Description

Technical Field

[0001] This invention relates to adsorption element modules, adsorption rotors, adsorption treatment devices, and treatment systems. Background Technology

[0002] Previously, a high-volume concentration device for a gas containing a low concentration of the substance to be treated (the treated gas) was known. In conventional concentration devices, the gas to be treated is passed through an adsorption element with a honeycomb structure, causing the substance to be treated to be adsorbed onto the adsorption element and removed. A small amount of heated air is then used to desorb the adsorbed substance from the adsorption element. By using a secondary treatment device such as a combustion device to treat a small volume of desorbed gas containing a high concentration of the substance to be treated (concentrated gas), the overall cost of waste gas treatment can be reduced.

[0003] For example, Japanese Patent Application Publication No. 63-84616 discloses a hollow cylindrical rotor-type (cylinder-type) adsorption treatment device that utilizes an adsorption rotor in which specific adsorption elements are arranged on the side of a hollow cylindrical cylinder.

[0004] Japanese Patent Application Publication No. 2019-209269 discloses an adsorption processing device that achieves further miniaturization by optimizing the number of honeycomb cells serving as gas channels and the content of adsorbent contained in the adsorption element in the honeycomb structure.

[0005] Japanese Patent Application Publication No. 6-126122 discloses a cylinder-type adsorption treatment device in which a non-woven fabric pad of activated carbon fiber is used as the adsorption element.

[0006] Japanese Patent Application Publication No. 54-145372 discloses a continuous harmful gas adsorption / desorption device that uses activated carbon fiber in an adsorption cylinder.

[0007] Japanese Patent Application Publication No. 6-343814 discloses a device structure for a rotary adsorption-desorption gas treatment apparatus, wherein, in its installed state, the pad-shaped adsorbent has a portion that is vertical or inclined relative to the end face of the roller.

[0008] Japanese Patent Application Publication No. 2001-120939 discloses a rotary adsorption-desorption gas treatment device, which is provided with a windproof wall to prevent one air duct chamber in the rotor from being simultaneously connected to the air inlet of the gas being treated system and the air inlet of the desorbed gas system. Summary of the Invention

[0009] The adsorption treatment devices disclosed in the above-mentioned literature are required to have higher removal performance for the substances being treated.

[0010] In a concentration unit, if the concentrated gas has a smaller flow rate and a higher concentration, the size of the combustion device in the secondary treatment unit can be smaller, and the operating energy consumption of the combustion device can be further reduced. Therefore, further high concentration is required.

[0011] When improving and exploring high-concentration adsorption elements with honeycomb structures used in conventional adsorption rotors, it is necessary to increase the adsorption capacity per unit volume of the adsorption element. Methods include, for example, increasing the ratio of adsorbent contained in the adsorption element or reducing the honeycomb size. However, in Patent Document 2, the adsorbent contained in the adsorption element reaches a high ratio of 65–85 wt.% by weight. Even with further increases in the ratio, the high-concentration effect is small, and there are concerns about a decrease in the mechanical strength of the adsorption element. Furthermore, when the honeycomb structure is reduced in size, the pressure loss of the adsorption element increases, and a large amount of energy is required to allow the gas to be treated and the heated air to be introduced into the adsorption rotor.

[0012] However, since activated carbon fiber nonwoven fabric is known to have a larger adsorption capacity and faster adsorption-desorption rate than other adsorption elements, it is expected that the adsorption treatment device using activated carbon fiber nonwoven fabric as an adsorption element, as disclosed in Patent Document 3, can achieve higher concentration than the case of using a honeycomb structure as an adsorption element. However, since the pressure loss of ordinary activated carbon fiber nonwoven fabric is very high, it is necessary to reduce the thickness of the activated carbon fiber nonwoven fabric when it is suitable for concentrating large volumes of treated gas, which may result in a decrease in the adsorption efficiency of the treated substance.

[0013] Furthermore, because the tensile strength and elongation at break of activated carbon fiber monofilaments are significantly lower than those of ordinary fibers, repeated air circulation or repeated reverse alternating air circulation in activated carbon fiber nonwoven fabric can cause fiber damage. The thickness of the activated carbon fiber nonwoven fabric will decrease over time, making it unable to maintain its original shape. As a result, there are concerns about short circuits in the treated gas within the adsorption rotor and a premature decrease in the adsorption efficiency of the treated substance.

[0014] Furthermore, in the adsorption treatment apparatus disclosed in the aforementioned patent documents, a separating component is provided between multiple adsorption elements. This separating component does not have an air passage and serves to fix the adsorption elements on the hollow cylindrical tube and prevent leakage of the gas being treated. In the adsorption treatment apparatus, the volume occupied by the separating component is a dead zone that does not directly participate in the treatment of the gas being treated; therefore, the required space is correspondingly increased, and the apparatus becomes larger.

[0015] The purpose of this invention is to provide an adsorption element module, adsorption rotor, adsorption treatment device, and treatment system that can achieve high removal performance, high concentration, long-term stabilization of the removal performance of the treated substance, and miniaturization.

[0016] According to one embodiment of the adsorption element module of the present invention, an adsorption element module is provided, wherein an adsorption element for gas passage is filled within a housing having an inlet opening and an outlet opening; the housing is configured such that all gas introduced through the inlet opening is discharged from the outlet opening after passing through the adsorption element; the adsorption element comprises activated carbon fiber nonwoven fabric; the total basis weight of the activated carbon fiber nonwoven fabric is 1200–6000 g / m³. 2 The toluene adsorption rate is 25-75 wt.%, and the fiber diameter is 15-120 μm.

[0017] In the adsorption element module, the adsorption element is configured such that the gas can flow cross-flow.

[0018] In the adsorption element module, the bulk density of the activated carbon fiber nonwoven fabric is 50–200 kg / m³. 3 Compression rate is below 30%, and compression modulus is above 80%.

[0019] In the adsorption element module, the precursor of the activated carbon fiber nonwoven fabric is mainly composed of at least one fiber selected from phenolic resin fiber, cellulose fiber and polyphenylene ether fiber.

[0020] In the adsorption element module, the adsorption element is located inside the housing, and multiple adsorption elements are stacked together.

[0021] In the adsorption element module, the adsorption element is located inside the housing, and one adsorption element is folded and stacked.

[0022] In the adsorption element module, the inlet opening and the outlet opening are closed by a plurality of spacer components. The plurality of spacer components on the inlet opening side and the plurality of spacer components on the outlet opening side are arranged in a vertically staggered position. After the treated gas passes through the gaps of the plurality of spacer components on the inlet opening side, it passes through the adsorption element and is discharged from the gaps of the plurality of spacer components on the outlet opening side.

[0023] In the adsorption element module, the adsorption element is supported by a plurality of the spacer components.

[0024] In the adsorption element module, the pressure loss of the adsorption element module is less than 1000 Pa, and the thickness in the gas flow direction is less than 500 mm.

[0025] In the adsorption element module, the unit internal volume of the adsorption element module is [m 3 The toluene adsorption capacity [kg] is 12–70 kg / m³. 3 .

[0026] According to one embodiment of the adsorption rotor of the present invention, it is a hollow cylindrical adsorption rotor that rotates about a cylindrical axis; it comprises: a plurality of adsorption element modules filled with adsorption elements through which gas can pass, and a plurality of separation members that cannot pass gas; the adsorption element modules and the separation members are arranged alternately along the circumference of the cylindrical axis; the adsorption element modules are any of the adsorption element modules described above.

[0027] According to one embodiment of the adsorption processing apparatus of the present invention, it comprises: an adsorption rotor as described above, and a channel forming member for forming a channel through which gas passes in the adsorption element module of the adsorption rotor.

[0028] In the adsorption treatment device, the channel forming component forms a gas channel such that, during the rotation of the adsorption rotor, the gas to be treated containing organic solvent, or the heating gas used to desorb organic solvent from the adsorption element module located at a specified rotation phase, passes through in the radial direction of the rotation of the cylinder shaft.

[0029] According to one embodiment of the processing system of the present invention, it comprises: the above-described adsorption processing apparatus, a pretreatment apparatus for treating the fluid to be treated before it is introduced into the adsorption processing apparatus, and / or a posttreatment apparatus for treating the desorbed gas discharged from the adsorption processing apparatus.

