일반적으로, 활성탄은 탄소로 구성된 무정형의 다공성 물질로 비표면적과 흡착능력이 크기 때문에 다양한 목적을 위해 흡착제로서 사용되고 있고, 정제, 유해물질 제거, 탈색, 추출 분리 등 화학공업 분야에서 이용될 뿐만 아니라, 상수처리, 폐수처리, 배기가스 흡착 및 용제회수 등에 이용되고 있어 그 수요가 지속적으로 증가되고 있는 추세이다.In general, activated carbon is an amorphous porous material composed of carbon, which is used as an adsorbent for various purposes because of its large specific surface area and adsorption capacity, and is not only used in the chemical industry, such as purification, removal of harmful substances, decolorization, extraction separation, As it is used for water treatment, wastewater treatment, exhaust gas adsorption and solvent recovery, the demand is continuously increasing.
특히 건전지와 같은 곳에도 활성탄이 사용되고 있는데, 다 쓴 건전지를 폐기할 경우에는 환경을 위하여 건전지 내부에 포함되어 있던 각종 폐기물을 먼저 처리해야 하는데, 이때 건전지 내부에 있던 활성탄은 D2EPHA, PC88A, Kerosene 등과 같은 다양한 유기용매를 흡착하고 있다. In particular, activated carbon is used in places such as batteries, and when the used battery is disposed, various wastes contained in the battery have to be disposed first for the environment.In this case, activated carbon inside the battery is treated with D2EPHA, PC88A, Kerosene, etc. Various organic solvents are adsorbed.
따라서, 폐건전지의 처리와 활성탄의 재활용을 위해서는 D2EPHA, PC88A, Kerosene 등과 같은 유기용매를 제거해야 하는데, 아직까지는 적절한 장치가 제시되고 있지 않다.Therefore, organic solvents such as D2EPHA, PC88A, Kerosene, etc. have to be removed for the treatment of waste batteries and the recycling of activated carbon.
본 발명은 상기한 종래기술의 문제점을 해결하기 위하여 안출된 것으로서, 활성탄이 흡착하고 있는 D2EPHA, PC88A, Kerosene 등과 같은 유기용매를 효율적으로 제거하여 활성탄을 재활용할 수 있도록 하는 활성탄 재생장치를 제공하는데 그 목적이 있다.The present invention has been made to solve the above-mentioned problems of the prior art, and provides an activated carbon regeneration apparatus to efficiently recycle the activated carbon by removing organic solvents such as D2EPHA, PC88A, Kerosene, etc. adsorbed by the activated carbon. There is a purpose.

A conveying unit made of a motor to make; An electric furnace installed to enclose an outer surface of the transfer pipe to heat and vaporize a residual solvent adsorbed on activated carbon; And a hood installed at an upper portion of the hopper to generate a suction force to suck gas vaporized by the electric furnace.
여기서, 상기 전기로는 상기 이송관의 외측면을 둘러싸고 발열을 하는 전열선과; 상기 전열선과 이송관의 외측면을 둘러싸는 단열재와; 상기 단열재를 내부에 수용하는 케이싱;을 포함하여 구성된다.Here, the electric furnace and the heating wire for generating heat surrounding the outer surface of the transfer pipe; Insulation material surrounding the outer surface of the heating wire and the transfer pipe; It is configured to include; casing for accommodating the heat insulating material therein.
그리고, 상기 전열선은 상기 단열재의 중간 부분에 설치되어, 전열선을 중심으로 양측에 위치한 단열재는 상기 이송관의 외측면에 직접 접촉된다.In addition, the heating wire is installed in the middle portion of the heat insulating material, the heat insulating material located on both sides of the heating wire is in direct contact with the outer surface of the transfer pipe.
또한, 상기 이송관에는 배출구 쪽으로 안내되는 활성탄에 산소가 접하는 것을 차단하기 위하여 질소를 주입하는 질소주입구가 구비된다.In addition, the transfer pipe is provided with a nitrogen inlet for injecting nitrogen to block the contact of oxygen to the activated carbon guided toward the outlet.
