Description

  The present invention relates to a rotor type air treatment device used for air treatment such as air dehumidification and air purification.

  More specifically, an adsorption rotor comprising a breathable adsorbent layer in which a plurality of aggregates are arranged radially in the rotor rotation direction, and a treatment area, a regeneration area, and a purge area are arranged in that order in the rotation area of the adsorption rotor. Arranged in the rotor rotation direction to form compartments, and in parallel with the rotation of the adsorption rotor, the processing area is ventilated in the direction of the rotor rotation axis in a state where the air to be processed passes through the adsorbent layer portion located in the processing area, In the regeneration zone, a high-temperature regeneration gas is passed through the adsorbent layer portion located in the regeneration zone, and is passed in the direction of the rotor rotation axis. In the purge zone, the purge gas is adsorbed in the purge zone. The present invention relates to a rotor type air treatment device that ventilates in the direction of a rotor rotation axis while passing through a layer portion.

  Conventionally, the following apparatus has been proposed as this type of rotor type air treatment apparatus (see Patent Document 1).

  A heat transfer path is individually provided for each of the aggregates (partition walls) arranged radially in the adsorption rotor.

  In this structure, in parallel with the rotation of the adsorption rotor, the heat recovery fluid is passed through the aggregate heat transfer path located in the purge zone after the regeneration zone among the radially arranged aggregates. Of the adsorbent layer, the retained heat of the adsorbent layer portion located in the purge zone (that is, the adsorbent layer portion heated by the high-temperature regeneration air in the previous regeneration zone) is recovered in the heat recovery fluid.

  Following this, the heat recovery fluid after heat recovery is passed along with the rotation of the adsorption rotor and passed through the aggregate heat transfer path located in the preheating area before the regeneration area, thereby using the recovered heat. In the rotor adsorbent layer, the adsorbent layer portion located in the preheating area is preheated prior to heating in the regeneration area.

  In parallel with the rotation of the adsorption rotor, the cooling fluid is passed through the aggregate heat transfer path of the aggregate located in the treatment area among the aggregates in the radial arrangement. As the air to be treated is passed through the adsorbent layer portion positioned, the adsorbent layer portion is cooled by the cooling fluid, and this cooling improves the adsorption performance of the adsorbent layer portion located in the treatment area, Increase processing efficiency for processing air.

  However, this type of rotor-type air treatment apparatus has a problem that the treatment efficiency for the air to be treated fluctuates periodically with the rotation of the adsorption rotor.

  In other words, in the case of air dehumidification processing, when the air to be treated is dehumidified by adsorption of moisture by the adsorbent layer in the treatment area, the humidity of the dehumidified air sent out as treated air from the treatment area varies with the processing efficiency. As a result, there is a problem of periodic rise as shown by graph 1 in FIG.

  In the case of air purification treatment, in the treatment area, the concentration of the pollutant in the purified air sent out from the treatment area as treated air is purified by purifying the air to be treated by adsorption of the contaminants by the adsorbent layer. There has been a problem of periodic increase due to fluctuations in processing efficiency.

  And even if it is a proposal apparatus in above-mentioned patent document 1, although processing efficiency can improve, the above periodic efficiency fluctuations cannot be avoided.

  In view of this situation, the main problem of the present invention is to effectively solve the above problems by rational improvements.

The first characteristic configuration of the rotor type air treatment device according to the present invention is as follows.
An adsorption rotor composed of a breathable adsorbent layer in which a plurality of aggregates are arranged radially in the rotor rotation direction,
A processing area, a regeneration area, and a purge area are arranged in this order in the rotation direction of the rotor in the rotation area of the adsorption rotor,
In parallel with the rotation of the adsorption rotor, the processing area is ventilated in the direction of the rotor rotation axis in a state where the air to be processed is passed through the adsorbent layer portion located in the processing area,
In the regeneration zone, a high-temperature regeneration gas is passed through the adsorbent layer part located in the regeneration zone, and is passed in the rotor rotation axis direction,
The purge area is a rotor-type air treatment device that vents the purge gas in the direction of the rotor rotation axis while allowing the purge gas to pass through the adsorbent layer portion located in the purge area,
Separately from the heating by the heat transfer from the adsorbent layer portion located in the regeneration zone and the heating by the heat transfer from the high temperature regeneration gas passing through the adsorbent layer portion, in parallel with the rotation of the adsorption rotor , setting an auxiliary heating means for heating the aggregate positioned in the regeneration zone selectively,
As this auxiliary heating means, a heat transfer path for heat transfer of the aggregate is individually equipped for each of the aggregates arranged in the rotor rotation direction,
Along with the rotation of the adsorption rotor, a part of the high-temperature regeneration gas heated by the regeneration heating means is selectively applied to the aggregate heat transfer path located in the regeneration zone of the heat transfer path. Pass through
The other part of the high temperature regeneration gas heated by the regeneration heating means is passed through the adsorbent layer portion located in the regeneration zone,
The inlet of the heat transfer path is formed at the end surface portion on the regeneration gas inlet side of the adsorption rotor in the vicinity of the corresponding aggregate in the rotor rotation direction .

  It has been found that the periodic fluctuations in the processing efficiency described above are caused by a plurality of aggregates arranged radially in the adsorption rotor.