[0073] The following description, with reference to the accompanying drawings, illustrates various embodiments of the adsorption element module, adsorption unit, adsorption rotor, adsorption processing apparatus, and processing system based on the present invention. In the embodiments described below, when referring to numbers, quantities, etc., unless specifically stated otherwise, the scope of the present invention is not necessarily limited to those numbers, quantities, etc. The same reference numerals are used for the same parts and corresponding parts, and descriptions are not always repeated. The structures in the embodiments are intended to be used in appropriate combinations from the outset.

[0074] [Embodiment 1: Adsorption Treatment Apparatus 100]

[0075] Figure 1 This is a longitudinal cross-sectional view of the adsorption treatment apparatus 100 according to this embodiment. Figure 2 It is along Figure 1 A cross-sectional view of the adsorption treatment device 100 shown in line II-II. Figure 3 yes Figure 2 An enlarged cross-sectional view of the main part of the adsorption rotor 90 shown.

[0076] like Figures 1-3 As shown, the adsorption treatment apparatus 100 includes an adsorption rotor 90. The adsorption rotor 90 is disposed within the treatment chamber 1. The adsorption rotor 90 is configured such that fluid can flow radially. The adsorption rotor 90 is configured to rotate around the cylindrical shaft C by receiving the rotational driving force of the electric motor 3. The adsorption rotor 90 is rotatably supported on multiple support members 6, such as a support column, with the cylindrical shaft C pointing vertically, but it can also be configured such that the cylindrical shaft C points horizontally. Figure 2 , Figure 3The curved arrow shown indicates the direction of rotation of the adsorption rotor 90.

[0077] The adsorption rotor 90 consists of a pair of hollow disks 10, multiple partition components 20, and multiple adsorption element modules 30.

[0078] A pair of hollow disks 10 includes a first hollow disk 11 and a second hollow disk 12. The first hollow disk 11 and the second hollow disk 12 have annular plate shapes, with their respective centers positioned on a cylindrical shaft C. An opening 11a is formed in the central portion of the first hollow disk 11. The first hollow disk 11 and the second hollow disk 12 are arranged parallel to each other at a distance, thereby allowing a separating member 20 and an adsorption element module 30 to be arranged between them.

[0079] Between a pair of hollow disks 10 of the adsorption rotor 90, multiple separating components 20 and multiple adsorption element modules 30 are alternately arranged in the circumferential direction of the cylindrical shaft C, thereby forming a cylindrical shape. The adsorption rotor 90 has an overall hollow cylindrical shape and has a cylindrical hole 90a (central space). The cylindrical hole 90a communicates with the opening 11a of the first hollow disk 11.

[0080] Multiple partition components 20 divide the space between a pair of hollow disks 10 into multiple independent spatial portions S in the circumferential direction of the cylindrical axis C (see reference). Figure 3 The separator 20 is a component without air passages, through which gas cannot pass. The separator 20 is installed between a pair of hollow discs 10 in an airtight and / or liquid-tight manner.

[0081] Each partition member 20 includes a main body 21 and a sealing part 22. The main body 21 is formed of stainless steel or iron and constitutes the skeleton of the partition member 20. The main body 21 has a triangular cylindrical shape. The main body 21 has a top edge located on the inner circumference of the adsorption rotor 90 and a bottom part located on the outer circumference of the adsorption rotor 90. The partition members 20 are arranged such that, when viewed from above, the centroids of their triangles are evenly spaced along the circumference of the cylindrical shaft C.

[0082] A sealing portion 22 is provided around the main body portion 21. The sealing portion 22 may be integral with the main body portion 21, or it may be composed of a component different from the main body portion 21. When the sealing portion 22 is composed of a component different from the main body portion 21, the sealing portion 22 may be joined to the main body portion 21 by adhesive or the like, or it may be configured to be able to be installed and removed from the main body portion 21.

[0083] The sealing portion 22 of this embodiment has an inner peripheral sealing portion 23 and an outer peripheral sealing portion 24. The inner peripheral sealing portion 23 is located on the inner side of the adsorption rotor 90 relative to the main body 21 in the radial direction (the side closer to the cylinder shaft C). The outer peripheral sealing portion 24 is located on the outer side of the adsorption rotor 90 relative to the main body 21 in the radial direction (the side farther from the cylinder shaft C). The inner peripheral sealing portion 23 is configured to protrude from the top edge of the main body 21 toward the radially inner side of the adsorption rotor 90. The outer peripheral sealing portion 24 is configured to protrude from the bottom surface of the main body 21 toward the radially outer side of the adsorption rotor 90.

[0084] In this embodiment, the inner circumferential sealing portion 23 and the outer circumferential sealing portion 24 extend axially (in the extension direction of the cylinder shaft C) of the adsorption rotor 90 and have a rib-like shape extending radially in the adsorption rotor 90. The inner circumferential sealing portion 23 has a sealing surface 23a. The outer circumferential sealing portion 24 has a sealing surface 24a. The sealing surfaces 23a and 24a intersect the rotation direction of the adsorption rotor 90.

[0085] Sealing members 40 are provided on the inner peripheral sealing portion 23 and the outer peripheral sealing portion 24. The sealing members 40 are formed of, for example, an elastic rubber material, and have airtightness and / or liquidtightness. The sealing members 40 may have the function of separating the adsorption area where the adsorption treatment is performed (i.e., the gas to be treated is adsorbed into the adsorption element module 30) and the desorption area where the desorption treatment is performed (i.e., the gas to be treated is desorbed from the adsorption element module 30), and / or prevent the gas to be treated from leaking between the adsorption treatment device 100 and the treatment chamber 1.

[0086] The sealing member 40 includes an inner sealing member 41 located on the inner circumference of the adsorption rotor 90 and an outer sealing member 42 located on the outer circumference of the adsorption rotor 90. The inner sealing member 41 is disposed on the sealing surface 23a of the inner circumferential sealing portion 23. The inner sealing member 41 protrudes from the partition member 20 radially inward toward the adsorption rotor 90. The outer sealing member 42 is disposed on the sealing surface 24a of the outer circumferential sealing portion 24. The outer sealing member 42 protrudes from the partition member 20 radially outward toward the adsorption rotor 90. The inner sealing member 41 and the outer sealing member 42 extend continuously from one hollow disk (first hollow disk 11) to the other hollow disk (second hollow disk 12) between a pair of hollow disks 10.

[0087] The adsorption element module 30 is a component filled with adsorption elements through which gases, such as the gas being treated, can cross-pass. In the adsorption element module 30, gas can pass through the outer periphery of the adsorption rotor 90 towards the cylindrical hole 90a. Each adsorption element module 30 is housed in any one of a plurality of independent spatial portions S. A plurality of adsorption element modules 130 are arranged at intervals in the circumferential direction of the adsorption rotor 90. A separator 20 is disposed between two adjacent adsorption element modules 130 in the circumferential direction of the adsorption rotor 90.

[0088] Each adsorption element module 30 has a cuboid shape. Each adsorption element module 30 has: four first sides extending axially along the adsorption rotor 90, four second sides extending radially along the adsorption rotor 90, and four third sides extending perpendicularly to the first and second sides. In each adsorption element module 30, the first sides are significantly longer than the second and third sides. Each adsorption element module 30 has a cuboid shape with the first side as its longer side. The cross-sectional shape of the adsorption element module 30 perpendicular to the cylinder axis C is square or rectangular.

[0089] In the adsorption element module 30, for example, Figure 5 The adsorption element module 130 is shown. In the adsorption element module 130, one or more layers of stacked activated carbon fiber nonwoven fabric 132a are filled as the adsorption element. The gas to be treated passes through the interior of the activated carbon fiber nonwoven fabric 132a, thereby increasing the collision efficiency with the treated substance and improving the adsorption efficiency. On the other hand, when heated air is supplied to desorb the adsorbed treated substance, the contact efficiency between the activated carbon fiber nonwoven fabric 132a and the heated air also increases. Because heat energy is efficiently transferred to the activated carbon fiber nonwoven fabric 132a, the airflow rate of the heated air can be reduced. In other words, by using activated carbon fiber nonwoven fabric 132a as the adsorption element, high removal performance can be achieved, further enabling high concentration.

[0090] The total basis weight of activated carbon fiber nonwoven fabric 132a is preferably 600 g / m². 2 Above, 6000g / m 2 The following applies when the total weight is less than 600g / m³. 2 When the total weight exceeds 6000 g / m³, the collision efficiency with the treated substance decreases, and the adsorption performance of the adsorption element module 130 deteriorates. 2 At this time, pressure loss increases, and gas cannot be fully ventilated. Based on the balance between adsorption performance and pressure loss, a total basis weight of 1200 g / m³ is more preferable. 2 Above, 4000g / m 2 the following.

