 near the inner wall 15 of the container. Therefore, desorption efficiency can be improved. Further, by discharging the liquid in the storage section 20 after the adsorption substance is desorbed, the temperature of the adsorption container 12 can be reduced, and the lead time until the next adsorption step can be shortened.

FIG. 4 is a cross-sectional view schematically showing the adsorption container. As shown in FIG. 4, the adsorption container 12 includes a cylindrical heat insulating member 26 that covers the outer peripheral surface of the container body 13. The heat insulating member 26 only needs to cover at least a portion of the container body 13. The heat insulating member 26 is made of glass wool or the like that is not easily heated by dielectric.

本実施形態によると、断熱部材２６により吸着容器１２の容器本体１３を保温することができる。 According to this embodiment, the container body 13 of the adsorption container 12 can be kept warm by the heat insulating member 26.
