Description

Technical Field

[0001] The present invention relates to an integrated system of activated carbon regeneration and water treatment, and more specifically to a system capable of integrated operation of automatic activated carbon regeneration and water treatment, which is suitable for automatic waste coal discharge and regenerated carbon delivery equipment and waste coal / regenerated carbon conveying devices in large-scale water treatment activated carbon filtration systems. Technical Background

[0002] Generally speaking, sewage and wastewater treatment facilities are facilities that purify various types of sewage, such as domestic sewage or industrial wastewater, to a certain level and discharge them.

[0003] The operation mode of this sewage and wastewater treatment facility is to pass the sewage and wastewater through a water treatment tank filled with an adsorbent, and to adsorb harmful components contained in the sewage and wastewater with the adsorbent to purify it.

[0004] As an adsorbent generally filled in a water treatment tank, activated carbon is mainly used. Activated carbon is an amorphous material mostly composed of carbon, has a large specific surface area and adsorption capacity, and has excellent removal ability for harmful substances.

[0005] This activated carbon is a porous carbonaceous material used as an adsorbent for various purposes. It is not only used in the chemical industry, such as purification, removal of harmful substances, decolorization, extraction and separation, but also used to prevent environmental pollution such as air pollution, waste disposal and water pollution, and is used for tap water treatment, wastewater treatment, exhaust gas adsorption and solvent recovery, etc. The demand in various industrial fields is increasing.

[0006] The activated carbon used as an adsorbent in most industrial wastewater treatment facilities will be filled with organic matter in the pores formed on the surface of the activated carbon after a certain period of time, and the ability to purify polluted water will drop sharply, so the activated carbon needs to be replaced or regenerated regularly.

[0007] In large-scale facilities that generally treat large amounts of sewage and wastewater, the part that carries the heaviest burden in terms of cost and facility operation is the part related to activated carbon regeneration. There is a trend to ensure overall facility operation efficiency by organically combining wastewater treatment operations and activated carbon regeneration operations.

[0008] The current activated carbon regeneration method is to remove the waste carbon from the water treatment tank, transport it over a long distance off-site, regenerate it in the activated carbon regeneration equipment, transport it back to the original location and put it into the water treatment tank. The disadvantage of this activated carbon regeneration method is that the time required for a series of regeneration work is extended or the growth period is prolonged, resulting in a high cost burden and a reduced operating rate of the water treatment equipment, such as delays in the operation of the water treatment tank, and a high loss rate of activated carbon during the regeneration process, resulting in large economic losses.

[0009] Therefore, the applicant proposed a new integrated wastewater treatment system in Korean Patent No. 10-2092542, in which an automatic regenerated carbon delivery device is set between the water treatment equipment and the activated carbon regeneration equipment to automatically discharge and transport waste coal and automatically deliver regenerated carbon using air and high-pressure water.

[0010] However, although the technology of the Korean Patent No. 10-2092542 of the present applicant can construct an economical and efficient system by integrating and operating the water treatment equipment belonging to a plurality of water treatment tanks and the activated carbon regeneration equipment belonging to a plurality of activated carbon regeneration tanks, there is a limitation that the loss rate of activated carbon lost at a certain rate during the transportation of the waste activated carbon and the regenerated activated carbon cannot be completely removed. In addition, since there is no system structure for discharging condensed water generated during the activated carbon regeneration process, a treatment technology suitable for environmental protection is required.

[0011] Furthermore, in the structure of a superheated steam-forming boiler for activated carbon regeneration, there has been a demand for a new type of boiler structure that can efficiently form superheated steam, stably and reliably, and system progress has also encountered various problems.

[0012] Summary of the invention

[0013] Technical problem to be solved by the invention

[0014] The present invention is proposed to solve the problems mentioned above. The purpose of the present invention is to provide a system that adjusts the mixing ratio of water and activated carbon during the transportation process of waste coal discharged from a water treatment tank and the transportation process of regenerated carbon supplied from an activated carbon regeneration tank, and transports the mixed mixture through a hose pump unit. By applying this method, the transportation efficiency of waste coal and regenerated carbon can be improved, and the loss rate of waste coal and regenerated carbon can be minimized.