  That is, (see FIG. 1), the portion where the aggregate 25 is disposed in the adsorption rotor 1 is less likely to be heated in the regeneration zone 4 than the aggregate-free portion where the high-temperature regeneration gas HA is allowed to pass. In the direction, the adsorbent layer portion of the aggregate absent portion located in the vicinity of the aggregate placement portion also transfers heat to the aggregate placement portion which is the low temperature portion despite the passage of the high-temperature regeneration air HA ( In particular, due to heat transfer to the aggregate 25, there is a tendency for the regeneration zone 4 to become underheated and to become insufficiently regenerated due to insufficient regeneration during the process of passing through the regeneration zone.

  Then, the periodic fluctuation of the processing efficiency as described above is caused by the fact that the adsorbent layer portion in the vicinity of the aggregate placement portion that has become insufficiently regenerated passes through the treatment zone 3 together with the aggregate placement portion. Occurs.

  Further, in the proposed device described in Patent Document 1 described above, the equipment heat transfer path f of the aggregate 25 (partition wall) located in the regeneration zone HA is in a fluid passage stop state and regenerated due to the staying fluid in the heat transfer path f. The holding capacity of the aggregate arrangement part located in the zone 4 is increased, and this causes the heat transfer to the aggregate arrangement part to cause the adsorbent layer portion near the aggregate arrangement part to be in an insufficiently regenerated state due to insufficient heating. Therefore, periodic fluctuations in processing efficiency tend to be further promoted.

  On the other hand, according to the first characteristic configuration (see FIG. 1), heating by heat transfer from the adsorbent layer portion located in the regeneration zone 4 and high-temperature regeneration gas passing through the adsorbent layer portion. Apart from the heating by heat transfer from the HA, the aggregate 25 located in the regeneration zone 4 is selectively heated by the auxiliary heating means in parallel with the rotation of the adsorption rotor 1, so that the aggregate placement part is placed in the regeneration zone 4. The heat transfer from the adsorbent layer portion in the aggregate-free portion to the aggregate placement portion, and the high-temperature regeneration gas HA that passes through the adsorbent layer portion Heat transfer from the steel to the aggregate placement part can be effectively suppressed.

  In other words, this effectively avoids that the adsorbent layer portion of the aggregate-free portion located in the vicinity of the aggregate placement portion becomes insufficiently heated due to insufficient heating in the regeneration zone 4. Thus, the periodic fluctuation of the processing efficiency as described above can be effectively suppressed.

  In addition, by raising the temperature of the aggregate arrangement portion in the regeneration zone 4 as described above, the high temperature regeneration gas HA that passes through the adsorbent layer portion located in the regeneration zone 4 is increased in the adsorbent layer portion located in the regeneration zone 4. It is possible to efficiently contribute to heating without waste, and to that extent, the processing efficiency can be increased to the air to be treated A, and the air flow rate of the high temperature regeneration gas HA to the regeneration zone 4 can be effectively reduced, Thereby, even if the energy required for the operation of the auxiliary heating means is included, the energy consumption of the entire apparatus can be effectively reduced, which can be further advantageous in terms of energy saving and operation cost.

  Therefore, in the case of air dehumidification treatment, the humidity of the dehumidification air sent out from the treatment area 3 as the treated air A ′ can be stably maintained at a required low value with high accuracy, and energy consumption is also effectively reduced. The device can be made.

  Similarly, in the case of air purification treatment, the concentration of contaminants in the purified air sent from the treatment area 3 as treated air A ′ can be stably maintained at a required low value with high accuracy and energy consumption is also effective. Can be reduced.

Further, in the first characteristic configuration, as the auxiliary heating means, a heat transfer path for heat transfer of the aggregate is individually provided for each of the aggregates arranged in the rotor rotation direction,
In parallel with the rotation of the adsorption rotor, a part of the high-temperature regeneration gas heated by the regeneration heating means is selectively passed through the aggregate heat-transfer path located in the regeneration zone of the heat-transfer path,
Since the other part of the high-temperature regeneration gas heated by the regeneration heating means is passed through the adsorbent layer portion located in the regeneration zone, the following effects are also achieved.

That is, in this configuration (see FIG. 1), the regeneration heating means 16 heats and generates the high-temperature regeneration gas HA that passes through the adsorbent layer portion located in the regeneration zone 4, and is heated by the regeneration heating means 16. The aggregate 25 located in the regeneration zone 4 is selectively heated using a part of the high temperature regeneration gas HA.

Therefore, compared to the case where an apparatus configuration for heating the aggregate 25 located in the regeneration zone 4 using a heating source different from the high-temperature regeneration air HA is adopted, an apparatus configuration in which a dedicated heat source apparatus for heating the aggregate is unnecessary. As a result, the apparatus cost can be reduced and the apparatus can be miniaturized.

Furthermore, in the first characteristic configuration, since the inlet of the heat transfer path is formed on the end surface portion on the regeneration gas inlet side of the adsorption rotor in the vicinity of each of the corresponding aggregates in the rotor rotation direction, the following effects are also obtained. Play.

That is, according to this configuration (see FIG. 1), the high-temperature regeneration gas HA is regenerated from the end surface portion on the regeneration gas inlet side of the adsorption rotor 1 (the end surface portion on one side in the rotor rotation axis direction) in the regeneration zone 4. Along with passing through the adsorbent layer portion located in the zone 4, a part of the high temperature regeneration gas HA of the plurality of heat transfer path inlets fi formed on the end surface portion of the adsorption rotor 1 on the regeneration gas inlet side is provided. Of these, the heat transfer path inlet fi located in the regeneration zone 4 can be passed through the equipment heat transfer path f of the aggregate 25 located in the regeneration zone 4.

