Description

진공증발 농축기 {Vacuum vapor compression concentrator}Vacuum vapor condenser {Vacuum vapor compression concentrator}

본 발명은 진공증발 농축기에 관한 것으로, 보다 상세하게는 일정한 목적에 사용된 후 오염된 물, 기름 등과 같은 폐액을 재생하기 위한 진공증발 농축기에 관한 것이다.The present invention relates to a vacuum evaporator, and more particularly, to a vacuum evaporator for regenerating waste liquid such as contaminated water, oil and the like after being used for a certain purpose.

산업화의 발달로 각종부품제조공장은 물론 식품가공공장, 반도체공장 등과 같이 다양한 산업분야 전반에서 자동화생산라인 구축으로 생산성 제조원가는 절감하면서 우수한 품질의 제품을 대량생산하고 있지만, 생산설비의 자동화와 함께 각각의 공정에 세척, 염색, 식품가공 등의 용도로 사용되는 물, 기름등의 사용량도 함께 증가되어 폐액(불순물이 포함된 오염된 액체) 발생량이 해마다 증가하는 추세이다.Due to the development of industrialization, the production of high-quality products while reducing productivity and manufacturing cost by mass production of automated production lines in various parts of industries such as food processing plant, semiconductor factory, etc. The amount of water and oil used for washing, dyeing, food processing, etc. is also increased in the process, and the amount of waste liquid (contaminated liquid containing impurities) is increasing every year.

이에, 폐액이 발생되는 대부분의 제조공장에서는 필히 자사에서 발생되는 폐액을 수거하거나 정제하기 위한 시설을 함께 갖추어야 하지만, 설비투자에 따른 비용부담으로 인해 설치를 꺼리거나 폐액처리설비을 시공하더라도 지속적으로 발생되는 유지관리비에 따른 제정악화를 이기지 못하고 도산하는 경우가 허다하게 발생된다.Therefore, most manufacturing plants that generate waste liquids must be equipped with facilities for collecting or refining waste liquids generated by the company, but they are continuously generated even if they are reluctant to install or construct waste liquid treatment facilities due to the cost of facility investment. There are many cases where bankruptcy fails to overcome the deterioration caused by maintenance costs.

이에 따라, 종래에 등록실용신안 제20-0384132호(명칭: 폐액 재생장치)에서 이미 사용된 폐액을 증류조 내에서 비등점 이상으로 가열시켜 열분해 한 다음 기화시키고, 기화된 폐액은 응축시켜 액화한 다음 용기에 저장하였다가 재(再)사용하거나 또는 세척조로 보내 재(再)사용할 수 있으므로 자원을 절약하고 환경오염을 방지하기 위한 기술이 선등록된바 있지만, 상기한 기술은 설비를 시공후 가동함에 있어 다음과 같은 많은 문제점이 제기되었다.Accordingly, the waste liquid previously used in the registered utility model No. 20-0384132 (name: waste liquid regeneration device) is thermally decomposed and heated in a distillation tank above the boiling point, and then vaporized, and the vaporized waste liquid is condensed and liquefied. The technology for saving resources and preventing environmental pollution has been pre-registered because it can be stored in a container and reused or sent to a washing tank. There have been many problems raised as follows.

첫째, 폐액을 열분해하기 위해서는 비등점이상으로 가열해야 하므로 폐액 재생에 소요되는 비용부담이 크다. 즉, 폐액이 오염된 물일 경우 대기압상태에서 100℃이상 가열해야 하므로 염색공장에서 하루에 수천톤씩 배출되는 폐액을 단순히 상온에서 열분해방식으로 재생하기에는 무리가 따른다.First, in order to pyrolyze the waste liquid, it must be heated above the boiling point, so the cost of waste liquid regeneration is high. In other words, if the waste liquid is contaminated water, it must be heated to 100 ° C. or higher at atmospheric pressure, so it is difficult to simply recycle the waste liquid discharged thousands of tons per day from the dyeing plant by pyrolysis at room temperature.

둘째, 폐액을 비등점이상으로 가열하기 위해서는 많은 시간이 소요되므로 시간당 처리용량이 저조한 실정이다.Second, it takes a lot of time to heat the waste liquid above the boiling point, so the processing capacity per hour is low.

