Description

Recycling method of packaging waste using solvent.

본 발명은 각종 윤활유, 첨가유, 식용유, 세제 등과 같은 포장용기(폴리에치렌)폐기물을 수거하여 건식 분쇄하면서 기름 등의 오염원과 분쇄물을 분리 수집하되, 분쇄물은 다시 유기용제로 클리닝하여 순수한 폴리에치렌 분쇄물을 얻어 재활용케 하며, 불 순화된 용제는 증발 회수하여 재사용하고, 잔유유분과 고형 불순물은 여과 분리하여 유분은 연료유로 고형물케이크는 폐기 처리하므로서, 환경오염 없이 각종 수지포장용기들을 처리할 수 있는 방법에 관한 것이다.The present invention is to collect and pulverize the packaging container (polyethylene) waste, such as various lubricants, additive oils, cooking oils, detergents and the like, while collecting and crushing the pollutants and oils such as oil separately, the pulverized again by cleaning with an organic solvent Obtained and recycled polyethylene crushed products, recycled and recycled impurity solvents, filter off the residual oil and solid impurities, and discard the solid cake with oil as fuel oil. It is about how it can be processed.

일반적으로 각종 윤활유, 첨가제, 식용유, 세제 등과 같은 포장용기들의 처리방법은 습식 수세분쇄방법으로 폐수시설을 갖추어야 한다.In general, the treatment of packaging containers such as various lubricants, additives, cooking oils, detergents, etc. should be equipped with a waste water facility by a wet washing method.

그러나 시설미비와 기술부족으로 산, 알카리, 세척첨가제 등의 무단방유가 전국 어디에나 이루어지고 있는 현실이기 때문에 수질이나 토양 오염이 가중되고 있으며 이로 인하여 환경폐해가 심각할 뿐 아니라 회수재료 역시 양질이 되지 못하여 재활용되는 용도도 매우 제한적인 것이었다.However, due to lack of facilities and lack of technology, unauthorized oils such as acids, alkalis, and cleaning additives are being carried out all over the country, so water and soil pollution are increasing. This is not only a serious environmental hazard, but also a poor quality of recovered materials. Recycling was also very limited.

즉 다시 설명하면 폐기되는 각종 포장용기들의 재활용이 효과적으로 이루어지지 못할 뿐 아니라 미흡한 처리로 인하여 환경오염을 가중시키게 되는 등의 문제점이 있는 것이었다.In other words, there was a problem that not only the recycling of various packaging containers that were discarded was effectively made, but also increased environmental pollution due to insufficient treatment.

본 발명은 이러한 종래의 제반 문제점을 시정하고자 폐기 처분되고 있는 각종 수지포장용기들을 회수한 다음 각 성분별로 분리 추출하여 수지는 재활용자원으로 유분은 연료유로, 잔류물인 이물질은 매립 처리하므로서 환경오염 없이 효과적으로 처리할 수 있도록 한 것이다.The present invention recovers various types of resin packaging containers that are disposed of in order to correct these problems, and then separates and extracts the resins for each component. It is to be handled.

상기 목적을 달성하기 위하여 본 발명은 폴리에치렌으로 성형된 각종 포장용기들을 수집한 다음 분쇄하고, 상기 분쇄된 분쇄물은 세척통에서 유기용제로 세척한 다음 폴리에치렌 분쇄물은 자원으로 재활용케 하고, 세척시 사용된 유기용제는 오일이나 기타 불순물들과 분리 회수한 다음 재 사용케 하고, 잔존하는 유분과 기타 불순물은 다시 분리 여과하여 유분은 연료유로 사용하고, 고형물 케이크는 폐기토록 한 것이다.In order to achieve the above object, the present invention collects and then pulverizes various packaging containers formed of polyethylene, and the pulverized pulverized product is washed with an organic solvent in a washing container and the poly ethylene pulverized material is recycled as a resource. The organic solvent used for washing is separated and recovered from oil and other impurities, and then reused. The remaining oil and other impurities are separated and filtered again, and the oil is used as fuel oil, and the solid cake is discarded.

이하 본 발명의 실시예를 첨부도면에 따라 공정별로 상세히 설명하면 다음과 같다.Hereinafter, an embodiment of the present invention will be described in detail by process according to the accompanying drawings.

도1은 본 발명 공정도이고, 도2 및 도3은 도1공정도를 확대 도시한 것이고, 본 발명의 공정은 크게 제1공정인 수집분쇄공정과, 제2공정인 세척공정 및 제3공정인 용제증발 회수공정으로 크게 분류할 수 있으며 상기 각 공정을 상세히 설명하면 다음과 같다.Figure 1 is a process diagram of the present invention, Figures 2 and 3 is an enlarged view of the process diagram of Figure 1, the process of the present invention is largely the first process of the collection grinding process, the second process of the washing process and the third process solvent The evaporation recovery process can be broadly classified and described in detail for each process as follows.

