Description

전기탈수기의 누설전류 차단장치{APPARATUS FOR BLOCKING LEAKAGE CURRENT OF ELECTRIC DEHYDRATOR}Leakage current breaker of electric dehydrator {APPARATUS FOR BLOCKING LEAKAGE CURRENT OF ELECTRIC DEHYDRATOR}

본 발명은 전기탈수기의 누설전류 차단장치에 관한 것으로, 더 상세하게는 전기탈수기에서 전극의 절연 파괴로 인해 누설전류가 본체로 흐르는 것을 방지하고자 한 전기탈수기의 누설전류 차단장치에 관한 것이다.The present invention relates to a leakage current blocking device of an electric dehydrator, and more particularly, to a leakage current blocking device of an electric dehydrator intended to prevent leakage current from flowing to the main body due to dielectric breakdown of an electrode in the electric dehydrator.

전기탈수기는 산업설비에서 발생되는 슬러지에 함유된 수분을 전기영동으로 제거하기 위한 장치로, 이러한 전기탈수기는 일정한 전압을 인가하여 전기장을 형성함으로써 전기장 속에서 대전된 수분을 전기영동과 모세관 현상에 의해 슬러지 입자가 띠고 있는 전하와 반대 전극 측으로 이동시켜 분리한다.An electric dehydrator is a device for removing the water contained in the sludge generated in industrial facilities by electrophoresis. Such an electric dehydrator forms an electric field by applying a constant voltage to the electrophoresis and capillary phenomenon to remove the charged water in the electric field. The sludge particles are separated from the charged charge by moving to the opposite electrode side.

슬러지는 일반 폐기물과는 달리 매립 및 소각처리가 어려운데, 이것은 슬러지에 함유된 유해물질 때문이기도 하지만 보다 중요한 것은 수분 때문으로 슬러지의 수분이 많을 경우 유해성분인 강알카리성 침출수 발생량이 많으며, 또한 소각비용도 추가로 소요된다.Unlike general wastes, sludge is difficult to landfill and incinerate, which is due to the harmful substances contained in the sludge, but more importantly, due to moisture, the amount of strong alkaline leachate, which is a harmful component when sludge is too high, also incineration costs It takes additionally.

따라서, 경제적이고 고효율의 슬러지 탈수 기술은 슬러지가 발생되는 모든 사업장에 요구되는 기술일 뿐만 아니라, 우리나라의 공공 및 사설 슬러지 처리 사업장의 슬러지 폐기물 처리비용 절감과 탈수기 및 탈수설비 제작업 및 슬러지를 이용하여 비료, 사료, 건축재료, 토양개량재 등을 제조하는 슬러지 재활용 업체에 필요한 기반기술이다.Therefore, the economical and high efficiency sludge dewatering technology is not only required for all sludge-generating worksites, but also the cost reduction of sludge waste disposal in public and private sludge treatment plants in Korea, and dehydrator and dewatering equipment manufacturing and sludge. It is a basic technology for sludge recycling companies that manufacture fertilizers, feed, building materials, and soil improvement materials.

이하, 실시예를 통하여 본 발명을 더욱 상세히 설명하기로 한다. 이들 실시예는 단지 본 발명을 예시하기 위한 것이며, 본 발명의 권리 보호 범위가 이들 실시예에 의해 제한되는 것은 아니다.Hereinafter, the present invention will be described in more detail with reference to Examples. These examples are only for illustrating the present invention, and the scope of protection of the present invention is not limited by these examples.

이 과정에서 도면에 도시된 선들의 두께나 구성요소의 크기 등은 설명의 명료성과 편의상 과장되게 도시되어 있을 수 있다. 또한, 후술되는 용어들은 본 발명에서의 기능을 고려하여 정의된 용어들로서 이는 사용자, 운용자의 의도 또는 관례에 따라 달라질 수 있다. 그러므로, 이러한 용어들에 대한 정의는 본 명세서 전반에 걸친 내용을 토대로 내려져야 할 것이다.In this process, the thickness of the lines or the size of the components shown in the drawings may be exaggerated for clarity and convenience of description. In addition, terms to be described below are terms defined in consideration of functions in the present invention, which may vary according to the intention or convention of a user or an operator. Therefore, definitions of these terms should be made based on the contents throughout the specification.

도 1은 본 실시예에 의한 전기탈수기의 누설전류 차단장치의 블럭도이고, 도 2는 다른 실시예에 의한 전기탈수기의 누설전류 차단장치의 블럭도이며, 도 3은 또 다른 실시예에 의한 전기탈수기의 누설전류 차단장치의 블럭도이고, 도 4a와 도 4b는 본 실시예에 의한 전류차단부의 구성을 설명하기 위한 도면이다.1 is a block diagram of a leakage current blocking device of the electric dehydrator according to the present embodiment, Figure 2 is a block diagram of a leakage current blocking device of the electric dehydrator according to another embodiment, Figure 3 is an electrical circuit according to another embodiment 4A and 4B are diagrams for explaining the configuration of the current interruption unit according to the present embodiment.

