Description

Microwave dehumidification system

[0001] The present invention relates to a dehumidification system using microwaves.

[0002] Processes such as painting, battery manufacturing, semiconductor manufacturing, and petrochemical processes are sensitive to humidity and contaminants, and it is necessary to provide an optimal process environment by removing moisture and contaminants from the air flowing into the process space from the outside. In particular, a dehumidification system is being introduced to maintain the humidity in the process space.

[0003] Dehumidification systems can be categorized into refrigeration, compression, and adsorption types based on their dehumidification method. Refrigeration dehumidification methods, however, suffer from the disadvantages of increased costs due to the compressor required to compress the refrigerant, as well as significant noise and space consumption. Compression dehumidification methods, on the other hand, require excessive power, limiting their use to specialized applications. Therefore, adsorption dehumidification has been used in various industries to address the shortcomings of refrigeration and compression dehumidification methods.

[0004] Adsorption dehumidification is a method of removing moisture from the air by passing air through a dehumidifying rotor filled with a desiccant (e.g., silica gel or zeolite), so that moisture in the air is absorbed by the desiccant. A typical adsorption dehumidification method includes a dehumidification process in which the dehumidifying rotor absorbs moisture from the process air to be dried, and a regeneration process in which the dehumidifying rotor is regenerated by drying or dehumidifying the desiccant absorbed through the dehumidification process, so that the dehumidifying rotor can continuously perform its dehumidifying function through the regeneration process. In this case, the regeneration process utilizes a method in which regeneration air heated using a heater is passed through the dehumidifying rotor to remove moisture from the dehumidifying rotor and regenerate it.

[0005] Meanwhile, to save on regeneration time and energy consumption during the regeneration process, a microwave-based dehumidification system can be introduced that removes moisture absorbed by the desiccant through microwave heating. Previously, a system was provided in which a microwave module, which irradiates microwaves, was directly placed on a dehumidification rotor.

[0006] In a conventional microwave dehumidification system, multiple microwave modules are coupled to a dehumidifying rotor, which is a cylindrical reactor, and the regeneration module that supplies regeneration air to the dehumidifying rotor rotates stepwise. In this state, the regeneration area of ​​the dehumidifying rotor is 1 / 8, but since the dehumidifying rotor is fixed, eight microwave modules are required. In addition, since the regeneration module rotates, there is a problem in that the waste heat recovery piping is configured as a double piping. In addition, the double piping configuration is complicated, which causes manufacturing costs and an increase in the regeneration differential pressure.

[0007]

[0008] The present invention aims to solve the above-mentioned problems and other problems.

[0009] Another object of the present invention is to provide a dehumidification system that enables cost reduction and energy reduction by sequentially heating and regenerating a plurality of dehumidifiers coupled to a rotating reactor using a regeneration chamber equipped with a microwave module.

[0010] A dehumidification system using microwaves according to one embodiment of the present invention comprises: a reactor body having a receiving space formed therein; a plurality of partition walls formed radially with respect to a central axis to divide the receiving space into a plurality of divided regions; and a plurality of dehumidifiers arranged in each of the plurality of divided regions and absorbing moisture of air passing into the receiving space; a regeneration module arranged to correspond to at least one of the plurality of divided regions and performing regeneration on the dehumidifier located in the at least one divided region among the plurality of dehumidifiers; and an exhaust module enabling external exhaust of air passing through the dehumidifier forming the reactor; wherein the regeneration module comprises a regeneration chamber arranged to correspond to at least one of the plurality of divided regions and supplying a portion of dehumidified air passing through the reactor, and a plurality of microwave modules arranged on the regeneration chamber, wherein the plurality of microwave modules are arranged along an outer surface of the regeneration chamber, and the plurality of microwave modules can irradiate microwaves onto the dehumidifier in the at least one divided region.

[0011] The effects of the dehumidification system using microwaves according to the present invention are described as follows.

