Abstract
Description
Technology Field
[0001] The present invention relates to a regeneration facility device that implements the regeneration of activated carbon through dry transfer in a facility that regenerates spent activated carbon using superheated steam. Background Technology
[0002] Generally, a wastewater treatment facility is a facility that purifies various types of wastewater, such as domestic sewage or industrial wastewater, to a certain level before discharging it.
[0003] These wastewater treatment facilities operate by passing wastewater through a water treatment tank filled with an adsorbent to purify the water by adsorbing harmful components contained in the wastewater.
[0004] Activated carbon, an amorphous material composed mostly of carbon that has a large specific surface area and adsorption capacity and excellent ability to remove harmful substances, is commonly used as an adsorbent in water treatment tanks.
[0005] Activated carbon is a porous carbonaceous material used as an adsorbent for various purposes. It is utilized in the chemical industry for purification, removal of hazardous substances, decolorization, and extraction and separation. Furthermore, demand for it is continuously increasing across diverse industrial sectors, including applications in water treatment, wastewater treatment, exhaust gas adsorption, and solvent recovery to prevent environmental pollution such as air, waste, and water contamination.
[0006] As such, activated carbon used as an adsorbent in most industrial wastewater treatment facilities undergoes a rapid decline in its ability to purify pollutants after a certain period as organic matter fills the pores formed on its surface; consequently, the activated carbon is currently being periodically replaced or regenerated.
[0007] Typically, in large-scale facilities treating large volumes of wastewater, the most burdensome aspect in terms of cost and operation is the regeneration of activated carbon; consequently, there is a growing trend to make significant efforts to ensure overall operational efficiency by organically linking wastewater treatment operations with activated carbon regeneration operations.
[0008] The current activated carbon regeneration method involves removing waste carbon from the water treatment tank, transporting it over a long distance to an external regeneration facility for regeneration, and then transporting it back to its original location to be fed into the tank. This method has several disadvantages: the time required for the regeneration process is delayed and prolonged, resulting in a significant financial burden; it also leads to a decrease in the operating rate of the water treatment facility due to delays in the operation of the tank; and it is also economically disadvantageous due to a high loss rate of activated carbon during the regeneration process.
[0009] Accordingly, the applicant has proposed a new integrated wastewater treatment system through Korean registered patents No. 10-2092542 and No. 10-2425430, which installs a device that uses air and high-pressure water between a water treatment facility and an activated carbon regeneration facility to mix waste carbon with water, transport it in a wet manner, and automatically feed regenerated carbon.
[0010] While this wet transfer method offers the advantage of minimizing the loss rate of spent activated carbon, there is a problem in that excessive condensate is generated in the process of introducing spent activated carbon mixed with water into a regeneration tank and regenerating it through superheated steam, which prolongs the process time and increases wastewater generation.
[0011] In addition, due to the wet transport of spent activated carbon, blockage of the pipeline occurs during transport, and costs increase due to excessive water usage. Furthermore, even after the regeneration process is completed, the process of cooling the regenerated carbon inside the regeneration tank is performed, which causes the process time to become excessively long. Prior art literature
[0012] Korean Registered Patent No. 10-2092542, Korean Registered Patent No. 10-2425430 The problem to be solved
[0013] The present invention was devised to solve the aforementioned problems, and the objective of the present invention is to provide a dry activated carbon regeneration facility that can eliminate problems such as excessive generation of condensed wastewater, blockage of the transfer pipeline, and delay of process time by implementing a facility structure that can transfer saturated activated carbon to a regeneration tank in a dry manner and regenerate it using superheated steam. means of solving the problem
[0014] As a means to solve the above-mentioned problem, an embodiment of the present invention provides a dry activated carbon regeneration device comprising: a waste activated carbon supply module (100) that dry-transports waste activated carbon introduced into a storage tank through a transfer conveyor from the storage tank as shown in FIG. 1; an activated carbon regeneration module (200) that receives the waste activated carbon dry-transported from the saturated activated carbon supply module (100) into a regeneration tank and performs a regeneration process by injecting superheated steam into the regeneration tank; a cooling treatment module (300) that rotates a discharge scraper unit disposed inside the regeneration tank to receive and cool the regeneration carbon discharged to the bottom of the regeneration tank in a cooling hopper; and a regeneration carbon discharge module (400) that receives the regeneration carbon cooled in the cooling treatment module (300) into a drain hopper after drainage treatment and discharges it through a quantitative transfer conveyor.
