Description
본 고안은 세정기능을 갖는 폐수 증발 농축 장치에 관한 것으로서, 보다 상세하게는 순환수와 함께 청소용 볼(BALL)을 순환시키며 폐수의 순환 및 농축에 의해 열교환기 튜브 내면에 부착된 고형물 및 스케일을 물리적으로 제거하여 열교환기의 효율을 일정하게 유지하도록 하는것에 관한 것이다.The present invention relates to a wastewater evaporation concentrating device having a cleaning function, and more particularly, circulates a ball for cleaning with circulating water and physically solidifies and scales attached to the inner surface of a heat exchanger tube by circulating and condensing the wastewater. The present invention relates to maintaining the efficiency of the heat exchanger by removing it.
기존의 폐수 증발 농축 장치의 원리를 보면 증기를 이용하여 폐수를 강제증발시켜 오염물질과 물을 분리하는 방법으로서「수직의 열교환기를 이용하여 튜브 내측으로 폐수가 순환되고 튜브 외면에는 열원을 공급하여 순환되는 폐수의 온도를 승온하여 감압된 용기에 스프레이 하면 폐수의 온도가 포화 온도까지 내려가며 비등증발하며 이때 발생된 증기를 스팀이젝터를 이용하여 흡입, 압축하여 튜브외면으로 재 공급하는 자가증발법(FLASH EVAPORATOR) 」을 사용하여 왔다.According to the principle of the conventional wastewater evaporation concentrator, wastewater is forced to evaporate using steam to separate pollutants and water.The wastewater is circulated inside the tube using a vertical heat exchanger and a heat source is supplied to the outside of the tube. When the temperature of the wastewater is raised and sprayed in a depressurized container, the temperature of the wastewater drops to the saturation temperature and evaporates, and the steam generated is sucked and compressed using a steam ejector to resupply to the outside of the tube (FLASH). EVAPORATOR) ”has been used.
이때, 폐수 중에 용존되어 있거나 부유되어 있는 오염물질은 폐수가 증발함에 따라 점점 농도가 높아져 용존 물질은 포화농도 까지 접근하게 된다.At this time, the pollutants dissolved or suspended in the waste water are gradually increased as the waste water evaporates, and the dissolved substances approach the saturation concentration.
폐수중의 물은 증발이 계속되면 용존 물질은 계속 과포화되어 서서히 결정화가 이루어져 불용성 오염물질(또는 부유물질)과 더불어 외부로 배출되고 새로운 폐수가 공급되어 동일한 과정을 거쳐 연속적으로 처리된다.As the water in the waste water continues to evaporate, the dissolved material continues to supersaturate and slowly crystallize, which is discharged to the outside with insoluble pollutants (or suspended solids), and the new waste water is supplied and processed continuously.
이때, 순환되는 폐수는 항상 오염물질의 포화 농도에 근접하여 운전되므로 연속적으로 열교환이 이루어지는 튜브의 폐액 접촉면에 결정화된 오염물질이나 불용성 오염물질이 스케일을 형성, 증기와 폐수간의 열전달을 방해하여 장치의 성능을 저하시킨다.At this time, the circulating wastewater is always operated close to the saturation concentration of the pollutant, so crystallized contaminants or insoluble contaminants form a scale on the waste liquid contact surface of the tube where heat is continuously exchanged, thereby preventing heat transfer between the steam and the wastewater. Decreases performance.
이러한 현상은 폐수가 점점 증발, 농축될수록 더욱 심하게 나타나며 폐수 중의 오염 물질이 과포화되면 결정의 석출과 더불어 장치의 운전이 불가능하게 되므로 일정시간 운전 후 세정이 필요하다.This phenomenon is more severe as the waste water is evaporated and concentrated. If the contaminants in the waste water are supersaturated, the crystals cannot be operated together with the precipitation of crystals.
