Description

[Technical Field]

[0001] The present invention relates to an adsorption treatment device. [Background technology]

[0002] When treating factory exhaust gases containing VOCs by adsorption concentration, the exhaust gas may contain gaseous substances other than VOCs that reduce the adsorption performance. Adsorbents with reduced adsorption performance will need to be replaced.

[0003] The adsorbent body provided in the disk-type adsorption treatment device is specially molded as a single unit, which makes the manufacturing cost relatively high. Furthermore, when replacing this adsorbent body, the entire body must be replaced, which is labor-intensive.

[0004] On the other hand, the multiple adsorbents provided in the cylindrical adsorption treatment device each have a standard shape, which reduces manufacturing costs, and the adsorbents can be replaced partially, making the replacement work easy.

[0005] Adsorption performance may be reduced due to factors other than gaseous substances, such as mist and dust, which can clog the adsorbent if they are present in the fluid to be treated.

[0006] In disk-type adsorption treatment devices, the adsorbent rotates with the seal member separating the adsorption compartment from the desorption compartment in direct contact with the adsorbent, which can cause mist and dust contained in the treated fluid to be pressed against the adsorbent by the seal member, which can promote clogging of the adsorbent.

[0007] On the other hand, in a cylinder-type adsorption treatment device, the seal member separating the adsorption compartment from the desorption compartment does not come into direct contact with the adsorbent, and therefore does not promote clogging of the adsorbent due to mist or dust.

[0008] As described above, when considering adsorption performance, it can be said that cylinder-type adsorption treatment devices are more suitable than disk-type adsorption treatment devices when treating a fluid to be treated that contains substances that affect the adsorbent.

[0009] Such a cylindrical adsorption treatment device is disclosed in International Publication No. 2017 / 006785 (Patent Document 1). [Prior art documents] [Patent documents]

[0010] [Patent Document 1] International Publication No. 2017 / 006785 Summary of the Invention [Problem to be solved by the invention]

[0011] In recent years, as adsorption treatment devices have become larger, the components that make up the adsorption treatment devices have also become larger, and therefore it is required that consumable materials such as the above-mentioned sealing members be easily replaceable.

[0012] The above-mentioned Patent Document 1 discloses a configuration in which the seal member that slides on the sliding member can be replaced.

[0013] However, since the seal member is provided around the entire circumference of the rotating body that is driven to rotate, a large number of work steps are still required to attach and replace the seal member.

[0014] The present invention has been made in view of the above-mentioned problems, and has as its object to provide an adsorption treatment device having a configuration that allows easy installation of a seal member, etc. [Means for solving the problem]

[0016] The sealing body includes a plurality of sealing members arranged in parallel in the rotational direction of the cylindrical rotor, and a holding member that holds the plurality of sealing members, and the sealing body is installed on the detachment inlet path member and the detachment outlet path member so that the plurality of sealing members can slide in contact with the partition body when the cylindrical rotor rotates, separating the adsorption area from the desorption area, and the adsorption area and the desorption area are airtightly separated by the sealing member of the plurality of sealing members that slides in contact with the partition body.

[0017] In another embodiment, the partition body has a shape in which the contact surface with the seal member bulges toward the seal member.

[0018] In another embodiment, the seal body is detachably provided on the detachable inlet path member and the detachable outlet path member. [Effects of the Invention]

[0021] The adsorption treatment device of this embodiment will be described below with reference to the drawings. In the embodiments and examples described below, when numbers, quantities, etc. are mentioned, the scope of the present invention is not necessarily limited to those numbers, quantities, etc., unless otherwise specified. The same reference numerals are used for the same or corresponding parts, and redundant descriptions may not be repeated. The drawings are not drawn to scale, but rather, in some places, the scale is changed to clarify the structure in order to facilitate understanding of the structure.

[0022] Fig. 1 is a longitudinal cross-sectional view of an adsorption treatment device according to this embodiment, Fig. 2 is a cross-sectional view taken along line II-II in Fig. 1, and Fig. 3 is an enlarged cross-sectional view of a main part of the cylindrical rotor shown in Fig. 1. The adsorption treatment device 100 according to this embodiment will be described with reference to Figs. 1 to 3.