That is, according to this configuration, a dedicated flow path switching means for selectively passing a part of the high temperature regeneration gas HA through the equipment heat transfer path f of the aggregate 25 located in the regeneration zone 4 is not necessary. Therefore, the device configuration can be further simplified.

The second characteristic configuration of the rotor type air treatment device according to the present invention is as follows.
Separately from the cooling by the heat radiation to the adsorbent layer portion located in the purge zone and the cooling by the heat radiation to the purge gas passing through the adsorbent layer portion, the purge is performed in parallel with the rotation of the adsorption rotor. Providing auxiliary cooling means for selectively cooling the aggregate located in the zone,
A configuration in which the cooling fluid is passed through the aggregated heat transfer path located in the purge area, with the aggregated heat transfer path located in the purge area as the auxiliary cooling means in the heat transfer path. It is in a certain point.

According to this configuration (see FIG. 1), while the aggregate 25 located in the regeneration zone 4 is heated by the auxiliary heating means as described above, in the purge zone 5 following the regeneration zone 4, the purge zone 5 is changed as described above. Separately from the cooling by the heat radiation to the adsorbent layer portion positioned and the cooling by the heat radiation to the purge gas PA passing through the adsorbent layer portion, the aggregate 25 located in the purge area 5 is used as an auxiliary cooling means. By selectively cooling by the passage of the cooling fluid to the equipment heat transfer path f, the aggregate placement portion can be efficiently cooled in the purge zone 5 prior to the processing zone 3, and the purge zone accordingly. Thus, the purge gas PA that is ventilated to the gas can be efficiently contributed to cooling the adsorbent layer portion located in the purge zone 5 without waste.

That is, this makes it possible to effectively avoid a reduction in processing efficiency due to a high temperature in the processing area 3, and prevent the insufficient heating in the regeneration area 4 as described above and sufficiently regenerate the adsorbent layer portion. Can be effectively treated with respect to the air to be treated A in the treatment area 3.

Further, since the purge gas PA can efficiently contribute to the cooling of the adsorbent layer portion located in the purge zone 5, the ventilation amount of the purge gas PA to the purge zone 5 can be effectively reduced. As a result, the energy consumption of the entire apparatus can be further effectively reduced.

The third characteristic configuration of the rotor type air treatment device according to the present invention is as follows.
The direction of ventilation of the high temperature regeneration gas with respect to the regeneration area and the direction of ventilation of the purge gas with respect to the purge area are the same in the rotor rotation axis direction,
A part of the high temperature regeneration gas supplied from the regeneration heating means to the regeneration region flows into the inlet of the heat transfer path located in the regeneration region,
A part of the purge gas supplied to the purge zone flows into the inlet of the heat transfer path located in the purge zone.

  According to this configuration (see FIG. 1), a part of the high temperature regeneration gas HA is caused to flow from the heat transfer path inlet fi located in the regeneration zone 4 into the equipment heat transfer path f of the aggregate 25 located in the regeneration zone 4. As the aggregate 25 located in the regeneration zone 4 is heated, the equipment heat transfer path f of the aggregate 25 located in the purge zone 5 is used as the auxiliary cooling means from the heat transfer path inlet fi located in the purge zone 5. A part of the purge gas PA is caused to flow into the equipment heat transfer path f of the aggregate 25 located in the purge zone 5, and the aggregate 25 located in the purge zone 5 is selectively cooled by the inflow purge gas PA. Can do.

  That is, according to this configuration, a part of the high-temperature regeneration gas HA is selectively passed through the equipment heat transfer path f of the aggregate 25 located in the regeneration zone 4 and the aggregate located in the purge zone 5 The aggregate 25 located in the purge zone 5 is moved to the purge zone 5 while eliminating the need for a dedicated channel switching means for selectively passing a part of the purge gas PA through the equipment heat transfer path f. Separately from cooling by heat radiation to the adsorbent layer portion positioned and cooling by heat radiation to the purge gas PA passing through the adsorbent layer portion, cooling is effectively performed using a part of the purge gas PA. can do.

The fourth characteristic configuration of the rotor type air treatment device according to the present invention is as follows.
Forming an outlet of the heat transfer path on an outer peripheral surface portion of the adsorption rotor in the vicinity of each of the corresponding aggregates in the rotor rotation direction;
Of the outer peripheral portion in the rotation region of the adsorption rotor, an exhaust chamber for receiving the gas discharged from the outlet of the heat transfer path is formed in a portion corresponding to the regeneration region and a portion corresponding to the purge region,
A recovery exhaust path is provided for guiding the exhaust gas received in the exhaust chamber to the regeneration heating means.

  In this configuration (see FIG. 1), the gas HA ″ discharged from the heat transfer path outlet fo located in the regeneration zone 4 (that is, in the regeneration zone 4 as it flows from the heat transfer path inlet fi located in the regeneration zone 4). The high-temperature regeneration gas HA ″) used for heating the aggregate 25 located in the position is discharged from the heat transfer path outlet fo located in the purge area 5 along with the inflow from the heat transfer path inlet fi located in the purge area 5. Gas PA ″ (that is, the purge gas PA ″ used for cooling the aggregate 25 located in the purge zone 5) is received in the exhaust chamber 31.

