[0028]

[0029] Referring to the attached drawings below, a device having a harmful gas purification and recovery function according to the present invention will be described in detail.

[0030]

[0031] [Example 1-1] The present invention relates to a device having a harmful gas purification and recovery function, comprising: a first suction damper (210) including an inlet (13) through which gas is introduced; a first discharge terminal (11) through which the introduced gas is discharged; a second discharge terminal (12); a switching unit (30) for changing the direction of flow of the introduced gas depending on the position; a first chamber (110) including a first inlet and a first discharge terminal, wherein the first inlet is connected to the first discharge terminal of the first suction damper (210), and a harmful gas filter is built in; a second chamber (120) including a second inlet and a second discharge terminal, wherein the second inlet is connected to the second discharge terminal of the first suction damper (210), and a first inlet terminal (21) connected to the first discharge terminal; A second inlet (22) connected to the second-first outlet, an outlet (23) through which the introduced gas is discharged, a second adsorption damper (220) including a switching unit for changing the direction of travel of the introduced gas depending on the position, a control unit for controlling the first adsorption damper (210) and the second adsorption damper (220), and for causing at least one of the first chamber (110) and the second chamber (120) to operate in an adsorption mode of a hazardous substance contained in a gas, in a desorption mode of a hazardous substance, or in a raw material regeneration mode for regenerating the hazardous substance as a raw material.

[0032] [Example 1-2] The present invention relates to a device having a function of purifying and recovering harmful gases, and in Example 1-1, includes an exhaust fan (400) that is connected to the discharge end of the second adsorption damper (220) and operates to generate a flow of the gas when either of the first chamber (110) and the second chamber (120) operates to adsorb pollutants contained in the gas, and is controlled by the control unit.

[0033] [Example 1-3] The present invention relates to a device having a harmful gas purification and recovery function. In Example 1-2, the control unit controls the first adsorption damper (210) and the second adsorption damper (220) to allow gas to flow into one of the first chamber (110) and the second chamber (120), connects to the exhaust fan (400), and operates the exhaust fan (400) to allow one of the first chamber (110) and the second chamber (120) to operate in an adsorption mode.

[0034] [Example 1-4] The present invention relates to a device having a harmful gas purification and recovery function, and in Example 1-1, includes a pretreatment filter unit (101) connected to the inlet end of the first adsorption damper (210) to filter foreign substances contained in the inlet gas.

[0035] The present invention relates to a device having a harmful gas purification and recovery function that adsorbs harmful substances contained in gas and, in addition, regenerates or decomposes the adsorbed harmful substances.

[0036] A device having a harmful gas purification and recovery function according to the present invention includes a first adsorption damper (210), a first chamber (110), a second chamber (120), a second adsorption damper (220), and a control unit.

[0037] The first chamber (110) and the second chamber (120) are arranged in parallel with each other, the first suction damper (210) is arranged at the front end of each of the first chamber (110) and the second chamber (120), and the second suction damper (220) is arranged at the rear end of each of the first chamber (110) and the second chamber (120).

[0038] The first adsorption damper (210) includes an inlet end (13), a first discharge end (11), a second discharge end (12), and a switching part (30).

[0039] Each of the inlet port (13), the first discharge port (11), and the second discharge port (12) is formed in a type of housing, and the gas flowing into the inlet port (13) has a path determined by the switching unit (30) and can be discharged to the first discharge port (11), the second discharge port (12), or each of the first discharge port (11) and the second discharge port (12). The switching unit (30) rotates inside the housing to change the direction of gas flow, and a separate motor is directly or indirectly connected to the rotational axis of the switching unit (30) to control the rotation of the switching unit (30), thereby determining the direction of gas flow within the first adsorption damper (210).

[0040] The first chamber (110) includes a first-first inlet (111) and a first-first outlet (112), and the first-first inlet (111) is connected to the first outlet (11) of the first suction damper (210).

[0041] The second chamber (120) includes a second-1 inlet (121) and a second-1 outlet (122), and the second-1 inlet (121) is connected to the second outlet (12) of the first suction damper (210).