셋째, 냉각조를 이용하여 기화된 폐액을 1회 냉각후 용기에 보관하므로 기름을 재생할 경우 일부 완전히 냉각되지 않고 기체상태로 존재하는 폐액증기가 용기에 저장시 폭발위험이 있다.Third, since the vaporized waste liquid is stored in the container after cooling once by using a cooling tank, when the oil is regenerated, there is a risk of explosion when the waste liquid vapor, which is present in gaseous state without being completely cooled, is stored in the container.

넷째, 초기에 불순물이 여과되더라도 가열조와 냉각조를 통하여 기화, 응축되는 와중에 슬러지 상태로 불순물이 일부 발생되지만, 이를 여과하기 위한 필터구성이 구비되지 않아 재생액의 순도가 저하되는 문제점이 따랐다.Fourth, even though the impurities are initially filtered, some of the impurities are generated in the sludge state during the evaporation and condensation through the heating and cooling tanks, but there is a problem in that the purity of the regeneration solution is reduced because a filter structure for filtering the impurities is not provided.

본 발명은 상기와 같은 문제점을 해결하고자 안출한 것으로, 폐액을 보다 낮은 비등점에서 기화되도록 구조를 개선하여 폐액 가열에 따른 에너지 절감과 함께 시간당 처리용량이 크게 증가시키고, 또 폐액을 보다 높은 순도의 증류액으로 재생하면서, 재생후 미열로 인한 증발손실 및 폭발을 방지하기 위한 진공증발 농축기를 제공하는 것을 목적으로 한다.The present invention has been made to solve the above problems, by improving the structure to evaporate the waste liquid at a lower boiling point to increase the treatment capacity per hour with energy saving due to the heating of the waste liquid, and further distillate the waste liquid of higher purity It is an object of the present invention to provide a vacuum evaporator to prevent evaporation loss and explosion due to poor heat after regeneration.

이상의 구성 및 작용에 의하면, 본 발명은 증발기 내의 폐액을 감압가열하여 대기압 보다 낮은 기압에서 기화됨에 따라 폐액을 비등점까지 가열시 소요되는 에너지가 크게 절감되고, 특히 1, 2차에 거치면서 폐액증기를 냉각처리하여 잔류열로 인한 폭발이나 증발 손실이 방지되며, 또 예열부가 증발된 폐액증기를 증발기로 인입되는 폐액과 열교환시켜 증기의 보유열을 회수함으로써 열효율이 향상되는 효과가 있다.According to the above configuration and operation, the present invention is greatly reduced the energy required to heat the waste liquid to the boiling point as the waste liquid in the evaporator is heated under reduced pressure to vaporize at a pressure lower than atmospheric pressure, in particular through the first and second waste steam The cooling treatment prevents explosion or evaporation loss due to residual heat, and heat efficiency is improved by recovering heat of steam by exchanging the waste liquid vapor from which the preheater is evaporated with the waste liquid introduced into the evaporator.

또, 증발기와 냉각부를 거쳐 추출된 폐액응축수가 에젝터를 통하여 고압분사되면서 제2필터에 의해 여과됨에 따라 여과처리효율이 향상됨은 물론 기화, 응축작용중에 발생되는 미세한 입자상태의 이물질까지 깨끗하게 제거되는 효과가 있다.In addition, as the waste liquid condensed water extracted through the evaporator and the cooling part is filtered by the second filter while being injected at high pressure through the ejector, the filtration treatment efficiency is improved, and fine particles of foreign matter generated during vaporization and condensation are cleanly removed.

이하, 첨부된 도면을 참조하여 본 발명의 바람직한 실시예를 상세히 설명한다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

도 1은 본 발명에 따른 진공증발 농축기를 전체적으로 나타내는 구성도이고, 도 2는 본 발명에 따른 진공증발 농축기의 감압필터부를 나타내는 구성도이다.1 is a schematic view showing a vacuum evaporator concentrator according to the present invention, Figure 2 is a schematic view showing a vacuum filter of the vacuum evaporator according to the present invention.

