1 to 4, the volatile organic compound removal device 1 according to an embodiment of the present invention receives an exhaust gas containing harmful components such as VOCs and absorbs harmful components contained in the exhaust gas. After adsorption, the purge gas is discharged.

For example, the volatile organic compound removal device 1 according to an embodiment includes an adsorption module 10 and 12 receiving an exhaust gas containing harmful components such as VOCs, an adsorption function capable of adsorbing harmful components, and heat storage. The adsorbent 71 having a function at the same time, the rotary cartridge 20 having a plurality of storage sectors 20a which are divided into a plurality of areas to accommodate the adsorbent 71, and the harmful components adsorbed by the adsorbent 71 flow by desorbing. And a driving unit for rotating the detachable module and the rotating cartridge 20.

The volatile organic compound removal device 1 according to an embodiment may further include a microwave generator, a catalyst module 60 and cooling means.

Adsorption modules 10 and 12 are connected to a pollution source to supply exhaust gas, and a space is disposed therein to remove harmful components from the exhaust gas.

For example, the exhaust gas inflow passage 12 and the exhaust gas inflow passage 12 connected to the polluting source for exhausting the exhaust gas are supplied through the exhaust gas inflow passage 12, and a rotating cartridge 20 is provided therein. The adsorption duct 10 may be located. The adsorption duct 10 is connected to a purge gas discharge passage 13 through which the purge gas from which noxious components have been removed from the adsorption duct 10 is discharged. Adsorption modules 10 and 12 are provided with a main fan 14 to provide flow force to the exhaust gas.

The adsorption duct 10 accommodates the rotary cartridge 20 therein and is a space in which harmful components are adsorbed by the adsorbent 71 of the rotary cartridge 20.

The adsorbent 71 may be selected and used as a material having an adsorption function and a heat storage function capable of adsorbing harmful components. For example, the adsorbent 71 may be formed of a cordierite material, a bent ceramic sheet, alumina, silica, a polymer resin, aluminum, stainless steel, asfest, or a material selected from the group consisting of natural fibers. The composite material is used as a heat storage material and a coating material of one or a selected material selected from the group consisting of zeolite, activated carbon, activated carbon fiber, alumina, silica, photocatalyst and low temperature oxidation catalyst with adsorption function It may consist of one prepared by adding both. Of course, the adsorbent 71 may be made of one material selected from the group consisting of zeolite, activated carbon, activated carbon fiber, alumina, silica, photocatalyst and low temperature oxidation catalyst having adsorption function. Preferably, the adsorbent 71 may be configured to include a core having a heat storage function and a coating layer coating the core and having an adsorption function as described below.

Zeolites are known as three-dimensional inorganic algae molecules in which silicon (Si) and aluminum (Al) are each connected through four bridged oxygens. Here, since aluminum has a negative charge as it combines with four oxygens, various cations exist in the zeolite to offset this charge. Specifically, the cations are present in the pores and the remaining spaces are usually filled with water molecules, so that they have relatively free mobility in the pores, and are easily ion exchanged with other cations. In addition, the heated and dehydrated zeolites have a characteristic of filling the empty space by sucking the small molecules of the size that can pass through the pore inlet to the empty space inside the water again. 71) or as an absorbent. Zeolites are generally divided into β-zeolites, A-zeolites, ZSM-5 zeolites, X-zeolites, Y-zeolites, or L-zeolites, depending on the structure or the ratio of silicon to aluminum. In the present invention, a zeolite of a kind capable of easily adsorbing the adsorption target can be selected and used depending on the intended use of the adsorbent 71. Specifically, in an embodiment of the present invention, β-zeolite may be used as the volatile organic compound adsorption material, and Y-zeolite may be used as the moisture adsorption material.

The adsorbent 71 may be formed into a network structure or a predetermined shape (corresponding to the storage sector) and then positioned in the storage sector 20a in the form of an adsorption cartridge.

The desorption module is a flow path through which the harmful components are desorbed from the adsorbent 71 to which the harmful components are adsorbed and the concentrated gas in which the harmful components are concentrated is flowed. The detachable module may be connected to at least one storage sector 20a of the rotating cartridge 20. For example, the desorption module is formed to correspond to at least one storage sector 20a, is in contact with the boundary of the storage sector 20a to isolate the storage sector 20a, and the storage sector 20a together with the desorption space ( It further includes a detachable duct 30 defining 301. The detachable duct 30 will be described later with reference to FIG. 6.

