Abstract
사용이 불가능한 폐전지를 완전방전시킨 후 폐전지를 안전하게 파쇄 및 압착시켜 폐기처리할 수 있는 폐전지 처리방법이 개시되어 있다. 폐전지를 분말 형태의 전도체와 비전도체로 이루어진 혼합물에 매립한 상태에서 일정한 시간이 경과하게 되면 전도체를 통한 폐전지의 완전방전에 의해 전지에 존재하는 내부에너지가 0 joule의 상태로 되며, 완전방전시 생길 수 있는 과열, 폭발 등의 위험은 비전도체의 분말을 이용해 막을 수 있다. 상기 완전방전된 전지를 압착기로 압착시켜도 폭발이나 발열 등과 같은 현상이 발생하지 않고 안전하게 폐기처리가 되며 폐전지 처리시 폐수가 발생하지 않아 환경오염이 되지 않는다.Disclosed is a method for treating a waste battery that can be disposed of by completely crushing and compressing the waste battery after completely discharging the unusable waste battery. When a certain time passes while the waste battery is embedded in a mixture of powder-type conductors and non-conductors, the internal energy present in the battery becomes zero joules when the waste battery is completely discharged through the conductors. Risks of overheating, explosions, etc. can be prevented by using nonconducting powder. Even when the fully discharged battery is compressed with a compactor, the battery is safely disposed of without any phenomenon such as explosion or heat generation, and no waste water is generated during waste battery treatment, thereby preventing environmental pollution.
Description
본 발명은 폐전지를 처리하는 방법에 관한 것으로서, 보다 상세하게는 사용이 불가능한 폐전지를 완전방전시킨 후 폐전지를 안전하게 파쇄 및 압착시켜 폐기처리할 수 있는 폐전지 처리방법에 관한 것이다.The present invention relates to a method of treating a waste battery, and more particularly, to a waste battery processing method that can be disposed of by completely crushing and crushing the waste battery after the complete discharge of the unavailable battery.
일반적으로, 전지를 장시간 사용하게 되면 전지의 전기에너지가 소진되어 폐기처리하여야 한다, 상기 폐전지에는 장비를 구동시키기에는 불충분하지만 어느 정도의 내부에너지가 항상 존재하고 있어 폐전지를 폐기처리하는데는 매우 어려운 기술이 요구된다.In general, when the battery is used for a long time, the electric energy of the battery is exhausted and must be disposed of. The waste battery is insufficient to drive the equipment, but some internal energy is always present, which makes it very difficult to dispose of the waste battery. Skill is required.
최근에는 전자기기 및 정보통신장비의 소형화, 첨단화 및 휴대화가 빠르게 진행됨에 따라 이들의 구동전원으로 사용되고 있는 전지의 사용량 또한 급속도로 늘어나고 있다. 따라서 처리해야할 폐전지의 양 또한 늘어날 것으로 예상된다. 그러나 종래의 폐전지를 처리하는 방법으로는 많은 양의 폐전지를 환경오염 없이 안전하게 처리하는데 많은 문제점을 가지고 있으며, 재활용 처리에도 많은 어려운 점을 가지고 있다.Recently, as the miniaturization, advancement, and portability of electronic devices and information and communication equipment are rapidly progressing, the amount of batteries used as driving power sources thereof is also rapidly increasing. Therefore, the amount of waste batteries to be treated is also expected to increase. However, as a conventional method of treating waste batteries, there are many problems in safely treating a large amount of waste batteries without environmental pollution, and there are many difficulties in recycling treatment.
전기에너지가 소진된 폐전지 또는 불량 전지의 경우 전지 내부에 전기에너지가 완전히 소모된 것이 아니라 어느 정도 미량의 에너지가 항상 존재하게 된다. 이러한 폐전지를 함부로 처리할 경우 전지의 내부에 남아 있는 에너지로 인한 발화 또는 폭발의 위험성이 존재한다.In the case of a waste battery or a defective battery that is depleted of electrical energy, a small amount of energy is always present in the battery, not completely consumed. If such waste batteries are disposed of carelessly, there is a risk of ignition or explosion due to the energy remaining inside the batteries.