  The exhaust gases HA ″ and PA ″ received in the exhaust chamber 31 are guided to the regeneration heating means 16 through the recovery exhaust passage 33, so that the retained heat of the exhaust gases HA ″ and PA ″ (that is, the regeneration zone 4). In the state where the residual heat of the high temperature regeneration gas HA ″ used for heating the aggregate 25 and the heat recovered in the purge gas PA ″ in the cooling of the aggregate 25 in the purge zone 5 is effectively used, The regeneration heating means 16 heats and generates the high temperature regeneration gas HA that supplies the exhaust gases HA ″ and PA ″ as raw material gases to the regeneration zone 4.

  Therefore, according to this configuration, the energy consumption of the regeneration heating means 16 that generates the high temperature regeneration gas HA can be effectively reduced, which can be further advantageous in terms of energy saving and operation cost.

The fifth characteristic configuration of the rotor type air treatment device according to the present invention is:
A recovery fan that supplies the gas discharged from the outlet of the heat transfer path located in the regeneration zone and the gas discharged from the outlet of the heat transfer path located in the purge zone to the heating means for regeneration. It is in the point which is provided.

  According to this configuration (see FIG. 8), the gas HA ″ and PA ″ discharged from each heat transfer path outlet fo can be reliably sent to the regeneration heating means 16 by the blowing function of the recovery fan 35. Thus, the apparatus can be reliably and stably operated in an intended operation state.

  Further, it is possible to promote gas passage in each heat transfer path f by the suction action of the recovery fan 35, and as a result, aggregate by passing a part of the high temperature regeneration gas HA through the heat transfer path f. Thus, the cooling of the aggregate 25 by passing a part of the purge gas PA through the heat transfer path f can be made more effective.

The sixth characteristic configuration of the rotor type air treatment device according to the present invention is as follows.
The ventilation direction of the air to be treated with respect to the treatment area and the ventilation direction of the high temperature regeneration gas with respect to the regeneration area are opposite to each other in the rotor rotation axis direction.

  In other words (see FIG. 1), if the outlet fo of the heat transfer path f is provided on the outer peripheral surface of the adsorption rotor 1 as described above, the direction of ventilation of the air to be treated A with respect to the treatment area 3 and the high temperature regeneration with respect to the regeneration area 4 Even if the ventilation direction of the gas HA is opposite to each other as described above, a part of the air to be treated A that is ventilated in the processing zone 3 is located in the processing zone 3 from the heat transfer path outlet fo located in the processing zone 3. By entering the heat transfer path f of the aggregate 25 and passing through the adsorbent layer located in the processing area 3 and not being processed, it is possible to prevent the through leakage sent from the processing area 3.

  And according to the said structure, the ventilation direction of the to-be-processed air A with respect to the process area 3 and the ventilation direction of the high temperature reproduction | regeneration gas HA with respect to the reproduction | regeneration area 4 are prevented, preventing such a through leakage of the to-be-processed air A. Are made to be opposite to each other in the rotor rotation axis direction, so that the air to be treated advances in the adsorbent layer portion located in the processing area 3 and the processing proceeds, so that the adsorbent layer has a higher degree of regeneration in the regeneration area 4. The entire amount of air to be treated A can be passed through the adsorbent layer portion located in the processing zone 3 in a passing configuration in which the air is positioned, thereby further effectively increasing the processing efficiency for the air to be processed A. be able to.

In the implementation of any one of the first to sixth characteristic configurations of the rotor type air treatment device according to the present invention, a short-circuit air flow from the heat transfer path inlet fi to the heat transfer path outlet fo is generated inside the heat transfer path f. On the inner wall surface of the heat transfer path f, there is provided a passing air flow guide means for preventing the heat transfer from being formed or a heat transfer projection for promoting heat transfer between the passing gas and the aggregate 25 in the heat transfer path f. It may be provided.

  FIG. 1 shows a rotor-type air dehumidifier, and 1 is an adsorption rotor composed of a breathable adsorbent layer X such as a honeycomb structure, and this adsorbent layer X holds an adsorbent such as zeolite or activated carbon. .

  In the rotation area 2 of the adsorption rotor 1, a processing area 3, a regeneration area 4, and a purge area 5 are arranged in the rotor rotation direction R in that order, and are partitioned and formed as the adsorption rotor 1 rotates. The adsorbent layer X is repeatedly positioned in the processing zone 3, the regeneration zone 4, and the purge zone 5 in that order.

  In FIG. 1, the suction rotor 1 and its rotation region 2 are developed in the rotor rotation direction R for easy understanding.

  Through the air to be treated 3, the air to be treated A to be dehumidified supplied by the air supply fan 7 is passed through the air to be treated 6, and the air to be treated A is removed from the rotor adsorbent layer X by the ventilation. By passing it through the adsorbent layer portion located at the position, the air to be treated A is dehumidified by moisture adsorption by the adsorbent layer X during the passage process.

  The processed air A ′ dehumidified in the processing area 3 is supplied to the adjustment target chamber 9 through the processed air passage 8 as the adjustment air SA, thereby adjusting the interior of the adjustment target chamber 9 to a predetermined low humidity state.

  The air A to be treated is a mixed air of the outside air OA and the return air RA returning from the adjustment target chamber 9, introduces the outside air OA through the outside air introduction path 10, and uses the room air in the adjustment target chamber 9 as the return air RA. The air led out to the return air passage 11 and combined with the introduced outside air OA and the return air RA is supplied to the treatment area 3 through the treatment air passage 6 as the treatment air A.

