Description

Technical Field

[0001] The present invention relates to a gas concentration apparatus for converting a low-concentration target gas into a high-concentration concentrated gas, and a chamber assembly used in the gas concentration apparatus. Background Technology

[0002] Conventional gas concentrators have a rotor for converting a low-concentration target gas into a high-concentration concentrated gas. The rotor is housed in a housing, which integrally includes a chamber for guiding the target gas to the rotor and a chamber for discharging the gas that has passed through the rotor. Summary of the Invention

[0003] The problem that the invention aims to solve

[0004] In conventional gas concentrators, the housing containing the rotor and the two chambers were integrated into one unit. Therefore, if either the housing or the chambers failed, the entire gas concentrator had to be replaced.

[0005] means for solving problems

[0006] The chamber assembly of the present invention includes a housing that can be detached from the direction of the rotor's rotation axis relative to a box that rotatably houses the rotor. The rotor includes a honeycomb structure carrying an adsorbent for adsorbing VOCs (Volatile Organic Compounds) contained in the gas to be processed. An opening for the gas to be processed is provided in the housing of the chamber assembly.

[0007] Within the housing, a processing zone, a regeneration zone, and a cooling zone can be arranged along the rotor's rotation direction. The processing zone is for the gas containing VOCs to pass through. The regeneration zone is for the high-temperature gas that removes the VOCs adsorbed by the rotor to pass through. The cooling zone is for the cooling gas that cools the rotor to pass through. Here, openings for the high-temperature gas and openings for the cooling gas can be provided in the housing.

[0008] The gas concentration apparatus of the present invention includes a box, a first chamber assembly, and a second chamber assembly. The box rotatably houses a rotor. The rotor has a honeycomb structure carrying an adsorbent for adsorbing VOCs (Volatile Organic Compounds) contained in the target gas. The first chamber assembly is detachably connected to one end face of the box in the direction of the rotor's rotation axis and guides the target gas to the rotor. The second chamber assembly is detachably connected to the other end face of the box in the direction of the rotor's rotation axis and discharges the target gas that has passed through the rotor.

[0009] A connection structure can be provided that allows the box and the first chamber assembly to be detachably connected using fastening members. Additionally, a connection structure can be provided that allows the box and the second chamber assembly to be detachably connected using fastening members.

[0010] As both the first and second chamber assemblies, chamber assemblies with the same structure can be used.

[0011] Within the chamber, a processing zone, a regeneration zone, and a cooling zone can be arranged along the rotor's rotation direction. The processing zone is for the gas containing VOCs to pass through. The regeneration zone is for the high-temperature gas that removes the VOCs adsorbed by the rotor to pass through. The cooling zone is for the cooling gas that cools the rotor to pass through. Openings for the gas to pass through, high-temperature gas, and cooling gas can be respectively provided in the first chamber assembly and the second chamber assembly.

[0012] Invention Effects

[0013] The chamber assembly of the present invention has a housing that can be disassembled and removable relative to the housing containing the rotor, so that the housing and the chamber assembly can be replaced separately.

[0014] The gas concentration apparatus of the present invention has a first chamber assembly and a second chamber assembly that are detachable from the cartridge, so that the cartridge, the first chamber assembly and the second chamber assembly can be replaced separately.

[0025] (The principle of gas concentration)

[0026] The gas concentration apparatus of this embodiment utilizes a rotor to convert low-concentration target gas into high-concentration concentrated gas. Specifically, the target gas is VOC (Volatile Organic Compounds) waste gas. Figure 1 The principle of gas concentration is explained. Figure 1 In this embodiment, the X, Y, and Z axes are mutually orthogonal axes. The Z-axis direction corresponds to the vertical direction. The relationship between the X, Y, and Z axes is... Figures 2 to 6 The same applies.

