Description

폐아크릴 재생공정에서 나오는 폐유로부터 아크릴 원료를 획득하는 추출방법{Extraction method to obtain acrylic raw material from waste oil from waste acrylic recycling process}BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an extraction method for obtaining an acrylic raw material from waste oil from a waste acrylic recycling process,

본 발명은 폐아크릴 재생공정 상에서 잔여 폐기물로서 폐기는 폐유를 이용하여 폐유로부터 아크릴 원료를 획득하기 위한 추출방법에 관한 것이다. The present invention relates to an extraction method for obtaining an acrylic raw material from waste oil using waste oil as a residual waste in a waste acrylic recycling process.

아크릴은 폴리메타크릴레이트(PMMA:Polymethylmethacrylate)와 메틸메타크릴레이트(MMA:Methylmethacrylate)를 의미하는 것으로, 아크릴은 광투과율이 유리보다 높고, 투명성이 플라스틱 중에 으뜸이며, 제작의 편리성과 색상 및 형태변형의 다양성으로 각종분야에서 많이 사용되고 있다.Acrylic means polymethylmethacrylate (PMMA) and methylmethacrylate (MMA). Acrylic has higher light transmittance than glass and transparency is the best among plastic. And is widely used in various fields.

아크릴은 각종 분야에 적용되는 과정에서 자투리 아크릴이 발생하게 되며, 이 자투리 아크릴은 사용 기준보다 작기 때문에 사용이 불가능하여 폐아크릴로서 취급되게 된다. Acrylic is generated in the course of application to various fields, because it is smaller than the standard of use, so it can not be used, it will be treated as waste acrylic.

이러한 폐아크릴은 소각하여 처리할 수도 있으나, 아크릴은 고가의 자원이기 때문에 소각처리하기 보다는 재활용될 수 있도록 재생되어 사용되고 있다. These waste acrylics can be treated by incineration, but since acrylic is an expensive resource, it is being recycled and recycled rather than incinerated.

상기 폐아크릴을 재활용하는 방법은 폐아크릴을 용융, 정제하여 아크릴 원료를 재생하게 되는데, 이러한 폐아크릴을 용융, 정제하여 아크릴원료를 재생하는 경우, 투입된 폐아크릴이 모두 아크릴원료로 재생되는 것은 아니며, 투입된 폐아크릴에 대해 85 중량%의 아크릴원료가 재생되고, 나머지는 15중량%의 폐유가 나오게 된다. The waste acrylic is recycled by melting and refining the waste acrylic to regenerate the acrylic raw material. When the acrylic raw material is regenerated by melting and refining the waste acrylic, all the waste acrylic acrylate is not regenerated as an acrylic raw material, 85% by weight of the acrylic raw material is recycled with respect to the charged waste acrylic, and the remaining amount is 15% by weight.

현재까지, 폐아크릴을 이용해 아크릴원료를 재생하는 과정에서 나오는 이러한 폐유는 그대로 폐기물처리되는 수밖에 없으며, 이에 따라 막대한 자원손실이 발생하는 문제가 있었다. Until now, such waste oil from the process of recycling acrylic raw materials using waste acrylic is inevitably subjected to waste disposal, resulting in massive resource loss.

아울러, 폐아크릴을 통한 아크릴원료 재생과정에서 나오는 이러한 폐유는 폐기물처리가 유독 쉽지 않기 때문에, 직접 업체공장에서 폐유를 일정기간 동안 보관관리해야 하고, 이로 인해 폐유를 보관관리하는데 필요한 유지비용이 많이 소요될 뿐 아니라, 이러한 폐유는 일부 몰상식한 업체들이 폐기물 처리비용을 줄이기 위해 불법적으로 하천등에 버려지게 됨으로써, 생태계 파괴등 환경의 심각한 오염을 발생시키는 원인이 되었다. In addition, since the waste oil from the acrylic raw material recycling process through the waste acrylic is not easily poisoned, it is necessary to directly store the waste oil in the factory for a certain period of time, In addition, such waste oil has been caused by illegal abandonment of rivers and the like to reduce waste disposal costs, resulting in severe pollution of the environment, such as destruction of ecosystems.

The present invention relates to an extraction method for obtaining an acrylic raw material from waste oil which can extract an acrylic raw material from waste oil by using waste oil generated when an acrylic raw material is regenerated by melting and refining waste acrylic such as squalid acrylic generated in the whole industry.

여기서, 폐아크릴 재생공정에서 나오는 폐유는 통상적으로 관련산업의 공장등에서 폐기전까지 드럼통에 채워져 보관되고 있으며, 이러한 폐유는 점성이 매우 높아 끈적끈적한 고점성상태이다. Here, the waste oil from the waste acrylic recycling process is usually stored in a drum until it is disposed of at a factory of a related industry or the like, and the waste oil is in a viscous state and sticky and viscous state.

본 발명은 1차추출액획득단계(s10), 2차추출액획득단계(s20), 혼합액 제조단계(s30), 재생원료 획득단계(s40)를 포함하도록 구성된다. The present invention is configured to include a first extraction liquid obtaining step (s10), a second extraction liquid obtaining step (s20), a mixed liquid producing step (s30), and a regenerated raw material obtaining step (s40).

이하에서 본 발명은 폐유 3드럼 즉, 폐유 540kg으로부터 재생원료를 획득하는 것에 대한 설명이 이루어진다. Hereinafter, the present invention will be described in terms of obtaining recycled raw materials from 3 drums of waste oil, that is, 540 kg of waste oil.