  Further, along with the supply of the adjustment air SA to the adjustment target chamber 9, the indoor air having an air volume corresponding to the introduction air amount of the outside air OA through the external air introduction path 10 is discharged from the adjustment target chamber 9 through the exhaust path 12 as the exhaust air EA. .

  Reference numeral 13 denotes an outside air processing cooler that cools the outside air OA introduced through the outside air introduction path 10, and reference numeral 14 denotes a return air processing cooler that cools the return air RA guided through the return air path 11, and the outside air OA and return by these coolers 13 and 14. By reducing the temperature of the air to be treated A by cooling the air air RA, the dehumidifying efficiency of the air to be treated A in the treatment area 3 (in other words, the moisture adsorption efficiency of the adsorbent layer X) is increased.

  Reference numeral 15 denotes an after-heating for heating the adjustment air SA supplied to the adjustment target chamber 9 through the processed air passage 8 to a required temperature corresponding to the use of the adjustment target chamber 9 for cooling by the outside air processing cooler 13 and the return air processing cooler 14. It is a heater.

  A high temperature regeneration air HA supplied by a regeneration fan 18 is passed through a regeneration heater 16 (an example of a regeneration heating means) from a regeneration heater 16 through a regeneration air supply path 17, and this ventilation allows high temperature regeneration. By passing the air HA through the adsorbent layer portion located in the regeneration zone 4 of the rotor adsorbent layer X, the adsorbent layer portion located in the regeneration zone 4 is heated, and the adsorbent layer portion is processed in the previous process. The moisture adsorbed from the air to be treated A in the zone 3 is desorbed, and thereby the adsorbent layer portion located in the regeneration zone 4 is regenerated.

  The direction of ventilation of the high-temperature regeneration air HA with respect to the regeneration zone 4 and the direction of ventilation of the air to be treated A with respect to the treatment zone 3 are opposite to each other in the rotor rotation axis direction. Is passed through the adsorbent layer portion in the regeneration zone from one end surface portion (end surface portion on the regeneration air inlet side) in the rotational axis direction of the adsorption rotor 1, whereas in the treatment zone 3, the air to be treated A The adsorption rotor 1 is passed through the adsorbent layer portion in the treatment area from the other end surface portion (end surface portion on the treated air inlet side) in the rotation axis direction.

  Thus, the adsorbent layer portion located in the processing area 3 is made by reversing the airflow direction of the high temperature regeneration air HA with respect to the regeneration area 4 and the airflow direction of the air to be processed A with respect to the processing area 3. As the air to be treated A advances and the dehumidification progresses, an adsorbent layer having a higher degree of regeneration in the regeneration zone 4 is positioned, thereby ensuring high dehumidification efficiency for the air to be treated A.

  Part of the processed air A ′ dehumidified in the processing area 3 and sent to the processed air path 8 is diverted to the purge air supply path 19 on the upstream side of the after heater 15. The treated air A ′ divided into the purge air supply passage 19 is vented in the same direction as the ventilation direction of the high-temperature regeneration air HA to the regeneration zone 4 as purge air PA.

  By this ventilation, the purge air PA is passed through the adsorbent layer portion located in the purge region 5 of the rotor adsorbent layer X, so that the adsorbent layer portion heated in the previous regeneration region 4 is purged. By this cooling, the adsorbent layer portion regenerated in the regeneration zone 4 is efficiently dehumidified (moisture adsorption function) for the air to be treated A in the next treatment zone 3.

  Part of the used high-temperature regeneration air HA ′ sent from the regeneration zone 4 to the regeneration exhaust passage 20 passes through the regeneration circulation passage 21 by the blowing action of the regeneration fan 18 interposed in the regeneration exhaust passage 20. A purge exhaust path 22 is connected to the regeneration circulation path 21 and leads the used purge air PA ′ sent from the purge zone 5 to the regeneration circulation path 21.

  That is, a part of the used high-temperature regeneration air HA ′ sent from the regeneration zone 4 and the used purge air PA ′ sent from the purge zone 5 are passed through the regeneration circuit 21 to the regeneration heater 16. The spent air HA ′, PA ′ is heated by the regeneration heater 16 to generate the high temperature regeneration air HA to be supplied to the regeneration zone 4.

  In this way, by using a part of the used high temperature regeneration air HA ′ and the used purge air PA ′ as raw material air, the high temperature regeneration air HA is heated and generated, so that the used high temperature regeneration air HA ′ is used. The high-temperature regeneration air HA is heated and generated using the residual heat held by the gas and the recovered heat held by the used purge air PA ′ (that is, the recovered heat from the adsorbent layer portion located in the purge zone 5). This reduces the energy required to generate the high temperature regeneration air HA.

  The remaining portion of the used high-temperature regeneration air HA ′ delivered from the regeneration zone 4 is discharged out of the apparatus through the regeneration exhaust passage 20.

  As shown in FIG. 2, the adsorption rotor 1 includes, as a structural material, a rotor rotating shaft 23 located at the center of the rotor, a rotor outer peripheral rim 24 that forms a rotor outer peripheral surface, and the rotor rotating shaft 23 and the rotor outer peripheral rim 24. The spoke-like aggregate 25 is arranged in four radial positions, arranged at equal intervals in the rotor rotation direction.

