Next, a sealing structure and a sealing method of the rotary gas processing apparatus in the first embodiment of the present invention will be described with reference to FIGS. FIG. 1 is a partial cross-sectional view of a seal structure (hereinafter also simply referred to as “seal structure”) of a rotary gas processing apparatus of this example, and FIG. 3 is an exploded perspective view of the seal structure of this example. 2 is an enlarged cross-sectional view of a part of a fixed plate used in the seal structure of this example, and FIG. 4 is an exploded perspective view of a rotor element rotating body used in the seal structure of this example.

  The seal structure 10 has a metal frame 2 attached to the outer peripheral portion of the honeycomb-like rotor element 1 so as to be integrated with the rotor element 1, and a step is formed on the flange-like end face 21 of the metal frame 2 to form an outer ring surface 21a. A fixed plate that causes the inner ring surface 21 b to appear, the end surface 11 of the rotor element 1 and the inner ring surface 21 b of the metal frame 2 to be the same plane, and defines the end surface 11 of the rotor element 1 at least in the adsorption zone 35 and the regeneration zone 33. 3, the annular first seal member 31 that is in sliding contact with the outer ring surface 21 a, and the sliding contact with the inner ring surface 21 b and the end surface 11 of the rotor element 1, and the end surface 11 of the rotor element 1 is defined for each zone. A second seal member 32 is provided.

  In the rotor element rotating body 2A of this example, a metal frame 2 is attached to the outer peripheral portion of the honeycomb-shaped rotor element 1 so as to be integrated with the rotor element 1. As shown in FIG. 4, the honeycomb-like rotor element 1 is a cylindrical object, and a through hole 5 a through which the connecting rod 5 is passed at the center, and the cylindrical object is divided into three in the circumferential direction on both end sides. In addition, three non-penetrating grooves 13 having a predetermined width and a predetermined depth are formed from the end face toward the axial center. In the non-penetrating groove 13, plate-like spokes 25 of the end face side metal frames 22 and 24 are fitted. The non-penetrating groove 13 is not limited to three in this example, and may be four or more. If the number of non-through grooves 13 is two, the cylindrical shape of the end face side metal frames 22 and 24 cannot be maintained and is easily decentered. If the number is too large, the effective processing area in the honeycomb is reduced. The depth (the length in the axial direction) of the non-penetrating groove 13 is that when the end face side metal frames 22 and 24 are attached, the base end portions 26a and 26b of the bosses of the end face side metal frames 22 and 24 are fitted to each other. It is a sufficient dimension. The three-divided area formed by the non-penetrating groove 13 is irrelevant to the zone-divided areas of the adsorption zone and the regeneration zone. The rotor element 1 carries an adsorbent such as zeolite.

  The end face side metal frames 22 and 24 have cylindrical end faces of a flange shape, and are provided with a step in the flange shape, and an annular outer ring surface 21a having a predetermined width and an annular flat surface having a predetermined width. An inner ring surface 21b having a smaller diameter than the outer ring surface 21a appears, and the outer ring surface 21a and the inner ring surface 21b are used as contact surfaces of the seal member. The outer ring surface 21a and the inner ring surface 21b are surfaces perpendicular to the rotation axis direction. In addition, a chamber divided into three equal parts by three plate-like spokes 25 and a boss 26 is formed in the small cylindrical portion 28 having the smallest inner diameter, that is, the inside of the cylindrical main body portion. Friction members 281 are attached to the outer peripheral portion of the small cylindrical portion 28 at a predetermined pitch in the circumferential direction. The friction member 281 improves the engagement with an endless belt wound around this portion. Therefore, the same rubber material as the endless belt can be used.

