The inner peripheral side seal portion 23 and the outer peripheral side seal portion 24 of the present embodiment extend in the axial direction of the suction rotor 90 (the direction in which the tubular shaft C extends) and extend in the radial direction of the suction rotor 90, respectively. It has a ribbed shape. The inner peripheral side seal portion 23 has a seal surface 23a. The outer peripheral side sealing portion 24 has a sealing surface 24a. The sealing surfaces 23a and 24a intersect in the rotation direction of the suction rotor 90.

The seal member 40 has a function of partitioning an adsorption region where the adsorption process for adsorbing the gas to be processed is performed on the adsorption unit 30 and a desorption region where the desorption treatment for desorbing the gas to be processed is performed from the adsorption unit 30 and / or adsorption. It may have a function of preventing leakage of the gas to be processed between the processing apparatus 100 and the processing chamber 1.

The seal member 40 includes an inner seal member 41 located on the inner peripheral side of the suction rotor 90 and an outer seal member 42 located on the outer peripheral side of the suction rotor 90.

There is.

The adsorption unit 30 is a member filled with an adsorption element that can pass through so that gases such as a gas to be processed intersect. In the suction unit 30 of the embodiment, gas can pass from the outer peripheral surface of the suction rotor 90 toward the cylinder hole 90a. Each suction unit 30 is housed in one of a plurality of space portions S independent of each other. The plurality of suction units 30 are arranged side by side at intervals in the circumferential direction of the suction rotor 90. A partition 20 is arranged between two suction units 30 adjacent to each other in the circumferential direction of the suction rotor 90.

Each suction unit 30 has a rectangular parallelepiped outer shape. The suction unit 30 has four first sides extending in the axial direction of the suction rotor 90, four second sides extending in the radial direction of the suction rotor 90, and four fourth sides extending perpendicular to the first side and the second side. It has three sides. In the suction unit 30 of the embodiment, the first side is remarkably longer than the second side and the third side. The suction unit 30 has a rectangular parallelepiped shape with the first side as the long side. The cross-sectional shape of the suction unit 30 orthogonal to the cylinder axis C is a square or a rectangle.

The adsorption unit 30 in the present embodiment is filled with one or more layers of activated carbon fiber non-woven fabric 200c as an adsorption element. By passing the gas to be treated through the inside of the activated carbon fiber non-woven fabric 200c, the collision efficiency with the substance to be treated is improved and the adsorption efficiency is improved. On the other hand, when the heated air is supplied to desorb the adsorbed substance to be treated, the contact efficiency between the activated carbon fiber non-woven fabric 200c and the heated air is improved, and the thermal energy is efficiently transmitted to the activated carbon fiber non-woven fabric 200c. , The air volume of heated air can be reduced. That is, by using the activated carbon fiber non-woven fabric 200c as the adsorption element, high removal performance can be exhibited and further high concentration becomes possible.

The total weight of the activated carbon fiber nonwoven fabric 200c is, 600 g / ^{m 2} or more 6000 g / ^{m 2} or less. If the total basis weight is less than 600 g / m ² , the collision efficiency with the substance to be treated is deteriorated, and the adsorption performance of the adsorption unit 30 is inferior. If the total basis weight exceeds 6000 g / m ² , the pressure loss becomes high and the gas cannot be sufficiently ventilated. The balance of the adsorption performance and the pressure loss, the total basis weight, 1200 g / ^{m 2} or more 4000 g / ^{m 2} is more preferable.

The toluene adsorption rate of the activated carbon fiber non-woven fabric 200c is 25 wt. % Or more 75 wt. % Or less is preferable. Toluene adsorption rate is 25 wt. When it is less than%, the adsorption performance is lower than that of the conventional adsorption element. Further, since the activated carbon fiber having a high toluene adsorption rate has a large total pore volume, the bulk density of the fiber is low. Therefore, the toluene adsorption rate is 75 wt. If it exceeds%, the tensile strength of the single yarn is lowered, the tensile strength and compressive elastic modulus of the activated carbon fiber non-woven fabric are lowered, and the shape stability as an adsorption element is lowered. From the balance of adsorption performance and shape stability, the toluene adsorption rate is 30 wt. % Or more 70 wt. % Or less is more preferable.