  The adsorbent layer X having a honeycomb structure is divided into a plurality of adsorbent layer blocks xb in the rotor rotation direction, and each of the adsorbent layer blocks xb is spoke-shaped between the rotor rotation shaft 23 and the rotor outer peripheral rim 24. The adsorption rotor 1 is configured by being housed and arranged between the aggregates 25.

  25 a is a seal member that seals between the adsorbent layer block xb and the aggregate 25, and P is the rotor rotation axis and the center axis of the rotor rotation axis 23.

  As shown in FIG. 3, at one end portion of the rotation region 2 of the adsorption rotor 1 in the rotor rotation axis direction, an opening is formed with respect to one end surface portion (end surface portion on the regeneration air inlet side) of the adsorption rotor 1. Are arranged in close proximity to each other, and similarly, at the other end of the rotation region 2 of the suction rotor 1 in the direction of the rotor rotational axis, the other end surface portion (covered) of the suction rotor 1 is disposed. The supply / discharge chamber 27 on the other side is arranged with the opening facing the process air inlet side end face).

  The supply / discharge chamber 26 on one side corresponds to a processing area outlet chamber 3o positioned corresponding to the processing area 3, a regeneration area inlet chamber 4i corresponding to the regeneration area 4, and a purge area 5 by a partition wall 26a. The supply / exhaust chamber 27 on the other side is partitioned by a partition wall 27a and a regeneration region inlet chamber 3i positioned corresponding to the treatment region 3 and a regeneration region 4 Is divided into a regeneration zone outlet chamber 4o positioned corresponding to the purge zone 5 and a purge zone outlet chamber 5o positioned corresponding to the purge zone 5.

  That is, by connecting the processing air passage 6 to the processing region inlet chamber 3i in the other supply / discharge chamber 27 and connecting the processed air passage 8 to the processing region outlet chamber 3o in the one supply / discharge chamber 26. The structure is such that the air to be treated A is passed through the treatment area 3 and passed through the adsorbent layer portion located in the treatment area 3.

  Further, the regeneration air supply path 17 is connected to the regeneration area inlet chamber 4 i in the one supply / discharge chamber 26, and the regeneration exhaust path 20 is connected to the regeneration area outlet chamber 4 o in the other supply / discharge chamber 27. Thus, the high-temperature regeneration air HA is passed through the regeneration zone 4 and passed through the adsorbent layer portion located in the regeneration zone 4.

  Further, the purge air supply path 19 is connected to the purge area inlet chamber 5i in the one supply / discharge chamber 26, and the purge exhaust path 22 is connected to the purge area outlet chamber 5o in the other supply / discharge chamber 27. Thus, the purge air PA is ventilated through the purge zone 5 and passed through the adsorbent layer portion located in the purge zone 5.

  As shown in FIGS. 2 to 5, the spoke-like aggregate 25 positioned between the adsorbent layer blocks xb adjacent to each other in the adsorption rotor 1 extends over the entire length of the adsorption rotor 1 in the rotor rotation axis direction, and A flat box structure extending from the rotor rotary shaft 23 to the rotor outer peripheral rim 24 in the rotor rotational radius direction, and a side surface portion on one side in the rotor rotational axis direction in the flat box structure serves as a heat transfer path inlet fi. 1 is opened at one end face (end face on the regeneration air inlet side).

  Of the side surface portion of the rotor 25 in the flat box structure of the aggregate 25, the portion near the other end surface portion (end surface portion of the air inlet to be treated) of the adsorption rotor 1 serves as the heat transfer path outlet fo. Accordingly, the inside of the box in the flat box structure of each aggregate 25 is a heat transfer path f provided for each aggregate 25.

  On the inner wall surface of the heat transfer path f, a plurality of heat transfer ribs 28 (an example of heat transfer protrusions) that promote heat transfer between the air passing through the heat transfer path f and the aggregate 25 are formed. In addition, in the inside of the flat box structure of the aggregate 25, a short-circuited linear air flow from the heat transfer path inlet fi to the heat transfer path outlet fo is prevented from being formed inside the heat transfer path f. Thus, an airflow guide plate 29 (an example of a passing airflow guide means) that makes the heat transfer path f a substantially bent flow path is provided.

  While the outlet fo of each heat transfer path f is formed in the rotor outer rim 24, the outer peripheral portion in the rotation region 2 of the adsorption rotor 1 has an opening adjacent to the entire outer periphery of the rotor outer rim 24. An annular chamber 30 is disposed inside the annular chamber 30 by a partition wall 30a. The exhaust chamber 31 is positioned corresponding to the regeneration region 4 and the purge region 5 in the rotor rotational direction, and the processing region 3 in the rotor rotational direction. And a closed chamber 32 corresponding to each other.

  That is, in the regeneration zone 4, the high temperature regeneration air HA supplied to the regeneration zone inlet chamber 4 i in the supply / discharge chamber 26 on one side through the regeneration air supply path 17 is located in the regeneration zone 4 of the rotor adsorbent layer X. Along with passing through the adsorbent layer portion, a part of the high-temperature regeneration air HA supplied to the regeneration zone inlet chamber 4i is aligned in the rotor rotation direction at one end face of the adsorption rotor 1 in the rotor rotation direction. Of the fi, the heat transfer path inlet fi located in the regeneration zone 4 (that is, the heat transfer path inlet fi facing the regeneration zone inlet chamber 4i) flows into the heat transfer path f of the aggregate 25 located in the regeneration zone 4 To pass through.