이러한 이유로 기존의 폐수 증발 농축장치는 시스템의 안정된 운전을 위하여 주기적인 세정이 필요하며 세정방법으로는 화학약품에 의한 세정방법이 일반적이나 이와 같은 화학적 세정방법은 세정액에 의한 2차적 오염물질을 야기시킬 뿐 만 아니라 완벽한 세정이 이루어지지 않아 효율이 떨어지는 문제점이 있었다.For this reason, the conventional wastewater evaporation concentrator requires periodic cleaning for stable operation of the system. As a cleaning method, a chemical cleaning method is generally used. As well as the perfect cleaning was not made there was a problem that the efficiency is lowered.
또한, 이러한 현상을 해결하기 위하여 자율 세정식 열교환기가 국내외에 사용되어 왔지만 제작의 어려움, 적용폐수의 한계성 등을 보이며 적절히 사용되지 못하고 있다.In addition, autonomous cleaning heat exchangers have been used at home and abroad in order to solve this phenomenon, but they are not properly used due to difficulties in manufacturing, limitation of applied wastewater, and the like.
따라서, 본 고안은 상기에서와 같은 종래의 문제점을 해결하기 위하여 고안된 것으로 본 고안의 목적은 순환수와 함께 청소용 볼(BALL)을 순환시켜 열교환기 튜브(TUBE) 내면에 부착되는 고형물을 물리적으로 제거하여 어떠한 조건에서 든지 열교환기의 전열성능을 일정하게 유지하는 세정기능을 갖는 폐수 증발 농축 장치를 제공하는 것이다.Therefore, the present invention was devised to solve the conventional problems as described above, and an object of the present invention is to physically remove a solid attached to an inner surface of a heat exchanger tube by circulating a cleaning ball with circulation water. It is to provide a waste water evaporation concentrating device having a cleaning function to keep the heat transfer performance of the heat exchanger constant under any conditions.

이하, 바람직한 실시예로서 도시하여 첨부된 도면에 따라 본 고안의 실시예를 상세히 설명하면 다음과 같다.Hereinafter, an embodiment of the present invention according to the accompanying drawings shown as a preferred embodiment in detail as follows.
(a) 연속적으로 청소용 볼(BALL)을 순환시켜 열교환기를 세정하고자 하는 경우(a) When trying to clean the heat exchanger by continuously circulating the cleaning ball
상기, 방법의 적용으로서는 유기물에 의한 스케일 형성보다 무기물 및 무기물과 유기물이 혼합되어 스케일이 형성되는 경우에 적용하며 도시된 도1에서와 같이 진공 펌프(13)에 의하여 증발실(1) 및 열교환기(2) 등에 약 100-150토르(torr)의 진공이 형성되면 공급밸브(15)가 열리고 웨이스트 워터 폰드(WASTE WATER POND)(W)로부터 폐수가 공급수 배관(16)을 통해 증발실(1)에 유입된다.The method is applied to the case where the scale is formed by mixing the inorganic material and the inorganic material with the organic material rather than the scale formation by the organic material, and the evaporation chamber 1 and the heat exchanger by the vacuum pump 13 as shown in FIG. (2) When a vacuum of about 100-150 torr is formed, the supply valve 15 is opened and the waste water from the waste water pond is discharged through the feed water pipe 16 to the evaporation chamber 1. Flows into).
증발실(1) 하부에 설치된 액면계(28)까지 폐수가 공급되면 공급밸브(15)가 닫혀지고 순환 펌프(10)가 가동된다.When the wastewater is supplied to the liquid level gauge 28 installed below the evaporation chamber 1, the supply valve 15 is closed and the circulation pump 10 is operated.
가동 후에 볼 차단밸브(14)가 열려 볼세퍼레이션 탱크(3)에 저장되어진 청소용 볼(29)이 유도관(20)을 통하여 낙하하게 된다.After operation, the ball shutoff valve 14 is opened so that the cleaning ball 29 stored in the ball separation tank 3 falls through the induction pipe 20.