[0091] The toluene adsorption rate of activated carbon fiber nonwoven fabric 132a is preferably 25 wt.% or more and 75 wt.% or less. When the toluene adsorption rate is below 25 wt.%, the adsorption performance is lower than that of adsorption elements in the prior art. In addition, activated carbon fibers with high toluene adsorption rates have large total pore volume, thus reducing the fiber packing density. Therefore, when the toluene adsorption rate exceeds 75 wt.%, the tensile strength of the monofilament decreases, the tensile strength and compressive modulus of the activated carbon fiber nonwoven fabric decrease, and the shape stability of the adsorption element decreases. Based on the balance between adsorption performance and shape stability, the toluene adsorption rate is more preferably 30 wt.% or more and 70 wt.% or less.

[0092] The fiber diameter of the activated carbon fibers constituting the activated carbon fiber nonwoven fabric 132a is preferably 15 μm or more and 120 μm or less. When the fiber diameter is less than 15 μm, the pressure loss increases, and gas cannot pass through sufficiently. When the fiber diameter exceeds 120 μm, the collision efficiency with the treated substance decreases, the adsorption efficiency decreases, and the adsorption performance of the adsorption element module 130 is poor. In addition, due to the decreased contact efficiency with the heated air, heat energy is difficult to transfer to the activated carbon fiber nonwoven fabric 132a, thus increasing the airflow of the heated air. Furthermore, the softness of the activated carbon fiber nonwoven fabric 132a decreases, making it difficult to process into the adsorption element module 130. Based on the balance of pressure loss, adsorption performance, heated airflow, and processability of the adsorption element module 130, the fiber diameter is more preferably 15 μm or more and 120 μm or less.

[0093] The pressure loss of the adsorption element module 130 is preferably below 1000 Pa, more preferably below 800 Pa. When the pressure loss exceeds 1000 Pa, gas cannot pass through sufficiently. The lower limit of the pressure loss is typically above 50 Pa.

[0094] The thickness of the adsorption element module 130 is preferably 500 mm or less, more preferably 300 mm or less. Since the adsorption element module 130 has a rectangular block shape, the size of the adsorption rotor, which can be configured as a hollow cylindrical shape, is limited by the size of the adsorption element module 130. In particular, it is significantly limited by the thickness of the adsorption element module 130 in the gas flow direction. By reducing the thickness of the adsorption element module 130, the adsorption rotor can be further miniaturized.

[0095] The bulk density of activated carbon fiber nonwoven fabric 132a is preferably 50 kg / m³. 3 Above, 200kg / m 3 The following applies when the bulk density is less than 50 kg / m³. 3 At this point, the compression ratio of the nonwoven fabric increases, making it prone to wrinkling when processed into adsorption element modules 130, thus making processing difficult. When the bulk density exceeds 200 kg / m³... 3At this time, the pressure loss of the nonwoven fabric will increase, and the gas cannot pass through sufficiently. Based on the balance between the processability of the adsorption element module 130 and the pressure loss, the bulk density is more preferably 60 kg / m³. 3 Above, 150kg / m 3 the following.

[0096] The compression ratio of the activated carbon fiber nonwoven fabric 132a is preferably 30% or less, more preferably 25% or less. When the compression ratio exceeds 30%, it becomes prone to wrinkling when processed into the adsorption element module 130, thus making processing difficult. The lower limit of the compression ratio is typically 5% or more.

[0097] The compression modulus of the activated carbon fiber nonwoven fabric 132a is preferably 80% or higher, more preferably 85% or higher. If the compression modulus is less than 80%, repeated ventilation of the adsorption element module 130 or repeated reverse alternating ventilation will cause the activated carbon fiber nonwoven fabric to shift over time, creating a gas short circuit in the adsorption rotor, and the adsorption efficiency for the treated substance will decrease prematurely. The upper limit of the compression modulus is usually 99% or lower.

[0098] The adsorption element module 130 in the embodiment is manufactured by the following method. There are no particular limitations on the preparation method of the precursor nonwoven fabric of the activated carbon fiber nonwoven fabric 132a; known methods can be appropriately employed. Examples of methods for manufacturing the nonwoven fabric include spunbonding, meltblowing, hydroentangling, needle punching, thermal bonding, and chemical bonding. Needle punching is preferred.

[0099] Activated carbon fiber nonwoven fabric 132a can be manufactured by carbonizing the precursor nonwoven fabric using known methods and then activating it. Specifically, gas activation method and chemical activation method can be listed. Based on the viewpoint of improving fiber strength and purity, gas activation method is preferred.

[0100] Alternatively, activated carbon fibers can be processed into sheets using a wet papermaking method with adhesives to produce activated carbon fiber nonwoven fabric 132a.

[0101] Precursor fibers for activated carbon fibers include phenolic resin, cellulose fiber, polyphenylene ether fiber, polyacrylonitrile, asphalt, lignin, bamboo, etc. Based on the viewpoint of improving fiber strength, compressive modulus and purity, phenolic resin, cellulose fiber and polyphenylene ether fiber are preferred.

[0102] Reference Figure 4 and Figure 5 This section explains the specific configuration of the adsorption element module 130 in this embodiment. Figure 4 This is a three-dimensional view of the adsorption element module 130. Figure 5 yes Figure 4 Cross-sectional view with arrow pointing in the direction of the VV line.

[0103] The adsorption element module 130 has a rectangular housing 131. The housing 131 only needs to have sufficient strength, heat resistance, and chemical resistance under the conditions of use. Metal materials such as iron, stainless steel, and aluminum, and resin materials such as acrylic, phenolic (bakelite), and melanin can be used.

[0104] The housing 131 has an inlet opening 131a for the inflow of the fluid F1 to be treated and an outlet opening 131b for the outflow of the fluid F2 to be treated after being purified by the adsorption element module 130. The fluid F1 to be treated that flows in from the inlet opening 131a passes through the adsorption element provided in the adsorption element module 130 and is discharged from the outlet opening 131b.

[0105] The adsorption element 132 is made of flat, nonwoven activated carbon fiber. Multiple adsorption elements 132 are stacked along the flow direction of the fluid F1 being treated. The adsorption elements 132 are filled inside the cuboid housing 131 and are perpendicular to the ventilation direction.

[0106] The adsorption element module 130 in the embodiment preferably has a toluene adsorption capacity of 12-70 kg / m³ per unit internal volume. 3 When the toluene adsorption capacity per unit internal volume is less than 12 kg / m³ 3 As the number of modules increases, the size of the adsorption rotor also increases. When the toluene adsorption capacity per unit internal volume exceeds 70 kg / m³... 3 At that time, due to the increase in activated carbon fiber filling, the pressure loss increases, and the gas cannot be fully ventilated. Based on the miniaturization of the adsorption rotor and the balance of pressure loss, the toluene adsorption capacity per unit internal volume is more preferably 14 kg / m³. 3 Above, 50kg / m 3 the following.

[0107] Refer again Figures 1-3 The adsorption treatment device 100 also includes a first channel forming component 2, an inner peripheral channel forming component 4, and an outer peripheral channel forming component 5.

[0108] The structure of one end of the first channel forming component 2 is such that the interior of the first channel forming component 2 is airtight with the cylindrical hole 90a of the adsorption rotor 90, while allowing the adsorption rotor 90 to rotate around the cylindrical axis C. An annular sealing component can also be held between one end of the first channel forming component 2 and a portion of the first hollow disk 11 located around the opening 11a. The other end of the first channel forming component 2 is pulled out of the processing chamber 1.

[0109] An inner circumferential channel forming member 4 is disposed in the cylindrical hole 90a on the inner circumferential side of the adsorption rotor 90. An outer circumferential channel forming member 5 is disposed on the outer circumferential side of the adsorption rotor 90. The inner circumferential channel forming member 4 and the outer circumferential channel forming member 5 are disposed opposite to each other on the inner and outer circumferential sides of the adsorption rotor 90 in such a way as to clamp a portion of the circumferential adsorption rotor 90.

[0110] The inner peripheral channel forming member 4 is configured to extend along the cylinder bore 90a and from the opening 11a toward the outside of the adsorption rotor 90. The inner peripheral channel forming member 4 includes a portion that extends along the cylinder axis C through the opening 11a of the first hollow disk 11.

