Abstract

PROBLEM TO BE SOLVED: To increase the adsorbing and desorbing capacities of an adsorbing and desorbing device while suppressing the increase of power consumption as much as possible. SOLUTION: An adsorption part 11 is installed in the prescribed area of an adsorbing and desorbing rotor 1. A heat storage part 12, a desorption part 13, and a heat recovery part 14 are installed sequentially on the forward side in the rotation direction of the adsorption part 11 so as to face forward in the rotation direction. Air to be treated A1 is made to flow through a part corresponding to the adsorption part 11, and air A2 for adsorption and desorption is made to flow from the heat recovery part 14 to the desorption part 13 through the heat storage part 12. A heater 4 is mounted on the upstream side of the desorption part 13. In such a constitution, the heat recovery part 14 recovers heat from the adsorbing and desorbing rotor 1 to air A2 for desorption to reduce the thermal dose of the heater 4, and at the same time, the preheating by the heat storage part 12 reduces the heat load on the adsorbing and desorbing rotor 1 in the desorption part 13. By the synergistic effect, the power consumption of the heater 4 is kept low, and at the same, high adsorption and desorption capacities are given, so that both energy saving and cost reduction can be realized in the adsorbing and desorbing device.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an adsorption / desorption device for adsorbing and desorbing gas components such as odorous gas and water vapor in the air.

[0002]

2. Description of the Related Art In recent years, in response to the increasing awareness of improving living environments, for example, in various factories, special wards of hospitals, at the time of perm at beauty salons, etc., not to mention, in high-concentration environments of odorous and harmful gases, Even in ordinary households considered to have a relatively low concentration environment, attempts have been widely made to purify the air in a living environment by removing odorous or harmful gases contained in the air. From the same viewpoint, air quality has been improved by dehumidification as part of air conditioning.

[0003] As one of the devices used for removing such gas components such as odorous gas, harmful gas or water vapor in the air, there is an adsorption / desorption device of a heating and regenerating type utilizing an adsorption / desorption effect of an adsorbent. . This adsorption / desorption device is composed of zeolite,
An adsorbent such as activated carbon or silica gel is provided. Air is passed through the adsorbent to remove gas components such as odorous gas and harmful gas and moisture and to be removed by the adsorbent to purify or reform the air. When the adsorbing ability of the adsorbent decreases with an increase in the adsorbing amount, the adsorbent is heated to desorb the adsorbed gas components and the like from the adsorbent to regenerate the adsorbing ability, thereby achieving a long-term regeneration. Thus, the air purifying function and the like are maintained.

As a specific structure of such a heating / reproducing adsorption / desorption device, for example, one adsorption / desorption rotor in which an adsorbent is carried on a disc having a honeycomb structure is provided, and the adsorption / desorption rotor is mounted on the adsorption / desorption rotor. From the rear side to the front side in the rotation direction, the "adsorption section", the "desorption section", and the "heat recovery section" are sequentially set, and the entire area of the adsorption / desorption rotor is rotated by rotating the adsorption / desorption rotor at a predetermined speed. Are sequentially configured to correspond to the “adsorbing section”, “desorption section”, and “heat recovery section”. Then, the air to be treated is purified by passing the air to be treated (that is, the indoor air to be treated) through the “adsorbing section” so that the gas components such as odorous gas are adsorbed and retained by the adsorbent and retained. On the other hand, desorption air (for example, using room air) is heated by a heater and supplied as hot air to the “removal section”, and the portion corresponding to the “removal section” of the suction / removal rotor is heated to be adsorbed on the section. The function of the adsorbent is regenerated by desorbing the retained gas component from the adsorbent to prepare for the next adsorption action.

Further, in this case, in order to suppress the power consumption of the heater, before the desorption air is supplied to the "removable portion", the air is disposed forward of the "removable portion" in the rotation direction of the suction / removal rotor. The heat is introduced into the “heat recovery section” set on the side, and the air is taken up by the section that maintains a high temperature by raising the temperature by the regeneration action of the “desorption section” of the adsorption / desorption rotor to remove the desorption air. By raising the temperature (that is, performing heat recovery), the heated desorption air is further heated by the heater and supplied to the "desorption section", thereby reducing the power consumption of the heater by the amount of heat recovery. I try to plan.

[0006]

By the way, in the adsorption / desorption device having the adsorption / desorption rotor of the heating / regenerating type, the desorption operation at the "desorption portion" is realized by using less heater power, thereby achieving energy saving. The performance can be improved.

