(Research Institution) 2024.7.01 - 2027.12.31

[0002] The present invention relates to a regeneration device for regenerating powdered activated carbon using superheated steam.

Background Art

[0003] Generally, activated carbon is classified into powdered activated carbon and granular activated carbon according to its physical shape, and is selectively used in the fields of electronic, steel industries, solvent recovery, wastewater treatment, and treatment of air pollutants according to the treatment field and removal conditions of pollutants.

[0004] As described above, waste activated carbon used in the environment and production processes, etc., may cause secondary environmental pollution and huge economic losses if discarded as it is. Therefore, it is necessary to regenerate and reuse waste activated carbon, and currently, it is generally regenerated using methods such as vacuum regeneration, heating and desorption, chemical regeneration, solvent regeneration, substitution regeneration, and oxidative decomposition regeneration.

[0005] In places where large quantities of activated carbon are used, the most frequently used regeneration methods are low-temperature heating regeneration and high-temperature heating regeneration. Low-temperature heating regeneration is mainly used for gaseous phase applications such as solvent adsorption, while high-temperature heating regeneration is mainly used for liquid applications such as purified and wastewater.

[0006] The aforementioned high-temperature heating and regeneration method, similar to the activated carbon manufacturing process, involves heat treatment at a high temperature of 800°C to 1000°C in a rotary kiln or a multi-stage furnace, and proceeds through a drying step to dry the waste activated carbon, a high-temperature heating step to carbonize the adsorbed substances remaining in the pores of the activated carbon, and an activation step to gasify and remove the carbonized adsorbed substances from the pores using oxidizing gases such as water vapor, carbon dioxide, and oxygen.

[0007] However, because an oxidizing agent is used at high temperatures, activated carbon is lost, and in the process, micropores are destroyed and enlarged into macropores. Consequently, the adsorption capacity for substances with low molecular weight decreases, resulting in a significant reduction in the adsorption capacity of the activated carbon and a decrease in hardness. Furthermore, installing such a regeneration facility on-site requires a large space, incurs enormous facility costs, and presents the problem of performance degradation associated with regeneration.

[0008] In particular, in the case of powdered activated carbon, processing is difficult due to scattering, and due to the physical properties of the fine particles, when subjected to high-temperature heat treatment in a high-temperature multi-stage furnace or rotary kiln, it is easily carbonized and difficult to regenerate, and even after the regeneration process, its performance deteriorates significantly.

[0014] Furthermore, the separation unit D of the steam discharge module 200 may also include a separation body D1 that contains the high-temperature mixed superheated steam that has passed through the filtration unit C and forms a movement path from bottom to top, a number of splash prevention plates D2 that are spaced apart from each other inside the separation body D1, and a cleaning unit D3 that is mounted on the upper part of the separation body D1 and cleans the splash prevention plates D2 and the inside of the separation body D2.

[0015] In this case, the anti-scattering plates D2 may be arranged alternately on the inner surface of the separating body D1 in directions facing each other, maintaining a certain separation distance from the lower to the upper part of the separating body D1.

[0023] In the case of the filtration module of the present invention, it can be manufactured into a filter unit type including a granular activated carbon layer, adsorbing the powdered activated carbon to the coarser granular activated carbon for reuse, and continuously exposing the granular activated carbon layer itself in the filter unit to high-temperature superheated steam for recycling so that it can be continuously used without the hassle of replacement, and it also has the advantage that it can be recovered and used as activated carbon in the future.

[0024] Furthermore, when discharging the filtered high-temperature mixed superheated steam, in order to prevent the risk of residual powdered activated carbon from scattering and causing air pollution, an overlapping arrangement structure of scattering prevention plates is formed, so that the last remaining powdered activated carbon can be recovered, and it can be mixed with water through washing and recovered, thereby enhancing the recovery efficiency.

[0030] Figure 1 is a block diagram showing the main components constituting a powder activated carbon regeneration apparatus (hereinafter referred to as "the present invention") according to an embodiment of the present invention. Figure 2 is a cross-sectional conceptual diagram relating to the powder activated carbon regeneration apparatus according to the embodiment of the present invention described in Figure 1. Figure 3 is a perspective conceptual diagram showing an example of the implementation of the powder activated carbon regeneration apparatus according to the embodiment of the present invention described in Figures 1 and 2.