[0023] 1, an adsorption treatment device 100 according to this embodiment uses an adsorbent 30 (described later) to adsorb and remove substances to be treated contained in a large volume of a fluid to be treated F1 supplied into a treatment chamber 1, and discharges purified clean air F2. The adsorption treatment device 100 desorbs the substances to be treated from the adsorbent 30 by spraying a small amount of heated fluid F3 onto the adsorbent 30 to which the adsorbed and removed substances to be treated have been adsorbed, and discharges the desorbed substances as a concentrated fluid F4.

[0024] The adsorption treatment of the target substance is carried out in an adsorption region R2 (see FIG. 3) of the cylindrical rotor 90, which will be described later. The adsorption region R2 corresponds to the adsorption region. The desorption treatment of the target substance is carried out in a desorption region R1 (see FIG. 3) of the cylindrical rotor 90, which will be described later.

[0025] The cylindrical rotor 90 is provided with a rotation mechanism M1 for rotating the cylindrical rotor 90 about the cylindrical axis C. As the cylindrical rotor 90 rotates about the cylindrical axis C, an adsorption process is performed on the adsorbent 30 that has passed through the desorption region R1 and is positioned in the adsorption region R2, and after the adsorption process, a desorption process is performed on the adsorbent 30 that has passed through the adsorption region R2 and is positioned in the desorption region R1. In this way, the adsorption process and the desorption process are performed continuously in the adsorption treatment device 100.

[0026] As shown in Figures 1 to 3, the adsorption treatment device 100 includes a cylindrical rotor 90 as a rotating body, a first flow path forming member 2, an inner circumference side flow path forming member 4 as an inlet section side flow path forming member, and an outer circumference side flow path forming member 5 as an outlet section side flow path forming member.

[0027] The cylindrical rotor 90 is installed in the processing chamber 1. The cylindrical rotor 90 is provided so that a fluid can flow in the radial direction. The cylindrical rotor 90 is provided so as to be rotatable about a cylindrical axis C. In this embodiment, the cylindrical rotor 90 is rotatably supported by a plurality of support members 6 such as pillars, with the cylindrical axis C oriented vertically.

[0028] The cylindrical rotor 90 is composed of a pair of disks 10, a plurality of partitions 20, and a plurality of adsorber 30.

[0029] The pair of disks 10 are arranged to face each other. The pair of disks 10 includes a first disk 11 and a second disk 12. An opening 11a is provided in the center of the first disk 11. The first disk 11 and the second disk 12 are arranged to face each other so that their centers overlap when viewed from the direction of the cylindrical axis C of the cylindrical rotor 90. The first disk 11 and the second disk 12 are arranged at a distance from each other so that the partition 20 and the adsorber 30 can be placed between them.

[0030] The partitions 20 divide the space between the pair of disks 10 into a plurality of space portions S (see FIG. 3) that are independent from each other in the circumferential direction. Specifically, the partitions 20 divide the space between the pair of disks 10 in the portion where the first disk 11 and the second disk 12 overlap, as viewed from the direction of the cylinder axis C, into a plurality of space portions S that are independent from each other in the circumferential direction.

[0031] The partitions 20 are arranged such that their centers O (see FIG. 3) are aligned in the circumferential direction at a predetermined pitch. The partitions 20 are attached between the pair of disks 10 so as to be airtight and / or liquidtight in the direction of the cylinder axis C.

[0032] The plurality of adsorbents 30 are respectively housed in a plurality of mutually independent spaces S. The plurality of adsorbents 30 are lined up in the circumferential direction at a predetermined pitch. The adsorbents 30 have, for example, a block shape.

[0033] The adsorbent 30 is made of an adsorbent material containing any of activated alumina, silica gel, activated carbon, and zeolite. Preferably, activated carbon or zeolite in granular, powder, or honeycomb form is used for the adsorbent 30. Activated carbon and zeolite are excellent at adsorbing and desorbing low-concentration organic compounds. By using a honeycomb structure, the pressure loss of the fluid can be reduced, increasing the processing capacity. Furthermore, clogging due to solid matter such as dust can be suppressed.

[0034] In a cylindrical rotor 90 constructed by arranging multiple partitions 20 and multiple adsorbents 30 alternately in the circumferential direction between a pair of disks 10 to form a cylindrical shape, a central space 90a is formed so as to communicate with the opening 11a of the first disk 11.