[0027] The rotor 10 has a cylindrical hub (not shown) that engages with a rotating shaft, multiple spokes (not shown) extending radially from the hub, and a cylindrical rim 10a connecting the front ends of each spoke. It rotates about the hub in the direction of arrow R. A honeycomb structure 11 is arranged in the space surrounded by the hub, spokes, and rim. The honeycomb structure 11 has a substrate formed of inorganic fibers or the like, and an adsorbent supported on the substrate. The adsorbent is used to adsorb VOCs; for example, zeolite can be used as the adsorbent. Multiple pores are formed in the honeycomb structure 11, each extending along the direction of the rotor 10's rotation axis (the direction in which the rotor 10's rotation axis extends), and the target gas flows along each pore.

[0028] A belt 12 is wound around the outer circumference of the rotor 10, and the belt 12 is connected to the motor 13. By transmitting the driving force of the motor 13 to the belt 12, the rotor 10 can be rotated. The motor 13 operates in response to commands from a controller (not shown).

[0029] Three spacers 14 are respectively arranged on the two end faces of the rotor 10 in the direction of its rotation axis. Figure 1 The image shows one end face of rotor 10, but on the other end face of rotor 10, it is also... Figure 1 The three separators 14 shown are arranged at the same positions. Through these separators 14, the rotor 10 is divided into three regions along its circumference. These three regions are a processing region A1, a regeneration region A2, and a cooling region A3.

[0030] The target gas is allowed to flow in processing zone A1. As the target gas passes through processing zone A1, the VOCs contained in it are adsorbed by the honeycomb structure 11, and the purified target gas is discharged from rotor 10. A high-temperature gas with a temperature higher than the boiling point of the VOCs flows in regeneration zone A2. As this high-temperature gas passes through regeneration zone A2, the VOCs adsorbed on the honeycomb structure 11 are detached from the honeycomb structure 11, and the gas containing the detached VOCs is discharged from rotor 10. Cooling gas used to cool the honeycomb structure 11 flows in cooling zone A3.

[0031] The rotor 10 rotates in the direction of arrow R to sequentially perform processing in processing area A1, regeneration area A2, and cooling area A3.

[0032] (Structure of a gas concentration unit)

[0033] Next, use Figures 2 to 6 The structure of the gas concentration apparatus is described below. The gas concentration apparatus 100, as described below, has a housing 1 and two chamber assemblies 2 and 3.

[0034] Box 1 has a rotor 10 and a housing 15 that houses the rotor 10. A drive unit for driving the rotor 10 is also housed in the housing 15. Figure 1 As shown (12, motor 13). Figure 2 as well as Figure 3 As shown, two openings 16 arranged along the Z-axis are formed on the side 15a of the housing 15. On the opposite side 15a, two openings 16 arranged along the Z-axis are also formed on the side 15a in the X-axis direction. These openings 16 serve as space for operations inside the housing 15. When the rotor 10 is operated, the openings 16 are sealed by a cover (not shown).

[0035] like Figure 3 as well as Figure 4 As shown, two chamber assemblies (first chamber assembly 2 and second chamber assembly 3) are respectively arranged on both sides of the box 1 in the Y-axis direction. The first chamber assembly 2 and the second chamber assembly 3 are configured to be separate from the box 1, and are connected to the box 1 by a connection structure described later. Through this connection structure, the first chamber assembly 2 and the second chamber assembly 3 are configured to be detached from the box 1.

[0036] Figure 5 This is the front view of the first chamber assembly 2, from... Figure 3 as well as Figure 4 The diagram shows the view of the first chamber assembly 2 when viewed in the direction of arrow Y1. (See image below.) Figure 5As shown, the first chamber assembly 2 has a housing 20, on which two intake ports (openings) 21 and 22 and an exhaust port (opening) 23 are formed.

[0037] The intake port 21 is used to guide the gas to be processed into the processing area A1 of the rotor 10 (see reference). Figure 1 The air intake 21 is located opposite the processing area A1 of the rotor 10 in the direction of the rotation axis of the rotor 10. A pipe (not shown) is provided outside the first chamber assembly 2, which is connected to the air intake 21 and is used to guide the gas to be processed to the air intake 21.

