現今執行連續式除濕的除濕裝置,大多採取同時執行利 用除濕劑施行被處理空氣的除濕、及已吸附水分之該除濕 劑的再生。所以,該除濕裝置所使用的該除濕劑中,不僅 要求將被處理空氣中之水分吸附去除的性能(以下記為「吸 濕性能」),尚要求將已吸附的水分進行脫吸的優越性能(以 下記為「脫濕性能」)。 該吸附性能與該脫濕性能二者均優越的除濕劑有如矽 膠,一般廣泛地使用為工業用除濕裝置的除濕劑。 但是,矽膠在絕對濕度較高的空氣中,雖將發揮優越的 吸濕性能,但是在絕對濕度較低的空氣中,卻幾乎未吸附 水分,並未發揮吸濕性能。所以,例如在絕對濕度較低的 冬季中,在室内將洗滌物乾燥時所使用的除濕機用除濕 劑,便無法使用石夕膠。 可吸附絕對濕度較低之空氣中的水分之物質,已知有如 沸石。該沸石有如:Y型沸石、X型沸石及A型沸石,該等 之中,Y型沸石在相較X型沸石或A型沸石之下,因為可 在低溫中進行水分的脫吸,因而可認為最適於使用為連續 執行除濕的除濕裝置用除濕劑。 5 312XP/發明說明書(補件)/94- ] 0/941丨9561In the dehumidifying apparatus which performs continuous dehumidification, it is often carried out to simultaneously perform dehumidification using a dehumidifying agent to perform dehumidification of the air to be treated, and regeneration of the dehumidifying agent which has adsorbed moisture. Therefore, in the desiccant used in the dehumidifier, not only the performance of adsorbing and removing moisture in the air to be treated (hereinafter referred to as "hygroscopic property") but also the superior performance of desorbing the adsorbed water is required. (The following is referred to as "dehumidification performance"). The dehumidifying agent which is excellent in both the adsorption performance and the dehumidifying performance is, for example, a silicone rubber, and is generally widely used as a dehumidifying agent for an industrial dehumidifying device. However, tannin extract has excellent moisture absorption performance in air with high absolute humidity, but in the air with low absolute humidity, it hardly adsorbs moisture and does not exert moisture absorption performance. Therefore, for example, in the winter when the absolute humidity is low, the dehumidifier for the dehumidifier used when the laundry is dried indoors cannot be used. A substance which can adsorb moisture in air having a low absolute humidity is known as a zeolite. The zeolite is, for example, a Y-type zeolite, an X-type zeolite, and a type A zeolite. Among them, the Y-type zeolite is lower than the X-type zeolite or the A-type zeolite because it can desorb moisture at a low temperature. It is considered to be most suitable for use as a desiccant for dehumidifying devices that continuously perform dehumidification. 5 312XP / invention manual (supplement) /94- ] 0/941丨9561

The zeolite of the cerium type exhibits superior moisture absorption performance even in a low-humidity air at a moisture absorption rate. However, in the case where the desiccene type zeolite has insufficient dehumidification performance, in order to dehumidify by heating, the sodium cerium type zeolite can be regenerated, and a large amount of heat energy is required, so that an increase problem occurs. . Therefore, since the self-study, the sodium ion of the sodium cerium type zeolite is exchanged for other cations, and the enthalpy of the sorption and desorption performance of the cerium type zeolite can be adjusted. For example, Japanese Patent Laid-Open Publication No. 2000-1995 discloses a cerium type zeolite in which the sodium cerium type zeolite is ion-exchanged with a metal other than sodium. SUMMARY OF THE INVENTION However, when an ion-exchanged zeolite is applied by using a metal ion other than the sodium, the dehumidification performance is gradually lower than that of the sodium-yttrium-type zeolite. The problem occurred. Therefore, an object of the present invention is to provide a moisture retention performance (hereinafter referred to as "repetitive durability") when the desorption of moisture is exhibited even in an absolute air, which exhibits superior moisture absorption performance and desorption performance. In order to solve the problems of the above-mentioned conventional techniques, the inventors of the present invention have found that the specific physical properties of the sodium strontium type zeolite are set to 312 ΧΡ / invention specification (supplement) / 94. -10/941 ] 9561 The zeolite acid is faster than this. The specific dehumidification operation cost, the performance of the dehumidification performance is superior to that of the ion treatment of the 2 3 9 1 5 6 , but the reduced humidity is low, and the repetition is the “dry and wet intrusion study setting range, 6 1364322, the dehumidification performance of the sodium γ-type zeolite is improved, and the moisture absorption performance and the dehumidification performance are well balanced, and the present invention is completed. In other words, the desiccant provided by the invention (1) is S i 0 . 2 / A 12 0 3 Y-type zeolite having a molar ratio of 4.0 to 6.0, a Na 2 〇 / Al 2 〇 3 molar ratio of 0.5 to 1.0, and an average particle diameter of 3 / / m or less. Further, the present invention (2) The dehumidifying member is provided with a S i 0 2 /A 12 0 3 molar ratio of 4.0 to 6.0, a Na 2 〇/Al 2 〇 3 molar ratio of 0.5 to 1.0, and an average particle diameter of 3 μm or less. Y zeolite is supported on a carrier.
