[0002] The present invention relates to an integrated system for activated carbon regeneration and regeneration emissions treatment, and more specifically, to a system that can apply automatic waste carbon discharge and regenerated carbon input equipment, as well as waste carbon / regenerated carbon conveying devices, to a large-capacity water treatment activated carbon filtration system, and is capable of not only automatically regenerating activated carbon but also integrally operating water treatment. In particular, the present invention relates to a system that includes a technology for removing emissions from the regeneration process by introducing a combustion process.
Background Art
[0003] Wastewater treatment facilities that purify various types of sewage and wastewater, such as domestic sewage and industrial wastewater, to a certain level and discharge them operate by passing the sewage and wastewater through a water treatment tank filled with an adsorbent, and adsorbing harmful components contained in the sewage and wastewater with the adsorbent to purify the water. Usually, as the adsorbent filled in the water treatment tank, most are amorphous substances composed mainly of carbon, and activated carbon with a high specific surface area, high adsorption capacity, and excellent ability to remove harmful substances is mainly used.
[0004] In industrial wastewater treatment facilities, activated carbon, used as an adsorbent, experiences a rapid decline in its water purification capacity after a certain period as organic matter fills the voids formed on its surface. Therefore, activated carbon is currently replaced or regenerated periodically.
[0005] Typically, in large-scale facilities that treat large volumes of wastewater, the most burdensome aspect, both in terms of cost and facility operation, is the regeneration of activated carbon. Recently, there has been a growing trend to actively work towards ensuring overall facility operational efficiency by organically linking wastewater treatment operations and activated carbon regeneration operations.
[0006] Currently, the activated carbon regeneration method involves removing waste carbon from the water treatment tank, transporting it over long distances off-site, regenerating it at an activated carbon regeneration facility, and then returning it to its original location and putting it back into the water treatment tank. This method of activated carbon regeneration has several drawbacks: it not only incurs significant costs due to delays and prolonged regeneration processes, but also reduces the operating rate of the water treatment facility, such as delays in the operation of the water treatment tanks; and it also results in substantial economic losses due to the high rate of activated carbon loss during the regeneration process.
[0007] For this reason, the applicant has proposed a novel integrated wastewater treatment system through Korean Registered Patent No. 10-2092542, which includes a device that automatically discharges and transports waste coal using air and high-pressure water between a water treatment facility and an activated carbon regeneration facility, and automatically feeds in regenerated coal.
[0008] However, in the case of the applicant's Korean registered patent No. 10-2092542 technology, while it is economically efficient and can construct a system by integrating the operation of a water treatment facility comprising multiple water treatment tanks and an activated carbon regeneration facility comprising multiple activated carbon regeneration tanks, it has the limitation that it cannot completely eliminate the activated carbon loss that occurs at a certain rate during the transportation of waste activated carbon and regenerated activated carbon. Furthermore, because there is no system configuration for treating the wastewater, waste steam, exhaust gas, and other emissions generated during activated carbon regeneration, there is a strong need for environmentally friendly treatment technology.

[0009] [Patent Document 1] Korean Registered Patent Publication No. 10-2092541 [Patent Document 2] Korean Registered Patent Publication No. 10-2092542 [Overview of the project] [Problems that the invention aims to solve]
[0010] The present invention was devised to solve the above-mentioned problems, and its purpose is to improve the efficiency of transporting waste coal and recycled coal, minimize the loss rate of waste coal and recycled coal, and to provide an integrated system that can construct an environmentally friendly recycling system by adjusting the mixing ratio of water and activated carbon when transporting waste coal discharged from a water treatment tank and when transporting recycled coal supplied from an activated carbon recycling tank, and by transporting the mixed mixture via a hose pump unit. [Means for solving the problem]
[0011] A means to solve the above-mentioned problems, an integrated system for activated carbon regeneration and regeneration waste treatment using superheated steam according to an embodiment of the present invention, as shown in Figures 1 to 5, comprises: a superheated steam forming module that generates superheated steam and supplies superheated steam via piping; an activated carbon regeneration module 100 that receives superheated steam supplied from the superheated steam forming module and performs regeneration by injecting it through superheated steam injection modules S:S1, S2 which are capable of injecting superheated steam into waste activated carbon contained inside; and an exhaust water treatment module W that stores the waste water generated in the activated carbon regeneration module 100 and mixes the exhaust steam discharged from the activated carbon regeneration module 100 and the exhaust gas supplied from the combustion module 400 with the waste water for combustion treatment. [Effects of the Invention]
[0012] According to embodiments of the present invention, when transporting waste coal discharged from a water treatment tank and when transporting regenerated coal supplied from an activated carbon regeneration tank, the mixing ratio of water and activated carbon is adjusted, and a method is adopted in which the mixed mixture is transported via a hose pump unit. This makes it possible to increase the transport efficiency of waste coal and regenerated coal, minimize the loss rate of waste coal and regenerated coal, and also make it possible to construct an environmentally friendly regeneration system by treating and burning the wastewater, exhaust steam, and waste vapors generated in the process of regenerating activated carbon in a manner appropriate to the process stage.