본 발명은 진공증발 농축기에 관련되며, 이때 진공증발 농축기는 세정, 염색, 반도체, 식품가공 등의 제조공정에서 발생되는 오염된 폐액을 보다 낮은 비등점에서 기화시켜 증류액으로 추출함은 물론 기화, 응축현상중에 발생되는 불순물까지 여과하기 위해 폐액저장탱크(10), 필터부(20), 예열부(30), 증발기(40), 냉각부(50), 감압필터부(60), 증류액탱크(70) 등을 주요 구성으로 이루어진다.The present invention relates to a vacuum evaporator, wherein the vacuum evaporator condenses the contaminated waste liquid generated in the manufacturing process of washing, dyeing, semiconductor, food processing, etc. at a lower boiling point to extract as a distillate, as well as vaporization, condensation In order to filter the impurities generated during development, the waste liquid storage tank 10, the filter unit 20, the preheating unit 30, the evaporator 40, the cooling unit 50, the reduced pressure filter unit 60, and the distillate tank ( 70) the main configuration.

본 발명에 따른 폐액저장탱크(10)는 폐액을 후술하는 필터부(20)상으로 연속적으로 공급하기 위해 일정량 저장준비하는 탱크로써, 상단에 폐액이 충진되는 투입배관이 펌프와 함께 설치되고, 하단에 폐액을 필터부상으로 공급하는 배출구가 구비된다.Waste liquid storage tank 10 according to the present invention is a tank for preparing a predetermined amount to continuously supply the waste liquid to the filter unit 20 to be described later, the input pipe is filled with the waste liquid at the top is installed with the pump, the bottom The discharge port for supplying the waste liquid to the filter portion is provided.

그리고, 펌프는 폐액저장탱크(10)내에 설치되는 수위감지센서와 연계작동되어 폐액저장량이 저수위로 검출되면 펌프가 작동되어 폐액을 충전하고, 이와 반대로 고수위로 감지되면 펌프의 작동이 OFF되어 폐액저장량을 일정하게 유지시킨다.In addition, the pump is operated in conjunction with the water level sensor installed in the waste storage tank 10, and when the waste liquid storage amount is detected at a low water level, the pump is operated to fill the waste liquid. Keep it constant.

또한, 본 발명에 따른 필터부(20)는 폐액저장탱크(10)와 연결되어 폐액에 포함된 이물질을 여과하도록 제1필터(22)가 구비된다. 필터부(20)는 폐액상에 포함된 이물질(예컨대, 폐액의 종류에 따라 금속입자, 음식물 찌꺼기 등과 같은 고형물)을 1차적으로 여과하는 역할을 수행하고, 여기서 제1필터는 체적당 여과면적이 넓은 드럼필터를 사용하는 것이 바람직하다.In addition, the filter unit 20 according to the present invention is connected to the waste liquid storage tank 10 is provided with a first filter 22 to filter foreign matter contained in the waste liquid. The filter unit 20 serves to primarily filter foreign matter (for example, solid matter such as metal particles, food waste, etc.) included in the waste liquid, and the first filter has a filtration area per volume. It is preferable to use a wide drum filter.

즉, 폐액저장탱크(10)에 저장된 폐액이 필터부(20)상으로 연속주입되면 폐액이 제1필터를 통과하면서 바깥쪽에 고형물을 잔류시키고 여과된 폐액은 중심부로 이송되어 하단에 배출관을 통하여 후술하는 예열부(30)상으로 이송된다.That is, when the waste liquid stored in the waste liquid storage tank 10 is continuously injected onto the filter unit 20, the waste liquid passes through the first filter and the solids remain outside, and the filtered waste liquid is transferred to the center to be described later through a discharge pipe at the bottom. Is transferred onto the preheating unit 30.

또한, 본 발명에 따른 예열부(30)는 필터부(20)를 통하여 여과된 폐액이 이송되는 외관(32)과, 여과된 폐액을 가열하기 위한 고온매체가 이송되는 내관(34)이 구비된다. 여기서 고온매체는 후술하는 증발기(40)에서 발생되는 폐액증기를 사용하도록 내관(34)이 증기이송관(46)과 연결되어 고온의 폐액증기가 내관(34)을 통과하도록 연결된다. 이에 내관(34)을 통하여 폐액증기가 이송되면서 외관(32)을 통과하는 여과된 폐액을 가열하는 구조를 가진다.In addition, the preheating unit 30 according to the present invention is provided with an outer tube 32 through which the waste liquid filtered through the filter unit 20 is transferred, and an inner tube 34 through which a hot medium for heating the filtered waste liquid is transferred. . Here, the high temperature medium is connected to the inner pipe 34 so as to use the waste liquid vapor generated in the evaporator 40 which will be described later so that the hot waste liquid vapor passes through the inner pipe 34. This has a structure that heats the filtered waste liquid passing through the exterior 32 while the waste liquid vapor is transferred through the inner tube 34.

