Description

【０００１】
【発明の属する技術分野】
本発明は、吸着式除湿機に関するもので、特に低露点の空気を供給するために適したものである。
【０００２】
【従来の技術】
吸着式除湿機は冷凍式のものと比較して低露点の空気を供給するのに適しており、精密に空気条件を整える必要のある工場や食品への黴の発生の防止など、近年急速に用途が拡大している。特にシリカゲルやゼオライトなどの湿気吸着剤を担持したハニカム状ローターを使用した吸着式除湿機は構造が簡単で安価であるために広く普及している。
【０００３】
このようなハニカム状ローターを使用した吸着式除湿機は、少なくともハニカム状ローターを吸着ゾーンと脱着ゾーンとに分割するチャンバーやあるいはこれに加えて冷却ゾーンを加えたチャンバーを有している。このようなチャンバーの例として特許出願公開昭和５８年第１１９３２３号公報に開示されたものなどがある。
【０００４】
【発明が解決しようとする課題】
このようなチャンバーにあっては、脱着ゾーンに高温の空気を流すのであるが、その熱が冷却ゾーンや吸着ゾーンへ伝わると脱着ゾーンに流す空気の温度が下がりエネルギーの無駄が生じるだけでなく、冷却ゾーンや吸着ゾーンへ流れる空気の温度が上昇することによって吸着性能が下がるという問題がある。
【０００５】
このため脱着ゾーンを発泡シリコン樹脂やガラス繊維などの耐熱性のある断熱材で囲む必要があり、生産性の低いものであった。
【０００６】
本発明は極めて簡単な構造で断熱を施す必要がなく、生産性の高い吸着式除湿機を提供しようとするものである。
【０００７】
【課題を解決するための手段】
本件発明は以上のような課題を解決するため、ハニカム状ローターの端面に接する平面を有し、その反対面に吸着ゾーンを形成する吸着チャンバーと脱着ゾーンを形成する脱着チャンバーとを形成し、吸着チャンバーと脱着チャンバーとがそれぞれ離間した状態で形成されているチャンバーユニットを一対設け、一対のチャンバーユニットのそれぞれがハニカム状ローターの各端面に接するよう取り付けた。
【０００８】
【発明の実施の形態】
本発明の請求項１に記載の発明は、ハニカム状ローターの端面に接する平面を有し、その反対面に吸着ゾーンを形成する吸着チャンバーと脱着ゾーンを形成する脱着チャンバーとを有し、吸着チャンバーと脱着チャンバーとがそれぞれ離間した状態で形成されているチャンバーユニットを一対設け、一対のチャンバーユニットのそれぞれがハニカム状ローターの各端面に接するよう取り付けられたものであり、吸着チャンバーと脱着チャンバーとがそれぞれ離間しその間に熱の伝達が発生しないという作用を有する。
【０００９】
【実施例】
以下本発明の吸着式除湿機の実施例について図に沿って詳細に説明する。図１は図２のＡ−Ａ断面図、図３は図２のＢ−Ｂ断面図である。図２において１は除湿ローターであり、セラミックペーパーなどの無機繊維ペーパーをハニカム（蜂の巣）状に形成し、シリカゲルやゼオライトのような湿気吸着剤がハニカム状に形成された無機繊維ペーパー上に担持されている。また除湿ローター１はギヤドモーター（図示せず）より回転駆動される。
【００１０】
２は上部チャンバーユニットであり、例えばアルミニウムの鋳物やダイキャスト製である。上部チャンバーユニット２は吸着チャンバー３と脱着チャンバー４とパージチャンバー５とを有している。つまり上部チャンバーユニット２は除湿ローター１の端面に接する平面部６の上に吸着チャンバー３と脱着チャンバー４とパージチャンバー５とが形成され、図１、図３及び図４に示されるとおり、それぞれのチャンバーは互いに離間している。
【００１１】
また吸着チャンバー３と脱着チャンバー４とパージチャンバー５にはそれぞれ空気口７，８，９が設けられている。
【００１２】
１０は下部チャンバーユニットである。この下部チャンバーユニット１０は上部チャンバーユニット２と対称的な形状を有し、これにも底面図である図６及び図２のＢ−Ｂ断面図である図５に示すように吸着チャンバー１１と脱着チャンバー１２とパージチャンバー１３が平面部１４上に設けられている。そしてそれぞれのチャンバーは互いに離間している。
【００１３】
図６に示すように吸着チャンバー１１には空気口１５が設けられ、脱着チャンバー１２には空気口１６が設けられ、パージチャンバー１３には空気口１７が設けられている。
【００１４】
図８は図１のＣ−Ｃ断面図である。図８から判るように各ゾーン間のシール幅Ｗは、各ゾーン間で空気が漏れないようにするために十分な幅Ｗを確保する必要がある。この幅Ｗがあるためにこの幅Ｗに一致させて図８では吸着チャンバー３とパージチャンバー５との間を離間させることができる。厳密に表現すると、各チャンバーはシール幅Ｗから各チャンバーの壁の厚さを引いた長さだけ離間している。
