性質は非常に重要で、除湿機の能力を左右する。 In this type of dehumidifier, as shown in FIG. 1, a dehumidifying rotor is disposed astride a regeneration path in which heated air for regeneration, which has passed through a regeneration heater in the dehumidification path through which dehumidified air flows, flows counter-currently to the dehumidified air. The dehumidification rotor is driven and rotated by, for example, a belt, and the moisture absorbed by the filler from the dehumidified air passing through the rotor in the dehumidification path is recycled through the rotor in a countercurrent to the dehumidified air in the regeneration path. Regeneration of the filling material is carried out by expulsion into heated air, thus providing continuous dehumidification and regeneration. In a rotary dehumidifier having such a structure, the properties of the moisture absorbing material filled in the dehumidifying rotor are very important and influence the performance of the dehumidifier.

担体に担持してシート状の吸湿材にしてハニカム
構造を形成するものである。 Traditionally, two types of materials have been used for the dehumidifying rotor for rotary dehumidifiers. One is corrugated cardboard, which is made by impregnating asbestos paper, ceramic fiber, and nonwoven fabric with an absorbing liquid such as lithium chloride solution and drying them. The other method is to fill a cylindrical body with a solid moisture absorbent such as silica gel, activated alumina, or molecular sieve in its granular form, or to transfer the powder to a paper or cloth-like carrier. The material is supported on the substrate to form a sheet-like moisture absorbent material to form a honeycomb structure.

ものとなつてしまう。 However, these dehumidification rotors have a number of problems. First, in materials impregnated with moisture-absorbing liquid, due to the deliquescent nature of the moisture-absorbing agent, when used in high humidity, the material absorbs a large amount of moisture, which may cause the rotor to deform or the moisture-absorbing agent to flow off the rotor. There is. Therefore, it is necessary to refrain from using it in high humidity areas, and when stopping operation, it is necessary to take measures such as keeping it tightly covered so that it does not come into contact with the air. In addition, lithium chloride is highly corrosive, requiring the use of corrosion-resistant materials, which results in expensive equipment.

フタークーラーの必要性が生じてくる。 On the other hand, in the case of using a solid moisture absorbent, although there are no problems as mentioned above, there are also inherent problems. In the case of granular particles, the surface area in contact with air is small, so the adsorption speed is slow and efficiency is low. Further, the pressure loss is large, the cost of auxiliary power is increased, and since the air is vented in the circumferential direction of the rotor, there is a risk that the processing air and the regeneration air may be alternately or self-mixed, resulting in a decrease in dehumidification performance.
Further, it is considered that the disadvantages of fine powder supported on a carrier such as a fibrous sheet are that the processing is troublesome and that the thermal energy consumed during rotor regeneration is large due to the heat capacity of the carrier. In addition, solid moisture absorbers generally have a large heat of adsorption, which causes a significant drop in relative humidity due to an increase in the temperature of the treated air, which is disadvantageous for dehumidification and requires an aftercooler to cool the treated air. .

以上のように、回転式除湿機に用いる素材には
今のところ適当なものが見当らないのが現状であ
る。 As mentioned above, the current situation is that there is currently no suitable material for use in rotary dehumidifiers.

The BET surface area is 400 m 2 /g or more, and the pore diameter is 10 to 40 Å. The composition of the raw material borosilicate glass is that the SiO 2 content is 30 to 50% by weight,
It is preferable that the weight ratio of Na 2 O / B 2 O 2 is 0.11 to 0.33, and that it contains 5% or more of Al 2 O 3 as an additive, but it is not necessarily limited to this ratio depending on processing and usage conditions. . Acid treatment is usually 90-100