낙하된 청소용 볼(29)은 순환배관(18)에 설치된 인젝터(9)를 통하여 순환되고 있는 폐수와 함께 열교환기(2)의 열교환기 튜브(30)내측을 타고 이송하며 열교환기튜브(30) 내면에 부착된 고형물 및 스케일을 제거한다.The dropped cleaning ball 29 is transported through the inside of the heat exchanger tube 30 of the heat exchanger 2 together with the waste water circulated through the injector 9 installed in the circulation pipe 18. Remove the solids and scale attached to the inner surface.
이때, 청소용 볼(29)의 순환속도는 순환수의 유속에 의하여 결정되어 지며 순환수와 함께 이송되어진 청소용 볼(29)은 순환수와 함께 볼 세퍼레이션 탱크(3)로 이송된다.At this time, the circulation speed of the cleaning ball 29 is determined by the flow rate of the circulating water, and the cleaning ball 29 conveyed with the circulating water is transferred to the ball separation tank 3 together with the circulating water.
청소용 볼(29)은 볼세퍼레이션 탱크(3) 내부에 설치되어진 분리판(31)에 부딪쳐 중력에 의해 볼세퍼레이션 탱크(3) 하부로 침강 유도관(20)을 따라 낙하하여 인젝터(9)로 유입되어 진다.The cleaning ball 29 hits the separator 31 installed in the ball separation tank 3 and falls down along the settling guide pipe 20 under the ball separation tank 3 by gravity to injector 9. Flows into.
이러한 연속적인 과정을 거쳐 열교환기(2)의 열교환기 튜브(30) 내면에 부착된 고형물 등을 분리, 제거하게 된다Through such a continuous process, the solid matter attached to the inner surface of the heat exchanger tube 30 of the heat exchanger 2 is separated and removed.
한편, 청소용 볼(BALL)과 함께 볼세퍼레이션 탱크(3)에 유입된 폐수는 볼세퍼레이션탱크(3)로부터 볼과 분리되어 살수관(19)을 통하여 증발실(1) 내부로 이송되어져 스프레이 노즐(8)에 의하여 증발실(1) 내부로 살수된다.Meanwhile, the wastewater introduced into the ball separation tank 3 together with the cleaning ball BALL is separated from the ball from the ball separation tank 3 and transferred to the evaporation chamber 1 through the sprinkling pipe 19 to be sprayed. The nozzle 8 is sprayed into the evaporation chamber 1.
또한, 스팀이젝터(6)을 통하여 스팀이 열교환기(2)의 열교환기 튜브(30)외면에 이송되어 열교환기 튜브(30) 내면으로 순환되는 순환폐수와 열교환이 이루어지며 순환폐수는 증발되기에 적정한 온도로 승온되어져 증발실(1) 내부로 살수되어지며, 이때 증발실(1)은 감압상태이므로 폐수의 온도가 포화 온도까지 내려가며 증발되어지고 농축되어 진다.In addition, the steam is transferred to the outer surface of the heat exchanger tube 30 of the heat exchanger 2 through the steam ejector 6 to exchange heat with the circulating waste water circulated to the inner surface of the heat exchanger tube 30 and the circulating waste water is evaporated. The temperature is raised to an appropriate temperature and the water is sprinkled into the evaporation chamber 1. At this time, since the evaporation chamber 1 is depressurized, the temperature of the wastewater is evaporated and concentrated down to the saturation temperature.
농축된 농축액은 증발실(1) 하측에 설치한 세퍼레이터(4)에 의해 고형물은 분리되어져 농축수 이송펌프(11)에 의해 배출되어져 후처리 공정에 의하여 처리된다.The concentrated liquid is separated by the separator 4 installed under the evaporation chamber 1, and is discharged by the concentrated water transfer pump 11 to be processed by a post-treatment process.
