Description

ROTARY ADSORPTION / DESORPTION GAS TREATING APPARATUS}

The present invention relates to a gas treating apparatus used for recovery of a solvent contained in a factory exhaust, and more particularly (see FIGS. 1 and 9), which is partitioned by a partition wall K, arranged in the circumferential direction of the rotor, Each of the air passage chambers 7 forms a plurality of air passage chambers 7 in the rotor 2 that extend from one end of the rotor 2 to the other end (one end and the other end in the rotational axis center direction, hereinafter identical). An end wall 27w in which the rotor one end side opening is closed in the air is formed in the air passage 29, and an air vent 29 is formed in the end wall 27w of each air passage chamber 7, and the adsorption layer provided with the air absorbent layer 8 is provided. The air passage chamber 7 mounted on the air vent 29 in a state where the tool 9 is accommodated in each air passage chamber 7 and passing through a predetermined suction position X in the rotation of the rotor 2. Is connected to the rotor chamber from one end side (left side in the drawing) oppositely and features the passage chamber 7 through From the rotor end side to the air passage chamber 7 which passes through the predetermined | prescribed desorption position Y in the uneven gas path 19 of the to-be-processed gas system which makes the gas A ventilate, and the rotor 2 rotated. The ventilating opening 21 of the detachable gas system, which makes the air passage chamber 7 connected in opposition to the ventilating state of the desorbing gas G, is provided, and the air passage chamber 7 faces the air passage chamber 7 from one end of the rotor. The windshields 22a and 22b are placed over the edges of the vents 19 and 21 at the upper and lower sides of the vents 19 and 21 of the gas to be processed and the removable gas system in the rotor rotation direction. Arranging the width W in the rotor rotation direction of the windshield walls 22a and 22b, and one air passage chamber 7 is provided with a vent 19 for a target gas system and a vent for a removable gas system ( Rotating adsorption-and-desorption type gas treatment which is connected to 21) at the same time and prevents passage It relates to the device.

Conventionally, in the rotary adsorption-and-desorption type gas treatment apparatus of the above kind, as shown in Fig. 9, the end wall 27w in which the suction tool mounting vent 29 is formed is placed at one end edge of the rotor of each air passage chamber 7 (i.e. And a position corresponding to the rotor end side edge of each partition wall K), and these end walls 27w are moved in sliding contact with the windscreen walls 22a and 22b in rotation of the rotor 2, respectively. (See Japanese Patent Application Laid-Open No. 6-343814).

More specifically, in the conventional apparatus, the one end edge of each partition wall K is in sliding contact with the windshield walls 22a and 22b in accordance with the rotation of the rotor 2 and the one end edge of the rotor wall K of the partition wall K. A resin sealing member for sealing between the windshields 22a and 22b is provided, thereby further reliably preventing gas leakage between the vent 19 of the gas to be processed and the vent 21 of the removable gas system. From this point of view, the end wall 27w at the rotor end side edge of each air passage chamber 7 is strictly the protruding length of the sealing member from the rotor end side edge of the partition wall K. In the state of adjoining the windshield wall separated from the windshield walls 22a and 22b, the structure moves in sliding contact with the windshield walls 22a and 22b.

However, in the conventional structure (see FIG. 9 above), the windshield walls 22a and 22b slide relative to the end wall 27w of each air passage chamber 7 by the rotation of the rotor 2, and the end wall thereof is moved. From the point of opening and closing of the air vent 29 formed in the 27w, each air vent 29 is opened and closed with respect to the vent 19 of the gas to be processed or the vent 21 of the removable gas system. When it is opened very little from the fully closed state or closed close to the fully closed state (that is, each time the degree of closure of the air vent 29 by the windscreen walls 22a and 22b increases), the suction tool 9 mounted on each vent 29 is provided. A to-be-treated gas A and desorption gas G are unevenly vented with respect to the adsorbent layer 8 of), and therefore, the adsorption performance and desorption performance of each adsorbent layer 8 are sufficiently satisfied. It cannot be exhibited and gas processing performance falls. Moreover, there existed a problem that the degradation of each adsorbent layer 8 progressed locally, and the content period of the adsorbent layer 8 becomes short.

In view of the above circumstances, the main problem of the present invention lies in effectively solving the above problems by rational improvement.