[0015] In addition, another object of the present invention is to provide a system that, by introducing post-treatment technology, can add a high-temperature reaction-type purifier to the high-temperature condensed water generated in the process of regenerating waste activated carbon using superheated steam for purification, so that the condensed water generated in the process of regenerating activated carbon using superheated steam can be purified and discharged through post-treatment, thereby constructing an environmentally friendly regeneration system and optimizing the formation of superheated steam by improving the boiler structure, thereby maximizing energy efficiency.

[0016] Technical solutions to solve problems

[0017] As a solution to the above technical problems, Figures 1 to 6As shown, an embodiment of the present invention can provide an activated carbon regeneration and water treatment integrated system, which includes: a plurality of water treatment tanks 10, which are used to use activated carbon to adsorb impurities contained in wastewater; a waste coal storage tank 11, which is used to store waste coal discharged from the water treatment tank 10; at least one activated carbon regeneration tank 100, which is used to regenerate the activated carbon supplied from the waste coal storage tank 11; and a regenerated carbon storage tank 13, which stores the regenerated carbon discharged from the activated carbon regeneration tank 12 and supplies it to the water treatment tank 10. The waste activated carbon is transported in the first process. The waste activated carbon is transported from the water treatment tank to the waste coal storage tank 11. In the second transport process, the waste activated carbon is transported from the waste coal storage tank 11 to the activated carbon regeneration tank 100. In the third transport process, the regenerated activated carbon regenerated in the activated carbon regeneration tank 100 is transported to the regenerated carbon storage tank 13. The first transport process, the second transport process, and the third transport process are realized by the transport pump unit 200. The transport pump unit 200 allows the mixed substance of water and activated carbon or waste activated carbon in a mixed state to flow into the elastic hose 230 and uses the pressure roller 250 to squeeze the elastic hose for transport.

[0018] Effects of the Invention

[0019] According to the embodiment of the present invention, the following effects are achieved: in the process of conveying waste coal discharged from a water treatment tank and in the process of conveying regenerated carbon supplied from an activated carbon regeneration tank, the mixing ratio of water and activated carbon is adjusted, and the mixture in a mixed state is conveyed through a hose pump unit. By applying this method, the conveying efficiency of waste coal and regenerated carbon can be improved, while minimizing the loss rate of waste coal and regenerated carbon.

[0020] Furthermore, by introducing post-treatment technology, a high-temperature reaction-type purifier can be added to the high-temperature condensed water generated in the process of regenerating waste activated carbon using superheated steam for purification. Thus, the condensed water generated in the process of regenerating activated carbon using superheated steam can be purified and discharged through post-treatment, thereby building an environmentally friendly regeneration system.

[0021] In particular, the condensed water generated during the regeneration of waste activated carbon using superheated steam is high-temperature wastewater. Therefore, there is no need to construct a heating device for separate reaction temperature treatment during the purification process. By adding a suitable purifier, purification can be performed during the discharge process, thereby achieving economical purification.

[0022] Furthermore, according to another embodiment of the present invention, the structure of the superheated steam generating boiler module for generating hot steam can adopt a stable structure, which can minimize the damage caused by heat while effectively generating high-temperature steam, thereby minimizing the operating time.

[0023] In addition, the present invention has the following effects: water treatment equipment belonging to multiple water treatment tanks and activated carbon regeneration equipment belonging to multiple activated carbon regeneration tanks are integrated and operated, and a new system for organic discharge and the placement of waste coal and regenerated carbon is applied between the water treatment equipment and the activated carbon regeneration equipment, thereby improving the system operation efficiency, making the system operation economical, reducing the loss rate of activated carbon, and improving the operation rate of the water treatment facilities.

[0024] In particular, a hose pump is used for transportation when the waste carbon in the water treatment tank is discharged or supplied to the regeneration tower, thereby minimizing the loss of activated carbon, and an environmentally friendly system can be built through a purification process that directly utilizes the heat carried by high-temperature condensed water for purification.

[0033] The advantages and features of the present invention and the methods for achieving them will become clear through 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 be embodied in other forms. On the contrary, the embodiments introduced herein are provided to make the disclosed content thorough and complete, and to fully convey the spirit of the present invention to those skilled in the art.

[0034] Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

[0035] Figure 1 is a top view of the layout of an integrated system for activated carbon regeneration and water treatment (hereinafter referred to as 'the present invention') according to an embodiment of the present invention, Figure 2 is a block diagram of the pipeline configuration of the activated carbon regeneration and water treatment integrated system according to one embodiment of the present invention, Figure 3 yes Figure 2 The structural concept diagram of the medium delivery pump unit. Figure 4 It is based on the activated carbon regeneration tank Figure 2 System structure diagram of the system structure in .