상기 폐전지의 처리방법으로는 소금물에 전지를 함침시키는 방법과 단순히 폐전지를 매립하여 전지를 폐기하는 방법이 대부분의 전지 업체에서 사용되어지고 있는 방법이다. 상기 매립하여 전지를 폐기하는 방법은 폐전지를 땅에 매립함으로서 폐전지를 처리하는 방법으로서 매립된 상태에서 폭발의 위험이 있을 뿐 만 아니라 토양을 오염시켜 환경문제를 일으킬 수 있으며, 폐전지의 양이 늘어나면 처리가 곤란해지는 문제점을 가지고 있다. 소금물에 함침하는 폐전지 처리방법은 폐전지가 소금물에 함침되어 케이스(case)나 양극 핀(pin)이 부식되는데 많은 시간이 소요될 뿐만 아니라 내부에 전지에너지의 잔량이 많은 폐전지에 소금물이 스며들 경우 급격한 반응으로 인한 폭발의 위험성도 존재한다. 또한 소금물과 전지 케이스, 양극 핀, 전지 내부 물질과의 반응으로 인한 폭발의 위험성도 존재한다. 또한, 소금물과전지 케이스, 양극 핀, 전지 내부의 물질과의 반응으로 폐수가 생성되는 문제점이 있으며, 소금물에 의해 부식된 전지재료는 재활용처리가 불가능하게 된다. 특히 폐수문제는 앞으로 계속 늘어가는 전지 생산량을 고려하면 많은 폐전지를 처리할 경우 심각한 환경 문제가 될 수 있을 것으로 생각된다.As a method of treating the waste battery, a method of impregnating the battery in salt water and a method of disposing the battery by simply burying the waste battery are used in most battery companies. The method of disposing of the battery by landfilling is a method of treating a waste battery by embedding a waste battery in the ground, which not only has a risk of explosion in a landfill state but also contaminates soil and may cause environmental problems. After that, the process becomes difficult. The waste battery treatment method impregnated with salt water takes a lot of time for the case or anode pins to corrode because the waste battery is impregnated with salt water. There is also a risk of explosion due to rapid reaction. There is also a risk of explosion due to the reaction of the brine with the battery case, the positive electrode pins and the material inside the battery. In addition, there is a problem that waste water is generated by the reaction of the salt water and the battery case, the positive electrode pin, the material inside the battery, the battery material corroded by the salt water is impossible to recycle. In particular, the wastewater problem is considered to be a serious environmental problem if many waste batteries are treated in view of the ever-increasing battery production.
본 발명은 상기한 문제점을 해결하기 위하여 안출 된 것으로, 본 발명의 목적은 사용이 불가능한 폐전지를 완전방전시킨 후 폐전지를 안전하게 파쇄 및 압착시켜 폐기처리할 수 있는 폐전지 처리방법을 제공하는데 있다.The present invention has been made to solve the above problems, an object of the present invention is to provide a waste battery processing method that can be disposed of by safely crushing and compacting the waste battery after the complete discharge of the non-use waste battery.

상기와 같은 목적을 달성하기 위하여 본 발명은 분말 또는 과립 상태의 전도체와 비전도체로 이루어지는 혼합물에 전지를 매립시켜 전지에 존재하는 내부에너지를 완전방전시킨 후 파쇄기를 이용하여 전지를 파쇄시킴으로써 폐기시키는 폐전지 처리방법을 제공한다.In order to achieve the above object, the present invention embeds a battery in a mixture consisting of a powder or granular conductor and a non-conductor to completely discharge internal energy present in the battery, and then discards the battery by crushing the battery using a crusher. A battery treatment method is provided.
이하, 본 발명에 따른 폐전지 처리방법의 바람직한 실시예를 첨부된 도면을 참조하여 상술한다. 도 1은 본 발명에 따른 폐전지를 처리하는 장치를 개략적으로 나타낸 도면이고, 도 2는 본 발명에 따른 폐전지를 처리하는 과정을 나타낸 도면으로서, 도시된 바와 같이, 본 발명은 분말 또는 과립 상태의 전도체와 비전도체로 이루어지는 혼합물(20)을 제조하는 제조단계와, 상기 혼합물에 폐전지(10)를 매립시키는 매립단계와, 상기 매립단계에서 전지를 일정시간동안 매립시켜 전지를 완전방전시키는 방전단계와, 상기 완전방전된 전지를 파쇄기(도시 안됨)를 이용하여 전지를 파쇄시킴으로써 폐기시키는 폐기단계를 포함하여 구성된다.Hereinafter, with reference to the accompanying drawings a preferred embodiment of the waste battery processing method according to the present invention will be described in detail. 1 is a view schematically showing an apparatus for treating a waste battery according to the present invention, Figure 2 is a view showing a process for treating a waste battery according to the present invention, as shown, the present invention is a conductor in a powder or granule state And a manufacturing step of manufacturing a mixture 20 consisting of a non-conductor, an embedding step of embedding the waste battery 10 in the mixture, and a discharge step of completely discharging the battery by embedding the battery for a predetermined time in the embedding step; And a disposal step of discarding the completely discharged battery by crushing the battery using a crusher (not shown).
상기 제조단계는 전지를 페기처리하기 전에 내부에너지를 완전방전시킬 수 있는 혼합물을 제조하는 단계로서, 분말 또는 과립 상태인 전도체와 비전도체로 이루어지는 혼합물(20)을 제조한다. 상기 전도체의 저항은 mΩ∼Ω범위를 가지고 있어 전지를 방전시킬 수 있으며, 비전도체는 전지를 완전방전시키는 과정에서 발생할 수 있는 전지의 발화나 파열 등에 의한 안전사고의 발생을 방지할 수 있으며, 상기 전도체와 비전도체의 혼합비율을 조절함으로서 완전방전장치인 혼합물의 저항을 조절할 수 있다.The manufacturing step is to prepare a mixture capable of completely discharging the internal energy before the battery is discarded, to prepare a mixture 20 consisting of a conductor and a non-conductor in the form of powder or granules. The resistance of the conductor has a range of m Ω ~ Ω can discharge the battery, the non-conductor can prevent the occurrence of a safety accident due to the ignition or rupture of the battery that can occur in the process of discharging the battery completely, By controlling the mixing ratio of the conductor and the non-conductor, the resistance of the mixture, which is a complete discharge device, can be controlled.