[0031] Referring to Figures 1 to 3, the present invention comprises an activated carbon regeneration module 100 having a sealed regeneration housing A into which powdered activated carbon is introduced and regenerated by injecting superheated steam into a containment space; a discharge unit B for discharging the powdered activated carbon regenerated in the activated carbon regeneration module 100; and a steam discharge module 200 for separating and discharging mixed superheated steam containing the fine powdered activated carbon used in the regeneration process via a filtration unit C.

[0032] The activated carbon regeneration module 100 includes a tank-type regeneration housing A with a sealed structure and an internal storage space. The module receives superheated steam from a supply source that supplies high-temperature superheated steam into the regeneration housing A and performs the function of regenerating powdered activated carbon, which is the material to be regenerated, by injecting the superheated steam into the housing A.

[0033] In particular, the regeneration housing A of the present invention is designed to have a lower surface A1 with an inclined structure that allows powdered activated carbon flowing in from the top to be regenerated and loaded onto the bottom surface, so that it can naturally move along the inclined surface to the discharge section B.

[0034] For this purpose, a superheated steam injection module F is further provided in the internal space of the activated carbon regeneration module 100, which is located inside the regeneration housing A. The superheated steam injection module F comprises a first injection nozzle unit F1 which is horizontally positioned in the upper region of the regeneration housing A and injects superheated steam downward, and a second injection nozzle unit F2 which is positioned away from the lower surface A1 of the regeneration housing but is inclined along the inclined structure.

[0035] Specifically, referring to Figures 2 and 3, after the powdered activated carbon, which is the material to be recycled, is introduced into the regeneration housing A via the input section 110, superheated steam flows in via the superheated steam supply section T and is injected via the first injection nozzle unit F1 and the second injection nozzle unit F2 described above.

[0036] Powdered activated carbon generally has a particle size distribution of 5 to 150 μm (100 mesh or less), and therefore has the characteristic of flowing into the regeneration housing A, scattering within the internal space, falling, and accumulating at the bottom.

[0037] Therefore, the first injection nozzle unit F1 of the present invention is arranged horizontally in the upper region of the regeneration housing A and injects superheated steam downward, with the injection nozzle positioned downward and injecting high-temperature superheated steam at high pressure to regenerate the powdered activated carbon that is scattered and distributed inside.

[0038] The regeneration process for such powdered activated carbon includes a step of supplying superheated steam to the waste activated carbon to heat and separate the organic components adsorbed on the waste activated carbon above its boiling point; a thermal decomposition step of thermally decomposing the volatile organic compound (VOC) components of the separated gas phase; and a step of restoring the micropores in the waste activated carbon to the pore distribution of activated carbon.

[0039] The second injection nozzle unit F2 of the present invention is preferably positioned along the slope of the lower surface of the regeneration housing A of the present invention, which has a sloping bottom surface structure, as shown in Figures 2 and 3.

[0040] In particular, the regeneration housing A of the present invention is designed to have a lower surface A1 with an inclined structure that allows powdered activated carbon flowing in from the top to be regenerated and loaded onto the bottom surface, so that it can naturally move along the inclined surface to the discharge section B. The second injection nozzle unit F2 is positioned away from such lower surface A1 at a certain distance S, and at the same time has an arrangement structure that is inclined along the inclined structure.

[0041] Furthermore, it is even more preferable that the second injection nozzle unit F2 includes both an upper nozzle section A, which injects superheated steam injected via the injection nozzle toward the upper part of the regeneration housing A, and a lower nozzle section B, which injects steam toward the inclined lower surface A1.

[0042] The upper nozzle section A collides with the superheated steam injected from the first injection nozzle unit F1, performing the function of stirring and mixing the powdered activated carbon inside, and further increasing the regeneration efficiency by providing more opportunities for contact with the superheated steam.

[0043] Simultaneously, in the case of the lower nozzle section B, superheated steam is injected at high pressure into the powdered activated carbon that is stacked or remaining along the inclined surface to regenerate it, and the powdered activated carbon at the bottom is lifted to the top, allowing it to come into contact with even more superheated steam.

[0044] In addition, in the case of the lower nozzle section B, an end injection section C is provided at the end of the main injection pipe m, allowing strong superheated steam to be injected along the inclined direction, making it easy for the regenerated powdered activated carbon that accumulates at the bottom to flow into the discharge section B.

[0045] Next, the present invention includes a discharge section B for guiding and discharging the regenerated powdered activated carbon in the regeneration housing A downwards. The discharge section B comprises a discharge line b1 formed downwards at the point where the inclination of the lower surface of the regeneration housing A ends, and a discharge valve b2, allowing the regenerated powdered activated carbon to be separated and recovered.