[1] In the first characteristic configuration of the present invention,

Partitioned by partition walls and lined in the circumferential direction of the rotor, each forming a plurality of air passage chambers in the rotor from one end to the other,

In the air passage chambers, end walls in the state of closing the rotor end openings thereof are provided, and vent holes are formed in the end walls of the air passage chambers.

An adsorption tool having a breathable adsorbent layer is mounted to the vents in a state of being accommodated in each air passage chamber,

In the rotation of the rotor, the air passage chamber passing through a predetermined adsorption position is opposed to the air passage chamber from one end side of the rotor, and the air passage chamber of the processing gas system for making the air passage chamber a ventilation state of the processing gas, and the rotation of the rotor. In the air passage chamber passing through the predetermined desorption position in the opposite side of the rotor to form a vent for the removable gas system through which the air passage chamber to ventilate the desorption gas through,

In the air passage chamber, a windscreen wall facing from the rotor end side is disposed over the edges of those vent holes at each of the vent holes of the to-be-processed gas system and the detachable gas system in the rotor rotation direction, respectively.

Rotation type adsorption-and-desorption type gas processing apparatus which makes width of the arrangement | positioning in the rotor rotation direction of the said windscreen wall the width | variety which prevents one air path chamber from being connected to the ventilation opening of the to-be-processed gas simultaneously with the ventilation opening of the detachable gas system at the same time. To

The end wall in each air passage chamber is disposed inside the air passage chamber rather than the rotor end edge of the air passage chamber, and the end wall loses one end of the ventilation guide rotor for opening each air passage chamber to the rotor end side. It is partitioned into the other end side loss of the adsorption tool mounting rotor which is connected to the rotor end side loss through the said vent.

That is, in the above configuration, the closing degree of the rotor one end opening in each air passage room is increased by the relative movement of the windshield wall with respect to the rotor one end opening of each air passage chamber (ie, each air passage chamber). The rotor opening of the rotor is opened from the fully closed state to the slightly closed or close to the totally closed state with respect to the ventilator of the gas to be treated or the vent of the gas to be removed), and is to be treated between each vent and each air passage chamber. Even if deflection occurs due to the narrowing of the gas or the desorption gas, the ventilation guides having a larger volume between the rotor end opening of each air passage chamber facing each vent and the end wall disposed inside each air passage chamber than that. By the presence of the rotor end loss of the rotor, the drift is effectively alleviated by the airflow dispersion and the airflow attenuation in the rotor end loss.

From this point of view, uniform air flow is maintained more stably with respect to the adsorbent layer of each adsorption tool mounted on the vent wall of the end wall in a state where the rotor tartan side is lost from the one end of the rotor. The above-described conventional method of allowing the desorption gas to be ventilated, thereby arranging the end wall forming the suction tool mounting vent at the rotor end side (position corresponding to the rotor end side edge of each partition wall) of each air passage chamber. Compared to the apparatus, the adsorption performance and desorption performance of each adsorbent layer can be exhibited higher and more stable, thereby improving the gas treatment performance, and preventing the local deterioration of each adsorbent layer, thereby prolonging the content period of the adsorbent layer. can do.

[2] In the second characteristic configuration of the present invention, in the implementation of the first characteristic configuration, the contact between the windshield wall and the windshield wall is sealed between the one end edge of the partition wall and the windshield by sliding contact with the windshield wall as the rotor rotates. The resin sealing member made to protrude is protruded from the rotor end side edge of the said partition wall.

That is, according to the above structure, the end wall is disposed inside the air passage chamber more than the one end edge of the rotor of each air passage chamber as described above, so that the distance between the windshield wall and the end wall is sufficiently large (that is, the end wall is separated from the windshield wall). Airtight slide contact with the windshield wall of the resin sealing member to ensure gas leakage between the ventilation path of the gas to be processed and the ventilation hole of the detachable gas system to be secured. As a result, as described above, higher gas treatment performance can be obtained in addition to the uniform ventilation of each adsorbent layer due to the relaxation of the drift.

[3] In the third characteristic configuration of the present invention, in the implementation of the second characteristic configuration, the separation length between the rotor end edge and the end wall of the partition wall protrudes from the rotor end edge of the partition wall. It is made larger than the protruding length of the resin sealing member.

That is, according to the above structure, the end wall is arranged at a position corresponding to the rotor end side edge of the air passage chamber, that is, the rotor end side edge of the partition wall, and the resin sealing member is removed from the rotor end side edge of the partition wall. Compared with the conventional apparatus for protruding, the above-mentioned mitigation action of the drift caused by the loss of one end of the rotor is particularly remarkably exhibited, thereby improving the gas treatment performance and adsorbent layer contents period by the first characteristic configuration. Prolongation of time can be achieved more effectively.