[0036] The integrated activated carbon regeneration and water treatment system of the present invention integrates and operates large-scale water treatment equipment to which multiple water treatment tanks belong and minimum activated carbon regeneration equipment to which multiple activated carbon regeneration tanks belong, and automatically puts in regenerated carbon while effectively discharging and transporting waste coal based on a hose pump unit between the water treatment equipment and the activated carbon regeneration equipment, thereby forming a new integrated wastewater treatment system. By integrating and operating large-scale water treatment equipment to which multiple water treatment tanks belong and minimum activated carbon regeneration equipment to which multiple activated carbon regeneration tanks belong, regenerated carbon is automatically put in while discharging and transporting waste coal with a minimized loss rate, thereby forming a new integrated wastewater treatment system.

[0037] For this purpose, refer to Figures 1 to 4 The present invention includes: a plurality of water treatment tanks 10 for adsorbing impurities contained in wastewater using activated carbon; a waste coal storage tank 11 for storing waste coal discharged from the water treatment tank 10; at least one activated carbon regeneration tank 100 for regenerating activated carbon supplied from the waste coal storage tank 11; and a regenerated carbon storage tank 13 for storing the regenerated carbon discharged from the activated carbon regeneration tank 12 and supplying it to the water treatment tank 10.

[0038] The water treatment tank 10 is a device that allows water to pass through an adsorbent filled inside, such as activated carbon, to adsorb harmful components in the wastewater with the activated carbon and then purify it before discharging it. Unlike a general water treatment tank for pure wastewater treatment without an activated carbon regeneration device, the water treatment tank 10 has a structure that can discharge and put in regenerated carbon to regenerate the activated carbon, which is advantageous not only in terms of structure but also in terms of operation efficiency.

[0039] like Figure 2 As shown, the present invention adopts the structure of the previous invention to perform the treatment function of the water treatment tank 10, but does not adopt the previous pressure tank and the applicable discharge method of high-pressure water. Instead, it adopts a delivery pump unit (200A, 200B, 200C) with a hose unit to transport waste coal or the regenerated activated carbon described later, thereby minimizing the loss of activated carbon.

[0040] That is, Figure 2 and Figure 3 As shown, in the water treatment tank 10, in the first conveying process, the waste activated carbon is conveyed from the water treatment tank to the waste coal storage tank 11, in the second conveying process, the waste activated carbon is conveyed from the waste coal storage tank 11 to the activated carbon regeneration tank 100, and in the third conveying process, the regenerated activated carbon regenerated in the activated carbon regeneration tank 100 is conveyed to the regenerated carbon storage tank 13. The first conveying process, the second conveying process, and the third conveying process are realized by the conveying pump unit 200, and the conveying pump unit 200 allows the mixed substance of water and activated carbon or waste activated carbon in a mixed state to flow into the elastic hose 230 and uses the pressure roller 250 to squeeze the elastic hose for conveying.

[0041] like Figure 4 As shown, the delivery pump unit (200: 200A, 200B, 200C) of the present invention includes: a mixing state inspection module A, which realizes the mixing ratio of water: (activated carbon or waste activated carbon) of the mixed substance in the mixed state of water and activated carbon or waste activated carbon within the standard range of 1: (1.3~2.0), and the mixing state inspection module A includes: a sensor module a1, which is used to check the state of the mixture; an adjustment module a2, which adjusts water supply and drainage according to the detection result of the sensor module a1 to achieve water supply and drainage within the standard range; an inlet 220, which is used to allow the mixed substance passing through the adjustment module a2 to flow into the elastic hose 230; a pressure roller 250, which is used to pressurize the elastic hose 230 and perform extrusion and rolling operations; a rotation drive unit 255, which is used to rotate the pressure roller 250.

[0042] That is, the conveying pump unit 200 is a device structure that replaces the previous pressure tank, and is used to forcibly convey the waste coal discharged from the water treatment tank 10 to the waste coal storage tank 11. It is installed with an elastic hose 230 with elasticity. The elastic hose and the pressure roller are rotated to make the elastic hose contact with each other and squeeze the hose. The elastic hose generates a strong suction force through compression and the restoring force that is restored. Based on this suction force, the waste coal or activated regenerated carbon can be sucked and conveyed.

