Specifically, the wastewater is injected into a vacuum evaporator through a heat exchanger. In the vacuum evaporator, the distilled water which is heated and heated by the heating wire in the vacuum evaporator is passed again through the heating tube installed inside the vacuum evaporator, and then flowed into the cooler so that the condensate is cooled and condensed in the cooler. A small amount of condensate was introduced into the filter tower so that only clean air without odor was discharged to the outside.

일반적으로 폐수를 처리하는 방법은 응집제를 폐수 내에 침투시켜 응집제가 폐수에 포함되어 있는 이물질을 응집시키는 방법과 기계장치를 이용하여 여과하는 방법 그리고 폐수를 증류시켜 여과하는 방법이 있는 것이다.In general, wastewater treatment methods include a method of infiltrating a flocculant into the wastewater to agglomerate foreign matter contained in the wastewater, a method of filtering using a mechanical device, and a method of distilling and filtering the wastewater.

본 발명은 세가지의 실예중 진공상태의 저온 증발에 의한 처리방법에 관한 것으로 증류효과를 증대시키고 여과효율을 극대화 시키도록 개발한 것이다.The present invention relates to a treatment method by low temperature evaporation in a vacuum state among three examples and has been developed to increase the distillation effect and maximize the 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°C로 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, 이와같이 처리된 종래의 방법은 본인이 특허권에 대해 지분 양도받아 사용하여 보니 하기의 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. Transfer to a still separator installed and then heated to 100-105 ° C to allow evaporated water vapor and accompanying malodorous gas to pass through the primary separator installed at the top of the still by the pressure of its own Apparatus for cooling and condensing by cooling water flowing into condenser through installed secondary water separator and being discharged through filtration tank, and impurity is concentrated in high concentration at the bottom of the distiller and then discharged and condensed. The method has the following flaws Will.

즉, 증류기 내에서 처리수를 가열하는데 많은 연료소모가 소비되는 결함과 악취가 정화되지 않은 상태로 배출되어 주위환경을 오염시키는 결함과 정화능력이 완전하지 못한 결함이 발생하는 것이다.That is, defects in which a large amount of fuel consumption is consumed in heating the treated water in the still, and odors are discharged without purification, resulting in defects contaminating the surrounding environment and defects in which the purification ability is not perfect.

본 발명인은 상기의 결함을 해결하기 위하여 개발한 것으로서 증류기를 진공화하여 저온에서도 수분이 증발되도록 하여 처리된 수질이 양호하도록 1차 연료소비를 줄이고 폐수가 증류기로 이송되기 전에 가열기를 통과하도록 함으로서 폐수가 가열된 상태로 진공증류기로 이송되고 진공증류기내에서 분사될 때 가열관에 의해 가열되기 때문에 가열시간을 짧게 하여 연료소비를 최대한 줄일 수 있도록 한 것이다.The inventors of the present invention have developed to solve the above deficiency, by evacuating the distiller to allow the water to evaporate even at low temperatures, reducing the primary fuel consumption so that the treated water quality is good and passing the heater through the heater before the waste water is transferred to the distiller. Is heated to a vacuum distillation in a heated state and is heated by a heating tube when injected into the vacuum distillation, so that the heating time is shortened to minimize fuel consumption.

이하 본 발명을 첨두된 도면에 따라 상세히 설명하면, 폐수저장조(1)의 폐수를 펌프(P1)로 응축기(2)를 통과하도록 한 다음 통과하여 1차 가열된 폐수를 진공증발기(3)의 하부로 유입하여 2차 가열한 다음 진공증발기(3)의 하부에 있는 폐수는 펌프(P2)로 분사관(4)으로 이송시켜 분사되게 구성하고 분사관(4)의 하부에는 가열관(6)을 설치하여 분사되는 폐수가 3차 가열되도록 한 다음 진공증발기(3)의 하부에 설치된 열교환화기(5)에 의해 분사관(4)을 통해 유입되는 폐수를 가열하여 증발시킨다.DETAILED DESCRIPTION Hereinafter, the present invention will be described in detail with reference to the accompanying drawings, and the wastewater of the wastewater storage tank 1 is passed through the condenser 2 with a pump P 1 , and then the first heated wastewater is passed through the vacuum evaporator 3. The waste water in the lower part of the vacuum evaporator (3) after flowing into the lower part is transferred to the injection pipe (4) by the pump (P 2 ) so that the injection is carried out, and the heating pipe (6) at the bottom of the injection pipe (4). The wastewater to be injected is heated to the third by heating, and then the wastewater introduced through the injection pipe 4 is heated and evaporated by the heat exchanger 5 installed under the vacuum evaporator 3.