In the rotary adsorption-and-desorption type gas treating apparatus of the above kind, the plane wind speed of the passing gas in each vent of the gas to be treated and the gas to be removed is generally set to about 0.5 to 1.0 m / s, but the plane of the above range In the case of wind speed, the distance between the end edge of the rotor of the partition wall (the position corresponding to the base end of the sealing member in the structure in which the resin sealing member is placed at the end edge of the partition wall) and the end wall should be 40 mm or more. Preferably, the separation length between the front end and the end wall of the resin sealing member is preferably 70 mm or more.

[4] In a fourth characteristic configuration of the present invention, in the implementation of the first to third characteristic configurations, a main wall portion that forms the partition wall by partitioning the rotor other end lost for mounting an adsorption tool. And a dividing structure of an extension wall portion formed by dividing the loss of one end of the rotor for ventilation guide.

That is, according to the above configuration, partition walls for partitioning adjacent air passage chambers in the rotor circumferential direction are formed in the circumferential wall portion and the extension wall portion, which are separate from each other, so as to be located at the boundary between the circumferential wall portion and the extension wall portion. The end wall can be formed by a common wall member that spans a plurality of air passage chambers in the rotor direction, thereby providing a plurality of end walls of the air passage chambers in the rotor circumferential direction as compared to forming the end wall of each air passage chamber as individual partition wall members. Rotor strength can be raised in the state which makes the common wall member for end wall formation which spans the air passage chamber also function effectively as a reinforcement member for rotor shape maintenance.

[5] In the fifth characteristic configuration of the present invention, in the implementation of the first to fourth characteristic configurations, the transmission belt or the electric chain is wound around the outer circumference of the rotor and the motor drive rotating body, and the transmission belt is formed. Or it transmits the rotational force of a motor drive rotation body by an electric chain to a rotor, and makes it the structure which rotates the rotor.

That is, according to the said structure, compared with rotating a rotor by driving and rotating a rotating shaft of a rotor using a gear mechanism etc., the torsional moment acting on a rotor rotating shaft can be made small, and a small diameter of a rotor rotating shaft can be made small. In addition, it is possible to increase the shape retention of the rotor in the state of using the electric belt or the electric chain wound around the outer periphery of the rotor as a reinforcing means, thereby making it possible to reduce the thickness of the rotor forming material, thereby making the device cost low As a result, the weight of the rotor can be reduced to reduce the power required to rotate the rotor.

The outlet 6 is provided with a concentrated gas for sending gas).

As shown in Figs. 1 to 6, the rotor 2 is arranged at the same pitch in the rotor circumferential direction over the entire circumference of the rotor 2 in the state partitioned by the partition wall K, and the rotor 2, respectively. A plurality of air passage chambers 7 (both opening chambers comprising a rotor one end loss 7b and a rotor other end loss 7a to be described later) that extend from one end to the other end, and each air passage room 7 ) Is equipped with a cassette type adsorption tool 9 as shown in FIG. 7, which is detachable and includes a breathable mat-like adsorbent layer 8.

In addition, the inside of the apparatus casing 1 is located on one end side (left side in the drawing) of the rotor 2 by two inner walls 10 and 11 in an arrangement that supports the rotor 2 from both ends. Introduced to-be-processed gas located at the other end side of the rotor arrangement chamber 13 and the rotor 2 between the processed gas chamber 12 and the two inner walls 10 and 11 which are connected and connected to the completion gas outlet 4 It is partitioned into the to-be-processed gas chamber 14 connected to and connected with the sphere 3.

On the inner wall 10 on the side of the processed gas chamber 12, the air passage chamber 7 (the entire opening of one end side thereof is passed through the predetermined suction position X in the rotation of the rotor 2 is the suction position X). Outlet side vent of the to-be-processed gas system which is connected to the air passage chamber 7 within the range of) from the rotor end side to the opposite side, and connects the air passage chamber 7 to the processed gas 12 and passes it therethrough. 19, and an air passage chamber 7 passing through the predetermined detachment position Y in the rotation of the rotor 2 (the air passage chamber in which all of the openings at one end thereof are within the detachment position Y) 7) Desorption gas system for connecting the air passage chamber 7 to the desorption gas inlet 5 through the inner air passage 20 on the inlet side through the rotor body facing away from one end of the rotor. The inlet side vent 21 is formed.

