원심형 수로를 다중 구비한 전기분해 귀금속 회수장치Electrolytic precious metal recovery device with multiple centrifugal channels
본 발명은 귀금속 회수성능을 획기적으로 향상시키고, 소형화되어 점유공간을 줄이고 취급관리 및 운반 편의성이 증대되도록 하는 원심형 수로를 다중 구비한 전기분해 귀금속 회수장치에 관한 것이다.The present invention relates to an electrolytic noble metal recovery apparatus having multiple centrifugal channels to dramatically improve the noble metal recovery performance, miniaturization to reduce the occupied space and to increase the handling and transport convenience.
일반적으로 산업용 금을 사용하는 금도금 또는 인쇄회로기판 제작현장 등에서 도금 세척수나 도금액 등에 포함되어 있는 금을 비롯한 귀금속을 회수하고 있으며, 이러한 귀금속은 고가물이라는 특성을 갖는 만큼 특히 회수율을 극대화시켜 유실을 방지함과 아울러 높은 회수성능이 요구된다.In general, gold plating using industrial gold or printed circuit board manufacturing sites recovers precious metals including gold contained in plating wash water or plating solutions, and these precious metals are expensive. In addition, high recovery performance is required.
도금 세척 폐수 등에 포함된 금 등의 귀금속입자는 도금 과정에서 침전을 방지하기 위하여 도금용액에 투입되는 유기물인 구연산과 결합되어 있으며 귀금속의 회수는 주로 전기분해방식이나 음이온수지 흡착방식이 사용되고 있다.Precious metal particles such as gold contained in the plating washing waste water are combined with citric acid, which is an organic substance added to the plating solution, in order to prevent precipitation in the plating process, and the recovery of the precious metal is mainly performed by electrolysis or anion resin adsorption.
이중에서 전기분해방식은 전기투과력으로 구연산 안에 있는 귀금속입자를 전리시키고 양극에서 음극으로 이동하는 전류의 흐름을 이용하여 음극부재에 귀금속입자가 흡착 석출되도록 하여 회수하는 것이다.The electrolysis method is to ionize the precious metal particles in the citric acid by electrotransmission and recover them by allowing the precious metal particles to be adsorbed and precipitated on the cathode member by using a current flow from the anode to the cathode.
종래기술의 전기분해 귀금속 회수장치는 대한민국 등록실용신안 제20-0448283호(2010.03.23. 등록) 등에 개시되어 있는 바와 같이, 양극 및 음극을 띠는 전극부재 사이로 극소량의 귀금속을 함유하고 있는 귀금속함유 처리수가 통과되도록 구성되는데 양극부재 및 음극부재에 귀금속함유 처리수의 접촉시간이 균등하지 않고, 또한 충분한 석출 면적을 필요로 하나 기기의 규모에 한계가 있으며 회수속도가 느려 도금 수세조의 처리속도를 따라가지 못하는 문제점이 있다.The electrolytic noble metal recovery apparatus of the prior art contains a precious metal containing a very small amount of precious metal between the electrode member having a positive electrode and a negative electrode, as disclosed in Korean Utility Model No. 20-0448283 (registered on March 23, 2010). It is configured to pass the treated water, and the contact time of the treated water containing precious metal to the anode and cathode members is not equal, and it also needs a sufficient precipitation area, but the size of the equipment is limited and the recovery speed is slow, so There is a problem that can not be followed.

The recovery rate is low due to residual precious metal particles, etc., and the economic loss is large.
또한, 잔류 귀금속을 회수하기 위하여 수차에 걸쳐 반복적으로 재순환 회수작업을 수행함으로써 막대한 시간과 가동에너지가 소요되고 더 많은 기기를 필요로 하게 되는 문제가 있다.In addition, there is a problem in that a large amount of time and operating energy is required and more equipment is required by repeatedly carrying out a recirculation recovery operation to recover residual precious metals.
본 발명은 상기한 문제점을 해소하기 위한 것으로서,The present invention is to solve the above problems,
본 발명의 목적은 1회 유입된 귀금속함유 처리수가 0ppm에 이르기까지 전기분해 회수가 이루어져 귀금속의 회수량, 회수율, 회수속도 및 회수성능이 획기적으로 향상되도록 하는 원심형 수로를 다중 구비한 전기분해 귀금속 회수장치를 제공함에 있다.An object of the present invention is to electrolytic recovery of the precious metal-containing treated water flows up to 0 ppm, so that the recovery rate, recovery rate, recovery rate, and recovery performance of the precious metal are dramatically improved. In providing a recovery device.

