본 발명은 유기용제함유폐수 처리 및 유기용제 회수장치에 관한 것으로서, 더욱 상세하게는, 수용성 유기용제가 녹아있는 유기용제함유폐수에 비수용성이면서 친유성인 촉매유를 혼합시켜 혼합 유기용제함유폐수로 만든 후, 부상 또는 침강 방법으로 수용성 유기용제와 촉매유가 혼합된 혼합 유기용제를 폐수와 분리하여 회수하고 폐수는 정화시켜 용수로 재사용하며, 회수된 혼합 유기용제는 증류기에서 증발, 냉각, 응축시키는 방법으로 수용성 유기용제만 회수하고, 남은 촉매유는 다시 유기용제함유폐수 처리에 재사용 할 수 있도록 하는 유기용제함유폐수 처리 및 유기용제 회수장치에 관한 것이다.The present invention relates to an organic solvent-containing wastewater treatment and organic solvent recovery apparatus, and more particularly, to a mixed organic solvent-containing wastewater by mixing a non-aqueous and lipophilic catalyst oil with organic solvent-containing wastewater in which a water-soluble organic solvent is dissolved. After making, the mixed organic solvent mixed with the water-soluble organic solvent and catalyst oil is collected by flotation or sedimentation by separating and recovering the waste water, and the waste water is purified and reused as water, and the recovered mixed organic solvent is evaporated, cooled, and condensed in a still. It relates to an organic solvent-containing wastewater treatment and organic solvent recovery apparatus that recovers only a water-soluble organic solvent and allows the remaining catalyst oil to be reused for treatment of organic solvent-containing wastewater.

테이프 제조공정, 도장 공정, 섬유제조공정, 유기용제 제조공정 등에는 여러 종류의 유기용제를 혼합하여 사용하고 있는데 사용되어지는 유기용제는 원료물질을 녹이거나 오염물질을 세척하는 등의 용매로 사용되어진 후 대부분 회수되지 않고 휘발성 유기화합물(VOCs) 형태로 휘발되어 대기로 배출되거나, 오염물질 세척수에 수용되면서 유기용제함유폐수가 되어 환경오염을 유발하는 원인이 된다.Various types of organic solvents are mixed and used in the tape manufacturing process, painting process, textile manufacturing process, and organic solvent manufacturing process. The organic solvent used is used as a solvent such as dissolving raw materials or washing pollutants. Afterwards, most of them are not recovered, but are volatilized in the form of volatile organic compounds (VOCs) and are discharged to the atmosphere, or they become wastewater containing organic solvents as they are received in the pollutant washing water, causing environmental pollution.

이러한 환경오염문제를 해소하기 위하여 대기 중으로 배출되는 VOCs 물질은 활성탄과 같은 흡착제로 흡착 처리하거나 고온에서 산화시켜 무해화한 후 대기로 배출하고, 폐수에 수용된 유기용제함유폐수는 다량의 공기를 불어넣어 폐수 내에 함유되어 있는 유기용제를 대기 중으로 휘발시켜 상기의 VOCs 물질 처리방법과 동일한 방법으로 처리하거나, 전기분해조에서 전기로 분해하여 무해 화 처리하거나, 미생물을 유기용제함유폐수에 투입하여 미생물이 폐수에 함유된 유기용제를 분해하여 처리하는 등의 다양한 기술이 개발되어 사용되어지고 있다.In order to solve this environmental pollution problem, VOCs discharged into the atmosphere are adsorbed with an adsorbent such as activated carbon or oxidized at high temperature to be detoxified, and then discharged to the atmosphere. The organic solvent-containing wastewater contained in the wastewater is blown in a large amount of air. The organic solvent contained in the wastewater is volatilized into the atmosphere and treated in the same way as the above VOCs treatment method, or detoxified by decomposing it with electricity in an electrolysis tank, or by putting microorganisms into the wastewater containing organic solvents, Various technologies have been developed and used, such as decomposing and treating organic solvents contained in

