2 to 4, the volatile organic compound removal system 1 according to an embodiment of the present invention receives an exhaust gas containing harmful components such as VOC and adsorbs harmful components contained in the exhaust gas (71 ) And then purify gas.

For example, the volatile organic compound removal system 1 according to an embodiment is connected to an exhaust gas inflow passage 12 and an exhaust gas inflow passage 12 connected to a pollutant that emits exhaust gas, and the exhaust gas inflow passage 12 ), the adsorption module for separating harmful components from the exhaust gas supplied through the main fan 14 and the main fan 14 and the adsorption module disposed in the exhaust gas inflow passage 12 to provide a flow force to the exhaust gas It is disposed in the exhaust gas inlet passage 12 and includes a main flow path damper 81 for opening and closing the exhaust gas inlet passage 12.

The volatile organic compound removal system 1 according to an embodiment may further include a bypass channel 15, a bypass damper 82, a control unit 200, a microwave, a catalyst module 60, and a cooling means. .

The adsorption module is connected to a pollution source to supply exhaust gas, and a space for removing harmful components from the exhaust gas is disposed therein. The adsorption module is connected to the exhaust gas inflow passage 12 to separate harmful components from the exhaust gas supplied through the exhaust gas inflow passage 12.

For example, the adsorption module is supplied through the exhaust gas inflow passage 12 connected to the exhaust gas inflow passage 12 and the exhaust gas inflow passage 12 connected to a rotating cartridge and a pollutant that discharges exhaust gas, and therein It may include an adsorption duct 10 on which the rotating cartridge 20 is located. The purge gas discharge channel is a purge gas discharged from the adsorption module. Specifically, the purification gas discharge flow path connects the outside air and the adsorption duct 10, and the purification gas from which harmful components are removed from the adsorption duct 10 is discharged.

The adsorption duct 10 is a space in which the rotating cartridge 20 is accommodated and harmful components are adsorbed to the adsorbent 71 of the rotating cartridge 20.

As the adsorbent 71, a material having an adsorption function and a heat storage function capable of adsorbing harmful components can be selected and used. For example, the adsorbent 71 is a cordierite material, a bent ceramic sheet, alumina, silica, a polymer resin, aluminum, stainless steel, asbestos, one material selected from the group consisting of natural fibers or between selected materials Composite material is used as heat storage material, and coated with 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, or a composite material between selected materials, or It may be constructed 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 composed of a core having a heat storage function and a coating layer having an adsorption function, as described later.

Zeolite is known as a three-dimensional inorganic polymer molecule in which silicon (Si) and aluminum (Al) are each connected through four crosslinked oxygen. Here, since aluminum has a negative charge as it is combined with four oxygens, various cations are present in the zeolite to counteract this charge. In detail, cations are present inside the pores, and the remaining spaces are usually filled with water molecules, and thus have relatively free mobility inside the pores and facilitate ion exchange with other cations. In addition, zeolites dehydrated by heating have the characteristic of filling the empty space by inhaling the empty space inside again by inhaling water molecules and other small molecules of a size capable of passing through the pore inlet, so that the dehydrated zeolite is an adsorbent ( 71), or it is often used as an absorbent. Typically, the zeolite is divided into β-zeolite, A-zeolite, ZSM-5 type zeolite, X-zeolite, Y-zeolite, or L-zeolite depending on the structure or the ratio of silicon to aluminum. In the present invention, a zeolite of a kind capable of easily adsorbing an adsorption target can be selected and used according to the use purpose of the adsorbent 71. Specifically, in one embodiment of the present invention, β-zeolite may be used as a volatile organic compound adsorption material, and Y-zeolite may be used as a water adsorption material.

The adsorbent 71 may be placed in the storage sector 20a in the form of an adsorption cartridge after molding into a reticular structure or a constant shape (corresponding to the storage section chin).

The desorption module is a flow path through which the harmful components are desorbed from the adsorbent 71 where the harmful components are adsorbed, and the concentrated gas enriched with the harmful components flows. The detachable module may be connected to at least one storage sector 20a of the rotating cartridge 20. For example, the detachable module further includes a detachable duct 30 formed to correspond to the at least one storage sector 20a and in contact with the boundary of the storage sector 20a to isolate the storage sector 20a.

