Description

Adsorption treatment device

Technical Field

The present invention relates to an adsorption treatment apparatus.

Background

In the case where plant exhaust gas containing VOC is treated by adsorption concentration, the exhaust gas may contain gaseous substances other than VOC, which reduce the adsorption performance. The adsorbent having a lowered adsorption performance needs to be replaced.

The disk-type adsorption treatment apparatus is expensive in manufacturing cost because the adsorbent is specially integrally formed. Moreover, when the adsorbent is replaced, the entire adsorbent needs to be replaced, which requires labor for replacement.

On the other hand, since each of the plurality of adsorbents included in the cylinder-type adsorption treatment apparatus has a fixed form, the manufacturing cost thereof can be reduced. When the adsorbent is replaced, it can be partially replaced, and therefore, the replacement operation can be easily performed.

Factors other than the gaseous substance may cause a decrease in adsorption performance, and for example, smoke and dust may be cited as one of the factors. When the fluid to be treated contains smoke or dust, clogging of the adsorbent occurs due to the smoke or dust.

In the disk-type adsorption treatment apparatus, the adsorbent rotates in a state where the adsorbent is in direct contact with a seal member that partitions the adsorption section and the desorption section. Therefore, the mist and dust contained in the fluid to be treated are pressed against the adsorbent by the sealing member, and clogging of the adsorbent may be promoted.

On the other hand, in the cylinder-type adsorption treatment apparatus, the sealing member that partitions the adsorption section and the desorption section does not come into direct contact with the adsorbent, and therefore clogging of the adsorbent due to smoke or dust does not become more likely.

As described above, in consideration of adsorption performance, when a fluid to be treated containing a substance that affects an adsorbent is treated, it can be said that a cylinder type adsorption treatment apparatus is more suitable than a disk type adsorption treatment apparatus.

International publication No. 2017/006785 (patent document 1) discloses such a cylinder-type adsorption treatment apparatus.

In the embodiments and examples described below, when reference is made to a number, an amount, or the like, the scope of the present invention is not necessarily limited to the number, the amount, or the like unless otherwise specified. The same components and equivalent components may be denoted by the same reference numerals, and redundant description thereof may be omitted. In the drawings, there are portions which are not illustrated in actual size ratios but illustrated in ratios changed in order to make the structure easier to understand.

Fig. 1 is a vertical sectional view of an adsorption treatment apparatus according to the present embodiment, fig. 2 is a sectional view taken along line II-II in fig. 1, and fig. 3 is an enlarged sectional view of a main portion of the cylindrical rotor shown in fig. 1. An adsorption treatment apparatus 100 according to the present embodiment will be described with reference to fig. 1 to 3.

As shown in fig. 1, the adsorption treatment apparatus 100 of the present embodiment adsorbs and removes a substance to be treated contained in a large volume of fluid to be treated F1 supplied into the treatment chamber 1 by using an adsorbent 30 described later, and discharges cleaned clean air F2. The adsorption treatment apparatus 100 discharges the treatment target substance as the concentrated fluid F4 by spraying a small amount of the heated fluid F3 onto the adsorbent 30 adsorbing the treatment target substance after the adsorption removal, thereby desorbing the treatment target substance from the adsorbent 30.

The adsorption treatment of the treatment target substance is performed in an adsorption region R2 (see fig. 3) of the cylindrical rotor 90 described later. The adsorption region R2 corresponds to an adsorption region. The desorption process of the substance to be treated is performed in a desorption region R1 (see fig. 3) of the cylindrical rotor 90 described later.

The cylindrical rotor 90 is provided with a rotation mechanism M1 for rotating the cylindrical rotor 90 about the cylinder axis C. By rotating the cylindrical rotor 90 about the cylinder axis C, the adsorbent 30 located in the adsorption region R2 by the desorption region R1 is subjected to adsorption processing, and the adsorbent 30 located in the desorption region R1 by the adsorption region R2 after the adsorption processing is subjected to desorption processing. In this way, the adsorption treatment apparatus 100 continuously performs the adsorption treatment and the desorption treatment.

As shown in fig. 1 to 3, the adsorption processing apparatus 100 includes: a cylindrical rotor 90 as a rotating body, a first flow passage forming member 2, an inner peripheral side flow passage forming member 4 as an inlet side flow passage forming member, and an outer peripheral side flow passage forming member 5 as an outlet side flow passage forming member.

The cylindrical rotor 90 is provided in the processing chamber 1. The cylindrical rotor 90 is provided to be able to flow a fluid in a radial direction. The cylindrical rotor 90 is provided to be rotatable about the cylinder axis C. In the present embodiment, the cylindrical rotor 90 is supported rotatably by a plurality of support members 6 such as support columns with the cylinder axis C direction oriented in the vertical direction.

