폐납축전지 스크랩(scrap)에서 금속납과 규산납을 기본으로 하는 프릿트유를 제조하는 방법Method for manufacturing frit oil based on metal lead and lead silicate in scrap of lead acid battery scrap
[발명의 상세한 설명]Detailed description of the invention
본 발명은 폐납축전지(Batlery)의 극판스크랩(scrap)을 반사로에서 탄소분말 및 규산분말을 혼합용해 반응하게 하여 폐납축전지스크랩(scrap)에서 금속납과 규산납을 기본으로 하는 프릿트유(釉)를 제조하는 방법에 관한 것이다. 납축전지는 자동차용, 통신용 등 직류전원으로 다양하게 사용되고 있으며 그 수명이 다되면 계속적을 폐기되고 있어 효율적으로 공해를 발생하지 않는 폐자원의 재생이용의 방법이 요구되고 있다. 그런데 종래의 폐축전지 스크랩의 용해제련 방법은 반사로, 견로(堅爐)등을 이용하여 극판격자(格子)의 금속납의 용해와 활물질(活物質)인 산화납, 황산납의 환원제련을 위하여 석회석, 철분, 탄분을 사용하여 작업온도가 높아야 하기때문에 납이 쉽게 휘발하여 매연이 발생되고, 미환원 또는 환원상태의 금속납이 광재와 함께 따라나와 납의 회수율이 떨어지고 심한 공해발생의 요인이 되었다.The present invention is to mix the carbon powder and silicic acid powder in a reflecting furnace by reacting the electrode plate scrap of the battery (Batlery) with a frit oil based on the metal lead and lead silicate in the scrap of the lead-acid battery scrap It relates to a manufacturing method. Lead-acid batteries are widely used as direct current power supplies for automobiles, telecommunications, etc., and when their lifetimes are over, they are continuously being discarded, and a method of recycling waste resources that does not generate pollution efficiently is required. However, the conventional method for dissolving waste scrap of spent batteries is a limestone, for the melting of metal lead in the electrode plate grid and the refining of lead oxide and lead sulfate, which are active materials using a reflector, a gyro, etc. Since the working temperature must be high using iron and coal powder, lead is easily volatilized and soot is generated, and unreduced or reduced metal lead is accompanied with the slag, and the recovery rate of lead is reduced, which causes severe pollution.
이와같은 종래의 방법에 의해 폐축전지 스크랩의 용해제련하는 방법의 실시예는 다음과 같다.An embodiment of a method for dissolving and smelting waste battery scraps by such a conventional method is as follows.
[종래 방법에 의한 실시예][Example by the conventional method]
금속납 Pb 31%Metal lead Pb 31%
PbO210%PbO 2 10%
PbSO427%PbSO 4 27%
Pb2O 11%Pb 2 O 11%
세파레타 12%Separetta 12%
H2O 7%H 2 O 7%
이상 납의 총함유량 687㎏의 폐납축전지 스크랩 1000㎏을 종래의 방법인 철분 및 탄분에 의한 반사로 제련방법으로 제련하면 620㎏의 금속납이 회수되어 회수율이 90％이고 잔여납은 황산납의 상태로 연화(煙火)된 50㎏금속납 및 미환원된 납의 화합물과 유화납 pbs상태로 광재에 함유 배출되었다. 따라서 종래의 철분 및 탄분에 의한 반사로 제련방법은 작업온도가 높아 납이 쉽게 휘발되어 매연이 발생되고, 회수율이 떨어지며 공해가 발생되는 폐단이 있는 것이다.Smelting 1000kg of waste lead storage battery scrap with a total content of abnormal lead of 687kg by smelting by iron and charcoal, which is a conventional method, recovers 620kg of metal lead and recovers 90%, and the remaining lead is softened to lead sulfate. Compounds of 50 kg metal lead and unreduced lead and lead emulsified pbs were contained in slag. Therefore, the conventional smelting method of the reflection furnace by iron and coal powder has high working temperature and lead is easily volatilized so that smoke is generated, recovery rate is reduced, and pollution is generated.
본 발명은 저융점 유동성의 규산납을 기본으로 하는 프릿트유가 되도록 제련하여 납의 휘발손실을 방지하고 공해요인을 줄이는 방법을 제공하는데 있다. 또한 본 발명의 목적은 광재가 발생되지 않고 폐납축전지 스크랩에 함유된 납을 전량 금속납과 규산납을 기본으로 하는 프릿트유(釉)로 회수하는 방법을 제공하며, 저융점 처리가 가능하므로서 연료소비가 절감되는 방법을 제공하는데 있다.The present invention provides a method of smelting a frit oil based on lead silicate of low melting point fluid to prevent volatilization loss of lead and to reduce pollution. It is also an object of the present invention to provide a method for recovering lead contained in scrap of lead-acid battery scrap without fracturing to frit oil based on the total amount of metal lead and lead silicate. To provide a way to reduce costs.