本發明的除濕劑與除濕用構件,因為吸濕性能與脫濕性 能的均衡佳,且乾濕重複耐久性亦優越,因而可將絕對濕 度較低的空氣中之水分良好地去除,且亦可降低營運成本。 【實施方式】 本發明之除濕劑係具有一般通稱Y型沸石的骨架構造, 且酸點的離子對為鈉離子之Y型沸石。此外,該Y型沸石 係可依一般式(1 ) X N a 2 0 · A 1 2 0 3 · y S i Ο 2 · z Η 2 Ο (1) 表示。該一般式(1 )中,x値(即N a 2 Ο / A 12 0 a莫耳比)係 0 . 5〜1 · 0,最好0. 6 ~ 0 . 9。該X値若未滿0 . 5,則因為水分 的吸附能力偏低,因此無法將絕對濕度較低的空氣中之水 分充分地去除,反之,若超過1 . 0,則因為較難脫濕,因 而為將該Y型沸石所吸附的水分進行脫吸,所需要的熱能 量(以下記為「脫濕能量」)便將增加。此外,y値(即 S i 0 2 / A 1 2 0 3 莫耳比)係 4 . 0 ~ 6 · 0,最好 4 . 0 ~ 5 . 5。該 y 値若 未滿4. 0,因為較難脫濕,因此脫濕能量將增加,反之, 7 312XP/發明說明書(補件)/94-10/94119561 1364322 若超過6. Ο,因為水分的吸附能力偏低,因而無法將絕對 濕度較低的空氣中之水分充分去除。 另外,沸石屬於Υ型沸石之情況,可藉由施行X射線繞 射分析所獲得之繞射圖案而進行確認。 該Υ型沸石的平均粒徑係3 y m以下,最好0 . 8 ~ 2. Ο V m。The dehumidifying agent and the dehumidifying member of the present invention have excellent balance between moisture absorption performance and dehumidifying performance, and excellent dry-wet repeat durability, so that moisture in the air having a low absolute humidity can be well removed, and Reduce operating costs. [Embodiment] The desiccant of the present invention has a skeleton structure generally called Y-type zeolite, and the ion pair of the acid point is a Y-type zeolite of sodium ion. Further, the Y-type zeolite can be represented by the general formula (1) X N a 2 0 · A 1 2 0 3 · y S i Ο 2 · z Η 2 Ο (1). In the general formula (1), x 値 (ie, N a 2 Ο / A 12 0 a molar ratio) is 0.5 to 1 · 0, preferably 0. 6 to 0.9. If the X 未 is less than 0.5, the moisture in the air having a low absolute humidity cannot be sufficiently removed, and if it is more than 1.0, the X 无法 is difficult to dehumidify. Therefore, the heat energy (hereinafter referred to as "dehumidification energy") required for desorption of the moisture adsorbed by the Y-type zeolite will increase. Further, y 値 (ie, S i 0 2 / A 1 2 0 3 molar ratio) is 4. 0 ~ 6 · 0, preferably 4. 0 ~ 5. 5 . If the y 未 is less than 4.0, the dehumidification energy will increase because it is more difficult to dehumidify. Otherwise, 7 312XP/invention specification (supplement)/94-10/94119561 1364322 exceeds 6. Ο, because of moisture The adsorption capacity is low, so that the moisture in the air with low absolute humidity cannot be sufficiently removed. Further, in the case where the zeolite is a quinoid type zeolite, it can be confirmed by performing a diffraction pattern obtained by X-ray diffraction analysis. The cerium type zeolite has an average particle diameter of 3 y m or less, preferably 0.8 to 2. Ο V m.