[0111] At one end of the inner peripheral channel forming member 4, an inner peripheral opening end 4a is provided, which faces the inner peripheral surface of the adsorption rotor 90. The opening surface of the inner peripheral opening end 4a is configured to face a portion of the inner peripheral surface of the adsorption rotor 90. The other end of the inner peripheral channel forming member 4 protrudes from the opening 2a provided on the first channel forming member 2 to the outside of the first channel forming member 2.

[0112] An inner circumferential curved surface 4b is provided at the edge of the inner circumferential opening end 4a located downstream of the adsorption rotor 90 in the direction of rotation. An inner circumferential curved surface 4c is provided at the edge of the inner circumferential opening end 4a located upstream of the adsorption rotor 90 in the direction of rotation. The inner circumferential curved surfaces 4b and 4c are curved along the direction of rotation of the adsorption rotor 90.

[0113] At one end of the peripheral channel forming member 5, a peripheral opening end 5a facing the peripheral side of the adsorption rotor 90 is provided. The peripheral opening end 5a is configured to face a portion of the peripheral surface of the adsorption rotor 90. The other end of the peripheral channel forming member 5 protrudes outside the processing chamber 1.

[0114] An outer peripheral curved surface 5b is provided at the edge of the outer peripheral opening end 5a located downstream of the adsorption rotor 90 in the direction of rotation. An outer peripheral curved surface 5c is provided at the edge of the outer peripheral opening end 5a located upstream of the adsorption rotor 90 in the direction of rotation. The outer peripheral curved surfaces 5b and 5c are curved along the direction of rotation.

[0115] like Figure 2 and Figure 3 As shown, the adsorption rotor 90 includes a desorption region R1 and an adsorption region R2 divided circumferentially. Multiple adsorption element modules 30 rotate around the cylindrical shaft C via the adsorption rotor 90, thereby causing the desorption region R1 and the adsorption region R2 to move alternately.

[0116] like Figure 3As shown, in the desorption region R1, multiple spatial portions S, which rotate with the adsorption rotor 90, are connected to the inner peripheral channel forming member 4 and the outer peripheral channel forming member 5. As the adsorption rotor 90 rotates, the inner sealing member 41 slides relative to the inner peripheral curved surfaces 4b and 4c, and the outer sealing member 42 slides relative to the outer peripheral curved surfaces 5b and 5c. Thus, a portion of the multiple spatial portions S is in airtight communication with the inner peripheral channel forming member 4 and the outer peripheral channel forming member 5.

[0117] Specifically, the space S located in the following positions, namely the partition member 20 located between the inner peripheral curved surface 4b and the outer peripheral curved surface 5b, and the space S between the partition member 20 located between the inner peripheral curved surface 4c and the outer peripheral curved surface 5c, is in airtight communication with the inner peripheral channel forming member 4 and the outer peripheral channel forming member 5.

[0118] The adsorption region R2 is not connected to the inner peripheral channel forming component 4 and the outer peripheral channel forming component 5, thus forming a channel different from the desorption region R1.

[0119] like Figure 1 As shown, fluid is introduced into desorption region R1 and adsorption region R2, respectively. In adsorption region R2, fluid is introduced from the radially outer side to the inner side of adsorption rotor 90. After passing through adsorption region R2, the fluid flows out through the cylindrical hole 90a of adsorption rotor 90 and from the opening 11a of the first hollow disk 11 to the outside of adsorption rotor 90. In desorption region R1, fluid that has flowed through the opening 11a of one of the pair of hollow disks 10 and passed through the interior of the inner peripheral channel forming member 4 is introduced from the radially inner side to the outer side of adsorption rotor 90.

[0120] The fluid introduced into the adsorption zone R2 is the fluid to be treated, such as waste gas. This fluid contains an organic solvent, which is the substance being treated. The fluid is purified in the adsorption zone R2.

[0121] Examples of organic solvents contained in the substances being treated in the embodiments include aldehydes such as formaldehyde, acetaldehyde, propionaldehyde, and acrolein; ketones such as methyl ethyl ketone, diacetyl, methyl isobutyl ketone, acetone, and cyclohexanone; esters such as 1,4-dioxane, 2-methyl-1,3-dioxolane, 1,3-dioxolane, tetrahydrofuran, methyl acetate, ethyl acetate, propyl acetate, butyl acetate, ethyl butyrate, and butyl butyrate; alcohols such as ethanol, n-propanol, isopropanol, and butanol; glycols such as ethylene glycol, propylene glycol, diethylene glycol, and triethylene glycol; organic acids such as acetic acid and propionic acid; phenols; and toluene. Aromatic organic compounds such as xylene, benzene, ethylbenzene, and mesitylene; cycloalkanes such as cyclohexane, methylcyclohexane, cyclopentane, and cycloheptane; ethers such as diethyl ether and allyl glycidyl ether; glycol ethers such as propylene glycol monomethyl ether, propylene glycol monoethyl ether, and propylene glycol monomethyl ether acetate; nitrile compounds such as acrylonitrile; chlorinated organic compounds such as dichloromethane, 1,2-dichloroethane, trichloroethylene, epichlorohydrin, and 2-chloromethyl-1,3-dioxolane; and organic compounds such as N-methyl-2-pyrrolidone, dimethylacetamide, and N,N-dimethylformamide.

[0122] like Figure 1 As shown, during purification, the fluid F1 to be treated, supplied to the processing chamber 1, is introduced from the outer peripheral surface of the adsorption rotor 90 into the adsorption region R2. The fluid F1 to be treated introduced into the adsorption region R2 is purified by adsorbing organic solvents through the multiple adsorption element modules 30 located in the adsorption region R2 as it passes radially from the outer peripheral surface to the inner peripheral surface of the adsorption rotor 90.

[0123] The purified fluid being treated is discharged as clean air F2 from the adsorption zone R2 to the bore 90a of the adsorption rotor 90. The clean air F2 flows out through the opening 11a of the first hollow disk 11 through the bore 90a. The clean air F2 flowing out from the opening 11a is discharged outside the processing chamber 1 through the first channel forming component 2.

[0124] In the desorption zone R1, a heated fluid F3, such as heated air, is introduced. In the desorption zone R1, the adsorption element module 30 is regenerated by desorbing the organic solvent and other substances adsorbed by the adsorption element module 30, while a concentrated fluid with a higher concentration of organic solvent is generated.

[0125] To desorb the organic solvent, a heating fluid F3 is introduced from the inner peripheral channel forming member 4 into the desorption zone R1. The heating fluid F3, introduced into the desorption zone R1, desorbs the organic solvent adsorbed therein from the multiple adsorption element modules 30 located in the desorption zone R1 by heat as it passes through the adsorption rotor 90. The heating fluid containing the organic solvent, as a concentrated fluid F4, is discharged from the desorption zone R1 to the outer peripheral channel forming member 5. The concentrated fluid F4 is discharged outside the processing chamber 1 and introduced into a post-processing device for recovery or combustion or other post-processing.

[0126] In the adsorption treatment apparatus 100, the adsorption element module 30 located in the adsorption region R2 is subjected to adsorption treatment of the substance to be treated, and the adsorption element module 30 located in the desorption region R1 after adsorption treatment is subjected to desorption treatment of the substance to be treated. By rotating the adsorption rotor 90 around the cylindrical shaft C, the adsorption element module 30 moves alternately between the desorption region R1 and the adsorption region R2, continuously performing adsorption and desorption treatment of the substance to be treated.

[0127] The treated fluid F1 introduced into the adsorption zone R2 is not limited to waste gas containing organic solvents. The heated fluid F3 introduced into the desorption zone R1 is not limited to heated air. For example, the fluid introduced into the adsorption zone R2 can also be wastewater containing organic solvents, and the fluid introduced into the desorption zone R1 can also be water vapor. In this liquid flow configuration, the inner peripheral channel forming member 4 and the outer peripheral channel forming member 5 are configured to be in liquid-tight communication with the desorption zone R1.

[0128] In the above embodiments, the example shown is that the partition member 20 has a near-triangular tube shape, but it is not limited to this. As long as it has the strength to support a pair of hollow discs 10 and can be provided with a sealing member 40, its shape can also be plate-shaped or the like, and can be appropriately modified.

