이하에서는 본 발명의 실시예를 첨부되는 도면을 참조하여 상세하게 설명한다. Hereinafter, with reference to the accompanying drawings an embodiment of the present invention will be described in detail.

도 1은 본 발명의 일 실시예에 따른 수처리장치 및 이를 구비한 선박을 나타낸 도면이다.1 is a view showing a water treatment apparatus according to an embodiment of the present invention and a vessel provided with the same.

본 발명의 일 실시예에 따른 선박은 밸러스트 탱크(60)와 밸러스트 탱크(60)에 유입 또는 배출되는 밸러스트수를 처리하는 수처리장치를 포함한다.Ship according to an embodiment of the present invention includes a water treatment apparatus for treating the ballast tank 60 and the ballast water flowing into or out of the ballast tank (60).

그리고, 본 발명의 일 실시예에 따른 수처리장치는, 살균제주입기(10), 전기식 농도측정기(20), 적정식 농도측정기(30), 중화제주입기(40) 및 제어부(50)를 포함한다. In addition, the water treatment device according to an embodiment of the present invention, the sterilant injector 10, the electric concentration meter 20, the titration concentration meter 30, the neutralizer injector 40 and the control unit 50.

살균제주입기(10)는 수처리에 필요한 살균제를 용수에 주입하는 부분이다. 본 실시예의 수처리장치는 살균제로 염소(대표적으로, 차아염소산나트륨)를 사용한다. 특히, 염소는 해수를 전기분해하여 얻을 수 있으므로, 살균제주입기(10)에는 해수를 전기분해하여 염소를 발생시키는 전해장치가 포함될 수 있다. 여기서, 살균제의 투입량은 후술할 전기식 농도측정기(20)의 측정치를 바탕으로 조절된다.The sterilant injector 10 is a part for injecting the sterilant required for water treatment into the water. The water treatment apparatus of this embodiment uses chlorine (typically sodium hypochlorite) as a bactericide. In particular, since chlorine can be obtained by electrolyzing seawater, the disinfectant injector 10 may include an electrolytic device that generates chlorine by electrolyzing seawater. Here, the dosage of the fungicide is adjusted based on the measured value of the electric concentration meter 20 to be described later.

도 1에 도시된 바와 같이, 본 실시예의 살균제주입기(10)는 필터를 통과한 밸러스트수의 유입경로 상에 설치되어 있다.As shown in Figure 1, the sterilant injector 10 of the present embodiment is installed on the inflow path of the ballast water passed through the filter.

전기식 농도측정기(20)는 용수의 전기적 특성변화를 감지하여 용수에 투입된 살균제의 농도를 측정하는 부분이다. 용수에 살균제가 투입되어 용수 속의 전해물질의 성분 및 농도가 달라지면, 용수의 전기적 특성에 변화가 발생한다. 전기식 농도측정기(20)는 용수의 전기적 특성을 감지하므로, 용수 속의 살균제 농도변화를 측정할 수 있다. The electric concentration measuring device 20 is a part for measuring the concentration of the fungicide injected into the water by detecting a change in electrical properties of the water. If a disinfectant is added to the water to change the composition and concentration of the electrolyte in the water, a change in the electrical properties of the water occurs. Since the electric concentration measuring device 20 detects the electrical properties of the water, the concentration of the disinfectant in the water can be measured.

특히, 전기식 농도측정기(20)는 용수의 전기적 특성을 연속적으로 감지할 수 있으므로, 살균제의 농도변화를 실시간으로 측정할 수 있다. In particular, the electric concentration meter 20 can continuously detect the electrical characteristics of the water, it is possible to measure the concentration change of the fungicide in real time.

그러나, 전기식 농도측정기(20)는 지속적으로 사용될 경우, 여러 요인으로 인하여 초기와 달리 오차가 발생하므로 정기적 보정이 필요하다. 또한, 용수의 기본 성분에 따라, 살균제 투입에 따른 전기적 특성변화가 다르게 나타나므로 용수에 따른 보정도 필요하다.However, when the electric concentration measuring instrument 20 is used continuously, an error occurs unlike the initial stage due to various factors, and thus regular calibration is necessary. In addition, according to the basic components of the water, since the electrical properties change according to the disinfectant is introduced differently, correction according to the water is also required.