若該平均粒徑超過3 // m,因為較難脫濕,因而為將該Y型 沸石再生便需要較多的脫濕能量。即便N a 2 0 / A 12 0 3莫耳比 與Si〇2/Al2〇3莫耳比為相同程度的鈉Y型沸石,仍將依平 均粒徑的不同,而使脫濕能量有大幅差異。例如平均粒徑 3 " m者在相較於平均粒徑5 // m者之下,脫濕能量大概少 2 0%程度。 另外,在本發明中,所謂「脫濕能量j係指針對該Y型 沸石所吸附的水1 g,從該Y型沸石中進行脫濕所需要的熱 能量。而該脫濕能量係依下述方法進行求取。(i )首先,將 該Y型沸石在5 0 0 °C的乾燥機中,施行2小時乾燥。然後, 將該沸石從乾燥機中取出,並在放入乾燥劑的乾燥皿中, 將該沸石冷卻至2 5 °C。然後,將該沸石放入稱量瓶中,並 將該稱量瓶封閉,再利用秤進行秤量,並測定該沸石乾燥 時的重量(乾燥重量X ( g ))。( i i )將乾燥後的該沸石,在經 控制為2 5 °C、9 0 % R Η的乾燥皿中,放置4 8小時。然後,將 該沸石放入稱量瓶中,並將該稱量瓶封閉,利用秤進行秤 量,測定該沸石吸濕時的重量(吸濕重量Y ( g ) )。( i i i )然 後,將吸濕重量Y値減掉乾燥重量X値,而求取該沸石的 飽和吸附水分量。(i ν)其次,稱取吸濕後的該沸石2 0 . 0 mg, 8 312XP/發明說明書(補 ffi/94-10/94 〗19561 1364322 使用微差掃瞄熱量計(D S C ),測定從吸濕後的該沸石中將水 分脫濕時所需要的熱能量(Z ( J ) )。( v )根據下式(2 ),計算 出脫濕能量(J / g )。 脫濕能量= (ZxX)/{0· 02x(Y-X) } (2)If the average particle diameter exceeds 3 // m, since it is difficult to dehumidify, it is necessary to regenerate the Y-type zeolite to require a large amount of dehumidification energy. Even if the Na 2 0 / A 12 0 3 molar ratio is the same as that of the Si〇2/Al2〇3 molar ratio, the desorption energy will be greatly different depending on the average particle size. . For example, the average particle size 3 " m is about 20% less than the average particle size of 5 // m. Further, in the present invention, the "dehumidification energy j" is a thermal energy required to dehumidify 1 g of water adsorbed to the Y-type zeolite from the Y-type zeolite. The method is determined. (i) First, the Y-type zeolite is dried in a dryer at 500 ° C for 2 hours. Then, the zeolite is taken out from the dryer and placed in a desiccant. In a drying dish, the zeolite was cooled to 25 ° C. Then, the zeolite was placed in a weighing bottle, and the weighing bottle was closed, weighed by a weigher, and the weight of the zeolite was measured (dry) Weight X ( g )). ( ii ) The dried zeolite was placed in a drying dish controlled to 25 ° C, 90% R 4 for 48 hours. Then, the zeolite was weighed. In the bottle, the weighing bottle is closed, weighed by a weigher, and the weight (hygroscopic weight Y (g)) of the zeolite is measured. (iii) Then, the moisture absorption weight Y値 is reduced by the dry weight X値, and the saturated adsorbed moisture content of the zeolite is obtained. (i ν) Next, the zeolite after absorption is weighed 20.0 mg, 8 31 2XP/Invention Manual (Supplement ffi/94-10/94) 19561 1364322 Using a differential scanning calorimeter (DSC) to determine the thermal energy required to dehumidify moisture from the zeolite after moisture absorption (Z (J )) (v) Calculate the dehumidification energy (J / g) according to the following formula (2). Dehumidification energy = (ZxX) / {0 · 02x (YX) } (2)