[0046] Furthermore, the high-temperature superheated steam used in the regeneration process in the regeneration housing A is discharged in a form mixed with some powdered activated carbon (hereinafter referred to as "mixed superheated steam"). The present invention can further provide a filtration unit C that can filter such mixed superheated steam to recover the regenerated powdered activated carbon mixed with the mixed superheated steam, and can also filter and discharge the high-temperature steam.

[0047] The filtration unit C is positioned adjacent to the discharge section B formed at the end of the regeneration housing A of the present invention, and as shown in Figures 3, 4, and 5, it can be a drawer type and implemented as a detachable modular structure.

[0048] Specifically, referring to Figures 2 and 3, the filtration unit C is detachably coupled to a mounting section C1 formed on one side of the activated carbon regeneration module 100 and comprises a coupling body section 210 having a number of partition spaces and a filter section 220 arranged adjacent to the granular activated carbon built-in section 216, with at least one perforating member 212 and a mesh member 214 positioned on the front surface of the coupling body section 210.

[0049] In other words, the filtration unit C is fitted to the mounting section C1 using a snap-fit ​​system, and is designed to be detachable in a pull-out type manner for replacement or retrieval, allowing for the collection or replacement of internal filter components. This makes it user-friendly and allows for easy maintenance.

[0050] Figure 4 is a conceptual diagram of the disassembled filtration unit of the present invention, and Figure 5 is a conceptual diagram of the assembled state of Figure 4. Figure 6 shows a side view of the conceptual diagram in Figure 3.

[0051] Referring to Figures 4 and 5, the filtration unit C consists of a perforated plate 212 with numerous holes formed therein to allow the mixed superheated steam to flow in and filter, based on the flow direction A' of the mixed superheated steam used for regeneration, and a mesh member 214 formed in a mesh-like structure, arranged in this order to filter out foreign matter such as carbonized material other than the superheated steam and powdered activated carbon.

[0052] In this way, the mixed superheated steam, which has been filtered multiple times, flows into the granular activated carbon layer packed in the granular activated carbon internal section 216.

[0053] The mixed superheated steam passes through the granular activated carbon layer packed in the granular activated carbon internal section 216, and the powdered activated carbon contained in the mixed superheated steam is adsorbed onto the granular activated carbon layer and separated from the superheated steam, thus undergoing a natural filtration process.

[0054] Subsequently, it is possible to separate only this granular activated carbon layer and process it as recycled activated carbon for use, or to separate and recover only the powdered activated carbon by methods such as high-pressure air injection.

[0055] The granular activated carbon layer used in this filter layer has the problem of losing its internal voids with use, requiring a process of filling it with a new granular activated carbon layer. However, in this invention, the high-temperature regeneration effect of the mixed superheated steam allows for repeated use and regeneration, significantly increasing the number of uses and the duration of use.

[0056] In other words, the high-temperature mixed superheated steam of the present invention, passing through the granular activated carbon layer, maintains almost the same temperature as that used in the regeneration process, and typically has a temperature of around 400°C. Therefore, the granular activated carbon layer itself performs the regeneration process.

[0057] Furthermore, a perforated plate 217 or a mesh member 218 may be further arranged behind the granular activated carbon built-in section 216 of the filtration unit C of the present invention, if necessary, and a further auxiliary filtration section 219 may be formed if necessary. In this case, the auxiliary filtration section 219 may further be equipped with a granular activated carbon built-in section having the granular activated carbon layer described above, and the mixed superheated steam described above may be retained in the space of the auxiliary filtration section to improve the filtration efficiency.

[0058] Furthermore, a cover C2 can be provided on the front of the filtration unit C to allow the user to manually attach and detach it, making it easier to operate.

[0059] The high-temperature mixed superheated steam that has passed through the filtration unit C is then separated into a separation unit D, which is located adjacent to the side of the regeneration housing A and has a long width in the height direction, as shown in Figures 2 and 3.

[0060] The separation unit D ensures that the mixed superheated steam, which has passed through the filtration unit C located at the bottom of the regeneration housing A, moves from the bottom to the top, and during this process, it recovers any finely powdered activated carbon remaining inside the mixed superheated steam.

[0061] For this purpose, the separation unit D of the present invention is positioned on one side of the regeneration housing A and allows the mixed superheated steam that has passed through the filtration unit C to flow through a splash-proof plate installed inside, thereby further separating the powdered activated carbon from the steam.

