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 harmful 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, it is thought that, in various factories, hospitals, beauty salons, etc., not only in environments with high concentrations of odorous and harmful gases, but also in environments with relatively low concentrations. In general households, it has been widely attempted to purify the air in a living environment by removing odorous gas or harmful gas 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 the adsorption / desorption device of the heating / regenerating type, for example, there is provided a single adsorption rotor in which an adsorbent is carried on a disc having a honeycomb structure, and the rotation direction is placed on the adsorption rotor. The suction section and the desorption section are sequentially set from the rear side to the front side, and the entire area of the suction rotor is sequentially rotated by rotating the suction rotor at a predetermined speed, so that the suction section and the suction section are sequentially set. It is configured to correspond to the “removable part”. 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, fresh air for desorption (for example, indoor air or outdoor air) is heated by a heater and supplied as hot air to the "desorption section", and a portion corresponding to the "desorption section" of the adsorption rotor is heated to heat the desorption section. The gas component adsorbed and held is desorbed from the adsorbent to regenerate the function of the adsorbent and prepare for the next adsorption action.

[0005]

By the way, in the adsorption / desorption apparatus provided with such a heating and regeneration type adsorption rotor, if the rotation speed of the adsorption rotor is increased to improve the desorption efficiency, sufficient gas is used. In order to regenerate the function of the adsorbent by desorbing the components from the adsorbent, the central angle of a portion (usually a portion obtained by dividing the adsorption rotor into a fan shape) corresponding to the "desorption portion" of the adsorption rotor is required. It is necessary to increase the amount, and the amount of hot air used for desorption regeneration (in other words, the amount of input heat) must be increased, which causes a problem of increasing running costs.

The present invention has been made in view of the above points, and in order to increase the rotation speed of the suction rotor and improve the desorption efficiency, the desorption section is divided into a plurality of desorption sections, and these divisions are set. The purpose of the present invention is to reduce the amount of hot air for desorption and to reduce running cost by sequentially desorbing and regenerating the desorption part.

The entire area of the suction section 11 faces the air passage 51 to be processed.
Treated whole amount of the air A ₁ flowing 1 has become possible to flow through each part of the adsorption rotor 1 corresponding to the suction unit 11.

As shown in FIGS. 3 to 5, for example, the catalyst 8 has a cylindrical honeycomb structure 8 made of stainless steel.
A catalyst (for example, an oxidation catalyst such as platinum or palladium) is supported at a central portion on the inlet side of 1 to form a catalyst honeycomb 81a, and the other portion is formed as a heat recovery honeycomb 81b.

In the catalyst 8, as shown in FIG. 5, the outlet air A ₃ coming out of the first splitting / desorbing section 12A is
The catalyst 8 is supplied to the heater 4 from the opposite side of the catalyst honeycomb 81a through the heat recovery honeycomb 81b.
In the process of passing through the catalyst honeycomb 81b, the outlet air A ₃ heated and heated in the above is decomposed and removed of harmful gas components contained in the outlet air A ₃ to become desorbed air A _2, and the heat recovery heat exchanger 7 It is to be sent to Accordingly, in the catalyst 8, the outlet air A ₃ (for example, the outlet air A ₃ at 400 ° C. at the inlet side) heated and raised by the heater 4 and flowing through the catalyst honeycomb 81a is cooled by the low-temperature outlet air flowing through the heat recovery honeycomb 81b. Heat exchange with A ₃ (eg, 60 ° C. outlet air A ₃ at the inlet) will cause a gradual temperature drop, so outlet air A ₃ is at a temperature sufficient to activate the catalyst. It is desirable that the distance down to the temperature of ° C. be the axial dimension of the catalyst honeycomb 81a.

If the catalyst 8 having the above structure is adopted,
Air A ₃ air A ₃ supplied to the heater 4 has left the heater 4
Therefore, the heating cost by the heater 4 can be reduced.

As shown in FIGS. 6 and 7, a catalyst (for example, an oxidation catalyst such as platinum, palladium or the like) is annularly formed in the center of the cylindrical honeycomb structure 81 made of stainless steel on the inlet side. To support the annular catalyst honeycomb 8

As shown in FIGS. 10 and 11, the regulating valve 6 is located at an appropriate position in the circulation path K, is made of a material having a different coefficient of thermal expansion, and has a pair of pipes whose ends are superposed. (That is, a large-diameter pipe 61 and a small-diameter pipe 62). For example, the large-diameter pipe 61 is made of iron, and the small-diameter pipe 62 is made of aluminum. In a cold state, the clearance C is formed therebetween, but the clearance C is lost during thermal expansion (that is, the large diameter pipe 62 is made large). The small-diameter pipe 62 is in close contact with the inner peripheral surface of the pipe 61). In this way, when the high-temperature air A ₃ (for example, 200 ° C.) is flowing (in other words, when the adsorption / desorption device is operating), as shown in FIG. Difference (ie,
Iron: 10.4 x 10-6, Aluminum: 23.1 x 10-
According to 6), the small-diameter pipe 62 comes into close contact with the large-diameter pipe 61 so as to form a single tubular body. At the end of the operation of the adsorption / desorption device, the low-temperature air A ₆ (for example, 20 ° C.) is supplied. When flowing through the circulation path K, a clearance C is formed between the large-diameter pipe 61 and the small-diameter pipe 62 due to the difference in the coefficient of thermal expansion as shown in FIG. Therefore, foreign substances X such as dirt and moisture existing in the circulation path K can be discharged from the clearance C to the outside. In the present embodiment, the clearance C is obtained by the following equation. Here, the inner diameter of the small diameter pipe 62 is set to 150 mm.

C = 150 × (200−20) × (23.1-10.4) × 10 −6 = 0.343 mm Next, the operation and effect of the adsorption / desorption device according to the present embodiment will be described.

In this adsorption / desorption device, while the adsorption rotor 1 is continuously rotated at an extremely low speed, the suction fan F ₁ is operated to introduce the room air as the air to be processed A _{1 into the} air passage 51 in the duct 5. By doing so, the air passage 51 to be treated

Is adsorbed and collected by the adsorbent carried on the substrate and held here. Therefore, the air that has flowed through the portion of the suction rotor 1 corresponding to the suction portion 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.

By the way, the suction rotor 1 is sequentially turned on one end side of the suction portion 11 (the region line Ld
Wherein since the holding adsorbed and this gas component contained in the air to be treated A ₁ while moving toward the other end side (the side corresponding to the area line La) from the side) corresponding to,
The adsorption amount gradually increases, and the adsorption capacity decreases as the amount approaches the saturated state. However, the decrease in the adsorption capacity is caused by the desorption section 12 (specifically, the first and second divided desorption sections 12A, 12A, It is recovered by the desorption action in 12B).

That is, the detachable fan F_TwoLed by the drive

That is, even accelerate the rotational speed of the adsorption rotor 1, divided set a plurality of divided desorption unit 12A, by sequentially flow through the desorption air A ₂ to 12B, the divided desorption unit 12A, 12B are sequentially desorption- The Rukoto. Therefore, without increasing the air volume of desorption air A _2, it will be able to secure a sufficient desorption efficiency and saving energy. Incidentally, in the case of the present embodiment, even if the rotation speed of the suction rotor 1 is doubled and the thickness of the suction rotor 1 is reduced to half, the same desorption / reproduction capability as in the related art can be secured.

The outlet air A ₃ coming out of the splitting / desorbing sections 12A and 12B is heated by the heater 4 and then turned on by the catalyst 8