[0129] In the above embodiment, an example of an adsorption treatment device 100 with a single-sided opening is described: the cylindrical hole 90a of the adsorption rotor 90 is only on one side of the axial direction (the extending direction of the cylindrical shaft C) of the adsorption rotor 90. Figure 1 The clean air F2, purified by the adsorption rotor 90, enters through the opening at the top. Figure 1 The air flows upwards towards the first channel forming component 2. The adsorption treatment apparatus 100 of this embodiment may also have a double-sided opening structure: the cylindrical hole 90a opens on both axial sides of the adsorption rotor 90, and clean air F2 flows from the cylindrical hole 90a towards... Figure 1 It flows out in both upward and downward directions.

[0130] The measurement methods for the various properties of the above-mentioned adsorption elements are as follows.

[0131] [Toluene adsorption rate q of the adsorption element]

[0132] Japanese Patent Application Publication No. 9-94422 Figure 1 In the adsorption test apparatus shown, an adsorption element dried at 120°C for 16 hours was placed in a U-shaped tube. The temperature was adjusted to 25°C, and nitrogen containing 3,800 ppm toluene was introduced for 60 minutes. The weight increase of the adsorption element was measured. The toluene adsorption rate q was calculated using the following formula: [q(weight%)=w1 / w2×100]. Here, w1 is the weight increase of the adsorption element (g), and w2 is the dried mass of the adsorption element (g).

[0133] [Fiber diameter of activated carbon fiber]

[0134] Using a scanning electron microscope (product name SU1510, manufactured by Hitachi High-Technologies), observe the microscope image and read the diameters of more than 100 fibers from the image. Calculate the average of the read fiber diameters. Note that fiber diameter refers to the diameter of the fiber.

[0135] [Basis weight of activated carbon fiber nonwoven fabric]

[0136] After drying the activated carbon fiber nonwoven fabric with hot air at 130℃ for 3 hours, the weight per unit area was measured, expressed in g / m². 2 The unit is obtained.

[0137] [Bulk density of activated carbon fiber nonwoven fabric]

[0138] Bulk density is calculated by dividing weight in grams by thickness, and the unit is kg / m³. 3 Additionally, the thickness uses an area of ​​4cm. 2 The measuring head applies a load of 1.5 gf / cm onto the activated carbon fiber nonwoven fabric. 2 Therefore, the measurement is performed.

[0139] [Compression ratio and compression modulus of activated carbon fiber nonwoven fabric]

[0140] The thickness of the activated carbon fiber nonwoven fabric was measured with an initial load of 0.02 kPa. Then, the thickness was measured again under load after 1.5 kPa for 1 minute. After removing the load and allowing it to stand for 1 minute, the thickness was measured again with an initial load of 0.02 kPa. Using the obtained thickness values, the compression ratio (in %) and compression modulus (in %) were calculated according to the formula described in JISL-19136.14.

[0141] [Pressure loss of the adsorption element module]

[0142] The adsorption element module is set on the ventilation pressure loss measuring fixture, and ventilation is carried out at a wind speed of 3.0 m / s towards the opening surface of the inlet opening 131a. The pressure loss at this time is measured in Pa.

[0143] [Example of a combined processing system]

[0144] A processing system may also be provided that includes a pretreatment device for treating the processing fluid before introducing it into the adsorption processing apparatus 100, and / or a posttreatment device for treating the desorbed gas discharged from the adsorption processing apparatus 100.

[0145] Examples of pretreatment devices include filters for removing dust, pre-adsorption units equipped with adsorbents such as granular activated carbon, activated carbon containing additives, activated alumina, and zeolite for removing deteriorating components of the adsorption element, scrubbers for removing water-soluble components, roller shutter filter units for removing coating mist, gas coolers and / or gas heaters for adjusting the temperature and humidity of the treated fluid, gas coolers and / or separators for pre-liquefying and recovering the treated fluid, and recovery devices containing activated carbon or the like for pre-liquefying and recovering the treated fluid.

[0146] Examples of post-treatment devices include combustion devices (direct combustion, catalytic combustion, regenerative combustion, etc.) that combust the desorbed gas discharged from the adsorption treatment device 100, gas coolers and / or separators for liquefying and recovering desorbed gas, recovery devices containing activated carbon or the like for liquefying and recovering desorbed gas, and buffer devices filled with adsorbent for balancing the concentration of desorbed gas.

[0147] These pre-processing and / or post-processing devices can be configured in more than one manner depending on the processing conditions.

[0148] According to the present invention, the adsorption element module, adsorption rotor, adsorption treatment device, and treatment system can achieve high removal performance, high concentration, long-term stabilization of the removal performance of the treated substance, and miniaturization.

[0149] As another embodiment, the following describes other structures of adsorption element modules having the same performance as the adsorption element module 130 described above.

[0150] [Implementation Method 2: Adsorption Element Module 140]

[0151] Reference Figures 6-10 This describes the adsorption element module 140 of this embodiment. Figure 6 This is a three-dimensional view of the adsorption element module 140. Figure 7 yes Figure 6 The cross-sectional view along line VII-VII in the middle. Figure 8This is an overall perspective view of the first support 142a used for the adsorption element module 140. Figure 9 This is an overall perspective view of the second support 142b used in the adsorption element module 140. Figure 10 This is a development diagram of the activated carbon fiber nonwoven fabric 132a used in the adsorption element module 140.

[0152] The housing 141 of the adsorption element module 140 in this embodiment has the same structure as the housing 131 in Embodiment 1, and has an inlet opening 141a for the inflow of the treated fluid F1 and an outlet opening 141b for the outflow of the treated fluid F2 after purification by the adsorption element module 140. The structure of the adsorption element 142 filled inside the housing 141 is different.

[0153] The adsorption element 142 in this embodiment, such as Figure 7 As shown in the cross-sectional structural diagram, there are more than one piece. Figure 10 The strip-shaped activated carbon fiber nonwoven fabric 132a shown is stacked in a wavy pattern and filled inside the cuboid shell 141, such that the surface formed by connecting the apexes of the wavy crests is perpendicular to the ventilation direction. In this embodiment, five sheets of activated carbon fiber nonwoven fabric 132a are stacked.

[0154] Specifically, will Figure 8 The first support 142a, which is made of wire mesh and has a wavy (pleated) shape, is shown. Figure 9 The second support 142b, which is made of a wavy (pleated) mesh, is assembled with the first support 142a and the second support 142b, and the activated carbon fiber nonwoven fabric 132a is fixed between the wavy structure formed by the assembly of the first support 142a and the second support 142b. Here, in this embodiment, the peak spacing (P) of the meshes of the first support 142a and the second support 142b is, for example, 50 to 70 mm. Furthermore, the thickness of the activated carbon fiber nonwoven fabric 132a is, for example, about 15 to 25 mm.

[0155] The materials used for the mesh in the first support 142a and the second support 142b can be any materials that have sufficient strength, heat resistance, and chemical resistance under the conditions of use. Metal materials such as iron, stainless steel, and aluminum, and resin materials such as acrylic, phenolic resin, and melanin resin can be used.

[0156] According to the structure of the adsorption element module 140 of this embodiment, activated carbon fiber nonwoven fabric 132a can be densely filled inside the housing 141 while ensuring ventilation channels. As a result, as... Figure 7 As indicated by arrow Y, the fluid F1 being processed, which flows into the adsorption element module 140 from the inlet opening 141a, must cross-flow within the activated carbon fiber nonwoven fabric 132a.

[0157] Furthermore, in conventional honeycomb structures, the fluid flows in a parallel direction relative to the surface of the adsorption element. In this embodiment, however, the fluid necessarily flows cross-flow within the activated carbon fiber nonwoven fabric 132a. This significantly improves the contact efficiency between the fluid and the adsorption element. As a result, the adsorption capacity when the treated fluid F1 passes through can be further improved. Moreover, the desorption capacity when the heated fluid F3 passes through can be further improved.

[0158] [Implementation Method 3: Adsorption Element Module 150]

[0159] Next, refer to Figures 11-13 This describes the adsorption element module 150 of this embodiment. Figure 11 This is an overall perspective view of the adsorption element module 150 of this embodiment. Figure 12 yes Figure 11 The cross-sectional view along the XII-XII line arrow direction in the image. Figure 13 This is an overall perspective view of the support 152a used for the adsorption element module 150.

[0160] The adsorption element module 150 of this embodiment differs from the adsorption element module 140 in mainly in its support structure. The structure of the housing 151 is the same as that of the above embodiments, and it has an inlet opening 151a for the inflow of the treated fluid F1 and an outlet opening 151b for the outflow of the treated fluid F2 purified by the adsorption element module 150.