[0013] In particular, it has the advantage of eliminating pollution risks in the regeneration process by separating the wastewater, waste steam, and exhaust gas generated during the regeneration process into quantitative mixed gases and burning them in the combustion module, thereby enhancing environmental friendliness.
[0014] Furthermore, by incorporating a mixing chamber that mixes the high-temperature exhaust gas generated in the combustion module with exhaust water (condensed water) and exhaust steam, and by performing quantitative injection to burn the gas, combustion efficiency can be increased, and the utilization of thermal energy can be made more efficient.
[0015] Furthermore, according to the present invention, by integrally operating the water treatment facility to which a plurality of water treatment tanks belong and the activated carbon regeneration facility to which a plurality of activated carbon regeneration tanks belong, and applying a new system for organically discharging and inputting waste carbon and regenerated carbon between the water treatment facility and the activated carbon regeneration facility, the efficiency of system operation can be improved, the system can be economically operated, the loss rate of activated carbon can be reduced, and in addition, there is an effect that the operating rate of the water treatment facility can be increased.

Embodiments for Carrying Out the Invention
[0017] The advantages, features, and the ways to achieve them of the present invention will become clearer by referring to the embodiments described in detail below in conjunction with the accompanying drawings. However, the present invention is not limited to the embodiments described herein and can also be embodied in other forms. Instead, the embodiments introduced here are provided to ensure that the disclosed content is thorough, complete, and can fully convey the idea of the present invention to those skilled in the art.
[0018] Hereinafter, the present invention will be described in detail based on the accompanying drawings.
[0019] FIG. 1 is a plan view showing the layout of an integrated system for activated carbon regeneration and regeneration exhaust gas treatment using superheated steam according to an embodiment of the present invention (hereinafter referred to as "the present invention"), and FIG. 2 is a block diagram showing the line configuration of an integrated system for activated carbon regeneration and water treatment according to an embodiment of the present invention.
[0020] As shown in FIG. 1, the integrated system for activated carbon regeneration and water treatment using superheated steam of the present invention is a new integrated wastewater treatment system that integrally operates a large-scale water treatment facility belonging to a plurality of water treatment tanks and a minimum activated carbon regeneration facility belonging to a plurality of activated carbon regeneration modules with activated carbon regeneration tanks, efficiently discharges and conveys waste carbon using a hose pump unit between the water treatment facility and the activated carbon regeneration facility, and automatically inputs regenerated carbon. It is a new integrated wastewater treatment system that integrally operates a large-scale water treatment facility belonging to a plurality of water treatment tanks and a minimum activated carbon regeneration facility belonging to a plurality of activated carbon regeneration modules with activated carbon regeneration tanks, performs waste carbon discharge and conveyance with the loss rate minimized, and automatically inputs regenerated carbon.
[0021] In other words, the present invention comprises an activated carbon regeneration module 100 comprising: a plurality of water treatment tanks 1A for adsorbing and treating impurities contained in wastewater; a waste carbon storage tank 11 for storing waste carbon discharged from the water treatment tanks 1A; and at least one activated carbon regeneration tank for regenerating activated carbon supplied from the waste carbon storage tank 11; and a regenerated carbon storage tank 13 for storing the regenerated carbon discharged from the activated carbon regeneration module 100 and then supplying it to the water treatment tanks 1A.