[0012] According to at least one embodiment of the present invention, by arranging microwave modules only on regeneration modules arranged on one side of a rotating reactor, the number of microwave modules installed in each of the plurality of desiccant regions forming a conventional dehumidifying rotor is significantly reduced, thereby enabling a reduction in the cost of the dehumidifier. For example, the number of microwave modules can be reduced to 1 / 5 compared to the conventional one, and at the same time, the number of microwave module power supplies can be reduced to 1 / 5 compared to the conventional one, thereby enabling simplification of piping and reduction of the volume of the lower side of the cylindrical reactor.

[0013] According to at least one of the embodiments of the present invention, the energy efficiency of the dehumidifier can be improved by increasing the number of microwave modules used in regeneration of one of a plurality of dehumidifiers coupled to the reactor by at least 50%.

[0014] In addition, it is possible to increase the dispersibility of microwave energy transmitted to the desiccant and reduce the amount of adsorbent used per unit MW power [kg / kW].

[0015] Further scope of the applicability of the present invention will become apparent from the detailed description below.

[0040] Referring to FIGS. 1 to 13, a dehumidification system (1) according to one embodiment of the present invention may include a reactor (10), a regeneration module (20) that enables regeneration of a dehumidifier placed in the reactor (10), an exhaust module (30) that enables heating for regeneration of a portion of air that has passed through the dehumidifier forming the reactor (10) and external discharge of the regenerated dehumidifier, a housing (40) that accommodates the reactor (10) therein, an intake pipe (70) placed on one side of the housing (40), an exhaust pipe (80) placed on the other side of the housing (40), and a heating device (100) connected to the regeneration module (20) and the exhaust module (30).

[0041] Below, the structure of the dehumidification system (1) based on the reactor (10) performing the dehumidification function is specifically described.

[0042] First, referring to FIGS. 1 to 3, a dehumidification system (1) according to one embodiment of the present invention can remove moisture from air injected into a housing (40) and discharge it to the outside. The dehumidification system (1) can periodically remove moisture from air injected into the inside by repeating dehumidification and regeneration processes.

[0043] A dehumidification system (1) can create a process environment by providing dry air from which moisture has been removed to a process space. The process may include painting work, battery manufacturing, semiconductor and LCD manufacturing, and petrochemical processes that require a dry environment.

[0044] The intake duct (70) can be connected to the inside of the housing (40) from the intake duct (50). The intake duct (50) can suck in outside air, for example, air from a process plant or outside air, into the dehumidification system (1).

[0045] An intake fan (not shown) may be positioned in the intake duct (50) or intake pipe (70), and the intake duct (50) and intake pipe (70) may form a path that receives air from the intake fan (not shown) and allows it to flow into the interior of the housing (40).

[0046] The housing (40) may include an intake port (410) and an exhaust port (420). The intake port (410) is connected to an intake pipe (70) to receive air from the outside, and the exhaust port (420) may deliver air to the outside through an exhaust pipe (80). A reactor (10) may be provided inside the housing (40) to form a dehumidifying space inside the housing (40).

[0047] The dehumidification system (1) removes moisture from air drawn in through an intake port (410) and passes it through a reactor (10), and provides the dehumidified air to the outside, for example, a process space, through an exhaust port (420), thereby controlling the temperature or humidity of the process environment.

[0048] The reactor (10) is located inside the housing (40) and can absorb moisture from the air introduced into the housing (40). The reactor (10) that has absorbed moisture from the air can be dehumidified by the regeneration module (20) described below and maintained in a dry state again. The reactor (10) can remove moisture from the air introduced into the housing (40) by repeating the absorption and dehumidification process.

[0049] A reactor (10) according to one embodiment of the present invention can rotate around a central axis. The reactor (10) may be referred to as a dehumidifying rotor. The reactor (10) may have a cylindrical or polygonal three-dimensional shape. The reactor (10) in the present invention can be described as having a cylindrical shape.