[0035] One end side of the first flow path forming member 2 is configured to allow the cylindrical rotor 90 to rotate about the cylindrical axis C while maintaining an airtight seal between the interior of the first flow path forming member 2 and a central space 90a of the cylindrical rotor 90. Specifically, for example, a flange portion is provided on one end side of the first flow path forming member 2, and an annular seal member is sandwiched between the flange portion and a portion of the first disk 11 located on the periphery of the opening 11a. The other end side of the first flow path forming member 2 is drawn out to the outside of the processing chamber 1.

[0036] An inner periphery-side flow path forming member 4 constituting a desorption inlet path member is disposed in a central space portion 90a on the inner periphery side of the cylindrical rotor 90. An outer periphery-side flow path forming member 5 constituting a desorption outlet path member is disposed on the outer periphery side of the cylindrical rotor 90. The inner periphery-side flow path forming member 4 and the outer periphery-side flow path forming member 5 are disposed facing each other on the inner periphery side and outer periphery side of the cylindrical rotor 90 so as to sandwich a part of the cylindrical rotor 90 in the circumferential direction.

[0037] The inner peripheral flow passage forming member 4 extends in the central space portion 90a along the direction of the cylindrical axis C, and is provided so as to extend outward from the cylindrical rotor 90 through the opening portion 11a.

[0038] An inner circumferential opening end 4a that faces the inner circumferential side of the cylindrical rotor 90 is provided on one end side of the inner circumferential flow path forming member 4. The opening surface of the inner circumferential opening end 4a is provided so as to face a partial region of the inner circumferential side of the cylindrical rotor 90 in the circumferential direction. The opening surface is provided so as to face the inner circumferential side of the cylindrical rotor 90 in the direction of the cylindrical axis C, extending between the first disk 11 and the second disk 12 of the inner circumferential flow path forming member 4. The other end side of the inner circumferential flow path forming member 4 protrudes to the outside of the first flow path forming member 2 from an opening 2a provided in the first flow path forming member 2.

[0039] An outer peripheral opening end 5a is provided at one end of the outer peripheral flow path forming member 5, facing the outer peripheral side of the cylindrical rotor 90. The opening surface of the outer peripheral opening end 5a is provided so as to face a partial region of the outer peripheral side of the cylindrical rotor in the circumferential direction. The opening surface is provided so as to face the outer peripheral side of the cylindrical rotor 90 in the direction of the cylindrical axis C, extending between the first disk 11 and the second disk 12.

[0040] 2 and 3, the cylindrical rotor 90 includes a desorption region R1 and an adsorption region R2 that are circumferentially partitioned. As the cylindrical rotor 90 rotates, the multiple adsorber 30 moves alternately between the desorption region R1 and the adsorption region R2.

[0041] The cylindrical rotor 90 is provided with seal bodies 40 at the inner peripheral opening end 4a and the outer peripheral opening end 5a. The detailed configuration of these seal bodies 40 will be described later. The seal bodies 40 are arranged side by side in the rotation direction of the cylindrical rotor 90 (the direction of the arrows in Figures 2 and 3). The seal bodies 40 include an inner seal body 41 and an outer seal body 42.

[0042] A pair of inner seal bodies 41 are provided so as to sandwich the inner peripheral opening end 4a from the upstream and downstream sides of the cylindrical rotor 90. A pair of outer seal bodies 42 are also provided so as to sandwich the outer peripheral opening end 5a from the upstream and downstream sides of the cylindrical rotor 90.

[0043] The partition body 20 includes contact surfaces 21 and 22 with which a seal member 430 (see FIG. 6) provided in the seal body 40 comes into sliding contact. When viewed from the direction of the cylinder axis C, the partition body 20 has a trapezoidal shape.

[0044] Next, the configuration of the seal body 40 of this embodiment will be described with reference to Fig. 4 to Fig. 7. Fig. 4 is an enlarged perspective view of the seal body, Fig. 5 is a diagram showing the configuration of the inner seal body 41, Fig. 6 is a diagram showing the configuration of the seal member 430, and Fig. 7 is a diagram showing the configuration of the outer seal body 42.

[0045] As described above, the seal body 40 includes a pair of inner seal bodies 41 arranged on the inner circumferential opening end 4a side and a pair of outer seal bodies 42 arranged on the outer circumferential opening end 5a side.

[0046] The inner seal body 41 is provided with a plurality of bolt holes BH in advance, and is fastened to the inner opening end 4a side using bolts or the like. The outer seal body 42 is also provided with a plurality of bolt holes BH in advance, and is fastened to the inner opening end 4a side using bolts or the like.