To achieve this, (1) obtain high-temperature desorption air with less power consumption (ie, reduce the amount of heater heat required to raise the temperature of desorption air), and (2) absorb air. It is considered effective to preheat the desorption rotor and shift to the “desorption part” (that is, to reduce the required temperature increase width of the adsorption / desorption rotor in the “desorption part”). Is configured to recover the residual heat from the suction / desorption rotor side after passing through the “desorption section” in the “heat recovery section” to the desorption air side as described above. Such a method is the method described in (1) above. It is considered that the intended purpose can be achieved in terms of energy saving.

However, in the conventional adsorption / desorption apparatus, although "heat recovery" is performed as described above, this is not yet sufficient, and there is room for further improvement. For ()), no effective means has yet been proposed, and its development is being requested.

Therefore, the present invention relates to an adsorption / desorption device,
An object of the present invention is to realize an increase in adsorption / desorption capacity while minimizing an increase in power consumption.

[0015]

According to the present invention, the following functions and effects can be obtained by adopting such a configuration.

In the adsorption / desorption device according to the first invention of the present application, the adsorption unit 11 is provided with an adsorbent for adsorbing and desorbing a gas component in air, and the adsorption unit 11 is provided in a predetermined region in the rotation direction of the rotationally driven adsorption / desorption rotor 1. and sets, adsorbing unit 11 sequentially sets toward desorption unit 13 and the heat recovery section 14 forward in the rotational direction and the heat storage unit 12 in the rotational direction of the front side of, on the suction unit 11 the air to be treated a ₁ While allowing the gas to flow through the corresponding portion, the desorption air A ₂ sequentially flows from the heat recovery unit 14 to the heat storage unit 12 via the desorption unit 13,
On the upstream side of the desorption unit 13 includes a heating heater 4 of the desorption air A _2.

[0017] Therefore, in the adsorption-desorption apparatus according to the present invention, by flowing through the air to be treated A ₁ while rotating the desorption rotor 1 in a portion corresponding to the suction unit 11 of the suction desorption rotor 1, the odorous gas contained in the air to be treated a _1,
Gas components such as noxious gas or water vapor is adsorbed and collected on the adsorbent suction desorption rotor 1, cleaning or modification of該被process air A ₁ is performed.

The adsorption action of the gas component by the adsorption / desorption rotor 1 is performed while the adsorption / desorption rotor 1 is rotating, as each part of the adsorption / desorption rotor 1 rotates. It is performed continuously during the period from the side to the end side, and the amount of adsorption at each part gradually increases and approaches a saturated state, and accordingly, the adsorption capacity of each part gradually decreases. Then, each part of the adsorption / desorption rotor 1 that has absorbed the gas component to near the saturation state and has reduced its adsorption ability as described above moves from the adsorption part 11 to the heat storage part 12 side as the adsorption / desorption rotor 1 rotates. Then, the heat storage section 12 moves to the desorption section 13 side.

In the desorption section 13, the desorption air A ₂ heated by the heater 4 and turned into hot air flows through the respective sections of the suction / removal rotor 1 corresponding to the desorption section 13, whereby the respective sections are removed. Is heated by the heat exchange with the desorption air A _2, and the gas components adsorbed and held therein are sequentially desorbed from the adsorbent, whereby each part of the adsorption / desorption rotor 1 corresponding to the desorption section 13 In, the adsorption capacity is sequentially regenerated.

On the other hand, the desorption air A ₂ flows through each part of the adsorption / desorption rotor 1 corresponding to the heat recovery part 14 before being introduced into the desorption part 13 side. because it has a residual heat by heating the parts 13, dehydration wear air a ₂ is heated by heat exchange with the respective sites (i.e., heat recovery to desorption air a ₂ side), a high temperature state At the side of the desorption section 13, where it is further heated and heated by the heater 4 to produce high-temperature hot air.
3 flows through each part of the adsorption / desorption rotor 1.
Therefore, only the heat recovery amount in the heat recovery unit 14, so that the necessary heating amount of the heater 4 required for heating the desorption air A ₂ is reduced.

Further, the desorption air A after flowing through each part corresponding to the desorption section 13 of the adsorption / desorption rotor 1
No. ₂ contains a large amount of gas components, and its temperature is still kept at a high temperature.
2 and flows out through the corresponding portions of the adsorption / desorption rotor 1 and is discharged to the outside. However, while flowing through the respective portions, heat is transferred to the respective portions immediately before the transfer to the desorption section 13. This is replaced and preheated (that is, heat is recovered to the adsorption / desorption rotor 1 side). Accordingly, each part of the adsorption / desorption rotor 1 is preheated in the heat storage part 12 and moves to the next desorption part 13 in a state of being activated to some extent. The required temperature increase width of the desorption rotor 1, that is, the difference between the required desorption temperature and the preheating temperature is reduced.

