Description

리튬배터리용 소화팩{Fire Extinguishing Pack for Lithium Battery }Fire Extinguishing Pack for Lithium Battery}

본 발명은 리튬배터리 보관 및 설치시 리튬배터리 화재진압에 관한 것으로서, 보다 상세하게는 다수의 리튬배터리 셀이나 모듈 또는 배터리팩을 보관하거나 설치 사용하는데 있어, 화재 발생시 연쇄 폭발과 화재확산을 방지하는 리튬배터리용 소화팩에 관한 것이다. The present invention relates to a lithium battery fire suppression during storage and installation of a lithium battery, and more particularly, in the storage or installation and use of a plurality of lithium battery cells, modules, or battery packs, lithium to prevent chain explosion and fire spread in case of fire. It relates to a fire extinguishing pack for batteries.

일반적으로 리튬배터리는 다른 전지에 비해 에너지 밀도 및 출력밀도가 높고,재충전하여 반복적 사용이 가능한 고성능 전지로서 스마트폰, 드론 및 자동차 등 매우 다양한 분야의 전원으로 사용된다. In general, lithium batteries have higher energy density and power density than other batteries, and are high-performance batteries that can be recharged and used repeatedly, and are used as power sources in a wide variety of fields such as smartphones, drones, and automobiles.

한편 리튬배터리에 사용되는 리튬은 본래 불안정한 원소로서 공기중의 수분과 급격하게 반응하여 폭발하기 쉬우며, 전해액은 과열에 따른 화재 위험성이 있다. 이러한 이유 때문에 리튬전지에는 안전보호 회로가 포함되며, 내부를 단단한 플라스틱으로 둘러싸게 된다. 그러나 리튬이차 전지가 열폭주룰 일으키면 다량의 가스가 발생하고 연쇄 폭발을 하게 되어 화재 진압이 매우 어렵게 된다. 더구나 다량의 리튬배터리를 보관하거나 사용하는 곳에서는 화재확산이 우려되므로 화재에 대비한 특별한 대책이 요구된다. 다수의 배터리 보관하거나 사용하는 장소의 경우 금속화재 진압용 소화기를 비치하고 있으나 리튬배터리의 경우 일단 화재가 발생하면 연쇄 폭발의 위험 때문에 기존의 소화 방식에는 한계가 있었다.On the other hand, lithium used in lithium batteries is an inherently unstable element, which reacts rapidly with moisture in the air and is easy to explode, and the electrolyte has a risk of fire due to overheating. For this reason, a lithium battery includes a safety protection circuit, and the inside is surrounded by hard plastic. However, when a lithium secondary battery causes thermal runaway, a large amount of gas is generated and a chain explosion occurs, making it very difficult to extinguish a fire. Moreover, in places where large amounts of lithium batteries are stored or used, there is a concern about fire spread, so special measures against fire are required. In the case of storage or use of a large number of batteries, fire extinguishers for extinguishing metal fires are provided, but in the case of lithium batteries, there is a limit to the existing fire extinguishing method due to the risk of chain explosion once a fire occurs.

본 발명은 상기와 같은 종래 문제점을 해결하기 위한 것으로서, 본 발명의 목적은 다수의 리튬배터리를 안전하게 보관하고 사용하는데 있어, 화재 발생시 해당 배터리에 대한 초기 화재진압이 가능한 리튬배터리용 소화팩을 제공하는데 있다.The present invention is to solve the conventional problems as described above, and an object of the present invention is to safely store and use a plurality of lithium batteries, and to provide a fire extinguishing pack for a lithium battery capable of initial fire suppression for a corresponding battery in the event of a fire. have.

본 발명은 리튬배터리의 셀단위, 모듈 및 배터리팩의 주변에 간단하고 편리하게 팩의 형태를 단순하게 적층만 함으로서 안전을 담보하고 화재발생시 초기 진압이 가능하여 화재로 인한 인명 피해나 재산손실을 대폭 줄일 수 있는 리튬배터리용 소화팩을 제공하는데 있다.The present invention guarantees safety by simply and conveniently stacking the shape of the pack around the cell unit, module, and battery pack of a lithium battery, and enables initial extinguishing in the event of a fire, thereby greatly reducing personal injury or property loss due to fire. It is to provide a fire extinguishing pack for lithium batteries that can be reduced.

이러한 목적을 달성하기 위한 본 발명은, 적층이 가능한 소화용 밀폐상자팩에 리튬배터리의 화재시 소화가 가능한 금속화재 진압용 분말소화약제가 채워져 있다. 화재 발생시 소화약제가 소화팩으로부터 용이하게 쏟아지도록 밀폐상자의 각 면에 다수의 구멍이 있으며, 이 구멍은 평상시 가연성시트로 막혀 있는 밀폐상자팩이며, 리튬배터리 화재시 그 불꽃이나 열기로 가연성시트가 녹아 소화약제가 구멍을 통해 주변으로 쏟아지게 된다. 리튬배터리가 보관되거나 설치된 곳의 리튬배터리의 주변을 약 10~15센티미터의 두께로 골고루 덮을 수 있도록 다수의 리튬배터리용 소화팩을 배치하여 리튬배터리 화재시 소화약제가 배터리 주변을 골고루 덮어 질식소화 내지 화재의 확산을 막아 리튬배터리의 화재진압을 초기에 효과적으로 달성할 수 있다.In the present invention for achieving this object, a powder extinguishing agent for extinguishing metal fires capable of extinguishing a fire of a lithium battery is filled in a stackable fire extinguishing sealed box pack. In the event of a fire, there are a number of holes on each side of the sealed box so that the extinguishing agent can be easily poured from the fire extinguishing pack. These holes are normally closed with a flammable sheet. In case of a fire with a lithium battery, the flammable sheet It melts and the extinguishing agent is poured into the surroundings through the hole. A number of fire extinguishing packs for lithium batteries are arranged to cover the area of the lithium battery where the lithium battery is stored or installed in a thickness of about 10 to 15 cm. By preventing the spread of fire, fire suppression of lithium batteries can be effectively achieved early.

본 발명은 상기한 바와 같은 특징들에 의해, 큰 비용을 들이지 않고도 다수의 리튬배터리를 보관 및 사용하는 곳에 리튬배터리용 소화팩을 설치하여 화재 발생시 화재를 초기에 원천적으로 진압하고 확산을 방지함으로서 경제적 손실과 인명피해를 최소화 하는 장점을 가진다.The present invention is economical by installing a fire extinguishing pack for lithium batteries in a place where a number of lithium batteries are stored and used without incurring a large cost by the above-described features to extinguish a fire initially and prevent its spread. It has the advantage of minimizing loss and personal injury.

또한, 별도의 포터블 소화기를 설치하지 않고도 초기 화재진압을 효과적으로 수행하는 소화기능과 안전한 보관기능을 동시에 가지고 있어 안전을 담보할 수 있으며 경제적이다.In addition, it has both a fire extinguishing function that effectively extinguishes the initial fire without installing a separate portable fire extinguisher and a safe storage function, thus ensuring safety and economical.