제1공정 : 포장용기 수거 및 건식 분쇄공정1st process: packing container collection and dry grinding process

폐기 처분되는 각종 유제통(오일통), 농약통, 세제통 등을 분리 수거하여 폐기물 수집통(2)에 저장하고, 상기 폐기물 수집통(2)에서 용기에 잔류하는 각종 잔류이물질 즉 오일이나 세제 및 각종 이물질은 오일드레인통(4)으로 수집되고 오일드레인통(4)에 수집된 혼합물은 차후 펌프(6)를 통하여 증발기로 이송 분리 처리되게 한다.Various waste oil containers (oil container), pesticide container, detergent container, etc. which are disposed of are separately collected and stored in the waste collection container (2), and various residual foreign matters remaining in the container in the waste collection container (2), namely, oil or detergent, Various foreign matters are collected in the oil drain container (4) and the mixture collected in the oil drain container (4) is subsequently sent to the evaporator through the pump (6).

각종 잔류이물질이 1차 배출된 포장용기들은 콘베어(8)를 통하여 분쇄기(10)로 공급 분쇄되고, 분쇄된 분쇄물은 송풍기(12)를 통하여 싸이크론유분리기(14)로 공급되고 싸이크론유분리기(14)에서 2차로 잔류하는 이물질은 걸름망 아래로 수집되고 수집된 이물질은 역시 펌프(6)를 통하여 증발기로 공급되게 한다.Packaging containers in which various residual foreign matters are first discharged are supplied to the grinder 10 through the conveyor 8, and the pulverized powder is supplied to the cyclone oil separator 14 through the blower 12 and the cyclone oil separator ( The foreign matter remaining secondary in 14) is collected under the strainer and the collected foreign matter is also supplied to the evaporator through the pump (6).

싸이크론유분리기(14)에서 2차로 유분리된 분쇄물은 분쇄재료통(16)에 저장되고, 분쇄재료통(16) 아랫쪽에는 오일드레일통(18)이 설치되어 있어 2차 분리되지 못한 잔류이물질을 한번 더 분리하여 증발기로 공급되게 하므로서 제1공정인 폐기물의 수거 및 분쇄공정이 완료된다.The pulverized matter which is secondarily separated from the cyclone oil separator 14 is stored in the pulverization material container 16, and the oil foreign matter container 18 is installed below the pulverization material container 16, so that the remaining foreign matters that cannot be separated secondarily are not. Is separated once more and is supplied to the evaporator, thereby completing the first step of collecting and crushing waste.

제2공정 : 세척공정2nd process: washing process

본 공정은 제1공정에서 분쇄된 폐용기분쇄물을 세척하여 분쇄물에 묻어있는 이물질을 완전히 세척하여 순수한 수지분쇄물과 세척작업시 발생한 세척용제를 분리하는 공정이다.This process is to wash the waste container crushed in the first step to completely clean the foreign matter in the pulverized to separate the pure resin pulverized product and the cleaning solvent generated during the cleaning operation.

즉 분쇄재료통(16)에 수집된 수지분쇄물(약1Kg)을 가고차(20)를 통하여 세척탱크(22) 내에 투입한 다음 수지분쇄물에 잔류하는 이물질을 용제 처리함으로서 수지 분쇄물이 깨끗이 세척되게 한다.That is, the resin powder (about 1 Kg) collected in the grinding material container 16 is introduced into the washing tank 22 through the Gacha 20, and then the resin powder is cleaned by treating the foreign matter remaining in the resin powder with the solvent. Allow to be washed.

이때 사용되는 유기용제의 양은 약1ℓ정도이고, 상용성이 우수한 용제를 사용함과 동시에 비등점차이 분리가 용이한 용제 즉, 톨루엔이나 제3염화에치렌 혹은 제4염화에치렌 등을 사용하는 것이 이상적이다.At this time, the amount of the organic solvent used is about 1 L, and it is ideal to use a solvent having excellent compatibility and easy separation of boiling point difference, that is, toluene, tertiary ethylene chloride or tertiary ethylene ethylene. .

또한 세척탱크의 형태로서는 필요용적 호리존탈형(가로형)개폐식탱크로서 탱크내에 레일, 가고차, 가열장치, 가고운동장치를 부착설치하고, 세척 완료된 후 증발기(24)로 액이송, 진공감압배기, 건조개방 후 수지분쇄물을 얻어낸다.In addition, as a type of washing tank, the necessary volume horizontal type opening / closing tank is installed in the tank with a rail, a go-car, a heating device, and a go-carrying device, and after the cleaning is completed, the liquid is transferred to the evaporator 24, the vacuum pressure exhauster, After drying, a resin pulverized product is obtained.