[0161] The adsorption element 152 in this embodiment, such as Figure 12 As shown in the cross-sectional structural diagram, there are more than one piece. Figure 10 The strip-shaped activated carbon fiber nonwoven fabric 132a shown is stacked in a wavy pattern and filled inside the cuboid shell 151, such that the surface formed by connecting the crests is perpendicular to the ventilation direction. In this embodiment, five pieces of activated carbon fiber nonwoven fabric 132a are stacked. In this embodiment, a cotton protective nonwoven fabric 132b is used to cover the outer surface of the stacked activated carbon fiber nonwoven fabric 132a for protection.

[0162] Specifically, in this embodiment, the support 152a is as follows: Figure 13 As shown, it has a plate-like shape with a wavy wire mesh 521 sandwiched between two flat wire meshes 522. The total thickness is approximately 5 to 25 mm.

[0163] like Figure 12 As shown, the support 152a is alternately sandwiched between the wavy activated carbon fiber nonwoven fabric 132a. Here, in this embodiment, the spacing (P) of the support 152a is, for example, 50 to 70 mm. In addition, the thickness of the activated carbon fiber nonwoven fabric 132a is, for example, about 15 to 25 mm.

[0164] By adopting this structure, similar to the adsorption element module 140 of Embodiment 2 described above, it is possible to densely fill the interior of the housing 151 with activated carbon fiber nonwoven fabric 132a while ensuring ventilation channels. As a result, as... Figure 12 As indicated by arrow Y, the fluid F1 being processed, which flows into the adsorption element module 150 from the inlet opening 151a, must cross-flow within the activated carbon fiber nonwoven fabric 132a.

[0165] According to this structure, the decrease in flow rate of the fluid being treated within the housing 151 (pipeline) of a conventional honeycomb structure can be suppressed, particularly the decrease on the side of the discharge opening 151b. The flow rate of the fluid being treated F1 will not decrease in any region from the inlet opening 151a to the outlet opening 151b, making it possible for the fluid being treated F1 to pass through the activated carbon fiber nonwoven fabric 132a. As a result, the processing capacity of the fluid being treated F1 in the adsorption element module 150 can be further improved. Furthermore, the support 152a can also eliminate the flat wire mesh 522, and be constructed solely of small-interval corrugated wire mesh (pleated structure) 521.

[0166] [Embodiment 4: Adsorption Unit 30A]

[0167] The adsorption element module 30 can also be used as a single unit. Furthermore, the adsorption units described below can be considered as a whole as a single adsorption element module. (See reference...) Figure 14 and Figure 15 This explains the case where adsorption unit 30A is used as the adsorption unit in this embodiment. Figure 14 This is a three-dimensional view of the adsorption unit 30A. Figure 15 yes Figure 14 Part of the cross-sectional view with the arrow direction of the XV-XV line in the image.

[0168] The adsorption unit 30A has a rectangular housing 50 and an adsorption element module 200. The housing 50 has an inlet opening 31a for the inflow of the fluid to be treated, F1, and an outlet opening 31b for the outflow of the fluid to be treated, F2, which has been purified by the adsorption element module 200. The fluid to be treated, F1, flowing in from the inlet opening 31a passes entirely through the adsorption element, i.e., the activated carbon fiber nonwoven fabric 200c, which is disposed within the adsorption element module 200, and is discharged from the outlet opening 31b.

[0169] The housing 50 has an overall box-like shape, forming an inlet opening 31a and an outlet opening 31b. Inwardly folded flanges 34 are provided at the inlet openings 31a and outlet openings 31b of the pair of side plates 33 located on the left and right sides. Inwardly folded flanges 32 are also provided around the entire circumference of the upper and lower cover bodies 31. By providing flanges 32 and 34, the adsorption element module 200 can be prevented from flying out of the housing 50.

[0170] like Figure 14 As shown, the adsorption element module 200 has three layers stacked. A separator 35 is disposed between the stacked adsorption element modules 200. The separator 35 is configured to separate the stacked adsorption element modules 200 from the inflow side opening to the discharge side opening. By configuring the separator 35, contact and friction between the adsorption element modules 200 can be suppressed. Furthermore, the separator 35 can also be used to fix the adsorption element modules 200, thus increasing the structural stability of the stacked adsorption element modules 200.

[0171] The number of layers in the adsorption element module 200 and the number of separating components 35 can be appropriately changed according to the required strength and performance of the adsorption unit 30A. However, it also depends on the number of layers in the adsorption element module 200. Separating components 35 can be set to divide the whole into about 2 to 5 parts.

[0172] The housing 50 can be a separable structure, either by stacking the adsorption element module 200 during the assembly of the adsorption unit 30A, or by cleaning and replacing the adsorption element module 200 after the adsorption unit 30A is assembled. If welded, the adsorption unit 30A is difficult to separate once assembled. If screws or bolts are used for fixing, disassembly is easy. However, the volume of the screws and bolts must be ensured, which would result in unnecessary thickness.

[0173] Therefore, rivets 37, which are easy to disassemble and require only a small volume, are preferred as fasteners. The components secured by rivets 37 have pre-drilled through holes. Screws, bolts, etc., can also be used as fasteners if a larger volume is not a problem. Additionally, the scale of the rivets 37 shown in the figures differs from the actual dimensions to clearly indicate their installation position.

[0174] To increase the opening area of ​​the housing 50, it is preferable to use a thinner material for the housing 50, while still maintaining its structural strength. These factors should be taken into account and appropriately designed. The housing 50, the partition 35, and the rivets 37 can all be used as long as they possess sufficient strength, heat resistance, and chemical resistance under operating conditions. Metal materials such as iron, stainless steel, and aluminum, and resin materials such as acrylic, phenolic resin, and melanin can be used.

[0175] like Figure 15 As shown, the adsorption element module 200 is composed of a flat plate-shaped activated carbon fiber nonwoven fabric 200c. Multiple adsorption element modules 200 are stacked along the flow direction of the fluid F1 being treated. The activated carbon fiber nonwoven fabric 200c, serving as the adsorption element, is filled inside the cuboid housing 50 and is perpendicular to the ventilation direction.

[0176] The adsorption unit according to the present invention can process the fluid being processed with high performance. Furthermore, the adsorption unit of the present invention can be used in the aforementioned adsorption rotor, adsorption processing apparatus, and processing system. According to the adsorption rotor, adsorption processing apparatus, and processing system of the present invention, by using the adsorption unit of the present invention, the fluid being processed can be processed with even higher performance.

[0177] The structure of the activated carbon fiber nonwoven fabric 200c is the same as that of the activated carbon fiber nonwoven fabric 132a described above. Hereinafter, as another embodiment, other structures of adsorption units having the same performance as the adsorption unit 30A described above will be described.

[0178] [Embodiment 5: Adsorption Unit 30B]

[0179] Reference Figures 16-19 This describes the adsorption unit 30B of this embodiment. Figure 16 This is a three-dimensional view of the adsorption unit 30B. Figure 17 yes Figure 16 A portion of the cross-sectional view along the XVII-XVII line arrow direction. Figure 18 This is a three-dimensional view of the first support 300a used in the adsorption unit 30B. Figure 19 This is a three-dimensional view of the second support 300b used for the adsorption unit 30B.

[0180] The adsorption unit 30B of this embodiment has the same housing 50 structure as the housing 50 of embodiment 4 described above. The adsorption unit 30B has an inlet opening 31a for the treated fluid F1 to flow into and an outlet opening 31b for the treated fluid F2 to flow out after purification by the adsorption unit 30B. The structure of the adsorption element module 300 filled inside the housing 50 in the adsorption unit 30B is different.

[0181] The adsorption element module 300 in this embodiment, such as Figure 17 As shown in the cross-sectional structural diagram, one or more strips of activated carbon fiber nonwoven fabric 200c are stacked in a wavy pattern and filled inside the cuboid shell 50, such that the surface formed by connecting the apexes of the waves is perpendicular to the ventilation direction. In this embodiment, five strips of activated carbon fiber nonwoven fabric 200c are stacked.

