Description
技术领域technical field
本发明涉及公共安全消防领域，具体涉及一种酸铁锂电池微型储能装置消防***及灭火方法。The invention relates to the field of public safety fire protection, in particular to a fire protection system and a fire extinguishing method for a micro energy storage device of an iron-acid lithium battery.
背景技术Background technique
能源结构低碳化正逐渐成为全世界能源可持续发展的目标，储能***作为关键元素，在新能源接入、削峰填谷、平滑负荷、调频等方面具有积极的作用。磷酸铁锂电池微型储能装置于近期兴起，是专门为家庭打造的新型储能产品，可用容量是3kWh，其中的单相产品，配合用户的光伏***可实现新能源发电自用；三相产品则主要是针对新能源发电自用以及调频市场。The low-carbon energy structure is gradually becoming the goal of sustainable energy development around the world. As a key element, energy storage systems play an active role in new energy access, peak shaving and valley filling, load smoothing, and frequency regulation. Lithium iron phosphate battery micro-energy storage devices have emerged recently. They are new energy storage products specially designed for households. Mainly for self-use of new energy power generation and frequency regulation market.
因为该微型储能装置采用的是磷酸铁锂电池模组，运行过程中会因为过充、过热及机械碰撞等原因，造成磷酸铁锂电池模组发生热失控，继而起火燃烧引发火灾，造成经济损失甚至人员伤亡。热失控指的由各种诱因引发的链式反应现象，热失控散发出的大量热量和有害气体会引起电池着火和***，电池热失控往往从电池电芯内的负极膜分解开始，继而隔膜分解熔化，导致负极与电解液发生发应，随之正极和电解质都会发生分解，从而引发大规模的内短路，造成了电解液燃烧，进而蔓延到其他电芯，造成了严重的热失控，让整个电池组产生自燃。锂电池过热的原因来自于电池的选型和热设计的不合理，或者外短路导致电池的温度升高、电缆的接头松动等，设计缺陷来自于电池设计和电池管理两个方面。过充触发的热失控，是电池管理***本身对过充电的电路安全功能缺失，导致电池管理***失控却还在充电导致的，或者是电池老化导致一致性缺乏，针对这类过充电的原因，解决办法首先是查找充电机的故障，通过充电机的完全冗余来解决；其次是看电池管理，监控每一节电池的电压。碰撞触发热失控的办法就是做好电池的安全保护设计。但是目前还没有针对所述微型储能装置的消防技术方案和灭火设施。Because the micro-energy storage device uses a lithium iron phosphate battery module, overcharging, overheating, and mechanical collisions will cause thermal runaway of the lithium iron phosphate battery module during operation, which will cause a fire and cause economic damage. losses and even casualties. Thermal runaway refers to a chain reaction phenomenon caused by various incentives. The large amount of heat and harmful gases emitted by thermal runaway will cause the battery to catch fire and explode. The thermal runaway of the battery often begins with the decomposition of the negative electrode film in the battery cell, and then the decomposition of the diaphragm Melting causes the negative electrode to react with the electrolyte, and then the positive electrode and electrolyte will decompose, causing a large-scale internal short circuit, causing the electrolyte to burn, and then spreading to other batteries, causing serious thermal runaway, making the entire battery The battery pack spontaneously ignites. The reason for the overheating of the lithium battery comes from the unreasonable selection of the battery and the thermal design, or the external short circuit causes the temperature of the battery to rise, the cable connector is loose, etc. The design defect comes from two aspects of battery design and battery management. The thermal runaway triggered by overcharging is caused by the lack of safety function of the battery management system itself for the overcharging circuit, which leads to the loss of control of the battery management system but still charging, or the lack of consistency caused by the aging of the battery. For this type of overcharging reasons, The solution is first to find the fault of the charger and solve it through the complete redundancy of the charger; secondly, to look at the battery management and monitor the voltage of each battery. The way to trigger thermal runaway due to collision is to do a good job in the safety protection design of the battery. But there is no fire-fighting technical scheme and fire-fighting facilities for the micro-energy storage device at present.