[0042] One of the first chamber (110) and the second chamber (120) can operate in an adsorption mode for harmful substances contained in the gas, and the other can operate in a desorption or regeneration mode for the harmful substances. A harmful gas filter is built into each of the first chamber (110) and the second chamber (120). The harmful gas filter may be an ACF (Activated Carbon Fiber) filter. The ACF filter is made of much smaller and finer fibers than general activated carbon, so it has a very large surface area and adsorbs harmful substances contained in the gas passing through the ACF filter. However, the present invention is not limited to the ACF filter as the harmful gas filter, and various adsorption materials such as zeolite can be used in addition to ACF.

[0043] The second adsorption damper (220) includes a first inlet port (21), a second inlet port (22), a discharge port (23), and a switching unit (30) similar to the first adsorption damper (210). The first inlet port (21), the second inlet port (22), and the discharge port (23) are formed in one housing, and the switching unit (30) rotates inside the housing to determine the direction of gas flow. Here, determining the direction of gas flow means determining from which inlet port the gas discharged through the discharge port (23) is supplied. A motor may be directly or indirectly connected to the rotational shaft of the switching unit (30).

[0044] The control unit controls the first adsorption damper (210) and the second adsorption damper (220). More specifically, the control unit controls the motors connected to the switching units (30) of the first adsorption damper (210) and the second adsorption damper (220), respectively, to determine the direction of gas movement determined by the first adsorption damper (210) and the second adsorption damper (220). The control unit may be an electronic device that transmits a control signal to the motors connected to each of the first adsorption damper (210) and the second adsorption damper (220) and receives an operation feedback signal of each motor. For example, the control unit may be a PC, tablet, or smartphone installed on site, and may be interconnected with each motor by wire or wirelessly to transmit and receive signals. When the control unit is interconnected with each motor wirelessly, the wireless communication method may be a mobile communication network, wireless Internet, short-range wireless communication, etc.

[0045] An exhaust fan (400) may be connected to the rear end of the exhaust end (23) of the second adsorption damper (220). The exhaust fan (400) generates a gas flow in a chamber operating in adsorption mode among the first chamber (110) and the second chamber (120). The exhaust fan (400) may be controlled by the control unit described above.

[0046] Hereinafter, a description will be given of a control unit operating one of the first chamber (110) and the second chamber (120) in the adsorption mode. Assuming that the first chamber (110) among the first chamber (110) and the second chamber (120) operates in the adsorption mode, the control unit controls the first adsorption damper (210) to set a flow path so that gas can move from the inlet end (13) of the first adsorption damper (210) to the first discharge end (11). In addition, the control unit controls the second adsorption damper (220) to set a flow path so that gas can move from the first inlet end (21) of the second adsorption damper (220) to the discharge end (23). Thereafter, the control unit operates the exhaust fan (400) to allow gas to move to the first adsorption damper (210), the first chamber (110), the second adsorption damper (220), and the exhaust fan (400). In this process, as the gas passes through the first chamber (110), the harmful substance filter (40) built into the first chamber (110) adsorbs the harmful substances contained in the gas, so that the gas discharged to the outside atmosphere from the exhaust fan (400) contains harmful substances below the standard level.

[0047] When the second chamber (120) operates in adsorption mode, the control unit controls the first adsorption damper (210) and the second adsorption damper (220) to set a path for gas to pass through the second chamber (120).

[0048] The gas flowing into the first adsorption damper (210) may contain foreign substances, and if such foreign substances are adsorbed on the hazardous substance filter (40) accommodated inside the first chamber (110) or the second chamber (120), the performance of the hazardous substance filter (40) may deteriorate. To prevent this, a separate pre-treatment filter unit (101) is installed in front of the inlet end of the first adsorption damper (210) to filter foreign substances contained in the gas flowing into the first adsorption damper (210). The pre-treatment filter unit (101) may be a type of filter that removes foreign substances contained in the gas, such as a general HEPA filter.

[0049] In the present invention, the control unit can operate the first chamber (110) and the second chamber (120) simultaneously in the adsorption mode and the raw material regeneration mode, or in the adsorption mode and the desorption mode. However, the present invention is not limited thereto, and only one of the first chamber (110) and the second chamber (120) can be controlled to operate in any one of the adsorption mode, the desorption mode, and the raw material regeneration mode.

[0050]

In Example 2-1, the first chamber (110) includes a first-second inlet (113) connected to the steam supply unit (500) to receive steam, and a first-second outlet (114) connected to the condenser (600) to discharge harmful gases desorbed by steam generated inside.