[0182] Specifically, will Figure 18 The first support 300a, which is made of wire mesh and has a wavy (pleated) shape, is shown. Figure 19The second support 300b, which is made of a wavy (pleated) mesh, is assembled with the first support 300a and the second support 300b, and an activated carbon fiber nonwoven fabric 200c is fixed between the wavy structure formed by the assembly of the first support 300a and the second support 300b. Here, in this embodiment, the peak spacing (P) of the meshes of the first support 300a and the second support 300b is, for example, 50 to 70 mm. Furthermore, the thickness of the activated carbon fiber nonwoven fabric 200c is, for example, about 15 to 25 mm.

[0183] The materials used for the mesh in the first support 300a and the second support 300b can be any materials that possess sufficient strength, heat resistance, and chemical resistance under the conditions of use. Metal materials such as iron, stainless steel, and aluminum, as well as resin materials such as acrylic, phenolic resin, and melanin resin, can be used.

[0184] According to the structure of the adsorption unit 30B in this embodiment, activated carbon fiber nonwoven fabric 200c can be densely filled inside the housing 50 while ensuring ventilation channels. As a result, as... Figure 17 As indicated by arrow Y, the treated fluid F1 flows into the adsorption unit 30B from the inlet opening 31a and cross-flows in the activated carbon fiber nonwoven fabric 200c.

[0185] Furthermore, it can suppress the decrease in flow rate of the treated fluid within the conventional honeycomb structure housing 50 (within the pipe), particularly suppressing the decrease on the discharge opening 31b side. The flow rate of the treated fluid F1 will not decrease in any region from the inlet opening 31a to the outlet opening 31b, making it possible for the treated fluid F1 to pass through the activated carbon fiber nonwoven fabric 200c. As a result, the processing capacity of the adsorption unit 30B for the treated fluid F1 can be further improved.

[0186] [Embodiment 6: Adsorption Unit 30C]

[0187] Next, refer to Figures 20-22 This describes the adsorption unit 30C of this embodiment. Figure 20 This is an overall perspective view of the adsorption unit 30C in this embodiment. Figure 21 yes Figure 20 A portion of the cross-sectional view along the XXI-XXI line arrow direction. Figure 22 This is a three-dimensional view of the support 400a used for the adsorption unit 30C.

[0188] The adsorption unit 30C in this embodiment differs from the adsorption unit 30B described above mainly in its support structure, while the structure of the housing 50 is the same as in the aforementioned embodiments. The adsorption unit 30C has an inlet opening 31a for the inflow of the fluid F1 to be treated and an outlet opening 31b for the outflow of the fluid F2 to be treated after purification by the adsorption unit 30C.

[0189] The adsorption element module 400 in this embodiment, such as Figure 21 As shown in the cross-sectional structural diagram, one or more strips of activated carbon fiber nonwoven fabric 200c are stacked in a wavy pattern and filled inside the cuboid shell 50, such that the surface formed by connecting the apexes of the waves is perpendicular to the ventilation direction. In this embodiment, five strips of activated carbon fiber nonwoven fabric 200c are stacked. In this embodiment, a cotton protective nonwoven fabric 200d is used to cover the outer surface of the stacked activated carbon fiber nonwoven fabric 200c for protection.

[0190] Specifically, in this embodiment, the support 400a is as follows: Figure 22 As shown, it has a plate-like shape with a wavy wire mesh 401 sandwiched between two flat wire meshes 402. The total thickness is approximately 5 to 25 mm.

[0191] like Figure 21 As shown, the support 400a is alternately sandwiched between the wavy activated carbon fiber nonwoven fabrics 200c. Here, in this embodiment, the spacing (P) of the support 400a is, for example, 50 to 70 mm. Furthermore, the thickness of the activated carbon fiber nonwoven fabrics 200c is, for example, about 15 to 25 mm.

[0192] By employing this structure, similar to the adsorption unit 30B in Embodiment 5 described above, it is possible to densely fill the interior of the housing 50 with activated carbon fiber nonwoven fabric 200c while ensuring ventilation channels. The result is that, as... Figure 21 As indicated by arrow Y, the treated fluid F1 flows into the adsorption unit 30C from the inlet opening 31a and cross-flows in the activated carbon fiber nonwoven fabric 200c.

[0193] According to this structure, the decrease in flow rate of the fluid being treated within the housing 50 (pipeline) of a conventional honeycomb structure can be suppressed, particularly the decrease at the discharge opening 31b. The flow rate of the fluid being treated, F1, will not decrease in any region from the inlet opening 31a to the outlet opening 31b, making it possible for the fluid being treated, F1, to pass through the activated carbon fiber nonwoven fabric 200c. As a result, the processing capacity of the adsorption unit 30C for the fluid being treated, F1, can be further improved. Furthermore, the support 400a can also eliminate the flat mesh 402, and be constructed solely of a corrugated mesh (pleated structure) 401 with small intervals.

[0194] [Implementation Method 7: Adsorption Unit 30D]

[0195] Next, refer to Figures 23-27 This describes the adsorption unit 30D of this embodiment. Figure 23 This is an overall perspective view of the adsorption unit 30D in this embodiment. Figure 24 yes Figure 23The cross-sectional view along the XXIV-XXIV line arrow direction. Figure 25 This is a three-dimensional view of the adsorption unit 30D with the shell 51 removed. Figure 26 This is a perspective view showing the first spacer component 60. Figure 27 This is a perspective view showing the second spacer component 61.

[0196] The adsorption unit 30D has a rectangular housing 51 and an adsorption element module 500. The housing 51 has an inlet opening 31a for the treated fluid F1 to flow into and an outlet opening 31b for the treated fluid F2 purified by the adsorption element module 500 to flow out. The treated fluid F1 flowing in from the inlet opening 31a passes entirely through the adsorption element, i.e., the activated carbon fiber nonwoven fabric 200c, which is disposed in the adsorption element module 500, and is discharged from the outlet opening 31b.

[0197] In the adsorption unit 30D of this embodiment, unlike the embodiments described above, spacer members are provided on the inlet opening 31a side and the outlet opening 31b side of the housing 51. Figure 25 As shown, the first spacer member 60 on the side of the inlet opening 31a is fixed to the flange 34 by rivets 37. Six first spacer members 60 are fixed to the flange 34 on the side of the inlet opening 31a. Each first spacer member 60 is fixed at two points with rivets 37 at an angle relative to the flange 34. The fluid F1 being processed flows through the gaps between the first spacer members 60.

[0198] The adsorption element module 500 in this embodiment, such as Figure 24 As shown in the cross-sectional structural diagram, inside the cuboid shell 51, multiple flat activated carbon fiber nonwoven fabrics 200c, which serve as adsorption elements, are stacked and filled horizontally with the air circulation direction.

[0199] like Figure 24 , Figure 25 As shown, the activated carbon fiber nonwoven fabric 200c is configured to be sandwiched between two flat wire meshes 500a. The activated carbon fiber nonwoven fabric 200c is composed of... Figure 26 The first spacer component 60 shown and Figure 27 The second spacer component 61 shown is supported.

[0200] like Figure 26 As shown, the first spacer 60 is a plate bent to hold the activated carbon fiber nonwoven fabric 200c, and has two grooves. Holes 500d are provided at two locations on the diagonal spanning the two grooves.

[0201] like Figure 27 As shown, the second spacer 61 is a plate bent and has grooves to hold the activated carbon fiber nonwoven fabric 200c. Holes 500d are provided at both ends of the grooves.

[0202] like Figure 24 , Figure 25 As shown, on the inlet opening 31a side, six spaced-apart first spacer members 60 are arranged. On the outlet opening 31b side, at positions that contact the cover 31 vertically, second spacer members 61 are arranged, with five spaced-apart first spacer members 60 spaced between them. The first spacer members 60 and the second spacer members 61 are fixed to the housing 51 by rivets 37 passing through the through holes of the flange 34 and the hole 500d of the housing 51. Figure 23 , Figure 25 As shown, since the first spacer 60 is fixed at two points on the diagonal, compared to fixing at four intersecting points, the number of rivets 37 used can be reduced.

[0203] In this embodiment, the adsorption element module 500 and the activated carbon fiber nonwoven fabric 200c are supported by a first spacer 60 on the side of the inlet opening 31a, a first spacer 60 on the side of the outlet opening 31b, and a second spacer 61. Therefore, the activated carbon fiber nonwoven fabric 200c does not need to be supported on the position of a pair of side plates 33.

[0204] like Figure 24 As shown, in this embodiment, the first spacer 60 and the second spacer 61 are alternately arranged at positions offset from the flow direction of the fluid F1 being processed. In the adsorption unit 30D, a channel in which the fluid F1 being processed intersects with the activated carbon fiber nonwoven fabric 200c can be provided in a flat state where the activated carbon fiber nonwoven fabric 200c is not bent.