[0022] The water treatment tank 10 is a facility that purifies wastewater by passing it through an adsorbent, such as activated carbon, which is filled inside the tank, thereby adsorbing harmful components in the wastewater before discharging it. Unlike ordinary water treatment tanks that simply treat wastewater without a facility for regenerating activated carbon, the water treatment tank 10 has a mechanism that allows for the discharge of activated carbon for regeneration and the input of regenerated activated carbon. This is advantageous not only from a structural standpoint but also from the standpoint of operational efficiency.
[0023] In the present invention, as shown in Figure 2, the treatment operation in the conventional water treatment tank 10 is realized by adopting the structure of the existing invention. However, in the transport process for transporting waste coal, instead of the existing pressure tank and high-pressure water discharge method, transport pump units 20A, 20B, and 20C equipped with a hose pump unit are adopted to transport waste coal or the regenerated activated carbon described later, thereby minimizing the loss of activated carbon.
[0024] The transport pump units 20:20A, 20B, and 20C of the present invention, used in such a hydraulic transport process, preferably comprise, as shown in Figure 3, an inlet 22 for introducing a mixed substance of water and activated carbon or waste activated carbon into the elastic hose 230, achieving a water:(activated carbon or waste activated carbon) mixing ratio within a standard range of 1:1.3 to 2.0 by volume, a crimping roller 25 for performing crimping and rolling operations while pressing the elastic hose 23, and a rotary drive unit 25a for rotating the crimping roller 25. (Hydroelectric transport means transporting a mixture of water and activated carbon.)
[0025] In other words, the transport pump unit 20 is a device structure that can replace an existing pressurized tank for forcibly transporting waste coal discharged from the water treatment tank 10 to the waste coal storage tank 11. It is fitted with an elastic hose 23, and the rotation of the compression roller 25 causes the elastic hose and the compression roller to come into contact with each other and compress the hose. The elastic hose is compressed and then restored, generating a strong suction force, which can be used to suck up and transport waste coal or activated regenerated coal.
[0026] Such a transport method makes it possible to transport mixtures of water and waste carbon in a water treatment tank, and mixtures of regenerated activated carbon and water in an activated carbon regeneration tank, through powerful suction and discharge forces. In this case, the water:(activated carbon or waste activated carbon) mixing ratio of the mixed substance, in which water and activated carbon or waste activated carbon are mixed, may be set to a standard range of 1:1.3 to 2.0 by volume.
[0027] Most preferably, the water-to-(activated carbon or waste activated carbon) ratio of the mixed material, in which water and activated carbon or waste activated carbon are mixed, is in the range of 1:1.5 by volume. Within this range, if the proportion of water is too high, the viscosity will decrease and affect the suction force, and if the proportion of water is too low, the viscosity of the mixture with activated carbon will increase, hindering transport and causing the activated carbon to break down. Therefore, it is preferable to adjust the mixing ratio of water and waste carbon (or activated carbon) to the above-mentioned optimal range. This allows for checking the mixing ratio of the incoming mixture in real time and controlling the efficient transport process by allowing water to flow in or out within the above-mentioned optimal range. By adjusting the mixing ratio of water and activated carbon in this way and adopting a method of transporting the mixed mixture via a hose pump unit, the transport efficiency of waste carbon and recycled carbon can be increased, and the loss rate of waste carbon and recycled carbon can be minimized.
[0028] Figure 4 shows the arrangement of the main components of the present invention as described in Figures 1 to 3. In particular, Figure 4 is a conceptual diagram showing the main components arranged around the structure of the activated carbon regeneration module 100 of the present invention.
[0029] Referring to Figures 1 to 4, in this invention, waste coal is transported from the water treatment tank 10 to the coal storage tank 11 via the first transport pump unit 20A, and then flows from the waste coal storage tank 11 to the activated carbon regeneration tank T shown in Figure 4 via the second transport pump unit 20B through the inflow section 13a at the top.