또한, 상기 배출구에는 활성탄을 회수하는 회수통이 설치되되, 상기 회수통은 밀폐되어 외부의 공기가 차단된다.In addition, the discharge port is provided with a recovery container for recovering activated carbon, the recovery container is sealed to block the outside air.
상기와 같이 구성되는 본 발명의 활성탄 재생장치는 활성탄이 흡착하고 있던 유기용매가 전기로에 의해 가열되어 가스화되고, 이 고온의 가스가 호퍼쪽으로 이동하면서 후속하는 활성탄을 가열하므로, 전기로에 가해지는 부하를 줄일 수 있는 이점이 있다.In the activated carbon regeneration apparatus of the present invention configured as described above, the organic solvent adsorbed by the activated carbon is heated and gasified by an electric furnace, and this hot gas is heated toward the hopper, thereby heating the subsequent activated carbon.

또한, 전열선을 전원을 공급하여 500℃ 정도로 가열하면 활성탄이 흡착하고 있던 D2EPHA, PC88A, Kerosene 등과 같은 유기용매를 효율적으로 제거할 수 있는 이점이 있다.In addition, when the heating wire is supplied with a power source and heated to about 500 ° C., there is an advantage in that organic solvents such as D2EPHA, PC88A, Kerosene, and the like which have been adsorbed by activated carbon can be efficiently removed.
또한, 전열선을 단열재 내측면의 전면적에 걸쳐 설치하지 않고 단열재의 중간 부분에만 설치하기 때문에 전열선을 거쳐 배출구 쪽으로 가는 활성탄은 배출구까지 이송되는 동안 냉각이 되어 회수통에 모일 때는 공기와 접하더라도 산화될 가능성이 낮아지는 이점이 있다.In addition, since the heating wire is not installed over the entire inner surface of the insulating material, but only at the middle part of the insulating material, activated carbon that passes through the heating wire toward the discharge port is cooled while being transported to the discharge port and oxidized even when contacted with air when gathered in the collecting container. This has the advantage of being lowered.
또한, 질소주입구를 통하여 이송관 내부로 공급되는 질소가스에 의하여 활성탄이 공기와 접하여 산화되는 것을 방지할 수 있는 이점이 있다.In addition, there is an advantage that the activated carbon is prevented from being oxidized in contact with the air by the nitrogen gas supplied into the transfer pipe through the nitrogen inlet.

상기 호퍼(111)는 이송관(110)의 일측 끝부분에 구비되는 것으로서, 상측에 설치된 진동피더(500)로부터 잔류 유기용매를 흡착하고 있는 활성탄(C)을 제공받는다. 이러한 호퍼(111)는 이송관(110)의 내부 공간과 연통되어 호퍼(111)를 통해 공급된 활성탄(C)은 이송관(110) 내부로 공급된다.The hopper 111 is provided at one end of the transfer pipe 110 and is provided with activated carbon (C) adsorbing the residual organic solvent from the vibration feeder 500 installed on the upper side. The hopper 111 is in communication with the interior space of the transfer pipe 110, the activated carbon (C) supplied through the hopper 111 is supplied into the transfer pipe (110).
상기 배출구(112)는 상기 호퍼(111)의 반대쪽 끝부분에 설치되는 것으로서 잔류 유기용매가 제거된 활성탄(C)을 이송관(110) 외부로 배출시킨다.The outlet 112 is installed at the opposite end of the hopper 111 to discharge the activated carbon (C) from which the residual organic solvent is removed to the outside of the transport pipe (110).
한편, 상기 이송관(110)에는 질소주입구(113)가 구비된다.On the other hand, the transfer pipe 110 is provided with a nitrogen inlet 113.