본 실시예의 전기식 농도측정기(20)로는, 염소의 농도를 측정하는 ORP(Oxidation/ Reduction Potential)측정기가 사용된다. ORP측정기는 물질의 산화 또는 환원되려는 정도가 전위차로 측정되는 기구이다. 이에 따라, ORP측정기의 출력전압을 통하여 밸러스트수에 투입된 염소의 양을 산출할 수 있다. As the electric concentration meter 20 of this embodiment, an ORP (Oxidation / Reduction Potential) meter for measuring the concentration of chlorine is used. ORP meters are instruments in which the degree of oxidation or reduction of a substance is measured by its potential difference. Accordingly, the amount of chlorine introduced into the ballast water can be calculated through the output voltage of the ORP measuring instrument.

한편, 본 실시예에서는 전기식 농도측정기(20)로 ORP측정기를 제시하였으나 이에 한정되지 않으며, 용수의 전기적 특성변화를 감지하여 살균제의 농도를 산출할 수 있는 다양한 형태의 전기식 농도측정기(예를 들면, 전극식 잔류염소측정기)가 사용될 수 있다.On the other hand, in the present embodiment, but the ORP measuring instrument as an electric concentration measuring device 20 is not limited to this, the electric concentration measuring instrument of various forms that can calculate the concentration of the disinfectant by detecting a change in the electrical characteristics of the water (for example, Electrode residual chlorine meter) can be used.

적정식 농도측정기(30)는 화학적정 방식으로 살균제의 농도를 측정하는 부분이다. 화학적정 방식은 용수 속의 살균제와 반응하는 시약을 통하여 살균제의 농도를 측정하는 방법으로, 농도측정의 정확성이 높다. 또한, 시약은 대상물질에 대하여만 반응하므로 용수에서 다른 물질의 조성이 변화하여도 대상물질의 농도변화를 정확히 측정할 수 있다. Titration concentration meter 30 is a part for measuring the concentration of the fungicide in a chemical manner. Chemistry method is a method of measuring the concentration of the disinfectant through a reagent that reacts with the disinfectant in the water, the concentration measurement accuracy is high. In addition, since the reagent reacts only with the target substance, the concentration change of the target substance can be accurately measured even if the composition of the other substance in the water changes.

따라서, 적정식 농도측정기(30)의 측정치를 이용하여 전기식 농도측정기(20)의 측정치를 수시로 보정함으로써, 수처리장치에서 살균제의 농도를 정밀하게 측정할 수 있다.Therefore, the concentration of the fungicide can be precisely measured in the water treatment device by frequently correcting the measurement value of the electric concentration meter 20 using the measurement value of the titration concentration meter 30.

본 실시예의 적정식 농도측정기(30)로는, 염소의 농도를 측정하는 DPD(N, N-diethyl-p-phenylenediamine)비색법 측정기가 사용된다. DPD비색법 측정기는 염소와 반응하는 DPD시약에 의해 발생된 산화물의 비색을 측정하여 염소의 농도를 산출한다. DPD비색법 측정기는 유리잔류염소와 총잔류염소를 구분하여 측정할 수 있으므로 정확한 염소농도 측정이 가능하다. 또한, 해수, 담수에 영향을 받지 않고 염 소의 농도를 정확히 측정할 수 있다. As the titration type concentration meter 30 of this embodiment, a DPD (N, N-diethyl-p-phenylenediamine) colorimetric method for measuring the concentration of chlorine is used. The DPD colorimetric meter calculates the concentration of chlorine by measuring the color of the oxide generated by the DPD reagent reacting with chlorine. DPD colorimetric measuring instrument can measure free chlorine and total residual chlorine for accurate chlorine concentration measurement. In addition, it is possible to accurately measure the concentration of chlorine without being affected by sea water and fresh water.