[0053] [Example 2-3] The present invention relates to a device having a harmful gas purification and recovery function. In Example 2-2, the first chamber (110) includes a first-first valve (51) formed in the first-second inlet (113) and determining whether to supply steam from the steam supply unit (500).

[0055] [Example 2-5] The present invention relates to a device having a harmful gas purification and recovery function, and in Example 2-1, the second chamber (120) includes a second-second inlet (123) connected to the steam supply unit (500) to receive steam, and a second-second outlet (124) connected to the condenser (600) to discharge harmful gases desorbed by steam generated inside.

[0056] [Example 2-6] The present invention relates to a device having a harmful gas purification and recovery function, and in Example 2-5, the second chamber (120) includes a second-first valve (53) formed in the second-second inlet (123) and determining whether to supply steam from the steam supply unit (500).

[0057] [Example 2-7] The present invention relates to a device having a harmful gas purification and recovery function, and in Example 2-5, the second chamber (120) includes a second-second valve (54) formed in the second-second discharge port (124) and determining whether to discharge the harmful gas desorbed as steam.

[0058] [Example 2-8] The present invention relates to a device having a function of purifying and recovering harmful gases, and in Example 2-1, includes a pump (610) that is connected to the first chamber (110) and moves harmful gases desorbed by steam from inside the first chamber (110) to the condenser (600).

[0059] [Example 2-9] The present invention relates to a device having a harmful gas purification and recovery function, and in Example 2-1, includes a pump (610) that is connected to the second chamber (120) and moves the harmful gas desorbed as steam from inside the second chamber (120) to the condenser (600).

[0060] [Example 2-10] The present invention relates to a device having a harmful gas purification and recovery function, and in Example 2-1, includes a pump (610) that is connected to the first chamber (110) and the second chamber (120) and moves harmful gas desorbed by steam generated inside the first chamber (110) or the second chamber (120) to the condenser (600).

[0061] [Example 2-11] The present invention relates to a device having a harmful gas purification and recovery function, and in Example 2-1, includes a cooling fluid supply unit (620) that supplies cooling fluid to the condenser (600).

[0062] [Example 2-12] The present invention relates to a device having a harmful gas purification and recovery function, and in Example 2-1, includes a tank (630) that receives raw materials regenerated in the condenser (600).

[0063] [Example 2-13] The present invention relates to a device having a harmful gas purification and recovery function, and in Example 2-1, includes a level sensor installed in the tank (630) to sense the amount of raw material contained therein.

[0064] [Example 2-14] The present invention relates to a device having a harmful gas purification and recovery function. In Example 2-1, the control unit controls the first adsorption damper (210) and the second adsorption damper (220) to block the inlet and outlet of the chamber operating in the regeneration mode among the first chamber (110) and the second chamber (120), and operates the steam supply unit (500) to supply steam to the chamber operating in the regeneration mode.

[0065] [Example 2-15] The present invention relates to a device having a harmful gas purification and recovery function, and in Example 2-1, it includes a first branch flow path (631) having one end connected to the discharge end of raw materials generated from the condenser (600) and the other end connected to a tank in which raw materials are stored, and a second branch flow path (632) having one end connected to the discharge end of raw materials generated from the condenser (600) and the other end connected to the inlet end of the first adsorption damper (210).

[0066] The present invention (Examples 2-1 to 2-15) specifies a regeneration mode that uses hazardous substances contained in gas as raw materials.

[0067] While the hazardous substances contained in gases can vary in nature, the nature of the gas-generating process can sometimes lead to a majority of these substances being a single substance. In these cases, it's possible to recycle these hazardous substances and use them as raw materials.

[0068] Specifically, the hazardous substances adsorbed inside one of the first chamber (110) and the second chamber (120) are desorbed through steam injected into the chamber from the steam supply unit (500). When steam is injected into the chamber, the hazardous substances are contained in a gas having a high moisture content, and can be condensed to a certain extent through the high moisture content. Thereafter, the hazardous gas desorbed by the steam inside the chamber is transferred to the condenser (600). The condenser (600) cools the hazardous gas desorbed by the steam to regenerate the raw material.