본 발명은 망체 또는 다공판체로 이루어지는 원통형의 음극부재(21) 및 음극부재들 사이에서 구획벽으로도 기능하는 원통형의 양극부재(31)가 동심원 상으로 다중 형성됨으로써 하나의 케이싱(10) 내에서 전기분해 귀금속 회수 구획공간 및 원심형 우회 수로가 다중 형성되어 귀금속의 전기분해 회수가 연속 반복적으로 복수회 이루어지고 이에 따라 귀금속 회수속도 및 회수율을 획기적으로 향상시킨다.According to the present invention, a cylindrical cathode member 21 made of a mesh or a porous plate body and a cylindrical anode member 31 also serving as a partition wall between the cathode members are formed in a concentric circle, thereby forming a single casing 10. The electrolytic noble metal recovery partition space and the centrifugal bypass channel are formed in multiple times, and the electrolysis recovery of the noble metal is repeatedly performed a plurality of times, thereby dramatically improving the noble metal recovery rate and recovery rate.
귀금속함유 처리수가 음전극부(20)의 중심인 제1음극부재(211) 내부로 유입되어 제1음극부재(211) 및 제1양극부재(311) 구획공간에서 이루어지는 1차 전기분해 회수단계에서 귀금속의 대부분의 양이 회수되고, 귀금속이 극소 잔류하는 귀금속함유 처리수는 제2음극부재(212) 및 제2양극부재(312)가 형성하는 2차 구획공간에서 2차 회수가 이루어지는 식으로 n차에 이르기까지 귀금속의 전기분해 회수가 연속 반복적으로 복수회 이루어진다.The precious metal-containing treated water flows into the first negative electrode member 211, which is the center of the negative electrode part 20, and then becomes a precious metal in the first electrolytic recovery step performed in the compartments of the first negative electrode member 211 and the first positive electrode member 311. Most of the amount of is recovered, and the precious metal-containing treated water in which the precious metal is extremely remaining is n-th ordered in such a manner that secondary recovery is performed in the secondary partition space formed by the second cathode member 212 and the second cathode member 312. The electrolysis recovery of the noble metal is repeatedly performed a plurality of times up to.
예컨대, 도 1 등에 도시된 바와 같이, 음극부재(21) 및 양극부재(31)가 4중으로 형성될 경우 귀금속함유 처리수는 4차에 걸쳐서 전기분해 회수가 각각의 구획공간을 거치면서 연속 반복적으로 이루어지며, 이는 처리수의 1회 유입으로 종래기술의 귀금속 회수장치를 4회 순환한 것과 같은 효과를 얻게 되는 것이다.For example, as shown in FIG. 1 and the like, when the negative electrode member 21 and the positive electrode member 31 are formed in quadruple, the treated water containing noble metal is repeatedly and repeatedly while the electrolysis recovery passes through each partition space over four orders. This is achieved by the same effect as circulating the precious metal recovery device of the prior art four times with one inflow of treated water.
또한, 동심원 상으로 다중 형성된 음극부재(21)들이 정회전 또는 정역회전되는 구조로 되어 원심력에 의하여 와류가 발생되고 귀금속함유 처리수가 음극부재(21)의 전체 면적에 균등하게 접촉함으로써 귀금속입자가 음극부재의 전체면적에 고르게 흡착 석출되어 종래기술에서 서릿발 형태로 편중 석출되어 귀금속입자가 탈락되는 현상이 방지되고, 회수과정이 신속하게 이루어져 회수율 및 회수속도가 현저히 향상된다.In addition, since the negative electrode members 21 formed in multiple concentric circles are rotated forward or reversely, vortices are generated by centrifugal force, and the precious metal-containing treated water contacts the entire area of the negative electrode member 21 so that the precious metal particles are negative. The adsorption precipitate is evenly deposited on the entire area of the member to prevent delamination in the form of frost in the prior art, thereby preventing the dropping of precious metal particles, and the recovery process is rapidly performed, thereby significantly improving the recovery rate and recovery rate.
또한, 다중으로 형성되는 양극부재(31)들에 수로용 관통부(32)가 상부와 하부에 교호로 형성되는 우회 원심형 수로를 형성함으로써 귀금속함유 처리수가 음극부재(21)와 접촉할 수 있는 거리를 길게 연장시켜 좁은 공간으로서도 충분한 회수성능을 구현할 수 있다.In addition, by forming a bypass centrifugal channel in which the water passage through portions 32 are alternately formed in the upper and lower portions of the anode members 31 formed in a plurality, the precious metal-containing treated water may contact the cathode member 21. By extending the distance long enough recovery performance can be realized even in a narrow space.
여기에 더하여, 도 5 및 도 6에 도시된 바와 같이, 수로용 관통부(32)가 인접하는 양극부재(31) 간에 상호 180° 상에 위치될 경우 우회 원심형 수로의 길이를 더욱 연장시킬 수 있어 한정된 공간에서 회수율을 극대화할 수 있다.In addition, as shown in FIGS. 5 and 6, the length of the bypass centrifugal channel can be further extended when the water passage penetrating portions 32 are positioned at 180 ° to each other between adjacent anode members 31. The maximum recovery rate can be maximized in a limited space.

The noble metal-containing treated water introduced once is repeatedly and repeatedly subjected to electrolysis recovery, thereby dramatically improving the recovery rate, recovery speed and recovery performance, and by rotating the negative electrode member, the precious metal particles are uniformly deposited on the entire area of the negative electrode member by centrifugal force. It is recovered to prevent dropping and significantly improve the recovery speed and recovery performance.