[0022] As a result, according to the adsorption and desorption apparatus of the present invention, and it can reduce the heat quantity of the heat recovery amount corresponding heater 4 from adsorption-desorption rotor 1 side in the heat recovery unit 14 to the removable air A ₂ side As a synergistic effect of reducing the heating load on each part of the adsorption / desorption rotor 1 in the desorption section 13 by the preheating in the heat storage section 12, a high level of absorption while suppressing the power consumption of the heater 4 is achieved. The desorption capability can be exhibited, and both energy saving and cost reduction of the adsorption / desorption device can be achieved.

In the adsorption / desorption device according to the second invention of the present application, the adsorption / desorption device is provided with an adsorbent for adsorbing / desorbing a gas component in the air, and the adsorption section 11 is provided in a predetermined region in the rotation direction of the rotation driven adsorption / desorption rotor 1. At the same time, the heat storage unit 12 and the first heat recovery unit 1
5, the desorption section 13 and the second heat recovery section 16 are sequentially set forward in the rotational direction to allow the air A ₁ to flow through the portion corresponding to the suction section 11, while the desorption air A ₂ After flowing through the first heat recovery unit 15 and the second heat recovery unit 16 individually, and then through the desorption unit 13 to the heat storage unit 12 sequentially.
3 of heater 4 of the desorption air A ₂ is on the upstream side
It has.

[0024] Thus, in, by flow through the air to be treated A ₁ while rotating the desorption rotor 1 in a portion corresponding to the suction unit 11 of the suction desorption rotor 1 desorption apparatus of the invention, the odorous gas contained in the air to be treated a _1,
Gas components such as noxious gas or water vapor is adsorbed and collected on the adsorbent suction desorption rotor 1, cleaning or modification of該被process air A ₁ is performed.

The adsorption of the gas component by the adsorption / desorption rotor 1 is performed while the adsorption / desorption rotor 1 corresponds to the adsorption section 11, that is, each part of the adsorption / desorption rotor 1 rotates along with the rotation of the adsorption section 11. It is performed continuously during the period from the side to the end side, and the amount of adsorption at each part gradually increases and approaches a saturated state, and accordingly, the adsorption capacity of each part gradually decreases. Then, the respective parts of the adsorption / desorption rotor 1 which have adsorbed the gas components to near the saturation state and have reduced the adsorption ability as described above, move from the adsorption part 11 to the heat storage part 12 and the heat storage part 12 as the adsorption / desorption rotor 1 rotates. The process proceeds to the desorption section 13 through the heat recovery section 15 of the first section.

In the desorption section 13, the desorption air A ₂ heated by the heater 4 and turned into hot air flows through the respective sections of the suction / removal rotor 1 corresponding to the desorption section 13, whereby the respective sections are removed. Is heated by the heat exchange with the desorption air A _2, and the gas components adsorbed and held therein are sequentially desorbed from the adsorbent, whereby each part of the adsorption / desorption rotor 1 corresponding to the desorption section 13 In, the adsorption capacity is sequentially regenerated.

On the other hand, the desorption air A ₂ corresponds to each of the first heat recovery part 15 and the second heat recovery part 16 of the adsorption / desorption rotor 1 before being introduced to the desorption part 13 side. Of the first heat recovery unit 15 and the second heat recovery unit 16, the portions corresponding to the first heat recovery unit 15 remain due to the temperature rise in the desorption unit 13. Since each part has heat, and each part corresponding to the second heat recovery part 16 is heated by the preheating in the heat storage part 12 as described below, the desorption air A ₂ A part of them is formed by heat exchange with each part of the adsorption / desorption rotor 1 corresponding to the first heat recovery part 15, and another part is the adsorption / desorption corresponding to the second heat recovery part 16. The temperature is raised by heat exchange with each part of the rotor 1 (that is,
Heat recovery to desorption air A ₂ side), is introduced into the desorption unit 13 side at a high temperature, where it is further Atsushi Nobori by the heater 4 the adsorption-desorption corresponding to the desorption unit 13 as a high-temperature hot air It flows through each part of the rotor 1. Therefore,
Only the heat recovery amount in the first heat recovery unit 15 and the second heat recovery unit 16, so that the necessary heating amount of the heater 4 required for heating the desorption air A ₂ is reduced. In addition, the amount of heat recovery is equal to that of the first heat recovery unit 15 and the second heat recovery unit 15.
Since the heat recovery is performed in both of the heat recovery units 16, the amount of reduction in the required heating amount of the heater 4 increases as compared with the case where the heat recovery is performed only on one of these sides, for example. Is what you do.