[0043] Due to the strong suction and exhaust forces, this conveying method can convey a mixture of water and waste coal in the water treatment tank, as well as a mixture of regenerated activated carbon and water in the activated carbon regeneration tank.

[0044] At this time, the mixing ratio of water:(activated carbon or waste activated carbon) in the mixed state of water and activated carbon or waste activated carbon can be realized in a standard range of 1:(1.3 to 2.0).

[0045] Most preferably, the mixing ratio of water: (activated carbon or waste activated carbon) of the mixed substance in the mixed state of water and activated carbon or waste activated carbon can be achieved in a ratio of 1:1.5. Within this range, when the proportion of water is too high, the viscosity decreases and affects the suction, and when the proportion of water is too low, the viscosity of the mixture mixed with activated carbon increases, hindering the transportation and causing the activated carbon to be crushed. Therefore, the mixing state inspection module A for adjusting the mixing ratio of the water and waste coal (or activated carbon) to the above-mentioned optimal range checks the mixing ratio of the mixture flowing in in real time through the sensor module a1, and has a regulating module a2 for achieving water intake or drainage within the optimal range, so that an efficient transportation process can be controlled. As described above, by adopting a method of adjusting the mixing ratio of water and activated carbon and transporting the mixture in a mixed state through a hose pump unit, the transportation efficiency of waste coal and regenerated carbon can be improved, while minimizing the loss of waste coal and regenerated carbon.

[0046] Figure 4 yes Figure 2 Flowchart of the arrangement of the main structure of the present invention described in FIG.

[0047] The waste coal is transported from the water treatment tank 10 to the waste coal storage tank 11 by the first transport pump unit 200A, and then flows from the waste coal storage tank 11 through the inflow portion 13 of the upper portion of the activated carbon regeneration tank 100 by the second transport pump unit 200B.

[0048] The activated carbon regeneration tank 100 receives the waste activated carbon therein and washes the received waste activated carbon, or regenerates the waste activated carbon by dehydrating, drying and injecting superheated steam to the hydraulically transported waste activated carbon. Of course, the condensate purification module 300 can purify the high-temperature exhaust water generated during the regeneration process while discharging it.

[0049] In addition, the interior of the activated carbon regeneration tank 100 is provided with a plurality of superheated steam injection modules (S: S1, S2) arranged in a horizontal structure, which are combined with the lower steam distributor and the upper steam distributor of the activated carbon regeneration tank to supply steam from the upper and lower parts, which can not only improve the equipment operation rate, but also improve the activated carbon regeneration efficiency.

[0050] The superheated steam supplied to the superheated steam injection modules (S: S1 , S2 ) is formed in a superheated steam forming module 400 provided outside the activated carbon regeneration tank 100 .

[0051] The superheated steam generating module 400 of the present invention is provided with a boiler and a superheated steam generating part having a unique structure to improve the steam generating efficiency, and a detailed description is given below.

[0052] The activated carbon may be supplied with superheated steam through a plurality of superheated steam supply modules ( 120 a , 120 b , 120 c , 120 d ) having a superheated steam supply line 125 communicating with the activated carbon regeneration tank 100 .

[0053] By providing a lower injection module S2 for injecting superheated steam from the lower part to the upper part of the activated carbon regeneration tank 100 and a plurality of upper injection modules S1 for being arranged on the inner upper part of the activated carbon regeneration tank 100 and injecting superheated steam to the lower part, superheated steam can be injected to the waste activated carbon from the upper part and the lower part at the same time. In this way, the overall equipment operation efficiency and economy related to the activated carbon regeneration treatment can be improved, the equipment structure can be simplified, the manufacturing cost can be reduced, and the activated carbon regeneration efficiency can be improved.

[0054] The upper injection module S1 for injecting superheated steam in the present invention can supply the superheated steam formed by the superheated steam forming module 400 through the superheated steam supply pipeline 125, and control the supply through each superheated steam supply valve (121, 122, 123, 124, 125).

[0055] When the activated carbon regeneration process is performed by injecting superheated steam, the high-temperature exhaust water generated during the regeneration process is discharged to the outside of the activated carbon regeneration tank 100, and in the present invention, a purification process can be performed by a condensed water purification module 300 (CL) for purifying the condensed water discharged from the activated carbon regeneration tank (RT).

[0056] Figure 5 and Figure 6 A structural diagram and a conceptual diagram of a purification process performed by the condensed water purification module 300 (CL) for purifying condensed water discharged from the activated carbon regeneration tank 100.

