본 고안은 공장이나 사진 현상소 등과 같이 화학약품이나 각증 이물질이 포함되어 배출시키는 폐수를 응집제의 첨가없이 처리하는 전공 증류법에 의한 폐수 처리기에 관한 것으로, 상세하게는 1차 진공증류기에서 어느 정도 수분이 제거된 농축 폐수를 2차 진공증류기로 유입시켜 페수를 가열하도록 하여 열손실을 최대한 줄이면서 폐수를 재활용 할 수 있도록 한 폐수 처리기에 관한 것이다.The present invention relates to a wastewater treatment system by a major distillation process that treats wastewater containing chemicals or other foreign substances, such as factories or photo labs, without the addition of a flocculant. The present invention relates to a wastewater treatment system that allows the wastewater to be heated by introducing the concentrated wastewater into a secondary vacuum distillation, thereby minimizing heat loss and recycling the wastewater.
일반적으로 폐수를 치리하는 방법은 응집제를 폐수 내에 침투시켜 응집제가 폐수에 포함되어 있는 이물질을 응집시키는 화학적 처리방법과 미생물을 이용한 생물학적 처리방법 및 기계장치를 이용하여 여과하는 방법, 그리고 폐수를 증류시켜 여과하는 방법이 있는 것이다.In general, the method of controlling wastewater includes a chemical treatment method in which a coagulant penetrates into the waste water to coagulate foreign substances contained in the waste water, a biological treatment method using microorganisms, a filtration method using a mechanical device, and distillation of the waste water. There is a way to filter.
본 고안은 네 가지의 실예중 진공상태의 저온 중발에 의한 처리방법에 관한 것으로 폐수중에 수용성인 소금이나 망초성분과 고농도 COD, BOD 폐수는 타처리 방법으로는 거의 불가능한 실정이며 본 처리기는 증류효과를 증대시키고 여과 효율을 극대화 시켜 어떠한 난처리 폐수도 처리할 수 있게 고안한 것이다.The present invention relates to a treatment method by low temperature heavy-duty vacuum in four examples. Soluble salt or forget-me-not, high concentration COD, and BOD wastewater in waste water are almost impossible with other treatment methods. It is designed to treat any untreated wastewater by increasing and maximizing filtration efficiency.
이하 종래의 증류법에 의한 폐액 처리방법에 대한 설명을 실용신안공고 제81-1419호를 인용하여 개략적으로 설명하면, 이건 증류법에 의한 폐액 처리방법은 저장조의 폐액을 하단에 열교환기가 설치되고 상단에 1차수 분리기가 설치된 증류기로 이송한 다음 100-105℃로 가열시켜 증발되는 수증기와 이에 수반되는 악취성 가스가 자체의 발생압력에 의하여 증류기 내의 상단에 설치된 1차수 분리기를 통과하도록 한 후에 증류기 외부에 설치된 2차수 분리기를 경유하여 응축기로 유입되어 살수되는 냉각수에 의해 냉각응축되어 여과조를 통해 배출 처리되고 불순물은 증류기의 최하단부에서 고농도로 농축된 후에 배출되어 응결 처리하도록 된 장치이나, 이와 같이 처리된 종래의 방법은 본인이 특허권에 대해 지분 양도받아 사용하여 보니 상기의 결함을 갖는 것이다.Hereinafter, a description of the conventional waste liquid treatment method by distillation method will be described briefly by citing Utility Model Publication No. 81-1419, which is a waste liquid treatment method by distillation method. It is transferred to a still separator equipped with a degree separator and heated to 100-105 ° C. to allow evaporated water vapor and accompanying odorous gas to pass through the primary separator installed at the top of the still part by its generated pressure. The apparatus is condensed by cooling water flowing into the condenser through the secondary water separator and sprinkled and discharged through a filtration tank, and impurities are concentrated and concentrated at the bottom of the distillation at the bottom of the still, and discharged to condense. The method is that I owned a stake in a patent and used it. It is.
