本発明は汚染物質を含む排ガスの浄化処理や悪臭物質を含む排ガスの脱臭処理などに用いる蓄熱式ガス処理装置に関し、詳しくは（図３、図５、図１１参照）、
蓄熱材５ａを収容した複数の蓄熱室３を設け、燃焼手段７を備える燃焼室６に蓄熱室３それぞれの一端を連通させ、
蓄熱室３への風路を切り替える切換弁体１１を、分配器１０と気室器１３との間にそれら分配器１０と気室器１３とのそれぞれに対する摺接状態で回転させる状態で設け、蓄熱室３それぞれの他端に対し個別に連通させた複数の給排口１６を切換弁体１１の回転方向に並べて分配器１０に形成し、
切換弁体１１の回転に伴い給排口１６に対し順次に対向連通させる被処理ガス用供給口３３と処理済ガス用排出口３５とを、それら被処理ガス用供給口３３と処理済ガス用排出口３５とが同一の給排口１６に対して同時に対向連通しない状態に配置して切換弁体１１に形成し、
気室器１３を介してガス供給路３９を切換弁体１１における被処理ガス用供給口３３に連通させる、又は、気室器１３を介してガス排出路４０を切換弁体１１における処理済ガス用排出口３５に連通させる構成にするとともに、
分配器１０と切換弁体１１との間の隙間を通じての被処理ガス用供給口３３と処理済ガス用排出口３５との連通を遮断する分配器側シール部材１７を、分配器１０と切換弁体１１との間に介装し、気室器１３と切換弁体１１との間の隙間を通じてのガス流出入を阻止する気室器側のシール部材２５を、気室器１３と切換弁体１１との間に介装し、
切換弁体１１の回転に伴い、ガス供給路３９から切換弁体１１に導入される被処理ガスＧを被処理ガス用供給口３３を通じて分配器１０の側へ供給し、かつ、分配器１０の側から処理済ガス用排出口３５を通じて切換弁体１１へ排出される処理済ガスＧ′をガス排出路４０へ導出する構造にしてある蓄熱式ガス処理装置に関する。 The present invention relates to a regenerative gas treatment device used for purification treatment of exhaust gas containing pollutants, deodorization treatment of exhaust gas containing malodorous substances, and the like (see FIGS. 3, 5, and 11).
A plurality of heat storage chambers 3 containing the heat storage material 5a are provided, and one end of each of the heat storage chambers 3 is connected to the combustion chamber 6 provided with the combustion means 7,
A switching valve body 11 for switching the air path to the heat storage chamber 3 is provided between the distributor 10 and the air chamber 13 in a state of rotating in a sliding state with respect to each of the distributor 10 and the air chamber 13, A plurality of supply / discharge ports 16 individually connected to the other ends of the heat storage chambers 3 are arranged in the distributor 10 in the rotation direction of the switching valve body 11,
The treated gas supply port 33 and the treated gas discharge port 35 that are sequentially opposed to and communicated with the supply / exhaust port 16 in accordance with the rotation of the switching valve body 11 include the treated gas supply port 33 and the treated gas supply port. The discharge port 35 is formed in the switching valve body 11 so as not to communicate with the same supply / discharge port 16 at the same time.
The gas supply path 39 is communicated with the gas supply port 33 in the switching valve body 11 via the air chamber 13 or the gas discharge path 40 is connected to the treated gas in the switching valve body 11 via the air chamber 13. In addition to the configuration that communicates with the discharge outlet 35,
A distributor-side seal member 17 that blocks communication between the gas supply port 33 to be processed and the exhaust port for processed gas 35 through the gap between the distributor 10 and the switching valve body 11 is provided with the distributor 10 and the switching valve. A seal member 25 on the air chamber side that is interposed between the air body 11 and prevents gas inflow / outflow through the gap between the air chamber device 13 and the switching valve body 11 is provided with the air chamber device 13 and the switching valve body. 11
Along with the rotation of the switching valve body 11, the gas to be processed G introduced into the switching valve body 11 from the gas supply path 39 is supplied to the distributor 10 through the gas supply port 33, and the distributor 10 The present invention relates to a heat storage type gas processing apparatus having a structure in which a processed gas G ′ discharged from the side through a processed gas discharge port 35 to a switching valve body 11 is led to a gas discharge path 40.

この種の蓄熱式ガス処理装置では（同図３、同図５、同図１１参照）、ガス供給路３９から切換弁体１１に導入される被処理ガスＧを、切換弁体１１の被処理ガス用供給口３３及びそれに対向連通の給排口１６を通じ一部の蓄熱室３に通過させて燃焼室６に至らせ、この燃焼室６において被処理ガスＧ中の汚染物質や悪臭物質などを燃焼により処理している。   In this type of regenerative gas processing apparatus (see FIG. 3, FIG. 5 and FIG. 11), the gas to be processed G introduced into the switching valve body 11 from the gas supply path 39 is treated by the switching valve body 11. The gas supply port 33 and the supply / exhaust port 16 facing each other are passed through a part of the heat storage chamber 3 to reach the combustion chamber 6, where pollutants and malodorous substances in the gas to be treated G are removed. It is processed by combustion.

また、処理済ガスＧ′は他の蓄熱室３に通過させて、その蓄熱室３の収容蓄熱材５ａに対し蓄熱を行わせ、その後、その蓄熱室３に対する給排口１６及びそれに対向連通の処理済ガス用排出口３５を通じ切換弁体１１を通過させて、ガス排出路４０へ導出している。   Further, the treated gas G ′ is passed through the other heat storage chamber 3 to store heat in the stored heat storage material 5a of the heat storage chamber 3, and then the supply / exhaust port 16 for the heat storage chamber 3 and the opposed communication with the heat storage chamber 3 are provided. The switching valve body 11 is passed through the treated gas discharge port 35 and led to the gas discharge path 40.

そして、この処理において切換弁体１１を回転させることで、切換弁体１１の被処理ガス用供給口３３及び処理済ガス用排出口３５のそれぞれを対向連通させる給排口１６を順次に切り換え（すなわち、被処理ガスＧを通過させる蓄熱室３、及び、処理済ガスＧ′を通過させる蓄熱室３を順次に切り換え）、これにより、処理済ガスＧ′の通過をもって先に蓄熱した蓄熱材５ａにより被処理ガスＧを各蓄熱室３の通過過程で予熱するようにして、熱効率の向上を図っている。   Then, by rotating the switching valve body 11 in this process, the supply / exhaust port 16 that makes the treated gas supply port 33 and the processed gas discharge port 35 of the switching valve body 11 communicate with each other is sequentially switched ( That is, the heat storage chamber 3 through which the gas G to be processed and the heat storage chamber 3 through which the processed gas G ′ are passed are sequentially switched), whereby the heat storage material 5a that has previously stored heat with the passage of the processed gas G ′. Thus, the gas G to be treated is preheated in the process of passing through each heat storage chamber 3 to improve the thermal efficiency.