The cylindrical rotor 90 is composed of a pair of disks 10, a plurality of separators 20, and a plurality of adsorbents 30.

A pair of disks 10 are disposed 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 disposed to face each other so that their center positions overlap each other when viewed from the direction of the cylinder axis C of the cylindrical rotor 90. The first disk 11 and the second disk 12 are disposed to be spaced apart from each other by a distance capable of disposing the partition body 20 and the adsorbent 30.

The plurality of partition bodies 20 partition the space between the pair of disks 10 into a plurality of space portions S (see fig. 3) which are circumferentially independent of each other. Specifically, the plurality of division bodies 20 divide the space between the pair of disks 10 in the portion where the first disk 11 and the second disk 12 overlap each other into a plurality of space portions S independent of each other in the circumferential direction when viewed from the direction of the cylinder axis C.

The plurality of separators 20 are arranged such that their centers O (see fig. 3) are arranged at a predetermined pitch in the circumferential direction. The plurality of division bodies 20 are installed between the pair of disks 10 in an airtight and/or liquid-tight manner in the direction of the cylinder axis C.

Each of the plurality of adsorbents 30 is accommodated in a plurality of space portions S independent of each other. The plurality of suction bodies 30 are arranged at a predetermined pitch in the circumferential direction. The adsorbent 30 has, for example, a block shape.

The adsorbent 30 is composed of an adsorbent containing any one of activated alumina, silica gel, activated carbon, and zeolite. Preferably, the adsorbent 30 is activated carbon or zeolite in the form of granules, powder, honeycomb or the like. The activated carbon and zeolite are suitable for adsorbing and desorbing low-concentration organic compounds. By forming the honeycomb structure, the pressure loss of the fluid can be reduced, and the throughput can be increased. Further, clogging due to solid matter such as garbage can be suppressed.

Between the pair of disks 10, in the cylindrical rotor 90 configured by alternately arranging the plurality of division bodies 20 and the plurality of suction bodies 30 in a cylindrical shape in the circumferential direction, a central space portion 90a is formed so as to communicate with the opening portion 11a of the first disk 11.

One end side of the first flow path forming member 2 is configured to maintain the inside of the first flow path forming member 2 airtight with the central space portion 90a of the cylindrical rotor 90 and to allow the cylindrical rotor 90 to rotate about the cylindrical axis C. 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 the first disk 11 located at the peripheral edge of the opening 11 a. The other end side of the first flow path forming member 2 protrudes outside the processing chamber 1.

An inner peripheral flow path forming member 4 constituting a desorption inlet path member is disposed in a central space portion 90a, which is an inner peripheral side of the cylindrical rotor 90. An outer peripheral flow path forming member 5 constituting a desorption outlet path member is disposed on the outer peripheral side of the cylindrical rotor 90. The inner-side flow passage forming member 4 and the outer-side flow passage forming member 5 are disposed so as to face each other on the inner circumferential side and the outer circumferential side of the cylindrical rotor 90 so as to sandwich a part of the cylindrical rotor 90 in the circumferential direction.

The inner peripheral flow path forming member 4 is provided so as to extend in the cylindrical axis C direction in the central space portion 90a and extend outward of the cylindrical rotor 90 from the opening 11 a.

An inner peripheral side opening end portion 4a facing the inner peripheral side of the cylindrical rotor 90 is provided at one end side of the inner peripheral side flow passage forming member 4. The opening surface of the inner peripheral side opening end portion 4a is disposed so as to circumferentially face a region of a part of the inner peripheral side of the cylindrical rotor 90. The opening surface is provided so as to face the inner peripheral side of the cylindrical rotor 90 in the direction of the cylinder axis C between the first disk 11 and the second disk 12 of the inner peripheral side flow passage forming member 4. The other end side of the inner peripheral flow passage forming member 4 protrudes outward from the first flow passage forming member 2 through an opening 2a provided in the first flow passage forming member 2.

An outer peripheral side opening end portion 5a facing the outer peripheral side of the cylindrical rotor 90 is provided at one end side of the outer peripheral side flow passage forming member 5. The opening surface of the outer peripheral side opening end portion 5a is provided so as to circumferentially face a region of a part of the outer peripheral side of the cylindrical rotor. The opening surface is provided so as to face the outer peripheral side of the cylindrical rotor 90 in the direction of the cylinder axis C between the first disk 11 and the second disk 12.

As shown in fig. 2 and 3, the cylindrical rotor 90 includes a desorption region R1 and an adsorption region R2 defined in the circumferential direction. The plurality of adsorbents 30 alternately move in the desorption region R1 and the adsorption region R2 by the rotation of the cylindrical rotor 90.