[0050] The reactor (10) can have air introduced into some areas, for example, the upper surface, and air can pass through and be discharged into other areas, for example, the lower surface. Here, a plate-shaped member perforated on the lower surface of the reactor (10) can be used.

[0051] The reactor (10) can control the humidity of the air by including a desiccant (130), but is not limited thereto, and inside the reactor (10), a temperature control module (not shown), a chemical reaction module (not shown), or a cleaning module (not shown) can be provided to control the properties or components of the fluid by passing the fluid through the module.

[0052] The reactor (10) is arranged inside the housing (40) and can absorb moisture when the intake air passes through it. The reactor (10) can be fixedly arranged inside the housing (40). The reactor (10) can be provided with a reactor body (110) formed in a cylindrical shape with a receiving space formed inside it and a plurality of partition walls (120) formed radially based on a central axis to divide the receiving space into a plurality of divided regions.

[0053] The plurality of partition areas can be formed to have a fan-shaped cross-section when viewed perpendicular to the path of movement of the fluid passing through the housing (40).

[0054] The reactor (10) may be filled with a desiccant (130) that absorbs moisture in the air passing through the receiving space. The desiccant (130) may be placed in each of the plurality of divided areas described above.

[0055] Here, the desiccant (130) may include silica gel or zeolite. However, the type of the desiccant (130) is not limited thereto, and any material that absorbs moisture may be used.

[0056] Additionally, the desiccant may further include additives including carbon (C), silicon carbide (SiC), and metal particles that absorb microwaves, and may be stirred with silica gel or zeolite to form beads.

[0057] The regeneration module (20) can regenerate the reactor (10) by dehumidifying moisture absorbed into the reactor (10). For example, depending on the rotation of the reactor (10), the regeneration module (20) can be sequentially placed on one of the plurality of dehumidifiers so as to correspond to at least some of the plurality of divided regions formed in the reactor (10).

[0058] In accordance with the rotational drive of the reactor (10) according to the regeneration cycle set in the control module (101), the regeneration module (20) and the discharge module (30) can sequentially move through a plurality of divided areas and seal the upper and lower surfaces of each of the plurality of divided areas.

[0059] The desiccant of the reactor (10) can be regenerated by passing humid air or regeneration air through the desiccant located inside the sealed partition area. That is, when the reactor (10) is rotated, the regeneration module (20) and the discharge module (30) respectively positioned at the upper and lower portions of the reactor (10) can move in the upper and lower direction with respect to the reactor (10) and be separated from the reactor (10).

[0060] Meanwhile, when the rotation of the reactor (10) has stopped, the regeneration module (20) and the discharge module (30) can move relative to the reactor (10) and be in close contact with the reactor (10).

[0061] Referring to FIGS. 3 to 11, the regeneration module (20) may include a supply air pipe (21) for supplying regeneration air to the reactor (10), a regeneration chamber (210) for sequentially supplying regeneration air to a plurality of dehumidifiers (130) respectively arranged in a plurality of divided regions formed in the reactor (10), a plurality of microwave modules (220) arranged on the regeneration chamber (210), a perforated plate (230) arranged on the inner side of the regeneration chamber (210), and a sealing member (240) coupled to the lower end of the regeneration chamber (210).

[0062] The regeneration chamber (210) may have an internal space capable of entirely covering the desiccant (130) disposed in a plurality of partitioned areas formed in the reactor (10). For example, the regeneration chamber (210) may be configured to form a predetermined closed space on the upper portion of the desiccant (130) contained in the receiving space of the reactor body (110).

[0063] The regeneration chamber (210) may include a chamber upper frame (211) on which a plurality of microwave modules (220) are arranged along its outer surface. The chamber upper frame (211) may have a predetermined space formed therein. The chamber upper frame (211) may have a space that gradually expands from the top to the bottom.