즉, 증류기 내에서 처리수를 가열하는데 많은 연료소모가 소비되는 결함과 악취가 정화되지 않은 상태로 배출되어 주위환경을 오염시키는 결함 및 스러지가 완전 고형화가 되지 않는 결함과 정화능력이 완전하지 못한 결함이 발생하는 것이다.In other words, defects that consume a lot of fuel consumption to heat the treated water in the still, the odor is discharged unpurified and pollutes the surrounding environment, defects that do not completely solidify the sludge and incomplete purification ability This is what happens.
본 고안인은 상기의 결함을 해결하기 위하여 증류기를 진공화하여 저온에서도 수분이 증발되도록 하여 처리된 수질이 양호하도록 1차 연료소비를 줄이고 폐수가 증류기로 이송되기 전에 가열기를 통과하도록 함으로서 폐수가 가열된 상태로 진공증류기로 이송되고 진공증류기 내에서 분사될매 가열관에 의해 가열되기 때문에 가열시간을 짧게 하여 연료소비를 최대한 줄일수 있도록 한 특허를 국내 특허 제92-26044호로 제공한 바 있으나, 이 발명은 진공 증발기에서만 폐수를 처리하도록 되어 있어서 폐수를 처리하는데 폐수가 고농축되면 가연 튜브에 스케일이 끼고 처리효율이 저하되는 등 그 한계점이 있는 것이며, 폐수를 드럼 건조기로 가열하여 건조시켜 정화하는 장치를 실용신안 등록 출원 제92-27219호로 제공하였으나, 이 고안 역시 평면 드럼 건조기로 유입되는 폐수를 가열하여 증발 시키는데에 많은 시간이 소요되어 에너지 손실의 낭비를 초래하게 되는 결합이 있는 것이다.In order to solve the above deficiency, the present inventors evacuated the distiller to allow the water to evaporate even at low temperatures, thereby reducing the primary fuel consumption so that the treated water quality is good and allowing the waste water to pass through the heater before the waste water is transferred to the distiller. Patent No. 92-26044 has been provided to reduce the fuel consumption by shortening the heating time since it is transferred to the vacuum distillation and heated by each heating tube to be injected in the vacuum distillation. The present invention is to treat the waste water only in the vacuum evaporator, and the waste water is treated, but when the waste water is highly concentrated, the scale of the combustible tube is reduced and the treatment efficiency is reduced. Utility Model Registration Application No. 92-27219, but this design is also a flat drum gun There is a bond that takes a long time to heat and evaporate the wastewater that enters prematurely, resulting in a waste of energy loss.
본 고안인은 상기의 결함을 해결하기 위하여 고안한 것으로, 드럼 건조기와 진공증류기, 히터펌프 그리고 응축기와 가열기를 서로 일련 불가분하게 결합 구성하여 폐수자체의 폐열과 가열할때의 열을 순환시켜 유입되는 폐수를 가열하도록 함으로서 에너지의 손실을 최대한 억제하도록 한 것이다.The present inventors have devised to solve the above defects, the drum dryer, vacuum distillation unit, heater pump, condenser and heater are inseparably combined with each other to circulate the waste heat of the waste water itself and the heat during heating By heating the waste water, the loss of energy is minimized.