특히, DPD비색법 측정기에는 산화물의 비색을 자동으로 측정하는 흡광도 측정기가 포함되어 있어서, 전기식 농도측정기(20)의 보정이 상시적으로 이루어질 수 있다. In particular, the DPD colorimetric meter includes an absorbance meter for automatically measuring the color of the oxide, so that the calibration of the electric concentration meter 20 can be performed at all times.

한편, 본 실시예에서는 적정식 농도측정기(30)로 DPD비색법 측정기를 제시하였으나 이에 한정되지 않으며, 화학적정 방식으로 살균제의 농도를 산출할 수 있는 다양한 형태의 적정식 농도측정기(예를 들면, OT법 측정기)가 사용될 수 있다.Meanwhile, in the present embodiment, the DPD colorimetric method is presented as the titration concentration meter 30. However, the present invention is not limited thereto, and various types of titration concentration meters (for example, OT) can calculate the concentration of the fungicide in a chemical manner. Law measuring instruments) may be used.

중화제주입기(40)는 용수에 주입된 살균제를 중화시키는 중화제를 용수에 공급하는 부분이다. 중화제주입기(40)는 보관된 용수를 사용처로 이송하거나 외부로 배출할 때, 용수의 살균제를 제거하기 위한 중화제를 용수에 투입한다. 중화제의 투입량은 상술한 전기식 농도측정기(20)의 측정치를 바탕으로 조절된다. Neutralizer injector 40 is a portion for supplying the neutralizing agent for neutralizing the disinfectant injected into the water. When the neutralizer injector 40 transfers the stored water to a place of use or discharges it to the outside, a neutralizing agent for removing the fungicide of the water is introduced into the water. The input amount of the neutralizing agent is adjusted based on the measurement value of the above-described electric concentration meter 20.

여기서, 중화제의 투입량의 정확도를 더욱 향상시키기 위하여, 용수의 유동경로 상에서 중화제주입기(40)의 상류측 및 하류측 각각에, 전기식 농도측정기(20) 및 적정식 농도측정기(30)의 감지부(22, 24, 32, 34)가 설치될 수 있다. 이에 따라, 중화제가 투입되기 전의 살균제의 농도뿐만 아니라 중화제가 투입된 후의 살균제의 농도도 측정할 수 있어서, 배출되는 밸러스트수의 살균제 중화처리를 철저히 할 수 있다.Here, in order to further improve the accuracy of the input amount of the neutralizing agent, on the upstream side and downstream side of the neutralizing agent injector 40 on the flow path of the water, the sensing unit of the electric concentration meter 20 and the titration concentration meter 30 ( 22, 24, 32, 34 may be installed. Thereby, not only the concentration of the disinfectant before the neutralizing agent is added but also the concentration of the disinfecting agent after the neutralizing agent is added, the disinfectant neutralization treatment of the discharged ballast water can be thoroughly performed.

도 1에 도시된 바와 같이, 본 실시예의 중화제주입기(40)는 밸러스트수의 유동 경로 상에서 살균제주입기(10)와 밸러스트 탱크(60) 사이에 설치된다.As shown in Figure 1, the neutralizer injector 40 of the present embodiment is installed between the sterilant injector 10 and the ballast tank 60 on the flow path of the ballast water.

제어부(50)는 전기식 농도측정기(20)의 측정치에 상응하여, 살균제주입기(10) 또는 상기 중화제주입기(40)를 제어하는 부분이다. 또한, 제어부(50)는 적정식 농도측정기(30)의 측정치에 따라 전기식 농도측정기(20)의 측정치를 보정하는 역할도 한다. 따라서, 제어부(50)는 수처리과정을 전반적으로 제어하는 역할을 한다.The controller 50 is a part for controlling the sterilant injector 10 or the neutralizer injector 40 in correspondence with the measured value of the electric concentration meter 20. In addition, the controller 50 also serves to correct the measured value of the electric concentration meter 20 according to the measured value of the titration concentration meter 30. Therefore, the controller 50 controls the overall water treatment process.