이때 증발기(3)는 진공상태에 있기 때문에 비등점이 낮게 되어 진공상태가 아닌 증류기에 비해 현저히 적은 비열로 폐수를 가열하여 증발시킬 수 있는 것이며 더욱이 폐수가 진공증발기(3)로 유입되기 전에 응축기(2)와 증발관(6)을 통과하여 폐수가 가열된 상태로 되기 때문에 가열되어 증발된 수분은 진공브로아(P3)를 이용하여 강제 흡입하여 진공증발기(3)의 증발관(6)을 통과하여 열교환기(5)의 스팀유입관(5´)과 증발관(6)의 선단(6')과 연결된 연결관(6˝)을 통해 유입되는 스팀과 혼합되어 증발관(6)을 가열시킨 후 응축기(2)로 유입시켜 응축기(2)에서 폐수에 의해 온도가 낮아진 증기가 물로 변화하게 되는 것이며 물로 변한 응축수는 펌프(P4)로 처리수탱크(7)로 보내지고 물로 변화하지 못한 공기는 펌프(P5)를 이용 흡착기(8)로 이송하여 공기중에 포함된 냄새나 이물질을 걸러서 대기중으로 깨끗한 공기만을 배출시키는 것이다.At this time, since the evaporator 3 is in a vacuum state, the boiling point is low, so that the waste water can be evaporated by heating the waste water with a significantly lower specific heat than the distillator, which is not in the vacuum state. ) And the waste water is heated by passing through the evaporation tube (6), the moisture evaporated by heating is forced to suck using the vacuum broa (P 3 ) and passes through the evaporation tube (6) of the vacuum evaporator (3). After the steam inlet pipe 5 ′ of the heat exchanger 5 and the steam introduced through the connecting pipe 6 ′ connected to the tip 6 ′ of the evaporation tube 6 are mixed to heat the evaporation tube 6. Steam entering the condenser (2) is lowered by the waste water in the condenser (2) is converted to water, the condensate is turned into a water pump (P 4 ) to the treated water tank (7) and the air that did not change into water to feed the pump (P 5) by using an adsorber (8) included in the air That is to smell and filtering foreign matter discharge only clean air into the atmosphere.

특히 응측기(2)에서 증기를 냉각시킬때 냉각수를 폐수로 사용함으로서 응축기(2)를 동작시키는데 소모되는 에너지와 폐수를 가열하는데 소모되는 에너지를 절약할 수가 있는 것이며 진공증발기(3)의 하부에는 농축수 저장조(9)를 설치하여 펌프(P4)로 진공증발기(3) 하부에 쌓이는 농축수를 배출시킬 수 있도록 한 것이다. 도면중 미설명부호 10은 진공증발기(3)의 내부 상측에 설치되는 여과망이다.In particular, when cooling the steam in the condenser (2) by using the cooling water as the waste water it is possible to save the energy consumed to operate the condenser (2) and the energy used to heat the waste water and the lower part of the vacuum evaporator (3) The concentrated water storage tank 9 is installed to discharge the concentrated water accumulated under the vacuum evaporator 3 by the pump P 4 . In the figure, reference numeral 10 is a filter net installed on the upper side of the vacuum evaporator 3.

상기와 같은 본 발명의 동작상태를 설명하면, 폐수저장조(1)에 담겨 있는 폐수는 펌프(P1)에 의해 응축기(2)로 공급되며 일정온도 가열되며 펌프(P2)로 진공증발기(3)로 공급시키는데 이때 응축기(2)의 공급열원은 진공증발기(3)에서 증기로 변환한 수분이 응축기(2)를 통과하도록 하여 폐수가 증기의 수분을 식히면서 폐수의 온도를 상승시키는 것이어서 폐수를 가열하는데 소모되는 에너지는 절약하는 것이다.Referring to the operation of the present invention as described above, the wastewater contained in the wastewater storage tank (1) is supplied to the condenser (2) by the pump (P 1 ) and is heated to a constant temperature and the vacuum evaporator (3) to the pump (P 2 ) At this time, the supply heat source of the condenser (2) is to allow the moisture converted into steam from the vacuum evaporator (3) to pass through the condenser (2) to increase the temperature of the waste water while cooling the water of the steam to heat the waste water. The energy consumed to do so is to save.