 The desorption module may be connected to the catalyst module 60 for removing harmful components of the desorption gas. Specifically, the desorption module has one side connected to the desorption duct 30, the other side is connected to the catalyst module 60, the first circulation passage 32 for providing the desorbed desorption gas to the catalyst module 60, and one side The second circulation passage 31 is connected to the catalyst module 60 and the other side is connected to the desorption duct 30 so that a part of the air from which harmful components have been removed from the catalyst module 60 is supplied back to the desorption duct 30. And, connected to the catalyst module 60 may further include a discharge passage 33 for discharging the air from which harmful components have been removed.

The air supplied through the second circulation passage 31 may receive heat from the catalyst module 60 or heat from cooling means described later to save desorption energy.

The amount of air supplied through the desorption module is preferably smaller than the amount of air supplied through the adsorption modules 10 and 12. In general, 1/5 to 1/20 is preferred. At this time, the desorption time and method should be properly determined so that there is no loss of energy accumulated in the adsorbent 71 during desorption. Specifically, the size of the desorption duct 30 is smaller than that of the adsorption duct 10, and the desorption duct 30 has a size corresponding to 1 to 2 storage sectors 20a, and the adsorption duct 10 has 10 sizes. To 40 storage sectors 20a.

The adsorbent 71 in the desorption duct 30 is desorbed using temperature, pressure, light energy or sound wave energy. Preferably, the desorption in the desorption module may be performed by heating the adsorbent 71 with microwaves. The embodiment further includes a microwave generator 50 for supplying microwaves to the adsorbent 71 in the desorption duct 30.

The catalyst module 60 decomposes harmful components concentrated in the air supplied from the desorption module. Decomposed harmful components are discharged to the outside by a separate device. The air from which harmful components have been removed from the catalyst module 60 may be circulated again and supplied to the inside of the desorption duct 30.

In order to reduce energy by utilizing waste heat, and to effectively desorb and decompose harmful components, the catalyst module 60 heats the air supplied from the desorption module, decomposes harmful components, and desorbs heat of decomposed air. It can be delivered to the adsorbent 71 in the module. In addition, the catalyst module 60 may reduce the heat provided to the catalytic reaction by transferring the heat of the air from which the harmful components are decomposed to the concentrated gas discharged from the desorption module.

Specifically, the catalyst module 60 may include a catalyst cartridge 62, heat exchangers 63 and 65, a circulation fan 64, and a heater 61.

The catalyst cartridge 62 oxidizes and decomposes harmful components, and may be selected from zeolite, alumina (Al ₂ O ₃ ), activated carbon, and mixed oxide metal. The catalyst cartridge 62 may be an oxidized molded body capable of oxidizing harmful components.

The heater 61 heats the concentrated gas supplied from the desorption module to the catalyst module. The heater 61 may use various heating means.

The heat exchangers 63 and 65 exchange heat between the concentrated gas supplied from the desorption duct 30 and the air passing through the catalyst cartridge 62. The first heat exchanger (63, 65) heats the concentrated gas using the waste heat of the air before discharge to the outside. Therefore, the first heat exchangers 63 and 65 can reduce energy for heating the concentrated gas.

In addition, the heat exchangers 63 and 65 may exchange heat between the air passing through the catalyst cartridge 62 and the air supplied into the desorption duct 30. The heat exchangers 63 and 65 may be provided in plural numbers.

Some of the air passing through the heat exchangers (63, 65) is discharged to the outside through the discharge passage 33, or the other portion is flowed back to the adsorption duct 10 through the second circulation passage (31).

The circulation fan 64 provides flow force to air flowing through the desorption module and the catalyst module 60.

The cooling means cools the adsorbent 71 heated in the desorption module. In the case of the heated adsorbent 71, since harmful components are hardly adsorbed in the exhaust gas, it is possible to cool by supplying external air from the cooling means.

The cooling means may have various configurations to supply external air to the adsorbent 71 from which harmful components are desorbed. In addition, the cooling means may be configured to directly discharge the cooling air cooling the adsorbent 71 from which the harmful components are desorbed to the outside, or to the outside through the catalyst module 60.

The outflow air discharged from the cooling means may be heat exchanged with the air supplied into the desorption duct 30 to supply heat to the adsorbent 71.

The cooling means may have a separate cooling space for accommodating the storage sector 20a, or may be connected to the removable duct 30 and may not have a separate cooling space as in the embodiment.

Specifically, the cooling means is one side is connected to the outside air and the other side is connected to the removable air duct (30), the other side is connected to the removable duct 30, the other side is connected to the catalyst module 60 And a cooling passage 42 to be used.

