Description

초음파 탁도제거장치Ultrasonic Turbidity Removal Device
본 발명은 초음파 탁도제거장치에 관한 것으로, 보다 상세하게는 탁도가 높은 샘플수가 유입될 경우에도 안정적으로 샘플수를 측정할 수 있도록 하는 초음파 탁도제거장치에 관한 것이다.The present invention relates to an ultrasonic turbidity removal device, and more particularly, to an ultrasonic turbidity removal device capable of stably measuring the number of samples even when sample water with high turbidity is introduced.
일반적으로 해상에서 운송하는 화물 선박은 유사한 화물의 상호 교환을 위하여 왕복 항해하는 선박을 제외하고는 대부분 편도 운항을 한다. 그리고, 편도 운항을 만재 상태로 항해한 후 귀환 항해 시에는 선박의 균형, 안전성 및 조종 성능 향상 등을 위하여 선박평형수(ballast water)를 선내로 유입하여 밸러스트 상태로 항해를 하게 된다.In general, cargo ships transported by sea operate one-way, except for ships that travel round-trip for the mutual exchange of similar cargo. In addition, in the return voyage after navigating one-way in a full state, ballast water is introduced into the vessel to improve the balance, safety, and steering performance of the vessel, and the voyage is performed in a ballast state.
이때, 선박평형수는 한 항구에서 채워져서 다른 곳으로 이송되어, 거기서 새로운 항구 내에 배출된다. 이와 같이, 먼 위치로부터 실려져 온 선박평형수에 포함된 해양 생물 및 병원균의 방출은 새로운 환경에 유해할 뿐만 아니라, 새로운 항구에서도 사람과 동물 모두에게 위험할 수 있다.At this time, the ballast water is filled in one port and transported to another, where it is discharged into the new port. As such, the release of marine organisms and pathogens contained in the ballast water carried from a distant location is not only harmful to the new environment, but also can be dangerous to both humans and animals in the new port.
비-천연적인 해양 생물을 신규 생태계로 도입시키면, 신규 종에 대해 자연적인 방어체계를 지니고 있지 않을 수 있는 천연 식물군 및 동물군에게 파괴적인 효과를 미칠 수 있다. 또한, 콜레라와 같은 해로운 세균성 병원균이 원래의 항구에 존재할 수 있다. 이러한 병원균은 시간이 지남에 따라 밸러스트 탱크 내에서 증식되어, 이들이 방출되는 영역에서 질병을 발생시킬 수 있다.The introduction of non-natural marine life into a new ecosystem can have devastating effects on native flora and fauna that may not have natural defenses against the new species. In addition, harmful bacterial pathogens such as cholera may be present in the original port. These pathogens can multiply in the ballast tanks over time and cause disease in the area where they are released.
이러한 해양 생물 및 병원균에 의해 제기되는 위험은 선박평형수 내에 존재하는 상기한 종들을 치사(致死)시켜 조절할 수 있다.The risks posed by these marine organisms and pathogens can be controlled by killing the above-mentioned species present in the ballast water.
선박평형수를 살균 처리하는데 주로 전기 분해 방식을 이용하는데, 전기 분해 방식을 이용한 선박평형수 처리 시스템은 선박평형수의 TRO 측정하기 위한 TRO 센서를 구비하고 있다. The electrolysis method is mainly used to sterilize the ballast water, and the ballast water treatment system using the electrolysis method is equipped with a TRO sensor for measuring the TRO of the ballast water.
여기서 "TRO"는 "Total Residual Oxidant"의 약어로서, 선박평형수에 존재하는 전체 잔류 산화제를 의미하며, 통상적으로 전기 분해 과정을 통하여 발생하는 염소가 선박평형수 내의 수중 생물을 산화시키고 남은 염소의 잔류 염소 수치를 측정하여 구한다. TRO는 바닷물이나 염분이 섞여있는 물을 전기분해 또는 염소 소독할 경우 활성 염소 대신 브로민 등의 원자로 대체되어 여러 종류의 산화제가 공존하게 되는데, 이때 존재하는 모든 활성 산화제를 가리킨다.Here, "TRO" is an abbreviation of "Total Residual Oxidant", meaning the total residual oxidizing agent present in the ballast water, and the chlorine generated through the electrolysis process oxidizes the aquatic organisms in the ballast water and the remaining chlorine It is determined by measuring the residual chlorine level. In the case of electrolysis or chlorine disinfection of seawater or salt water, TRO is replaced with atoms such as bromine instead of active chlorine, and various kinds of oxidizing agents coexist. It refers to all active oxidizing agents present.