[0015] In this case, the dry activated carbon regeneration device may be implemented as a dry activated carbon regeneration device further comprising an exhaust combustion module (500) that introduces and burns to remove exhaust including exhaust steam discharged from the regeneration tank (210) or the cooling hopper (310).
[0016] In addition, the activated carbon regeneration module (200) of the present invention can provide a dry activated carbon regeneration device comprising: a regeneration tank (210) having an internal receiving space; a superheated steam injection unit (220) having a plurality of injection pipe structures (220A, 220B) disposed inside the regeneration tank (210) and having injection nozzles (222) for injecting superheated steam; and a regeneration carbon discharge unit (230) having a discharge scraper unit (S) coupled to the lower part of a rotating central shaft (P) that rotates and is disposed axially in the center of the regeneration tank (210) and rotated.
[0017] Furthermore, the discharge scraper unit (S) of the present invention can be implemented with a rotating bar (232) that rotates in conjunction with the central rotation axis (P) and a scraper member (234) that is angle-adjustable and coupled to the lower part of the rotating bar (232) to move the regenerated bullet in the direction of the central rotation axis (P).
[0018] In addition, the cooling treatment module (300) of the present invention may provide a dry activated carbon regeneration facility device comprising: a cooling hopper (310) for receiving regenerated carbon discharged from a regenerated carbon discharge unit (242, 244) formed at the bottom of the regeneration tank (210); a cooling water supply unit (W) for supplying cooling water into the interior of the cooling hopper (310); and an ejector (J) for combining and transporting the cooled regenerated carbon discharged from the cooling hopper (310) with process water.
[0019] In addition, the exhaust combustion module (500) of the present invention can provide a dry activated carbon regeneration device comprising: a mixing chamber (510) that collects and receives exhaust (x1, x2) including exhaust steam discharged from the regeneration tank (210) and exhaust steam (y) generated during cooling in the cooling hopper (310); an inlet (520) that introduces the exhaust flowing in from the mixing chamber (510) into the combustion chamber (530); and a combustor (540) that combusts the exhaust flowing in from the inlet (520) into the combustion chamber.
[0020] Furthermore, the above-mentioned exhaust combustion module (500) can be implemented as a dry activated carbon regeneration device that supplies combustion gas (a3) generated during the combustion process of the exhaust to the mixing chamber (510) and controls the temperature inside the mixing chamber (510) to increase. Effects of the invention
[0021] According to an embodiment of the present invention, by transporting spent activated carbon in a dry manner and regenerating it through superheated steam, the amount of condensate generated during regeneration due to wet transport of spent activated carbon can be significantly reduced, and the clogging phenomenon during transport due to wet transport of spent activated carbon can be improved, thereby increasing process efficiency.
[0022] In addition, the regeneration process time generated during wet transfer can be significantly reduced, allowing for immediate removal after regeneration is complete and external cooling, thereby greatly increasing the operating time of the regeneration tank and improving process efficiency.
[0023] In addition, to improve process efficiency and prevent pressure rise in the regeneration tank during the regeneration process, exhaust steam generated during the process is discharged and burned to eliminate it, thereby simplifying the process equipment and realizing the advantage of significantly reducing odors and wastewater generation.
[0024] In addition, a rapid cooling process using cooling water is implemented after the regeneration process to improve excessive cooling time, and a wet transfer method is applied only in the discharge and return process to improve stability during the transfer and return of activated carbon, while also enabling the significant reduction of water usage.

[0026] The advantages and features of the present invention and the methods for achieving them will become clear by referring to the embodiments described below in detail together with the accompanying drawings. However, the present invention is not limited to the embodiments described herein and may be embodied in other forms. Rather, the embodiments introduced herein are provided to ensure that the disclosed content is thorough and complete and to ensure that the spirit of the present invention is sufficiently conveyed to those skilled in the art.
[0027] The present invention will be described in detail below with reference to the attached drawings.
[0028] FIG. 1 is a main block diagram of a dry activated carbon regeneration facility device according to an embodiment of the present invention (hereinafter referred to as the "present invention"). FIG. 2 is a conceptual diagram of a facility illustrating an embodiment of the present invention of FIG. 1. FIG. 3 to 9 are detailed conceptual diagrams for explaining the detailed configuration of the conceptual diagram of FIG. 2.