[0069] The first chamber (110) includes a first-second inlet (113) connected to a steam supply unit (500) and a first-second outlet (114) connected to a condenser (600) through which harmful gases desorbed by steam generated inside are discharged. The condenser (600) is connected through a first condensate passage (601) connected to the first-second outlet (114) and through a second condensate passage (602) connected to the second-second outlet (124). The steam supply unit (500) and the first-second inlet (113) are connected through a first steam passage (501), and the steam supply unit (500) and the second-second inlet (123) are connected through a second steam passage (502).

[0070] The second chamber (120) includes a second-second inlet (123) connected to a steam supply unit (500) and a second-second outlet (124) connected to a condenser (600) through which harmful gases desorbed by steam generated inside are discharged.

[0071] A 1-1 valve (51) is formed at the 1-2 inlet (113) to determine whether to open or close the 1-2 inlet (113) and to determine whether to supply steam from the steam supply unit (500), and a 1-2 valve (52) is formed at the 1-2 outlet (114) to determine whether to discharge harmful gases desorbed by steam.

[0072] A 2-1 valve (53) is formed at the 2-2 inlet (123) to determine whether to open or close the 2-2 inlet (123) and to determine whether to supply steam from the steam supply unit (500), and a 2-2 valve (54) is formed at the 2-2 outlet (124) to determine whether to discharge harmful gases desorbed by steam.

[0073] Each of the above-described steam supply unit (500), condenser (600), 1-1 valve (51), 1-2 valve (52), 2-1 valve (53), and 2-2 valve (54) can be controlled by a control unit.

[0074] The pump (610) is connected to the first-second outlet (114) of the first chamber (110) and can discharge the harmful gas desorbed by the steam inside the first chamber (110) toward the condenser (600). In addition, the pump (610) is connected to the second-second outlet (124) of the second chamber (120) and can discharge the harmful gas desorbed by the steam inside the second chamber (120) toward the condenser (600). The pumps (610) connected to each of the first chamber (110) and the second chamber (120) may be different from each other or may be configured to operate as a single pump. However, since in the present invention, only one of the first chamber (110) and the second chamber (120) operates in the regeneration mode, it may be preferable for one pump (610) to be connected to both the first chamber (110) and the second chamber (120). The pump (610) may not continuously transfer the harmful gas desorbed by steam from the chamber to the condenser (600), but may transfer the harmful gas desorbed by a fixed amount of steam from the chamber to the condenser (600).

[0075] The condenser (600) serves to cool the desorbed harmful gases by the incoming steam. In this process, a cooling fluid is used, and the present invention may further include a cooling fluid supply unit (620) that supplies the cooling fluid to the condenser (600).

[0076] In addition, the present invention may further include a tank (630) that receives the regenerated raw material falling from the condenser (600), and a level sensor that senses the amount of the raw material received in the tank (630).

[0077] The chamber operating in the regeneration mode of the aforementioned raw material must block the passage used when operating in the adsorption mode to prevent the leakage of harmful gases desorbed by steam. Accordingly, the control unit can control the first adsorption damper (210) and the second adsorption damper (220) located at both ends of the chamber operating in the regeneration mode to close the inlet and outlet.

[0078] In the condenser (600), the desorbed harmful gas is cooled by the inflowing steam and regenerated as a raw material, but some of the gas may not be regenerated as a raw material. The gas that is not regenerated as a raw material may be supplied to the inflow end of the first adsorption damper (210) through the second branch flow path (632) connected to the inflow end of the first adsorption damper (210), and then introduced into the chamber operating in adsorption mode again. The first branch flow path (632) is a flow path that connects the condenser (600) to the tank (630). However, the first branch flow path (632) may not have a separate flow path, and there may also be an embodiment in which the tank (630) is simply located below the condenser (600).

[0079]

[0080] [Example 3-1] The present invention relates to a device having a harmful gas purification and recovery function, and in Example 1-1, the first chamber (110) includes a first-third inlet (115) and a first-third outlet (116), and the second chamber (120) includes a second-third inlet (125) and a second-third outlet (126), and includes a first desorption damper (230) including an inlet end, a first outlet end connected to the first-third inlet (115), and a second outlet end connected to the second-third inlet (125), a first inlet end connected to the first-third outlet (116), a second inlet end connected to the second-third outlet (126), and an outlet through which circulating gas introduced into the first inlet end or the second inlet end is discharged. A second detachment damper (240) includes a heater (710) whose one end is connected to the discharge end of the second detachment damper (240) and whose other end is connected to the inlet end of the first detachment damper (230).