도 1 내지 도 4b를 참고하면, 본 실시예에 의한 전기탈수기의 누설전류 차단장치는 양전극판(1), 음전극판(2), 전류차단부(3), DC전원부(7)를 포함한다.1 to 4B, the leakage current blocking device of the electric dehydrator according to the present embodiment includes a positive electrode plate 1, a negative electrode plate 2, a current interrupting unit 3, and a DC power supply unit 7.

전기탈수기의 양전극판(1)과 음전극판(2)은 DC전원부(7)로부터 일정한 DC전원을 공급받아 전기장을 형성함으로써 전기장 속에서 대전된 수분을 전기영동과 모 세관 현상에 의해 슬러지 입자가 띠고 있는 전하와 반대 전극 측으로 이동시켜 수분을 분리한다.The positive electrode plate (1) and the negative electrode plate (2) of the electric dehydrator receive a constant DC power from the DC power supply unit (7) to form an electric field, so that the sludge particles are charged with moisture charged in the electric field by electrophoresis and capillary action. Moisture is separated by moving the charge to the opposite electrode side.

전류차단부(3)는 절연물질(31)과 절연물질(31)의 중간에 전도성물질(32)로 이루어져 양전극판(1)과 음전극판(2)을 각각 절연하되, 절연물질 파괴시 누설전류가 전기탈수기의 본체(5)나 가압장치(6)에 흐르지 않도록 전도성물질(32)간에 전기(4)적으로 연결시켜 구성한다.The current blocking unit 3 is made of a conductive material 32 in the middle of the insulating material 31 and the insulating material 31 to insulate the positive electrode plate 1 and the negative electrode plate 2, respectively, but the leakage current when the insulating material is destroyed. The electrical material 4 is electrically connected between the conductive material 32 so that the electric dehydrator does not flow to the main body 5 or the pressurizing device 6.

전도성물질(32)은 절연물질(31)의 중간 둘레에 감기도록 구성하거나, 전도성물질(32)을 절연물질(31)의 중간에 체결시켜 구성한다. 즉, 절연물질(31) 중간에 전도성물질(32)이 위치하도록 구성한다.The conductive material 32 is configured to be wound around the middle of the insulating material 31, or is configured by fastening the conductive material 32 to the middle of the insulating material 31. That is, the conductive material 32 is positioned in the middle of the insulating material 31.

이러한 전류차단부(3)는 흐르는 물이나 가압시 위로 올라간 슬러지와 수증기 등에 의해서 절연물질(31)이 파괴되었을 때 본체(5)로의 저항보다 전도성물질(32)간에 전기적으로 연결된 전선(4)의 저항이 항상 더 작게되므로 절연파괴에 의한 누설전류가 본체(5)로 흐르는 것을 방지한다.The current cut-off part 3 is connected to the electric wire 4 electrically connected to the conductive material 32 rather than the resistance to the main body 5 when the insulating material 31 is destroyed by flowing water or sludge that has risen upon pressurization. Since the resistance is always smaller, leakage current due to dielectric breakdown is prevented from flowing to the main body 5.

결국, 누설전류는 절연파괴시 본체를 통하지 않고 저항이 작은 전류차단부(3)의 전도성물질(32)을 통해서 흐르게 되고, 절연을 파괴한 원인 물질은 자체 저항 열에 의해서 수증기로 증발하게 되어 본체로는 전류가 흐르지 않고 절연 파괴 물질은 사라지게 된다.As a result, the leakage current flows through the conductive material 32 of the current interrupting portion 3 having a small resistance and does not pass through the main body at the time of insulation breakdown, and the causative material which breaks down the insulation evaporates into water vapor by the heat of self-resistance. No current flows and the dielectric breakdown material disappears.

한편, 본 실시예에 의한 전기탈수기의 누설전류 차단 장치는 전류차단부(3)의 전도성물질(32)간에 누설전류를 측정하는 측정부(8)를 더 포함하여, 누설전류가 검출될 경우 경보하도록 구성할 수 있다.On the other hand, the leakage current blocking device of the electric dehydrator according to the present embodiment further includes a measuring unit 8 for measuring the leakage current between the conductive material 32 of the current blocking unit 3, the alarm when the leakage current is detected Can be configured to

정리하면, 본 실시예에 의한 전기탈수기의 누설전류 차단장치는 전기탈수기의 양전극판과 음전극판을 각각 절연함에 있어서, 절연물질의 중간에 전도성물질을 포함하고, 전도성물질간에 전기적으로 연결시켜 구성함으로써 절연물질 파괴시 누설전류가 전도성물질을 통해 흐르게 하므로 누설전류가 본체에 흘러 화재가 발생하는 것을 방지한다.In summary, the leakage current blocking device of the electric dehydrator according to the present embodiment includes a conductive material in the middle of the insulating material and electrically connects the conductive materials in insulating the positive electrode plate and the negative electrode plate of the electric dehydrator, respectively. When the insulating material is destroyed, leakage current flows through the conductive material, preventing leakage current from flowing into the body.