The fiber diameter of the activated carbon fibers constituting the activated carbon fiber nonwoven fabric 200c is preferably 15 μm or more and 120 μm or less. If the fiber diameter is less than 15 μm, the pressure loss becomes high and the gas cannot be sufficiently ventilated. If the fiber diameter exceeds 120 μm, the collision efficiency with the substance to be treated is lowered, the adsorption efficiency is lowered, and the adsorption performance of the adsorption unit 30 is inferior. Further, since the contact efficiency with the heated air is lowered, the heat energy is less likely to be transmitted to the activated carbon fiber non-woven fabric 200c, so that the air volume of the heated air is increased. Further, the flexibility of the activated carbon fiber non-woven fabric 200c is reduced, which makes it difficult to process the adsorption unit 30. The fiber diameter is more preferably 15 μm or more and 120 μm from the viewpoint of the balance between pressure loss, adsorption performance, heated air volume, and processability to the adsorption unit 30.

The pressure loss of the suction unit 30 is preferably 1000 Pa or less, more preferably 800 Pa or less. If the pressure loss is 1000 Pa or more, the gas cannot be sufficiently ventilated. The lower limit of pressure loss is usually 50 Pa or more.

The thickness of the suction unit 30 is preferably 500 mm or less, more preferably 300 mm or less. Since the suction unit 30 has a rectangular parallelepiped block shape, the size of the suction rotor in which the suction unit 30 is arranged in a hollow columnar shape is restricted by the size of the block of the suction unit 30. In particular, the thickness of the adsorption unit 30 in the ventilation direction of the gas is greatly restricted. By reducing the thickness of the suction unit 30, the suction rotor can be made smaller.

The bulk density of the activated carbon fiber non-woven fabric 200c is preferably 50 kg / m ³ or more and 200 kg / m ³ or less. If the bulk density is less than 50 kg / m ³ , the compressibility of the non-woven fabric becomes high, and the adsorption unit 30 is easily wrinkled, which makes the processing difficult. If the bulk density exceeds 200 kg / m ³ , the pressure loss of the non-woven fabric becomes high, and the gas cannot be sufficiently ventilated. The bulk density is more preferably 60 kg / m ³ or more and 150 kg / m ³ or less in view of the balance between workability to the suction unit 30 and pressure loss.

The compressibility of the activated carbon fiber non-woven fabric 200c is preferably 30% or less, more preferably 25% or more. If the compression ratio exceeds 30%, wrinkles are likely to occur in the processing of the suction unit 30, which makes the processing difficult. The lower limit of the compression rate is usually 5% or more.

The compressive elastic modulus of the activated carbon fiber non-woven fabric 200c is preferably 80% or more, more preferably 85% or more. When the compressive elastic modulus is less than 80%, the activated carbon fiber non-woven fabric is displaced over time due to repeated ventilation to the adsorption unit 30 or alternating ventilation in the countercurrent direction, resulting in a gas short circuit in the adsorption rotor. A path is generated, and the adsorption efficiency for the substance to be treated decreases at an early stage. The upper limit of the compressive elastic modulus is usually 99% or less.

The adsorption unit 30 in the embodiment is manufactured by the following method. The method for producing the precursor nonwoven fabric of the activated carbon fiber nonwoven fabric 200c is not particularly limited, and a known method can be appropriately adopted. Examples of the method for producing the non-woven fabric include a spunbond method, a melt blow method, a spunlace method, a needle punch method, a thermal bond method, and a chemical bond method. Of these, the needle punch method is preferable.

The activated carbon fiber non-woven fabric 200c can be produced by carbonizing a precursor non-woven fabric by a known method and then activating the non-woven fabric. Specific examples thereof include a gas activation method and a chemical activation method, which improve fiber strength and purity. From the viewpoint, the gas activation method is preferable.

Alternatively, the activated carbon fiber non-woven fabric 200c can be produced by processing the activated carbon fiber into a sheet by a wet papermaking method using a binder.

Examples of the precursor fiber of the activated carbon fiber include phenol resin, cellulose fiber, polyphenylene ether fiber, polyacrylonitrile, pitch, lignin, bamboo, etc. From the viewpoint of improving fiber strength, compressive elasticity and purity, the phenol resin, Cellulose fibers and polyphenylene ether fibers are preferable.

[Adsorption unit 30A]
A case where the suction unit 30A is used as the suction unit 30 in the present embodiment will be described with reference to FIGS. 4 and 5. FIG. 4 is an overall perspective view of the suction unit 30A, and FIG. 5 is a part of a sectional view taken along line VV in FIG.