상기에서 얻어진 수지분쇄물(23)은 별도의 저장통(26)에 저장되었다가 재활용자원으로 사용되며 세척탱크(22)에서 발생한 세척용제는 공급관(28)을 통하여 증발기(24)로 이송 공급되어 증발회수공정을 통하여 회수재사용 된다.The resin pulverized product 23 obtained above is stored in a separate storage container 26 and used as a recycling resource. The cleaning solvent generated in the cleaning tank 22 is transferred to the evaporator 24 through the supply pipe 28 and evaporated. It is recycled through the recovery process.

제3공정 : 용제회수공정Third Process: Solvent Recovery Process

제2공정에서 사용된 세척용제나 제1공정에서 분리 수거된 오일 등 이물질을 증발기(24)를 통하여 세척용제와 혼합 이물질로 분리한 다음, 용제는 재활용하고, 혼합 이물질은 오일과 케이크로 분리하는 공정이다.The foreign matter such as the cleaning solvent used in the second process or the oil separated and collected in the first process is separated into the cleaning solvent and mixed foreign matter through the evaporator 24, and then the solvent is recycled, and the mixed foreign matter is separated into oil and cake. It is a process.

좀 더 상세하게 설명하면 공급관(28)을 통하여 이물질을 함유하는 세척용제가 감압상태를 유지하는 증발기(24)내로 분사되면, 세척용제는 기체화되어 응축기(30)로 공급되고, 응축기(30)에서 용제는 냉각 응축되어 레시버탱크(32)로 수집된다.In more detail, when the cleaning solvent containing the foreign matter is injected into the evaporator 24 maintaining the reduced pressure through the supply pipe 28, the cleaning solvent is gasified and supplied to the condenser 30, the condenser 30 In the solvent is cooled condensate and collected in the receiver tank (32).

이때 증발기(24)내에는 교반기(25)가 설치되어 있어 세척용재의 기화를 촉진시키게 될 뿐 아니라 거의 완전한 용제 재활용을 기대할 수 있게 된다.At this time, the stirrer 25 is installed in the evaporator 24 to promote vaporization of the cleaning material and to expect almost complete solvent recycling.

상기에서 세척용제가 기화배기되고 나면 증발기(24)내에는 유제와 가타 이물질이 잔류하게 되고, 상기 혼합물은 냉각기(34)로 이송 공급되어 냉각시킨 다음 필타프레스(36)로 투입하고, 필타프레스(36)로 투입된 이물질은 압착시키므로서 불순케이크(38)와 유제(오일)로 분리 추출되고, 추출된 유제는 오일저장탱크(40)에 저장되었다가 연료유로 재활용된다.After the cleaning solvent is vaporized and exhausted in the evaporator 24, the oil and other foreign substances remain in the evaporator 24, and the mixture is fed to the cooler 34, cooled and then introduced into the filter press 36, and the filter press ( The foreign matter introduced into 36 is compressed and separated into impurity cake 38 and an oil (oil), and the extracted oil is stored in the oil storage tank 40 and recycled as fuel oil.

이때 필타프레스기(36)를 이용하지 않을 경우에는 냉각기(34)와 별도로 연결된 디칸타케이크 분리기(42)를 이용하여 불순케이크와 유제(오일)로 분리시킨 다음 유제는 오일저장탱크(40)에 저장, 연료유로 재활용하고, 불순케이크는 폐기하게 된다.In this case, when the filter press 36 is not used, it is separated into an impurity cake and an oil (oil) by using a decanter cake separator 42 connected to the cooler 34 separately, and then the emulsion is stored in the oil storage tank 40. It is then recycled into fuel oil and the impure cake is discarded.

이때 증발기(24)에서 기화되어 응축기(30)로 이송 냉각 응축된 세척용제는 레시버탱크(32)로 이송되고, 레시버탱크(32)에서 응축된 세척용제는 용제저장탱크(44)에 저장되었다가 다시 제2공정에 설치된 세척탱크(22)로 공급되어 재활용하게 된다.At this time, the washing solvent vaporized in the evaporator 24 and transferred to the condenser 30 is cooled and condensed to the receiver tank 32, and the washing solvent condensed in the receiver tank 32 is stored in the solvent storage tank 44. After that, it is supplied to the washing tank 22 installed in the second process and recycled.

또한 응축기(30)에서 미응축된 잔류세척용제와 소량의 수분은 다시 진공펌프(46)를 통하여 용제 재회수장치로 공급되어 재응축되게 하므로서 용제의 회수 효율을 증진시킴과 동시에 불응축가스나 수분만 외부로 배기되게 하여 대기오염을 최소화하게 된다.In addition, the remaining non-condensed solvent and a small amount of water condensed in the condenser 30 are supplied back to the solvent recovery unit through the vacuum pump 46 to be recondensed, thereby improving the recovery efficiency of the solvent and at the same time, only the non-condensed gas or water. Exhaust to the outside to minimize air pollution.