[0047] 5 and 6, the inner seal body 41 includes a base member 411 extending in the axial direction of the cylindrical axis C and a plurality of seal members 430 fixed to the base member 411 using bolts B or the like. The base member 411 includes a base 411b extending in the axial direction of the cylindrical axis C, an end bracket 411a provided at an end of the base 411b in the axial direction of the cylindrical axis C, and a side bracket 411c provided on a side of the base 411b. The base 411b is curved to fit along the inner arc shape of the cylindrical rotor 90. The end bracket 411a and the side bracket 411c are provided with the bolt holes BH described above.

[0048] Seal members 430 are fixed at five locations on the inner seal body 41. The number of seal members 430 provided on the inner seal body 41 can be selected appropriately depending on the specifications required for the adsorption treatment device 100.

[0049] As shown in FIG. 6, this is a cross-section of the sealing member 430, which is provided so as to extend along the axial direction of the cylinder axis C. The sealing member 430 has a configuration in which sheet-like sealing material 431 made of a rubber material or the like is sandwiched between an inner sandwiching plate 432 and an outer sandwiching plate 433, each of which has a C-shaped cross section, so that the sealing material 431 stands up in two rows. The pitch of the standing sealing material 431 is preferably smaller than the width of the inner contact surface 21 of the partition 20. This is because even if a malfunction occurs in one sealing material 431, the other sealing material 431 can ensure airtightness. The sealing material 431 sandwiched between the inner sandwiching plate 432 and the outer sandwiching plate 433 is fixed to the base 411b by bolting them together.

[0050] 7, the outer seal body 42 includes a base member 421 extending in the axial direction of the cylindrical axis C and a plurality of seal members 430 fixed to the base member 421 using bolts B or the like. The base member 421 includes a base 421b extending in the axial direction of the cylindrical axis C, an end bracket 421a provided at an end of the base 421b in the axial direction of the cylindrical axis C, and a side bracket 421c provided on a side of the base 421b. The base 421b is curved so as to follow the arc-shaped exterior of the cylindrical rotor 90. The end bracket 421a and the side bracket 421c are provided with the bolt holes BH described above.

[0051] Seal members 430 are fixed to the outer seal body 42 at five locations. The seal members 430 provided on the outer seal body 42 have the same configuration as the inner seal body 41, but differ only in width. The pitch of the standing seal members 431 is preferably smaller than the width of the outer contact surface 22 of the partition body 20. This is because, even if a problem occurs with one seal member 431, the other seal member 431 can ensure airtightness. The number of seal members 430 provided on the inner seal body 41 can be selected appropriately depending on the specifications required for the adsorption treatment device 100.

[0052] The seal body 40 having the above-described configuration is installed on the inner flow path forming member 4, which is the desorption inlet path member, and the outer flow path forming member 5, which is the desorption outlet path member, so that the multiple seal members 430 can slide in contact with the partition body 20 when the cylindrical rotor 90 rotates, separating the adsorption region R2 and the desorption region R1.Therefore, the adsorption region R2 and the desorption region R1 are airtightly separated by the seal member 430, which slides in contact with the partition body 20, among the multiple seal members 430.

[0053] 1 to 3 again, the cylindrical rotor 90 is divided into a desorption region R1 that is airtightly connected to the inner circumference-side flow path forming member 4 and the outer circumference-side flow path forming member 5, and an adsorption region R2 that is not connected to the inner circumference-side flow path forming member 4 or the outer circumference-side flow path forming member 5 and that forms a flow path different from the desorption region R1.

[0054] Fluids are introduced into the desorption region R1 and the adsorption region R2. The flow direction of the fluid passing through the adsorption region R2 and the flow direction of the fluid passing through the desorption region R1 are preferably opposite to each other in the radial direction of the cylindrical rotor 90.

[0055] In the adsorption region R2, a fluid is introduced from the outer periphery of the cylindrical rotor 90 toward the inner periphery, passing through the central space 90a of the cylindrical rotor 90 located around the inner periphery flow path forming member 4 and flowing out from the opening 11a of the first disk 11.

[0056] On the other hand, the fluid is introduced into the desorption region R1 so as to pass through the inner periphery side flow path forming member 4 that passes through the opening 11a of the first disk 11 and then move from the inner periphery side of the cylindrical rotor 90 toward the outer periphery side.

[0057] The fluid introduced into the adsorption region R2 is a fluid to be treated, such as exhaust gas. The fluid to be treated contains an organic solvent as a substance to be treated. In the adsorption region R2, the fluid to be treated is purified.