증발실(1)내에 발생된 증기는 증발실 상부에 설치된 데미스터(7)를 통하여 여과되고 여과되어진 증기는 스팀 이젝터(6)에 의해 증기 이송관(21)을 따라 강제흡입되어 열교환기(2)의 열교환기 튜브(30)의 외측으로 공급되어 순환 폐수를 승온하는데 사용되어 진다.The steam generated in the evaporation chamber 1 is filtered through the demister 7 installed at the upper part of the evaporation chamber, and the filtered steam is forcedly sucked along the steam transfer pipe 21 by the steam ejector 6 to exchange heat. Is supplied to the outside of the heat exchanger tube (30) to be used to heat up the circulating wastewater.
스팀이젝터(6)에 의해 재 이용되지 못한 증기는 또다른 증기이송관(24)을 따라 버큠컨덴서(5)로 흡입되어 증기는 응축된 후 드레인 포트(26)에 유입되어 응축수 이송 펌프(12)에 의해 배출되고 불응축성 가스는 진공펌프(13)에 의해 외부로 배출된다.The steam not reused by the steam ejector 6 is sucked into the vacuum condenser 5 along another steam transfer pipe 24 so that steam is condensed and then flows into the drain port 26 to the condensate transfer pump 12. And the non-condensable gas is discharged to the outside by the vacuum pump 13.
이와 같은 과정이 연속적으로 이루어지면서 폐수중의 수분은 증발 응축되어 배출되고 농축된 고형물은 분리 배출된다.As this process is performed continuously, the water in the waste water is evaporated and condensed, and the concentrated solid is separated and discharged.
(b) 주기적으로 청소용 볼을 순환시켜 열교환기를 세정하고자 하는 경우(b) To clean the heat exchanger by circulating the cleaning ball periodically
본 경우는 무기물에 의한 스케일 형성보다 유기물에 의한 스케일 형성이 이루어지는 경우에 적용하며 상세히 설명하면 다음과 같다.In this case, the present invention is applied to the case where the scale is formed by the organic material rather than the scale by the inorganic material.
도시된 도1에서와 같이 구성된 시스템에서 상기 (a)항과 같이 운전되는 것은 같으나 정상적인 운전시에는 청소용 볼(29)을 외부로 빼내어 보관하고 일정한 주기가 되어 열교환기(2)를 세정하고자 할 때에는 청소용 볼(29)을 볼세퍼레이션 탱크(3)에 주입하고 청수를 증발실(1)에 일정량 주입한 후에 순환펌프(10)를 가동하고 볼차단밸브(14)를 연다.In the system configured as shown in FIG. 1, the same operation as the above (a) is performed, but during normal operation, the cleaning ball 29 is taken out and stored outside, and when the heat exchanger 2 is to be cleaned at regular intervals. After the cleaning ball 29 is injected into the ball separation tank 3 and fresh water is injected into the evaporation chamber 1, the circulation pump 10 is operated to open the ball shutoff valve 14.
일정시간이 지나면 볼차단 밸브(14)를 닫은 후에 순환 펌프(10)을 정지하고 볼세퍼레이션 탱크(3)에 청소용 볼(29)을 빼내면 세정이 완료된다.After a certain period of time, after the ball shutoff valve 14 is closed, the circulation pump 10 is stopped and the cleaning ball 29 is removed from the ball separation tank 3 to complete the cleaning.
그리고, 도2는 청소용 볼(29)의 순환 원리도로서 볼세퍼레이션 탱크(3)의 청소용 볼(29)이 순환배관(18)의 일정압에 의하여 볼세퍼레이션 탱크(3)의 하부에서 유도관(20)을 타고 내려오고 순환펌프(10)가 작동하면 도5에서와 같이 인젝터(9)에서 이젝터의 원리에 의하여 청소용 볼(29)이 인젝터(9)로 흡입되어 순환되는 물과 함께 순환배관(18)을 따라 이동한다.2 is a circulating principle diagram of the cleaning ball 29. The cleaning ball 29 of the ball separation tank 3 is guided from the lower portion of the ball separation tank 3 by a constant pressure of the circulation pipe 18. When the circulating pump 10 is driven down through the pipe 20 and the circulating pump 10 is operated as shown in FIG. Move along pipe 18.
