상기 분리탱크 외면(E) 상부 중앙을 통해 내부로 상하이동이 가능하게 설치되는 것으로 고전압 저전류를 인가하여 바이오 반응혼합물에서 글리세린 또는 물을 분리하여 바이오층과 침전물층으로 층분리를 이루고, 층분리된 경계면 높이를 파악하는 층분리 수단(S);으로 이루어진다.The separation tank is installed to be movable vertically through the upper center of the outer surface (E) of the separation tank, and by applying high voltage and low current, glycerin or water is separated from the bioreaction mixture to separate the layers into a bio layer and a sediment layer, and the layers are separated Layer separation means (S) for grasping the height of the interface; consists of.
상기 분리탱크(D)는 원통형으로 상부는 바이오 반응혼합물이 주입되는 유입구(F)를 제외한 부분은 폐쇄되어 있고, 하부는 하방으로 좁아지는 구배로 이루어진 호퍼로 이루어지고, 바이오 배출구(R1)는 호퍼에서 소정 상방에 위치된다. 따라서, 바이오층(바이오디젤 또는 바이오중유)과 침전물층(글리세린 또는 물)으로 층분리된 이후 바이오층의 하부면이 바이오 배출구(R1)의 하방에 위치된 이후로 배출하여 침전물이 바이오 배출구(R1)로 배출되는 것을 방지한다.The separation tank (D) has a cylindrical shape, and the upper part is closed except for the inlet (F) into which the bioreaction mixture is injected, and the lower part consists of a hopper having a downwardly narrowing gradient, and the bio outlet (R1) is a hopper is located above the Therefore, after the bio-layer (biodiesel or bio-heavy oil) and the sediment layer (glycerin or water) are separated into layers, the lower surface of the bio-layer is located below the bio-outlet (R1), and then the sediment is discharged from the bio-outlet (R1). ) to prevent discharge.
상기 층분리 수단(S)은 분리탱크(D)에 바이오 반응혼합물이 주입되면 상부에서 하방으로 소정 이동되면서 고전압 저전류를 가해 침전물을 결집하여 분리시키고, 바이오 배출구(R1)의 하부면의 위치까지 이동된다. 상기 고전압은 10V 이상을 의미하며, 일반적인 고전압 저전류 상태를 의미하므로 그에대한 설명은 생략한다.When the bioreaction mixture is injected into the separation tank (D), the layer separation means (S) collects and separates the sediment by applying a high voltage and low current while moving a predetermined amount from the top to the bottom, and up to the position of the lower surface of the bio outlet (R1). is moved The high voltage means 10V or more, and since it means a general high voltage and low current state, a description thereof will be omitted.
상기 층분리 수단(S)은 분리탱크 외면(E)의 상부면 중앙을 중심으로 +극과 -극이 대향되게 위치하여 상하로 이동이 가능하다. 분리탱크(D) 내부로 바이오 반응혼합물의 주입이 완료되면 층분리 수단(S)의 하부 끝단은 바이오 반응혼합물의 상부영역에 위치하여 글리세린 또는 물이 생성되면서 비중차이에 의하여 하방으로 침전된다. 한편, 층분리 수단(S)은 글리세린 또는 물을 생성하면서 하방으로 소정 하강되며, 바이오 배출구(R1)의 하부면 끝단 위치까지 층분리 수단(S)의 끝단이 하강되고, 층분리가 완료되면 층분리 위치를 파악하고, 바이오디젤(또는 바이오중유)과 글리세린(또는 물)의 배출 이후 상방으로 이동된다.The layer separation means (S) is positioned so that the + and - poles are opposite to each other around the center of the upper surface of the outer surface (E) of the separation tank, so that it can move up and down. When the injection of the bio-reaction mixture into the separation tank (D) is completed, the lower end of the layer separation means (S) is located in the upper region of the bio-reaction mixture and precipitates downward due to the specific gravity difference while glycerin or water is generated. On the other hand, the layer separation means (S) is lowered by a predetermined downward direction while generating glycerin or water, and the end of the layer separation means (S) is lowered to the end position of the lower surface of the bio outlet (R1), and when the layer separation is completed, the layer The separation location is identified, and after the discharge of biodiesel (or bio-heavy oil) and glycerin (or water), it is moved upward.