[0057] The condensed water purification module 300 (CL) may include: a condensed water storage tank T, connected to the lower part of the activated carbon regeneration tank 100, for storing condensed water generated during the activated carbon regeneration operation; a condensed water discharge pipeline 310, for discharging condensed water from the condensed water storage tank T; a condensation heat regulating unit 320, for regulating the temperature of the discharged condensed water to a first temperature; a purifying agent supply unit 330, for adding a purifying agent to the condensed water adjusted to the first temperature; a first mixing unit 340, for mixing the condensed water with the purifying agent added; a reaction unit 350, for stagnating and stirring the condensed water mixed with the purifying agent to perform a purification reaction; and a cooling heat regulating unit 380, for regulating the discharge temperature of the second condensed water that has completed the reaction in the reaction unit 350 to a second temperature.

[0058] In addition, the condensed water purification module (CL) may also include: a neutralizer supply section 360, used to add a neutralizer to the second condensed water discharged from the reaction section 350 to induce a neutralization reaction; a second mixing section 370, used to mix the second condensed water and the neutralizer to produce a neutralization reaction; and a discharged water detection section 390, used to measure the acidity (Ph) of the second condensed water discharged through the cooling heat regulation section 380, and calculate and adjust the amount of neutralizer added by the neutralizer supply section 360.

[0059] Below, refer to Figure 5 and Figure 6 The functions of the main structures and purification process of the present invention are described.

[0060] First, the exhaust water discharged from the activated carbon regeneration tank 100 is discharged through the condensed water discharge line 310 of the present invention. In this case, it is exhaust water used in the regeneration process by superheated steam, which generally corresponds to a high temperature of 105 to 110°C.

[0061] To this end, the present invention performs temperature regulation through the condensation heat regulating unit 320 including a heat exchanger, and the heat exchanger adjusts the reaction to the optimal reaction temperature by mixing with the purifier. That is, the structure of the condensation heat regulating unit 320 can be realized as a heat exchanger structure for adjusting the temperature of high-temperature condensed water to a temperature most suitable for the oxidation reaction. Generally, the sludge treatment condensed water itself can perform the function of adjusting high-temperature hot water (above 105°C) to a high temperature (95°C) range.

[0062] Next, a liquid purifier may be supplied to the discharged water passing through the condensation heat regulating section 320. That is, the structure of the purifier supply section 330 of the present invention may be composed of a supply line capable of supplying a liquid purifier (persulfate is applicable in one embodiment of the present invention) through a separate storage tank 331, and may be realized as a structure capable of directly injecting persulfate into the piping line of the condensed water. The injected persulfate stagnates in the first mixing section 340 and is first mixed.

[0063] In particular, in the purification structure of condensed water, persulfates such as sodium persulfate can carry out the most effective purification reaction in the high temperature (95°C) range. In the present invention, the exhaust water discharged from the device system utilizing superheated steam is at high temperature, so it has the advantage of not requiring a separate heat source device such as a heating device for exhaust water.

[0064] Next, in the case of the reaction section 450, the mixed condensed water and the purifier are contained in a predetermined reaction tank at a specific temperature, and the structure is configured to be capable of carrying out a purification reaction. The liquid persulfate used as the purifier reacts with the discharged water (condensed water), and at this time, it is preferred to have a predetermined stirring function to maximize the purification reaction.

[0065] Furthermore, the present invention preferably has a neutralizer supply unit 460 to be able to adjust the acidity of the discharged water (condensed water) to be purified. To this end, in the present invention, the neutralizer supply unit allows the tank for storing the neutralizer (e.g., NaOH) to supply the neutralizer in liquid phase, so that the liquid phase neutralizer can be directly supplied through the discharge line for discharging the condensed water for the purification reaction to adjust the acidity of the discharged condensed water. In the state of being discharged by reaction with persulfate during the purification reaction, the pH is a strong acid of about 1 to 2, which can be adjusted to a neutral or weak alkaline acidity of 6 to 8 through a neutralization reaction.

[0066] In particular, the neutralizer supplied through the piping line and the condensed water are mixed in the second mixing unit 370. In addition, the amount of the neutralizer added can be automatically calculated and added by detecting the pH of the discharged water through the discharged water detection unit 390 to automatically calculate and add the amount of the neutralizer corresponding to the pH of the discharged water.