유기용제 중에 비수용성 유기용제는 물에 혼합되어도 물에 수용되지 않아서 유기용제의 비중에 따라 물위로 부상하거나 물속에서 침강되어 물과 명확한 층 분리가 일어나서 일반적인 유수 분리기술로 쉽게 회수가 되지만, 수용성 유기용제는 물과 혼합되면 물에 녹아서 유기용제함유 폐수가 되고, 녹아있는 유기용제가 물과 분리되지 않아 유기용제만을 회수하는 것은 어렵게 된다.In organic solvents, non-aqueous organic solvents are not soluble in water even if they are mixed with water, so depending on the specific gravity of the organic solvents, they float on the water or settle in water, resulting in clear layer separation from water, which can be easily recovered by general oil-water separation techniques. When a solvent is mixed with water, it dissolves in water and becomes wastewater containing an organic solvent, and since the dissolved organic solvent is not separated from water, it is difficult to recover only the organic solvent.

물에 잘 수용되는 대표적인 수용성 유기용제로는 EA(에틸 아세테이트),IPA(이소프로필 알콜), MEK(메틸에틸케톤), 메탄올, 알코올 등이 있으며 이들 유기용제는 물에 잘 수용되는 성질이 있어서 물과 혼합되면 쉽게 유기용제함유폐수가 되며 일단 유기용제함유폐수가 되면 단순한 유수분리 기술로는 유기용제를 분리 회수할 수가 없게 된다.Representative water-soluble organic solvents that are well soluble in water include EA (ethyl acetate), IPA (isopropyl alcohol), MEK (methyl ethyl ketone), methanol, and alcohol, and these organic solvents are well soluble in water. When mixed with the organic solvent-containing wastewater, once the organic solvent-containing wastewater becomes wastewater, the organic solvent cannot be separated and recovered with a simple oil-water separation technique.

한편 유기용제 중에 벤젠, 톨루엔 등과 같은 비수용성 유기용제는 물에 섞여도 물에 수용되지 않고 물과 경계면이 생기는 층 분리가 일어나서 시간이 지나면 비중 차에 의해서 물위로 뜨거나 물밑으로 가라앉아서 단순한 유수분리 기술로 쉽게 분리 회수하는 것이 가능하다.On the other hand, non-aqueous organic solvents such as benzene, toluene, etc., among organic solvents, are not absorbed in water even if they are mixed with water, and a layer separation occurs that creates an interface with water. It is possible to separate and recover easily by technology.

그러나 상기 벤젠과 같은 비수용성 유기용제는 친유성이지 않아서 쉽게 수용성 유기용제와 혼합되지 않는 특징이 있다.However, since the non-aqueous organic solvent such as benzene is not lipophilic, it is not easily mixed with the water-soluble organic solvent.

일반적으로 석유계통이라고 하는 등유나 경유, 벙커유 등과 같은 오일류는 물과 혼합되지 않는 비수용이면서 수용성 유기용제와 쉽게 혼합되는 친유성이어서 유기용제함유 폐수에서 수용성 유기용제를 회수할 때 촉매유로 사용할 수도 있다.Oils such as kerosene, diesel, and bunker oil, which are generally referred to as petroleum, are non-aqueous, which are not mixed with water, and are lipophilic, which are easily mixed with water-soluble organic solvents, so they can be used as catalyst oil when recovering water-soluble organic solvents from wastewater containing organic solvents. .

유기용제함유폐수에서 유기용제를 회수하는 방법은 유기용제함유폐수에 비수용성이고 친유성인 촉매유를 주입한 후 일정시간 혼합하면 혼합 유기용제함유폐수가 되는데 상기 혼합 유기용제함유폐수 내에서는 비수용성인 촉매유가 수용성 유기용제와 결합하여 비수용성 혼합 유기용제가 되면서 폐수와 층 분리가 일어나서 간단한 유수분리 장치로도 혼합 유기용제와 폐수로 쉽게 분리할 수 있게 된다.The method of recovering the organic solvent from the organic solvent-containing wastewater is to inject a non-aqueous and lipophilic catalyst oil into the organic solvent-containing wastewater and mix it for a certain period of time to obtain a mixed organic solvent-containing wastewater, which is non-aqueous in the mixed organic solvent-containing wastewater. As the catalyst oil combines with the water-soluble organic solvent to become a non-aqueous mixed organic solvent, wastewater and layer separation occur, so that even a simple oil-water separation device can be easily separated into a mixed organic solvent and wastewater.