상기 매립단계는 전도체와 비전도체로 이루어진 분말형태의 혼합물로 이루어진 폐전지 매립지(30)에 폐전지(10)를 매립하게 된다. 상기 전도체와 비전도체는 분말형태를 가지므로 별도의 특별한 장치 없이 전지를 혼합물에 매립하여 완전방전처리를 할 수 있다. 이때 상기 혼합물에는 동시에 많은 폐전지를 매립하여 신속하게 방전시키게 된다.In the embedding step, the waste battery 10 is embedded in the waste battery landfill 30 made of a mixture of powder and conductive materials consisting of a conductor and a non-conductor. Since the conductor and the non-conductor have a powder form, the battery can be completely discharged by embedding the battery in the mixture without any special device. At this time, a lot of waste batteries are buried in the mixture at the same time to discharge quickly.
상기 방전단계에서는 혼합물에 매립된 전지의 내부에 존재하는 내부에너지가 전도체인 카본과 비전도체로서 안정제의 기능을 하는 모래의 낮은 저항에 의해 일정한 시간이 지나면 방전되어 0 joule에 가까운 내부에너지를 갖게 된다. 일반 전자 장비에서 사용되는 전지는 내부에너지가 전자 장비를 구동시키는데 필요한 에너지에 못 미치게 되면 전지의 수명은 끝나게 된다. 그러나 상기 전지의 내부에너지는 어느 정도의 잔량이 존재하는 상태이므로 이러한 내부에너지가 존재하는 상태에서 폐기처리하게되면 사고 발생 및 환경오염의 원인이 된다. 상기 내부에너지가 존재하는 전지를 혼합물에 매립시킨 후 일정한 시간이 경과하게 되면 전지의 내부에너지가 완전방전이 되어 0 joule에 가까운 내부에너지를 갖게 된다.In the discharging step, the internal energy existing in the battery embedded in the mixture is discharged after a certain time due to the low resistance of carbon, which is a conductor, and sand, which functions as a stabilizer, as a non-conductor, and has an internal energy close to 0 joule. . A battery used in general electronic equipment ends its life when the internal energy falls short of the energy required to drive the electronic equipment. However, since the internal energy of the battery is in a state where a certain amount of residual energy exists, disposal of such internal energy in the presence of the battery causes an accident and environmental pollution. After a predetermined time has elapsed since the battery having the internal energy is embedded in the mixture, the internal energy of the battery becomes a complete discharge and has an internal energy close to 0 joule.
상기 폐기단계에서는 방전단계에서 완전방전된 전지를 파쇄기를 이용하여 압착시키므로서 폐기처리한다. 상기 완전방전된 폐전지에 20kg의 쇠덩어리를 지상 20m의 높이에서 낙하시켜 폐전지를 압착시키게 되면 폐전지가 폭발하거나 발열하는 현상이 없이 안전하게 폐기처리된다.In the discarding step, the battery completely discharged in the discharging step is discarded while being compressed using a crusher. When 20kg of iron balls are dropped from the height of 20m above the fully discharged waste battery to compress the waste battery, the waste battery is safely disposed without being exploded or generating heat.
상기 설명에서 알 수 있는 바와 같이, 본 발명은 폐전지를 전도체와 비전도체로 이루어진 혼합물에 매립한 상태에서 일정한 시간이 경과하게 되면 전도체와 비전도체의 특성에 의해 전지에 존재하는 내부에너지가 0 joule의 상태로 완전방전하게 된다. 상기 완전방전된 전지를 압착기로 압착시켜도 폭발이나 발열 등과 같은 현상이 발생하지 않고 안전하게 폐기처리가 되며 폐전지로부터 폐수가 발생하지 않아 환경오염이 되지 않는다. 또한 재활용이 가능한 폐전지의 구성요소를 수거하는데도 기존의 처리법에 비해 가장 유리한 방법이다.As can be seen from the above description, in the present invention, when a predetermined time elapses while a waste battery is embedded in a mixture of a conductor and a non-conductor, the internal energy present in the battery is 0 joule due to the characteristics of the conductor and the non-conductor. It is discharged completely in the state. Even when the fully discharged battery is compressed with a compactor, it is safely disposed of without a phenomenon such as explosion or heat generation, and no waste water is generated from the waste battery, thereby preventing environmental pollution. In addition, it is the most advantageous method compared to the conventional treatment method for collecting the components of the recyclable waste battery.