[0064] The chamber upper frame (211) may have a shape in which the horizontal cross-sectional area gradually increases as it goes downward. For example, a plurality of outer surfaces forming the chamber upper frame (211) in the upper-to-lower direction may be arranged to be inclined in the lower outer direction.

[0065] The chamber upper frame (211) may have a polyhedral shape. Specifically, for example, it may have a shape having multiple faces with the lower part being open. For example, the chamber upper frame (211) may have a shape in which multiple faces are continuously connected along the circumferential direction.

[0066] Specifically, the chamber upper frame (211) may include a first side frame (2111) disposed on one side of the chamber upper frame (211), a second side frame (2112) disposed opposite the first side frame (2111), a rear frame (2113) disposed on the rear of the upper frame (211) to connect the first side frame (2111) and the second side frame (2112), a front frame (2114) disposed on the front of the upper frame (211) to connect the first side frame (2111) and the second side frame (2112), and an upper frame (2115) disposed on the upper side of the upper frame (211) to connect the first side frame (2111), the second side frame (2112), and the rear frame (2113).

[0067] The first side frame (2111) and the second side frame (2112) may each have a trapezoidal shape. The rear frame (2113) may have an upper side that contacts the upper frame (2115), a pair of side sides that contact the first side frame (2111) and the second side frame (2112), and a lower side that has a curved shape connecting the lower ends of the pair of side sides.

[0068] The front frame (2114) may have a pair of side edges that contact the front end of the first side frame (2111) and the front end of the second side frame (2112), respectively, and a lower edge having a straight shape connecting the lower ends of the pair of side edges. For example, the front frame (2114) may have an isosceles triangle shape. For example, the upper frame (2115) may also have an isosceles triangle shape.

[0069] The regeneration chamber (210) may include a chamber central frame (212) coupled to the lower end of the chamber upper frame (211). The chamber central frame (212) may have a shape that connects central frame members extending downward from the lower ends of the first side frame (2111), the second side frame (2112), the rear frame (2113), and the front frame (2114), respectively.

[0070] Among the above central frame members, the central frame members extending from the lower ends of the first side frame (2111), the second side frame (2112), and the front frame (2114) may have a flat plate shape. Meanwhile, the central frame member extending from the lower end of the rear frame (2113) may have a curved shape.

[0071] The regeneration chamber (210) may include a chamber bottom frame (213) coupled to the lower portion of the chamber center frame (212). The chamber bottom frame (213) may include a sealing groove that enables coupling of a sealing member (240).

[0072] The regeneration chamber (210) may include a plurality of microwave mounting holes (214) coupled to the chamber upper frame (211). The plurality of microwave mounting holes (214) may be arranged in plurality on each of the first side frame (2111), the second side frame (2112), and the rear frame (2113).

[0073] For example, a plurality of microwave mounting holes (214) may be configured such that a pair of microwave modules (220) are each disposed on a first side frame (2111), a second side frame (2112), and a rear frame (2113). The pair of microwave modules (220) may be formed to have different arrangement angles on the first side frame (2111), the second side frame (2112), and the rear frame (2113).

[0074] For example, in the first side frame (2111), one of the pair of microwave modules (220) may be arranged in a horizontal direction, while the other microwave module may be arranged in a vertical direction. The pair of microwave modules (220) may be arranged in mutually orthogonal directions.

[0075] The orthogonal arrangement of a pair of microwave modules (220) can enhance the isolation between the microwave mounting holes (214). "Decoupling" can occur, where microwaves input from the left microwave mounting hole among the microwave mounting holes (214) can exit from the right microwave mounting hole. The present invention can minimize the above-described decoupling phenomenon through the orthogonal arrangement of the microwave modules (220).