한편, 대부분의 촉매유는 수용성 유기용제에 비하여 비등점이 높은 특성이 있는데 이를 이용하여 혼합 유기용제를 낮은 온도에서 증류시키면 비등점이 낮은 수용성 유기용제는 쉽게 휘발되고 촉매유는 남게 되는데, 휘발된 수용성 유기용제는 냉각, 응축시켜 원료로 회수하고 남은 촉매유는 다시 수용성 유기용제를 회수하는데 재사용 할 수가 있게 된다.On the other hand, most catalyst oils have a higher boiling point than water-soluble organic solvents.If the mixed organic solvent is distilled at a low temperature using this, the water-soluble organic solvent with a low boiling point is easily volatilized and the catalyst oil remains. The solvent is cooled and condensed to be recovered as a raw material, and the remaining catalyst oil can be reused to recover the water-soluble organic solvent again.

또한, 수용성 유기용제가 제거되고 남은 폐수는 소량의 잔존하는 수용성 유기용제가 있을 수 있으므로 물에 공기를 불어넣어 잔존하는 유기용제를 휘발시키면 폐수는 처리되어 용수로 재사용하는 것이 가능하다 .In addition, since the wastewater remaining after the water-soluble organic solvent is removed may contain a small amount of remaining water-soluble organic solvent, the wastewater can be treated and reused as water by blowing air into the water to volatilize the remaining organic solvent.

상기 촉매유를 이용하여 수용성 유기용제를 회수하는 방법으로는 혼합공정, 유수 분리공정, 증류 회수공정이 필수적으로 필요한데 각 단위 공정별로는 효율이 좋은 많은 기술이 개시되어 있지만 이들 단위 공정기술은 각각 다른 용도에 맞도록 개발된 기술이어서 이들 단위 공정기술을 단순하게 조합하여 수용성 용존 유기용제 분리 및 회수장치로 사용하면 장치구성이 복잡해지고, 공사비가 높고, 운영유지 관리가 어려운 단점이 있다.Mixing process, oil-water separation process, and distillation recovery process are essential as a method of recovering a water-soluble organic solvent using the catalyst oil. Although many technologies with good efficiency have been disclosed for each unit process, these unit process technologies have different uses. Since it is a technology developed to meet the needs, if these unit process technologies are simply combined and used as a water-soluble dissolved organic solvent separation and recovery device, the device configuration becomes complicated, construction cost is high, and operation maintenance is difficult.

예를 들어서 혼합공정에 사용되는 혼합장치로는 혼합탱크에 혼합할 여러 종류의 물질을 넣고 교반기를 이용하여 교반하여 혼합하는 교반혼합방식이 있고, 교반혼합방식으로 혼합력이 약할 경우에는 교반혼합탱크로 혼합물을 투입하기 전에 라인믹서로 1차 혼합시킨 후 2차로 교반혼합탱크에서 다시 혼합하는 기술이 개시되고 있으나 교반기로만 혼합하는 방법은 교반기 날개의 회전 특성상 좌우 회전 교반만 되고 상하 교반은 잘 안 되는 문제점이 있고 교반할 물질량이 많으면 혼합탱크 직경이 커지고 되고 교반기 날개도 커지게 되어 교반기 가동에 따른 동력비가 증가되는 단점이 있으며 라인믹서를 사용하는 경우도 혼합력은 다소 높아지지만 공정이 복잡해지는 공사비 및 운영유지 관리비가 증가하는 단점이 있다.For example, as a mixing device used in the mixing process, there is a stirring and mixing method in which various kinds of substances to be mixed are put in a mixing tank, and agitated by using a stirrer, and when the mixing power is weak, the stirring mixing tank Prior to the input of the furnace mixture, first mixing with a line mixer and then secondly mixing in a stirring mixing tank has been disclosed, but the method of mixing only with a stirrer is only left and right rotation due to the rotational characteristics of the stirrer blades, and vertical agitation is difficult. If there is a problem and the amount of material to be stirred is large, the diameter of the mixing tank becomes larger and the stirrer blade becomes larger, which increases the power cost due to the operation of the stirrer.In the case of using a line mixer, the mixing power is slightly higher, but the construction cost and the process become complicated. There is a disadvantage that the operation maintenance cost is increased.