  The base end side 26a of the boss 26 of the end face side metal frame 24 and the base end side 26b of the boss 26 of the end face side metal frame 22 are fitted together by insertion. That is, the inner diameter of the base end side 26 a of the boss 26 of the end face side metal frame 24 is substantially the same as or slightly larger than the outer diameter of the base end side 26 b of the boss 26 of the end face side metal frame 22. Thereby, the skeleton of the rotor element rotating body 2A can be formed by a simple method. An adhesive may be used for joining the rotor element 1 and the end face side metal frame 24. However, the boundary between the end face 11 of the rotor element 1 and the inner ring surface 21b of the end face side metal frames 22 and 24, and the rotor element. The adhesive is prevented from leaking to the boundary between the end face 11 of 1 and the plate-like spoke 25.

  A cylindrical metal frame 23 </ b> A that is one of the metal frames 2 is attached to the central portion of the outer periphery of the rotor element 1. The cylindrical metal frame 23A is a combination of the semi-cylindrical member 23. The semi-cylindrical member 23 and the end face side metal frames 22 and 24 are screwed using screw holes 231, and the semi-cylindrical member 23 and the rotor element 1 Is preferably adhesive bonding. Thereby, the rotor element 1, the end surface side metal frames 22, 24, and the cylindrical member 23 can be integrated to form the rotor element rotating body 2A. The rotor element rotating body 2A is rotated at a predetermined rotation speed by an endless belt having one end wound around a rotation driving means and the other end wound around the friction member 281 of the end face side metal frame 24.

  The fixed plate 3A is usually fixed to the casing of the rotary gas processing apparatus, defines the end face of the rotor element 1 at least in an adsorption zone and a regeneration zone, and has an annular shape that is in sliding contact with the outer ring surface 21a. The first seal member 31 has a flat surface, the inner ring surface 21b, and the end surface 11 of the rotor element 1, and the second seal member 32 has a flat surface that defines the end surface of the rotor element 1 for each zone. The first seal member 31 and the second seal member 32 may be simply referred to as “seal member”.

  The ring shape of the first seal member 31 may be the same as the ring shape of the outer ring surface 21. That is, the inner diameter of the first seal member 31 is the same as the inner diameter of the outer ring surface 21, and the outer diameter of the first seal member 31 is the same as or larger than the outer diameter of the outer ring surface 21. do it. Thereby, the outer ring | wheel surface 21 can be covered with the 1st sealing member 31, and it can seal completely. Note that the outer peripheral shape of the first seal member 31 is not limited to a circle, and may be a shape other than a circle such as a rectangle. This is because the effect of the first seal member 31 can be obtained if the outer ring surface 21 is covered with the first seal member 31.

  The second seal member 32 has a partition function and a seal function that define the end face of the rotor element 1 for each zone. That is, the side view of the second seal member 32, that is, the shape seen from the direction of the rotation axis, has a circular outer periphery, and a circular hole in the center and a fan-like shape that forms each zone in the circular shape. It has a through hole. Specifically, the zone partition part 321 having a rectangular cross section having a predetermined width that partitions the zones, the large annular part 323 having the same shape as the inner ring part 32 that seals the zone and the outside air, and the small annular part around the center hole 322. The zone partition part 321, the large annular part 323, and the small annular part 322 are flush with each other. The macro annular portion 323 only slides in contact with the inner ring portion 32 and does not slide in contact with the rotor element 1. Thereby, a zone and external air can be sealed reliably.

Width _{w 1} of the zone partition 321 can not be unconditionally determined by the size of the rotor element 1, is generally 10 to 30 mm. If w ₁ is in this range, even if there are large and small irregularities in the rotor element, the inter-zone sealing can be performed reliably. zone between the seal when w ₁ is too small is insufficient, the effective processing area narrowed too large zone is reduced.

Width _{w 2} of the macrocyclic portion 323, is affected to the width of the inner ring portion 32 is the same as the width dimension of the inner ring portion 32 is approximately 10 to 30 mm. If w ₂ is in this range, it is possible to perform the outer seal securely. w ₂ is too small and the outer seal is insufficient, or narrow the too large zone, or the waste is many devices only increases with.