상기 수위 감지센서(H)는 분리탱크(D)로 바이오 반응혼합물의 주입시 상부 수위 부표(H1)가 감지될 때까지 주입되고, 바이오층 및 침전물층으로 층분리 후 바이오디젤 또는 바이오중유 배출시 바이오 배출 수위 부표(H2)가 감지될 때까지 바이오디젤 또는 바이오중유를 배출하며, 침전물 배출시 하부 수위 부표(H3)가 감지 될 때까지 글리세린 또는 물을 배출한다.The water level sensor (H) is injected until the upper water level buoy (H1) is detected when the bioreaction mixture is injected into the separation tank (D), and after separating the layers into a bio layer and a sediment layer, biodiesel or bio heavy oil is discharged Biodiesel or bio-heavy oil is discharged until the bio-discharge level buoy (H2) is detected, and when sediment is discharged, glycerin or water is discharged until the lower water level buoy (H3) is detected.
상기 부표들(H1, H2, H3)은 일정구간을 제한되게 이동되도록 설치되어 있으며, 부력에 의해 상승하는 재질 내지 중공형태의 부품으로 상부수위 부표(H1)은 분리탱크로 반응혼합물 주입시 최고 수위를 감지되고, 바이오 배출 수위 부표(H2)는 바이오 에너지가 배출될 때 제한된 하강위치(수위)에 도달하면 감지되며, 감지 이후 바이오 에너지의 배출을 완료시킨다.The buoys (H1, H2, H3) are installed to move limitedly in a certain section, and are made of material or hollow parts that rise by buoyancy. is detected, and the bio-discharge water level buoy (H2) is detected when the limited descending position (water level) is reached when the bio-energy is discharged, and the discharge of the bio-energy is completed after detection.
상기 바이오디젤(또는 바이오중유) 배출 후 글리세린(또는 물)의 배출이 진행되는 과정에서 하부 수위 부표(H3)는 하강하면서 제한된 하강위치(수위)에 도달하면 이때의 수위를 감지하여 침전물의 배출이 완료되도록 설치된다.In the process of discharging glycerin (or water) after discharging the biodiesel (or bio-heavy oil), the lower water level buoy (H3) descends and reaches a limited descent position (water level). installed to complete.

Then, biodiesel or bio-heavy oil is discharged.
상기 층분리 감지센서(S)는 9V의 전압의 전원을 인가하여 전압 변동을 측정시켜 바이오층과 침전물층을 구분하며, 상하로 이동이 가능하여 침전물층의 높이를 측정한다.The layer separation detection sensor (S) applies a voltage of 9V to measure the voltage fluctuation to separate the bio layer and the sediment layer, and to measure the height of the sediment layer because it can move up and down.
상기 층분리 감지센서(S)는 전기전도도에 따른 전압을 인식하는 센서가 채용되며, 상하로 이동이 가능하다. 따라서, 침전물층으로부터 상방으로 소정이동하면서 전압을 인식하여 전압이 0V가 인식되는 바이오층이 측정하므로 바이오층과 침전물층이 분리된 여부를 판단하고, 층분리시 침전물층의 높이를 파악할 수 있다. 이때 바이오 배출구(R1)에 침전물층이 위치되었다면 침전물을 선 배출하여 바이오 배출구(R1)로 침전물의 배출을 방지한다.The layer separation detection sensor (S) employs a sensor that recognizes a voltage according to electrical conductivity, and is movable up and down. Therefore, it is possible to determine whether the bio-layer and the sediment layer are separated because the bio-layer in which the voltage is recognized by recognizing the voltage while moving upward from the sediment layer is measured, and determining the height of the sediment layer during the layer separation. At this time, if the sediment layer is located in the bio outlet (R1), the sediment is discharged in advance to prevent the sediment from being discharged to the bio outlet (R1).