また、この種の蓄熱式ガス処理装置では、分配器１０と切換弁体１１との間の隙間を通じての被処理ガス用供給口３３と処理済ガス用排出口３５との連通を分配器側シール部材１７により遮断することで、分配器１０の側から切換弁体１１の処理済ガス用排出口３５へ排出される処理済ガスＧ′に被処理ガス用供給口通過の被処理ガスＧが混入するのを防止したり、気室器１３と切換弁体１１との間の隙間を通じてのガス流出入を気室器側シール部材２５により阻止することで、切換弁体１１の処理済ガス用排出口３５へ排出される処理済ガスＧ′と被処理ガス用供給口３３から導入された被処理ガスＧとが混合するのを防止したりしている。   Further, in this type of regenerative gas processing apparatus, communication between the gas supply port 33 and the processed gas discharge port 35 through the gap between the distributor 10 and the switching valve body 11 is performed on the distributor side seal. By being blocked by the member 17, the gas to be processed G passing through the supply port for the gas to be processed is mixed into the gas G ′ discharged from the distributor 10 side to the gas outlet 35 for the gas to be processed of the switching valve body 11. The gas flow through the gap between the air chamber unit 13 and the switching valve body 11 is blocked by the air chamber side seal member 25, so that the exhaust gas for the treated gas of the switching valve body 11 is prevented. The treated gas G ′ discharged to the outlet 35 is prevented from mixing with the treated gas G introduced from the treated gas supply port 33.

ところで、従来、分配器側シール部材１７及び気室器側シール部材２５による連通遮断（すなわち、シール）については、スプリングなどの付勢手段により気室器１３を切換弁体１１の側へ付勢することで、切換弁体１１と気室器１３との間の気室器側シール部材２５を気室器１３により押圧して切換弁体１１や気室器１３に対し圧接（気室器側シール部材２５を気室器１３の側に装備する場合では切換弁体１１に対し圧接、気室器側シール部材２５を切換弁体１１の側に装備する場合では気室器１３に対し圧接）させつつ、その気室器１３の付勢により気室器１３を介して切換弁体１１を分配器１０の側へ付勢する形態で、切換弁体１１と分配器１０との間の分配器側シール部材１７を切換弁体１１により押圧して切換弁体１１や分配器１０に対し圧接（分配器側シール部材１７を気室器１３の側に装備する場合では切換弁体１１に対し圧接、分配器側シール部材１７を切換弁体１１の側に装備する場合では気室器１３に対し圧接）させ、これにより、分配器側シール部材１７及び気室器側シール部材２５のそれぞれのシール性を高めるようにしていた。（例えば、下記特許文献１参照）
特開２００５−６１６７５ By the way, conventionally, with regard to communication disconnection (that is, sealing) by the distributor-side seal member 17 and the air chamber-side seal member 25, the air chamber 13 is urged toward the switching valve body 11 by an urging means such as a spring. As a result, the air chamber side seal member 25 between the switching valve body 11 and the air chamber unit 13 is pressed by the air chamber unit 13 and is pressed against the switching valve body 11 and the air chamber unit 13 (air chamber side). When the seal member 25 is provided on the air chamber 13 side, it is pressed against the switching valve body 11, and when the air chamber side seal member 25 is provided on the switch valve body 11 side, it is pressed against the air chamber 13). The distributor between the switching valve body 11 and the distributor 10 is configured such that the switching valve body 11 is biased toward the distributor 10 through the air chamber 13 by the biasing of the air chamber 13. The side seal member 17 is pressed by the switching valve body 11 to switch the switching valve body 11 and the distributor 1. Pressure contact (when the distributor-side seal member 17 is provided on the side of the air chamber 13, it is pressed against the switching valve body 11, and when the distributor-side seal member 17 is provided on the side of the switching valve body 11, the air chamber is Thus, the sealing performance of each of the distributor-side seal member 17 and the air chamber-side seal member 25 is improved. (For example, see Patent Document 1 below)
JP-A-2005-61675

しかし、上記の従来構造では、付勢手段による気室器１３の付勢をもって分配器側シール部材１７と気室器側シール部材２５の両方の押圧圧接を行うことから、分配器側シール部材１７を分配器１０又は切換弁体１１に対して適切な力で圧接させるとともに、気室器側シール部材２５を気室器１３又は切換弁体１１に対して適切な力で圧接させるように、それらシール部材１７、２５のそれぞれに対する付勢力（押圧力）を個別に調整することができず、そのことで、いずれかのシール部材１７，２５のシール性を十分に確保することができなかったり、いずれかのシール部材１７、２５に過度の圧接力が作用してそのシール部材の交換頻度が増加するなどの問題があった。   However, in the above-described conventional structure, the distributor-side seal member 17 and the air-chamber-side seal member 25 are both pressed and pressed by the urging of the air chamber 13 by the urging means. Are pressed against the distributor 10 or the switching valve body 11 with an appropriate force, and the air chamber side seal member 25 is pressed against the air chamber unit 13 or the switching valve body 11 with an appropriate force. The urging force (pressing force) for each of the seal members 17 and 25 cannot be individually adjusted, and as a result, the sealability of any of the seal members 17 and 25 cannot be sufficiently secured, There has been a problem that an excessive pressing force acts on any of the seal members 17 and 25 to increase the replacement frequency of the seal members.

この実情に鑑み、本発明の主たる課題は、合理的な改良をもって上記問題を効果的に解消する点にある。   In view of this situation, the main problem of the present invention is to effectively solve the above problems with a rational improvement.