The cylindrical rotor 90 is provided with a seal body 40 at the inner peripheral side open end 4a and the outer peripheral side open end 5 a. The detailed structure of the sealing body 40 will be described later. The seal body 40 is arranged in a rotational direction (an arrow direction in fig. 2 and 3) of the cylindrical rotor 90. The seal 40 includes an inner seal 41 and an outer seal 42.

The inner seal body 41 is provided in a pair so as to sandwich the inner periphery-side open end 4a from the upstream side and the downstream side of the cylindrical rotor 90. The outer seal body 42 is also provided in a pair so as to sandwich the outer peripheral side opening end portion 5a from the upstream side and the downstream side of the cylindrical rotor 90.

The separator 20 includes contact surfaces 21 and 22 that are in sliding contact with a seal member 430 (see fig. 6) provided in the seal body 40. Partition body 20 has a trapezoidal shape when viewed from the direction of cylinder axis C.

Next, the structure of the sealing body 40 of the present embodiment will be described with reference to fig. 4 to 7. Fig. 4 is an enlarged perspective view of the sealing body, fig. 5 is a view showing the structure of the inner sealing body 41, fig. 6 is a view showing the structure of the sealing member 430, and fig. 7 is a view showing the structure of the outer sealing body 42.

As described above, the seal body 40 includes the pair of inner seals 41 disposed on the inner peripheral open end 4a side and the pair of outer seals 42 disposed on the outer peripheral open end 5a side.

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

As shown in fig. 5 and 6, the inner seal body 41 includes a base member 411 extending in the axial direction of the cylindrical shaft C, and a plurality of seal members 430 fixed to the base member 411 with bolts B or the like. The base member 411 includes: a base 411b extending in the axial direction of the cylindrical shaft C, an end bracket 411a provided at an end of the base 411b in the axial direction of the cylindrical shaft C, and a side bracket 411C provided at a side of the base 411 b. The base 411b is provided in a curved shape that matches the arc shape of the inside of the cylindrical rotor 90. The bolt holes BH are provided in the end bracket 411a and the side bracket 411 c.

Seal members 430 are fixed to five portions of the inner seal body 41. The number of the sealing members 430 provided in the inner sealing body 41 can be appropriately selected according to the required specification of the adsorption treatment apparatus 100.

As shown in fig. 6, is a cross section of the seal member 430, which is provided to extend in the axial direction of the cylinder axis C. The sealing member 430 has a structure in which the sealing materials 431 are erected in two rows by sandwiching a sheet-like sealing material 431 made of a rubber member or the like between an inner sandwiching plate 432 and an outer sandwiching plate 433 having a C-shaped cross section. The pitch of the rising sealing materials 431 is preferably smaller than the width of the contact surface 21 on the inner side of the separator 20. This is because, even if a failure occurs in one of the sealing members 431, airtightness can be ensured by the other sealing member 431. The sealing material 431 is fastened with bolts in a state of being sandwiched by the inner sandwiching plate 432 and the outer sandwiching plate 433, and is fixed by being fastened together with the base 411 b.

Referring to fig. 7, the outer seal body 42 includes a base member 421 extending in the axial direction of the cylindrical shaft 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 shaft C, an end holder 421a provided at an end of the base 421b in the axial direction of the cylindrical shaft C, and a side holder 421C provided at a side of the base 421 b. The base 421b is provided in a curved shape that matches the arc shape of the outer side of the cylindrical rotor 90. The bolt holes BH are provided in the end bracket 421a and the side bracket 421 c.

Seal members 430 are fixed to five portions of the outer seal body 42. The sealing member 430 provided in the outer sealing body 42 is different from the inner sealing body 41 only in width and has the same structure. The pitch of the rising sealing materials 431 is preferably smaller than the width of the contact surface 22 on the outer side of the separator 20, because even if one sealing material 431 is defective, airtightness can be ensured by the other sealing material 431. The number of the sealing members 430 provided in the inner sealing body 41 can be appropriately selected according to the required specification of the adsorption treatment apparatus 100.

In the seal body 40 having the above configuration, since the plurality of seal members 430 are provided to the inner peripheral side flow passage forming member 4 as the desorption inlet passage member and the outer peripheral side flow passage forming member 5 as the desorption outlet passage member so as to be slidable on the partition bodies 20 and to be in contact with the partition bodies 20 when the cylindrical rotor 90 rotates, and the adsorption region R2 is separated from the separation region R1, the adsorption region R2 and the desorption region R1 are air-tightly divided by the seal members 430 that slide in contact with the partition bodies 20 among the plurality of seal members 430.