[0038] The intake port 22 is an opening for guiding cooling gas to the cooling region A3 of the rotor 10. The intake port 22 is located opposite the cooling region A3 of the rotor 10 in the direction of the rotor 10's rotation axis. A conduit (not shown) is provided inside the first chamber assembly 2 for guiding the gas drawn in from the intake port 22 to the cooling region A3, and a conduit (not shown) is provided outside the first chamber assembly 2 for connecting to the intake port 22 and guiding gas to the intake port 22.

[0039] The exhaust port 23 is an opening for discharging gas that has passed through the regeneration region A2 of the rotor 10. The exhaust port 23 is located opposite the regeneration region A2 of the rotor 10 in the direction of the rotor 10's rotation axis. Inside the first chamber assembly 2, a conduit (not shown) is provided for guiding the gas that has passed through the regeneration region A2 to the exhaust port 23, and outside the first chamber assembly 2, a conduit (not shown) is provided that connects to the exhaust port 23 and moves the gas discharged from the exhaust port 23.

[0040] In this embodiment, the intake port 21 is rectangular, and the intake port 22 and exhaust port 23 are circular, but other shapes are also possible. That is, as long as gas can pass through as described above, the shapes of the intake ports 21, 22 and exhaust ports 23 can be appropriately determined.

[0041] Figure 6 This is the front view of the second chamber assembly 3, from... Figure 3 as well as Figure 4 The diagram shows the view of the second chamber assembly 3 when viewed in the direction of arrow Y2. (See image below.) Figure 6 As shown, the second chamber assembly 3 has a housing 30, on which two exhaust ports (openings) 31 and 32 and an intake port (opening) 33 are formed.

[0042] Exhaust port 31 is used to discharge the wastewater that has passed through the processing area A1 of rotor 10 (see reference). Figure 1The exhaust port 31 is located opposite the processing area A1 of the rotor 10 in the direction of the rotor 10's rotation axis. A conduit (not shown) is provided outside the second chamber assembly 3 to connect to the exhaust port 31 and to move the gas discharged from the exhaust port 31.

[0043] The exhaust port 32 is an opening for discharging gas that has passed through the cooling region A3 of the rotor 10. The exhaust port 32 is located opposite the cooling region A3 of the rotor 10 in the direction of the rotor 10's rotation axis. Inside the second chamber assembly 3, a conduit (not shown) is provided for guiding the gas that has passed through the cooling region A3 to the exhaust port 32, and outside the second chamber assembly 3, a conduit (not shown) is provided that connects to the exhaust port 32 and moves the gas discharged from the exhaust port 32.

[0044] The intake port 33 is an opening for guiding high-temperature gas used to remove VOCs to the regeneration region A2 of the rotor 10. The intake port 33 is located opposite the regeneration region A2 in the direction of the rotation axis of the rotor 10. A conduit (not shown) for guiding high-temperature gas to the regeneration region A2 is provided inside the second chamber assembly 3, and a conduit (not shown) connected to the intake port 33 and used for guiding high-temperature gas to the intake port 33 is provided outside the second chamber assembly 3.

[0045] In this embodiment, the first chamber assembly 2 and the second chamber assembly 3 have the same structure. Specifically, by Figure 5 as well as Figure 6 It can be seen that the air intake 21 of the first chamber assembly 2 is equivalent to the air exhaust 31 of the second chamber assembly 3, the air intake 22 of the first chamber assembly 2 is equivalent to the air intake 33 of the second chamber assembly 3, and the air exhaust 23 of the first chamber assembly 2 is equivalent to the air exhaust 32 of the second chamber assembly 3.

[0046] In this embodiment, the exhaust port 31 is rectangular, and the exhaust port 32 and the intake port 33 are circular, but other shapes are also possible. That is, as long as gas can pass through as described above, the shapes of the exhaust ports 31, 32 and the intake port 33 can be appropriately determined.

[0047] Furthermore, the positions of the intake ports 21 and 22 and the exhaust port 23 in the housing 20 can be appropriately determined. For example, at least one of the intake port 22 and the exhaust port 23 can be provided on the upper surface or side surface of the housing 20 (the side surface that is in the same plane as the side surface 15a of the housing 15). The intake port 22 can be provided at any position as long as the cooling gas introduced from the intake port 22 can be guided to the cooling region A3 of the rotor 10. Similarly, the exhaust port 23 can be provided at any position as long as the gas passing through the regeneration region A2 of the rotor 10 can be guided to the exhaust port 23.