전술한 TRO센서는 선박이 항해하는 경로에 따라 담수, 해수 등 다양한 수질 조건에서 작동해야 하기 때문에, 수질변화에 덜 민감한 DPD 시약을 이용한 TRO 센서를 주로 사용한다. Since the above-described TRO sensor has to operate in various water quality conditions such as fresh water and sea water depending on the route the vessel navigates, a TRO sensor using a DPD reagent that is less sensitive to changes in water quality is mainly used.
그러나, 탁도가 높은 지역에서는 DPD방식 TRO센서로 유입되는 샘플수의 탁도가 높아 센서의 측정값이 불안정해지는 문제점이 있다. However, there is a problem in that the turbidity of the sample water flowing into the DPD type TRO sensor is high in an area with high turbidity, so that the measured value of the sensor becomes unstable.
또한, 샘플수의 유입 유로상에 필터를 설치하더라도 탁도가 높은 샘플수에 의해 막힘 현상이 발생할 수 있으며, 그 결과 샘플수의 TRO 측정이 불가능해지는 문제점이 있다.

여기서, v는 유로내의 평균유속(m/sec)이고, d는 유로의 내경(m)이고, υ는 액체의 동점도(m2/sec)이다.Here, v is the average flow velocity in the flow path (m/sec), d is the inner diameter of the flow path (m), and v is the dynamic viscosity of the liquid (m 2 /sec).
유로(121)를 유동하는 샘플수가 층류로 유동되기 위해서는 상기식에 의해 산출되는 레이놀드수가 2100보다 작아야 한다. 따라서, 평균유속과 유로(121)의 내경을 층류가 되도록 설계하여야 하는데, 본 발명의 실시예에서는 샘플수가 균일하게 섞이고 초음파 진동자(135)의 초음파 전이 효과가 크도록 유로(121)에서의 유속이 빠르게(대략 2~3m/s) 설계하기 때문에 이에 따라 유로(121)의 단면적을 작게 하여야 한다. In order for the sample water flowing through the flow path 121 to flow in a laminar flow, the Reynolds number calculated by the above equation should be less than 2100. Therefore, the average flow rate and the inner diameter of the flow path 121 should be designed to be a laminar flow. In the embodiment of the present invention, the flow velocity in the flow path 121 is increased so that the number of samples is uniformly mixed and the ultrasonic transfer effect of the ultrasonic vibrator 135 is large. Since it is designed quickly (approximately 2-3 m/s), the cross-sectional area of the flow path 121 should be reduced accordingly.
이를 위해, 일실시예로서 전술된 바와 같이 단면이 제2커버(120)의 내측면 및 외측면 방향으로는 초음파 세척력을 향상시키도록 길이가 더 길게 형성되고 이에 수직인 면들은 짧게 형성된 장방형으로 형성되는 배플 형식(baftle type)의 유로(121)가 적용될 수 있다. To this end, as described above as an embodiment, the cross-section is formed to be longer in length to improve ultrasonic cleaning power in the direction of the inner and outer surfaces of the second cover 120, and the surfaces perpendicular thereto are formed in a short rectangular shape. A flow path 121 of a baffle type may be applied.
여기서, 유로(121)의 배플 팩터(Baffle factor)는, 아래 식에 의해 계산될 수 있다. Here, the baffle factor of the flow path 121 may be calculated by the following equation.
배플 팩터 = T10 / T Baffle factor = T 10 / T
= (배출농도가 유입농도의 10%에 도달하는 시간) / (유로의 용량/유속)= (time for the outlet concentration to reach 10% of the inlet concentration) / (flow volume/flow rate)
본 발명의 일실시예에서 배플 팩터는 0.6 ~ 0.8 범위, 보다 바람직하게는 대략 0.7가 되는 것이 바람직하다. In one embodiment of the present invention, the baffle factor is preferably in the range of 0.6 to 0.8, more preferably about 0.7.