The detachable duct 30 has a fan shape corresponding to the storage sector 20a when viewed from the top, and is formed to isolate at least one to preferably two storage sectors 20a from the outside. Specifically, the desorption duct 30 includes an upper desorption duct 310 sealing the upper portion of the storage sector 20a and a lower desorption duct 320 sealing the lower portion. The upper detachable duct 310 is in close contact with the upper surface of the storage sector 20a, and the lower detachable duct 320 is in close contact with the lower surface of the storage sector 20a. Of course, the upper detachable duct 310 and the lower detachable duct 320 may further include a packing made of a flexible material for enhancing the sealing force.

The desorption duct 30 is located inside the adsorption duct 10 and contacts the boundary of at least one storage sector 20a to seal between the adsorption duct 10 and the interior of the desorption duct 30. Of course, the detachable duct 30 has a structure that moves up and down, and may be opened or closed. When the desorption duct 30 is disposed inside the adsorption duct 10, there is an advantage of saving space in the system.

The desorption module may be connected to the catalyst module 60 for removing harmful components of the desorption gas. Specifically, the desorption module, one side is connected to the desorption duct 30, the other side is connected to the catalyst module 60, the first circulation flow path 32 to provide the desorption desorption gas to the catalyst module 60, one side This catalyst module 60 is connected to the other side is connected to the desorption duct 30, a second circulation passage 31 through which a part of the air from which the harmful components are removed from the catalyst module 60 is supplied back to the desorption duct 30 And, it is connected to the catalyst module 60 may further include a discharge passage 33 through which the air from which harmful components are removed is discharged to the outside.

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

It is preferable that the amount of air supplied through the desorption module is smaller than the amount of air supplied through the adsorption module. Generally, 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 stored in the adsorbent 71 during desorption. Specifically, the size of the desorption duct 30 is smaller than the adsorption duct 10, the desorption duct 30 has a size corresponding to one to two storage sectors 20a, and the adsorption duct 10 is ten. It has a size corresponding 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 can be performed by heating the adsorbent 71 with microwaves. The embodiment further includes a microwave generator 50 that supplies microwaves to the adsorbent 71 in the desorption duct 30.

The microwave generator 50 may be disposed inside or outside the adsorption duct 10.

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

To reduce energy by using waste heat, and for effective desorption and decomposition of harmful components, the catalyst module 60 heats the air supplied from the desorption module, decomposes the harmful components, and desorbs the heat of the decomposed harmful components. It can be delivered to the adsorbent 71 in the module. In addition, the catalyst module 60 may transfer heat of the air in which harmful components are decomposed to the concentrated gas discharged from the desorption module, thereby reducing heat provided for the catalytic reaction.

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 is to decompose by oxidizing harmful components, and may be selected from zeolite, alumina (Al2O3), activated carbon, and mixed oxide metal. The catalyst cartridge 62 may be an oxide-like molded body capable of oxidizing harmful components.

The heater 61 heats the concentrated gas supplied from the desorption module to the catalyst module. Various heaters may be used as the heater 61.

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) uses the waste heat of the air before discharge to the outside to heat the concentrated gas. 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 air passing through the catalyst cartridge 62 and air supplied into the desorption duct 30. A plurality of heat exchangers 63 and 65 may be provided.

A portion of the air that has passed through the heat exchangers (63, 65) is discharged to the outside through the discharge flow path (33), or another portion flows back to the adsorption duct (10) through the second circulation flow path (31).

The circulation fan 64 provides a flow force to the 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 it is difficult to adsorb harmful components in the exhaust gas, it can be cooled by supplying external air from the cooling means.

The cooling means may have various configurations for supplying external air to the adsorbent 71 from which harmful components are desorbed. In addition, the cooling means may be configured such that the cooling air that cools the adsorbent 71 from which harmful components are desorbed is discharged directly to the outside or discharged to the outside through the catalyst module 60.