[0062] The mixed superheated steam flowing into the separation unit D is steam whose temperature has dropped from approximately 400°C to approximately 100°C before passing through the filtration unit C, and most of the finely mixed powdered activated carbon corresponds to regenerated activated carbon that has undergone the regeneration process.

[0063] Therefore, in the separation unit D of the present invention, a pipeline with a wide longitudinal width is realized in a sealed structure on the side of the regeneration housing A, and anti-scattering plates are arranged inside in a staggered, alternating pattern so that the mixed superheated steam collides with them and any remaining powdered activated carbon is adsorbed onto the anti-scattering plates.

[0064] To this end, the separation unit D comprises a separation body D1 which contains the high-temperature mixed superheated steam that has passed through the filtration unit C, forms a movement path from bottom to top, is positioned adjacent to the side of the regeneration housing A, and is realized as a closed-type pipeline structure having a long flow path in the height direction; a number of splash prevention plates D2 which are spaced apart from each other inside the separation body D1; and a cleaning unit D3 which is mounted on the upper part of the separation body D1 and cleans the splash prevention plates D2 and the inside of the separation body D2.

[0065] In this case, the anti-scattering plates D2 are characterized by maintaining a certain separation distance from the lower to the upper part of the separation body D1 and being arranged alternately on the inner surface of the separation body D1 in directions facing each other.

[0066] In other words, as shown in Figure 2, the scattering prevention plate D2 is configured such that the path through which the mixed superheated steam flows in is from bottom to top. This prevents some of the recycled powdered activated carbon mixed into the mixed superheated steam from colliding and scattering to the maximum extent, and instead causes it to be adsorbed onto one surface of the scattering prevention plate or to remain after colliding with it.

[0067] To achieve this, multiple anti-scattering plates are arranged alternately in positions facing each other on the inside of the separation body D1, and instead of a horizontal structure, an inclined structure (a structure with an acute inclination angle in the downward direction) is realized, thereby extending the residence time of the mixed superheated steam and improving the efficiency of the function of preventing scattering of powdered activated carbon and residual adsorption.

[0068] In particular, as shown in Figures 2 and 3, a cleaning unit D3 is positioned at the top of the separation body D1, and the powdered activated carbon adsorbed on the splash prevention plate is collected at the bottom via a spray nozzle N that sprays cleaning water into the interior of the lower part, and then discharged through the discharge port D.

[0069] As described above, the mixed superheated steam, after filtering and recovering the powdered activated carbon through the filtration unit C and the separation body D, will contain only a very small amount of dust-like activated carbon and will also contain some condensed water components.

[0070] Therefore, the mixed superheated steam that has passed through the separation body section D is moved through the transfer channel unit E. In this case, a bent region E1 is formed in one area of ​​the transport pipeline as shown in Figures 2 and 3, and the condensed water that accumulates in the bent region E is discharged through the condensed water discharge section E2.

[0071] Furthermore, the steam that has discharged condensed water flows into the dust collection module 300, where it adsorbs fine dust, and then flows into the combustion module 400 (Figure 7), where it is finally burned and discharged.

[0072] Figures 7 and 8 show the formation structure of the combustion module 400 of the present invention described above.

[0073] Referring to Figures 7 and 8, the steam from which condensed water has been discharged flows into the dust collection module 300 and adsorbs fine dust. After the fine dust is removed via the mixed superheated steam dust collection module 300, it flows into the combustion module 400 via the transport pipe 410.

[0074] The mixed superheated steam that flows into the combustion module 400 undergoes a preheating process in the heat exchanger 420. After this, the preheated air is heated to a high temperature of approximately 750°C to 1000°C in the combustion chamber via the combustion burner 430, where harmful gases such as volatile organic compounds (VOCs) are burned.

[0075] In other words, since the harmful gases generated during the regeneration process are also contained within the high-temperature superheated steam, pollutants such as volatile organic compounds (VOCs) can be burned at high temperatures and converted into carbon dioxide (CO2) and water (H2O) to be removed.

[0076] In this case, a heat exchanger is used to recover the heat generated during the combustion process, which is then reused in the process to improve energy efficiency, reduce operating costs, and ensure environmental friendliness by releasing purified steam.

[0077] Although the present invention has been described above based on preferred embodiments, the technical idea of ​​the present invention is not limited thereto, and it is obvious to a person with ordinary skill in the art to which the present invention belongs that modifications and changes can be made within the scope of the claims, and such modifications and changes can be said to fall within the scope of the appended claims.