또, 유기용제함유폐수와 촉매유가 잘 혼합된 혼합 유기용제함유폐수 내의 혼합 유기용제를 폐수와 분리시키기 위한 분리조는 일반 유수분리기와 같이 단순 침전조 형태로 폐수를 침전시키고 상등되는 혼합 유기용제를 회수하는 기술은 침전시간이 오래 걸리는 단점이 있다In addition, the separation tank for separating the mixed organic solvent in the mixed organic solvent-containing wastewater from which the organic solvent-containing wastewater and catalyst oil are well mixed from the wastewater is a simple settling tank like a general oil-water separator to precipitate the wastewater and recover the superior mixed organic solvent. The technology has the disadvantage of taking a long settling time.

따라서, 유기용제함유폐수가 발생하는 현장에 간단하게 설치가 가능하고, 단일의 장치로 구성되어 있으면서도 회수효율이 우수한 유기용제함유폐수 처리 및 유기용제 회수장치의 개발이 필요하다.Accordingly, it is necessary to develop an organic solvent-containing wastewater treatment and organic solvent recovery device that can be simply installed at a site where organic solvent-containing wastewater is generated, and is composed of a single device and has excellent recovery efficiency.

상기 터빈펌프(205)는 2유체를 혼합하면서 토출하는 특수한 기능을 가진 펌프로, 터빈펌프(205)의 유입구는 2개로 구성되어 있는데, 제1 유입구(206)는 유량조정탱크(101)에 연결하고, 제2 유입구(207)는 촉매유 저장탱크(208)에 연결한 후 터빈펌프(205)를 가동하면 터빈펌프(205)에는 유기용제함유폐수와 촉매유가 동시에 유입되고, 터빈펌프 내에서 2유체가 혼합된 혼합 유기용제함유폐수가 발생하는데 상기 혼합 유기용제함유폐수는 강력한 토출력으로 원형파이프(202)를 통하여 다수개의 노즐(204)에서 빠른 속도로 혼합탱크(203) 내부로 분사되는데 이때 각각의 노즐(204)의 분사각도를 조정하게 되면 분사되는 혼합 유기용제함유폐수는 혼합탱크(203)내에서 수평 및 상하로 분사되면서 최대로 혼합된다.The turbine pump 205 is a pump having a special function of discharging while mixing two fluids, and the inlet of the turbine pump 205 is composed of two, and the first inlet 206 is connected to the flow control tank 101 And, when the second inlet 207 is connected to the catalyst oil storage tank 208 and then the turbine pump 205 is operated, the organic solvent-containing wastewater and the catalyst oil are simultaneously introduced into the turbine pump 205, and 2 A mixed organic solvent-containing wastewater mixed with a fluid is generated, and the mixed organic solvent-containing wastewater is sprayed into the mixing tank 203 at high speed from a plurality of nozzles 204 through a circular pipe 202 with strong discharge power. When the spraying angle of each nozzle 204 is adjusted, the mixed organic solvent-containing wastewater sprayed is maximally mixed while spraying horizontally and vertically in the mixing tank 203.