상기 질소주입구(113)는 상기 배출구(112)가 설치된 쪽에 설치되어 배출구(112) 쪽으로 안내되는 활성탄(C)에 공기가 접하는 것을 차단하기 위하여 질소를 주입할 때 사용한다. 전기로(200)에서 가열되어 나온 활성탄(C)은 고온의 상태가 유지되기 때문에 공기와 접했을 때 산화되어 손실될 위험이 있다. 바로 이러한 위험, 즉 공기와 고온의 활성탄(C)이 접촉되어 활성탄(C)이 손실되는 것을 방지하기 위하여 활성탄(C) 주위를 질소로 충진한다.The nitrogen inlet 113 is used to inject nitrogen to block the contact of air to the activated carbon (C) guided toward the outlet 112 is installed on the side where the outlet 112 is installed. Activated carbon (C) heated in the electric furnace 200 is maintained in a high temperature state there is a risk of being oxidized and lost when contacted with air. In order to prevent this risk, that is, contact of air with high temperature activated carbon (C) and loss of activated carbon (C) is filled with nitrogen around the activated carbon (C).
상기 이송스크류(120)는 상기 이송관(110) 내부에 회전가능하게 설치되는 것으로서, 샤프트(121)와, 상기 샤프트(121)의 외측면에 설치된 이송날개(122)로 구성된다.The conveying screw 120 is rotatably installed in the conveying pipe 110, it is composed of a shaft 121, the conveying blade 122 is installed on the outer surface of the shaft 121.
상기 샤프트(121)는 상기 이송관(110)의 길이방향을 따라 이송관(110) 내부 중앙에 수평방향으로 길게 설치되고, 양단이 베어링 등을 이용하여 이송관(110) 내부에 회전가능하게 설치된다.The shaft 121 is installed in the horizontal direction in the center of the transfer pipe 110 in the longitudinal direction along the longitudinal direction of the transfer pipe 110, both ends rotatably installed in the transfer pipe 110 using a bearing or the like. do.
상기 이송날개(122)는 상기 샤프트(121)의 외측면에 나선형태로 설치되어 샤프트(121)가 회전할 때 이송날개(122)가 함께 회전하면서 활성탄(C)을 배출구(112) 쪽으로 밀어낸다.The transfer blade 122 is installed in a spiral shape on the outer surface of the shaft 121 to push the activated carbon (C) toward the outlet 112 as the feed blade 122 rotates together when the shaft 121 rotates. .
상기 모터(130)는 모터축이 상기 이송스크류(120)의 샤프트(121)와 동력적으로 연결되어 모터축의 회전력이 그대로 이송스크류(120)에 전달된다. 따라서, 상기 모터(130)에 전원이 공급되어 모터축이 회전하면 이송스크류(120)가 회전되어 활성탄(C)이 배출구(112) 쪽으로 이송된다.The motor 130 has a motor shaft is dynamically connected to the shaft 121 of the transfer screw 120 so that the rotational force of the motor shaft is transmitted to the transfer screw 120 as it is. Therefore, when power is supplied to the motor 130 and the motor shaft rotates, the transfer screw 120 is rotated so that the activated carbon C is transferred toward the outlet 112.
상기 전기로(200)는 상기 이송관(110)의 외측면을 둘러싸도록 설치되는 것으로서, 전기로(200)에서 발생된 열에 의하여 활성탄(C)에 흡착되어 있는 잔류 유기용매가 가열되어 기화된다.The electric furnace 200 is installed to surround the outer surface of the transfer pipe 110, the residual organic solvent adsorbed on the activated carbon (C) by the heat generated in the electric furnace 200 is heated and vaporized.
이와 같은 전기로(200)는 전열선(210)과, 단열재(220) 및 케이싱(230)을 포함하여 구성된다.The electric furnace 200 is configured to include a heating wire 210, the heat insulating material 220 and the casing 230.