구체적으로, 제어부(50)에 의한 수처리장치의 제어는 아래와 같다.Specifically, the control of the water treatment apparatus by the controller 50 is as follows.

도 2 내지 도 3은 본 발명의 일 실시예에 따른 수처리장치의 작동을 나타낸 도면이다. 2 to 3 is a view showing the operation of the water treatment apparatus according to an embodiment of the present invention.

도 2에 나타난 바와 같이, 밸러스트수가 유입되면, 밸러스트수의 일부가 살균제주입기(10) 내의 전해장치로 유입되어 염소 등의 살균제가 발생되고, 살균제주입기(10)는 살균제를 주입한다. 그리고, 살균제주입기(10) 하류에 설치된 전기식 농도측정기(20) 및 적정식 농도측정기(30)의 감지부(22, 32)가 살균제의 농도를 측정하여 제어부(50)에 전달한다. 이 때, 도 4에 도시된 바와 같이, 전기식 농도측정기(20)의 측정치는 연속적으로 입력되고, 적정식 농도측정기(30)의 측정치는 일정한 간격으로 입력된다.As shown in FIG. 2, when the ballast water is introduced, a part of the ballast water is introduced into the electrolytic apparatus in the sterilizer injector 10 to generate a sterilizer such as chlorine, and the sterilizer injector 10 injects the sterilizer. In addition, the sensing units 22 and 32 of the electric concentration measuring instrument 20 and the titration concentration measuring instrument 30 installed downstream of the sterilizing agent injector 10 measure the concentration of the disinfecting agent and transmit it to the control unit 50. At this time, as shown in Figure 4, the measurement value of the electric concentration meter 20 is continuously input, the measurement value of the titration concentration meter 30 is input at regular intervals.

여기서, 제어부(50)는 전기식 농도측정기(20)의 측정치를 바탕으로 살균제주입기(10)의 살균제 투입량을 실시간으로 조절한다. 더불어, 도 5에 나타난 바와 같이, 제어부(50)는 전기식 농도측정기(20)의 측정치를 적정식 농도측정기(30)의 측정치와 비교하여, 전기식 농도측정기(20)의 측정치를 정기적으로 보정한다.Here, the controller 50 adjusts the amount of disinfectant of the disinfectant injector 10 in real time based on the measured value of the electric concentration meter 20. In addition, as shown in FIG. 5, the controller 50 compares the measurement of the electric concentration meter 20 with the measurement of the titration concentration meter 30, and periodically corrects the measurement of the electric concentration meter 20.

따라서, 실시간으로 밸러스트수의 살균제 농도변화에 따라 살균제의 투입량을 조절하면서도, 정기적으로 보정을 병행하여 정확한 살균제 투입량 조절이 가능하다.Therefore, while controlling the amount of disinfectant in accordance with the change in the concentration of the disinfectant in the ballast water in real time, it is possible to adjust the correct amount of disinfectant in parallel with regular correction.

한편, 밸러스트수 주입은 밸러스트 탱크에 해수를 가두는 과정이므로 밸러스트수 배출 시에 비하여 상대적으로 정밀한 살균제의 농도관리가 필요하지 않으므로, 도 4에 나타난 바와 같이, 전기식 농도측정기(20)의 감지부(22, 24) 중 하나의 감지부(22)만으로 살균제의 농도를 측정하고 살균제 투입량을 제어할 수 있다.On the other hand, the ballast water injection is a process of confining the seawater in the ballast tank, so it is not necessary to control the concentration of the sterilizer relatively accurate as compared to the discharge of the ballast water, as shown in Figure 4, the sensing unit of the electric concentration meter 20 ( Only one detection unit 22 of 22, 24 can measure the concentration of the fungicide and control the amount of fungicide input.