[0081] [Embodiment 3-2] The present invention relates to a device having a harmful gas purification and recovery function. In Embodiment 3-1, when a predetermined time has elapsed after the regeneration mode operation, the control unit stops the operation of the steam supply unit (500) and the condenser (600), controls the first desorption damper (230) and the second desorption damper (240) so that the chamber that was in the regeneration mode operation among the first chamber (110) and the second chamber (120) is connected to the heater (710), and operates the heater (710) to operate in a drying mode to dry the inside of the chamber that was in the regeneration mode.

[0082] [Example 3-3] The present invention relates to a device having a harmful gas purification and recovery function, and in Example 3-2, includes a circulation fan (720) that is connected to the heater (710) and generates a flow of gas between the chamber in regeneration mode operation and the heater (710), and the control unit operates the circulation fan (720) in the drying mode.

[0083] [Example 3-4] The present invention relates to a device having a harmful gas purification and recovery function. In Example 3-2, the control unit performs the drying mode using the heater (710) for a predetermined period of time, and when the predetermined period of time has elapsed, the chamber in which the drying mode is performed and the heater (710) are disconnected from each other, and the switching unit included in each of the first desorption damper (230) and the second desorption damper (240) is opened to a certain degree so that the first chamber (110) and the second chamber (120) are connected to each other.

[0084] [Example 3-5] The present invention relates to a device having a harmful gas purification and recovery function, and in Example 3-4, it includes a first opening / closing valve (231) installed in front of the first desorption damper (230), and a second opening / closing valve (241) installed in the rear of the second desorption damper (240), and the control unit controls the first opening / closing valve (231) and the second opening / closing valve (241) when a predetermined time has elapsed after the drying mode is performed to disconnect the chamber operating in the drying mode from the heater (710).

[0085] [Example 3-6] The present invention relates to a device having a harmful gas purification and recovery function. In Example 3-4, when the temperature inside a chamber operating in a drying mode among the first chamber (110) and the second chamber (120) is cooled to a reference value or lower, the control unit controls the first desorption damper (230) and the second desorption damper (240) to separate the first chamber (110) and the second chamber (120) from each other.

[0086] [Embodiment 3-7] The present invention relates to a device having a harmful gas purification and recovery function, and in Embodiment 3-6, it includes a first chamber temperature sensor (61) installed inside the first chamber (110) to sense the temperature inside the first chamber (110) and transmit the sensed value to the control unit, and a second chamber temperature sensor (62) installed inside the second chamber (120) to sense the temperature inside the second chamber (120) and transmit the sensed value to the control unit, and the control unit determines whether to separate the first chamber (110) and the second chamber (120) based on the sensed values ​​of the first chamber temperature sensor (61) and the second chamber temperature sensor (62).

[0087] After operating in the regeneration mode described in the present invention (Examples 2-1 to 2-15), the interior of the chamber operating in the regeneration mode becomes a high-temperature and humid environment. Since the chamber cannot operate in the adsorption mode again in this environment, a process of drying and then cooling the interior of the chamber is required. This process is referred to as the drying mode and cooling mode.

[0088] The first chamber (110) includes a first-third inlet (115) and a first-third outlet (116), and the second chamber (120) includes a second-third inlet (125) and a second-third outlet (126).

[0089] The first detachment damper (230) and the second detachment damper (240) are respectively arranged at both ends of the first chamber (110) and the second chamber (120).

[0090] More specifically, the first desorption damper (230) includes an inlet end, a first discharge end, and a second discharge end, and the second desorption damper (240) includes a first inlet end, a second inlet end, and a discharge end.

[0091] The first discharge end of the first removal damper (230) is connected to the 1-3 inlet (115), and the second discharge end is connected to the 2-3 inlet (125).

[0092] The first inlet end of the second desorption damper (240) is connected to the first-third outlet (116), and the second inlet end is connected to the second-third outlet (126). A heater (710) is connected between the inlet end of the first desorption damper (230) and the outlet end of the second desorption damper (240). That is, depending on the case, the first chamber (110), the first desorption damper (230), the heater (710), and the second desorption damper (240) may form a circulation path, or the second chamber (120), the first desorption damper (230), the heater (710), and the second desorption damper (240) may form a circulation path.