【００１５】
しかもこうすることによって、図８で判るように各チャンバーの内面は平面部６の下端面に向かってストレートになる。従ってチャンバーユニットを作る際に鋳物の場合は中子が必要でなく、ダイキャストや合成樹脂の射出成型によっても容易に作ることができる。
【００１６】
また上部チャンバーユニット２の吸着チャンバー３と下部チャンバーユニット１０の吸着チャンバー１１は互いに除湿ローター１を介して対向するように形成され、上部チャンバーユニット２の脱着チャンバー４と下部チャンバーユニット１０の脱着チャンバー１２も互いに除湿ローター１を介して対向するように形成されている。そして上部チャンバーユニット２のパージチャンバー５と下部チャンバーユニット１０のパージチャンバー１３も互いに除湿ローター１を介して対向するように形成されている。
【００１７】
上部チャンバーユニット２の平面部６の３つの頂点それぞれにボルト孔１８，１９，２０が形成されており、下部チャンバーユニット１０の平面部１４の３つの頂点それぞれにボルト孔２１，２２，２３が形成されている。そしてボルト孔１８とボルト孔２２に１本の長いボルト（図示せず）が貫通して固定され、同様にボルト孔２０とボルト孔２３に１本の長いボルト、ボルト孔１８とボルト孔２１に１本の長いボルト貫通して固定され、これによって上部チャンバーユニット２と下部チャンバーユニット１０の間に除湿ローター１が挟まれた状態となる。この除湿ローター１を挟む圧力は、除湿ローター１が無理なく回転可能であって、かつ平面部６及び平面部１４と除湿ローター１の端面との間で空気の漏れが発生しない程度とする。
【００１８】
次に以上構成の本発明の吸着式除湿機の動作について説明する。除湿ローター１を駆動ベルト（図示せず）等を介し回転させながら、上部チャンバーユニット２の吸着ゾーン３内に空気口７より被処理空気を流す。すると図７に示すように被処理空気は除湿ローター１を通過し、乾燥空気となって除湿ローター１吸着ゾーン１１に入り、空気口１５より排出される。空気口１５にダクト等を取り付け、乾燥空気の供給先へ乾燥空気を送る。
【００１９】
被処理空気が除湿ローター１を通過する際に、被処理空気中の湿気が除湿ローター１の吸着剤に吸着され、吸着熱を発生する。このため下部チャンバーユニット１０の吸着ゾーン１１を通過する乾燥空気の温度は上昇している。図５に示すように吸着ゾーン１１はパージゾーン１３と離間しているため、吸着ゾーン１１の熱はパージゾーン１３へ伝わることがない。
【００２０】
除湿ローター１に吸着された湿気を除去するために、下部チャンバーユニット１０の脱着ゾーン１２に温度１００℃〜１５０℃程度の熱風を送る。するとこの熱風が除湿ローター１を通過する間に除湿ローター１に吸着された湿気は脱着され、上部チャンバーユニット２の脱着ゾーン４を多湿空気が通過する。
【００２１】
そして上部チャンバーユニット２のパージゾーン５から空気を送ると空気は除湿ローター１を通過する。この除湿ローター１の通過中に脱着空気によって温度の上がった除湿ローター１が冷却されるとともに、下部チャンバーユニット１０のパージゾーン１３に入る空気の温度が上昇する。
【００２２】
パージゾーン１３に入る空気の温度が上昇しているため、ここを出た空気をさらにヒーター（図示せず）によって加熱し、脱着ゾーン１２に入れるようにするとエネルギーの回収を行うことができる。
【００２３】
以上の実施例では上部チャンバーユニットも下部チャンバーユニットも吸着ゾーン、脱着ゾーン、パージゾーンを設ける例を示したが、上部チャンバーユニット及び下部チャンバーユニットともパージゾーンを設けず、吸着ゾーン、脱着ゾーンのみでもよい。
【００２４】
【発明の効果】
本発明の吸着式除湿機は上記の如く構成したので、上部チャンバーユニットも下部チャンバーユニットも吸着ゾーン、脱着ゾーン、パージゾーンが各々独立し互いに離間しているため、ゾーン間の熱の移動がなく、断熱を施す必要がない。
【００２５】
また吸着ゾーン、脱着ゾーン、パージゾーンが各々独立し互いに離間しているため、各ゾーンの間のシール幅Ｗを十分に大きく取ることができ、シール効果を十分確保することができる。
【００２６】
さらに本発明の吸着式除湿機は吸着ローターに接して気密をはかる平面部と、吸着ゾーン、脱着ゾーン、パージゾーンとを一体に作ることができるため、鋳物やダイキャストあるいは合成樹脂の成型によって容易に量産することができる。

BACKGROUND OF THE INVENTION
The present invention relates to an adsorption type dehumidifier, and is particularly suitable for supplying low dew point air.