이하 본 고안을 첨부된 도면에 따라 상세히 설명하면, 공급펌프(P1)에 의해 강제 흡입된 폐수가 열교환기(1)를 통과한 후 진공증류기(2)로 유입되어 분사관(4)으로 분사되고 진공증류기(2)의 하부 폐수는 센서(S3)(S4)가 감지하여 1차 순환펌프(P2)와 농축펌프(P3)에 의해 2차 진공증류기(3)의 분사관(5)으로 분사하게 되는 것이며 진공증류기(3)로 분사되는 폐수는 열매체유 보일러(B)에서 공급되는 열에 의해 가열된 열판(6)을 통과하면서 일부는 증기로 변하고 일부는 바닥에 차이게 되는 것이다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings, and the wastewater forcedly sucked by the supply pump P 1 passes through the heat exchanger 1 and then flows into the vacuum distillation unit 2 to be injected into the injection pipe 4. The lower wastewater of the vacuum distillation unit 2 is detected by the sensor S 3 and S 4 , and the injection pipe of the secondary vacuum distillation unit 3 is formed by the primary circulation pump P 2 and the concentration pump P 3 . 5) and the waste water sprayed into the vacuum distillation unit 3 passes through the hot plate 6 heated by the heat supplied from the heat medium oil boiler B, and part of the waste water is changed into steam and part of the waste water is different from the bottom. .
즉, 순환식 열매체유 보일러(B)에서 가열되어 이송되어온 증류가 열판(6)을 가열하게 되고 열판(6)을 가열한 증류는 배출관(6A)에 의해 열매체 보일러(B)로 재순환되고 열판(6)은 가열된 상태에서 진공증류기(3)로 유입되어 열판(6)을 통과하는 폐수를 증발시키게 되는 것이다.That is, the distillation heated and transported in the circulating heat medium oil boiler B heats the hot plate 6, and the distillation heated the hot plate 6 is recycled to the heat medium boiler B by the discharge pipe 6A and the hot plate ( 6) is to evaporate the wastewater flowing into the vacuum distillation unit (3) in the heated state and passing through the hot plate (6).
열판(6)에 의해 증발된 증류와 진공증류기(3)의 바닥에 차여 있다가 열판(6)에 의해 점차 증발하게 된 폐수는 히터 펌프(P6)의 흡입력에 의해 1차 진공증류기(2)의 가열관(9)을 가열하는 열매체로 사용되는 것이며 진공증류기(3)에서 증발하지 못한 폐수는 센서(S1)에 의해 수위를 체크하여 순환펌프(P4)가 이를 감지하여 진공증류기(3)의 분사관(5)으로 재순환 시키는 것이다.The distillation evaporated by the hot plate 6 and the bottom of the vacuum distillation machine 3 which are gradually evaporated by the hot plate 6 are discharged by the suction power of the heater pump P 6 . It is used as a heating medium for heating the heating tube (9) of the waste water that does not evaporate in the vacuum distillation unit (3) by checking the water level by the sensor (S 1 ) by the circulation pump (P 4 ) detects this and the vacuum distillation unit (3) Recycle to the injection tube (5).
이와 같은 상태가 반복되다가 센서(S2)가 최저수위를 체크하여 순환되는 밸브(V2)를 차단하고 밸브(V3)(V1)를열어 외부로 배출하는 것이다. 즉 진공증류기(3)의 폐수를 순환시키고자 할 경우 펌프(P4)가 가동되는 상태에서 밸브(V1)(V2)를 열고 밸브(V3)는 차단하여 배출되지 못하게 하여 순환하고 폐수가 최저수위를 나타내면 폐수는 수분이 거의 증발하여 묽은 반죽상태로 되는 것으로 이때에는 밸브(V2)를 차단하고 밸브(V3)를 열어 외부로 배출하는 것이다.This condition is repeated, the sensor (S 2 ) checks the lowest water level to shut off the valve (V 2 ) circulated and open the valve (V 3 ) (V 1 ) to discharge to the outside. That is, in order to circulate the waste water of the vacuum distillation machine 3, the valve V 1 and V 2 are opened while the pump P 4 is operated, and the valve V 3 is blocked to prevent the discharge and circulate and the waste water is discharged. When the lowest water level indicates the waste water, the water is almost evaporated to form a thin dough. In this case, the valve V 2 is shut off and the valve V 3 is opened and discharged to the outside.