  For example, the fixed plate 3A has a seal portion formed on one surface of a metal plate 3 such as SUS in which a through-hole through which the connecting rod 5 passes is formed in the center. As the seal part, foam metal such as Fluoroflex (registered trademark), silicone foam, etc. are attached to the metal plate 3 side (inner layer part), and a heat-resistant sheet is attached to the sliding contact part side above it. (Sliding contact portion). Fluoroflex is a closed-cell sheet foam made by foaming fluoro rubber, which has excellent heat resistance and compression recovery characteristics, has low degassing components during heating, and is dried in a room where equipment that requires a clean environment is operating. This is suitable for supplying air. As a method for forming the seal member on the metal plate 3, for example, an inner layer portion having a predetermined shape with a step is pasted on the metal plate 3, and then at a position corresponding to the first seal member 31 and the second seal member 32. A method of forming the outer layer portion, or an annular first seal member 31 having a predetermined width and thickness, and a second seal member 32 having a predetermined shape defined in each zone thicker than the first seal member 31 are separately provided. The method of sticking to the metal plate 3 is mentioned.

  The heat-resistant sheet has heat resistance that can withstand temperatures of 200 ° C. or higher, and examples thereof include a PTFE resin sheet. If a heat-resistant sheet is used for the sliding contact portion of the first seal member 31 and the second seal member 32, smooth sliding can be realized at the seal portion even when high-temperature desorption air of 300 ° C. or higher flows in the regeneration zone, Particles generated during sliding can be reduced.

  The first seal member 31 and the second seal member 32 have heat resistance and wear resistance, and have a predetermined hardness. Heat resistance is a characteristic that can sufficiently withstand a use temperature of at least 200 ° C.

  The seal structure 10 according to the present embodiment is formed by fitting a fixing plate 3A at both ends of the rotor element rotating body 2A, and tightening the bolts 6 at both ends through the connecting rod 5 in the central through hole 27 (see FIG. 1 and FIG. 1). (See FIG. 2). The rotor element rotating body 2A and the fixed plate 3A are tightened so that the compressive load is 0.01 to 0.2 MPa. Thereby, smooth rotation and reliable sealing of the rotor element rotating body 2A can be realized.

  The sealing method of the seal structure 10 is a seal between the rotor element rotating body 2A and the fixed plate 3A, and the first seal member 31 formed on the fixed plate 3A and having a flat end surface and the outer ring of the metal frame 2 The end surface 11 of the rotor element 1 formed on the fixed plate 3A is slidably brought into contact with the surface 21a, and the end surface 11 defining the flat surface for each zone is a flat second seal member 32, the inner ring surface 21b, and the end surface 11 of the rotor element 1. Is a sliding contact method.

  According to the sealing structure 10 and the sealing method thereof, a simple structure can be obtained regardless of the presence or absence of large and small irregularities on the end face of the rotor element, and without being affected by the step difference at the joint between the honeycomb structure and the metal frame. Thus, the inter-zone seal and the outer seal can be reliably performed. In particular, since the outer seal is a two-stage seal having different seal positions, the airtightness of the apparatus is further enhanced.

  In addition to the seal structure 10, the rotary gas processing apparatus includes a gas supply means to be processed, a gas supply pipe to be processed, a process gas outlet pipe, a regeneration gas supply pipe, a regeneration gas outlet pipe, a casing, a rotor element rotating body rotating means, and the like. Known equipment is installed. In addition, when the rotary gas processing apparatus of this example is an inert gas dehumidifier, each zone is a dehumidification zone, a regeneration zone, and a cooling zone.

  A rotary gas processing apparatus such as a dehumidifier is used in a known method. That is, the air to be treated supplied from the blower passes through the dehumidifying zone 35, moisture and organic substances are removed, and dry air is obtained from the dehumidifying zone outlet. Further, regeneration air is supplied to the cooling zone 34 to cool the rotor element portion of the zone. In addition, the regeneration air that has exited the cooling zone 34 is heated and then supplied to the regeneration zone 33, and after removing moisture and organic substances from the rotor element portion of the zone, the regeneration air is discharged from the zone.