[0093] The control unit controls the first desorption damper (230) and the second desorption damper (240) so that the chamber that was operated in the regeneration mode is included in the circulation path, and operates the heater (710) to dry the inside of the chamber that was operated in the regeneration mode. However, even if the heater (710) operates on the circulation path, the drying efficiency is bound to decrease if there is no air flow. Therefore, the present invention may include a circulation fan (720) installed on the circulation path, and when drying the inside of the chamber that was operated in the regeneration mode through the drying mode, the control unit may also operate the circulation fan (720) to increase the drying efficiency.

[0094] The control unit causes the drying mode to be performed for a predetermined period of time, and then, when the predetermined period of time has elapsed, the chamber and the heater (710) that operated the drying mode are disconnected from each other. The disconnection of the chamber and the heater (710) that operated the drying mode can be achieved by the operation of the first opening / closing valve (231) installed in front of the first desorption damper (230) (based on the gas flow direction) and the second opening / closing valve (241) installed in the rear of the second desorption damper (240). Of course, when operating in the drying mode, the first opening / closing valve (231) and the second opening / closing valve (241) can be opened. The first opening / closing valve (231) and the second opening / closing valve (241) can be controlled by the control unit. Thereafter, the control unit opens the switching units included in each of the first desorption damper (230) and the second desorption damper (240) only to a certain extent. In this case, the chamber that was operating in the dry mode and another chamber are connected to each other. In the case of the other chamber, since it is operating in the adsorption mode and gas is flowing, the gas inside the chamber that was operating in the dry mode flows into the chamber that is operating in the adsorption mode, and a certain amount of gas flows into the chamber that was operating in the dry mode from the exhaust end of the chamber that was operating in the adsorption mode. In other words, gas circulation occurs in the chamber that was operating in the dry mode, and during this process, not only does the temperature and humidity inside the chamber that was operating in the dry mode decrease, but there is also the effect of causing harmful substances that were not regenerated to flow into the chamber that is operating in the adsorption mode and be adsorbed. The above-described process is called the cooling mode.

[0095] The control unit opens the switching portions of the first desorption damper (230) and the second desorption damper (240) to a certain degree, and when the temperature inside the chamber that has recently been operating in the drying mode drops below a reference value while the first chamber (110) and the second chamber (120) are connected to each other, the control unit controls the first desorption damper (230) and the second desorption damper (240) to change the switching portions to a position prior to the time when they were controlled to be opened to a certain degree, thereby separating the first chamber (110) and the second chamber (120) from each other. The device having a harmful gas purification and recovery function according to the present invention includes a first chamber temperature sensor (61) installed inside the first chamber (110) and includes a second chamber temperature sensor (62) installed inside the second chamber (120). The sensing values ​​of each of the first chamber temperature sensor (61) and the second chamber temperature sensor (62) are transmitted to the control unit, and the control unit can determine the end point of the cooling mode based on the sensing values ​​of each of the first chamber temperature sensor (61) and the second chamber temperature sensor (62).

[0096] The above-described regeneration mode, drying mode, and cooling mode are collectively referred to as the raw material regeneration mode. Furthermore, the operating time of the raw material regeneration mode may be shorter than that of the adsorption mode in other chambers.

[0097]

[0098] [Example 4-1] The present invention relates to a device having a harmful gas purification and recovery function, and in Example 3-1, includes a catalyst (730) connected to at least one of both ends of the heater (710).

[0099] [Embodiment 4-2] The present invention relates to a device having a harmful gas purification and recovery function. In Embodiment 4-1, the control unit controls the first desorption damper (230) and the second desorption damper (240) to connect one of the first chamber (110) and the second chamber (120) to the catalyst (730) and the heater (710) to form a purification path, and operates the heater (710) to operate one of the first chamber (110) and the second chamber (120) in a desorption mode.

[0100] [Example 4-3] The present invention relates to a device having a harmful gas purification and recovery function, and in Example 4-2,

[0101] It includes a circulation fan (720) that is connected to the heater (710) and generates a flow of gas between the chamber that is in regeneration mode operation and the heater (710), and the control unit operates the circulation fan (720) when the detachment mode is in operation.