본 발명의 방법은, 약간의 수분과 경질초자섬유의 세파레타와 격자(格子)의 금속납, 산화납, 황산납 등 활물질인 순수한 재질로 구성된 폐납축전지의 양극판 스크랩을 회전반사로에 투입가열하여 용해가 되면 폐납축전지 스크랩 양의 5％ 탄소분말을 혼합하는 단계, 회전반사로의 온도가 상승되면 폐납축전지 스크랩양의 4％∼7％규산분말을 투입교반하면서 용해하여, 스크랩 격자가 용해되고 산화납, 황산납, 이 환원되어 금속납이 생성되고 일부 규산(SiO2)과 작용하여 저융점 즉 766℃의 PbSiO3가 생성되는 단계로 이루어져 금속납을 생성하고 규산납을 기본으로 하는 프릿트유(釉)를 얻는 것이다.In the method of the present invention, a positive electrode plate scrap of a waste lead storage battery composed of a pure water such as a separeta of hard water and hard superfiber fibers, a metal lead of a lattice, a lead oxide, and a lead sulfate is heated and dissolved in a rotary reflector. When the waste lead storage battery scrap amount is mixed with 5% carbon powder, and when the temperature of the rotary reflection furnace is increased, 4% to 7% silicic acid powder amount of the waste lead storage battery scrap is added and stirred to dissolve, and the scrap lattice is dissolved and lead oxide, Lead sulfate, which is reduced to form metallic lead, and works with some silicic acid (SiO 2 ) to produce PbSiO 3 at low melting point, 766 ℃, to produce metallic lead and frit oil based on lead silicate. To get.
본 발명을 실시예로 더욱 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in detail with reference to Examples.
[실시예]EXAMPLE
금속납 Pb 31%Metal lead Pb 31%
PbO210%PbO 2 10%
PbSO427%PbSO 4 27%
Pb2O 11%Pb 2 O 11%
세파레타 12%Separetta 12%
H2O 9%H 2 O 9%
폐납축전지 스크랩의 재료 1000㎏를 회전반사로에 투입가열 800℃로 가열하고 장입재료가 용해 시작되면 탄소분말 50㎏을 서서히 투입하면서 용해교반하여 납의 산화물을 금속납으로 재생되게 하고, 회전반사로의 온도가 900℃로 상승한 후에 장입재료의 4％∼7％의 입도 20메쉬(mesh)의 규산분말을 서서히 투입하여, SiO2가 PbSO4와 반응 PbSiO3되어 유동성 용제(flux)가 되게 하여 480㎏의 금속납과 280㎏의 규산납을 기본으로 하는 프릿트유(釉)를 얻었다. 본 실시예에 의한 금속납 전체 회수율은 98.8％이었다. 여기서 규산분말을 장입재료인 폐납축전지 스크랩에 대해 4％∼7％혼합하는 것은 폐납축전지 스크랩의 PbSO4의 함유량이 다양하기 때문에 함유량에 따라 4％에서 7％사이에서 조정하는 것이다.1000kg of waste lead storage battery scrap is put into rotary reflector and heated to 800 ℃. When the charged material starts to dissolve, 50kg of carbon powder is slowly added and stirred to dissolve and lead oxide is regenerated into metallic lead. After rising to 900 ° C., 4% to 7% of the particle size 20 mesh silicic acid powder was slowly added, and SiO 2 reacted with PbSO 4 to make PbSiO 3 to become a flux. A frit oil based on lead and 280 kg of lead silicate was obtained. The total lead recovery rate of the present Example was 98.8%. Here, mixing 4% to 7% of the silicic acid powder with respect to the waste lead acid battery scrap as the charging material is adjusted between 4% and 7% according to the content because the content of PbSO 4 in the waste lead acid battery scrap varies.
또한 규산분말을 함유하는 이유는The reason for containing silicate powder is
PbSO4+SiO2+C=PbSiO3+SO2+CO2 PbSO 4 + SiO 2 + C = PbSiO 3 + SO 2 + CO 2
의 반응에 의해 PbSiO3가 생성되도록 하고 생성되는 PbSiO3는 융점 766℃의 저융점이고 유동성이 양호함으로 축전지의 극판에서 금속연으로의 회수를 촉진하고 Pb 및 PbO의 휘발손실 및 공해발생요인을 감소하게 하며 회수율을 높여주게 된다.PbSiO 3 is produced by the reaction of PbSiO 3 , and the resulting PbSiO 3 has a low melting point of 766 ° C and good fluidity, which promotes recovery from the electrode plate of the battery to metal lead and reduces the volatilization loss and pollution factors of Pb and PbO. It will increase the recovery rate.
이와같이 본 발명은 납이 저융점, 유동성의 규산염이 되면서 제련되기 때문에 납의 휘발손실을 방지하고 공해요인을 제거하여 광재가 발생되지 않아 납의 회수율을 증대시키는 특징이 있는 것이다.As described above, the present invention is characterized in that lead is smelted as it becomes a low melting point and fluid silicate, thereby preventing volatilization loss of lead and removing pollutants so that no slag is generated, thereby increasing lead recovery rate.