〔１〕本発明に係る蓄熱式ガス処理装置の第１特徴構成は、
蓄熱材を収容した複数の蓄熱室を設け、燃焼手段を備える燃焼室に前記蓄熱室それぞれの一端を連通させ、
前記蓄熱室への風路を切り替える切換弁体を、分配器と気室器との間にそれら分配器と気室器とのそれぞれに対する摺接状態で回転させる状態で設け、蓄熱室それぞれの他端に対し個別に連通させた複数の給排口を前記切換弁体の回転方向に並べて前記分配器に形成し、
切換弁体の回転に伴い前記給排口に対し順次に対向連通させる被処理ガス用供給口と処理済ガス用排出口とを、それら被処理ガス用供給口と処理済ガス用排出口とが同一の給排口に対して同時に対向連通しない状態に配置して前記切換弁体に形成し、
前記気室器を介してガス供給路を前記切換弁体における前記被処理ガス用供給口に連通させる、又は、前記気室器を介してガス排出路を切換弁体における前記処理済ガス用排出口に連通させる構成にするとともに、
分配器と切換弁体との間の隙間を通じての前記被処理ガス用供給口と前記処理済ガス用排出口との連通を遮断する分配器側シール部材を、前記分配器と前記切換弁体との間に介装し、前記気室器と切換弁体との間の隙間を通じてのガス流出入を阻止する気室器側シール部材を、前記気室器と前記切換弁体との間に介装し、
前記切換弁体の回転に伴い、前記ガス供給路から切換弁体に導入される被処理ガスを前記被処理ガス用供給口を通じて前記分配器の側へ供給し、かつ、分配器の側から前記処理済ガス用排出口を通じて切換弁体へ排出される処理済ガスを前記ガス排出路へ導出する構造において、
前記切換弁体を前記分配器に対する遠近方向での変位が自在な状態に支持するとともに、前記気室器に対しては非作用の状態で前記切換弁体を前記分配器の側へ付勢する切換弁体用付勢手段を設け、
前記気室器を前記切換弁体に対する摺接部と気室器本体とに分割して、その気室器本体に対する前記摺接部の変位が前記切換弁体に対する遠近方向で自在な状態に前記摺接部と前記気室器本体とを伸縮風洞により連結するとともに、前記摺接部を前記切換弁体の側に付勢する摺接部用付勢手段を設けてある点にある。 [1] The first characteristic configuration of the regenerative gas processing apparatus according to the present invention is:
Providing a plurality of heat storage chambers containing the heat storage material, communicating one end of each of the heat storage chambers to a combustion chamber provided with combustion means;
A switching valve body for switching the air path to the heat storage chamber is provided between the distributor and the air chamber device in a state of rotating in a sliding contact state with respect to each of the distributor and the air chamber device. A plurality of supply and discharge ports individually connected to the end are arranged in the distributor in the direction of rotation of the switching valve body,
A treated gas supply port and a treated gas discharge port that are sequentially opposed to and communicated with the supply / exhaust port as the switching valve body rotates, and the treated gas supply port and the treated gas discharge port are connected to each other. It is arranged in the state where it does not communicate with the same supply / discharge port at the same time, and is formed in the switching valve body,
A gas supply path is communicated to the gas supply port in the switching valve body via the air chamber, or a gas discharge path is connected to the treated gas exhaust in the switching valve body via the air chamber. In addition to the configuration to communicate with the exit,
A distributor-side seal member for blocking communication between the treated gas supply port and the treated gas discharge port through a gap between the distributor and the switching valve body, the distributor and the switching valve body; An air chamber side seal member that is interposed between the air chamber device and the switching valve body is interposed between the air chamber device and the switching valve body. Dress
As the switching valve body rotates, the gas to be processed introduced from the gas supply path to the switching valve body is supplied to the distributor side through the gas supply port, and from the distributor side, the gas is supplied. In the structure for deriving the treated gas discharged to the switching valve body through the treated gas discharge port to the gas discharge path,
The switching valve body is supported so as to be freely displaceable in the perspective direction with respect to the distributor, and the switching valve body is biased toward the distributor in a non-acting state with respect to the air chamber. Provide urging means for switching valve body,
The air chamber is divided into a sliding contact portion with respect to the switching valve body and an air chamber main body, and the displacement of the sliding contact portion with respect to the air chamber main body is freely set in a perspective direction with respect to the switching valve body. The sliding contact portion and the air chamber main body are connected by an expansion / contraction wind tunnel, and a sliding contact portion biasing means for biasing the sliding contact portion toward the switching valve body is provided.

つまり、この第１特徴構成によれば、摺接部用付勢手段による気室器摺接部の付勢により、気室器と切換弁体との間の気室器側シール部材を気室器摺接部により押圧して切換弁体や気室器摺接部に対し圧接（気室器側シール部材を気室器の側に装備する場合では切換弁体に対し圧接、気室器側シール部材を切換弁体の側に装備する場合では気室器摺接部に対し圧接）させ、一方、これとは別に気室器に対しては非作用の状態での切換弁体用付勢手段による切換弁体の付勢により、摺接部用付勢手段とは独立させた状態で、分配器と切換弁体との間の分配器側シール部材を切換弁体により押圧して切換弁体や分配器に対し圧接（分配器側シール部材を分配器の側に装備する場合では切換弁体に対し圧接、分配器側シール部材を切換弁体の側に装備する場合では分配器に対し圧接）させるから、分配器側シール部材を分配器又は切換弁体に対して適切な力（例えば、十分な気密性を有しながら耐磨耗性について最も有利となる力）で圧接させ、かつ、気室器側シール部材を気室器又は切換弁体に対して適切な力で圧接させるように、それら分配器側シール部材及び気室器側シール部材のそれぞれに対する付勢力（押圧力）を切換弁体用付勢手段及び摺接部用付勢手段のそれぞれに対する独立的な調整により各別に調整することができる。 That is, according to this first characteristic configuration, the air chamber side seal member between the air chamber and the switching valve body is placed in the air chamber by the biasing of the air chamber sliding contact portion by the sliding contact portion biasing means. Pressed by the instrument sliding contact portion and pressed against the switching valve body and air chamber sliding contact portion (when the air chamber side seal member is equipped on the air chamber side, it is pressed against the switching valve body and the air chamber side. In the case where the seal member is provided on the switching valve body side, it is pressed against the sliding contact portion of the air chamber device, and on the other hand, the switching valve body is energized in a non-acting state with respect to the air chamber device. With the biasing of the switching valve body by the means, the switching-side valve member presses the distributor-side seal member between the distributor and the switching valve body in a state independent of the sliding contact portion biasing means. Pressure contact with the body and distributor (when the distributor side seal member is installed on the distributor side, press contact with the switching valve body, and the distributor side seal member is mounted on the switch valve body side. In this case, the seal member on the distributor side has an appropriate force against the distributor or the switching valve body (for example, it is most advantageous in terms of wear resistance while having sufficient airtightness). is pressed against the force), and, as is pressed against by the appropriate force the air chamber-side seal member against the air chamber device or switch valve body, for each of which the distributor-side seal member and the air chamber-side sealing member The urging force (pressing force) can be adjusted separately by independent adjustment for each of the switching valve body urging means and the sliding contact portion urging means.

また、このように、分配器側シール部材を押圧する為の切換弁体の付勢及び気室器側シール部材を押圧する為の気室器摺接部の付勢を切換弁体用付勢手段と摺接部用付勢手段とにより個別に行うことで、先述の従来構造における付勢手段（すなわち、気室器の付勢をもって分配器側シール部材の押圧と気室器側シール部材の押圧との両方を行う手段）に比べ、それら切換弁体用付勢手段及び摺接部用付勢手段の夫々を小さな付勢力のもので済ませることができ、これにより、それら切換弁体用付勢手段及び摺接部用付勢手段それぞれの微妙な付勢力調整（換言すれば、分配器側シール部材及び気室器側シール部材のそれぞれに対する微妙な押圧力の調整）も容易にすることができる。   Further, the urging of the switching valve body for pressing the distributor side seal member and the urging of the air chamber sliding contact portion for pressing the air chamber side sealing member are thus urged for the switching valve body. And the slidable contact portion urging means separately, the urging means in the above-described conventional structure (that is, with the urging of the air chamber, the distributor side seal member is pressed and the air chamber side seal member is pressed). The switching valve body biasing means and the sliding contact portion biasing means can be made with a small biasing force as compared to the means for performing both of the pressing and the switching valve body mounting force. It is also possible to facilitate the delicate adjustment of the urging force of each of the urging means and the slidable contact portion urging means (in other words, the fine adjustment of the pressing force with respect to each of the distributor side seal member and the air chamber side seal member). it can.

しかも、摺接部用付勢手段については、気室器を気室器本体と摺接部とに分割して、その摺接部のみを付勢するものにするから、不分割の気室器全体を付勢して気室器側シール部材を押圧する構造を採るのに比べ、その必要付勢力をさらに効果的に小さくすることができ、これにより、その微妙な付勢力調整を一層容易にすることができる。   In addition, the slidable contact portion urging means divides the air chamber into the air chamber main body and the slidable contact portion, and urges only the slidable contact portion. Compared to adopting a structure that urges the whole and presses the air chamber side seal member, the required urging force can be reduced more effectively, thereby making it easier to adjust the delicate urging force. can do.

