본 발명은 일정기간 사용후 교체하여 소각하거나 버려지므로 환경오염의 주원인이 되는 산업용 폐오일의 오염성분을 완벽히 제거하여 주므로 폐오일을 재생처리하여서 재활용이 가능케하는 것으로, 오일의 낭비 및 오일의 오염으로 인한 기계의 고장 및 노후화를 예방하고 폐오일의 발생단계에서 오일오염을 방지하고저 한 산업용 폐오일 재생 방법 및 장치에 관한 것이다.The present invention completely incinerated or discarded after use for a certain period of time, thus completely removing the contaminants of industrial waste oils, which are the main causes of environmental pollution, and thus recycling the waste oils by recycling them, resulting in waste of oil and contamination of oils. The present invention relates to a method and apparatus for preventing waste of the machine and aging, preventing oil pollution at the stage of generating waste oil, and reducing industrial waste oil.

종래 오일제조공장에서 생산된 신유를 사용함에 따라 외부로부터 이물질의 혼입과 미세한 마모분, 수분 기타 가스에 의해 1차적으로 오염되고, 이 오염성분에 의해 2차적으로 화학적 변화를 일으켜 수지성물질 및 산화물을 생성하고 오일의 오염을 가속시켜 폐오일화되었다.As the new oil produced in the conventional oil manufacturing plant is used, it is primarily contaminated by the mixing of foreign matters, fine abrasion, moisture, and other gases from the outside, and the chemicals are secondaryly changed by this contaminant, resulting in resinous substances and oxides. And waste oil by accelerating the contamination of the oil.

이러한 폐오일화를 방지하기 위해 여러가지 여과재를 사용하거나 원심력을 이용한 방법에 의하여 최소 5미크론 정도의 입자상의 오염물질만을 제거하여 기계고장 및 노후화 예방이나 일정기간 오일의 수명연장을 그 목적으로 사용되고 있다.In order to prevent such waste oiling, it is used for the purpose of preventing mechanical failure and aging or extending oil life for a certain period of time by removing particulate contaminants of at least 5 microns by using various filter media or centrifugal force.

그러나 종래의 문제점으로는 여과재의 제조기술상의 문제점으로 약 5미크론 이하의 입자제거는 불가능하며, 유동성 물질(수분, 수지성물질, 산화물, 기타 가스등)의 제거가 불가능하다.However, the conventional problem is that it is impossible to remove particles of about 5 microns or less due to problems in the manufacturing technology of the filter medium, and it is impossible to remove fluid substances (moisture, resinous material, oxide, other gas, etc.).

또 오일과 오염물의 비중차이가 작은 물질의 제거가 불가능하며, 2차적인 화학변화를 일으키는 1미크론이하의 미세한 입자 및 수분의 제거가 불가능하여 폐오일이 발생한다.In addition, it is impossible to remove substances with a small difference in specific gravity between oil and contaminants, and it is impossible to remove fine particles and water of less than 1 micron, which cause secondary chemical changes, resulting in waste oil.

또한, 폐오일은 재생처리가 되지 않아 재활용이 불가능하며, 수지성물질의 제거가 되지 않으며, 이물질의 흡착으로 인한 기계고장예방이 불가능하였다.In addition, the waste oil is not recycled because it is not recycled, it is not possible to remove the resinous material, preventing mechanical failure due to the adsorption of foreign matter.

그리고, 고점도 오일의 경우 여과재의 눈막힘 현상에 의한 압력 상승으로 사용불가능하고, 저온에서는 점도 상승에 따라 저온에서 사용이 불가능하였으며 잦은 소모품의 교체 및 오일의 교환에 따른 경제적 손실이 뒤따르는 문제가 있었다.In addition, in the case of high viscosity oil, it is impossible to use due to the pressure increase due to clogging of the filter medium, and at low temperatures, it is impossible to use it at low temperatures due to the viscosity increase, and there is a problem of frequent replacement of consumables and economic loss due to oil exchange. .