The suction unit 30A has a rectangular housing 50 and a suction element block 200. The housing 50 has an introduction opening 31a into which the fluid F1 to be processed flows in, and a discharge opening 31b in which the fluid F2 to be processed flows out after being cleaned by the adsorption element block 200. The entire amount of the fluid F1 to be treated that has flowed in from the introduction opening 31a passes through the activated carbon fiber non-woven fabric 200c, which is an adsorption element provided in the adsorption element block 200, and is discharged from the discharge opening 31b.

The housing 50 has a substantially box-shaped shape as a whole so as to form the introduction opening 31a and the discharge opening 31b. The introduction opening 31a and the discharge opening 31b of the pair of side plates 33 located on the left and right are provided with flanges 34 bent inward. Flange 32s that are bent inward are also provided on the entire circumference of the lid members 31 that are arranged vertically. By providing the flange 32 and the flange 34, it is possible to prevent the suction element block 200 from protruding from the housing 50.

As shown in FIG. 4, the adsorption element blocks 200 are stacked in three stages. A partition body 35 is arranged between the laminated adsorption element blocks 200. The partition body 35 is provided so as to extend from the inflow side opening to the discharge side opening, and divides the laminated suction element blocks 200. By arranging the partition body 35, it is possible to suppress contact and rubbing between the suction element blocks 200. Further, since the suction element block 200 can be held by the partition body 35, the stability of the structure of the laminated suction element blocks 200 can be increased.

The number of laminated suction element blocks 200 and the number of partitions 35 can be appropriately changed according to the strength and performance required for the suction unit 30A. However, depending on the number of laminated suction element blocks 200, the total number is 2 to 5. It is advisable to provide the partition body 35 so as to be divided.

When the suction element blocks 200 are laminated when the suction unit 30A is assembled, or when the suction element block 200 is cleaned or replaced after the suction unit 30A is assembled, the housing 50 may have a structure that can be divided. In joining using welding, it is difficult to divide the suction unit 30A once it is assembled. In the case of screws and bolts, it can be easily disassembled. However, it is necessary to secure the volume of screws and bolts, which causes unnecessary thickness.

Therefore, it is preferable to use the rivet 37 as a fastening member, which can be easily disassembled and can secure a small volume. The member fixed by the rivet 37 is provided with a through hole in advance. If there is no problem even if the volume is increased, screws, bolts or the like may be used as the fastening member. In the figure, in order to clarify the mounting position of the rivet 37, the ratio is different from the actual size.

In order to increase the opening area of the housing 50, it is preferable that the material used for the housing 50 is thin, but it is also necessary to maintain the strength of the structure. It may be set appropriately in consideration of these. The housing 50, the partition 35, and the rivet 37 may have sufficient strength, heat resistance, chemical resistance, etc. under the conditions of use. It is advisable to use a metal material such as iron, stainless steel or aluminum, or a resin material such as acrylic, bakelite or melanin.

As shown in FIG. 5, the adsorption element block 200 is made of a flat plate-shaped activated carbon fiber non-woven fabric 200c. A plurality of adsorption element blocks 200 are stacked and arranged along the flow direction of the fluid F1 to be processed. The activated carbon fiber non-woven fabric 200c, which is an adsorption element, is filled inside the rectangular parallelepiped housing 50 so as to be perpendicular to the ventilation direction.

The adsorption unit 30A in the embodiment preferably has a toluene adsorption amount of 12 to 70 kg / m ³ or more per internal volume. If the amount of toluene adsorbed per internal volume is less than 12 kg / m ³ , the number of blocks increases and the adsorption rotor becomes large. If the amount of toluene adsorbed per internal volume exceeds 70 kg / m ^{3, the} amount of activated carbon fiber filled increases, resulting in a high pressure loss and insufficient ventilation of gas. From balance between size and pressure loss of the adsorption rotor, toluene adsorption amount per inner volume is 14kg / m3 or 50 kg / ^{m 3} or less is more preferable.

Again, referring to FIGS. 1 to 3, the adsorption processing apparatus 100 further includes a first flow path forming member 2, an inner peripheral side flow path forming member 4, and an outer peripheral side flow path forming member 5.

One end of the first flow path forming member 2 keeps the inside of the first flow path forming member 2 and the cylinder hole 90a of the suction rotor 90 airtight, and allows the suction rotor 90 to rotate around the cylinder shaft C.