[0102] [Example 4-4] The present invention relates to a device having a harmful gas purification and recovery function. In Example 4-2, the control unit performs the desorption mode using the heater (710) for a predetermined period of time, and when the predetermined period of time has elapsed, the chamber in which the desorption mode is performed and the heater (710) are disconnected from each other, and the switching unit included in each of the first desorption damper (230) and the second desorption damper (240) is opened to a certain degree so that the first chamber (110) and the second chamber (120) are connected to each other.

[0103] [Example 4-5] The present invention relates to a device having a harmful gas purification and recovery function, and in Example 4-4, it includes a first opening / closing valve (231) installed in front of the first desorption damper (230), and a second opening / closing valve (241) installed in the rear of the second desorption damper (240), and the control unit controls the first opening / closing valve (231) and the second opening / closing valve (241) when a predetermined time has elapsed after the desorption mode is performed to disconnect the chamber in which the desorption mode is performed and the heater (710) from each other.

[0104] [Example 4-6] The present invention relates to a device having a harmful gas purification and recovery function. In Example 4-4, when the temperature inside a chamber operating in a desorption mode among the first chamber (110) and the second chamber (120) is cooled to a reference value or lower, the control unit controls the first desorption damper (230) and the second desorption damper (240) to separate the first chamber (110) and the second chamber (120) from each other.

[0105] [Embodiment 4-7] The present invention relates to a device having a harmful gas purification and recovery function, and in Embodiment 4-6, it includes a first chamber temperature sensor (61) installed inside the first chamber (110) to sense the temperature inside the first chamber (110) and transmit the sensed value to the control unit, and a second chamber temperature sensor (62) installed inside the second chamber (120) to sense the temperature inside the second chamber (120) and transmit the sensed value to the control unit, and the control unit determines whether to separate the first chamber (110) and the second chamber (120) based on the sensed values ​​of the first chamber temperature sensor (61) and the second chamber temperature sensor (62).

[0106] In the present invention described above (Examples 3-1 to 3-7), the drying mode and cooling mode performed after the regeneration mode operation in the raw material regeneration mode were described. The raw material regeneration mode described above is a process for regenerating hazardous substances contained in gas as raw materials. However, in some cases, it may be difficult to regenerate hazardous substances contained in gas. In such cases, if hazardous substances are adsorbed in a filter accommodated in either the first chamber (110) or the second chamber (120), the corresponding chamber can be operated in desorption mode to decompose the hazardous substances.

[0107] The decomposition of hazardous substances may further include a catalyst (730) in addition to the first desorption damper (230), the second desorption damper (240), and the heater (710), which are the necessary components in the drying mode described above. In fact, the desorption mode operates similarly to the drying mode. More specifically, in the desorption mode, the heater (710) is operated in a circulation path composed of the first desorption damper (230), the second desorption damper (240), the heater (710), the catalyst (730), and one of the first chamber (110) and the second chamber (120), and a circulation fan (720) is used to circulate high-temperature gas in the circulation path. The hazardous substances contained in the gas are decomposed in a high-temperature environment, and the catalyst (730) serves to promote this decomposition process. There may be various types of catalysts (730), and as some examples, the catalyst (730) may be at least one of a platinum catalyst and an iron catalyst.

[0108] Similar to the drying mode described above, it is necessary to lower the temperature inside the chamber operated in the desorption mode. When the desorption mode is performed and a predetermined time has elapsed, the control unit stops the heater (710) and the circulation fan (720), and operates the first opening / closing valve (231) and the second opening / closing valve (241) to separate the heater (710) and the catalyst (730) from the first chamber (110) or the second chamber (120). Thereafter, the switching units included in each of the first desorption damper (230) and the second desorption damper (240) are opened to a certain degree to connect the first chamber (110) and the second chamber (120) to each other, thereby cooling the inside of the chamber operated in the desorption mode. When the temperature inside the chamber drops below a reference value, the control unit operates the switching units included in each of the first desorption damper (230) and the second desorption damper (240) to their original positions. Afterwards, the chamber in which the desorption mode was performed waits to operate in the adsorption mode when switching the operation mode, and the chamber that was operating in the adsorption mode continues to operate in the adsorption mode.