The effluent air discharged from the cooling means is heat-exchanged with the air supplied into the desorption duct 30 and is supplied to transfer heat to the adsorbent 71.

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

Specifically, the cooling means, one side is connected to the outside air, the other side is connected to the desorption duct 30, the outside air passage 41, one side is connected to the desorption duct 30, the other side is connected to the catalyst module 60 It includes a cooling flow path 42.

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

In addition, the intermittent intermittent valves 71 and 73 may be disposed in each flow path. Specifically, the intermittent valves 71 and 73 are disposed in the adsorption module, the desorption module, and the cooling passage 42, respectively. These intermittent valves 71 and 73 may be closed when the rotating cartridge 20 is rotated and opened when it is stopped.

5 is a view showing a state in the VOC removal operation of the volatile organic compound removal system according to an embodiment of the present invention, Figure 6 is a volatile organic compound removal system according to an embodiment of the present invention during maintenance or repair operation It is a figure showing the appearance on.

2 to 6, one end of the exhaust gas inflow passage 12 is connected to a pollution source and the other end is connected to an adsorption duct 10. The main fan 14 is provided to provide exhaust gas flow to the exhaust gas inflow passage, adsorption duct, and purge gas discharge passage.

When the main fan 14 is disposed downstream of the adsorption module, there is a fear that the inside of the adsorption module is negatively pressured and external air is introduced into the inside. Therefore, the main fan 14 can be disposed upstream of the adsorption module. Specifically, the main fan 14 may be disposed in the exhaust gas inflow passage 12. Preferably, it may be disposed upstream of the main flow path damper 81 on the exhaust gas inflow passage 12.

The main flow path damper 81 regulates the exhaust gas flowing from the exhaust gas inflow passage 12 to the adsorption module. The main flow path damper 81 is disposed in the exhaust gas inflow passage 12 between the main fan 14 and the adsorption module to open and close the exhaust gas inflow passage 12. More specifically, the main flow path damper 81 may be disposed in the exhaust gas inflow path 12 between the main fan 14 and the adsorption duct.

The main flow path damper 81 may be implemented by various known technologies, and may include, for example, a rotating plate and a driving motor rotating the same. The main flow damper 81 is opened when the volatile organic compound removal system is in operation to remove VOCs, and is closed during maintenance of the volatile organic compound removal system.

The bypass passage 15 does not stop the main fan 14 during maintenance of the volatile organic compound removal system, and bypasses the harmful gas introduced from the exhaust gas inflow passage 12. The bypass flow passage 15 connects the exhaust gas inflow passage 12 and the purified gas exhaust flow passage. Specifically, the bypass flow passage 15 is connected to the upstream of the main flow path damper 81 in the inflow passage of the exhaust gas, and is connected to the downstream of the main fan 14. More specifically, the bypass flow path 15 is connected between the main flow path damper 81 and the main fan 14 in the exhaust gas inflow path 12.

The bypass damper 82 interrupts the exhaust gas flowing from the bypass channel 15 to the adsorption module. The bypass damper 82 is disposed in the bypass channel 15 to open and close the bypass channel 15.

Bypass damper 82 may be implemented in a variety of known techniques, for example, may include a rotating plate and a driving motor for rotating it. The bypass damper 82 is closed when the volatile organic compound removal system is in a VOC removal operation, and is opened during maintenance of the volatile organic compound removal system.

The control unit 200 may control the main flow path damper 81 and the bypass damper 82. Specifically, when the main flow path damper 81 is opened, the control unit 200 may close the bypass damper 82. That is, when the volatile organic compound removal system is in the VOC removal operation, the control unit 200 opens the main flow path damper 81 and closes the bypass damper 82. At this time, the main fan 14 is operating. Therefore, in the volatile organic compound removal system, harmful gases are purified and discharged, not discharged to outside air.

When closing the main flow path damper 81, the control unit 200 may open the bypass damper 82. That is, the control unit 200 maintains the operation of the main fan 14 when the volatile organic compound removal system is in maintenance or maintenance, closes the main flow path damper 81, and opens the bypass damper 82. . Therefore, the harmful gas discharged from the inside of the process flows through the bypass flow path 15 to the purified gas outlet flow path.