상기 진공증발기(3)로 공급된 폐수는 분사관(4)을 통해 분사공급시키는데 증발기(3)가 진공상태에 있고 1차 응축기(2)에 의해 가열되고 2차 열교환기(5)에 의해 더욱 가열된 상태로 증발관(6)으로 분사되기 때문에 쉽게 폐수내의 수분이 증발되는 것이며 증발되지 못한 폐수는 열교환기(5)로 이송되어 열교환기(5)에서 계속 가열되어 증발되는 것이다.The wastewater supplied to the vacuum evaporator 3 is injected and supplied through the injection tube 4, in which the evaporator 3 is in a vacuum state and is heated by the primary condenser 2 and further by the secondary heat exchanger 5. The water in the wastewater is easily evaporated because it is injected into the evaporation tube 6 in a heated state, and the wastewater that has not been evaporated is transferred to the heat exchanger 5 and continuously heated and evaporated in the heat exchanger 5.

상기와 같이 진공증발기의 폐수를 펌프(P2)로 계속 순환시키도록 함으로서 폐수내의 폐수는 계속 증발하게 되는 것이며 이 물질보다 비등점이 낮은 수분은 가열되어 증발하게 되고 증발된 수분은 펌프(P3)로 응축기(2)로 공급시키고 증발하지 못한 이물질은 진공증발기(3)의 하부에 쌓이게 되면 이를 펌프(P6)로 농축수 저장조(9)로 배출하여 처리하는 것이다.By continuing to circulate the wastewater of the vacuum evaporator to the pump (P 2 ) as described above, the wastewater in the wastewater continues to evaporate, and the water having a boiling point lower than this substance is heated and evaporated, and the evaporated water is pumped (P 3 ). When the foreign matter that is not supplied to the condenser 2 and does not evaporate is accumulated in the lower part of the vacuum evaporator 3, it is discharged to the concentrated water storage tank 9 by a pump P 6 and treated.

열교환기(5)에서 증발된 수분은 응축기(2)로 이송되기 전에 진공브로아(P3)로 흡입된 증기가 재차 진공증발기(3)의 하부에 설치한 증발관(6)을 통과하도록 하여 열교환기(5)의 스팀과 함께 증발관(6)을 가열한후 응축기(2)로 공급되도록 한 것이다.Moisture evaporated from the heat exchanger (5) is passed through the evaporation tube (6) installed in the lower part of the vacuum evaporator (3) to the steam sucked into the vacuum blower (P 3 ) before being transferred to the condenser (2) The evaporation tube 6 is heated together with the steam of the group 5 to be supplied to the condenser 2.

응축기(2)로 공급된 증기를 폐수에 의해 열을 빼앗겨 물로 변하게 되며 물로 변한 정화된 물은 탱크(7)로 이송되고 증기속에 포함되어 있던 악취나 공기는 진공펌프(P5)에 의해 흡착기(8)로 이송시켜 탈취한 다음 정화된 공기만 배출시키고 가스속에 포함된 수분은 재차 흡착기에서 여과망에 의해 물로 변화시켜 물로 변한 수분은 연결관(7')에 의해 처리수 탱크(7)로 이송되도록 하는 것이다.The steam supplied to the condenser (2) is converted into water by being deprived of heat by wastewater, and the purified water converted into water is transferred to the tank (7), and the odor or air contained in the steam is absorbed by the vacuum pump (P 5 ). 8) and then deodorized and discharged only the purified air, and the water contained in the gas is changed into water by the filter network again in the adsorber, and the water converted into water is transferred to the treated water tank 7 by the connecting pipe 7 '. It is.

이때 응축기(2)로 유입된 증발수는 폐수를 가열하면서 응축되는 것으로 증발수에 의해 가열된 폐수는 온수상태로 진공증발기로 유입되어 열교환기(5)가 적은 열량으로 폐수를 가열할 수 있는 것이며 가열된 폐수를 분사관(4)에서 분사될 때 증기에 의해 가열된 증발관(6)에 의해 더욱 가열시킬수 있는 것이며 이와같은 상태에서 재차 열교환기(5)로 가열하도록 함으로서 에너지의 손실을 최대한 억제할 수 있는 것이며 대기중으로 악취 및 공해의 배출을 방지하는 폐수정화 능력을 배가시킬 수 있도록 한 것이다.At this time, the evaporated water introduced into the condenser 2 is condensed by heating the waste water. The waste water heated by the evaporated water is introduced into the vacuum evaporator in a hot water state so that the heat exchanger 5 can heat the waste water with a small amount of heat. The heated wastewater can be further heated by the evaporation tube 6 heated by steam when it is injected from the injection tube 4, and in such a state, it is possible to heat the heat exchanger 5 again to minimize the loss of energy. It is possible to double the wastewater purification capacity to prevent the release of odors and pollution into the atmosphere.