1차추출액획득단계(s10)는 폐아크릴 재생공정에서 나오는 폐유를 500~800℃로 가열하고, 가열에 의해 생성된 가스를 냉각하여 응축되는 응축액을 수집하여 1차추출액을 획득하는 과정이다. In the step (s10) of obtaining the primary extract, the waste oil from the waste acrylic recycling process is heated to 500 to 800 ° C, the gas generated by heating is cooled, and the condensed liquid is collected to obtain the primary extract.

예를 들어, 폐아크릴 재생공정에서 나오는 폐유를 1차가열탱크(11)에 넣고, 버너 또는/및 전기히터로 1차가열탱크(11)를 가열함으로써 폐유를 500~800℃로 가열하면, 폐유의 가열에 의해 가스가 발생하고, 발생된 가스는 냉각수가 채워진 1차냉각수탱크(13) 내에 설치된 코일형태의 응축관(14)을 지나면서 냉각되어 응축됨으로써 응축액이 발생하게 되며, 이 응축액은 응축관(14)에서 배출되면서 원재료인 폐유가 완전히 소모될 때까지 8~12시간 동안 1차수집탱크(18)에 떨어지면서 수집됨으로써 1차추출액을 획득할 수 있게 된다. For example, when the waste oil from the waste acrylic recycling process is placed in the primary heating tank 11 and the primary oil tank 11 is heated by the burner and / or the electric heater to heat the waste oil to 500 to 800 ° C, And the generated gas is cooled and condensed through a coil-shaped condensing tube 14 provided in the primary cooling water tank 13 filled with the cooling water, thereby generating a condensed liquid. The condensed liquid is condensed The primary extraction liquid can be obtained by being collected while falling into the primary collection tank 18 for 8 to 12 hours until the waste oil, which is a raw material, is exhausted from the pipe 14 and completely consumed.

본 발명에서 1차냉각수탱크(13)에 채워진 냉각수는 0~20℃로 이루어져, 가열된 폐유로부터 생성된 가스가 응축관(14) 내에서 0~20℃의 냉각온도에 의해 냉각되어 응축될 수 있다. In the present invention, the cooling water filled in the primary cooling water tank 13 is 0 to 20 ° C, and the gas generated from the heated waste oil is cooled and condensed at a cooling temperature of 0 to 20 ° C in the condensing tube 14 have.

본 발명에서 1차추출액획득단계(s10)에서 획득된 1차추출액은 최초 공급된 폐유에 대해 1:1의 중량비율만큼 얻어지게 된다. In the present invention, the primary extract obtained in the step (s10) of obtaining the primary extract liquid is obtained in a weight ratio of 1: 1 with respect to the initially supplied waste oil.

2차추출액획득단계(s20)는 1차추출획득단계(s10)를 거쳐 획득된 1차추출액을 450~750℃로 가열하고, 가열에 의해 생성된 가스를 냉각하여 응축되는 응축액을 수집하되, 전체응축액이 수집되는 시간 중 초기 소정시간과 마지막 소정시간을 제외한 중간시간대에 수집되는 응축액을 수집하여 2차 추출액을 획득하는 과정이다. 본 발명의 2차추출액획득단계(s20)에서 최초 공급된 1차추출액이 완전히 소모될 때까지 응축액이 수집되게 되며, 이 응축액이 수집되는 전체시간은 10~14시간으로 이루어질 수 있다. In the second extraction liquid obtaining step s20, the primary extraction liquid obtained through the first extraction obtaining step s10 is heated to 450 to 750 ° C, the gas generated by heating is cooled to collect the condensed liquid, Collecting a condensate collected during an intermediate time period except for an initial predetermined time and a final predetermined time of the condensate collecting time to acquire a secondary extract. The condensate is collected until the first extraction liquid initially supplied in the second extraction liquid obtaining step (s20) of the present invention is completely consumed, and the total time during which the condensate is collected may be 10 to 14 hours.

예를 들어, 1차수집탱크(18)로부터 수집된 1차추출액이 2차가열탱크(21)로 공급되며, 버너로 2차가열탱크(21)를 가열함으로써 1차추출액을 450~750℃로 가열하면, 1차추출액의 가열에 의해 가스가 발생하고, 발생된 가스는 냉각수가 채워진 2차냉각수탱크(23) 내에 설치된 코일형태의 응축관(24)을 지나면서 냉각되어 응축됨으로써 응축액이 발생되고, 이 응축액을 수집할 수 있게 되는데, 이때, 2차가열탱크(21)에 공급된 1차추출액이 완전히 소모될 때까지 응축액이 수집되며, 이 응축액이 수집될 수 있는 전체시간 중 초기시간과 마지막시간에는 응축액이 불순물이 포함되어 있어, 중간시간대의 응축액만을 수집하여 2차추출액이 획득될 수 있다. For example, the primary extraction liquid collected from the primary collection tank 18 is supplied to the secondary heating tank 21, and the primary extraction liquid is heated to 450 to 750 占 폚 by heating the secondary heating tank 21 with the burner When heated, the gas is generated by heating the primary extraction liquid. The generated gas is cooled and condensed through a coil-shaped condensation tube 24 provided in the secondary cooling water tank 23 filled with the cooling water, thereby generating a condensate , The condensate can be collected. At this time, the condensate is collected until the primary extract supplied to the secondary heating tank 21 is completely consumed, and the initial time and the final time during which the condensate can be collected At the time, the condensate contains impurities, so that only the intermediate time condensate can be collected and a second extract can be obtained.