[0048] (Connection structure)

[0049] Next, the connection structure connecting box 1 to the first chamber assembly 2 or the second chamber assembly 3 will be described. The following is an example of such a connection structure. Figures 7 to 10 The structures shown are examples, but not limited to these structures. Additionally, in Figures 7 to 10 The connection between box 1 and the first chamber assembly 2 is described, but... Figures 7 to 10 The connection structure shown can also be applied to the case of connecting box 1 and second chamber assembly 3.

[0050] Since it is only necessary to connect the first chamber assembly 2 or the second chamber assembly 3 to the box 1, the location of the connection structure can be appropriately determined with this in mind. For example, the connection structure can be provided on the outer surface (bottom surface, upper surface, or side surface) of the first chamber assembly 2 or the second chamber assembly 3.

[0051] Figure 7 The connecting structure 40 shown has two brackets 41 and 42. The bracket 41 has a base portion 41a fixed to the housing 20 of the first chamber assembly 2 and a connecting portion 41b protruding from the base portion 41a. The bracket 42 has a base portion 42a fixed to the housing 15 of the box 1 and a connecting portion 42b protruding from the base portion 42a.

[0052] The two connecting parts 41b and 42b are in contact with each other and are clamped by a U-shaped clamping member 43. Openings for the shaft portion of the bolt 44 to pass through are formed in the connecting parts 41b and 42b and in the clamping member 43, and nuts 45 engage with the shaft portion of the bolt 44 that passes through these openings. By tightening the bolts 44 and nuts 45, which serve as fastening members, the connecting parts 41b and 42b can be fixed, thereby enabling the first chamber assembly 2 to be connected to the box 1.

[0053] according to Figure 7The connecting structure 40 shown, since the clamping member 43 surrounds the connecting portions 41b and 42b, can retain the leaked gas or liquid (hereinafter referred to as gas, etc.) from the box 1 and the first chamber assembly 2 in the space inside the clamping member 43, thereby suppressing the leakage of the gas or liquid to the outside of the clamping member 43.

[0054] Furthermore, the clamping member 43 can suppress light from entering the interior of the clamping member 43 from the outside. Thus, for example, even if a gap is formed between the connecting portions 41b and 42b, light can be prevented from reaching the coating formed on the housings 20 and 15 through the gap, thereby suppressing light-induced aging of the coating.

[0055] Furthermore, since the clamping member 43 is disposed between the head of the bolt 44 and the connecting portion 41b, or between the nut 45 and the connecting portion 42b, it functions as a washer when tightening the bolt 44 and the nut 45. Moreover, the clamping member 43 can function as both a washer (distributed between the head of the bolt 44 and the connecting portion 41b) and a washer (distributed between the nut 45 and the connecting portion 42b) within a single clamping member 43. Therefore, compared to installing washers separately, installation time can be reduced, or forgetting to install them can be prevented.

[0056] Furthermore, due to the space inside the clamping member 43, in the direction of overlap of the connecting portions 41b and 42b ( Figure 7 The specified distance is maintained in the left and right directions, so that when tightening the bolts 44 and nuts 45, the tightening force on the connecting parts 41b and 42b can be kept constant.

[0057] Figure 8 The connecting structure 50 shown has two brackets 51 and 52. The bracket 51 has a base portion 51a fixed to the housing 20 of the first chamber assembly 2, and a connecting portion 51b protruding from the base portion 51a. The bracket 52 has a base portion 52a fixed to the housing 15 of the box 1, and a connecting portion 52b protruding from the base portion 52a.

[0058] The connecting portions 51b and 52b each have an opening through which the shaft portion of the bolt 53 passes, and a nut 54 engages with the shaft portion of the bolt 53 passing through these openings. By tightening the bolt 53 and nut 54, which serve as fastening members, the connecting portions 51b and 52b can be fixed, thereby enabling the first chamber assembly 2 to be connected to the box 1.