본 발명은 이와 같은 종래의 문제점을 해결하기 위하여 진공 및 쿨롱(COULOMB)법칙의 전기력을 이용하여 진공내에서의 유체는 비등점이 강하되므로 상온에서 증류되는 성질을 이용 진공도를 유지하는 용기에 폐오일을 유입시키어서 오일속의 수분, 수지성 물질, 산화물, 가스등을 제거한 후 초고전압이 흐르는 용기내로 오일을 통과시켜주어서 5미크론 이상의 입자뿐 아니라, 종래의 기술로는 제거할 수 없었던 1미크론 이하 0.05미크론(표면에 대전될 수 있는 입자의 한계사이즈)크기의 입자까지 제거하여 폐오일의 재생 및 재활용이 가능토록 한 것으로 이를 첨부 도면에 의거 상세히 설명하면 다음과 같다.The present invention uses the electric force of the vacuum and Coulomb law in order to solve such a conventional problem, since the boiling point of the fluid in the vacuum drops so that the waste oil in the container to maintain the degree of vacuum using the property of distillation at room temperature It removes moisture, resinous substances, oxides, and gases in the oil, and then passes the oil through an ultra-high voltage vessel to not only particles of 5 microns or more, but also 0.05 microns or less of 1 micron or less that cannot be removed by conventional techniques. The limit size of the particles that can be charged on the surface) to remove the particles of the size to enable the recycling and recycling of waste oil as described in detail according to the accompanying drawings as follows.

본 발명은 내부에 다수의 구멍(12b)은 뚫은 증류 파이프(12a)를 일정길이로 절단하여 수직상으로 증류층(12)으로된 진공탱크(2) 상단측면에 오일흡입펌프(1)를 통해 흡입되는 유입파이프(3a)를 설치 그 선단에 노즐(3)를 장치한다.According to the present invention, a plurality of holes (12b) therein are cut through a distillation pipe (12a) to a predetermined length through an oil suction pump (1) on the upper side of the vacuum tank (2) vertically formed into a distillation layer (12). The inlet pipe 3a to be sucked is installed, and the nozzle 3 is attached to the tip thereof.

다수의 증류파이프(12a)는 증류층(12)을 형성하기 위해 결합시 증류파이프(12a)에 뚫은 구멍(12b)이 지그재그형상이 되도록 결합한다.The plurality of distillation pipes 12a are combined to form a zig-zag hole 12b drilled in the distillation pipe 12a at the time of bonding to form the distillation layer 12.

진공탱크(2)의 상부에 연통설치한 흡기 파이프(20)는 공기 응축기(4)를 지나 배출탱크(5)에 연결하며, 배출탱크(5) 상부와 진공펌프(6)에 연결되게 배출파이프(21)를 연결하여 배출가스를 냉각 응축한 후 배출되지 않은 가스를 다시 진공펌프(6)로 대기중으로 배출시키는 것이다.The intake pipe 20 communicating with the upper portion of the vacuum tank 2 is connected to the discharge tank 5 through the air condenser 4, and discharge pipe connected to the upper portion of the discharge tank 5 and the vacuum pump 6 (21) by connecting and cooling the condensation of the exhaust gas and the gas not discharged again to the vacuum pump (6) to the atmosphere.

또한 노즐(3)로 공급된 폐오일은 다수의 지그재그구멍(12b)으로 강하되어서 진공탱크(2)에 저장되어 증류 처리되어져서 진공탱크(2)의 하단측면 파이프에 펌프(7)를 연결 설치하고 이 펌프(7)를 지난 폐오일이 파이프를 통해서 탱크(8)에 연결 설치한다.In addition, the waste oil supplied to the nozzle 3 is dropped into a plurality of zig-zag holes 12b, stored in the vacuum tank 2, and distilled to connect the pump 7 to the pipe at the bottom side of the vacuum tank 2. The waste oil passing through the pump 7 is connected to the tank 8 through a pipe.