한편 혼합탱크(203)에 교반기(미도시)를 설치하고, 유기용제함유폐수와 촉매유를 각각 혼합탱크(203)에 투입하여 혼합하는 방법도 있으나 교반기의 날개 각도와 회전이 일 방향만으로 되어있어서 수평 혼합만 되고 교반기 회전을 반대로 하여도 여전히 수평혼합만 되어 혼합폭이 적어서 교반기만으로 혼합 시에는 혼합효율이 떨어질 수도 있다.Meanwhile, a stirrer (not shown) is installed in the mixing tank 203, and organic solvent-containing wastewater and catalyst oil are added to the mixing tank 203 and mixed, but the angle and rotation of the agitator are only one direction. Even if it is only horizontally mixed and the rotation of the stirrer is reversed, the mixing width is small because it is still only horizontally mixed, so when mixing only with the stirrer, the mixing efficiency may decrease.

도 4는 본 발명의 일실시예에 따른 노즐 조립도이다.4 is an assembly view of a nozzle according to an embodiment of the present invention.

본 발명의 일실시예에 따른 노즐(204)은 도 4에 도시된 바와 같이, 노즐(204)하부를 원형의 유동구(209)를 가진 형태로 제작하고, 노즐(204)이 조립되어지는 베이스(210) 상부는 원형홀(211)을 가지도록 제작하면, 베이스(210)를 원형파이프(201)에 용접하여 부착시킨 후에 노즐(204)의 유동구(209)를 원형홀(211)에 장착시켜 노즐(204)을 조립하게 되면 노즐(204)의 분사각도를 좌우나 상하로 조절할 수가 있게 된다.In the nozzle 204 according to an embodiment of the present invention, as shown in FIG. 4, the lower portion of the nozzle 204 is manufactured in a shape having a circular flow hole 209, and the base on which the nozzle 204 is assembled ( 210) If the upper part is manufactured to have a circular hole 211, after attaching the base 210 to the circular pipe 201 by welding, the flow port 209 of the nozzle 204 is mounted on the circular hole 211 When assembling the 204, the spray angle of the nozzle 204 can be adjusted left and right or up and down.

도 5는 본 발명의 일실시예에 따른 분리부를 도시한 구성도이다.5 is a block diagram showing a separation unit according to an embodiment of the present invention.

본 발명의 일실시예에 따른 분리부(300)는 도 5에 도시된 바와 같이, 상부에 VENT 2홀(301)이 부착된 사각형 형태의 분리탱크(302)와 분리탱크(302) 내부에 분리탱크(302) 하부로 유로가 형성되도록 공간을 두고 설치된 분리판(303)과 분리탱크(302) 상부에 분리된 혼합 유기용제 또는 물이 월류하여 외부로 배출될 수 있도록 다수개의 톱니가 형성된 웨어(304)를 포함하여 구성된다.Separation unit 300 according to an embodiment of the present invention, as shown in Figure 5, the upper part of the VENT 2 hole 301 is attached to the square-shaped separation tank 302 and the separation tank 302 is separated inside The separating plate 303 installed with a space to form a flow path under the tank 302 and the mixed organic solvent or water separated on the upper part of the separating tank 302 overflow and discharge to the outside. 304).

상기 분리탱크(302)에 혼합 유기용제함유폐수를 유입한 후 일정시간을 경과시키면 혼합 유기용제함유폐수 내의 혼합 유기용제는 비중에 따라 부유하거나 침강하면서 폐수와 확실한 층 분리가 되는데, 층 분리가 완료되면 제1배출구(305)와 제2배출구(306)를 통하여 혼합 유기용제와 폐수를 각각 배출시키면 혼합 유기용제와 폐수를 쉽게 분리시킬 수가 있게 된다.After a certain period of time elapses after the mixed organic solvent-containing wastewater is introduced into the separation tank 302, the mixed organic solvent in the mixed organic solvent-containing wastewater floats or settles according to the specific gravity, resulting in reliably layer separation from the wastewater. Then, when the mixed organic solvent and wastewater are respectively discharged through the first discharge port 305 and the second discharge port 306, the mixed organic solvent and wastewater can be easily separated.