Further, the desorption air A after flowing through each part of the suction / removal rotor 1 corresponding to the desorption section 13.
No. ₂ contains a large amount of gas components, and its temperature is still kept at a high temperature.
2 and flows out through the corresponding portions of the adsorption / desorption rotor 1 and is discharged to the outside. However, while flowing through the respective portions, heat is transferred to the respective portions immediately before the transfer to the desorption section 13. This is replaced and preheated (that is, heat is recovered to the adsorption / desorption rotor 1 side). Accordingly, each part of the adsorption / desorption rotor 1 is preheated in the heat storage part 12 and moves to the next desorption part 13 in a state of being activated to some extent. The required temperature increase width of the desorption rotor 1, that is, the difference between the required desorption temperature and the preheating temperature is reduced.

[0029] As a result, according to the adsorption and desorption apparatus of the present invention, from the adsorption-desorption rotor 1 side in both of the first heat recovery unit 15 and the second heat recovery unit 16 to the removable air A ₂ side The synergistic effect of the fact that the heating amount of the heater 4 can be reduced by the amount of heat recovery and that the heating load on each part of the adsorption / desorption rotor 1 in the desorption section 13 due to the preheating in the heat storage section 12 is reduced. The heater 4 can exhibit a high level of adsorption / desorption capability while keeping the power consumption of the heater 4 low, thereby achieving both energy saving and cost reduction of the adsorption / desorption device.

According to the adsorption / desorption device according to the third invention of the present application, the following specific effects can be obtained in addition to the effects described above or above. That is, in the present invention, in the adsorption / desorption device according to the first, second, or third invention,
Because the gas components contained in the air to be treated A ₁ is a mixed gas odor gas or toxic gas or odor gases and toxic gases, air cleaning is carried out efficiently by the adsorption and desorption apparatus, a comfortable living environment Realized reliably.

According to the adsorption / desorption device according to the fourth invention of the present application, the following specific effects can be obtained in addition to the effects described above or above. That is, in the present invention, in the adsorption / desorption device according to the first, second, or third invention,

The entire area of the suction section 11 faces the air passage 31 to be processed.
The total amount of air to be treated A ₁ is to flow through the respective portions of the adsorption-desorption rotor 1 corresponding thereto from the suction unit 11 through the.

[0066] Next, a description of the operation such as the adsorption and desorption apparatus Z ₂ according to this embodiment.

In the adsorption / desorption device Z ₂ , while the adsorption / desorption rotor 1 is continuously rotated at an extremely low speed, the first fan F ₁ is operated to convert the room air into the air to be treated A ₁ in the duct 5. by introducing the treated air passage 31, air to be treated a ₁ introduced into the treated air passage 31 runs through the portion corresponding to the suction unit 11 of the adsorption-desorption rotor 1 in the thickness direction thereof flows to the downstream side, during this flow, here gas components harmful gas such Toka odorous gas contained in the air to be treated a ₁ is and is adsorbed and collected by the adsorbent carried on the adsorption-desorption rotor 1 Will be retained. Therefore, the air that has flowed through the portion of the adsorption / desorption rotor 1 corresponding to the adsorption section 11 becomes clean treated air from which gas components have been removed as much as possible, and is returned to the room again. As a result, the indoor air is purified or reformed, and a comfortable living space is obtained.

The adsorbing / removing rotor 1 is sequentially rotated from one end (the side corresponding to the region line “Ld”) to the other end (the region line “Ld”) of the adsorbing section 11 as it rotates.
The gas components above are contained in the air to be treated A ₁ because it holds it adsorb and while moving toward the side) corresponding to a "gradually its adsorption amount increases it approaches saturation , The adsorption capacity is reduced, but the decrease in the adsorption capacity is recovered by the desorption operation in the desorption section 13.

[0069] That is, in the desorption air passage 32, the second fan F ₂ by the inlet 32a, respectively indoor air or the like from 32b side is delivered as the desorption air A _2. Of the desorption air A ₂ introduced into the desorption air passage 32 side, the from the inlet port 32a first
Introduced into the fourth chamber 2d side of the second chamber 3 flows through a portion corresponding to the second heat recovery section 16 of the adsorption / desorption rotor 1, and then flows into the fourth chamber 3d on the second chamber 3 side.
Through the third chamber 3c. In addition, the inlet 32b
Introduced into the second chamber 2b side of the first chamber 2 flows through a portion of the adsorption / desorption rotor 1 corresponding to the first heat recovery section 15 and then flows into the second chamber 3 side. It reaches the third chamber 3c via the second chamber 3b.