이처럼, 예열부(30)는 후술하는 냉각부에 의해 강제냉각처리되는 폐액증기를 1차적으로 예비냉각하므로 냉각부(50)를 통한 냉각효율이 향상되고, 또 여과된 폐액이 폐액증기의 폐열에 의해 예열되므로 후술하는 증발기(40)를 통한 가열효율이 향상되는 이점이 있다. As such, the preheating unit 30 preliminarily precools the waste liquid vapor forcedly cooled by the cooling unit to be described later, thereby improving the cooling efficiency through the cooling unit 50, and filtering the waste liquid to waste heat of the waste steam. Since it is preheated, there is an advantage that the heating efficiency through the evaporator 40 to be described later is improved.

또한, 본 발명에 따른 증발기(40)는 예열된 폐액이 수용되는 가열탱크(42)와, 가열탱크(42) 내부에 설치되어 열매유가 순환되는 가열코일(44)과, 가열코일(44)에 의해 기화된 폐액증기가 예열부(30)의 내관(34)을 거치도록 증기이송관(46)이 구비된다. 이에 가열탱크(42)내부로 예열된 폐액이 투입되면 가열코일(44)에 의해 비등점이상으로 가열되고, 이때 증발되는 폐액증기는 상단에 형성된 증기이송관(46)을 통하여 상기 예열부(30)를 거쳐 후술하는 냉각부(50)로 이송된 다. 예컨대, 폐액이 세정수일 경우 물은 증발되고 물보다 비등점이 높은 오일, 세정약품 등과 같은 이물질은 가열탱크 하부로 침강되어 드레인 밸브를 통하여 수거된다.In addition, the evaporator 40 according to the present invention includes a heating tank 42 in which the preheated waste liquid is accommodated, a heating coil 44 installed inside the heating tank 42, and a fruit oil circulated, and a heating coil 44. The vapor transfer pipe 46 is provided to pass through the inner pipe 34 of the preheating unit 30 by the vaporized waste liquid vapor. When the waste liquid preheated into the heating tank 42 is injected into the boiling point by the heating coil 44, the waste liquid vapor which is evaporated is transferred to the preheating unit 30 through the steam transfer pipe 46 formed at the upper end thereof. After passing through to the cooling unit 50 to be described later. For example, when the waste liquid is washing water, water is evaporated, and foreign substances such as oils and cleaning chemicals having a higher boiling point than the water are settled under the heating tank and collected through the drain valve.

여기서 열매유는 별도로 구비되는 히터(H)에 의해 연속적으로 가열되어 가열코일(44)을 타고 순환되면서 가열탱크(42)에 저장된 폐액을 간접가열함에 따라 휘발성이 강한 폐액도 위험부담 없이 비등점까지 가열가능한 구조를 가진다.Here, the fruit oil is continuously heated by a heater (H) provided separately and circulated through the heating coil 44, thereby indirectly heating the waste liquid stored in the heating tank 42, so that the volatile waste liquid is heated to the boiling point without any risk. It has a possible structure.

또, 가열탱크(42) 내부 상황 및 폐액저장량을 육안으로 확인가능하도록 측면에 강화유리로 형성된 투명검사창이 형성된다.In addition, a transparent inspection window formed of tempered glass is formed on the side to visually check the internal situation of the heating tank 42 and the amount of waste liquid storage.