도 6은 본 발명의 일실시예에 따른 회수부를 도시한 구성도이다.6 is a block diagram showing a recovery unit according to an embodiment of the present invention.

본 발명의 일실시예에 따른 회수부는 (400)는 도 6에 도시된 바와 같이, 하부에 히터(401)가 장착된 증류탑(402) 상부에 가스배출구(403)가 장착되고, 가스배출구(403) 후단에는 냉각기능이 있는 응축기(404)가 설치되며 응축기(404) 후단에는 수용성 유기용제탱크(405)가 설치되고 증류탑(402) 하부에는 촉매유 배출구(406)가 설치되는 것을 포함하여 구성된다.The recovery unit 400 according to an embodiment of the present invention is equipped with a gas outlet 403 on the top of the distillation column 402 equipped with a heater 401 at the bottom, as shown in FIG. 6, and the gas outlet 403 ) A condenser 404 having a cooling function is installed at the rear end, a water-soluble organic solvent tank 405 is installed at the rear end of the condenser 404, and a catalyst oil outlet 406 is installed at the bottom of the distillation column 402. .

분리탱크(302)에서 분리되어 회수된 혼합 유기용제가 증류탑(402)으로 유입되고 히터(401)에 의해서 증류탑(402) 내부온도가 대략 80℃ 이상이 되면 수용성 유기용제 중 비등점이 낮은 에틸아세테이트나 이소프로필알콜 같은 물질은 증발하여 가스배출구(403)를 통하여 증류탑(402) 외부로 가스로 배출되는데, 메틸에틸케톤 같은 비등점이 더 높은 수용성 유기용제도 130℃ 부근 온도에서 거의 증발하여 가스로 변하므로 증류탑(402) 내부온도를 130℃ 정도에서만 운전하면 수용성 유기용제는 거의 증발하게 되고 비등점이 200℃ 정도가 되는 촉매유만 증류탑(402)에 남게 된다.When the mixed organic solvent separated and recovered from the separation tank 302 flows into the distillation column 402 and the internal temperature of the distillation column 402 by the heater 401 is approximately 80°C or higher, ethyl acetate or ethyl acetate with a low boiling point among the water-soluble organic solvents Substances such as isopropyl alcohol evaporate and are discharged as a gas to the outside of the distillation column 402 through the gas outlet 403. Since a water-soluble organic solvent with a higher boiling point, such as methyl ethyl ketone, almost evaporates at a temperature around 130° C. When the internal temperature of the distillation column 402 is operated only at about 130°C, the water-soluble organic solvent is almost evaporated, and only the catalyst oil having a boiling point of about 200°C remains in the distillation column 402.

한편 가스배출구(403)에서 가스로 배출된 80℃ 이상의 수용성 유기용제는 가스배출구(403) 후단에 설치된 냉각 기능이 있는 응축기(404)에서 40℃ 미만으로 저온 화 되면서 급격히 응축되어 액상으로 변한 뒤 수용성 유기용제탱크(405)로 저장되어 원료로 재사용할 수가 있게 된다.On the other hand, the water-soluble organic solvent of 80℃ or higher discharged as gas from the gas outlet 403 is rapidly condensed to a liquid state as the temperature is lowered to less than 40℃ in the condenser 404 with cooling function installed at the rear end of the gas outlet 403. It is stored in the organic solvent tank 405 and can be reused as a raw material.

또한 증류탑(402)에 남은 촉매유는 촉매유 배출구(406)를 통하여 회수한 후 촉매유 저장탱크(208)로 보내서 유기용제함유폐수 처리에 재사용할 수가 있게 된다.In addition, the catalyst oil remaining in the distillation column 402 is recovered through the catalyst oil outlet 406 and then sent to the catalyst oil storage tank 208 so that it can be reused for treatment of organic solvent-containing wastewater.