상기 전열선(210)은 상기 이송관(110)의 외측면을 둘러싸는 것으로서, 전원이 공급되었을 때 발열을 함으로써 상기 이송관(110) 내부를 가열하여 활성탄(C)에 흡착되어 있는 잔류용매를 가열하여 기화시킨다. 이러한 전열선(210)은 이송관(110)의 외측면 전체를 둘러싸는 것은 아니고, 이송관(110)의 중간 일부분만 둘러쌈으로써 활성탄(C)이 이송관(110) 내부를 유동하다가 전열선(210)이 감겨 있는 곳에서만 고온의 열로 가열될 수 있도록 한다.The heating wire 210 surrounds the outer surface of the transfer pipe 110 and generates heat when power is supplied to heat the transfer pipe 110 to heat the residual solvent adsorbed on the activated carbon C. To vaporize. The heating wire 210 does not surround the entire outer surface of the transfer pipe 110, but only the middle portion of the transfer pipe 110 activated carbon (C) flows through the transfer pipe 110 inside the heating wire 210 ) Can be heated by high temperature heat only where it is wound.
그리고, D2EPHA, PC88A, Kerosene 등과 같은 유기용매를 가열하여 기화시키기 위해서는 전열선(210)에 의한 발열을 500℃ 내외로 하는 것이 바람직하다. 왜냐하면 앞서 기재한 것처럼 상기와 같은 유기용매들은 그 끓는점이 500℃ 이하이기 때문이다. 필요이상으로 고온으로 가열할 경우에는 많은 에너지가 소비되어 비용이 많이 들기 때문에 효율적이지 못하다.In order to heat and vaporize an organic solvent such as D2EPHA, PC88A, Kerosene, or the like, it is preferable that the heat generated by the heating wire 210 be about 500 ° C. This is because the organic solvents described above have a boiling point of 500 ° C. or lower. Heating to a higher temperature than necessary is not efficient because much energy is consumed and expensive.
상기 단열재(220)는 상기 전열선(210)과 이송관(110)의 외측면을 둘러싼다. 따라서, 전열선(210)에서 발생된 열은 외부로 새어 나가지 않고 그대로 이송관(110) 내부로 전달되어 활성탄(C)을 가열하게 된다.The heat insulator 220 surrounds the outer surfaces of the heating wire 210 and the transfer pipe 110. Therefore, the heat generated from the heating wire 210 is transferred to the inside of the transfer pipe 110 without leaking to the outside to heat the activated carbon (C).
한편, 상기 단열재(220) 내측면에 전열선(210)이 설치될 때 상기 전열선(210)은 단열재(220)의 중간 부분에 설치된다. 즉 단열재(220)의 내측면 전체에 걸쳐서 설치되는 것이 아니고, 단열재(220)의 중간 부분에만 설치되는 것이다. 따라서, 전열선(210)을 중심으로 양측에 위치한 단열재(220)는 상기 이송관(110)의 외측면에 직접 접촉하게 된다.On the other hand, when the heating wire 210 is installed on the inner surface of the heat insulating material 220, the heating wire 210 is installed in the middle portion of the heat insulating material 220. That is, it is not installed over the entire inner surface of the heat insulator 220, but only in the middle portion of the heat insulator 220. Therefore, the heat insulating material 220 located on both sides of the heating wire 210 is in direct contact with the outer surface of the transfer pipe 110.
상기 케이싱(230)은 상기 단열재(220)와 전열선(210)을 내부에 수용한다.The casing 230 accommodates the heat insulating material 220 and the heating wire 210 therein.
상기 후드(300)는 상기 호퍼(111)의 상부에 설치되어 흡입력을 발생시킴으로써 전기로(200)에 의해 기화된 가스를 흡입한다.The hood 300 is installed on the hopper 111 to generate a suction force to suck the gas vaporized by the electric furnace 200.
상기 이송스크류(120)의 회전에 의하여 이송관(110) 내부에서 움직이는 활성탄(C)은 전기로(200)의 전열선(210)이 설치된 부분에서 고온의 열에 의해 가열된다. 이렇게 고온의 열에 의하여 가열이 되면 활성탄(C)에 흡착되어 있던 D2EPHA, PC88A, Kerosene 등과 같은 유기용매는 기화되어 가스화된다. The activated carbon C moving inside the transfer pipe 110 by the rotation of the transfer screw 120 is heated by a high temperature heat in a portion in which the heating wire 210 of the electric furnace 200 is installed. When heated by high temperature heat, organic solvents such as D2EPHA, PC88A, Kerosene, etc. adsorbed on activated carbon (C) are vaporized and gasified.