[0076] A plurality of microwave modules (220) may be arranged according to a certain rule on a number of surfaces forming the chamber upper frame (211). For example, assuming a sequential arrangement along the first side frame (2111), the second side frame (2112), and the rear frame (2113) (i.e., an arrangement along the counterclockwise direction in FIG. 8), it may be possible to arrange a pair of microwave modules regularly so that they have a horizontal direction and a vertical direction in sequence on each frame (2111, 2112, 2113).

[0077] That is, on the first side frame (2111), a first microwave mounting hole (2141) having a horizontal direction and a second microwave mounting hole (2142) having a vertical direction may be arranged along one direction, and on the second side frame (2112), a first microwave mounting hole (2141) having a horizontal direction and a second microwave mounting hole (2142) having a vertical direction may be arranged along the same arrangement direction as on the first side frame (2111).

[0078] Meanwhile, referring to FIG. 12, the microwave mounting holes (2141, 2142) are shown in a state where they protrude a predetermined distance from the surface of the chamber upper frame (211).

[0079] The regeneration chamber (210) may include a regeneration air supply port (215) coupled to an upper frame (2115). The regeneration air supply port (215) may be coupled to an air supply duct (21).

[0080] A plurality of microwave modules (220) may each be equipped with at least one irradiation unit (221) for irradiating microwaves. The side of the regeneration chamber (210) may be configured with a mica plate to allow microwaves to pass through and heat the desiccant (130).

[0081] Here, the irradiation unit (221) may be a magnetron, but is not limited thereto, and any means capable of irradiating microwaves may be used. In addition, the mica plate may be changed to a plate made of any material that allows microwaves to pass through.

[0082] The microwave module (220) may employ a method of irradiating microwaves to the regeneration area through a waveguide (222). The waveguide (222) may form a passage through which microwaves irradiated from the irradiation unit (221) pass.

[0083] At this time, the microwave module (220) can evenly divide the passage through which microwaves pass through a space formed by the first side frame (2111), the second side frame (2112), the rear frame (2113), and the front frame (2114) so ​​that the microwaves can be irradiated relatively evenly to the reproduction area.

[0084] That is, a plurality of microwave modules (220) can be configured to uniformly irradiate microwaves by being distributed across the first side frame (2111), the second side frame (2112), and the rear frame (2113).

[0085] Referring to Fig. 10, the perforated plate (230) disposed on the inner side of the regeneration chamber (210) may be disposed on the lower side of the upper frame (2115). The perforated plate (230) may be disposed in an area surrounded by the first side frame (2111), the second side frame (2112), and the rear frame (2113).

[0086] The perforated plate (230) may have a plurality of perforated through holes (232) formed on a triangular or isosceles triangular frame. The perforated plate (230) may have an air passage function and a microwave shielding function. That is, the perforated plate may be installed to prevent microwaves from leaking into the upper pipe.

[0087] The perforated plate may be made of metal. If the diameter of the perforated plate is less than approximately 1 / 50th of the wavelength, electromagnetic waves may not pass through. For example, the black mesh installed in a household microwave oven can function as a perforated plate.

[0088] Meanwhile, referring again to FIGS. 2 to 5, the exhaust module (30) may include a first lower chamber (310) arranged to face a regeneration chamber (210) that supplies regeneration air based on the reactor (10) and a second lower chamber (320) that receives external air that has passed through a regenerated desiccant.

[0089] The first lower chamber (310) allows air passing through the dehumidifier (130A, 130) undergoing regeneration to be discharged to the outside from inside the housing (40). The second lower chamber (320) allows air passing through the dehumidifier (130B, 130) that has completed regeneration to flow to the heating device (100) through the second discharge pipe (32).

[0090] The first lower chamber (310) may be structured to face the regeneration chamber (210) in a vertical direction with respect to the reactor (10). The first lower chamber (310) may be connected to an external discharge pipe (90) through a first discharge pipe (31).

[0091] The external exhaust pipe (90) can exhaust the received air to the outside of the housing (40) of the dehumidification system (1). The external exhaust pipe (90) can include an exhaust duct (60) communicating with the first lower chamber (310) and an exhaust fan (not shown) that induces exhaust of air.