[0029] The present invention allows for the dry transfer of spent activated carbon and its regeneration through superheated steam, thereby significantly reducing the amount of condensate generated during regeneration due to the wet transfer of spent activated carbon, and improving process efficiency by preventing clogging during transfer caused by the wet transfer of spent activated carbon.
[0030] To this end, the present invention provides a dry activated carbon regeneration device comprising: a spent activated carbon supply module (100) that dry-transports spent activated carbon introduced into a storage tank via a conveyor belt from the storage tank as shown in FIGS. 1 and 2; an activated carbon regeneration module (200) that receives the spent activated carbon dry-transported from the spent activated carbon supply module (100) into a regeneration tank (210) and performs a regeneration process by injecting superheated steam into the regeneration tank; a cooling treatment module (300) that receives and cools the regeneration carbon discharged to the bottom of the regeneration tank by rotating a discharge scraper unit (S) placed inside the regeneration tank in a cooling hopper (310); and a regeneration carbon discharge module (400) that receives the regeneration carbon cooled in the cooling treatment module (300) into a drain hopper after drainage treatment and discharges it via a quantitative conveyor belt.
[0031] In particular, the present invention may further include an exhaust combustion module (500) that introduces and burns to remove exhaust materials, including exhaust steam discharged from the regeneration tank (210) or the cooling hopper (310), so that the exhaust steam generated during the regeneration process of dry activated carbon within the regeneration tank of the dry activated carbon regeneration facility can be treated by oxidizing it in a combustion manner to significantly reduce the generation of odor and wastewater.
[0032] FIG. 3 is a conceptual diagram for explaining the structure and operation method of the spent activated carbon supply module (100) of the present invention.
[0033] Specifically, the spent activated carbon supply module (100) of the present invention collects saturated activated carbon (hereinafter referred to as 'spent activated carbon') saturated through the use of activated carbon, as shown in FIGS. 2 and 3, and stores it in a saturated carbon storage tank (110) using a device such as a transfer crane (C). Since dry transfer is performed in the storage state rather than a wet method, a separate water treatment process is not required. The spent activated carbon is transferred from the saturated carbon storage tank (110) to a quantitative hopper (122) via a transfer conveyor (120), and after quantitative transfer, the transferred spent activated carbon is introduced into the inlet (201) at the top of the regeneration tank (210). The inlet method allows for the application of a dry pneumatic transfer method through a piping line.
[0034] The regeneration tank (210) of the above-mentioned activated carbon regeneration module (200) receives spent activated carbon flowing into the inlet (201) and supplies superheated steam to the spent activated carbon to perform a regeneration process. In this case, in the conventional wet transfer method, a process of discharging water mixed with the spent activated carbon must be performed first, but in the present invention, the regeneration process can be started immediately without a drainage process for the spent activated carbon flowing in via dry transfer.
[0035] For this regeneration process, the activated carbon regeneration module (200) may be configured to include a regeneration tank (210) having an internal receiving space, a plurality of superheated steam injection pipes (220) disposed inside the regeneration tank (210) and having injection nozzles (222) that inject superheated steam, and a regeneration carbon discharge unit (230) having a discharge scraper unit (S) that is coupled to the lower part of a rotating central shaft (P) that rotates axially disposed in the center of the regeneration tank (210) and rotates.
[0036] FIG. 4 is a conceptual diagram for explaining the structure and operation method of the activated carbon regeneration module (200) of the present invention. FIG. 5 is a planar conceptual diagram for explaining the arrangement structure of the superheated steam injection unit inside the activated carbon regeneration module (200) of the present invention.
[0037] Specifically, referring to FIGS. 2, 4, and 5, the regeneration tank (210) is a tank structure with a width of 3m to 4m and a height of 5m to 7m, and has a receiving space inside. When waste activated carbon is received inside the receiving space, a superheated steam injection unit (220) is positioned to introduce superheated steam (h1, h1) into the receiving space from an external superheated steam supply device.
[0038] The above superheated steam injection unit (220) may have multiple injection pipe structures (220A, 220B) that inject superheated steam into a receiving space inside a regeneration tank arranged in a stacked, spaced manner, as shown in FIGS. 4 and 5. An example of a structure in which a pair of sets of injection pipe structures (220A, 220B) are arranged as shown in FIG. 5 is described as follows.