[0059] according to Figure 8The connecting structure 50 shown has brackets 51 and 52 that are separate from the housings 20 and 15. Therefore, even if brackets 51 or 52 deform or break due to tightening of bolts 53 and nuts 54, only the deformed or damaged bracket needs to be replaced. This simplifies component replacement compared to directly tightening the housings 20 and 15, and reduces the cost of replacement components. Furthermore, by appropriately changing the shape and material of brackets 51 and 52, the connecting structure 50 can achieve desired functions (e.g., improved ease of installation in confined spaces, increased strength of the tightened parts).

[0060] Figure 9 The connecting structure 60 shown has a U-shaped connecting member 61 and two brackets 62 and 63. The connecting member 61 is disposed between the two brackets 62 and 63. The bracket 62 has a base portion 62a fixed to the housing 20 of the first chamber assembly 2 and a connecting portion 62b protruding from the base portion 62a. The bracket 63 has a base portion 63a fixed to the housing 15 of the box 1 and a connecting portion 63b protruding from the base portion 63a.

[0061] The connecting portion 62b of the bracket 62 contacts the connecting portion 61a of the connecting member 61 and is fixed by a bolt 64 and a nut 65. The shaft portion of the bolt 64 passes through the connecting portions 61a and 62b, and a nut 65 engages on the shaft portion of the bolt 64 that passes through the connecting portions 61a and 62b. By tightening the bolt 64 and the nut 65, which serve as fastening members, the bracket 62 and the connecting member 61 can be fixed, and the housing 20 of the first chamber assembly 2 can be fixed to the connecting member 61 via the bracket 62.

[0062] The connecting portion 63b of the bracket 63 contacts the connecting portion 61b of the connecting member 61 and is fixed by a bolt 66 and a nut 67. The shaft portion of the bolt 66 passes through the connecting portions 61b and 63b, and a nut 67 engages on the shaft portion of the bolt 66 that passes through the connecting portions 61b and 63b. By tightening the bolt 66 and the nut 67, which serve as fastening members, the bracket 63 and the connecting member 61 can be fixed, and the housing 15 of the box 1 can be fixed to the connecting member 61 via the bracket 63. By fixing the first chamber assembly 2 and the box 1 to the connecting member 61 respectively, the first chamber assembly 2 and the box 1 can be connected via the connecting member 61.

[0063] according to Figure 9The connecting structure 60 shown, because the connecting member 61 can seal the contact portion of the housings 15 and 20, can, for example, suppress leakage of gas or liquid (hereinafter referred to as gas, etc.) from the housing 1 and the first chamber assembly 2 from the contact portion of the housings 15 and 20, thereby suppressing the dispersion of gas, etc., to the outside of the connecting structure 60. Furthermore, when adhesive is applied to the contact portion of the housings 15 and 20, the adhesive may overflow from the contact portion, but the connecting member 61 can cover the overflow portion of the adhesive, thereby improving the aesthetic design. Further, by configuring the connecting member 61, light can be suppressed from entering the contact portion of the housings 15 and 20. Thus, light can be suppressed from reaching the coating formed on the contact portion of the housings 20 and 15, thereby suppressing light-induced aging of the coating.

[0064] By using two sets of bolts 64 and 66 and nuts 65 and 67, the strength of the connecting structure 60 can be improved. In addition, since a connecting member 61 is arranged between brackets 62 and 63, the spacing of brackets 62 and 63 (in other words, the position of each bracket 62 and 63) can be arbitrarily changed by using the connecting member 61 corresponding to the spacing of brackets 62 and 63.

[0065] Figure 10 The connecting structure 70 shown includes a connecting member 71 with a hollow structure and two brackets 72 and 73. The connecting member 71 is disposed between the two brackets 72 and 73. The bracket 72 has a base portion 72a fixed to the housing 20 of the first chamber assembly 2 and a connecting portion 72b protruding from the base portion 72a. The bracket 73 has a base portion 73a fixed to the housing 15 of the box 1 and a connecting portion 73b protruding from the base portion 73a.