그리고, 가열탱크(42)에서 기화된 폐액증기는 후술하는 감압필터부(60)의 에젝터(66)에 의해 고압으로 강제이송되므로 가열탱크(42)내부 기압이 대기압보다 낮게 유지되면서 폐액의 비등점도 낮아진다. 예컨대, 물이 주성분인 폐액의 경우 1기압에서 비등점이 100℃인데 반해, 0.1기압에서는 비등점이 46℃정도이므로 폐액을 비등점까지 가열시 소요되는 에너지가 크게 절감된다.In addition, since the waste vapor vaporized in the heating tank 42 is forcibly transferred to the high pressure by the injector 66 of the pressure reduction filter unit 60, which will be described later, the boiling point of the waste liquid is maintained while the atmospheric pressure inside the heating tank 42 is lower than atmospheric pressure. Also lowers. For example, in the case of the waste liquid mainly composed of water, the boiling point is 100 ° C. at 1 atm, whereas the boiling point is about 46 ° C. at 0.1 atm, which greatly reduces the energy required to heat the waste liquid to the boiling point.

또한, 본 발명에 따른 냉각부(50)는 내관(34)을 통과한 폐액증기가 수용되는 냉각탱크(52)와, 냉각탱크(52) 내부에 설치되어 냉각수가 순환되는 냉각코일(54)과, 냉각코일(54)에 의해 응축된 폐액응축수가 배출되는 응축수이송관(56)이 구비된다. 이에 냉각탱크(52) 내부로 폐액증기가 투입되면 냉각코일(54)에 의해 열교환되어 폐액응축수 상태로 응축되고, 폐액응축수는 응축수이송관(56)을 타고 후술하는 감압필터부의 에젝터상으로 이송된다.In addition, the cooling unit 50 according to the present invention is a cooling tank 52 for receiving the waste liquid vapor passing through the inner tube 34, the cooling coil 54 is installed in the cooling tank 52 and the cooling water circulated and In addition, the condensed water transfer pipe 56 through which the waste liquid condensed water condensed by the cooling coil 54 is provided. When the waste liquid steam is introduced into the cooling tank 52, the waste liquid is heat-exchanged by the cooling coil 54 to condense into the waste liquid condensed water, and the waste liquid condensed water is transported onto the ejector of the decompression filter unit, which will be described later, through the condensed water transfer pipe 56. .

이때, 냉각부(50)상에서 응축된 폐액응축수는 후술하는 에젝터(66)의 흡입력 에 의해 응축수이송관(56)을 통하여 고압으로 배출되므로 냉각탱크(52) 내부 기압이 대기압보다 낮게 유지되어 냉각효율이 향상되고, 또 증발기(40)에서 발생되는 폐액증기를 고압으로 흡입하므로 가열탱크(42) 내부기압이 저하된다. At this time, the waste liquid condensed water condensed on the cooling unit 50 is discharged at a high pressure through the condensate transfer pipe 56 by the suction force of the ejector 66, which will be described later, so that the internal pressure of the cooling tank 52 is kept lower than atmospheric pressure, thereby providing cooling efficiency. This improves, and since the waste liquid vapor generated by the evaporator 40 is sucked at a high pressure, the internal pressure of the heating tank 42 is lowered.

또한, 본 발명에 따른 상기 감압필터부(60)는 폐액응축수를 여과하는 제2필터(62a)가 설치되는 필터실(62)과, 여과된 폐액응축수를 수용하는 폐액응축수탱크(64)와, 폐액응축수탱크(64)에 수용된 폐액응축수를 펌프(P)의 작동에 의해 필터실(62)로 고압분사하면서 응축수이송관(56)과 연결되어 폐액응축수탱크(64)내에 저장된 폐액응축수를 고압으로 흡입하는 에젝터(66)가 구비된다. 여기서 에젝터(Ejector)는 구동유체의 힘으로 흡입력을 발생시키는 통상의 진공발생장치이다.In addition, the pressure reduction filter unit 60 according to the present invention includes a filter chamber 62 in which a second filter 62a for filtering waste liquid condensed water is installed, a waste liquid condensed water tank 64 for receiving the filtered waste liquid condensed water, The waste liquid condensed water contained in the waste liquid condensed water tank 64 is connected to the condensed water conveying pipe 56 while injecting the waste liquid condensed water stored in the waste liquid condensed water tank 64 at a high pressure while spraying the high-pressure waste liquid condensed water contained in the waste liquid condensed water tank 64 into the filter chamber 62. An ejector 66 is provided. Here, the ejector is an ordinary vacuum generator that generates suction by the force of the driving fluid.