When the main flow path damper 81 is closed, the control unit 200 may adjust the number of revolutions of the main fan 14. Specifically, the control unit 200 measures the air pressure in the process when the main flow path damper 81 is closed, and the air pressure is rotated by the main fan 14 similarly to the case where the main flow path damper 81 is opened. You can increase or decrease the number.

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

7 is a view showing a rotating cartridge 20 according to an embodiment of the present invention, Figure 8 is a cross-sectional view taken along the line A-A of FIG.

2 to 8, the rotating cartridge 20 is configured to be rotatable, so that the adsorbent 71 stored in each of the plurality of storage sectors 20a circulates the adsorption module and the desorption module.

The rotating cartridge 20 is divided into a plurality of regions and has a plurality of storage sectors 20a for receiving the adsorbent 71. For example, the rotating cartridge 20 may include a rotating shaft 23, a main body 21, and a plurality of partition walls 22.

The rotating shaft 23 transmits the driving force of the driving unit. The rotating shaft 23 is connected to the driving unit.

The body 21 has a structure in which air can be introduced and adsorbed and discharged by the adsorbent 71. The body 21 has a space for receiving the adsorbent 71 cartridge therein. The main body 21 has an air inlet 24 through which air flows into the upper portion, and an air outlet 25 through which air flows into the lower portion. The air inlet 24 and the air outlet 25 of the body 21 may have a completely open shape, but in order to prevent separation of the adsorption cartridge 70 stored inside the body 21, a mesh structure is used. It is desirable to have.

The shape of the main body 21 is preferably a cylindrical shape with the rotating shaft 23 of the rotating cartridge 20 as a central axis. 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 partition walls 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 rotating shaft 23 of the rotating cartridge 20 and are connected to the main body 21. That is, the plurality of partition walls 22 have a shape extending radially from the rotation shaft 23 of the rotating cartridge 20.

When the shape and size of each storage sector 20a are different from each other, when the rotating cartridge 20 is rotated, since each storage sector 20a cannot be sealed with the detachable duct 30, it is difficult to remove harmful components, and thus a plurality of It is preferable that the storage sectors 20a have the same shape.

Specifically, each storage sector 20a has two strings (partition 22) formed around the rotating shaft 23 of the rotating cartridge 20 and two arcs connecting the two strings (some areas of the body 21) ). At this time, the fan angles θ of the plurality of storage sectors 20a are formed to be the same as each other. Between the plurality of storage sectors (20a) may be sealed so that the air does not pass through each other.

In addition, a window through which microwaves pass may be formed in the body 21. The window is formed in a mesh structure, and may be provided in each storage sector 20a.

A plurality of rotating cartridges 20 may be stacked and disposed along the flow direction of the exhaust gas. Of course, the type of the adsorbent 71 filled in the plurality of rotating cartridges 20 may be different from each other.

The driving unit (not shown) rotates the rotating cartridge 20 so that the plurality of storage sectors 20a are moved in the order of the adsorption module to which harmful components are supplied, and the desorption module to which the harmful components adsorbed on the adsorbent 71 are detached and flow. 3, the driving unit rotates the rotating cartridge 20 counterclockwise and stops.

The driving unit rotates the rotating cartridge 20 by a predetermined rotation angle and then stops for a predetermined time. At this time, it is preferable that the preset rotation angle is the same as the fan-shaped angle of each storage sector 20a. While the rotary cartridge 20 is stationary, harmful components are adsorbed by the adsorbent 71 in the adsorption duct 10, and harmful components are desorbed by the adsorbent 71 in the desorption duct 30.

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

Although not shown in the drawing, the overall control of the volatile organic compound removal system may further include a control unit 200 for controlling the operation. The control unit 200 may control the driving unit and each of the intermittent valves 71 and 73.

The control unit 200 may close each of the intermittent valves 71 and 73 while the driving unit is operating, and open each of the intermittent valves 71 and 73 while the driving unit is stopped.