すなわち、これらのことから、先述の従来構造に比べ分配器側シール部材及び気室器側シール部材それぞれのシール性を効果的に高めるとともに、それらシール部材の交換頻度も効果的に低減することができる。   That is, from these, it is possible to effectively improve the sealing performance of the distributor-side seal member and the air chamber-side seal member as compared with the above-described conventional structure, and to effectively reduce the replacement frequency of these seal members. it can.

そしてまた、摺接部用付勢手段の付勢対象を気室器本体とは分割した気室器摺接部のみにして摺接部用付勢手段の付勢力を上述の如く小さくし得る分、装置全体としての付勢構成も先述の従来構造に比べ効果的に小型化することができ、また、その付勢力の影響を受ける装置各部の必要強度も効果的に低減することができ、これにより、装置の小型化及び軽量化、並びに、装置コストの低減も合わせ効果的に達成することができる。   In addition, the urging target of the slidable contact portion urging means can be reduced as described above by limiting the urging target of the slidable contact portion urging means to only the air chamber slidable contact portion divided from the air chamber main body. The urging configuration of the entire device can be effectively reduced in size compared to the conventional structure described above, and the required strength of each part of the device affected by the urging force can be effectively reduced. Accordingly, it is possible to effectively reduce the size and weight of the apparatus and reduce the apparatus cost.

なお、第１特徴構成の実施において、分配器側シール部材は分配器の側に装備する構造、あるいは、切換弁体の側に装備する構造のいずれを採用してもよく、気室器側シール部材についても気室器の側に装備する構造、あるいは、切換弁体の側に装備する構造のいずれを採用してもよい。   In the implementation of the first characteristic configuration, the distributor-side seal member may adopt either a structure equipped on the distributor side or a structure equipped on the switching valve body side. The member may be either a structure equipped on the air chamber side or a structure equipped on the switching valve body side.

また、気室器を介してガス供給路を切換弁体における被処理ガス用供給口に連通させる構造、あるいは、気室器を介してガス排出路を切換弁体における処理済ガス用排出口に連通させる構造のいずれを採ってもよい。   In addition, a structure in which the gas supply path communicates with the supply port for the gas to be processed in the switching valve body through the air chamber, or the gas discharge path through the air chamber to the exhaust port for the processed gas in the switching valve body. Any of the structures for communication may be adopted.

〔２〕本発明の第２特徴構成は、第１特徴構成の実施に好適な実施形態を特定するものであり、その特徴は、
前記気室器本体と前記摺接部との間には、前記切換弁体に対する遠近方向とは直交する方向への前記摺接部の変位を規制する規制手段を設け、
この規制手段は、前記伸縮風洞の内側に位置させる第１補強筒を、前記摺接部の風洞保持体に取り付けるとともに、前記第１補強筒に摺動自在に内嵌させる状態で前記伸縮風洞の内側に位置させる第２補強筒を、前記気室器本体の風洞保持体に取り付けて、これら第１補強筒と第２補強筒との前記直交する方向での接当により、前記直交する方向への前記摺接部の変位を規制する構成にしてある点にある。 [2] The second characteristic configuration of the present invention specifies an embodiment suitable for the implementation of the first characteristic configuration.
Between the air chamber main body and the sliding contact portion, there is provided a restricting means for restricting displacement of the sliding contact portion in a direction orthogonal to the perspective direction with respect to the switching valve body,
The restricting means attaches the first reinforcing cylinder positioned inside the telescopic wind tunnel to the wind tunnel holding body of the sliding contact portion, and slidably fits the first reinforcing cylinder in the first reinforcing cylinder. A second reinforcing cylinder positioned on the inner side is attached to the air channel holder of the air chamber main body, and the first reinforcing cylinder and the second reinforcing cylinder are contacted in the orthogonal direction in the orthogonal direction. The displacement of the sliding contact portion is restricted .

つまり、この第２特徴構成によれば、切換弁体に対する遠近方向とは直交する方向での気室器本体と摺接部との相対変位が上記規制手段により規制されるから、摺接部を気室器本体に連結する伸縮風洞体の形成材に布やシートなどの柔軟な可撓性材料を採用することが可能になるなど、その伸縮風洞体の材質・構造の選択幅を広くすることができ、これにより、装置の軽量化や装置コストの低廉化などを一層促進することが可能となる。 That is, according to the second characteristic configuration, the relative displacement between the air chamber main body and the sliding contact portion in the direction orthogonal to the perspective direction with respect to the switching valve body is restricted by the restriction means. To widen the selection range of materials and structures of the telescopic wind tunnel body, such as a flexible flexible material such as cloth or sheet can be used as the material for the telescopic wind tunnel body connected to the air chamber body.

Providing a plurality of heat storage chambers containing the heat storage material, communicating one end of each of the heat storage chambers to a combustion chamber provided with combustion means;
A switching valve body for switching the air path to the heat storage chamber is provided between the distributor and the air chamber device in a state of rotating in a sliding contact state with respect to each of the distributor and the air chamber device. A plurality of supply and discharge ports individually connected to the end are arranged in the distributor in the direction of rotation of the switching valve body,
A treated gas supply port and a treated gas discharge port that are sequentially opposed to and communicated with the supply / exhaust port as the switching valve body rotates, and the treated gas supply port and the treated gas discharge port are connected to each other. It is arranged in the state where it does not communicate with the same supply / discharge port at the same time, and is formed in the switching valve body,
A gas supply path is communicated to the gas supply port in the switching valve body via the air chamber, or a gas discharge path is connected to the treated gas exhaust in the switching valve body via the air chamber. In addition to the configuration to communicate with the exit,

Dress
As the switching valve body rotates, the gas to be processed introduced from the gas supply path to the switching valve body is supplied to the distributor side through the gas supply port, and from the distributor side, the gas is supplied. In the structure for deriving the treated gas discharged to the switching valve body through the treated gas discharge port to the gas discharge path,
The switching valve body is supported so as to be freely displaceable in the perspective direction with respect to the air chamber device, and the switching valve body is biased toward the air chamber device in a non-acting state with respect to the distributor. An urging means for the switching valve body is provided,
The distributor is divided into a sliding contact portion with respect to the switching valve body and a distributor main body, and the displacement of the sliding contact portion with respect to the distributor main body is free in a perspective direction with respect to the switching valve body. And a distributor main body are connected by a telescopic wind tunnel body, and a slidable contact portion urging means for urging the slidable contact portion toward the switching valve body is provided. In the point.