The desorption air A ₂ joined in the third chamber 3c is heated by the heater 4 to become high-temperature hot air, and flows through a portion corresponding to the desorption section 13 of the adsorption / desorption rotor 1 to flow therethrough. The part is heated and heated. Further, the desorption air A ₂ flowing through the desorption section 13 is inverted after moving from the third chamber 2c on the first chamber 2 side to the second chamber 2b, and the heat storage section 1 of the adsorption / desorption rotor 1 is rotated.
After flowing through the portion corresponding to No. 2, it is discharged outside through the outlet 32c.

In this case, a part of the desorption air A ₂ passes through the desorption section 13 of the suction / desorption rotor 1 in the second heat recovery section 16 and the second heat recovery section 16. By passing through the part that has moved to the recovery part 16 side (that is, the part that has been heated by the desorption action of the desorption part 13 and still maintains a high temperature), the temperature is raised by heat exchange with the part ( in other words, the primary heat recovery to desorption air a ₂ side). Another part of the desorption air A ₂ passes through the heat storage section 12 of the adsorption / desorption rotor 1 to the first heat recovery section 15 in the first heat recovery section 15. migration to have portions (i.e., portions preheated by the heat accumulation effect of the heat storage unit 12) by passing through a temperature is raised by heat exchange with the partial (i.e., secondary to desorption air a ₂ side Heat recovery). After being heated by the primary and secondary heat recovery, respectively, the desorption air A ₂ joined in the third chamber 3c of the second chamber 3 is further heated by the heater 4 to generate high-temperature hot air. By flowing through a part of the adsorption / desorption rotor 1 corresponding to the desorption part 13, the part is heated and the desorption action of the adsorbent at the part is promoted.

Further, the desorption air A ₂ after flowing through the portion corresponding to the desorption section 13 of the adsorption / desorption rotor 1 is:
In the first chamber 2, the air is inverted and flows through a portion of the adsorption / desorption rotor 1 corresponding to the heat storage portion 12. In this case, the desorption air A ₂ is generated at a portion corresponding to the desorption portion 13. Although the temperature is lowered by the heat exchange, the temperature is still high, so that it flows through the portion corresponding to the heat storage section 12 of the adsorption / desorption rotor 1, so that the adsorption / desorption rotor 1 is desorbed air. It is preheated by heat exchange with the a ₂ (i.e., heat recovery from the desorption air a ₂ to adsorption-desorption rotor 1 side), so that the transition to the desorption unit 13 side in the preheating state. The desorption air A ₂ flowing through the portion corresponding to the heat storage unit 12 is supplied to the outlet 32c.
Is discharged to the outdoors.

In _2, together with the included gas component of the process air A ₁ is adsorbed and removed by the adsorption-desorption rotor 1 in the adsorption unit 11, adsorption of the adsorption-desorption rotor 1 by desorption action in the desorption unit 13 By regenerating the capacity, a high level of air cleaning effect can be obtained. The above is the basic effect in the adsorption and desorption apparatus Z _2, but in which specific effects are obtained if the following in addition to the basic effects such in adsorption-desorption apparatus Z ₂ in this embodiment.

That is, in the adsorption / desorption device Z ₂ of this embodiment, the adsorption section 11 is set in a predetermined area in the rotation direction of the adsorption / desorption rotor 1, and the heat storage section is located on the front side in the rotation direction with respect to the adsorption section 11.

[0075] Therefore, paying attention to the desorption action of the above desorption unit 13, the above-mentioned desorption air A ₂ that is heated to the required temperature by the heater 4 and the first heat recovery section 15 and the second heat recovery unit each since it is introduced into the desorption unit 13 side in the preheating state in 16 both, for example, specific desorption air a ₂ introduced in non-preheat state near room temperature when raising the temperature to the required temperature by the heater 4 Then, the required temperature increase width becomes smaller, and the adsorption / desorption rotor 1 moves to the desorption section 13 side in a preheated state, so that the adsorption / desorption rotor 1 is in a non-preheated state near room temperature, for example.
The compared when raising the temperature to the required desorption temperature by the desorption air A _2, the thermal load is reduced by preheating component for the adsorption-desorption rotor 1.

[0076] These results, it is possible to exhibit a high level of adsorption and desorption capability while suppressing the power consumption of the heater 4, in which attained to achieve both the energy saving and low cost of the adsorption-desorption apparatus Z ₂ is there.

After treating ₂ with a decomposition catalyst, it can be directly refluxed into the room. According to such a configuration, since heat loss is suppressed, it is particularly suitable when indoor air conditioning is performed.