이렇게 기화되어 생성된 가스는 상기 후드(300)의 흡입력에 의해 호퍼(111) 쪽으로 이동하게 되고 결국 후드(300)를 통하여 외부로 배출된다. 이러한 노선으로 이동하는 가스는 상기 이송관(110) 내부에 있는 동안 고온의 상태를 유지하기 때문에 이송스크류(120)에 의해 전열선(210) 쪽으로 이동하는 활성탄(C)을 가열하게 된다. 즉 전열선(210)의 일측 끝부분과 호퍼(111) 사이의 공간은 일종의 예비가열 구간이 되어 전열선(210)에 의해 가열되기 전에 고온의 가스가 활성탄(C)을 미리 예열시킨다. 이렇게 하면 활성탄(C)을 가열하기 위하여 전열선(210)에 가해지는 부하가 줄어드는 이점이 있다.The gas generated in this way is moved toward the hopper 111 by the suction force of the hood 300 and is eventually discharged to the outside through the hood 300. Since the gas moving in this line maintains a high temperature while being inside the transfer pipe 110, the activated carbon C moving toward the heating wire 210 is heated by the transfer screw 120. That is, the space between one end of the heating wire 210 and the hopper 111 becomes a kind of preheating section, and the hot gas preheats the activated carbon before heating by the heating wire 210. This has the advantage of reducing the load on the heating wire 210 to heat the activated carbon (C).
상기 회수통(400)은 상기 배출구(112)에 설치되어 배출구(112)를 통해 나오는 활성탄(C)을 회수한다.The recovery container 400 is installed in the discharge port 112 to recover the activated carbon (C) coming through the discharge port 112.
이러한 회수통(400)은 밀폐되어 외부의 공기가 유입되는 것을 차단한다. 즉, 회수통(400)은 배출구(112)와 연결되는 부분만 연통될 수 있도록 하고, 그 외 나머지 부분은 외부와 격리시킨다. 이렇게 하는 이유는 회수통(400)에 회수되는 활성탄(C)은 아직까지 고온이기 때문에 공기와 접했을 때 산화될 가능성이 있기 때문이다.The recovery container 400 is sealed to block the inflow of outside air. That is, the recovery container 400 may be in communication with only the portion connected to the outlet 112, and the other part is isolated from the outside. The reason for doing this is because activated carbon (C) recovered in the recovery container 400 is still at a high temperature, which may be oxidized when it comes into contact with air.
그리고, 회수통(400)의 일측면에는 회수된 활성탄(C)을 빼내기 위한 도어(410)가 설치되어 있다.And, one side of the recovery container 400 is provided with a door 410 for taking out the recovered activated carbon (C).
상기와 같이 구성된 본 발명에 의한 활성탄 재생장치의 작동 과정에 대하여 간단히 설명하도록 한다.The operation process of the activated carbon regeneration device according to the present invention configured as described above will be briefly described.
진동피더(500)를 통하여 D2EPHA, PC88A, Kerosene 등과 같은 유기용매를 흡착하고 있는 활성탄(C)이 호퍼(111)로 공급되고, 호퍼(111)로 공급된 활성탄(C)은 이송관(110) 내부로 유입된다.Activated carbon (C) adsorbing organic solvents such as D2EPHA, PC88A, Kerosene, etc. is supplied to the hopper 111 through the vibrating feeder 500, and activated carbon (C) supplied to the hopper 111 is a transfer pipe 110. Flows inside.