つまり、この第６特徴構成によれば、摺接部用付勢手段による分配器摺接部の付勢により、分配器と切換弁体との間の分配器側シール部材を分配器摺接部により押圧して切換弁体や分配器摺接部に対し圧接（分配器側シール部材を分配器の側に装備する場合では切換弁体に対し圧接、分配器側シール部材を切換弁体の側に装備する場合では分配器に対し圧接）させ、
一方、これとは別に分配器に対しては非作用の状態での切換弁体用付勢手段による切換弁体の付勢により、摺接部用付勢手段とは独立させた状態で、気室器と切換弁体との間の気室器側シール部材を切換弁体により押圧して切換弁体や気室器に対し圧接（気室器側シール部材を気室器の側に装備する場合では切換弁体に対し圧接、気室器側シール部材を切換弁体の側に装備する場合では気室器に対し圧接）させるから、分配器側シール部材を分配器又は切換弁体に対して適切な力（例えば、十分な気密性を有しながら耐磨耗性について最も有利となる力）で圧接させ、かつ、気室器側シール部材を気室器又は切換弁体に対して適切な力で圧接させるように、それら分配器側シール部材及び気室器側シール部材のそれぞれに対する付勢力（押圧力）を切換弁体用付勢手段及び摺接部用付勢手段のそれぞれに対する独立的な調整により各別に調整することができる。 In other words, according to the sixth characteristic configuration, the distributor-side seal member between the distributor and the switching valve body is moved by the biasing of the distributor sliding contact portion by the sliding contact portion biasing means. Pressing against the switching valve body and the sliding portion of the distributor (if the distributor-side seal member is installed on the distributor side, press against the switching valve body and place the distributor-side seal member on the switching valve body side. In the case of equip with the distributor)
On the other hand, with the biasing of the switching valve body by the switching valve body biasing means in a non-acting state with respect to the distributor, the air flow is made independent of the sliding contact portion biasing means. The air chamber side seal member between the air chamber and the switching valve body is pressed by the switching valve body and pressed against the switching valve body or air chamber (the air chamber side sealing member is provided on the air chamber side. In this case, the pressure regulator is pressed against the switching valve body, and when the air chamber container side seal member is provided on the switching valve body side, the distributor side seal member is pressed against the distributor or the switching valve body. Pressure-contact with an appropriate force (for example, a force that is most advantageous in terms of wear resistance while having sufficient air tightness), and the air chamber side sealing member is appropriate for the air chamber device or the switching valve body. so as to press-contact with a force, the biasing force against their respective distributor-side seal member and the air chamber-side seal member (pressing ) Can be adjusted to each other by independent adjustment for each of the switching valve-body urging means and the sliding contact portion for biasing means.

また、このように、気室器側シール部材を押圧する為の切換弁体の付勢及び分配器側シール部材を押圧する為の分配器摺接部の付勢を切換弁体用付勢手段と摺接部用付勢手段とにより個別に行うことで、先述の従来構造における付勢手段（すなわち、気室器の付勢をもって分配器側シール部材の押圧と気室器側シール部材の押圧との両方を行う手段）に比べ、それら切換弁体用付勢手段及び摺接部用付勢手段の夫々を小さな付勢力のもので済ませることができ、これにより、それら切換弁体用付勢手段及び摺接部用付勢手段それぞれの微妙な付勢力調整（換言すれば、分配器側シール部材及び気室器側シール部材のそれぞれに対する微妙な押圧力の調整）も容易にすることができる。   Further, the urging means for the switching valve body for urging the switching valve body for pressing the air chamber side seal member and the urging of the distributor sliding contact portion for pressing the distributor side seal member in this way And the slidable contact portion urging means separately, the urging means in the above-described conventional structure (that is, pressing the distributor side seal member and the air chamber side seal member with the urging force of the air chamber) The switching valve body biasing means and the sliding contact portion biasing means can be completed with a small biasing force, thereby enabling the switching valve body biasing force. Subtle urging force adjustment of each of the urging means and the sliding contact portion urging means (in other words, fine adjustment of the pressing force with respect to each of the distributor side seal member and the air chamber side seal member) can be facilitated. .

しかも、摺接部用付勢手段については、分配器を分配器本体と摺接部とに分割して、その摺接部のみを付勢するものにするから、不分割の分配器全体を付勢して分配器側シール部材を押圧する構造を採るのに比べ、その必要付勢力をさらに効果的に小さくすることができ、これにより、その微妙な付勢力調整を一層容易にすることができる。   In addition, the slidable contact portion urging means divides the distributor into the distributor main body and the slidable contact portion and urges only the slidable contact portion. Compared with the structure in which the distributor-side seal member is pressed, the required urging force can be further effectively reduced, and the delicate urging force adjustment can be further facilitated. .

すなわち、これらのことから、先述の従来構造に比べ分配器側シール部材及び気室器側シール部材それぞれのシール性を効果的に高めるとともに、それらシール部材の交換頻度も効果的に低減することができる。   That is, from these, it is possible to effectively improve the sealing performance of the distributor-side seal member and the air chamber-side seal member as compared with the above-described conventional structure, and to effectively reduce the replacement frequency of these seal members. it can.

そしてまた、摺接部用付勢手段の付勢対象を分配器本体とは分割した分配器摺接部のみにして摺接部用付勢手段の付勢力を上述の如く小さくし得る分、装置全体としての付勢構成も先述の従来構造に比べ効果的に小型化することができ、また、その付勢力の影響を受ける装置各部の必要強度も効果的に低減することができ、これにより、装置の小型化及び軽量化、並びに、装置コストの低減も合わせ効果的に達成することができる。   In addition, the apparatus can reduce the urging force of the slidable portion urging means as described above by limiting the urging target of the slidable portion urging means to only the distributor slidable portion divided from the distributor main body. The overall biasing configuration can also be effectively reduced in size compared to the above-described conventional structure, and the required strength of each part of the device affected by the biasing force can be effectively reduced. A reduction in the size and weight of the apparatus and a reduction in the apparatus cost can also be achieved effectively.

As for the seal member, either a structure equipped on the distributor side or a structure equipped on the switching valve body side may be adopted.

また、気室器を介してガス供給路を切換弁体における被処理ガス用供給口に連通させる構造、あるいは、気室器を介してガス排出路を切換弁体における処理済ガス用排出口に連通させる構造のいずれを採ってもよい。   In addition, a structure in which the gas supply path communicates with the supply port for the gas to be processed in the switching valve body through the air chamber, or the gas discharge path through the air chamber to the exhaust port for the processed gas in the switching valve body. Any of the structures for communication may be adopted.

At the inside of the telescopic wind tunnel, a slidable contact portion-side reinforcing cylinder positioned on the inside of the sliding contact portion is attached to a wind tunnel holder of the slidable contact portion and is slidably fitted in the sliding contact portion-side reinforcing tube. The distributor-side reinforcing cylinder to be positioned is attached to the wind tunnel holding body of the distributor main body, and by the contact in the orthogonal direction between the sliding cylinder-side reinforcing cylinder and the distributor-side reinforcing cylinder, The displacement of the sliding contact portion in the orthogonal direction is restricted.

A partition is formed by an intermediate bottom plate 26e and an upper vertical partition wall 26d formed at a location adjacent to the partition wall 26b. Reference numeral 32 denotes a reinforcing rib plate having a communication port 32a for indoor communication.

なお、螺旋状の仕切中床２６ｃを用いて切換弁体１１の内部を供給室２７と排出室２８とに区画することで、弁底壁２３の気室器用連通口３７の開口面積を広く確保して排出効率を高く確保しながらも弁体高さの短縮化を図ってある。   In addition, the opening area of the communication port 37 for the air chamber device of the valve bottom wall 23 is ensured widely by dividing the inside of the switching valve body 11 into the supply chamber 27 and the discharge chamber 28 using the spiral partitioning inner floor 26c. Thus, the height of the valve body is shortened while ensuring high discharge efficiency.

そして、この構成において、被処理ガスＧを供給するガス供給路３９を弁体器１２内の器内空間１２Ａに接続し、一方、気室器１３から処理済ガスＧ′を排出するガス排出路４０を弁体器１２内に形成の気室器１３に接続してある。   In this configuration, the gas supply path 39 for supplying the gas G to be processed is connected to the internal space 12A in the valve body 12, while the gas discharge path for discharging the processed gas G 'from the air chamber 13 is provided. 40 is connected to the air chamber 13 formed in the valve body 12.

