The present invention aims to improve the laminated structure of the hygroscopic-agent-impregnated exchanging member which heretofore tended to collapse easily and to dis-integrate so that even when the member becomes moist due to the hygroscopic agent impregnated therein, the form and shape thereof can be maintained solid and firm by using a base paper made by mixing synthetic pulp having water-repellent and thermo-plastic properties with fiber basic material and further by coating the above mentioned mixed paper with abrasion-resistant in the end face of the exchanging member.
The present invention aims to improve the laminated structure of the hygroscopic-agent-impregnated exchanging member which heretofore tended to collapse easily and to dis-integrate so that even when the member becomes moist due to the hygroscopic agent impregnated therein, the form and shape thereof can be maintained solid and firm by using a base paper made by mixing synthetic pulp having water-repellent and thermo-plastic properties with fiber basic material and further by coating the above mentioned mixed paper with abrasion-resistant in the end face of the exchanging member.
Description
~44~8 This invention relates to an exchanging member for heat and/or moisture and, more particularly, to an exchanging member of which form and shape can be maintained solid and firm even when such a member is subjected to moisture by the hygroscopic agent impregnated therein.
In the prior art, there has been provided the moisture exchange for a rotary dehumidifier as this type of exchanger. In the moisture-exchanger of the above mentioned type, the basic paper usually made with asbestos fiber is corrugated, then laminated to form a so-called asbestos fiber lamination and impregnated with a hygroscopic agent such as lithum chloride or the like. As shown in a drawing attached hereto and labelled prior art, a moisture exchange of this type is housed in a rotary of the drum shape which rotates at a low speed. The process air is fed from one side of the rotary to the other side thereof by using a portion of the moisture exchanger to be dehumidified to become the dried air.
By using the other portion of the moisture exchanger, the regeneration air which has been heated by a heater is fed from the other side of the rotary to the first side thereof to become the regenerated exhaust air by taking up the moisture which has been absorbed in the moisture exchanger. Although the moisture exchanger is dried and regenerated by the re-generation air, it is constantly subjected to the moisture, thereby the laminated structure tends to disintegrated to the stage of destruction thereof in the end. The afore-mentioned problem is not limited to such a moisture exchanging member, but is universally encountered in other types of exchangers such as an exchanger between moisture and heat or a heat exchanger which is impregnated with a hygroscopic agent.
In order to solve such detrimental problems, there has heretofore been provided a process wherein several ~4~48 chemically active inorganic substances, for instance, water glass, are impregnated in a moisture exchanger member in a form of an aqueous dispersion to form insoluble deposited substances which are used as lamination frames reinforcing the structure thereof. However, in such a case, the above mentioned process requires various additional steps such as the step of impregnating the water glass with aqueous dis-persion, the step of impregnating water glass with other agueous dispersion in order to make the water glass insoluble salts and the step of drying, thus complicating the whole manufacturing process.
The present invention aims at providing an exchanger for heat and/or moisture free of the above mentioned conven-tional technical problems and such an object of the present invention is achieved by using as the basic paper a paper made by mixing synthetic pulp having water repellent and thermo-plastic properties with the basic fiber material and by coating the said mixed paper with abrasion resistant material in the end face of the exchanger member. This invention, in short, comprises a laminated structure of a base paper made with synthetic pulp having water repellent and thermo-plastic properties and having a low melting point which is thermo-formed into a corrugated form and further laminated, and a hygroscopic agent which is impregnated in the said laminated structure and is characterized in that it is housed inside a rotor of a drum shape. This invention comprises further a laminated structure made of a base paper made with a synthetic pulp having water repellent and thermo-plastic properties and having a low melting point which is thermoformed into a corrugation and further lamina~e~, a hygroscopic agent im-pregnated into said paper and an abrasion resistant material coated over said basic paper in the end face of the laminated 1~44~48 structure and is characterized in that it is housed inside a rotor of a drum shape.
The invention is illustrated by way of example in the accompanying drawings whereln:
Figure 1 is a diagrammatic view illustrating a rotor type dehumidifier of the prior art.
Figures 2 and 3 show an embodiment according to the present invention wherein Figure 2 is a frontal view of the exchanger in the state it is housed inside of the rotor and , Figure 3 is a cross section view along the line III-III in Figure 2.