[0109] As with the present invention described above, a first chamber temperature sensor (61) and a second chamber temperature sensor (62) are installed inside each of the first chamber (110) and the second chamber (120), so as to sense the temperature of each chamber and transmit the sensed value to the control unit.

[0110]

[0111] [Example 5-1] The present invention relates to a device having a harmful gas purification and recovery function. In Example 1-1, the control unit controls one of the first chamber (110) and the second chamber (120) to operate in an adsorption mode and the other in a desorption mode or a raw material regeneration mode, and after a predetermined time has elapsed, switches the operation modes of the two chambers to each other.

[0112] [Embodiment 5-2] The present invention relates to a device having a harmful gas purification and recovery function, and in Embodiment 5-1, a harmful substance sensor (70) is installed at the discharge end of the second adsorption damper (220) to sense the concentration of harmful substances in gas discharged from the second adsorption damper (220) and transmit the sensed value to the control unit, and the control unit switches the operation modes of each of the first chamber (110) and the second chamber (120) when the sensed value of the harmful substance sensor (70) reaches a reference value.

[0113] [Example 5-3] The present invention relates to a device having a harmful gas purification and recovery function, and in Example 5-1, it includes a timer for measuring time, and the control unit initializes the timer when one of the first chamber (110) and the second chamber (120) starts performing an adsorption operation of a harmful substance and the other starts performing a regeneration operation of a harmful substance, and when the time measured by the timer reaches a predetermined reference value, the operation mode of each chamber is switched to each other.

[0114] In the present invention, the operation modes of the first chamber (110) and the second chamber (120) can be switched with each other. Assuming that the first chamber (110) operates in the adsorption mode and the second chamber (120) operates in the desorption mode or the raw material regeneration mode for a first time, the function of the hazardous substance filter (40) accommodated inside the first chamber (110) deteriorates when the hazardous substance is sufficiently adsorbed. Therefore, it is necessary to desorb or regenerate the hazardous substance adsorbed in the hazardous substance filter (40) accommodated in the first chamber (110). Accordingly, the control unit can control each device to operate the first chamber (110) in the desorption mode or the raw material regeneration mode and the second chamber (120) in the adsorption mode after a predetermined time or according to specific conditions.

[0115] More specifically, the device having a harmful gas purification and recovery function according to the present invention may include a harmful substance sensor (70) installed at the discharge end of the second adsorption damper (220) to sense the concentration of harmful substances included in the discharged gas.

[0116] The concentration of the hazardous substance sensed by the hazardous substance sensor (70) will gradually increase depending on the amount of the hazardous substance adsorbed in the first chamber (110). Therefore, when the concentration of the hazardous substance sensed by the hazardous substance sensor (70) reaches a reference value, the control unit determines that regeneration (regeneration from a filter perspective) of the hazardous substance filter (40) accommodated in the first chamber (110) is necessary, and can switch the operation modes of the first chamber (110) and the second chamber (120) between each other.

[0117] However, there may be cases where the hazardous substance sensor (70) itself is broken or not equipped. To prepare for this, the present invention may further include a separate timer, and the control unit initializes the timer when each of the first chamber (110) and the second chamber (120) operates in a specific mode, and when a predetermined time has elapsed based on the timer, switches the operation modes of the first chamber (110) and the second chamber (120) to each other, thereby responding to such errors.

[0118] The present invention can be equipped with pressure sensors, temperature sensors, humidity sensors, hazardous substance sensors, and gas inflow speed sensors at various locations. For example, a pressure sensor, a hazardous substance sensor, a temperature sensor, a humidity sensor, a gas inflow speed sensor, etc. can be equipped at the front end of the pretreatment filter unit (101) described above to sense various information of the gas introduced into the device having the hazardous gas purification and recovery function according to the present invention. In addition, pressure sensors can be equipped between the pretreatment filter unit (101) and the first adsorption damper (210), and at the discharge end of the second adsorption damper (220), and temperature sensors can be equipped at the front and rear ends of the heater (710), the rear end of the catalyst (730), and the discharge end of the condenser (600).

[0119] The present invention is not limited to the above-described embodiments, and the scope of application is diverse. It goes without saying that anyone with ordinary skill in the art can make various modifications without departing from the gist of the present invention as claimed in the claims.