つまり、この蓄熱式ガス処理装置では、図３に示すように、ガス供給路３９から弁体器１２内における切換弁体１１及び気室器１３周りの器内空間１２Ａ及び切換弁体１１の弁周壁２１に形成の弁体器用連通口３８を通じて切換弁体１１の供給室２７に導入される被処理ガスＧ（例えば、有機溶剤を含む塗装ブースからの排出空気）を、切換弁体１１の弁天板２２に形成の被処理ガス供給口３３、その被処理ガス供給口３３に対向連通する分配器１０側の給排口１６、その給排口１６に連通の給排室８、及び、その給排室８に連通の給排路１５を通じ、一部の蓄熱室３に通過させて燃焼室６に至らせ、この燃焼室６において被処理ガスＧ中の汚染物質や悪臭物質などを燃焼により処理する。   That is, in this heat storage type gas processing apparatus, as shown in FIG. 3, the valve 12 in the valve body 12 and the internal space 12 </ b> A around the air chamber 13 and the valve of the switch valve body 11 from the gas supply path 39. A gas to be treated G (for example, exhaust air from a painting booth containing an organic solvent) introduced into the supply chamber 27 of the switching valve body 11 through the valve body communication port 38 formed in the peripheral wall 21 is supplied to the valve body of the switching valve body 11. A gas supply port 33 formed in the plate 22, a supply / discharge port 16 on the distributor 10 side that communicates with the gas supply port 33, a supply / discharge chamber 8 that communicates with the supply / discharge port 16, and its supply Through a supply / exhaust passage 15 communicating with the exhaust chamber 8, it passes through a part of the heat storage chamber 3 to reach the combustion chamber 6, and in this combustion chamber 6, the pollutants and odorous substances in the gas G to be treated are treated by combustion. To do.

また、処理済ガスＧ′は、燃焼室６から他の蓄熱室３に通過させて、その蓄熱室３に収容の蓄熱材５ａに対し蓄熱を行わせ、その後、その蓄熱室３に連通の給排路１５、その給排路１５に連通する分配器１０側の給排室８、その給排室８に連通の給排口１６、及び、その給排口１６に対向連通する切換弁体１１側の処理済ガス用排出口３５を通じ、切換弁体１１の排出室２８へ導くとともに、それに続き、気室器用連通口３７及び気室器１３を通じて、ガス排出路４０へ導出する。   Further, the treated gas G ′ is passed from the combustion chamber 6 to the other heat storage chamber 3 to store heat in the heat storage material 5 a accommodated in the heat storage chamber 3, and thereafter, the heat storage chamber 3 is connected to the heat storage chamber 3. A discharge path 15, a supply / discharge chamber 8 on the distributor 10 side communicating with the supply / discharge path 15, a supply / discharge port 16 communicating with the supply / discharge chamber 8, and a switching valve body 11 communicating oppositely with the supply / discharge port 16. Then, the gas is led to the discharge chamber 28 of the switching valve body 11 through the processed gas discharge port 35 on the side, and subsequently led out to the gas discharge path 40 through the air chamber communication port 37 and the air chamber 13.

さらに、図４に示すように、処理済ガスＧ′の一部は、パージ用ガスＧ″として燃焼室６から更に他の蓄熱室３に通過させて、その後、その蓄熱室３に連通の給排路１５、その給排路１５に連通する分配器１０側の給排室８、その給排室に連通の給排口１６、及び、その給排口１６に対向連通する切換弁体１１の弁天板２２に形成のパージ用口３４を通じ、切換弁体１１のパージ用室３１へ導くとともに、それに続き、切換弁体１１の筒状回転軸２４に形成のパージ用連通口３６、筒状回転軸２４の内部、筒状回転軸２４の上端部に形成の連通孔２４ａ、連通孔２４ａに連通させた分配器１０の中央室１８、中央室１８に接続のパージ用ガス排出路２０を通じ、被処理ガスＧに合流させる。   Further, as shown in FIG. 4, a part of the treated gas G ′ is passed as a purge gas G ″ from the combustion chamber 6 to the other heat storage chamber 3, and thereafter, the heat storage chamber 3 is continuously connected to the supply gas. The discharge path 15, the supply / discharge chamber 8 on the distributor 10 side that communicates with the supply / discharge path 15, the supply / discharge port 16 that communicates with the supply / discharge chamber, and the switching valve body 11 that communicates with the supply / discharge port 16 oppositely. The purge port 34 formed in the valve top plate 22 is led to the purge chamber 31 of the switching valve body 11, and subsequently, the purge communication port 36 formed in the cylindrical rotating shaft 24 of the switching valve body 11, the cylindrical rotation Through the inside of the shaft 24, a communication hole 24a formed at the upper end of the cylindrical rotating shaft 24, the central chamber 18 of the distributor 10 communicated with the communication hole 24a, and the purge gas discharge passage 20 connected to the central chamber 18 Merge with the processing gas G.

そして、この処理において切換弁体１１を回転させることで、切換弁体１１の弁天板２２に形成の供給口３３、パージ用口３４、排出口３５の各々を対向連通させる分配器１０側の給排口１６を順次に切り換えて、この切り換えにより、被処理ガスＧを通過させる蓄熱室３、パージ用ガスＧ″を通過させる蓄熱室３、処理済ガスＧ′を通過させる蓄熱室３を順次に切り換える形態で、各蓄熱室３を被処理ガスＧの通過状態、パージ用ガスＧ″の通過状態、処理済ガスＧ′の通過状態に、その順で順次に切り換え、これにより、処理済ガスＧ′の通過をもって先に蓄熱した蓄熱材５ａにより被処理ガスＧを各蓄熱室３の通過過程において予熱する。   Then, by rotating the switching valve body 11 in this process, the supply port 33, the purge port 34, and the discharge port 35 formed on the valve top plate 22 of the switching valve body 11 are connected to each other so as to face each other. By switching the exhaust port 16 in order, the heat storage chamber 3 through which the gas G to be processed passes, the heat storage chamber 3 through which the purge gas G ″ passes, and the heat storage chamber 3 through which the treated gas G ′ passes are sequentially switched. In the form of switching, each heat storage chamber 3 is sequentially switched to the passage state of the gas to be treated G, the passage state of the purge gas G ″, and the passage state of the treated gas G ′ in this order. The gas to be treated G is preheated in the process of passing through each heat storage chamber 3 by the heat storage material 5a that has previously stored heat by passing '.

また、被処理ガスＧの通過後、次に処理済ガスＧ′を通過させるに先立ち各蓄熱室３にパージ用ガスＧ″（処理済みガスＧ′の一部）を通過させるようにし、これにより、蓄熱室３内に残る被処理ガスＧを次の処理済ガスＧ′の通過の前に燃焼室６へ排出して、次にその蓄熱室３を通過する処理済ガスＧ′に残留被処理ガスＧが混入することを防止する。   In addition, after passing the gas to be processed G, the purging gas G ″ (a part of the processed gas G ′) is allowed to pass through each heat storage chamber 3 before passing the processed gas G ′ next. The gas to be processed G remaining in the heat storage chamber 3 is discharged to the combustion chamber 6 before passing the next processed gas G ′, and then the gas to be processed G ′ passing through the heat storage chamber 3 is left to be processed. The gas G is prevented from being mixed.