And the said inner wall 10 WHEREIN: The rotor with respect to the exit side vent opening 19 of the gas-processing system of the upper and lower sides of the rotor rotation direction with respect to the inlet side vent port 21 of a detachable gas system, in other words. In each of the upper and lower sides of the rotational direction), a portion that extends between the inlet side vent 21 of the removable gas system and the inlet edge of the outlet side vent 19 of the target gas system is connected to the air passage chamber 7. The windshield walls 22a and 22b facing from one end side are arranged so that the arrangement width W in the rotor rotation direction of these windshields 22a and 22b is one ventilation chamber 7 with both ventilation openings 19 and 21. To prevent passage of gas between both vents (19, 21) by simultaneously connecting to and passing through both vents (19, 21) Width).

On the other hand, the inner wall 11 on the side of the gas chamber 14 to be treated has an air passage that is connected to and passed through the air passage chamber 7 (that is, the processed gas chamber 12) passing through the suction position X. The inlet side vent port 15 of the gas to be processed, which is connected to the chamber 7 from the rotor tartan side oppositely, and connects the air passage chamber 7 to the gas chamber 14 to be processed; The air passage chamber 7 (that is, the air passage chamber 7 in a connection and passage state with respect to the removable gas inlet 5) passing through the position Y is passed through the internal air passage 16 on the delivery side. The outlet side vent port 17 of the detachable gas system connected to the concentrated gas outlet 6 is formed.

In addition, similarly to the other inner wall 10, the inner wall 11 also has the upper and lower sides of the rotor rotational direction with respect to the outlet side vent port 17 of the detachable gas system. The portion between the outlet vent 17 and the inlet edge of the inlet vent 15 of the gas system to be treated is the windshield walls 18a and 18b facing the air passage chamber 7 from the other end of the rotor. Width that prevents the air passage chamber 7 from being connected to both of the ventilation openings 15 and 17 at the same time, that is, the arrangement width W in the rotor rotational direction of the windscreen walls 18a and 18b (ie, Gas leak between both vent holes 15, 17 by one air passage chamber 7 connected to both vent holes 15, 17 at the same time and connected to both vent holes 15, 17 at the same time. Width to prevent).

That is, in the gas processing apparatus, the processing gas A introduced into the processing gas chamber 14 from the processing gas inlet 3 is adsorbed through the inlet side vent 15 of the processing gas system X. Of the cassette-type adsorption tool 9 mounted in the air passage chamber 7 through which the gas to be treated A is passed through the air passage chamber 7 in the air passage chamber. By passing through the mat type adsorbent layer 8, the component to be recovered, such as solvent vapor, in which the gas to be processed A is contained is adsorbed to the constituent adsorbent of the mat type adsorbent layer 8. Then, the treated gas A 'from which the component to be recovered is removed by the adsorption is a processed gas, and the outlet side vent 19 of the target gas system from the air passage chamber 7 at the adsorption position X is used. It flows out into the process gas chamber 12 through the process, and it sends it out from the process gas delivery port 4 outside.

In addition, the desorption gas G (the hot gas having a smaller air volume than the to-be-processed gas A) introduced from the desorption gas inlet 5 in parallel with the adsorption treatment is introduced into the inner air passage chamber 20 and Passes through the air passage chamber 7 in the desorption position Y through the inlet side vent 21 of the desorption gas system, and passes the desorption gas G into the desorption position Y in the passage of the air passage chamber. The number of times the adsorbed adsorbed to the constituent adsorbent of the adsorbent layer 8 at the previous adsorbed position X by passing through the mat-type adsorbent layer 8 of the cassette-type adsorption tool 9 mounted in the air passage chamber 7 The target component is desorbed into the desorption gas (G). The desorption gas G ', which is in a state of containing the recovery target component at a higher concentration than the gas to be processed by this desorption, is concentrated gas from the air passage chamber 7 at the desorption position Y. It flows out to the outlet side vent 17 of a desorption gas system, and is sent out from the concentrated gas discharge port 6 via the discharge side internal air path 16.

Then, the adsorption step and the desorption step are repeated alternately with respect to the adsorption material layer 8 of the cassette type adsorption tool 9 in each air passage chamber 7 as the rotor 2 rotates. The recovery process of the form which transfers the component to collect | recovered in gas A to desorption gas G with less air volume than the to-be-processed gas A, and concentrates is continued.