[0092] The external exhaust pipe (90) is connected to the outside of the dehumidification system (1) and can discharge air sucked from the first lower chamber (310) to the outside, for example, to the outside of the dehumidification system (1) rather than the process space. The external exhaust pipe (90) can regenerate the dehumidifier through the regeneration chamber (210) and the first lower chamber (310) and discharge humid air to the outside.

[0093] A heating device (100) according to one embodiment of the present invention can transfer air sucked into a second lower chamber (320) to a regeneration chamber (210). The second lower chamber (320) can be communicated with the heating device (100) through a second discharge pipe (32).

[0094] For example, the heating device (100) can circulate the supplied air and deliver it back to the regeneration chamber (210) through the air supply pipe (21). For example, the heating device (100) can heat a portion of the supplied air and deliver it to the regeneration chamber (210).

[0095] As described above, the heating device (100) can receive air from the second lower chamber (320), heat it, and provide it to the regeneration chamber (210). Through this, the dehumidification system according to the present invention can dehumidify the reactor (10) and recover some of the air discharged to the outside and recirculate it to the regeneration chamber (210).

[0096] Meanwhile, the air introduced into the housing (40) and dehumidified by the reactor (10) may be at a high temperature. The heating device (100) may recover some of the dehumidified air at a high temperature and recirculate it into the regeneration chamber (210).

[0097] For example, the dehumidifying agent dehumidified by the air injected by the regeneration chamber (210) may be at a high temperature. Meanwhile, the air passed through the reactor (10) and delivered to the second lower chamber (320) may be air that cools the dehumidifying agent immediately after regeneration.

[0098] That is, the air delivered to the second lower chamber (320) may have a relatively high temperature compared to the temperature of the air introduced into the housing (40), but may have a low temperature and low humidity compared to the temperature of the air supplied through the heating device (100). The heating device (100) can reheat the humid air delivered from the second lower chamber (320) to increase its temperature and deliver it back to the regeneration chamber (210).

[0099] Since the air passing through the reactor (10) may have a temperature higher than room temperature, the heating device (100) can repeatedly heat and circulate the air with a relatively lower temperature, thereby improving energy efficiency in the regeneration process of the dehumidification system (1).

[0100] Referring to Fig. 11, the sealing member (240) may be coupled to a sealing groove (not shown) formed at the bottom of the chamber lower frame (213). The sealing groove may be a groove-shaped groove formed concavely along the bottom of the chamber lower frame (213). For example, the sealing member (240) may be press-fitted into the sealing groove.

[0101] The above sealing member (240) can increase the sealing force between the regeneration chamber (210) and the partition area where the desiccant (130) is placed.

[0102] The sealing member (240) may include a ring-type outer member (241) forming the overall outer frame, an intermediate member (242) formed to extend from the inner surface of the outer member (241), an inner member (243) formed to extend from the inner surface of the intermediate member (242), and a sealing member (244) formed to protrude between the outer member (241) and the intermediate member (242).

[0103] The intermediate member (242) can extend in an inclined direction between the stepped outer member (241) and the inner member (243). That is, the intermediate member (242) can be inclined in a direction opposite to the protruding direction of the sealing member (244). The intermediate member (242) can have a structure that connects the outer member (241) and the inner member (243).

[0104] The sealing member (240) can use two types of gaskets. The sealing member (240) can use an air blocking gasket (high-temperature silicone material) and an electromagnetic wave blocking gasket (conductive helical type) at the same time.

[0105] Since electromagnetic shielding gaskets are not designed for high temperatures, they can be installed outside. Since air-blocking gaskets do not block electromagnetic waves, and electromagnetic shielding gaskets do not block air, it may be advisable to use both types of gaskets simultaneously.