전술된 바와 같이, 본 발명의 일실시예에 따른 초음파 탁도제거장치(100)는 유로(121)에서 층류를 유지하는 것이 중요하다. 난류 유동이 발생할 경우, 샘플수 유동에 교란이 발생하거나 사장체적이 형성될 수 있고, 기포가 발생될 가능성이 커지게 된다. 기포가 발생되면, 기포에 의해 초음파 진동자(135)로부터 초음파 전이가 방해되어 필터(149)에 부착된 이물질의 분리 효율이 저하될 뿐만 아니라　초음파 진동자(135)도 손상(damage)을 받게 된다.As described above, in the ultrasonic turbidity removal apparatus 100 according to an embodiment of the present invention, it is important to maintain a laminar flow in the flow path 121 . When turbulent flow occurs, disturbance of the sample water flow may occur or dead volume may be formed, and the possibility of generating air bubbles increases. When bubbles are generated, ultrasonic transfer from the ultrasonic vibrator 135 is prevented by the bubbles, so that the separation efficiency of foreign substances attached to the filter 149 is lowered, and the ultrasonic vibrator 135 is also damaged.
본 발명에서는 앞서 언급된 바와 같이 방향전환부(121a,121b,121c)가 라운드지게 형성되어 사장체적을 최소화할 뿐만 아니라 유로(121)내에서의 층류 조건을 유지하도록 구성함으로써 이러한 범위의 배플 팩터를 가질 수 있게 된다.In the present invention, as mentioned above, the direction changing parts 121a, 121b, and 121c are formed to be rounded to minimize the dead volume and maintain the laminar flow condition in the flow path 121, thereby increasing the baffle factor in this range. be able to have

Here, a gasket 155 is installed between the ultrasonic vibrator fixing plate 130 and the recess 127 to prevent the sample water flowing through the flow path 121 from leaking to the outside.
본 발명의 일실시예에 따른 제1커버(110) 및 제2커버(120)는 내부식성 및 가공성이 우수하고 초음파 진동자(135)의 진동을 효과적으로 흡수할 수 있는 소재인 PVC로 형성되는 것이 바람직하다. The first cover 110 and the second cover 120 according to an embodiment of the present invention are preferably formed of PVC, which is a material that has excellent corrosion resistance and workability and can effectively absorb the vibration of the ultrasonic vibrator 135 . do.
본 발명의 일실시예에서 필터(140)는, 판형으로 형성되어 제1커버(110)의 내측면에 형성된 안착부(111)에 안착된다. 여기서, 필터(140)는 탁도가 높은 해수에 포함될 수 있는 클레이(clay)의 제거효율이 높아야 하며 필터(140)를 통과하여 샘플수 측정장치(미도시)로 배출될 샘플수의 샘플링이 원활하도록 적정한 유동(flux)이 확보되어야 한다. 이를 만족시키는 필터의 일례로, 소결 금속 필터(Sintered metal filter)가 있다. 본 발명의 실시예에서 소결 금속 필터는 스테인레스 재질로 형성되고, 공극은 클레이를 제거하기 위해 대략 2㎛로 설계하고, 기공률(porosity)은 대략 60%인 것이 바람직하다.In one embodiment of the present invention, the filter 140 is formed in a plate shape and is seated on the seating portion 111 formed on the inner surface of the first cover 110 . Here, the filter 140 should have a high removal efficiency of clay that may be included in seawater with high turbidity, and to smoothly sample the number of samples that pass through the filter 140 and be discharged to a sample number measuring device (not shown). Adequate flux must be ensured. As an example of a filter that satisfies this, there is a sintered metal filter. In an embodiment of the present invention, it is preferable that the sintered metal filter is made of a stainless material, the pores are designed to be about 2 μm to remove the clay, and the porosity is about 60%.
본 발명의 실시예에서 소결 금속 필터를 적용할 경우, 초음파 진동자(135)의 주파수는 대략 40kHz~1MHz, 특히 바람직하게는 40kHz, 출력은 100W 조건에서 세척 효율이 가장 우수하고, 필터(140)를 통과하는 유동(flux)이 일정하게 유지될 수 있게 된다.In the case of applying the sintered metal filter in the embodiment of the present invention, the frequency of the ultrasonic vibrator 135 is approximately 40 kHz to 1 MHz, particularly preferably 40 kHz, and the cleaning efficiency is the best under the conditions of 100 W, and the filter 140 is The passing flux can be kept constant.