순환배관(18)을 따라 이동된 청소용 볼(29)은 열교환기(2)에 인입되고 열교환기(2)에서 일정하게 배열된 청소용 튜브(30)의 내측으로 이송되면서 도3과 같이 열교환기 튜브(30)내측에 난류(亂流:turbulent)를 형성하면서 순환되는 청소용 볼(29)이 열교환기 튜브(30)내측에 부착된 고형물을 제거한다.The cleaning ball 29 moved along the circulation pipe 18 is introduced into the heat exchanger 2 and transferred to the inside of the cleaning tube 30 uniformly arranged in the heat exchanger 2, as shown in FIG. 3. (30) The cleaning ball 29 circulated while forming turbulent turbulent inside to remove the solid matter attached to the inner side of the heat exchanger tube 30.
순환수 및 열교환기(2)에서 제거된 고형물과 함께 볼세퍼레이션 탱크(3)에 유입된 청소용 볼(29)은 도시된 도4와 같이 볼세퍼레이션 탱크(3) 내부에 분리판(3)을 장착하여 청소용 볼(29)과 고형물을 함유한 폐수가 비중에 의하여 분리되도록 하며 분리된 청소용 볼(29)은 유도관(20)을 따라서 하부로 내려오게 된다.The cleaning ball 29 introduced into the ball separation tank 3 together with the solids removed from the circulating water and the heat exchanger 2 is separated from the ball separation tank 3 as shown in FIG. 4. Equipped with a cleaning ball 29 and the waste water containing solids to be separated by the specific gravity and the separated cleaning ball 29 is lowered down along the induction pipe 20.
또한, 볼세퍼레이션 탱크(3)에서 분리된 고형물이 함유된 폐수는 증발실(1) 하부에 설치된 세퍼레이터(4) 중간까지 유도되도록 구성되어 있고 세퍼레이터(4)는 싸이클론 구조로 이루어져 세퍼레이터(4) 하부에 구성된 순환펌프(10)의 흡입력으로 형성된 강한 와류에 의해 원심력을 얻어 유입된 고형물이 순환 펌프(10)에 흡입되지 않고 하부의 침강실(4')로 원할히 침강되어 농축수 이송펌프(11)에 의해 후처리 공정으로 이송할수 있도록 되어 있다.In addition, the wastewater containing the solids separated from the ball separation tank 3 is configured to be guided to the middle of the separator 4 installed under the evaporation chamber 1, and the separator 4 has a cyclone structure. The solid material obtained by centrifugal force by the strong vortex formed by the suction force of the circulation pump 10 configured in the lower portion is smoothly settled into the lower settling chamber 4 'without being sucked into the circulation pump 10, and the concentrated water transfer pump ( 11) can be transferred to the post-treatment process.
이상과 같은 본 고안은 폐수와 함께 청소용 볼을 순환시켜 열교환기 튜브 내면(스케일이 형성되는 부분)에 고형물의 부착을 방지하고 이미 부착된 고형물을 제거 함으로써 열교환기의 전열성능을 유지시켜 줄 수 있다. 또한 분리된 고형물을 효과적으로 제거함으로써 이미 제거된 고형물이 열교환기 튜브에 다시 부착되는 것을 방지할 수 있으며 유기물 또는 무기물에 의해 형성되는 고형물의 특성에 관계 없이 제어할 수 있는 효과가 있다.The present invention as described above can maintain the heat transfer performance of the heat exchanger by circulating the cleaning ball with the waste water to prevent the attachment of solids to the inner surface of the heat exchanger tube (where the scale is formed) and to remove the solids already attached. . In addition, by effectively removing the separated solids, it is possible to prevent the solids that have already been removed from being reattached to the heat exchanger tube, and have an effect that can be controlled regardless of the characteristics of the solids formed by the organic or inorganic material.