[0030] The activated carbon regeneration tank T contains waste activated carbon and performs functions such as washing the contained waste activated carbon, dewatering and drying the waste activated carbon by hydraulic transport, and regeneration using the injection of superheated steam.
[0031] Needless to say, the process stages that occur during this regeneration process are treated accordingly, with treatment carried out according to the amount and characteristics of the waste products generated in the initial stages of the process. As shown in Figure 5, the wastewater treatment module W is used to purify the waste products, and at the same time, the waste products are oxidized via the combustion module 400.
[0032] In one embodiment of the present invention, the activated carbon regeneration tank of the activated carbon regeneration module 100 may have a large number of superheated steam injection modules S:S1, S2 arranged vertically inside, as shown in Figure 4.
[0033] The superheated steam supplied to the superheated steam injection modules S:S1 and S2 is formed in a superheated steam forming module 40 located outside the activated carbon regeneration tank T. The superheated steam injection modules S:S1 and S2 can supply superheated steam to the waste activated carbon via a number of superheated steam supply modules 120a, 120b, 120c, and 120d, each equipped with a superheated steam supply line 125 that communicates with the activated carbon regeneration tank T.
[0034] Needless to say, the arrangement structure of the superheated steam injection modules S:S1 and S2 in this embodiment is not limited in any way to the present invention, and various modifications of the nozzle structure that supplies superheated steam in a spray form inside the activated carbon regeneration tank can be applied.
[0035] In the present invention, the superheated steam injection module S1, which injects superheated steam, is supplied with superheated steam formed using the superheated steam formation module 40 via the superheated steam supply line 125, and the supply of superheated steam can be controlled using the respective superheated steam supply valves 121, 122, 123, and 124.
[0036] When the activated carbon regeneration process is carried out using the injection of superheated steam, the discharged substances (hereinafter referred to as "discharged substances") such as wastewater, exhaust steam, and waste exhaust gas generated during the regeneration process are discharged to the outside of the activated carbon regeneration tank T. In this invention, the discharged substances discharged from the activated carbon regeneration tank T are purified via a wastewater treatment module W.
[0037] Figure 5 is a conceptual diagram illustrating the main components of the present invention that perform the process of treating wastewater generated after activated carbon regeneration in the activated carbon regeneration module 100 equipped with the activated carbon regeneration tank T of the present invention as shown in Figure 4.
[0038] Referring to Figures 4 and 5, this embodiment includes an activated carbon regeneration module 100 equipped with an activated carbon regeneration tank T into which waste activated carbon is fed and regenerated by injecting superheated steam into a containment space, and a steam discharge module 200 that separates and discharges the superheated steam used in the regeneration process. Furthermore, it includes a combustion module 400 that is linked to a wastewater treatment module W.
[0039] In other words, the present invention preferably comprises a wastewater treatment module W comprising: a wastewater storage tank 310 for storing wastewater generated in an activated carbon regeneration module 100 that regenerates waste activated carbon by injecting superheated steam; a demister box section 320 into which exhaust steam generated in the activated carbon regeneration module 100 flows and removes moisture and dust; a mixing chamber section 330 into which condensed water stored in the wastewater storage tank 310 is transported via a piping line and contains and mixes exhaust steam discharged from the activated carbon regeneration module and exhaust gas supplied from a combustion module 400; and a combustion module 400 for transporting and burning a gaseous mixed gas formed by mixing the condensed water, exhaust steam, and exhaust gas mixed in the mixing chamber section 330.
[0040] The activated carbon regeneration module 100 is a device that houses waste activated carbon, performs a washing process for the housed waste activated carbon, dewaters and dries the waste activated carbon by hydraulic transport, and regenerates it using the injection of superheated steam. The device is designed to discharge condensed water and exhaust steam during the regeneration process.
[0041] As an example, as described above by the applicant in Figures 1 and 2, there is a structure such as an activated carbon regeneration tank that regenerates waste activated carbon by injecting superheated steam into it. However, the present invention is not limited to this in any way, and as long as it is a device that performs a regeneration process using superheated steam, it is considered to fall within the scope of the activated carbon regeneration module of the present invention.