性の問題は皆無である。 The porous glass produced by the above method has an area of 400 m 2 /
It is essential that the adsorption surface area is at least 700 m 2 /g, preferably 700 to 900 m 2 /g, and the pore size distribution is in the range of 10 to 40 Å. The BET surface area is a value measured with Cantersorb manufactured by Quantachrome, Inc. in the United States. The equilibrium moisture adsorption amount of the obtained porous glass was 15% by weight at a relative humidity of 20%, 30% by weight at 50%, and 50% by weight at 70% (Shibata chemical moisture adsorption measurement device P-
850 at 25°C), and changes in moisture absorption relative to changes in relative humidity over a wide humidity range (i.e.,
Since the difference between the amount of moisture absorbed at RH 60% and that at RH 5% is large, it is extremely suitable as an element for a rotary dehumidifier that repeatedly adsorbs and regenerates moisture absorbing material depending on the relative humidity difference between the processing side and the regeneration side. In other words, the performance required of a dehumidifying material is such that the difference in adsorption amount between dehumidified air with RHB 50 to 60% and air with RH 5% during regeneration is superior in dehumidifying performance. In addition, the heat of adsorption is 670Kcal/Kg-H 2 O, which is smaller than conventional materials, so it has good dehumidification efficiency. In addition, since the amount of moisture absorbed is small at relative humidity of 5% or less, it is an energy-saving dehumidifying material that can be regenerated at relatively low temperatures, and is also advantageous when regenerated at high temperatures because it is heat resistant. moreover,
There are no deliquescent or corrosive problems that arise with lithium chloride, etc.

る。 The porous glass can be used in various forms, such as fibrous (cotton, paper, woven fabric, non-woven fabric), hollow tube, etc., depending on the usage conditions, but all of them have a large specific surface area and a high adsorption rate, so they can be used repeatedly. It is particularly advantageous for

再生熱エネルギーを節減することができる。 FIG. 2 shows the cylindrical body 7 of the dehumidifying rotor 1 shown in FIG. 1 filled with porous glass hollow tubes 8 according to the present invention cut to the axial length of the cylindrical body. Hollow tube has an outer diameter of 0.5~30mm, and an inner/outer diameter ratio of 0.3~0.8.
It is preferable to use one with an outer diameter of 2.0 and an inner/outer diameter ratio of 0.5. This allows ventilation only in the axial direction of the rotor and is cut off in the circumferential direction, thereby preventing mutual and self-mixing of processing air and regeneration air. In addition, since the molded body can be obtained using only porous glass, the heat capacity of the dehumidifying rotor is reduced.
Regenerative thermal energy can be saved.

In this case, it is desirable to provide a partition plate 9 in the circumferential direction to prevent ventilation in the circumferential direction of the dehumidifying rotor, and cover the porous glass cotton with a breathable cloth or the like to prevent the porous short glass fibers from scattering. is desirable. This method includes, for example, wrapping porous glass cotton with breathable cloth 10 to form a package-like dehumidifying element 11, and filling the gap between the partition plate 9 and the cylindrical body 7 with the package-like dehumidifying element 11. Alternatively, only the end surface of the rotor may be covered with breathable cloth.

しい。 Porous glass fibers have the advantage that they can be easily formed into sheet forms such as paper and cloth. When making paper, porous short glass fibers may be dispersed in water together with a thermoplastic polymer having a hydrophilic group such as polyvinyl alcohol, and paper may be made. In addition,
In order to improve formability, paper may be made by mixing valves. If it is to be made into cloth, it is sufficient to make it into a woven cloth or non-woven cloth at the raw material glass stage and then acid-treat it, which is advantageous in terms of cost because it requires fewer manufacturing steps. In order to fill the cylindrical body 7 with these porous glass sheets, there is a method of winding the porous glass sheet 13 while arranging spacers 12 at equal intervals as shown in FIG. Since the spacer 13 has the purpose of forming a gap between sheets and restricting ventilation in the circumferential direction, it is preferably made of a material that has no air permeability and a small heat capacity.

A sheet of porous glass having an area of 400 m 2 /g or more and a pore diameter of 10 to 40 Å may be processed into a corrugated board, and the corrugated board 14 may be rolled up to form a honeycomb structure.

In addition, since a molded body made of mostly porous glass is obtained, there is no excess heat capacity of the molding material that does not contribute to dehumidification, and the adsorption heat of the porous glass itself is small, resulting in high thermal efficiency. Furthermore, porous glass is not deliquescent or corrosive and is heat resistant, making operation and maintenance easy.