이후 진공증류기(3)에서 가열된 수증기는 히터펌프(P5)에 의해 진공증류기(2)로 공급되어 진공증류기의 가열관(9)을 가열하는 것으로 가열관(9)을 가열하고 배출되는 증기는 분사되는 폐수에 의해 냉각되어 응축수로 변하게되는 것이며, 응축수는 펌프(P6)에 의해 강제로 열교환기(1)로 유입되어 공급펌프(P1)에 의해 열교환기(l)로 유입되어지는 폐수를 가열하면서 완전히 열을 빼앗긴 상태로 배출되어 각종 산업수로 재사용 하는 것이다.Thereafter, the steam heated in the vacuum distillation unit 3 is supplied to the vacuum distillation unit 2 by the heater pump P 5 to heat the heating tube 9 of the vacuum distillation unit to heat the heating tube 9 and discharge the steam. Is cooled by the injected waste water and is converted into condensate. The condensate is forced into the heat exchanger 1 by the pump P 6 , and is introduced into the heat exchanger 1 by the feed pump P 1 . The waste water is discharged while being completely deprived of heat while being reused as various industrial waters.
또한, 진공증류기의 가열관(9)으로 분사되는 폐수는 가열관(9)에 의해 가열되면서 하부에 차이게 되고, 이때 발생되는 열기는 히터펌프(P5)에 의해 순환되어 가열관(9) 내부로 이송되면서 가열관을 더욱 가열할 수 있도록한 것이다.In addition, the waste water injected into the heating tube 9 of the vacuum distillation unit is heated by the heating tube 9 to be lowered, and the heat generated is circulated by the heater pump P 5 to heat the heating tube 9. As it is transported inside, the heating tube can be heated more.
상기, 호퍼에 차이는 폐수는 공급펌프(P1)에 연결하여 재순환 하고 순환과정 중 진공증류기(3)에 필요한 양 만큼의 농축액이 하부 호퍼에 공급된다.The difference in the hopper is that the waste water is recycled by being connected to the supply pump (P 1 ) and the concentrate is supplied to the lower hopper in an amount necessary for the vacuum distillation unit 3 during the circulation process.
그리고, 본 고안에서 진공증류기(2)(3) 내의 진공을 유지하기 위해서는 진공증류기(2)(3)의 증발된 증류가 냉각되어야 진공 상태를 유지할 수가 있는 것으로 쿨링타워(7)에 의해 냉각수가 순환되는 응축기(8)를 별도 설치하여 진공증류기(2)에서 냉각되지 않은 증류수를 응축기(8)로 보내어 완전냉각할 수 있도록 함으로서 진공증류기(2)(3)의 내부를 완전히 진공할 수 있는 것이며 응축가스가 적을 경우 상부의 밸브(V4)를 개방하여 바로 외부로 배출시키는 것이다.In the present invention, in order to maintain the vacuum in the vacuum distillation unit (2) (3), the cooling water by the cooling tower (7) can maintain the vacuum state when the evaporated distillation of the vacuum distillation unit (2) (3) is cooled. By installing a separate condenser (8) circulating to send the uncooled distilled water from the vacuum distillation (2) to the condenser (8) to be completely cooled, it is possible to completely vacuum the interior of the vacuum distillation (2) (3) If less condensate gas is to open the upper valve (V 4 ) to discharge immediately.
상기, 응축기에서 웅축된 정수는 재차 열 교환기(1)와 펌프(P6)사이로 이송되어져 열교환기(1)를 가열하면서 외부로 배출되어 산업용수로 재 활용할 수가 있는 것으로, 건조물의 제거와 함께 폐수를 증류처리 함으로서 기계 설치비용과 장소 및 에너지 모두를 절약할 수 있는 것이다.The purified water condensed in the condenser is again transferred between the heat exchanger 1 and the pump P 6 to be discharged to the outside while heating the heat exchanger 1 to be reused as industrial water. Distillation can save both the installation cost and the location and energy.