Referring again to fig. 1 to 3, the cylindrical rotor 90 is divided into a desorption region R1 and an adsorption region R2, the desorption region R1 is in airtight communication with the inner periphery side flow passage forming member 4 and the outer periphery side flow passage forming member 5, and the adsorption region R2 is not in communication with the inner periphery side flow passage forming member 4 and the outer periphery side flow passage forming member 5 and constitutes a flow passage different from the desorption region R1.

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

The fluid is introduced from the outer circumferential side toward the inner circumferential side of the cylindrical rotor 90 into the adsorption region R2 so as to flow out from the opening 11a of the first disk 11 through the central space portion 90a of the cylindrical rotor 90 located in the portion around the inner circumferential side flow passage forming member 4.

On the other hand, the fluid is introduced into the desorption region R1 from the inner circumferential side toward the outer circumferential side of the cylindrical rotor 90 after passing through the inner circumferential side flow passage forming member 4 passing through the opening 11a of the first disc 11.

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 processed is cleaned.

In cleaning, first, exhaust gas is introduced into the suction region R2 of the cylindrical rotor 90 from the outer circumferential side toward the inner circumferential side of the cylindrical rotor 90. When 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 plurality of adsorbents 30 located in the adsorption region R2, and the exhaust gas is cleaned.

The cleaned exhaust gas flows as clean air from the adsorption region R2 into the central space portion 90a of the cylindrical rotor 90. The clean air flowing into the central space 90a of the cylindrical rotor 90 passes through the central space 90a of the cylindrical rotor located around the inner peripheral flow passage forming member 4, and flows out from the opening 11a of the first disk 11. The clean air flowing out of the opening 11a passes through the first flow path forming member 2 and is discharged to the outside of the processing chamber 1.

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 on the adsorbent 30 is desorbed, whereby the adsorbent 30 is regenerated, and a concentrated fluid in which the concentration of the organic solvent is high is generated.

In order to desorb the organic solvent, heated air is introduced from the other end side of the inner peripheral side flow passage forming member 4. The heated air introduced from the other end side of the inner peripheral side flow passage forming member 4 passes through the inside of the inner peripheral side flow passage forming member 4 passing through the opening 11a of the first disk 11, and is introduced from one end side of the inner peripheral side flow passage forming member 4 into the desorption region R1.

When the heated air introduced into the desorption region R1 passes through the cylindrical rotor 90 from the inner circumferential side to the outer circumferential side of the cylindrical rotor 90, the organic solvent adsorbed by the plurality of adsorbents 30 located in the desorption region R1 is desorbed therefrom by heat. The heated air containing the organic solvent is discharged as a concentrated fluid from the desorption region R1 toward the outer peripheral side flow path forming member 5. The concentrated fluid discharged to the outer circumferential side flow path forming member 5 is introduced into a post-treatment apparatus for performing post-treatment such as recovery or combustion.

At this time, the plurality of seal members 430 provided in the seal body 40 are provided in the inner peripheral side flow passage forming member 4 as the desorption inlet passage member and the outer peripheral side flow passage forming member 5 as the desorption outlet passage member so as to be slidable on the partition bodies 20 and to be in contact with the partition bodies 20 when the cylindrical rotor 90 rotates, thereby separating the adsorption region R2 from the desorption region R1. Thereby, the adsorption region R2 and the desorption region R1 are air-tightly divided by the seal member 430 sliding in contact with the separator 20 among the plurality of seal members 430.

Since the seal body 40 is integrally formed by the plurality of seal members 430, the seal body 40 can be easily attached to the inner peripheral side open end 4a and the outer peripheral side open end 5a when the adsorption treatment device 100 is assembled.

Even when the seal member 430 is damaged after the operation of the adsorption treatment apparatus 100 or when the replacement timing of the seal member 430 comes, the seal body 40 can be easily replaced with a new one by handling the seal body 40 as a component.

(other separators 20A)

Referring to fig. 8, another embodiment of separator 20A will be described. Fig. 8 is a diagram showing the structure of separator 20A according to another embodiment. In the above embodiment, the contact surface 21 and the contact surface 22 of the division body 20 are flat surfaces, but as shown in the division body 20A shown in fig. 8, the contact surface 21a and the contact surface 22a may be formed in shapes bulging toward the seal member 430 side. This enlarges the contact area with the sealing material 431, and can further improve the securing of the airtightness by the sealing member 430.

The adsorption treatment apparatus 100 of the above embodiment is a vertical adsorption treatment apparatus disposed such that the cylinder axis C of the cylindrical rotor 90 extends in the vertical direction. However, not limited to this configuration, the configuration described above is a horizontal type adsorption processing apparatus 100A shown in the adsorption processing apparatus 100A of fig. 9, which is arranged such that the cylinder axis C of the cylindrical rotor 90 extends in the horizontal direction, and the same operational effects as those of the vertical type adsorption processing apparatus 100 can be obtained.