In the apparatus of the present example, in the rotor 2, a total of 12 air passage chambers 7 are formed in a partition, and the suction position X is slightly smaller than that of 11 air passage chambers. The position having a width (center angle slightly smaller than 330 °), and the detachable position Y is a position having an angular width (center angle slightly smaller than 90 °) that is slightly smaller than three chambers of the air passage chamber 7, The overlapping portion between the suction position X and the desorption position Y is an angle width (center angle slightly smaller than 30 °) that is slightly smaller than that of one chamber of the air passage chamber 7, and the windshield positioned at these overlapping portions The wall portions 18a, 18b, 22a, and 22b have an angular width (central angle slightly larger than 30 °) that is slightly larger than that of one chamber of the air passage chamber 7.

The rotor 2 is based on the inner cylinder 23 and the outer cylinder 24 of concentric arrangement, both ends of the inner cylinder 23 are closed by the closing plates 25a and 25b, and the inner cylinder 23 is These closing plates 25a and 25b are connected to the rotor shaft 26 as a connecting tool.

The annular space between the inner cylinder 23 and the outer cylinder 24 is partitioned into a plurality of partition chambers 7a in which the respective cross-sectional shapes are fan-shaped by partition plates 28 parallel to the same pitch in the rotor circumferential direction. An end wall 27w is formed at one end edge of each compartment 7a by the donut plate-shaped common wall member 27 which closes one end side of the said annular space, and is provided at the end wall 27w of each compartment 7a. The two air vents 29 for adsorption tool mounting are formed in two, so that each compartment 7a is lost at the other end side of the rotor for adsorption tool attachment in each passage chamber 7, The cassette adsorption tool 9 is attached to each vent 29 in a state where two cassette adsorption tools 9 are accommodated in each.

The donut plate-shaped common wall member 27 for forming the end wall and the connection portion (one edge portion of the inner cylinder 23) of the inner cylinder 23 are connected to the inner cylinder 23 in the state of being connected to the inner cylinder 23. While mounting the inner cylindrical extension member 30a of the annular shape, the inner circumferential sealing member 33 made of resin which is always slide-contacted to the inner wall 10 by the rotation of the rotor 2 of the inner cylinder extension member 30a is carried out. It is attached to the inner cylinder extension member 30a via the annular support member 30b in the state over the whole circumference, and similarly, the connection part of the donut plate-shaped common wall member 27 for end wall formation, and the outer cylinder 24 is similar. (One edge portion of the outer cylinder 24) attaches the annular outer cylinder extension member 31a over the entire circumference of the outer cylinder 24 in a state continuous to the outer cylinder 24, and at the same time, the rotor 2 The outer peripheral sealing member 34 made of resin which is always in sliding contact with the inner wall 10 in accordance with the rotation of the While you hit the entire circumference of the cylindrical portion extending member (31a) through a support member (31b) of the annular extension it is mounted to the outer cylinder member (31a).

Further, the donut plate-shaped common wall member 27 for forming the end wall and the connecting portion of each partition plate 28 are disposed between the inner cylinder extension member 30a and the outer cylinder extension member 31b in a posture continuous to the partition plate 28. The partition plate sealing member 35 made of resin which is attached to the partition plate extending member 32a which extends, and which slides the windshield wall portions 22a and 22b of the inner wall 10 as the rotor 2 rotates. It is attached to each partition plate extension member 32a via the support member 32b in the state extended to the full length of the extension member 32a, and by the said structure, it is located in the inner wall 10 side rather than the end plate 27w. The inner cylinder extending member 30a and the inner cylinder sealing member support member 30b subsequent thereto (strictly, the tip of the inner cylinder extending member 30a in the supporting member 30b and the inner cylinder sealing member 33). Portion between the substrate) and the outer cylinder extending member 31a and the outer circumferential sealing member subsequent thereto Support member 31b (strictly between the tip of outer cylinder extension member 31a in support member 31b and the base end of outer circumferential sealing member 34) and partition plate extension member 32a and subsequent Enclosure surrounding all directions with the support member 32b for compartment sealing members (strictly the part between the front end of the partition plate extension member 32a in the support member 32b, and the base end of the compartment sealing member 35). The air passage chamber 7 is formed by the enclosing chamber 7b and the partition chamber 7a as the chamber 7b is missing at one end side of the air vent guide rotor in each air passage chamber 7.