[0042] Depending on the arrangement structure of the activated carbon regeneration module 100, a steam discharge module 200 for discharging high-temperature exhaust steam generated in the activated carbon regeneration module may be selectively provided, and a dust collection module for filtering dust and contaminants contained in the exhaust steam may also be selectively provided.
[0043] In particular, the present invention is characterized by comprising, as described above, an exhaust water treatment module W for treating condensed water and exhaust steam discharged from the activated carbon regeneration module 100, and a combustion module 400 for mixing the condensed water and exhaust steam in gaseous form, injecting it, and burning it.
[0044] Preferably, such a wastewater treatment module W comprises a wastewater storage tank 310 for storing water discharged from activated carbon or condensed water (hereinafter referred to as "wastewater") obtained by condensing such water in an activated carbon regeneration module 100 that regenerates waste activated carbon by injecting superheated steam into it; a demister box section 320 into which exhaust steam generated in the activated carbon regeneration module 100 flows to remove water and dust; and a mixing chamber section 330 into which the wastewater stored in the wastewater storage tank 310 is transported via a piping line and which contains and mixes the exhaust steam discharged from the activated carbon regeneration module and the exhaust gas supplied from the combustion module 400.
[0045] In the case of the wastewater treatment module W in a preferred embodiment of the present invention, the amount of wastewater and exhaust gases generated differs as the regeneration process progresses in the activated carbon regeneration module 100. Therefore, in order to efficiently treat the exhaust gases, the integrated control module 500 is used to distinguish between the storage, discharge, and combustion processes of the exhaust gases for treatment.
[0046] 1. Processing of waste in the initial section of the regeneration process. In the activated carbon regeneration module 100, when waste activated carbon is regenerated, the regeneration process is carried out by injecting superheated steam into the waste activated carbon. In the initial regeneration section, within 3 hours from the start of the regeneration process, there is a characteristic that wastewater is discharged very actively, while exhaust steam is not generated very actively.
[0047] In contrast, during the later stages of the regeneration process, 3 to 5 hours after the start of the waste activated carbon regeneration process, a unique characteristic arises: the amount of wastewater discharged decreases, while the amount of exhaust steam and exhaust gas increases.
[0048] Therefore, in the present invention, during the initial regeneration phase within 3 hours of the start of the waste activated carbon regeneration process, the generated wastewater is treated by collecting it in the wastewater storage tank 310, and the generated exhaust steam is treated by passing it through the demister box section 320 and the mixing chamber section 330, oxidizing it to over 900°C in the combustion module 400, and then discharging it into the atmosphere.
[0049] Furthermore, in the later stages of regeneration, 3 to 5 hours after the start of the waste activated carbon regeneration process, the generated exhaust steam is fed into the demister box section 320 and the mixing chamber section 330, and the generated condensed water is formed into a mixed gas in the mixing chamber section, and quantitative injection is performed while maintaining the temperature above 100°C, oxidizing it to above 900°C in the combustion module 400 before being discharged into the atmosphere.
[0050] 2. Treatment of waste products in the later stages of the regeneration process Based on Figure 6, the operation process of the wastewater treatment module W of the present invention will be described in detail.
[0051] Figure 6 is a procedure diagram and a conceptual diagram illustrating the drive system of the present invention in the initial regeneration phase, within 3 hours from the start of the regeneration process of waste activated carbon.
[0052] Specifically, referring to the process procedure diagram shown in Figure 6, when the regeneration process is started in the activated carbon regeneration module 100, exhaust steam (120°C or higher) and a large amount of discharged water are generated in the initial regeneration section (hereinafter referred to as the "initial regeneration section") within 3 hours from the start of the waste activated carbon regeneration process.
[0053] In this initial regeneration section, the discharged wastewater is stored in the wastewater storage tank 310 (path y1), and the discharged exhaust steam passes through the demister box section 320, where dust and moisture are removed (path x1), and then flows along the piping line through path x2 to the mixing chamber section 330 (path x2).