또한, 도3에 나타난 바와 같이, 밸러스트수가 배출되면, 중화제주입기(40) 상류에 설치된 전기식 농도측정기(20) 및 적정식 농도측정기(30)의 감지부(24, 34)가 살균제의 농도를 측정하여 제어부(50)에 전달한다. 그러면, 제어부(50)는 측정치 보정과 더불어 중화제의 주입을 조절한다. In addition, as shown in FIG. 3, when the ballast water is discharged, the sensing units 24 and 34 of the electric concentration measuring instrument 20 and the titration concentration measuring instrument 30 installed upstream of the neutralizing agent injector 40 measure the concentration of the disinfectant. To the control unit 50. Then, the controller 50 adjusts the injection of the neutralizer in addition to the measurement correction.

그리고, 도 3 및 도 4에 나타난 바와 같이, 중화제주입기(40) 하류에도 설치된 전기식 농도측정기(20) 및 적정식 농도측정기(30)의 감지부(22, 32)가 중화 후의 살균제 농도를 측정하여 제어부(50)에 전달하므로, 제어부(50)는 밸러스트수의 중화여부를 모니터링하면서, 중화제 주입을 다시 조절한다. 해양으로 배출되는 밸러스트수는 환경기준에 맞추어 엄격하게 관리되어야 하므로, 본 실시예에서는 밸러스트수의 배출 시에 중화제주입기(40)의 상류측 및 하류측에서 전기식 농도측정기(20) 및 적정식 농도측정기(30)에 의하여 살균제의 농도가 중복체크되게 한다.3 and 4, the sensing units 22 and 32 of the electric concentration meter 20 and the titration concentration meter 30 installed downstream of the neutralizer injector 40 measure the concentration of the fungicide after neutralization. Since it is transmitted to the control unit 50, the control unit 50 controls the injection of the neutralizing agent again while monitoring whether the ballast water is neutralized. Since the ballast water discharged to the ocean should be strictly managed according to environmental standards, in this embodiment, the electric concentration meter 20 and the appropriate concentration meter at the upstream side and the downstream side of the neutralizer injector 40 at the time of discharge of the ballast water. (30) allows the concentration of the fungicide to be overchecked.

한편, 본 실시예의 수처리장치는 전기식 농도측정기(20) 또는 적정식 농도측정기(30) 중 어느 하나의 정상적인 작동이 불가능한 경우에도, 살균제 농도의 측정 및 이를 통한 용수 처리를 수행할 수 있다.On the other hand, the water treatment device of the present embodiment can perform the water treatment through the measurement of the fungicide concentration even when the normal operation of any one of the electric concentration meter 20 or the titration concentration meter 30 is impossible.

구체적으로, 적정식 농도측정기(30)가 작동되지 않는 비상 시를 대비하여 데이터기록부를 추가로 구비할 수 있다. 데이터기록부는, 수처리장치의 정상작동 시에 적정식 농도측정기(30) 및 전기식 농도측정기(20)의 측정치를 저장한다. 이에 따라, 적정식 농도측정기(30)의 고장 시에, 제어부(50)는 데이터기록부의 기록된 데이터를 바탕으로 전기식 농도측정기(20)를 보정하여, 전기식 농도측정기(20)만으로도 비교적 정확하게 살균제 농도를 측정할 수 있다.In detail, the data concentration unit may be further provided in preparation for an emergency in which the titration concentration meter 30 is not operated. The data recording unit stores the measured values of the titration concentration meter 30 and the electric concentration meter 20 in the normal operation of the water treatment apparatus. Accordingly, when the titration concentration meter 30 fails, the controller 50 corrects the electric concentration meter 20 based on the recorded data of the data recorder, so that the concentration of the fungicide is relatively accurate even with the electric concentration meter 20 alone. Can be measured.

또한, 전기식 농도측정기(20)의 고장 시에는, 정상적으로 작동되지 않는 전기식 농도측정기(20)를 적정식 농도측정기(30)가 대체하여 살균제의 농도를 측정할 수 있다.In addition, when the electric concentration measuring device 20 is broken, the proper concentration measuring device 30 may replace the electric concentration measuring device 20 which is not normally operated to measure the concentration of the disinfectant.