[0113] The sensor assembly (3) can generate a second signal (S2) including information about temperature and flow rate and transmit it to the control module (101). Based on the second signal (S2), the control module (101) can obtain at least one piece of information about temperature and flow rate from the regeneration system including the housing (40) and the reactor (10).

[0114] The control module (101) can generate a third signal (S3) based on the input signals (S1, S2). The third signal (S3) can include information regarding the operation of the intake duct (50). For example, the third signal (S3) can include information regarding at least one of the opening / closing amount and the operating cycle of the intake valve disposed in the intake duct (50).

[0115] The control module (101) can transmit a third signal (S3) to the intake duct (50). The intake duct (50) can control the operation of the intake valve according to the third signal (S3).

[0116] The control module (101) can generate a fourth signal (S4) based on the input signals (S1, S2). The fourth signal (S4) can include information regarding the operation of the exhaust duct (60).

[0118] The control module (101) can generate a fifth signal (S5) based on the input signals (S1, S2). The fifth signal (S5) can include information regarding the operation of the reactor (10).

[0119] The control module (101) can transmit a fifth signal (S5) to the reactor (10). The rotation cycle of the reactor (10) can be controlled according to the fifth signal (S5).

[0120] The control module (101) can generate a sixth signal (S6) based on the input signals (S1, S2).

For example, the sixth signal (S6) can include information regarding the operation of the regeneration module (20) for any one of the plurality of dehumidifiers placed in the reactor (10) that requires regeneration.

[0122] The control module (101) can generate a seventh signal (S7) based on the input signals (S1, S2). The seventh signal (S7) can include information regarding the operation of the discharge module (30). For example, the seventh signal (S7) can include information regarding the operation of the discharge module (30) for any one of the plurality of dehumidifiers arranged in the reactor (10) that requires regeneration.

[0123] The control module (101) can transmit a seventh signal (S7) to the discharge module (30). The discharge module (30) can control the elevation and descent of the desiccant placed in the reactor (10) according to the seventh signal (S7).

[0124] The control module (101) can generate an eighth signal (S8) based on the input signals (S1, S2). The eighth signal (S8) can include information regarding the operation of the heating device (100). For example, the eighth signal (S8) can include information regarding the operation of the heating device (100), which has a function of reheating low-humidity air received from the second lower chamber (320) to increase its temperature and transmitting the regeneration chamber (210).

[0125] The control module (101) can transmit an eighth signal (S8) to the heating device (100). The heating device (100) can control the temperature of air supplied to the regeneration chamber (210) according to the eighth signal (S8).

[0126] The control module (101) can control the operation of at least some of the reactor (10), the regeneration module (20), the exhaust module (30), the intake duct (50), the exhaust duct (60), and the heating device (100). The control module (101) according to one embodiment of the present invention includes a driving device (not shown) to rotate the reactor (10) at a predetermined angle with respect to the central axis of the reactor (10) so that the regeneration chamber (210) is sequentially opposed to each of the plurality of divided regions.

[0127] Additionally, the control module (101) can rotate the reactor (10) at a predetermined angle with respect to the central axis of the reactor (10) so that the first lower chamber (310) and the second lower chamber (320) are sequentially opposed to each of the plurality of divided regions of the reactor (10).

[0128] The control module (101) controls the periodic rotation of the reactor (10), and can control the regeneration chamber (210), the first lower chamber (310), and the second lower chamber (320) to be moved up and down to bring them into close contact in order to dehumidify and regenerate some of the desiccant (130) arranged in the plurality of divided areas formed in the reactor (10). At this time, the irradiation unit (221) can be operated to transmit microwaves to the waveguide (222) in some area where the regeneration chamber (210) is located.