前記弁体器１２下方の設置架台１４には、連結回転軸４１を介して弁体器１２に内装の切換弁体１１の筒状回転軸２４を回転させる駆動ユニット４２を脱着自在に配設してあり、この駆動ユニット４２は、連結回転軸４１の下端に脱着自在にフランジ接続される駆動回転軸４３と、軸受４４ａを介して駆動回転軸４３を下方から上下動自在に気体（本例では空気）の圧力で支持する切換弁体用付勢手段としてのエアバネ機構４４と、駆動回転軸４３に配設したギア４３ａとの噛合接続により駆動回転軸４３を回転させる減速機付きモータ４５とを、設置架台１４に対しボルト等で脱着自在に取り付けられるフレーム枠４８に組み付けて構成してある。   On the installation base 14 below the valve body 12, a drive unit 42 for rotating the cylindrical rotary shaft 24 of the internal switching valve body 11 to the valve body 12 via a connecting rotary shaft 41 is detachably disposed. The drive unit 42 includes a drive rotary shaft 43 that is detachably flanged to the lower end of the coupling rotary shaft 41, and a gas (in this example) that allows the drive rotary shaft 43 to move up and down from below via a bearing 44a. An air spring mechanism 44 as an urging means for the switching valve body that is supported by the pressure of the air), and a motor 45 with a speed reducer that rotates the drive rotary shaft 43 by meshing connection with a gear 43a disposed on the drive rotary shaft 43. The frame is attached to a frame 48 that is detachably attached to the installation base 14 with bolts or the like.

A lower bearing 47 provided with a seal member for preventing the treated gas G ′ from leaking to the outside through the gap is provided, whereby the cylindrical rotating shaft 24 and the connecting rotating shaft 41 are connected to each other. The connected switching valve body 11 is configured to freely move in the direction of the axis P of the rotation axis X.

つまり、駆動ユニット４２の減速機付きモータ４５による回転力を駆動回転軸４３により切換弁体１１の回転軸Ｘに伝達して、切換弁体１１を弁体器１２内において縦軸芯Ｐ周りで図中矢印Ｒで示す方向に回転させながら、駆動ユニット４２のエアバネ機構４４による押圧力を駆動回転軸４３を介して切換弁体１１の回転軸Ｘに伝達して、これにより、エアバネ機構４４の押圧付勢力が気室器１３に対しては非作用の状態で、切換弁体１１を分配器１０に対する遠近方向（本例では、上下方向）での変位を自在に分配器１０の側へ付勢する。   That is, the rotational force of the motor 45 with a speed reducer of the drive unit 42 is transmitted to the rotation axis X of the switching valve body 11 by the drive rotation shaft 43, and the switching valve body 11 is moved around the vertical axis P in the valve body 12. While rotating in the direction indicated by the arrow R in the figure, the pressing force by the air spring mechanism 44 of the drive unit 42 is transmitted to the rotation axis X of the switching valve body 11 via the drive rotation shaft 43, thereby With the pressing biasing force not acting on the air chamber 13, the switching valve body 11 can be freely displaced toward the distributor 10 in the perspective direction (vertical direction in this example) with respect to the distributor 10.

The portion 53 and the air chamber main body 52 are connected in an airtight state or in a state of being kept substantially airtight).

また、気室器１３には、摺接部５３を切換弁体１１の側に付勢する摺接部用付勢手段としてのスプリングユニット５１の複数個（本例では４個）を、摺接部５３の周りにおいて等間隔に配置する状態で組み付け装備（詳しくは、気室器本体５２と摺接部５３との間に亘らせた状態に組み付け装備）してある。   In addition, a plurality of spring units 51 (four in this example) as sliding contact portion biasing means for biasing the sliding contact portion 53 toward the switching valve body 11 are slidably contacted with the air chamber 13. Assembling equipment (specifically, assembling equipment in a state extending between the air chamber main body 52 and the sliding contact portion 53) is arranged around the portion 53 at equal intervals.

図７〜図１０に示すように、前記摺接部５３の下端に接続された略円筒状の上側風洞保持体５６の外周面には、伸縮風洞固定ボルト（図示しない）を取り付けるための取付孔５６ａを周方向等間隔で多数形成してあり、また、気室器本体５２の上方開口縁部に下端が接続された略円筒状の下側風洞保持体５４の外周面には、伸縮風洞固定ボルト（図示しない）を取り付けるための取付孔５４ａを周方向等間隔で多数形成してある。   As shown in FIGS. 7 to 10, a mounting hole for attaching a telescopic wind tunnel fixing bolt (not shown) to the outer peripheral surface of the substantially cylindrical upper wind tunnel holder 56 connected to the lower end of the sliding contact portion 53. A large number of 56a are formed at equal intervals in the circumferential direction, and a telescopic wind tunnel is fixed to the outer peripheral surface of the substantially cylindrical lower wind tunnel holding body 54 whose lower end is connected to the upper opening edge of the air chamber main body 52. A large number of mounting holes 54a for mounting bolts (not shown) are formed at equal intervals in the circumferential direction.

そして、摺接部５３の上側風洞保持体５６と気室器本体５２の下側風洞保持体５４との夫々に伸縮風洞５５の上下両端部の各々を伸縮風洞固定ボルトにて固定することで、伸縮風洞５５の可撓性によって伸縮風洞５５の高さ範囲内（換言すれば、軸芯Ｐ方向の長さ範囲内）で、気室器本体５２に対し摺接部５３を切換弁体１１に対する遠近方向（本例では、上下方向）に変位自在に構成してある。   Then, by fixing each of the upper and lower end portions of the telescopic wind tunnel 55 to the upper wind tunnel holding body 56 of the sliding contact portion 53 and the lower wind tunnel holding body 54 of the air chamber main body 52 with the telescopic wind tunnel fixing bolts, Due to the flexibility of the telescopic wind tunnel 55, the slidable contact portion 53 with respect to the air chamber body 52 with respect to the switching valve body 11 is within the height range of the telescopic wind tunnel 55 (in other words, within the length range in the axis P direction). It is configured to be displaceable in the perspective direction (in this example, the vertical direction).

５７Ａは、摺接部５３の上側風洞保持体５６に対し伸縮風洞５５の内側に位置する状態で伸縮風洞５５の上端部とともに伸縮風洞固定ボルトにて取り付けた金属製の第１補強筒であり、５７Ｂは、第１補強筒５７Ａに内嵌状態で摺動可能な外径で構成され、気室器本体５２の下側風洞保持体５４に対し伸縮風洞５５の内側に位置する状態で伸縮風洞５５の下端部とともに伸縮風洞固定ボルトにて取り付けた金属製の第２補強筒である。   57A is a metal first reinforcing cylinder attached to the upper wind tunnel holding body 56 of the sliding contact portion 53 with the telescopic wind tunnel fixing bolt together with the upper end portion of the telescopic wind tunnel 55 in a state of being located inside the telescopic wind tunnel 55. 57B has an outer diameter that is slidable in the first reinforcing cylinder 57A while being fitted in the first reinforcing cylinder 57A, and the telescopic wind tunnel 55 is located inside the telescopic wind tunnel 55 with respect to the lower wind tunnel holding body 54 of the air chamber body 52.