[0002]
[Prior art]
Adsorption-type dehumidifiers are suitable for supplying air with a low dew point compared to refrigeration-type dehumidifiers, and in recent years, such as the prevention of soot generation in factories and foods that require precise air conditions. Applications are expanding. In particular, an adsorption type dehumidifier using a honeycomb rotor carrying a moisture adsorbent such as silica gel or zeolite is widely used because of its simple structure and low cost.
[0003]
The adsorption type dehumidifier using such a honeycomb-shaped rotor has at least a chamber for dividing the honeycomb-shaped rotor into an adsorption zone and a desorption zone, or a chamber to which a cooling zone is added. An example of such a chamber is disclosed in Japanese Patent Application Publication No. 119323.
[0004]
[Problems to be solved by the invention]
In such a chamber, high-temperature air flows through the desorption zone, but when the heat is transmitted to the cooling zone or the adsorption zone, the temperature of the air flowing through the desorption zone decreases, resulting in wasted energy. There is a problem in that the adsorption performance is lowered due to an increase in the temperature of the air flowing into the cooling zone or the adsorption zone.
[0005]
For this reason, it is necessary to surround the desorption zone with a heat-resistant heat insulating material such as foamed silicon resin or glass fiber, and the productivity is low.
[0006]
The present invention is intended to provide an adsorption type dehumidifier with a very simple structure that does not require heat insulation and has high productivity.
[0007]
[Means for Solving the Problems]
In order to solve the above-described problems, the present invention has a flat surface in contact with the end face of the honeycomb-shaped rotor, and forms an adsorption chamber that forms an adsorption zone and a desorption chamber that forms a desorption zone on the opposite surface, A pair of chamber units formed in a state where the chamber and the desorption chamber were separated from each other were provided, and each of the pair of chamber units was attached so as to be in contact with each end face of the honeycomb-shaped rotor.
[0008]
DETAILED DESCRIPTION OF THE INVENTION
The invention according to claim 1 of the present invention has a flat surface in contact with the end face of the honeycomb-shaped rotor, and has an adsorption chamber that forms an adsorption zone and a desorption chamber that forms a desorption zone on the opposite surface, A pair of chamber units formed in a state where the separation chamber and the desorption chamber are separated from each other are attached, and each of the pair of chamber units is attached so as to be in contact with each end face of the honeycomb-shaped rotor. They have the effect that they are spaced apart and no heat transfer occurs between them.
[0009]
【Example】
Embodiments of the adsorption dehumidifier of the present invention will be described in detail below with reference to the drawings. 1 is a cross-sectional view taken along line AA in FIG. 2, and FIG. 3 is a cross-sectional view taken along line BB in FIG. In FIG. 2, reference numeral 1 denotes a dehumidification rotor, in which inorganic fiber paper such as ceramic paper is formed in a honeycomb (honeycomb) shape, and a moisture adsorbent such as silica gel or zeolite is supported on the inorganic fiber paper formed in the honeycomb shape. ing. The dehumidifying rotor 1 is driven to rotate by a geared motor (not shown).
[0010]
Reference numeral 2 denotes an upper chamber unit made of, for example, aluminum casting or die casting. The upper chamber unit 2 has an adsorption chamber 3, a desorption chamber 4, and a purge chamber 5. That is, the upper chamber unit 2 includes an adsorption chamber 3, a desorption chamber 4, and a purge chamber 5 formed on a flat portion 6 in contact with the end surface of the dehumidification rotor 1. As shown in FIGS. 1, 3, and 4, The chambers are spaced apart from each other.
[0011]
Further, air ports 7, 8, and 9 are provided in the adsorption chamber 3, the desorption chamber 4, and the purge chamber 5, respectively.
[0012]
Reference numeral 10 denotes a lower chamber unit. The lower chamber unit 10 has a symmetric shape with the upper chamber unit 2 and is also attached to and detached from the adsorption chamber 11 as shown in FIG. 6 which is a bottom view and FIG. 5 which is a BB sectional view of FIG. A chamber 12 and a purge chamber 13 are provided on the flat portion 14. Each chamber is separated from each other.
[0013]
As shown in FIG. 6, the adsorption chamber 11 has an air port 15, the desorption chamber 12 has an air port 16, and the purge chamber 13 has an air port 17.
[0014]
8 is a cross-sectional view taken along the line CC of FIG. As can be seen from FIG. 8, the seal width W between the zones needs to ensure a sufficient width W so that air does not leak between the zones. Since there is this width W, the adsorption chamber 3 and the purge chamber 5 can be separated from each other in FIG. Strictly speaking, the chambers are separated by a length obtained by subtracting the thickness of the wall of each chamber from the seal width W.