申请号为202010170603.1的中国申请专利中，提出了一种抽屉式模块消防技术方案，通过设置有多层盒体、多级管道，利用多级封堵结构隔断灭火区域与电池区域，经过封堵后等待灭火抑制剂进入后实现灭火；但是上述方案中，多层盒体与多级封堵只是起到了阻碍火势蔓延的作用，但是当火势增大或者过热、过充效果明显时，难以迅速灭火，并且多层材料增加了成本，不适用于家庭范围采用与维护。申请号为202210319583.9的中国申请专利中，提出了一种全氟己酮作为灭火抑制剂的消防技术方案，全氟己酮灭火剂是一种新型哈龙和HFCs类灭火剂的优良替代品，具有良好的抑制火灾的能力，而且不会对保护对象产生危害、损害作用小，并具有一定的冷却效能；但是全氟己酮适用于热失控尚有争议，且相关设计规范缺乏，技术参数不足，若不能保持一定灭火剂浓度和足够的浸渍时间，全氟己酮无法抑制磷酸铁锂电池的热失控。申请号CN201811557894.9的中国申请专利中提出了一种扑救锂离子储能装置火灾的灭火抑制剂用量筛选方法，通过灭火实验，确定灭火抑制剂用量，筛选出一定空间体积内扑灭火灾并使装置表面温度达到期望值所需的灭火抑制剂用量，进而预估保护区灭火剂用量；但是其灭火测试情景仅停留在单体电池火灾场景，缺乏适用于家庭环境下的储能装置级别的火灾灭火的场景试验，并且由于储能装置中电池的不一致性，难以有效抑制热失控现象的发生，在家庭使用场景下危险性大幅增加，难以确保发生火情时灭火抑制剂进行灭火的有效性。In the Chinese patent application with the application number 202010170603.1, a drawer-type module fire protection technology scheme is proposed. By setting up multi-layer boxes and multi-level pipelines, the multi-level sealing structure is used to isolate the fire-extinguishing area and the battery area. Waiting for the fire extinguishing agent to enter to extinguish the fire; however, in the above scheme, the multi-layer box and multi-stage sealing only play a role in hindering the spread of the fire, but when the fire increases or the effect of overheating and overcharging is obvious, it is difficult to quickly extinguish the fire. And the multi-layer material increases the cost, which is not suitable for family-wide adoption and maintenance. In the Chinese patent application with the application number 202210319583.9, a fire-fighting technical scheme using perfluorohexanone as a fire extinguishing inhibitor is proposed. Perfluorohexanone fire extinguishing agent is an excellent substitute for a new type of halon and HFCs fire extinguishing agent. It has a good ability to suppress fire, and will not cause harm to the protected object, has little damage, and has a certain cooling effect; however, it is still controversial that perfluorohexanone is suitable for thermal runaway, and there is a lack of relevant design specifications and insufficient technical parameters. If a certain fire extinguishing agent concentration and sufficient immersion time cannot be maintained, perfluorohexanone cannot suppress the thermal runaway of lithium iron phosphate batteries. The Chinese patent application with the application number CN201811557894.9 proposes a screening method for the amount of fire extinguishing inhibitor used to extinguish the fire of a lithium ion energy storage device. Through the fire extinguishing experiment, the amount of fire extinguishing inhibitor is determined, and the fire is extinguished in a certain space volume and the device is selected. The amount of fire extinguishing agent required for the surface temperature to reach the expected value, and then estimate the amount of fire extinguishing agent in the protected area; however, the fire extinguishing test scenario only stays in the single battery fire scene, and lacks fire extinguishing methods suitable for energy storage devices in the home environment. Scenario test, and due to the inconsistency of the battery in the energy storage device, it is difficult to effectively suppress the occurrence of thermal runaway, and the danger increases greatly in the household use scenario, and it is difficult to ensure the effectiveness of the fire extinguishing agent in the event of a fire.
即，现有技术中对于磷酸铁锂电池微型储能装置并未提出一种解决因为微型储能装置运行过程中过充、过热及机械碰撞等原因，造成磷酸铁锂电池模组发生热失控，继而起火燃烧引发火灾，造成经济损失甚至人员伤亡的方案，在所述磷酸铁锂电池微型储能装置应用于家庭范围内时，难以贴近家庭日常使用，存在成本高、灭火效果差的技术问题。That is, in the prior art, no solution has been proposed for the lithium iron phosphate battery micro-energy storage device. Because of overcharging, overheating, and mechanical collisions during the operation of the micro-energy storage device, the thermal runaway of the lithium iron phosphate battery module occurs. Then, the scheme of burning and causing a fire, causing economic losses or even casualties, when the lithium iron phosphate battery micro energy storage device is applied in the family range, it is difficult to be close to the daily use of the family, and there are technical problems of high cost and poor fire extinguishing effect.