[0066] The connecting portion 72b of bracket 72 contacts the connecting portion 71a of connecting member 71, and the connecting portion 73b of bracket 73 contacts the connecting portion 71b of connecting member 71. The shaft portion of bolt 74 passes through connecting portions 72b, 71a, 71b, and 73b, and a nut 75 engages on the shaft portion of bolt 74 passing through connecting portions 72b, 71a, 71b, and 73b. By tightening the bolt 74 and nut 75, which serve as fastening members, brackets 72 and 73 can be fixed to connecting member 71, thereby connecting the first chamber assembly 2 to the box 1 via connecting member 71.

[0067] according to Figure 10The connecting structure 70 shown, because the connecting member 71 can seal the contact portion of the housings 15 and 20, can, for example, suppress leakage of gas or liquid (hereinafter referred to as gas, etc.) from the housing 1 and the first chamber assembly 2 from the contact portion of the housings 15 and 20, thereby suppressing the dispersion of gas, etc., to the outside of the connecting structure 70. Furthermore, when adhesive is applied to the contact portion of the housings 15 and 20, the adhesive may overflow from the contact portion of the housings 15 and 20; however, by covering the overflow portion of the adhesive with the connecting member 71, the appearance design can be improved. Further, by configuring the connecting member 71, light can be suppressed from entering the contact portion of the housings 15 and 20. Thus, light can be suppressed from reaching the coating formed on the contact portion of the housings 20 and 15, thereby suppressing light-induced aging of the coating. Furthermore, since a connecting member 71 is arranged between brackets 72 and 73, the spacing of brackets 72 and 73 can be arbitrarily changed (in other words, the position of each bracket 72 and 73) by using the connecting member 71 corresponding to the spacing of brackets 72 and 73.

[0068] According to this embodiment, the cartridge 1, the first chamber assembly 2, and the second chamber assembly 3 are configured as separate units, thus allowing for individual replacement of these units. In conventional gas concentration devices, the cartridge and the two chamber assemblies are integrated, therefore, even if a part of the cartridge 1 fails, the entire gas concentration device must be replaced. According to this embodiment, if any unit of the cartridge 1, the first chamber assembly 2, or the second chamber assembly 3 fails, only the failed unit needs to be replaced, allowing continued use of the non-failed unit.

[0069] Furthermore, according to this embodiment, as described above, since the first chamber assembly 2 and the second chamber assembly 3 have the same structure, as long as a chamber assembly with this structure is manufactured, it can be used as the first chamber assembly 2 or as the second chamber assembly 3.

[0070] Furthermore, the first chamber assembly 2 and the second chamber assembly 3 may not have the same structure. Even if the first chamber assembly 2 and the second chamber assembly 3 have different structures, as described above, if any unit of the box 1, the first chamber assembly 2, or the second chamber assembly 3 fails, only the failed unit can be replaced.

[0071] As examples of the first chamber assembly 2 and the second chamber assembly 3 having different structures, the shapes of the intake port 21 and the exhaust port 31 can be different, or the position of the intake port 21 in the housing 20 can be different from the position of the exhaust port 31 in the housing 30. Furthermore, the shapes of the intake port 22 and the intake port 33 can be different, or the position of the intake port 22 in the housing 20 can be different from the position of the intake port 33 in the housing 30. Further, the shapes of the exhaust port 23 and the exhaust port 32 can be different, or the position of the exhaust port 23 in the housing 20 can be different from the position of the exhaust port 32 in the housing 30.

[0072] In this embodiment, the target gas, high-temperature gas, and cooling gas are subjected to... Figure 1 The gases flow in the directions shown, but are not limited to them; the flow directions of the target gas, high-temperature gas, and cooling gas can be appropriately determined. Depending on the flow directions of the target gas, high-temperature gas, and cooling gas, the functions (intake or exhaust) of the three openings 21, 22, and 23 provided in the first chamber assembly 2 and the three openings 31, 32, and 33 provided in the second chamber assembly 3 are different.