[0054] The mixing chamber section 330 is defined as a component comprising all parts such as piping lines, valves, and spray nozzles connected to the mixing chamber section. Here, in the case of a mixing chamber, it is a chamber having a sealed structure, with a containment space for mixing provided inside, into which vaporized discharge water can be flowed via an external discharge water spray nozzle.
[0055] Furthermore, the containment space is used as a space into which exhaust steam and exhaust gas (high temperature), described later, can be introduced and mixed. In this case, the exhaust steam has a temperature of 120°C or higher, 110°C or higher in the section passing through the demister box section 320, and 110°C or higher when it flows into the mixing chamber section 330.
[0056] The exhaust steam that flows in in this manner passes through the mixing chamber section 330 and flows into the combustion module 400 (path x3~x4). After this, it is oxidized to over 900°C in the combustion module 400 and discharged into the atmosphere (path x6).
[0057] In this case, it is also possible to place a heat exchanger at the rear end of the gas inlet section 410 to lower the temperature of the discharged gas.
[0058] Figure 7 is a procedure diagram and process diagram showing the operation process of the present invention in the case of the late regeneration section (hereinafter referred to as the "late regeneration section") 3 to 5 hours after the start of the regeneration process of waste activated carbon.
[0059] Referring to Figure 7, in the later regeneration section, the wastewater discharged in the initial regeneration section of the present invention is stored in the wastewater storage tank 310 (path y1), and the discharged exhaust steam passes through the demister box section 320, where dust and moisture are removed (path x1), and then flows into the mixing chamber section 330 via path x2 along the piping line (path x2). The movement path of the exhaust steam is the same as that of the initial regeneration section described above.
[0060] However, in the later regeneration section, the amount of condensate discharged decreases, and the condensate is transported from the discharge water storage tank 310 via the condensate pump 315 and quantitatively sprayed into the mixing chamber section 330 via a spray nozzle (y2 path).
[0061] The condensed water injected in this manner is mixed with the exhaust steam flowing into the mixing chamber, and at the same time, it is mixed with the exhaust gas (having a temperature of 800°C or higher) flowing in through the exhaust gas circulation section 440 of the combustion module 400, which will be described later, to form a gaseous mixture (hereinafter referred to as "mixed gas").
[0062] Thus, the process of circulating a portion of the exhaust gas to the mixing chamber to form a mixed gas is carried out without providing a separate heating source. The mixed gas, which is formed by mixing the discharged water, exhaust steam, and exhaust gas from the mixing chamber 330 and heated to a temperature of 100°C or higher, is then transported to the combustion module 400 while maintaining a temperature of 100°C or higher (path x7~x8).
[0063] Thus, the process of circulating a portion of the exhaust gas to the mixing chamber allows the mixed gas to be formed at a high temperature, thereby increasing combustion efficiency, and enables highly efficient heat utilization by vaporizing condensed water into a gaseous state and oxidizing it.
[0064] In this way, the mixed gas, which is a mixture of the water discharged from the mixing chamber section 330, exhaust steam, and exhaust gas at a temperature of 100°C or higher, is transported to the combustion module 400 while maintaining a temperature of 100°C or higher (path x7~x8).
[0065] In the combustion module 400, a combustion process is carried out at a temperature of 900°C or higher using a combustion device 430 such as a combustion burner to remove malodorous substances and air pollutants, and the mixed gas is burned in the combustion section 420 before being discharged (path x9).
[0066] By using the above process, condensate generated during the regeneration process in the later stages of regeneration can be removed by burning it as a gaseous mixture in the combustor. This eliminates the need for separate treatment systems or chemicals to process the condensate, making it easy and safe to treat. As a result, process efficiency can be improved, process costs can be reduced, and the system can be made more environmentally friendly.
[0067] It goes without saying that the wastewater treatment processes shown in Figures 5 to 7 above can be adopted in the process of oxidizing the condensate in the regeneration equipment with an activated carbon regeneration tank structure, as shown in Figure 2 above.
[0068] In the case of the wastewater treatment module W of the present invention, it is possible to employ it to perform the function of receiving and treating condensate from not only such conventional activated carbon regeneration equipment, but also equipment that regenerates waste activated carbon using various superheated steams.
[0069] 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.
