Description of the Related Art When a solvent is treated using a solvent-adsorbing sheet (sheet type), for example, fibrous activated carbon is formed into paper, step-processed, and formed into a honeycomb shape having a large number of gas passages. By using a block-shaped solvent adsorbent supported by a frame and allowing the gas to be treated to permeate along the gas passage of the solvent adsorbent, the solvent is brought into contact with the gas passage peripheral wall in which the fibrous activated carbon is dispersed, and the solvent is removed. There are the following advantages as compared with the case of adsorbing (honeycomb rotor type).
In other words, in the case of the honeycomb rotor type, the gas to be treated flows along the peripheral wall of the gas passage and is adsorbed by being brought into contact with the adsorbent. poor contact efficiency of the contact area with the small Kute吸 Chakuzai and solvent, Moreover, machining large number, in spite of the size of the solvent the adsorbent becomes higher cost with a small capacity. Moreover, when the solvent adsorbent is heated and desorbed, the solvent adsorbent is large and, in addition, heat is taken by the supporting frame, so that a large amount of heat is required, and the desorbable state is obtained after desorption. In some cases, cooling is required for returning, and the running cost is high. On the other hand, in the case of the sheet type which is the object of the present invention, the solvent adsorption sheet is made of fibrous activated carbon felt or the like, so that the contact area can be increased and the contact efficiency can be improved. The thickness of the solvent adsorption sheet can be reduced, and as a result, the solvent adsorption sheet can be easily heated and cooled,
The running cost required for heating for desorption is low, and cooling for adsorption after desorption can be performed without requiring special equipment. As a solvent treatment technique having such advantages, conventionally, as shown in FIG. 15, the solvent adsorption sheet 3 is unwound from the first roll R1, and
It is wound up by the second roll R2, and during the movement from the first roll R1 to the second roll R2, the processing target gas G1
To adsorb the solvent on the solvent adsorption sheet 3 and supply heated air as a desorption gas G2 to the heating chamber H accommodating the second roll R2 to desorb the solvent from the solvent adsorption sheet 3. (For example, Japanese Patent Publication No. 53-9587).

点にある。However, in the case of the above prior art, the solvent-absorbing sheet is unwound from the first roll while being wound up by the second roll and moved to absorb the solvent onto the solvent-absorbing sheet. by supplying in parallel heated air in the heating chamber in such a time of movement, but allows at the same time adsorption and desorption, the solvent suction sheet in the second roll that is taken either wound to the end, the first roll It is necessary to rewind the solvent adsorption sheet, and the processing form must be a form in which adsorption and desorption and rewinding are alternately repeated. As a result, in order to perform long-time processing, the first
To extend the time for one adsorption operation by unwinding the entire solvent adsorption sheet from the roll, or to provide multiple solvent treatment devices and rewind the other when one is adsorbing and desorbing. Or be used alternately. In the former case, the winding diameter of the solvent-absorbing sheet is increased, which not only leads to an increase in the size of the accompanying device and cost, but also causes the heating chamber to be wound around the second roll. by the time the solvent adsorption sheet is heated pressurized becomes longer, there can be lead to abnormal Atsushi Nobori of the solvent adsorption sheet, a configuration for preventing it needed separately, size of the apparatus, cost Is inevitable. This is particularly remarkable when the moving speed of the solvent-adsorbing sheet is increased to process a high-concentration processing target gas. On the other hand, in the case of the latter, the number of the solvent processing apparatuses increases, so that the size of the apparatuses and the cost increase are inevitable. An object of the present invention is to solve the above-described drawbacks, that is, even if the concentration of the gas to be treated is higher than the concentration of the main use area in the conventional example, without increasing the size and cost of the apparatus. The point is to enable continuous processing for a long time.

防止することができる。 According to the first aspect of the present invention , the solvent adsorption sheet is circulated and moved, and the adsorbing means and the desorbing means are operated to alternately supply the gas to be treated and the gas to be desorbed. The solvent-adsorbing sheet can be repeatedly circulated so that the solvent-adsorbing sheet can adsorb the solvent from the gas to be treated and desorb the adsorbed solvent to the desorption gas. By continuously performing the movement and the supply of the gas to be treated and the supply of the desorption gas in that state, the adsorption and desorption can be performed continuously without interruption, and the solvent adsorption sheet becomes excessive during desorption. No heating. In addition, the edge in the width direction of the felt of the solvent adsorption sheet
In the state where the edge is compacted in the thickness direction,

The disadvantage of leaking from the edge)
With body and felt consolidation, or through reinforcement
Even if a conductive material is used, it is effective with the above felt consolidation part
Can be prevented. And also the width of the felt
Since the reinforcing body is fixed to the edge of the direction , when the solvent adsorption sheet is circulated, the moving force is applied to the reinforcing body instead of the felt, so that highly efficient adsorption and desorption with a small pressure loss can be performed, but also weak. While the felt of activated carbon is used for adsorption and desorption, the solvent adsorption sheet can be reliably and smoothly circulated and moved without causing damage such as cutting of the felt. Of course, by reinforcing the edge of the felt in the width direction with a reinforcing body , the felt width
Or collapse due to contact with other objects
Of the above-mentioned leak prevention function due to

Indeed, it can be prevented. According to the invention of claim 3
For example , since the solvent adsorbing sheet is formed by connecting both ends of the felt in the longitudinal direction, a solvent adsorbing sheet having a suitable peripheral length can be obtained easily and easily, and furthermore, the ends of the felt are connected together. While forming a ring-shaped solvent adsorption sheet, both edges in the longitudinal direction of the felt
With a compaction in the
A second supplement that covers the front end, the end face, and the rear end of the
Because the strong body is fixed, the processing supplied to the solvent adsorption sheet
Part of the elephant gas or desorption gas is

Inconveniences such as damage to the second reinforcement
With a compacted part, and a breathable second reinforcement
Effective with the above felt consolidation part even when using materials
Can be prevented. And also the length of the felt
The second reinforcing member is fixed to both end edges in the direction, so that the pulling force acting upon circulating movement is reduced by the second force.
Of against reinforcing member, it is possible that the pulling force on the felt itself to minimize the act, that the
In, it can be prevented even collapse from longitudinal opposite edges of the felt. According to the invention according to claim 4, the compacted longitudinal direction
Provide a packing that sandwiches the opposite edge in the thickness direction.
The second reinforcement body in the longitudinal direction with the packing of
Since it is fixed to the facing edge, it is the same as the invention according to claim 2