모터(130)에 전원이 공급되어 모터축이 회전하면 이송스크류(120)가 회전하면서 이송날개(122)에 의해 활성탄(C)이 배출구(112) 쪽을 향하여 이송된다.When power is supplied to the motor 130 and the motor shaft rotates, the transfer screw 120 rotates so that the activated carbon C is transferred toward the outlet 112 by the transfer blade 122.
상기 배출구(112) 쪽으로 이송되던 활성탄(C)은 전열선(210)이 설치된 부분에 이르러 고온의 열로 가열된다. 이렇게 고온의 열로 가열이 되면 활성탄(C)이 흡착하고 있던 D2EPHA, PC88A, Kerosene 등과 같은 유기용매는 기화되어 기체가 된다.Activated carbon (C) was transferred toward the outlet 112 is heated to a high temperature heat to reach the portion where the heating wire 210 is installed. In this way, when heated by high temperature heat, organic solvents such as D2EPHA, PC88A, Kerosene, etc., to which activated carbon (C) has been adsorbed, are vaporized into gas.
한편, 상기와 같은 작동이 되는 동안에 후드(300)도 동작을 하고 있어서 흡입력을 발생시키고 있는데, 이때 이 후드(300)의 흡입력에 의하여 기화된 기체가 후드(300)에 흡입된다. 즉 전열선(210)에 의해 가열됨으로써 생성된 기체는 이송관(110) 내부를 유동하여 호퍼(111)를 거친 후 후드(300)로 빠져나가는데, 이렇게 빠져나가는 고온의 기체에 의하여 후속하는 활성탄(C)이 예비 가열된다. 전열선(210)의 일측 끝단에서부터 호퍼(111)까지의 구간이 일종의 예비가열구간이 되는 것이다.On the other hand, the hood 300 is also operating during the operation as described above to generate a suction force, at this time the gas vaporized by the suction force of the hood 300 is sucked into the hood 300. That is, the gas generated by heating by the heating wire 210 flows through the transfer pipe 110 and passes through the hopper 111 and then exits to the hood 300. ) Is preheated. The section from one end of the heating wire 210 to the hopper 111 is a kind of preheating section.
그리고, 전열선(210)에 의해 가열됨으로써 유기용매가 제거된 활성탄(C)은 계속 배출구(112) 쪽으로 이송된다. 이러한 이송과정에서 활성탄(C)은 냉각이 된다. 즉 전열선(210)의 타측 끝부분부터 배출구(112)까지의 구간은 일종의 서냉구간이 되는 것이다. 이 서냉구간을 거치면서 냉각된 활성탄(C)은 아무리 냉각이 되었다 하더라도 상당히 높은 온도를 유지하고 있기 때문에 혹시라도 공기와 접했을 때 산화가 될 가능성이 있다.Then, the activated carbon (C) from which the organic solvent is removed by being heated by the heating wire 210 is continuously transferred to the outlet 112. Activated carbon (C) is cooled in this transfer process. That is, the section from the other end of the heating wire 210 to the outlet 112 is a kind of slow cooling section. The activated carbon (C) cooled through this slow cooling section maintains a very high temperature no matter how much it is cooled, so it may be oxidized when in contact with air.
이러한 활성탄(C)의 산화가능성을 제거하기 위하여 상황에 따라 질소주입구(113)를 통하여 질소가스를 주입함으로써 활성탄(C)이 공기와 접하는 것을 막는다.In order to remove the oxidation potential of the activated carbon (C) in accordance with the situation by injecting nitrogen gas through the nitrogen inlet 113 to prevent the activated carbon (C) in contact with the air.
질소가스에 의하여 공기와의 접촉이 차단된 활성탄(C)은 배출구(112)를 통하여 회수통(400)에 모인다.Activated carbon (C) blocked contact with air by nitrogen gas is collected in the recovery container 400 through the outlet 112.
본 발명은 활성탄 재생장치에 관한 것으로서, 자원을 효율적으로 재활용하기 위한 환경산업 및 재활용 산업에 이용될 수 있다.The present invention relates to an activated carbon regeneration device, and can be used in an environmental industry and a recycling industry for efficiently recycling resources.