[0039] The above injection pipe structure (220A, 220B) may have a plurality of auxiliary injection pipes (D1, D2, D3, E1, E2, E3) branched out horizontally around a main injection pipe (D1, E1) into which superheated steam (h1, h2) is introduced, and an injection nozzle part (222) for injecting superheated steam may be formed in the lower or upper direction of the main injection pipe and the auxiliary injection pipe.
[0040] In addition, the above injection pipe structure (220A, 220B) is configured to have an injection pipe arrangement structure in which a space (N) is formed in the area where the rotating central axis (P) is located, in order to secure a space where the rotating central axis (P) that crosses the center of the regeneration tank (210) is arranged.
[0041] For example, as shown in FIG. 5, when viewing the arrangement of the injection pipe structure inside the rotating central axis (P) and the regeneration tank (210) from above, the injection pipe structure (220A, 220B) is arranged vertically, and a space (N) is secured, so that the auxiliary injection pipe is removed on one side where the central axis (P) is arranged.
[0042] When such a clearance space (N) is formed, multiple injection pipes are positioned vertically in the existing injection pipe arrangement structure, taking into account only injection efficiency, which causes a problem that makes it almost impossible for repair personnel to enter the regeneration tank for maintenance of the injection pipes.
[0043] Therefore, in order to repair the regeneration tank and injection pipe structure of the existing structure, repairs were only possible by separating the entire internal injection pipe structure from the regeneration tank and repairing it from the outside; however, in the present invention, such an open space (N) is formed to ensure structural efficiency that allows a user to easily enter the interior of the regeneration tank.
[0044] Inside the regeneration tank (210) of the present invention, a regeneration carbon discharge unit (230) is arranged to efficiently process the regeneration and discharge of dry activated carbon.
[0045] The above-mentioned regenerated coal discharge unit (230) is configured to include a discharge scraper unit (S) that is axially positioned at the center of the regenerated tank (210) and rotated by being coupled to the lower part of a rotating central shaft (P) and rotating, as shown in FIG. 4.
[0046] That is, the discharge of the spent activated carbon (hereinafter referred to as "regenerated carbon") that has completed the regeneration process using the superheated steam injection unit (220) is made possible by utilizing the discharge scraper unit (S) connected to the lower part of the central rotating shaft (P) of the regeneration tank to discharge it through the pipe installed at the bottom of the regeneration tank.
[0047] As shown in FIG. 4, the central rotating shaft (P) is positioned to penetrate the center of the regeneration tank (210), is fixed through the upper fixing part (P1) of the upper part of the regeneration tank and the lower fixing part (P2) outside the regeneration tank, and is configured to enable shaft rotation by applying a worm gear (WG) through the driving of a driving motor (M1).
[0048] In this case, it is more desirable to apply a labyrinth sealing (non-contact, lubrication-free sealing) to the inner side of the upper fixed part (P1) and lower fixed part (P2) of the central rotating shaft (P) penetrating the regeneration tank so that they can be fixed for smooth rotation.
[0050] FIG. 6 is a conceptual diagram for explaining the structure of the discharge scraper unit (S) of the present invention.
[0051] The discharge scraper unit (S) positioned at the lower part of the central rotating shaft (P) can be configured to include a rotating bar (232) that rotates in conjunction with the central rotating shaft (P) as shown in FIGS. 4 and 6, and an angle-adjustable scraper member (234) that is coupled to the lower part of the rotating bar (232) to move the regenerated bullet in the direction of the central rotating shaft (P).
[0052] A regenerated bullet discharge section (242, 244), which is a discharge groove for discharging regenerated bullets, is provided at the bottom of the regenerated tank (210). A plurality of scraper members (234) having a flat blade structure are arranged on a rotating bar (232) that rotates in conjunction with the central rotation axis (P), and the arrangement angle can be implemented by adjusting the angle so that the regenerated bullets can naturally gather towards the center. As shown in FIG. 6, the angle of the outermost scraper members (f3, f4) is set so that the regenerated bullets in the wall area inside the regenerated tank are scraped and gathered inward, and the inner scraper members (f1, f2, f5, f6) can have their first angle (θ1) adjusted to an acute angle so that the regenerated bullets are sequentially moved towards the center according to rotation. In this case, the second angle (θ2) of the outermost scraper members (f3, f4) can be formed to be smaller than the first angle (θ1) so that the regenerated bullet can be efficiently collected in the center.