The basic paper to be used in the present invention is structured by mixing synthetic pulp of a low-melting point such as polyethylene, nylon, acryl, polyester, polypropylene or the like which has a little hygroscopic property but has a water repellent property as well as thermo-plastic property on a base material of such fibers as as-bestos fiber, cellulose fiber, glass fiber, carbon fiber, ceramic fiber or the like. The above mixed paper is first corrugated and then laminated to form a laminated structure 5 as shown in Figure 2. In this case the mixed base paper 4 is thermoformed in a form of corrugation, therefore, the synthetic pulp which has been deformed by the thermoform between the base fiber material supports the corrugated form of the mixed base paper and further the excellent water repellent property and structure stability of the synthetic pulp enforces inter-fiber strength and stabilizes the lamination structure even under a moist condition. The laminated structure 5 is impregnated with such a hygroscopic agent as lithium chloride, lithium bromide, silica gel, activated alumina, molecular sieves or the like and the 1~44~48 impregnation therefor may be conducted at any stage during the manufacture of the base paper 4, either at a step before lamlnating the base paper 4 or at a step after laminating the structure 5.
The mixing rate of synthetic pulp and inter-fiber strength after thermoforming and under the moist conditions are substantially proportionate to each other. The relative strength compared to a water-proof paper are listed in thP
table below. In the table, each sample paper weighs 80 g/m2 and ~BKP in the composition column indicates coniferous tree breached draft pulp, NUKP coniferous tree unbreached kraft pulp, LBKP hardwood breached pulp and synthetic pulp polyethylene respectively.

Therefore, the mixing rate of the synthetic pulp is limited at its maximum so as to secure such a free space.
When considering both the inter-fiber strength and the inter-fiber frçe space in the mixed base paper, optimul ratio therebetween is that the synthetic pulp is 20 to 40% ana more preferably about 30% of the base paper in terms of weight for an exchanging member for the moisture. In the case of an exchanger member for heat, the ratio may be slightly bigger than the above.
Since the chemical substance such as ureau or phosperic compound improves flame resistance or shrink re-sistance, dimensional stability is enhanced by impregnating such agents, thus further improving st'ability of structure.
In the embodiment of the present invention, such an agent is impregnated togehter with the hygroscopic agent.
The exchanging member structure and process in the aforementioned manner is housed in a rotor 2 either in the form of a cylinder or a radially sectioned form.
As shown by the two-dot chain line in Figure 3, since a seal 6 is provided in the main body of a casing (not shown) which supports rotatively the rotor 2 so as to separate the process air A from the regeneration air C, the end face of the exchanging member 6 constantly contacts in a slidable manner with the seal 6. In order to prevent damages which might be caused by above slidable contact therebetween, the area 7 on the end face which is encircled by a broken line in Figure 3 is coated with abrasion resistent substance such as a rigid resin. By coating in such a manner, the contacting ~44~48 point with the seal 6 is hardened free of damages. It further enforces the laminated structure to improve moldability under moist condition. ~he coating with such abrasion resistant substance may be given on the mixed base paper 4 after thermo-formed or may be given thereon when laminated. But when coating on laminated condition, it is necessary to provide some measure not to close the free space between laminated layers. Due to the coating, the end face 7 of the exchanging member 1 may become unable to absorb moisture but such coated area is so small that reduction in moisture absorptive capacity is negligible. In Figures 2 and 3, the reference number 8 denotes a rotating axis of the rotor 2, 9 an enforcing rib, 10 a rim and 11 a pressing board.
As explained in the foregoing reference made to the embodiment, the exchanging member according to the present invention is structured by thermoforming a mixed base paper which is made by mixing synthetic pulp of a low melting point having thermo-plasticity but not much hygroscopic property on base fiber material, thereby the laminated structure can be retained even under moist condition because of the rigidity and water repellent property of synthetic pulp. Since the base paper itself has a capacity to retain the laminated structure, this method is advantageous in that it can eliminate additional steps such as impregnating water glass heretofore required and that it can simplify the manufacture. By coating the end face of the exchanging member alone, it can achieve a higher resistance against the seal as well as enhance stability of the lamination structure with out deteriorating the hygro-scopic water thereof.
In the prior art, there has been provided the moisture exchange for a rotary dehumidifier as this type of exchanger. In the moisture-exchanger of the above mentioned type, the basic paper usually made with asbestos fiber is corrugated, then laminated to form a so-called asbestos fiber lamination and impregnated with a hygroscopic agent such as lithum chloride or the like.