용제 재회수장치는 본인이 선출원한 (특허출원제94-40779호, 용제를 이용한 염화비닐 폐전전의 회수처리방법)내용에 기재된 용제 재회수장치와 동일하나 다시 한번 더 개략적으로 설명하면 다음과 같다.Solvent reclaimer is the same as the solvent reclaimer described in the contents (Patent Application No. 94-40779, the method of recovery of vinyl chloride waste using solvents), which was previously filed.

즉 레시버탱크(32)에서 미응축된 수분이나 가스가 제1,2혼합탑(48)(50)으로 공급되면 제1,2혼합탑(48)(50)하단 일측에 구성된 순환펌프(52)(54)로 흡입되고, 순환펌프(52)(54)에 흡입된 가스는 유제와 혼합 액화되어 혼합액이 되고, 상기 혼합액 중 일부는 증류기(56)로 공급되고 나머지는 제1,2혼합탑(48)(50)으로 공급 분사되는 작동을 연속 반복하게 된다.That is, when water or gas that is not condensed in the receiver tank 32 is supplied to the first and second mixing towers 48 and 50, the circulation pump 52 configured at one side of the lower ends of the first and second mixing towers 48 and 50. (54) and the gas sucked into the circulation pump (52) (54) is liquefied mixed with the emulsion into a mixed liquid, some of the mixed liquid is supplied to the distiller 56, the rest of the first and second mixing tower The operation of supply injection to 48 and 50 is repeated continuously.

상기에서 증류기(56)로 공급된 혼합액은 보일러(58)의 열원에 의해 가열된 증류기(56)내에서 용제는 다시 기화되어 응축기(60)로 이송되고, 응측기(60)로 이송된 용제 가스는 응축 액화되어 용제저장탱크(44)로 공급되어 세척용제의 회수율을 최대로 높이게 된다.The mixed liquid supplied to the distillation 56 is the solvent in the distillation 56 heated by the heat source of the boiler 58 is vaporized again to the condenser 60, the solvent gas transferred to the condenser 60 The condensation liquid is supplied to the solvent storage tank 44 to maximize the recovery rate of the cleaning solvent.

미 설명부호 (70)은 벙커C유 저장탱크, (72)는 써비스탱크, (74)는 팽창탱크, (76)은 열매저장탱크이다.Reference numeral 70 is a bunker C oil storage tank, 72 is a service tank, 74 is an expansion tank, and 76 is a fruit storage tank.

상기에서 설명한 바와 같이 분리 수거된 포장용기를 분쇄하면서 수지분쇄물과 유제(오일)을 분리 선별하고, 수지분쇄물은 세척용제로 세척되는 세척공정을 통하여 수지분쇄물에 부착된 유제나 불순물을 완전히 세척하므로서 순수한 수지분쇄물을 얻은 다음 재활용 자원으로 활용케 하고, 분쇄공정과 세척공정에서 얻어진 유제나 세척용제는 용제 회수공정을 통하여 세척용제만 재활용 사용케 하고, 세척용제가 분리추출된 혼합물은 다시 필타프레스기를 이용하여 압착하므로서 유제(오일)와 불순케이크로 분리 수거되고, 이때 유제는 연료유로 재활용하고, 불순케이크는 폐기 처분케 하므로서 본 발명이 완료된다.As described above, the resin powder and oil (oil) are separated and sorted by pulverizing the separately collected packaging container, and the resin powder is completely removed from the oil or impurities adhered to the resin powder through a washing process washed with a cleaning solvent. Pure resin powder is obtained by washing and then used as recycling resources. The emulsion or washing solvent obtained in the crushing and washing process can be recycled only through the solvent recovery process, and the mixture from which the washing solvent is extracted The present invention is completed by separating the oil (oil) and the impurity cake by pressing with a filter press, and recycling the oil to fuel oil and disposing of the impurity cake.

따라서 본 발명은 환경오염의 정도가 날로 심각해지고 있는 각종 윤활유, 첨가유, 식용유, 세제 등과 같은 포장용기를 오염 없이 건식 분쇄한 다음 순수한 수지분쇄물과 오일 및 불순케이크로 분리 추출하여 수지 분쇄물은 자원으로, 오일은 연료유로 재활용케 하므로서 환경오염 없이 각종 포장용기들을 처리할 수 있게 될 뿐 아니라 자원을 재활용할 수 있게 되는 등의 효과가 있는 것이다.Therefore, in the present invention, dry crushed packaging containers such as lubricants, additive oils, edible oils, detergents, etc., which are becoming increasingly serious, are polluted with pure resin pulverized products, oils and impure cakes, and the resin pulverized products are As a resource, oil can be recycled as fuel oil, so that various packaging containers can be disposed of without environmental pollution, as well as resources can be recycled.