[0053] The recycled coal collected in the center of the recycling tank is discharged from the recycled coal discharge section (242, 244) as shown in FIGS. 4 and 6. The recycled coal discharged from the recycled coal discharge section (242, 244) is transferred to the cooling hopper (310) of the cooling treatment module (300) connected to the recycling tank (210).
[0054] After regeneration in the regeneration tank, the material is quickly discharged to the outside and cooled in an external cooling treatment module (300). At the same time, the emptied regeneration tank can be immediately put back into the regeneration process, thereby increasing process efficiency.
[0055] The difference in process time between the regeneration method using the dry regeneration facility of the present invention and the regeneration method using the existing wet regeneration facility (applying the same capacity to the activated carbon regeneration tank and the waste activated carbon introduced for regeneration) is as follows.
[0056] [Comparison Table 1]
[0057]
[0058] In the case of a regeneration method using the dry transfer regeneration facility of the present invention, if the time for transferring to the regeneration tank is reduced by 2 hours compared to wet transfer, the regeneration time is also shortened by 4 hours from the existing 24 hours to 20 hours due to the time spent waiting for drainage and the efficiency of superheated steam.
[0059] In particular, the structure is implemented such that after the regeneration process is completed, the material is discharged directly from the regeneration tank to perform external cooling, and at the same time, the regeneration tank is reused for the regeneration process. Therefore, the cooling process performed inside the regeneration tank in the existing process (natural cooling for 24 hours after regeneration is completed in the regeneration tank + forced cooling by adding cooling water for 8 hours) is eliminated.
[0060] As a result, the overall usage time of the regeneration tank (regeneration process and cooling, etc.) is reduced from 72 hours in the wet transfer regeneration process to 34 hours, resulting in a reduction of approximately 52.7% in process time and a significant improvement in process efficiency.
[0061] In addition, in the case of the present invention, 10m in the dry regeneration method 3 The amount of condensate generated during the regeneration process is 16.27 m³ 3 Compared to the existing wet regeneration method, 10m 3 The amount of condensate generated during the regeneration process is 21.27 m³ 3 As a result, the generation of condensate is significantly reduced. That is, when the dry regeneration facility according to the present invention is applied, compared to the wet regeneration method, the same amount of spent activated carbon (10 cubic meters (m) 3 Regarding )), condensate is reduced by 23.5%, which is confirmed as an advantage that significantly reduces wastewater generation.
[0062] In addition, water usage is significantly reduced when transferring activated carbon to the regeneration tank. This is because the same amount of spent activated carbon (10 cubic meters (m²) 3 Regarding )) in the case of the wet method for a single transfer and return, 20m 3 Although water is used, in this invention, 10m is used only for return discharge after regeneration. 3 Since it is used, the advantage of reducing water usage by 50% is realized.
[0063] FIG. 7 is a detailed conceptual diagram illustrating the structure of a cooling treatment module (300) that cools the recycled coal discharged from the recycling tank (210) from the outside after the recycling process is completed.
[0064] Referring to FIG. 7 and FIG. 2, the device may be configured to include a cooling hopper (310) that receives recycled coal discharged from a recycled coal discharge section (242, 244) formed at the bottom of the recycled tank (210), a cooling water supply section (W) that supplies cooling water into the interior of the cooling hopper (310), and an ejector (J) that combines the cooled recycled coal discharged from the cooling hopper (310) with process water and transports it.
[0065] In other words, unlike conventional methods, the present invention enables an increase in the operating rate of the regeneration tank by implementing a facility that separately performs cooling outside the regeneration tank, rather than carrying out a natural cooling process and cooling water cooling (forced cooling) after regeneration in the regeneration tank.
[0066] The regenerated carbon discharged outside the regeneration tank (210) by the rotational drive of the discharge scraper unit (S) is fed into the cooling hopper (310). In this case, cooling water is supplied from the cooling water supply unit (W) to the cooling hopper to rapidly cool the high-temperature regenerated carbon. The regenerated carbon in the cooling hopper (310), after cooling is complete, is mixed with process water through the ejector (J), transferred to the drain hopper (410) described later, and then the moisture contained in the activated carbon can be discharged. The cooling water supplied for cooling the regenerated activated carbon can be reused through circulation after the activated carbon is cooled.