도 6은 본 발명의 일실시예에 따른 초음파 탁도제거장치에 구비된 제2커버의 평면도로서 샘플수의 바이패스 유동을 도시한 것이고, 도 7은 샘플수 바이패스시의 본 발명의 일실시예에 따른 초음파 탁도제거장치에서의 유동 및 필터에서 이탈된 클레이를 도시한 것이다. 여기서, 도 7 및 도 8은 유동 및 클레이 분리상태를 잘 표현하기 위해 제1커버, 필터 및 제2커버가 분리된 형태로 표시되었지만, 실제로는 결합된 상태에서 동작하게 된다. 이하에서 도 1 내지 도 5와 동일한 도면부호를 가지는 구성은 동일한 기능을 하는 동일한 구성으로, 그 설명을 생략하고 차별되는 구성을 중심으로 설명한다.6 is a plan view of a second cover provided in the ultrasonic turbidity removal device according to an embodiment of the present invention, showing the bypass flow of sample water, and FIG. 7 is an embodiment of the present invention when the sample water is bypassed. It shows the clay separated from the flow and filter in the ultrasonic turbidity removal device according to the present invention. Here, in FIGS. 7 and 8, the first cover, the filter and the second cover are shown in a separated form in order to well express the flow and the clay separation state, but they are actually operated in a combined state. Hereinafter, components having the same reference numerals as those of FIGS. 1 to 5 are identical components that perform the same functions, and descriptions thereof will be omitted and the differentiated components will be mainly described.
도 6 및 도 7을 참조하면, 제2커버(120)에 구비된 유입부(125)를 통해 샘플수가 유입되고, 이후 방향전환부(121a,121b,121c)를 통해 3번 방향이 전환되며 유동된 다음 배출부(126)를 통해 배출됨으로써 바이패스 유동이 완료된다. 이와 같이 바이패스 유동은 샘플링부(115)로 샘플링되지 않고 바이패스되어 유로(121)로만 유동되게 된다. 6 and 7 , the sample water flows in through the inlet 125 provided in the second cover 120 , and then the direction is changed 3 times through the direction changing parts 121a , 121b and 121c to flow. Then, the bypass flow is completed by being discharged through the discharge unit 126 . As such, the bypass flow is bypassed without being sampled by the sampling unit 115 to flow only through the flow path 121 .
이러한 바이패스 유동시, 도 7에 도시된 바와 같이 초음파 진동자(135)가 ON되어 진동이 샘플수를 통해 필터(140)로 전달된다. 그 결과, 필터(140)에 부착된 클레이(180)가 필터(140)로부터 이탈되어 바이패스 유동하는 샘플수에 의해 초음파 탁도제거장치(100)의 외부로 배출되면서 필터(140)의 막힘을 방지하게 된다. 여기서, 바이패스 유동은 예를 들면 30초 동안 수행될 수 있다.During this bypass flow, as shown in FIG. 7 , the ultrasonic vibrator 135 is turned on and the vibration is transmitted to the filter 140 through the sample water. As a result, the clay 180 attached to the filter 140 is discharged from the filter 140 and discharged to the outside of the ultrasonic turbidity removal device 100 by the bypass-flowing sample water to prevent clogging of the filter 140 . will do Here, the bypass flow may be carried out, for example, for 30 seconds.
도 8은 샘플수 샘플링시의 본 발명의 일실시예에 따른 초음파 탁도제거장치에서의 유동 및 필터 표면에 부착된 클레이(clay)를 도시한 것이다.FIG. 8 shows the flow in the ultrasonic turbidity removal device according to an embodiment of the present invention during sampling of sample water and clay attached to the filter surface.

Referring to FIG. 8 , the sample water flows along the flow path 121 provided in the second cover 120 during sampling, and some of the sample water is sampled through the sampling unit 115 branched from the flow path 121 , , the remainder is discharged through the discharge unit 126 . As described above, during sampling, the ultrasonic vibrator 135 is turned off, and as the sample water passes through the filter 140 and is discharged to the sampling unit 115 , the clay 180 is accumulated on the surface of the filter 140 . Here, the sampling may be performed for a longer period of time than during the bypass flow, for example, 60 seconds. Meanwhile, the accumulated clay 180 is removed while the ultrasonic vibrator 135 is turned on during the bypass flow of FIG. 7 as described above.
도 7 및 도 8의 실시예에서, 제1커버(110)는 상측에 위치하고 제2커버(120)는 하측에 위치하도록 설치되는 것이 바람직하다. 이와 같이 설치됨으로써 필터(140)에서 이탈된 클레이(180)가 중력에 의해 하방으로 낙하하여 하측에 위치한 제2커버(120)의 유로(121)를 통해 배출부(126)를 배출된다.In the embodiment of Figures 7 and 8, the first cover 110 is preferably installed so as to be positioned on the upper side and the second cover 120 is positioned on the lower side. By being installed in this way, the clay 180 separated from the filter 140 falls downward by gravity, and the discharge part 126 is discharged through the flow path 121 of the second cover 120 located at the lower side.