[0205] According to the structure of the adsorption unit 30D in this embodiment, activated carbon fiber nonwoven fabric 200c can be densely filled inside the housing 51 while ensuring ventilation channels. As a result, as... Figure 24 As indicated by arrow Y, the treated fluid F1 flowing into the adsorption unit 30D from the inlet opening 31a flows intersectingly with the activated carbon fiber nonwoven fabric 200c.

[0206] Furthermore, it can suppress the decrease in flow rate of the treated fluid within the housing 51 (pipeline) of a conventional honeycomb structure, particularly suppressing the decrease on the discharge opening 31b side. The flow rate of the treated fluid F1 will not decrease in any region from the inlet opening 31a to the outlet opening 31b, making it possible for the treated fluid F1 to pass through the activated carbon fiber nonwoven fabric 200c. As a result, the processing capacity of the adsorption unit 30D for the treated fluid F1 can be further improved.

[0207] The number of grooves in the first spacer 60 of this embodiment can also be increased to three or more. The activated carbon fiber nonwoven fabric 200c has a total of 12 segments, but the number of segments can also be increased or decreased.

[0208] [Implementation Method 8: Adsorption Unit 30E]

[0209] Reference Figures 28-31 This indicates that the adsorption unit is 30E. Figure 28 This is a three-dimensional view showing the adsorption unit 30E. Figures 29-31 This is a diagram showing the cross-sectional structure of the sealing component 38.

[0210] The adsorption unit 30E and Figure 23 The structure of the adsorption unit 30D shown is basically the same. The difference lies in that an annular sealing member 38, composed of elastic components, is provided on the flanges 32 and 34 of the inflow-side opening to surround the housing 51. By providing the sealing member 38, as... Figures 1-3 As shown, this can improve the airtightness of the channel when it is installed inside the cylindrical rotor 90 of the adsorption treatment device 100.

[0211] Figure 28 The adsorption unit 30E shown is an illustration of a configuration where the sealing member 38 is provided only on the inflow side of the heating fluid F3. However, it is also possible to use either a configuration where the sealing member 38 is provided only on the discharge side or on both the inflow and discharge sides.

[0212] The sealing component 38 is fixed to the flanges 32 and 34 using an adhesive or the like. The sealing component 38 is preferably an elastic component, and particularly preferably made of rubber. The rubber material can be selected based on factors such as heat resistance and chemical resistance, depending on the operating conditions.

[0213] Figures 29-31 The cross-sectional shape of the sealing member 38 is shown. In addition to the illustration, the sealing member 38 can take a variety of cross-sectional shapes.

[0214] The structure of the sealing member 38 in embodiment 8 can also be applied to various embodiments of other embodiments described above or below.

[0215] [Embodiment 9: Adsorption Unit 30F]

[0216] Reference Figures 32-36 This indicates that the adsorption unit is 30F. Figure 32 This is a three-dimensional view showing the adsorption unit 30F. Figures 33-36 This is a diagram showing the cross-sectional structure of the annular groove M1 and the sealing component 38.

[0217] The structure of the adsorption unit 30F is similar to Figure 28The adsorption unit 30E shown is basically the same. The difference is that the flanges 32 and 34 at the inflow-side opening are provided with a pair of walls 38w in such a way as to form an annular groove M1, on which a sealing member 38 is disposed. Preferably, the walls 38w are made of the same material as the housing 51 and are integrally formed with the housing 51. For example, they can be fixed by rivets, by welding, etc. The internal depth of the annular groove M1 is about 10 mm, and the internal width is about 20 mm.

[0218] Figures 33-36 The diagram shows the cross-sectional shape of the sealing member 38. Besides the diagram, the sealing member 38 can also take on a variety of cross-sectional shapes.

[0219] Thus, by arranging the sealing component 38 inside the annular groove M1, misalignment or damage to the sealing component 38 can be prevented. This further improves the airtightness of the channel when the adsorption treatment device 100 is installed inside the cylindrical rotor 90.

[0220] [Implementation Method 10: Adsorption Unit 30G]

[0221] Reference Figure 37 This indicates that the adsorption unit 30G has other structures. Figure 37 This is a three-dimensional view showing the overall adsorption unit 30G.

[0222] The structure of the adsorption unit 30G is similar to Figure 23 The adsorption unit 30D shown is basically the same. The difference is that the housing 52 is folded into three parts to form the housing 39, and a cover 31 is provided as a top plate. Since the adsorption unit 30G does not require a cover 31 on the bottom surface, the number of rivets 37 used to fix the cover 31 to the housing 39 can be reduced.

[0223] In the above embodiments, any one of the structures of the sealing component 38 of the adsorption unit 30E, the annular groove M1 and the sealing component 38 of the adsorption unit 30F, and the housing 39 of the adsorption unit 30G can be applied to any one of the adsorption units 30A, 30B, and 30C. Thus, the structures of each embodiment can be appropriately combined into an optimal structure.

[0224] In the above embodiments, it is also possible to... Figure 15 As shown, adsorption units 30B and 30C are filled into the interior of the cuboid shell 50, so that the adsorption surface of the carbon fiber nonwoven fabric 200c is perpendicular to the ventilation direction.

Figure 38 This is a three-dimensional view showing the overall structure of adsorption unit 30H.

[0227] The adsorption unit 30H and Figure 20 The basic structure of the adsorption unit 30C shown is the same. The difference lies in the shape of the strip-shaped activated carbon fiber nonwoven fabric 200c arranged inside the shell 53.

[0229] The central adsorption element module 600 has the following structure: the upper end 200e of the activated carbon fiber nonwoven fabric 200c is sandwiched between the separating member 35 and the support 400a, and the lower end 200f of the activated carbon fiber nonwoven fabric 200c is sandwiched between the separating member 35 and the support 400a. The lower adsorption element module 600 has the following structure: the upper end 200e of the activated carbon fiber nonwoven fabric 200c is sandwiched between the separating member 35 and the support 400a, and the lower end 200f of the activated carbon fiber nonwoven fabric 200c is sandwiched between the cover 31 and the support 400a.

[0230] The adsorption unit 30H is suitable for sandwiching activated carbon fiber nonwoven fabric 200c between the cover 31, the partition 35 and the support 400a, so as not to cause positional displacement or other issues.

[0233] The adsorption unit 30I and Figure 38The basic structure of the adsorption unit 30H shown is the same. The difference lies in the different positional relationship between the upper adsorption element module 710 and the lower adsorption element module 720 arranged inside the housing 54. The housing 54 of the adsorption unit 30I can be bent into three sections in the same way as the housing 52 of the adsorption unit 30G.

[0234] The adsorption element module 710 in the upper part of this embodiment has the following structure, as follows: Figure 41 As shown in the cross-sectional structural diagram, the upper end 200e of the activated carbon fiber nonwoven fabric 200c is sandwiched between the cover 31 and the support 400a, and the lower end 200f of the activated carbon fiber nonwoven fabric 200c is sandwiched between the separator 35 and the support 400a.

The upper adsorption element module 710 and the lower adsorption element module 720 are separated by a partition member 35. The end of the partition member 35 is bent into an L-shape and fixed to the side plate 33 by rivets 37.

[0237] [Implementation Method 13: Adsorption Unit 30J]

[0238] Reference Figure 42 This indicates that the adsorption unit 30J has other structures. Figure 42 This is a three-dimensional view showing the overall adsorption unit 30J.

[0239] The adsorption unit 30J and Figure 38 The basic structure of the adsorption unit 30H shown is the same. The difference is that the interior of the shell 55 has a longitudinally spaced partition 36. The adsorption unit 30J has activated carbon fiber nonwoven fabric 200c arranged on the left and right sides of the longitudinally spaced partition 36. The shell 55 of the adsorption unit 30J, like the shell 52 of the adsorption unit 30G, can be bent into three sections.

[0240] In the adsorption unit 30J, the areas enclosed by the transverse separating member 35 and the longitudinal separating member 36 can each function as an adsorption element module. The material of the separating member 36 is the same as that of the separating member 35, and it only needs to have sufficient strength, heat resistance, and chemical resistance under the conditions of use. Metal materials such as iron, stainless steel, and aluminum, as well as resin materials such as acrylic, phenolic resin (bakelite), and melanin can be used.