  As a result, heating by heat transfer from the adsorbent layer portion located in the regeneration zone 4 and passing through the adsorbent layer portion using the equipment heat transfer path f of the aggregate 25 located in the regeneration zone 4 as auxiliary heating means. In addition to heating by heat transfer from the high temperature regeneration air HA, the aggregate 25 located in the regeneration zone 4 is selectively and directly heated by the high temperature regeneration air HA that passes through the equipment heat transfer path f. Thereby, the aggregate arrangement part located in the reproduction | regeneration area 4 among the aggregate arrangement parts (namely, boundary part between adsorption agent layer blocks xb) of the several places in the adsorption | suction rotor 1 is heated efficiently.

  That is, the arrangement portion of the aggregate 25 in the adsorption rotor 1 is less likely to be heated in the regeneration region 4 than the aggregate-free portion where the high temperature regeneration gas HA can pass, and therefore the aggregate arrangement in the rotor rotation direction. The adsorbent layer part of the aggregate-free part located in the vicinity of the part also has a regeneration zone 4 for heat transfer to the aggregate placement part which is the low temperature part, despite the passage of the high temperature regeneration air HA. In this case, there is a tendency to be in a state of insufficient regeneration that is not sufficiently regenerated in the process of passing through the regeneration zone.

  And the dehumidification efficiency with respect to the to-be-processed air A is periodic because the adsorbent layer part in the vicinity of the aggregate placement part that has become insufficiently regenerated passes through the treatment zone 3 together with the aggregate placement part. The humidity of the processed air A ′ sent out from the processing area 3 (ie, the humidity of the adjustment air SA supplied to the adjustment target chamber 9) periodically rises as shown in the graph 1 in FIG. Problem arises.

  On the other hand, as described above, apart from heating by heat transfer from the adsorbent layer portion located in the regeneration zone 4 and heating by heat transfer from the high-temperature regeneration air HA passing through the adsorbent layer portion, Along with the rotation of the adsorption rotor 1, the aggregate 25 located in the regeneration zone 4 is selectively and directly heated by the high-temperature regeneration air HA passing through the equipment heat transfer path f to be located in the regeneration zone 4. By efficiently raising the temperature of the aggregate placement section, the periodic dehumidification efficiency as described above can be prevented and the average dehumidification efficiency can be improved. As a result, as shown in the graph 2 of FIG. The humidity of the processed air A ′ sent out from No. 3 can be further reduced and maintained stably with high accuracy.

  As part of the high-temperature regeneration air HA supplied to the regeneration zone inlet chamber 4i passes through the equipment heat transfer path f of the aggregate 25 located in the regeneration area 4, the outlet heat fo of the equipment heat transfer path f The exhausted high-temperature regeneration air HA ″ that is discharged is received by the exhaust chamber 31 in the annular chamber 30.

Similarly, in the purge zone 5, the purge air PA supplied to the purge zone inlet chamber 5 i in the supply / discharge chamber 26 on one side through the purge air passage 19 is positioned in the purge zone 5 of the rotor adsorbent layer X. A part of the purge air PA supplied to the purge zone inlet chamber 5i is lined up in the rotor rotation direction at one end surface of the adsorption rotor 1 in parallel with passing through the adsorbent layer portion. The heat transfer path f of the aggregate 25 located in the purge zone 5 is caused to flow into the heat transfer path inlet fi located in the purge zone 5 (ie, the heat transfer passage inlet fi facing the purge zone inlet chamber 5i). To pass through.

  That is, by passing the purge air PA through the equipment heat transfer path f of the aggregate 25 located in the purge zone 5 in this way, the equipment heat transfer path f of the aggregate 25 located in the purge zone 5 is passed through the auxiliary cooling means. In addition to the cooling by the heat radiation to the adsorbent layer portion located in the purge area 5 and the cooling by the heat radiation to the purge air PA passing through the adsorbent layer portion, the aggregate 25 located in the purge area 5 Is selectively and directly cooled by the purge air PA passing through the heat transfer path f.

  Thus, the aggregate placement portion (that is, the aggregate placement portion heated in the previous regeneration zone 4) is efficiently cooled in the purge zone 5 prior to the processing zone 3, and the adsorption located in the purge zone 5 correspondingly. The purge air PA vented to the agent layer portion is allowed to efficiently contribute to the cooling of the adsorbent layer portion located in the purge zone 5 without waste, thereby preventing insufficient heating in the regeneration zone 4 as described above. The sufficiently regenerated adsorbent layer portion is effectively dehumidified with respect to the air to be treated A in the treatment zone 3.

  As part of the purge air PA supplied to the purge zone inlet chamber 5i passes through the equipment heat transfer path f of the aggregate 25 located in the purge area 5, it is discharged from the outlet fo of the equipment heat transfer path f. The used purge air PA ″ is used in the exhaust chamber 31 of the annular chamber 30 together with the used high-temperature regeneration air HA ″ discharged from the equipment heat transfer path f of the aggregate 25 located in the regeneration zone 4. Accepted.