[0067] FIG. 8 is a conceptual diagram illustrating the structure of the regenerated carbon removal module (400) from which moisture has been discharged according to the present invention.
[0068] That is, the drain hopper (410), which receives the recycled coal cooled in the cooling treatment module (300), discharges the moisture and stores it in the collection tank (Q1), and the recycled coal is transferred via the quantitative transfer conveyor (420), passes through the quantitative tank (430), is packaged into a ton bag (T), and then is discharged to the outside.
[0069] FIG. 9 is a conceptual diagram for explaining the structure and function of the exhaust combustion module (500) of the present invention.
[0070] Referring to FIG. 9 and FIG. 2, the exhaust combustion module (500) performs the function of introducing and burning to remove exhaust, including exhaust vapor discharged from the regeneration tank (210) or the cooling hopper (310).
[0071] Specifically, the exhaust combustion module (500) may be configured to include a mixing chamber (510) that collects and receives exhaust (x1, x2) including exhaust steam discharged from the regeneration tank (210) and exhaust steam (y) generated during cooling in the cooling hopper (310), an inlet section (520) that introduces the exhaust flowing in from the mixing chamber (510) into the combustion chamber (530), and a combustor (540) that combusts the exhaust flowing in from the inlet section (520) into the combustion chamber.
[0072] In the combustion process of the exhaust of the regeneration tank in FIG. 9, when the regeneration process is performed in the regeneration tank (210) illustrated in FIG. 2 and FIG. 4, the internal temperature and pressure rise excessively and rapidly compared to the conventional wet method, and the process proceeds. A relief valve (V1) for controlling the internal pressure of the regeneration tank can be formed at the top of the regeneration tank.
[0073] When the pressure of the regeneration tank is controlled through the relief valve (V1), if the internal pressure of the regeneration tank exceeds the operating pressure, the exhaust steam (x1) inside the regeneration tank is transferred to the exhaust combustion module (500) through the piping by opening the relief valve and allowing it to be combusted.
[0074] In addition, some exhaust steam and condensate (x2) generated from the activation reaction of superheated steam and dry waste activated carbon at the bottom of the regeneration tank (210) are discharged through the discharge valve (V2), and after passing through the piping, are transferred to the exhaust combustion module (500) for combustion treatment.
[0075] As illustrated in FIG. 9, the exhaust steam (x1) and the exhaust steam and condensate (x2) inside the regeneration tank are transferred to the mixing chamber (510). The exhaust steam and other substances introduced into the mixing chamber (510) are circulated and introduced by the high-temperature circulating gas (800°C) generated during the combustion reaction in the combustion chamber (530), thereby undergoing a temperature increase process. The exhaust steam (x1) and the exhaust steam and condensate (x2) inside the regeneration tank (hereinafter referred to as 'mixed discharge') that have undergone this ambient temperature process are heated to 100°C or higher when introduced into the inlet (520). When the process of introducing them into the combustion chamber (530) and being combusted by the combustor (540) is implemented, they are oxidized into a gas of 900°C or higher.
[0076] As described above, the high-temperature oxidizing gas in the combustion chamber is reintroduced into the mixing chamber as circulating gas (a3) through the valve of the circulation unit (550).
[0077] Furthermore, when forced cooling occurs rapidly in the cooling hopper (310) located at the bottom of the regeneration tank (210), the resulting exhaust vapor and oil vapor (y1) are also transferred to the exhaust combustion module (500) through the exhaust valve (V3) piping and combusted.
[0078] The exhaust combustion module (500) of the present invention described above burns and oxidizes exhausts, such as condensate or exhaust steam, that are partially generated in a dry activated carbon regeneration facility, thereby eliminating the need for a separate facility to treat excessive condensate, making the facility structure more efficient, and enabling an environmentally friendly process.
[0079] As described above, the technical concept of the present invention has been specifically described in preferred embodiments; however, the aforementioned preferred embodiments are for illustrative purposes only and are not intended to be limiting. As such, a person skilled in the art will understand that various embodiments are possible within the scope of the technical concept of the present invention through the combination of embodiments thereof.