[0058] During the purification, first, exhaust gas is introduced into the adsorption region R2 of the cylindrical rotor 90 from the outer periphery toward the inner periphery of the cylindrical rotor 90. As the exhaust gas introduced into the adsorption region R2 passes through the cylindrical rotor 90 in the radial direction, the organic solvent is adsorbed and removed by the multiple adsorbents 30 located in the adsorption region R2, thereby purifying the exhaust gas.

[0059] The purified exhaust gas flows as clean air from the adsorption region R2 into the central space 90a of the cylindrical rotor 90. The clean air that has flowed into the central space 90a of the cylindrical rotor 90 passes through the central space 90a of the cylindrical rotor in the portion positioned around the inner circumference-side flow path forming member 4, and flows out from the opening 11a of the first disk 11. The clean air that has flowed out from the opening 11a passes through the first flow path forming member 2 and is discharged to the outside of the processing chamber 1.

[0060] The fluid introduced into the desorption region R1 is a heated fluid such as heated air. In the desorption region R1, the organic solvent adsorbed in the adsorbent 30 is desorbed to regenerate the adsorbent 30 and produce a concentrated fluid with a high concentration of the organic solvent.

[0061] To desorb the organic solvent, heated air is introduced from the other end of the inner periphery-side flow path forming member 4. The heated air introduced from the other end of the inner periphery-side flow path forming member 4 passes through the inside of the inner periphery-side flow path forming member 4 passing through the opening 11a of the first disk 11, and is introduced into the desorption region R1 from one end of the inner periphery-side flow path forming member 4.

[0062] As the heated air introduced into the desorption region R1 passes through the cylindrical rotor 90 from the inner periphery to the outer periphery of the cylindrical rotor 90, the heat causes the organic solvent adsorbed to the plurality of adsorbents 30 located in the desorption region R1 to be desorbed. The heated air containing the organic solvent is discharged as a concentrated fluid from the desorption region R1 to the outer periphery-side flow path forming member 5. The concentrated fluid discharged to the outer periphery-side flow path forming member 5 is introduced into a post-treatment device where post-treatment such as recovery or combustion is performed.

[0063] In this case, the plurality of seal members 430 provided on the seal body 40 are installed on the inner periphery-side flow path forming member 4, which is a desorption inlet path member, and the outer periphery-side flow path forming member 5, which is a desorption outlet path member, so as to separate the adsorption region R2 from the desorption region R1 and to be able to slide and come into contact with the partition body 20 when the cylindrical rotor 90 rotates. As a result, the adsorption region R2 and the desorption region R1 are airtightly separated by the seal members 430 that slide and come into contact with the partition body 20.

[0064] Since the seal body 40 is constructed as a single unit from multiple seal members 430, the seal body 40 can be easily attached to the inner opening end 4a and the outer opening end 5a when assembling the adsorption treatment device 100.

[0065] If the sealing member 430 is damaged after the adsorption treatment device 100 has been put into operation, and it is time to replace the sealing member 430, it is possible to easily replace it with a new sealing member 40 by treating the sealing member 40 as a part.

[0066] (Other partition 20A) Another embodiment of the partition body 20A will be described with reference to Fig. 8. Fig. 8 is a diagram showing the configuration of another embodiment of the partition body 20A. In the above embodiment, the contact surfaces 21 and 22 of the partition body 20 are flat surfaces, but as shown in the partition body 20A shown in Fig. 8, the contact surfaces 21a and 22a may be shaped to bulge toward the seal member 430. This increases the contact area with the seal material 431, making it possible to further ensure airtightness by the seal member 430.

[0067] (Another adsorption treatment device 100A) The adsorption treatment device 100 in the above embodiment is a vertical adsorption treatment device arranged so that the cylindrical axis C of the cylindrical rotor 90 extends along the vertical direction. However, this configuration is not limited to this, and the above configuration may be changed to a horizontal adsorption treatment device 100A as shown in Fig. 9, in which the cylindrical axis C of the cylindrical rotor 90 extends along the horizontal direction, and the same effects as those of the vertical adsorption treatment device 100 can be obtained.

[0068] Although the embodiments of the present invention have been described above, the embodiments disclosed herein are illustrative in all respects and are not limiting. The scope of the present invention is defined by the claims, and includes all modifications within the meaning and scope of the claims. [Explanation of symbols]