그리고, 감압필터부(60)의 폐액응축수탱크(64)는 필터실(62) 중앙으로 돌출되는 연결관(64a) 일단에 이송공(64b)을 관통하여 제2필터(62a)에 의해 여과된 폐액응축수를 흡입하도록 구비된다.In addition, the waste liquid condensed water tank 64 of the pressure reduction filter unit 60 passes through the transfer hole 64b through one end of the connection pipe 64a protruding toward the center of the filter chamber 62 and is filtered by the second filter 62a. It is provided to suck waste liquid condensate.

즉, 펌프(P)의 작동에 의해 폐액응축수탱크(64)에 저장된 폐액응축수를 에젝터(66)를 통하여 필터실(62)로 고압분사되되, 이때 에젝터(66) 일단에 응축수이송관(56)이 연결되어 냉각부(50)를 통과한 폐액응축수를 고압으로 흡입하므로 냉각탱크(52) 및 가열탱크(42)의 내부기압이 대기압보다 낮게 유지된다.That is, by operating the pump P, the waste liquid condensed water stored in the waste liquid condensed water tank 64 is injected into the filter chamber 62 through the injector 66, and at this time, the condensed water transport pipe 56 is connected to one end of the ejector 66. ) Is connected to the waste liquid condensed water passing through the cooling unit 50 at a high pressure so that the internal air pressure of the cooling tank 52 and the heating tank 42 is kept lower than atmospheric pressure.

그리고, 에젝터(66)에 의해 필터실(62)로 투입된 폐액응축수는 스프레이 식으로 분사되어 작은 입자상태로 제2필터(62a)를 통과함에 따라 여과효율이 향상되면서 증발기(40)에서 폐액증기와 함께 증발된 이물질(예컨대, 폐액이 세정수일 경우 오일, 세정약품 등과 같은 이물질)이 2차적으로 여과되고, 여과된 폐액응축수는 연결관(64a)과 이송공(64b)을 통하여 하부에 폐액응축수탱크(64)로 수거된다. 그리고 상기한 작용이 반복되면서 폐액응축수탱크(64)상에 저장된 폐액응축수가 일정수위 이상 증가되면 폐액응축수탱크(64) 일단에 배관을 통하여 연결된 증류액탱크(70)상으로 이송저장되어 재활용된다.The waste liquid condensed water injected into the filter chamber 62 by the injector 66 is sprayed and sprayed to pass the second filter 62a in a small particle form, thereby improving the filtration efficiency and causing the waste liquid vapor in the evaporator 40. With the foreign substances (e.g., foreign substances such as oil, cleaning chemicals, etc., if the waste liquid is washing water) are filtered secondly, the filtered waste liquid condensate is waste liquid condensate at the bottom through the connecting pipe (64a) and the transfer hole (64b) Collected into tank 64. And when the above-described operation is repeated and the waste liquid condensation water stored on the waste liquid condensed water tank 64 is increased by a predetermined level or more, the waste liquid condensed water tank 64 is transferred to and stored on the distillate tank 70 connected through a pipe to one end.

또, 상기 감압필터부(60)의 필터실(62)과 폐액응축수탱크(64)는 냉각드럼(68)에 수용된 상태로 설치되고, 냉각드럼(68)은 냉각부(50)의 냉각코일(54)을 통과한 냉각수가 순환되도록 연결된다. 따라서 냉각부(50)를 통과한 폐액응축수가 2차필터(62a)에 여과되는 중에 냉각드럼(68)으로 순환되는 냉각수에 의해 2차 냉각되므로 폐액응축수에 잔류하는 열로 인한 증발손실이나 압력상승에 따른 폭발이 방지된다.In addition, the filter chamber 62 and the waste liquid condensate tank 64 of the pressure reduction filter unit 60 are installed in the cooling drum 68, and the cooling drum 68 is a cooling coil of the cooling unit 50 ( The cooling water passing through 54 is circulated. Therefore, the waste liquid condensed water that has passed through the cooling unit 50 is secondarily cooled by the cooling water circulated to the cooling drum 68 while being filtered by the secondary filter 62a. Explosions are prevented.