That is, in the apparatus of this example, each air passage chamber 7 in the rotor 2 is lost in one end side of the ventilation guide rotor (the enclosure chamber 7b) and the other end side rotor of the rotor for attaching the suction tool (compartment chamber 7a). The end wall 27w which forms the air vent 29 for adsorption tool mounting in the form partitioned by is corresponded to the rotor end side edge (the edge edge of the rotor end side of each partition wall K) of each air passage chamber 7. Position, specifically, the position corresponding to the proximal end of the partition sealing member 35), and the inside of the air passage chamber by a predetermined length d, whereby each air passage chamber in the rotation of the rotor 2 The rotor one end opening of each air passage chamber 7 becomes the outlet side vent of the to-be-processed gas system by the relative movement of the windscreen wall parts 22a and 22b of the inner wall 10 side with respect to the rotor one end opening of (7). 19) or the inlet side vent 21 of the removable gas system, close to the state of being slightly open or fully closed from the state of total closure. Even if a large drift due to narrowing occurs in the gas ventilation between these air vents 19 and 21 and the air passage chambers 7 in the hinged state, the drift is lost in one end loss 7b of the air flow guide rotor. In a state that is effectively alleviated by airflow dispersion and airflow attenuation, the uniform air flow is stably maintained with respect to the mat-type adsorbent layer 8 of the cassette-type adsorption tool 9 mounted on the vent 29 of the end wall 27w. In this way, the gas to be treated A and the gas for detachment G can be vented.

In addition, the partition wall K for partitioning the adjacent air passage chamber 7 is formed to form the ventilation guide rotor one side side lost part 7b. ) And a partition plate extension member 32a for partitioning and forming a partition wall 28 formed by a partition plate 28 for partitioning the partition, and a partition plate extending member 32a for partitioning the rotor end portion 7b (the enclosure chamber) for ventilation guidance. As the divided structure of the extended wall part which consists of a member support member 32b (part between the front-end | tip of the partition plate extension member 32a in the support member 32b, and the base end of the partition sealing member 35), By forming the end wall 27w of each air passage chamber 7 as a donut plate-shaped common wall member 27, the donut plate-shaped common wall member 27 covering the plurality of air passage chambers 7 for maintaining the rotor shape It also functions effectively as a reinforcing member to increase rotor strength The.

In the apparatus of this example, the rotor end side end of the partition wall K is about 30 mm in length (protrusion length from the partition wall K) in the rotor rotation axis center direction of the partition sealing member 35. The distance d between the edge (the position corresponding to the base end of the partition sealing member 35) and the end wall 27w is set to about 50 mm to about 40 mm.

On the other hand, on the other end side of the rotor 2, the inner cylinder 23 and the outer cylinder sealing member 37 made of resin, which are always in sliding contact with the inner wall 11 in accordance with the rotation of the rotor 2, are connected to the inner cylinder 23 and the outside. Rotation of the rotor 2 while being mounted to the end edge portions of the inner cylinder 23 and the outer cylinder 24 via the annular support members 23a and 24a in the state of being spread over the entire circumference of the cylinder 24. The support member in the state which made the resin partition sealing member 38 which made slide contact with the windscreen wall part 18a, 18b of the inner wall 11 the whole length of the rotor plate radial direction of the partition plate 28, It attaches to the edge part of each partition plate 28 through 28a).

Reference numeral 39 is a timing belt wound over the motor drive pulley 41 and the outer cylinder 24 (that is, the outer periphery of the rotor 2) rotated by the motor 40. The timing belt 39 transmits the rotational force of the motor drive pulley 41 to the outer cylinder 24 so that the rotor 2 may be rotated, and the rotor rotation shaft 26 is an idle shaft.

That is, by adopting the rotor drive structure, the torsional moment acting on the rotor rotation shaft 26 is made smaller than the rotation of the rotor 2 by driving the rotor rotation shaft 26 using a gear mechanism or the like. The outer cylinder 24 which is a large-diameter cylindrical body in the state which enables the small diameter of the rotor rotating shaft 26 and used the timing belt 39 wound around the outer cylinder 24 as a reinforcement means with respect to the outer cylinder 24 is carried out. It is also possible to make the plate | board material which forms the outer cylinder 24 thinner by improving the shape retention of ().