[0067] Furthermore, in the present invention, a cooling heat regulating section 380 may be provided. The condensed water after the purification reaction and the neutralization reaction has a high temperature of about 90°C. A cooling device is provided to cool the temperature to a temperature suitable for discharge, which can significantly reduce the temperature of the discharged water.

[0068] By adding a purifier to purify the high-temperature exhaust water generated in the activated carbon regeneration process, there is no need for a separate exhaust water heating device. The efficiency of the purifier can be exerted by utilizing the exhaust water temperature, thereby realizing an economical and environmentally friendly device structure.

[0069] Figure 7 Shown for forming a supply to Figure 4 The structure of the superheated steam forming module 400 of the superheated steam of the activated carbon regeneration tank 100 described in the above description.

[0070] Reference Figure 4 and Figure 7 The superheated steam performing forming module 400 of the present invention generates superheated steam and supplies the superheated steam through piping.

[0071] In particular, the superheated steam forming module 400 of the present invention forms superheated steam supplied to the superheated steam injection module S, and may include: a boiler 440, having a burner 442 arranged at the upper part of a combustion chamber 441, and including a flame-blocking net 443 arranged at the lower part of the burner; and a superheated steam forming part 450, including a steam heating pipe 451 separated by a structure surrounding the outer periphery of the flame-blocking net 443, a steam inlet pipe 452 and a steam outlet pipe 453 connected to one end and the other end of the steam heating pipe 451.

[0072] In addition, the superheated steam forming part 450 forms the steam inlet pipe at one end of the steam heating pipe 451 to communicate with the steam supply chamber 147, and forms the steam outlet pipe 453 at the other end to communicate with the superheated steam supply part 420, and connects the steam inlet pipe 452 and the steam outlet pipe 453 through the steam regulating pipe 454 to mix high-temperature steam and low-temperature steam for temperature regulation.

[0073] Reference Figures 7 to 10 , describing the function and structure of the detailed structure of the superheated steam forming module 400 of the present invention.

[0074] The boiler 440 of the superheated steam forming module 400 of the present invention has a combustion chamber 441 and a burner 442 is arranged at the center of the upper part. A flame arrester 443 is formed in the lower direction of the burner to prevent the spark of the burner 442 from spreading laterally and the flame from directly hitting the steam heating pipe 451 of the superheated steam forming part 450 described later.

[0075] A ring-shaped lower water tank 446 is formed at the lower part of the combustion chamber 441, and a plurality of water tank pipes 444 are combined at the upper part at prescribed intervals for vertically connecting the lower water tank 446 and the steam supply chamber 447. At the same time, the lower water tank 446 and the steam supply chamber 147 are connected to a water level meter 445 to confirm the amount of water inside the water tank pipe 444.

[0076] The superheated steam forming part 450 forms a superheated steam heating pipe 451 inside the water tank pipe 444 of the combustion chamber 441, so that the flame blocking net 443 is located at the upper part of the inner periphery of the superheated steam heating pipe 451, thereby inducing the flame of the combustion chamber 441 not to directly hit the superheated steam heating pipe 451. At the same time, by maximizing the heat exchange time and area in the combustion chamber, high-temperature superheated steam can be smoothly and efficiently formed.

[0077] like Fig. 9 As shown, the superheated steam heating pipe 451 can be formed into various shapes, such as a coil type or a ring type, or a hybrid of the coil type and the ring type.

[0078] Figure 8 An embodiment of the present invention is shown, showing the structure of a coil-type superheated steam heating pipe 451. The coil-type superheated steam heating pipe 451 is combined with a heat deflection prevention plate 455 on the upper and lower sides, and a plurality of spacer support members 456 are sequentially inserted into the gap between the pipes, so that the steam heating pipe 451 is supported constantly, firmly and stably. In addition, this structure can prevent heat loss and allow steam to be smoothly reheated to obtain superheated steam at a desired temperature.

[0079] Furthermore, one end of the superheated steam heating pipe 451 forms a steam inlet pipe 452 to communicate with the steam supply chamber 147, and the other end forms a steam outlet pipe 453 to discharge high-temperature steam. In addition, the steam outlet pipe 453 and the main steam supply pipe 421 of the superheated steam supply unit 420 are connected to the steam supply pipe 457, and the high-temperature steam is smoothly supplied to the inside of the activated carbon regeneration tank and sprayed.