By urging the switching valve body 11 toward the distributor 10 with no urging force acting on the air chamber 13 by the air spring mechanism 44, the sliding contact portion biasing means and the switching valve body mounting By independent adjustment of each of the biasing means, the biasing force to the sliding contact portion 53 for pressing the air chamber side seal member 25 and the switching valve body 11 for pressing the distributor side seal member 17 are pressed. The power can be adjusted separately.

そして、摺接部５３及び切換弁体１１に対する付勢力の個別調整により、気室器１３と切換弁体１１との間において、気室器１３の上端開口縁部（詳しくは、摺接部５３の上端開口縁部）に装備の気室器側シール部材２５を摺接部５３により押圧させる形態で切換弁体１１の弁底板２３に対し適切な力で確実に圧接させて、気室器１３と切換弁体１１との間を通じて弁体器１２の器内空間１２Ａと気室器１３及び切換弁体１１内との連通を防止し、この連通防止により、器内空間１２Ａ内の被処理ガスＧと気室器１３内の処理済ガスＧ′との混合を効果的且つ確実に防止するとともに、分配器１０と切換弁体１１との間において、分配器１０の底板１０ａに装備の分配器側シール部材１７を切換弁体１１により押圧させる形態で切換弁体１１の弁天板２２に対し適切な力で確実に圧接させて、分配器１０の底板１０ａと切換弁体１１の弁天板２２との間の隙間を通じての被処理ガス供給口３３、処理済ガス排出口３５、パージ用口３４の相互の連通を弁天板２２に対する分配器側シール部材１７の摺接により遮断し、その隙間連通による処理済ガスＧ′中への被処理ガスＧの混入を効果的且つ確実に防止するようにしてある。   Then, by individually adjusting the urging force with respect to the sliding contact portion 53 and the switching valve body 11, an upper end opening edge of the air chamber device 13 (specifically, the sliding contact portion 53 between the air chamber device 13 and the switching valve body 11). The air chamber unit side seal member 25 is pressed against the valve bottom plate 23 of the switching valve body 11 with an appropriate force in such a manner that the air chamber unit side sealing member 25 is pressed by the sliding contact portion 53 to the air chamber unit 13. Between the internal space 12A of the valve body 12 and the air chamber 13 and the switching valve body 11 is prevented between the switch valve body 11 and the switching valve body 11, and the gas to be treated in the internal space 12A is prevented by this communication prevention. G and the treated gas G ′ in the air chamber 13 are effectively and reliably prevented from mixing, and the distributor provided on the bottom plate 10 a of the distributor 10 is between the distributor 10 and the switching valve body 11. The switching valve body 11 is configured such that the side seal member 17 is pressed by the switching valve body 11. A gas supply port 33 to be processed and a processed gas discharge port 35 through a gap between the bottom plate 10a of the distributor 10 and the valve top plate 22 of the switching valve body 11 are securely pressed against the valve top plate 22 with an appropriate force. Further, the mutual communication of the purge port 34 is blocked by the sliding contact of the distributor-side seal member 17 with respect to the valve top plate 22, and mixing of the gas G to be processed into the processed gas G 'due to the clearance communication is effectively and reliably performed. To prevent it.

なお、切換弁体用付勢手段としてのエアバネ機構４４の付勢力により上下動する切換弁体１１の回転軸Ｘと気室器１３との接点（つまり、下部軸受４７）を、設置架台１４に固定された気室器１３の下部（詳しくは、気室器本体５２）に配置してあるから、その下部軸受４７の詰まりや劣化などの経時的な不具合により、下部軸受４７を介して気室器１３に切換弁体用付勢手段の付勢力が若干作用してしまう場合でも、その切換弁体用付勢手段の付勢力を気室器本体５２が受け止めることによって、切換弁体用付勢手段の付勢力が摺接部５３に作用するのを防止することができ、これにより、気室器側シール部材２５の切換弁体１１の弁底板２３に対する適切な圧接力を長期に亘り保持することができる。   The contact point (that is, the lower bearing 47) between the rotary shaft X of the switching valve body 11 that moves up and down by the biasing force of the air spring mechanism 44 as the switching valve body biasing means and the air chamber unit 13 is connected to the installation base 14. Since it is arranged in the lower part of the fixed air chamber 13 (specifically, the air chamber main body 52), due to problems over time such as clogging or deterioration of the lower bearing 47, the air chamber is passed through the lower bearing 47. Even when the urging force of the switching valve body urging means is applied to the chamber 13 slightly, the air chamber main body 52 receives the urging force of the switching valve body urging means, so that the switching valve body urging force is applied. It is possible to prevent the urging force of the means from acting on the sliding contact portion 53, thereby maintaining an appropriate pressure contact force of the air chamber side seal member 25 against the valve bottom plate 23 of the switching valve body 11 over a long period of time. be able to.

また、切換弁体用付勢手段としてのエアバネ機構４４による切換弁体１１に対する付勢向き（具体的には上向き）と、摺接部用付勢手段としてのスプリングユニット５１による摺接部５３に対する付勢向き（具体的には上向き）とを同じ向きに構成してあるから、上記不具合に加えての気室器１３の強度低下などの経時的な不具合により下部軸受４７と気室器１３を介して摺接部５３に切換弁体用付勢手段の付勢力が作用してしまう場合でも、その切換弁体用付勢手段の付勢力によって摺接部用付勢手段による摺接部５３に対する付勢力が相殺低減されるなどの不都合を効果的に回避することができる。   Further, the biasing direction (specifically upward) of the switching valve body 11 by the air spring mechanism 44 as the switching valve body biasing means, and the sliding contact portion 53 by the spring unit 51 as the sliding contact section biasing means. Since the urging direction (specifically upward) is configured in the same direction, the lower bearing 47 and the air chamber 13 are caused to have a problem with time such as a decrease in strength of the air chamber 13 in addition to the above trouble. Even when the urging force of the switching valve body urging means acts on the sliding contact portion 53 via the slidable contact portion 53, the slidable contact portion urging means acts on the sliding contact portion 53 by the urging force of the switching valve body urging means. It is possible to effectively avoid inconveniences such as canceling and reducing the urging force.

そしてまた、被処理ガスＧを供給するガス供給路３９を弁体器１２内の器内空間１２Ａに接続し、処理済ガスＧ′を排出するガス排出路４０を弁体器１２内に形成の気室器１３に接続する構成を採ることで、弁体器１２Ａ内の器内空間１２Ａを高圧下において、そのガス圧により逆向き円錐台状の切換弁体１１に上向きの押し上げ力を作用させるようにして、切換弁体１１を支持する切換弁体用付勢手段の付勢力の低弱化を図ってある。   Further, a gas supply path 39 for supplying the gas G to be processed is connected to the internal space 12A in the valve body 12, and a gas discharge path 40 for discharging the processed gas G 'is formed in the valve body 12. By adopting a configuration connected to the air chamber unit 13, an upward push-up force is applied to the inverted truncated cone-shaped switching valve body 11 by the gas pressure of the internal space 12 </ b> A in the valve body 12 </ b> A under high pressure. In this way, the biasing force of the switching valve body biasing means that supports the switching valve body 11 is reduced.