The cooling passage 42 and the outside air passage 41 are disposed ahead of the first and second circulation passages 31 in the rotational direction of the rotary cartridge 20. Therefore, the adsorbent 71 in which desorption is completed can be cooled effectively.

In addition, intermittent valves 71, 72, and 73 may be disposed in each flow path to control the flow of air. Specifically, the intermittent valves 71, 72, and 73 are disposed in the adsorption modules 10 and 12, the desorption module, and the cooling passage 42, respectively. These intermittent valves 71, 72, 73 may be closed when the rotating cartridge 20 is rotated and open when stopped.

Hereinafter, the structure and operation of the rotary cartridge 20 will be described in detail.

5 is a view showing a rotary cartridge 20 according to an embodiment of the present invention, Figure 6 is a cross-sectional view showing a state in which the removable duct 30 and the rotary cartridge 20 in contact.

1 to 6, the rotating cartridge 20 is configured to be rotatable, so that the adsorbents 71 respectively stored in the plurality of storage sectors 20a circulate the adsorption modules 10 and 12 and the desorption module. .

The rotary cartridge 20 has a plurality of storage sectors 20a which are partitioned into a plurality of regions to accommodate the adsorbent 71. For example, the rotating cartridge 20 may include a hub 23, a main body 21, and a plurality of partitions 22.

Hub 23 is coupled to the rotation axis. It transmits the driving force of the rotating shaft drive unit. The hub 23 is connected by a drive unit and a rotating shaft. Specifically, the hub 23 has a structure in which a hole in which the rotation shaft is inserted is formed.

The main body 21 has a structure in which air is introduced to be adsorbed and discharged by the adsorbent 71. The main body 21 has a space for accommodating the adsorbent 71 cartridge therein. The main body 21 has a structure opened up and down.

It is preferable that the shape of the main body 21 is cylindrical shape centering on the hub 23 of the rotating cartridge 20. As shown in FIG. This is because the shape of the storage sector 20a does not change even when the rotating cartridge 20 is rotated, so that it is easy to seal with the detachable duct 30.

The plurality of partitions 22 divide the internal space of the main body 21 into a plurality of storage sectors 20a. The plurality of partition walls 22 extend radially from the hub 23 of the rotating cartridge 20 to be connected to the main body 21. That is, the plurality of partitions 22 have a shape extending radially from the hub 23 of the rotary cartridge 20.

When the shape and size of each of the storage sectors 20a are different from each other, when the rotating cartridge 20 is rotated, the storage sectors 20a are not sealed with the desorption duct 30, so that desorption of harmful components is difficult. The storage sectors 20a preferably have the same shape.

Specifically, each of the storage sectors 20a includes two strings (partitioning walls 22) formed around the hub 23 of the rotating cartridge 20 and an arc connecting the two strings (part of the main body 21). It has a fan shape defined by. At this time, the sector angle θ of the plurality of storage sectors 20a is formed to be the same. The plurality of storage sectors 20a may be sealed to prevent air from passing through each other by the sealing member 350 to be described later.

In addition, a window through which the microwave passes may be formed in the main body 21. The window has a mesh structure and may be provided in each storage sector 20a.

Rotating cartridge 20 may be arranged in a plurality of stacked along the flow direction of the exhaust gas. Of course, the type of adsorbent 71 filled in the plurality of rotating cartridges 20 may be different.

Each storage sector 20a has an air inlet 24 through which air flows in the upper portion, and an air outlet 25 through which air flows out in the lower portion.

The air inlet 24 and the air outlet 25 of the storage sector 20a may have a completely open shape, but in order to prevent separation of the adsorption cartridge 70 stored inside the storage sector 20a, the mesh It is desirable to have a structure.

More preferably, the air inlet 24 and the air outlet 25 of the storage sector 20a may be a porous plate.

The driving unit (not shown) rotates the cartridge 20 so that the plurality of storage sectors 20a are moved in the order of the adsorption modules 10 and 12 to which noxious components are supplied, and the desorption module to which noxious components adsorbed to the adsorbent 71 are desorbed and flowed. Rotate). Referring to FIG. 2, the drive unit rotates the rotation cartridge 20 counterclockwise and stops it.

The driving unit rotates the rotation cartridge 20 by a predetermined rotation angle and then rotates to stop for a predetermined time. At this time, the preset rotation angle is preferably the same as the fan-shaped angle of each storage sector (20a). While the rotary cartridge 20 is stopped, noxious components are adsorbed in the adsorbent 71 in the adsorption duct 10, and noxious components are desorbed in the adsorbent 71 in the desorption duct 30.