[0015]
In addition, by doing so, the inner surface of each chamber becomes straight toward the lower end surface of the flat portion 6 as can be seen in FIG. Therefore, when casting the chamber unit, a core is not necessary in the case of casting, and it can be easily made by die casting or injection molding of synthetic resin.
[0016]
Further, the adsorption chamber 3 of the upper chamber unit 2 and the adsorption chamber 11 of the lower chamber unit 10 are formed so as to face each other via the dehumidification rotor 1, and the desorption chamber 4 of the upper chamber unit 2 and the desorption chamber 12 of the lower chamber unit 10 are formed. Are formed so as to face each other via the dehumidifying rotor 1. The purge chamber 5 of the upper chamber unit 2 and the purge chamber 13 of the lower chamber unit 10 are also formed so as to face each other via the dehumidifying rotor 1.
[0017]
Bolt holes 18, 19 and 20 are formed at the three apexes of the plane portion 6 of the upper chamber unit 2, and bolt holes 21, 22, and 23 are formed at the three apexes of the plane portion 14 of the lower chamber unit 10, respectively. Has been. Then, one long bolt (not shown) passes through and is fixed to the bolt hole 18 and the bolt hole 22. Similarly, one long bolt is inserted into the bolt hole 20 and the bolt hole 23. One long bolt penetrates and is fixed, so that the dehumidification rotor 1 is sandwiched between the upper chamber unit 2 and the lower chamber unit 10. The pressure sandwiching the dehumidifying rotor 1 is set such that the dehumidifying rotor 1 can be rotated without difficulty and no air leakage occurs between the flat surface portion 6 and the flat surface portion 14 and the end surface of the dehumidifying rotor 1.
[0018]
Next, the operation of the adsorption dehumidifier of the present invention having the above configuration will be described. While rotating the dehumidifying rotor 1 via a drive belt (not shown) or the like, the air to be treated is caused to flow from the air port 7 into the adsorption zone 3 of the upper chamber unit 2. Then, as shown in FIG. 7, the air to be treated passes through the dehumidification rotor 1, becomes dry air, enters the dehumidification rotor 1 adsorption zone 11, and is discharged from the air port 15. A duct or the like is attached to the air port 15, and the dry air is sent to the supply destination of the dry air.
[0019]
When the air to be treated passes through the dehumidifying rotor 1, the moisture in the air to be treated is adsorbed by the adsorbent of the dehumidifying rotor 1 and generates heat of adsorption. For this reason, the temperature of the dry air passing through the adsorption zone 11 of the lower chamber unit 10 is rising. As shown in FIG. 5, since the adsorption zone 11 is separated from the purge zone 13, the heat of the adsorption zone 11 is not transmitted to the purge zone 13.
[0020]
In order to remove the moisture adsorbed by the dehumidifying rotor 1, hot air having a temperature of about 100 ° C. to 150 ° C. is sent to the desorption zone 12 of the lower chamber unit 10. Then, while the hot air passes through the dehumidification rotor 1, the moisture adsorbed on the dehumidification rotor 1 is desorbed, and the humid air passes through the desorption zone 4 of the upper chamber unit 2.
[0021]
When air is sent from the purge zone 5 of the upper chamber unit 2, the air passes through the dehumidifying rotor 1. While the dehumidification rotor 1 is passing, the dehumidification rotor 1 whose temperature has been increased by the desorption air is cooled, and the temperature of the air entering the purge zone 13 of the lower chamber unit 10 is increased.
[0022]
Since the temperature of the air entering the purge zone 13 is rising, energy can be recovered by further heating the air that has exited here with a heater (not shown) and entering the desorption zone 12.
[0023]
In the above embodiment, the upper chamber unit and the lower chamber unit are provided with the adsorption zone, the desorption zone, and the purge zone. However, neither the upper chamber unit nor the lower chamber unit is provided with the purge zone, and only the adsorption zone and the desorption zone are provided. Good.
[0024]
【The invention's effect】
Since the adsorption dehumidifier of the present invention is configured as described above, the upper chamber unit and the lower chamber unit are independent from each other in the adsorption zone, the desorption zone, and the purge zone, so there is no heat transfer between the zones. There is no need for thermal insulation.
[0025]
Further, since the adsorption zone, the desorption zone, and the purge zone are each independently separated from each other, the seal width W between the zones can be made sufficiently large, and a sufficient sealing effect can be ensured.
[0026]
Furthermore, the adsorption type dehumidifier of the present invention can make a flat part that comes into contact with the adsorption rotor to be airtight and an adsorption zone, a desorption zone, and a purge zone, so that it can be easily formed by casting, die casting or synthetic resin molding. Can be mass-produced.