因為該Υ型沸石的乾濕重複耐久性優越,因此將延長當 作除濕劑用時的壽命,因而將可降低營運成本。另外,該 Υ型沸石的乾濕重複耐久性係藉由在乾濕重複試驗前與試 驗後,測定該Υ型沸石的吸濕速度便可掌握,當該乾濕重 複試驗前的吸濕速度、與試驗後的吸濕速度無變化的情況 時,便判斷乾濕重複耐久性屬良好狀態。此外,本發明中, 所謂「該乾濕重複試驗」係指將該Υ型沸石在8 0 0 °C中施 行1 0分鐘加熱後,再於經放入乾燥劑的乾燥皿中,冷卻至 2 5 °C,接著再於2 5 °C、5 0 % R Η的乾燥皿中放置1 0分鐘,並 重複此操作1 0 0次的試驗。 該Υ型沸石係例如將N a 2 0 / A 1 2 0 3莫耳比與S i 0 2 / A 1 2 0 3莫 耳比在上述範圍内的鈉Y型沸石,利用乾式粉碎、濕式粉 碎等常法施行粉碎,並配合需要到用篩分等常法進行分級 便可獲得。 本發明的Y型沸石係藉由Na2〇/Al2〇3莫耳比、Si〇2/Al2〇3 莫耳比及平均粒徑在上述範圍内,便可具有將絕對濕度較 低之空氣中的水分吸附所需要的吸濕性能,且再生時的脫 濕能量較少。所以,該Y型沸石的吸濕性能與脫濕性能的 均衡佳。 依此,藉由將乾濕重複财久性優越的納Y型沸石之特定 9 3 ] 2XP/發明說明書(補件)/94- ] 0/94119561 1364322 物性,設定於特定範圍内,便可提供即便在絕對濕度較低 的空氣中,仍可發揮優越的除濕性能與脫濕性能,且乾濕 重複财久性優越的除濕劑。Since the cerium type zeolite has excellent dry-wet repeat durability, it will prolong the life when used as a dehumidifying agent, and thus it will reduce operating costs. In addition, the dry-wet repeat durability of the cerium-type zeolite can be grasped by measuring the moisture absorption rate of the cerium-type zeolite before and after the dry-wet repeat test, and the moisture absorption rate before the dry-wet repeat test, When there was no change in the moisture absorption rate after the test, it was judged that the dry-wet repeat durability was in a good state. Further, in the present invention, the "dry-wet repeat test" means that the cerium-type zeolite is heated at 80 ° C for 10 minutes, and then cooled to 2 in a drying dish in which a desiccant is placed. 5 ° C, then placed in a drying dish at 25 ° C, 50% R Η for 10 minutes, and repeat the test of this operation 100 times. The cerium type zeolite is, for example, a sodium Y zeolite having a Na 2 0 / A 1 2 3 3 molar ratio and a S i 0 2 / A 1 2 3 molar ratio in the above range, using dry pulverization, wet type It can be obtained by pulverizing and other common methods, and it can be obtained by grading according to the usual method such as sieving. The Y-type zeolite of the present invention has a Na2〇/Al2〇3 molar ratio, a Si〇2/Al2〇3 molar ratio and an average particle diameter within the above range, and can have an air having a lower absolute humidity. The moisture absorption performance required for moisture adsorption is small, and the dehumidification energy at the time of regeneration is small. Therefore, the Y-type zeolite has a good balance between moisture absorption performance and dehumidification performance. According to this, by setting the physical properties of the specific Y 3 zeolite 2, the invention specification (supplement)/94-] 0/94119561 1364322 of the nano-Y zeolite having superior wet and dry repeatability, it can be provided within a specific range. Even in the air with low absolute humidity, it can exert superior dehumidification performance and dehumidification performance, and the desiccant is excellent in dry and wet repeating.