The driving unit rotates the rotary cartridge 20 so that each storage sector 20a circulates the adsorption duct 10 and the detachment duct 30, and the boundary of each storage sector 20a and the detachment duct 30 correspond to each other. The rotary cartridge 20 is stopped in position so that some of the storage sectors 20a are isolated from the adsorption duct 10 inside the removable duct 30.

Although not shown in the figure, it may further include a control unit for controlling the overall operation of the volatile organic compound removal system. The control unit may control the driving unit and each of the control valves 71, 72, and 73.

The control unit may close each of the control valves 71, 72, and 73 while the driving unit is in operation, and open each of the control valves 71, 72, and 73 while the driving unit is stopped.

6 is a cross-sectional view showing a state in which the detachable duct and the rotary cartridge contact, FIG. 7 is a cross-sectional view taken along the line A-A of FIG. 3, and FIG. 8 is a view showing the upper detachable duct according to an embodiment of the present invention.

In particular, referring to FIGS. 6 to 8, the detachable duct 30 has a fan shape corresponding to the storage sector 20a when viewed from the top, and at least one to preferably two storage sectors 20a are formed. It is formed to be isolated from the outside.

Specifically, the detachable duct 30 includes an upper detachable duct 310 covering an upper portion of the storage sector 20a and a lower detachable duct 320 covering the lower portion.

The upper desorption duct 310 is in close contact with the upper surface of the storage sector (20a) to seal the air inlet 24, the lower desorption duct 320 is in close contact with the lower surface of the storage sector (20a) air outlet 25 Seal it.

The upper detachable duct 310 may be positioned on the upper surface of the rotary cartridge 20, and the lower detachable duct 320 may be positioned on the lower surface of the rotary cartridge 20. Specifically, when the upper detachable duct 310 and the lower detachable duct 320 contact the air inlet 24 or the air outlet 25 of the storage sector 20a of the rotary cartridge 20, the detachable space 301 is formed. It is not sealed to the outside space.

Accordingly, the upper detachable duct 310 is in contact with the upper end of the partition 22, the upper end of the hub 23, and the upper end of the body 21, and the lower detachable duct 320 is the lower end of the partition 22, the hub 23. Bottom end of the main body 21 and the lower end of the main body 21. Accordingly, the detachable space 301 may include a partition wall 22, a hub 23, which is in contact with the upper detachable duct 310, the lower detachable duct 320, the upper detachable duct 310, and the lower detachable duct 320. It becomes the space defined by the main body 21.

The detachable space 301 forms a space in the upper or lower portion of the storage sector 20a, so that the microwaves provided into the detachable duct 30 can be easily transferred.

The upper detachable duct 310 and the lower detachable duct 320 have an open shape to one side. The upper detachable duct 310 and the lower detachable duct 320 may include a duct cover 311 and a rim 313 extending from an edge of the duct cover 311 to define an opening.

The duct cover 311 covers the top or bottom of the at least one storage sector 20a. Specifically, the duct cover 311 has a fan shape covering one storage sector 20a or a plurality of storage sectors 20a.

The rim 313 extends in the direction crossing the duct cover 311 at the edge of the duct cover 311. Rim 313 is spaced between the duct cover 311 and the rotating cartridge (20). Rim 313 is in contact with the rotating cartridge 20 on one surface.

The desorption duct 30 is located inside the adsorption duct 10 and contacts the boundary of the at least one storage sector 20a to seal between the adsorption duct 10 and the interior of the desorption duct 30. The desorption space 301 is a space formed inside the adsorption duct 10. If the detachable duct 30 is disposed inside the adsorption duct 10, there is an advantage of saving space in the system.

The detachable duct 30 has a structure that is moved up and down, and may be opened or closed. Specifically, the upper detachable duct 310 and the lower detachable duct 320 may further include a moving means (not shown) for moving in the vertical direction. The moving means may include a rack and a gear for moving the upper and lower detachment ducts 310 and the lower detachment ducts 320 up and down, or racks and screws, cylinders and pistons, and the like.

The microwave generator 400 is coupled to the detachment duct 30 to provide microwaves in the detachment space. When the microwave generator 400 is coupled to the rotary cartridge, it is possible to solve the problem of detachment and leakage occurring, and the volume of the rotary cartridge increases.

When the microwave generator 400 is coupled to the detachable duct 30, the microwave generator 400 is constrained by the movement of the detachable duct 30 and moved together so that a separate driving unit is not required.

Specifically, the microwave generator 400 is coupled to one surface of the detachable duct 30. For example, the microwave generator 400 may be coupled to one side of the tapping duct. The microwave generator 400 may be coupled to the rim 312.