  FIG. 7 is a comparison table between the rotor-type air dehumidifying apparatus not provided with the heat transfer path f as described above and the rotor-type air dehumidifying apparatus provided with the heat transfer path f. In the rotor type air dehumidifier provided with f, the adsorbent layer portion located in the regeneration zone 4 while effectively preventing periodic humidity fluctuations of the treated air A ′ delivered from the treatment zone 3 as described above. The amount of air required for the high-temperature regeneration air HA can be reduced by the amount that can efficiently contribute to the heating of the adsorbent layer portion located in the regeneration zone 4, and the purge zone. The amount of air required for the purge air PA can be reduced by the amount that the purge air PA passing through the adsorbent layer portion located at 5 can efficiently contribute to cooling the adsorbent layer portion located in the purge zone 5. This also makes the energy consumption of the device effective. It can be reduced.

  Since the outlet fo of each heat transfer path f is formed in the rotor outer peripheral rim 24, the air to be processed A supplied to the processing area inlet chamber 3i in the supply / discharge chamber 27 on the other side through the air flow path 6 to be processed is treated. It is prevented from flowing into the equipment heat transfer path f of the aggregate 25 located in the zone 3, whereby the air to be treated A is not subjected to the dehumidification treatment by the adsorbent layer X through the equipment heat transfer path f of the aggregate 25. It is prevented from being sent outside.

  That is, the entire amount of the air to be processed A supplied to the processing area inlet chamber 3i in the other supply / exhaust chamber 27 passes through the adsorbent layer portion located in the processing area 3 of the rotor adsorbent layer X and dehumidifies. After being processed, it is guided to the processing area outlet chamber 3o in the supply / discharge chamber 26 on one side.

  The exhaust chamber 31 in the annular chamber 30 is connected to the suction side portion of the regeneration fan 18 in the regeneration exhaust passage 20 through the recovery exhaust passage 33, and thus the used high temperature regeneration received in the exhaust chamber 31. The air HA ″ and the used purge air PA ″ (that is, the air that has passed through the heat transfer path f of the aggregate 25) are recovered through the recovery exhaust path 33 by the suction action of the regeneration fan 18, and the regeneration exhaust path 20. Led to.

  That is, with this structure, the regeneration fan 18 is used as a recovery fan. By the suction action of the regeneration fan 18, the high-temperature regeneration air HA with respect to the equipment heat transfer path f of the aggregate 25 located in the regeneration zone 4 is obtained. And the passage of the purge air PA to the heat transfer path f of the aggregate 25 located in the purge zone 5 and the heating of the aggregate 25 located in the regeneration zone 4 and the bone located in the purge 5 The cooling of the material 25 is further promoted.

  Further, a part of the used high-temperature regeneration air HA ″ received in the exhaust chamber 31 and a part of the used purge air PA ″ are exhausted from the regeneration zone 4 by the blowing function of the regeneration fan 18. A part of the used high-temperature regeneration air HA ′ sent to the passage 20 and the used purge air PA ′ sent from the purge zone 5 to the purge exhaust passage 22 together with the regeneration circulation passage 21 for high-temperature regeneration. As a raw material air for the production air HA, it is sent to the regeneration heater 16 so that the retained heat of the used high temperature regeneration air HA ″ and the used purge air PA ″ received in the exhaust chamber 31 (that is, the regeneration region). The residual heat of the high temperature regeneration gas HA ″ used for heating the aggregate in 4 and the heat recovered in the purge air PA ″ in the cooling of the aggregate in the purge zone 5) are also used to generate the high temperature regeneration air HA. To use A.

  In this structure, in addition to the regeneration fan 18, a recovery fan is additionally provided in the recovery exhaust passage 33, whereby the high-temperature regeneration air HA for the equipment heat transfer path f of the aggregate 25 located in the regeneration zone 4. And the passage of the purge air PA to the equipment heat transfer path f of the aggregate 25 located in the purge zone 5 may be further promoted.

  In the annular chamber 30, a seal member 34 that seals a gap between the partition wall 30 a and the rotor outer rim 24 while allowing the suction rotor 1 to rotate is provided at the tip of the partition wall 30 a that partitions the exhaust chamber 31 and the closed chamber 32. As a result, the processed air A ′ received in the processing area outlet chamber 3 o in the supply / exhaust chamber 26 on one side passes through the equipment heat transfer path f of the aggregate 25 located in the processing area 3 and the closing chamber 32. Intrusion into the exhaust chamber 31 is prevented.

The raw material air of HA may be sent to the regeneration heater 16.

  Further, in this case, the recovery fan 35 is interposed in the recovery exhaust passage 33, the passage of the high-temperature regeneration air HA to the equipment heat transfer path f of the aggregate 25 located in the regeneration zone 4, and the purge 5 It is desirable to facilitate the passage of the purge air PA to the equipment heat transfer path f of the aggregate 25 located.

The used purge air PA ″ is received in the common exhaust chamber 31. Instead of this, the used high temperature regeneration that has passed through the heat transfer path f of the aggregate 25 located in the regeneration zone 4 is used. An exhaust chamber that receives the air HA ″ and an exhaust chamber that receives the used purge air PA ″ that has passed through the heat transfer path f of the aggregate 25 located in the purge zone 5 may be provided separately.

  In that case, the used high-temperature regeneration air HA ″ that has passed through the equipment heat transfer path f of the aggregate 25 located in the regeneration zone 4 and the equipment heat transfer path f of the aggregate 25 located in the purge zone 5 have passed. Only one of the used purge air PA ″ is sent to the regeneration heater 16 so that the destinations of the used high temperature regeneration air HA ″ and the used purge air PA ″ are made different.