그리고, 이 탱크(8)내에는 +전극판(9)과 -전극판(9a)를 고정하여 직류의 고전압을 직류고전압발생장치(11)로 인가하게 하고, 이에 따른 전류공급으로 코로나 방전층(10)을 형성하도록 하여 오염입자가 이동 흡착시키게 하였다.In this tank 8, the positive electrode plate 9 and the negative electrode plate 9a are fixed so that a high voltage of direct current is applied to the direct current high voltage generator 11, and according to the current supply, the corona discharge layer ( 10) was formed so that the polluted particles were transported and adsorbed.

이와 같이 된 본 발명에 있어 오일흡입펌프(1)로 가열된 폐오일을 흡입 유입파이프(3a)로 이송하여 진공탱크내에 투입한다.In the present invention as described above, the waste oil heated by the oil suction pump 1 is transferred to the suction inlet pipe 3a and put into the vacuum tank.

이렇게 투입되는 폐오일을 진공내에서 증류효과를 증대시키기 위하여 노즐(3)을 통해 스프레이 시키면 진공내에서 유체는 비등점이 강하되어 상온에서도 증류되는 성질을 이용 폐오일 내의 유동성 오염물질(수번, 수지성물질, 산화물, 가스등)은 증류층(12)을 거치는 동안 증류되어 진공펌프(6)에 의하여 대기중으로 배출된다.When the waste oil injected in this way is sprayed through the nozzle 3 to increase the distillation effect in the vacuum, the fluid has a boiling point drop in the vacuum and is distilled even at room temperature. Materials, oxides, gases, etc.) are distilled during the distillation layer 12 and discharged into the atmosphere by the vacuum pump 6.

이때 증류층(12)을 거치는 폐오일은 증류 파이프(12a)의 구멍(12b)이 지그재그형으로 되게 배치하여 조립되어서 이 증류파이프(12a)의 구멍(12b) 사이사이를 통과하여 오염물질이 증류 상승되면서 내려가며, 지그재그로 강하되는 유동성 오염물질은 진공탱크(2)의 상부로 증류되어 모이게 된다.At this time, the waste oil passing through the distillation layer 12 is assembled by arranging the holes 12b of the distillation pipe 12a in a zigzag shape and passing through the holes 12b of the distillation pipe 12a to distill the contaminants. Ascending and descending, the zigzag fluid contaminants are distilled and collected at the top of the vacuum tank (2).

이렇게 폐오일이 증류파이프(12a)의 지그재그의 구멍(12b)들을 타고 내려가 진공탱크(2) 아래로 흘러서, 이 흐르는 시간이 길수록 폐오일의 증발시간을 연장함으로 폐오일중의 수분, 수지성물질, 산화물, 가스등을 증류하게 되는 것이다.Thus, the waste oil flows down the zigzag holes 12b of the distillation pipe 12a and flows down the vacuum tank 2 so that the longer the flow time, the longer the evaporation time of the waste oil. Oxides, gases, etc. will be distilled off.

본 발명의 진공탱크(2) 상측에 모인 배출가스는 공기응축기(4)에서 냉각시켜 응축한 후 배출탱크(5)에 저장하고, 일정량이 배출탱크(5)내에 차면 하부의 배출밸브(22)를 통해 드레인 시키어서 폐수처리 설비로 이동시킨다.The exhaust gas collected on the upper side of the vacuum tank 2 of the present invention is cooled in the air condenser 4, condensed, and then stored in the discharge tank 5, and a certain amount is filled in the discharge tank 5 at the lower discharge valve 22. Drain through and transfer to wastewater treatment plant.

상기의 진공펌프(6)는 60~70mmHG의 진공도를 유지하는 것이 가장 바람직하다.Most preferably, the vacuum pump 6 maintains a vacuum degree of 60 to 70 mmHG.

또한 배출탱크(5)내에서 응축되지 않는 배출가스는 진공펌프(6)을 작동시키어 줌으로 대기중으로 배출되어 폐오일중의 유동성 오염물질을 1차적으로 제거한다.In addition, the exhaust gas that does not condense in the discharge tank 5 is discharged into the atmosphere by operating the vacuum pump 6 to primarily remove the fluid pollutants in the waste oil.