[0129] In other words, the control module (101) can operate the irradiation unit (221) to irradiate microwaves only to a portion of the area sealed with the regeneration chamber (210). At this time, the desiccant (330) in the portion of the area irradiated with microwaves is heated, and moisture contained in the desiccant (330) can be dehumidified and changed into a form of water vapor. The water vapor can be discharged to the outside through the regeneration chamber (210) and the first lower chamber (310). Through this, the desiccant can be regenerated to enable dehumidification.

[0130] The regeneration chamber (210) can be maintained in a fixed state, and the control module (101) can enable the reactor (10) to rotate in steps about the central axis of the reactor (10). The step rotation can be defined as a stepwise rotation in which one rotation of the reactor (10) is divided into predetermined angles. For example, if one step rotation is set to rotate by 18 degrees, 20 step rotations can mean one rotation.

[0131] The microwave module (220) may be operated for a preset period of time, which is a regeneration time. When the operation of the microwave module (220) is stopped, the upper regeneration chamber (210) may be raised while the lower chambers (310, 320) may be lowered. Thereafter, the control module (101) may enable a one-step rotation of the reactor (10).

[0132] Next, the control module (101) can enable the lower chamber (310, 320) to ascend simultaneously with the lowering of the regeneration chamber (210). Next, the microwave module (220) can be operated for a preset period of time, which is the regeneration time.

[0133] As described above, a cycle including the operation of the microwave module (220), the rising of the regeneration chamber (210) and the lowering of the lower chamber (310, 320), the step rotation of the reactor (10), and the lowering of the regeneration chamber (210) and the rising of the lower chamber (310, 320) can be repeated.

[0134] The control module (101) can control to irradiate microwaves to a portion of the divided area where the regeneration chamber (210) is located for a shorter period of time than the rotation cycle of the reactor (10). In other words, the microwave irradiation time can be made shorter than the time for which the regeneration chamber (210) is located in the portion of the divided area. The regeneration chamber (210) can continue to operate even after the microwave irradiation is finished, and can cool the desiccant (130) heated by the microwave irradiation.

[0135] A dehumidification system (1) according to one embodiment of the present invention can cool a dehumidifier (130) under the control of a control module (101). In addition, the dehumidification system (1) enables dehumidification of the dehumidifier (130) when the regeneration chamber (210) moves, and can be used in some temperature-sensitive processes.

[0136] Meanwhile, the control module (101) may be a module for control, such as a circuit board equipped with a processor, a programmable logic controller (PLC), or a recording medium in which a program is stored. The control module (101) is not limited thereto, and may also be configured with at least one or more switch-type modules, such as a mechanical contact switch, limit switch, or timer for simple contact control.

[0137] In the present invention, the reactor (10) is controlled by a control module (101) and can rotate around the central axis of the reactor (10). Meanwhile, the regeneration chamber (210), the first lower chamber (310), and the second lower chamber (320) of the regeneration module (20) can maintain a fixed position. The regeneration chamber (210) moves up and down with respect to the reactor (10), and the reactor (10) having a cylindrical shape rotates on its own.

[0138] Due to the above features, independent piping can be used for the recovery of waste heat generated in the reactor (10) instead of the existing dual piping. This can have the advantage of reducing the differential pressure of the regenerated air.

[0139] That is, in order to regenerate and inflow / outflow of air through the dehumidification system, the regeneration chamber (210), the first lower chamber (310), and the second lower chamber (320) of the regeneration module (20) are fixed, while the rotation of the reactor having the dehumidifier is enabled, thereby improving the efficiency of the installation space.

[0140] Any or all of the embodiments of the present invention described above are not mutually exclusive or distinct. Any or all of the embodiments of the present invention described above may have their respective components or functions combined or used together.

[0141] It will be apparent to those skilled in the art that the present invention may be embodied in other specific forms without departing from the spirit and essential characteristics thereof. The above detailed description should not be construed in any way as limiting but rather as illustrative. The scope of the present invention should be determined by a reasonable interpretation of the appended claims, and all modifications within the scope of equivalents of the present invention are intended to be included within the scope of the present invention.
