し、圧力損失も大きくなる等欠点があった。(B) Prior art Activated carbon has long been used to adsorb and separate bad odors in the air, organic substances, and various dissolved substances in solutions. However, the specific surface area is small, so the adsorption capacity is also small, and the adsorption speed is slow. Therefore, when used as a device, it has to be large in size and has a large pressure loss.

ダーが必要となる。Activated carbon fibers with high adsorption capacity and high adsorption speed have been developed in recent years, but since these activated carbon fibers themselves do not have self-adhesion ability, a binder is required to form a sheet.

があるが、耐熱性は１００℃程度である。As binders, various solution-type and emulsion-type liquid binders and fibrous binders are commercially available, but the use of liquid binders is not preferable because they clog the pores of activated carbon fibers and reduce the adsorption capacity. Examples of fibrous binders include rvAm Miscellaneous's "Fibribond" and polypropylene heat-sealable fiber "Chisso Polypro ESJ".
However, the heat resistance is about 100°C.

）のが最良であるが、圧力損失が避けられない。By mixing this activated carbon fiber with other appropriate fibers (including a fibrous binder) and making paper, an activated carbon fiber sheet can now be obtained. For example, JP-A-53-1
As described in No. 15.393 and JP-A-53-134589, activated carbon fibers are mixed with recycled fibers such as pulp and rayon, and synthetic fibers such as Bo-11 ester and polyethylene. Activated carbon fiber sheets made from paper are known, but these pulps, recycled fibers, and synthetic fibers are generally flammable, have problems with heat resistance and flame retardancy, and cannot be used in environments with temperatures exceeding 150°C. However, it was not heat resistant and could not be used safely due to the risk of combustion. In order to efficiently utilize the adsorption capacity of activated carbon fibers, it is necessary to bring the activated carbon fibers into sufficient contact with the substance to be adsorbed in the fluid. For this purpose, it is best to pass (filter) the fluid in the vertical direction of the activated carbon fiber sheet, but pressure loss is unavoidable.

積層したような形が種々考案されている。In order to reduce this pressure loss as much as possible, there is a method of flowing fluid parallel to the sheet and bringing it into contact with the sheet. In this case, it is necessary to have a large contact area per unit volume to ensure sufficient adsorption, and in order to increase the contact area per unit volume, various shapes such as honeycomb shapes or stacked cardboards have been devised. ing.

耐熱性及び難燃性については、あまり問題にならなかっ
た。Activated carbon's general gas adsorption properties are that it is more easily adsorbed at low temperatures, and its efficiency decreases when used at high temperatures.In fact, at high temperatures the gas is released, so activated carbon fiber sheets that have been used until now are is rarely used at high temperatures;
Heat resistance and flame retardancy did not pose much of a problem.

An adsorption sheet (1) obtained by making paper from a slurry containing an aromatic polymer and/or inorganic short fibers is molded into a corrugated shape, and the crests of the corrugations on one or both sides of the corrugated adsorption sheet (2) are applied. The planar adsorption sheets (1) are laminated using a heat-resistant adhesive (3), rolled up in a spiral, and heat-treated to harden the heat-resistant adhesive to form a heat-resistant flame-retardant adsorbent. This relates to a method for manufacturing an adsorbent C of desired size and shape by repeating the above bonding method.

５７３２に示される如くである。Pulp-like materials made of other heat-resistant polymers, short fibers of these polymers, and short inorganic fibers to be mixed in the adsorption sheet I include the following. That is, heat-resistant aromatic polymers are aromatic bo-11amide and aromatic polyamideimide, and pulp-like materials are fibrous or polyamide polymers with a large number of protrusions that can be made into paper-like structures using a paper machine. It refers to particles that have a ribbon-like structure and have the ability to self-adhere, and can be obtained by introducing a solution of an aromatic polymer into a precipitant to precipitate fine particles. The typical manufacturing method for these is

As the inorganic short fibers, fibers of glass, ceramic, alumina, etc. are preferable.

する等の而で混合が好ましい。Short fibers do not necessarily have to be mixed into the adsorption sheet, but they can be used to adjust the pressure loss when fluid is passed (sludged) in the vertical direction of the activated carbon fiber sheet. Mixing is preferable because it improves workability by adjusting the strength of the fiber sheet, and it also adjusts the overall strength of the obtained adsorbent.
混抄させる場合は、芳香族重合体からなる繊維のみでも
よいし、これと無機質の短繊維とを混合してもよい。又
無機質の短繊維単独でもよい。In the case of mixed papermaking, the aromatic polymer fibers alone may be used, or they may be mixed with inorganic short fibers. Alternatively, inorganic short fibers may be used alone.

しいが、強度の良好なシートが得られず、父５０％以下
では、目的とする吸着能力が不十分となる。If the activated carbon fiber content is 90% or more, it is preferable in terms of adsorption capacity, but a sheet with good strength cannot be obtained, and if the content is less than 50%, the desired adsorption capacity will be insufficient.
パルプ状物は１０％以下では、得られたシートの強度が
小となり、段ボール加工及び積層加工作業性が悪くなる
ので好ましくない。If the content of the pulp-like material is less than 10%, the strength of the obtained sheet will be low and the workability of corrugated board processing and lamination processing will be poor, which is not preferable.

The structure obtained by laminating the materials with a heat-resistant adhesive was heat-resistant and flame-retardant, and could be safely used even in a high-temperature atmosphere of 150 to 200°C. In other words, the adsorbed substances that are adsorbed by fully utilizing the adsorption capacity of activated carbon fibers at low temperatures are rapidly desorbed at high temperatures, and the adsorption capacity is regenerated in a short period of time, and the adsorbed substances are separated and recovered. Or it can be removed.

剤が使用可能である。Conventional adhesives used in the production of corrugated board are starch-based adhesives, which have no heat resistance and poor water resistance.
As in the present invention, it is essential to use a heat-resistant adhesive for this adhesive, and it is essential to use a polyimide resin-based adhesive (for example, B
T-resin (Mitsubishi Gas Chemical), phenolic resin (e.g. Bryophen... Dainippon Ink Chemical), silicone resin (e.g. KE44.KE4)
Heat-resistant adhesives such as 2, . . . made of double-shrink silicone) can be used.

らない。These heat-resistant adhesives generally need to be cured by heating at high temperatures, and the adsorbents that have been molded into a corrugated shape and laminated using heat-resistant adhesives are heat-treated again until curing is completed to increase the adhesive strength. We must make full use of it.

硬化は完成されていく。Even if it is not completely cured, if it does not lose its shape, a cycle of adsorption at low temperatures and forced removal of the adsorbed material at high temperatures can be carried out continuously during operation of equipment using this adsorbent. Because the process is repeated, the high temperature heating at that time completes the curing process.

れてしまう。If a conventional starch-based adhesive is used to manufacture corrugated cardboard and a heat-resistant adhesive is used only for further lamination, the adhesive used to manufacture the corrugated cardboard will deteriorate over time during high-temperature use. The laminate deteriorates and loses its adhesive strength, causing the laminate to collapse.

かった。(billion) Effects of the invention The activated carbon fiber sheet obtained by mixing pulp, rayon, and synthetic fibers that have been used in the past cannot withstand high temperatures of more than 100°F due to the inferior heat resistance of pulp, rayon, and synthetic fibers. It is not possible to repeatedly apply heat for a long time, so even when the substances adsorbed on the activated carbon fibers are removed by heating, the removal is not sufficiently carried out, and therefore the degree of regeneration of the adsorption capacity is also low, and the adsorption and removal of the substances as a whole are insufficient. The efficiency was not good.