폐오일이 진공탱크(2) 상부노즐(3)로 분사되어 증류층(12)을 거쳐 상승되는 유동성 오염물질의 증류된 배출가스는 공기응축기(2)와 배출탱크(5)를 거치는 과정에서 유동성이 제거되어 환경오염의 배출가스가 정화되어 대기에 배출하게 하는 것이다.The distilled exhaust gas of the fluid pollutant, in which the waste oil is injected into the upper nozzle 3 of the vacuum tank 2 and rises through the distillation layer 12, is flowed through the air condenser 2 and the discharge tank 5. This is to remove the exhaust gas of environmental pollution to be discharged to the atmosphere.

그리고 진공탱크(2)의 증류층(12)을 통과한 폐오일은 진공탱크(2) 내에서 저장되고 일정량이 차게 되면 일측면 파이프의 펌프(7)에 의하여 이송시키어서 직류 고전압이 흐르게 장치한 탱크(8)내로 폐오일을 투입시킨다.The waste oil which has passed through the distillation layer 12 of the vacuum tank 2 is stored in the vacuum tank 2, and when a certain amount is filled, the waste oil is transferred by the pump 7 of one side pipe so that the DC high voltage flows. Waste oil is introduced into the tank (8).

이상태에서 10,000V~25,000V를 가진 직류고전압발생장치(11)로 탱크(8)내의 +전극판(9) 및 -전극판(9a)을 인가시키면 높은 전위차를 갖게 되고, 코로나 방전층(10)을 형성하게 된다.In this state, when the + electrode plate 9 and -electrode plate 9a in the tank 8 are applied to the DC high voltage generator 11 having 10,000V to 25,000V, the potential difference is high, and the corona discharge layer 10 is applied. Will form.

이때, 투입된 폐오일이 코로나 방전층(10)을 통과하는 동안 폐오일내의 오염물질은 각기 고유의 성질에 따라 표면에 +, -로 대전되고, 쿨롱의 힘에 의하여 대전된 반대극성의 전극판에 이동 흡착되어 제거되고, 흡착된 오염입자는 첨예한 부분을 형성하여 전류를 집중시키고, 흡착 작용을 상승시켜 오염물질 제거 효과를 배가시키게 된다.At this time, while the injected waste oil passes through the corona discharge layer 10, the contaminants in the waste oil are charged with + and-on the surface according to their inherent properties, and are charged to the opposite polarity electrode plate by the coulomb force. The mobile adsorbed and removed, the adsorbed contaminated particles form a sharp portion to concentrate the current, increase the adsorption action to double the pollutant removal effect.

이와 같이 사용되는 +전극판(9) 및 -전극판(9a)에 오염물질이 많이 흡착되어 더러워지게 되면 탱크(8)내에 설치되는 미도시된 감지기의 작동에 의해 외부에서 전류의 흐름을 알 수 있어 각 전극판을 교체하여 줌으로써 항상 동일한 청정도의 오일을 재생처리있게 하였다.When a lot of pollutants are adsorbed on the + electrode plate 9 and the-electrode plate 9a used in this way and become dirty, the current flow can be seen from the outside by the operation of a detector not shown in the tank 8. The replacement of each electrode plate ensures that oil of the same cleanliness is always regenerated.

본 발명의 직류전압이 인가된 탱크(8)내의 코로나 방전층(10)을 통과한 폐오일은 신유와 같은 맑고 투명한 오일로 재생되어 배출밸브(23)를 통해 재생유 탱크(24)로 배출시켜 재활용이 가능한 것이다.Waste oil passing through the corona discharge layer 10 in the tank (8) to which the DC voltage of the present invention is applied is regenerated into a clear and transparent oil such as fresh oil and discharged to the regeneration oil tank (24) through the discharge valve (23). It can be recycled.