At this time, the microwave generator 400 may oscillate the microwave in the horizontal direction. The horizontal plane (duct cover 311) of the detachable duct 30 is spaced apart from the adsorbent contained in the rotary cartridge to define the detachable space 301, and the microwaves propagate to the detachable space 301 in the horizontal direction, so that the entire absorbent is absorbed. Can be heated evenly.

The microwave generator 400 includes a magnetron 410 for generating microwaves, and a waveguide 420 for guiding microwaves oscillated from the magnetron 410 to a detachment space.

The waveguide 420 may be connected to one surface of the detachable duct 30. Specifically, in the present embodiment, the waveguide 420 may be coupled to the rim 312 of the detachable duct 30 and may have a microwave outlet open in the direction of the rim 312. The microwave outlet may be open, or a filter made of a material (for example, a mica membrane) through which microwaves may be disposed may be further disposed.

The detachable duct 30 may have a window window 312a through which the microwaves oscillated by the microwave generator 400 pass. The window 312a may be in communication with the microwave outlet of the waveguide 420.

The rotary cartridge 20 and the detachable duct 30 are made of metal material to prevent leakage of rigidity and microwaves. When the rotary cartridge 20 and the detachable duct 30 are made of a metal material, even when the rotary cartridge 20 and the contact duct come into contact with each other, microwaves may leak or desorbed desorbed gas may flow between them.

If the microwave leaks, noise is generated in the equipment, various sensors, and the communication equipment, thereby disturbing the control and disturbing the operation of the equipment.

In addition, when using a silicone-based sealing material to prevent the outflow of the desorption gas between the rotary cartridge 20 and the desorption duct 30, there is a problem that is cured by the microwave.

Therefore, in the present invention, in order to prevent leakage of the microwaves and the desorption gas in the desorption space 301 and to prevent hardening of the sealing material, a sealing member 350 for sealing the desorption space 301 is provided.

The sealing member 350 is disposed between the rotary cartridge 20 and the detachable duct 30 to seal the detachable space 301.

If the sealing member 350 is a single silicon-based structure, the leakage of microwaves cannot be prevented and hardened to leak desorbed gas therein, and if the single metal-based structure prevents the leakage of microwaves, It is weak and can not prevent leakage of desorption gas.

Therefore, the sealing member 350 of the embodiment applies a dual structure of different materials.

For example, the sealing member 350 may include a first packing 351 and a second packing 352 of a different material from the first packing 351.

The first packing 351 and the second packing 352 form a closed loop. That is, the first packing 351 and the second packing 352 have a ring shape.

Specifically, the first packing 351 and the second packing 352 are disposed between the lower end of the rim 313 of the upper detachable duct 310 and the upper end of the rotary cartridge 20, the first packing 351 and The second packing 352 is disposed between the top of the rim 313 of the lower detachment duct 320 and the bottom of the rotary cartridge 20.

The first packing 351 and the second packing 352 are coupled to each removable duct 30. The first packing 351 and the second packing 352 are coupled to the lower end of the rim 313 of each detachable duct 30.

The first packing 351 is disposed closer to the center of the detachable space 301 than the second packing 352. The second packing 352 surrounds the first packing 351 from the outside.

The first packing 351 may include a conductive material, and the second packing 352 may include a rubber or resin material. The first packing 351 is a metal material, but the sealing force is reduced, but can effectively block the microwave, the second packing 352 can be cured by the microwave, but the flexible material is excellent in the sealing force.

If the first packing 351 is a conductive material, it is possible to block microwaves radiated from the inside of the detachable duct 30, to prevent the microwaves from going to the second packing 352, and the second packing 352. Blocks the desorption gas leaking into the first packing 351 from leaking outside.

Therefore, the sealing member 350 of the embodiment may have a dual structure to prevent the outflow of the desorption gas, to prevent the outflow of the microwave, and to prevent the hardening of the second packing 352.

The first packing 351 may include a conductive material to block microwaves. For example, the first packing 351 may include a conductive metal and a conductive polymer. Preferably, the material of the first packing 351 is metal.

In order to improve the packing force of the first packing 351, the first packing 351 may have a mesh structure, a spiral structure, and a finger structure. Since the mesh structure, the spiral structure, and the finger structure are formed of a conductive material and an empty space, when the first packing 351 is in close contact with the rotary cartridge 20, the adhesion is improved while being deformed. The finger structure will be described later.

The second packing 352 is made of an elastic force or a flexible rubber or resin material. Preferably, the second packing 352 may include a silicon-based material. Silicone-based materials have excellent versatility and excellent sealing power.
