技术领域technical field
本发明涉及电化学金属电池技术领域，特别是涉及一种金属空气电池电解液动态循环过滤装置。The invention relates to the technical field of electrochemical metal batteries, in particular to a dynamic circulation filter device for electrolyte of a metal-air battery.
背景技术Background technique
在能源危机日益严峻和生态环境日益恶化的双重危机下，寻找替代传统化石能源的新能源已成为人类生存和发展的必然选择。在此背景下，各种各样的新型绿色能源得到了迅猛的发展，其中化学能源亦受到极大的关注和重视。Under the double crisis of increasingly severe energy crisis and deteriorating ecological environment, finding new energy sources to replace traditional fossil energy sources has become an inevitable choice for human survival and development. In this context, a variety of new green energy has been developed rapidly, among which chemical energy has also received great attention and attention.
在常规高能蓄电池中，锂离子电池具有电压高、能量密度大、制备工艺成熟的特点，但是其价格高昂、高温安全性差以及锂资源不足，很难大规模推广；镍氢电池也受到电池能量密度、成本和资源等问题的制约，无法满足供电需求。氢氧燃料电池性能优异，环境友好，而且氢氧化物在水、植物等中大量存在，不具有原料缺乏问题，但是由于制氢、储氢困难以及催化剂铂全球储量极低等因素，使之在短期内很难实现商业化。Among conventional high-energy storage batteries, lithium-ion batteries have the characteristics of high voltage, high energy density, and mature preparation technology, but their high price, poor high-temperature safety, and insufficient lithium resources make it difficult to promote them on a large scale; nickel-metal hydride batteries are also affected by battery energy density. Due to the constraints of issues such as , cost and resources, it is impossible to meet the power supply demand. Hydrogen-oxygen fuel cells have excellent performance and are environmentally friendly, and hydroxides exist in large quantities in water, plants, etc., so there is no shortage of raw materials. It is difficult to achieve commercialization in the short term.
金属燃料电池是一种以高能量密度金属为燃料的特殊类型燃料电池，具有结构简单、制造成本低、原材料来源丰富、绿色环保和电性能好等优点，是很有发展潜力的新型化学能源。Metal fuel cell is a special type of fuel cell that uses high-energy-density metals as fuel. It has the advantages of simple structure, low manufacturing cost, abundant raw material sources, green environmental protection, and good electrical performance. It is a new type of chemical energy with great development potential.
金属空气电池以活泼金属作为阳极，空气中的氧气作为阴极，通过原电池反应产生电能。金属空气电池利用活泼金属储存的化学能，通过金属氧化，释放能量，无需电网充电。更换电池的负极材料，电池即可再生。Metal-air batteries use active metals as anodes and oxygen in the air as cathodes to generate electricity through primary cell reactions. Metal-air batteries use the chemical energy stored in active metals to release energy through metal oxidation without grid charging. Replace the negative electrode material of the battery, and the battery can be regenerated.
金属燃料电池电解液通常选择中性或碱性溶液，阴极的水分子分解成氢氧根，容易与阳极的金属离子生成胶体，比如，镁燃料电池，阴极的水分子分解成氢氧根，将与阳极的镁离子生成Mg(OH)2胶体，造成电池内部电解液流动性变差，离子迁移困难，从而降低电池的供电功率。Metal fuel cell electrolyte usually chooses neutral or alkaline solution. The water molecules in the cathode decompose into hydroxide ions, which are easy to form colloids with the metal ions in the anode. For example, in magnesium fuel cells, the water molecules in the cathode decompose into hydroxide ions. Mg(OH) 2 colloids are formed with the magnesium ions in the anode, which causes the fluidity of the electrolyte inside the battery to deteriorate and the ion migration is difficult, thereby reducing the power supply of the battery.

本实施例中以镁空电池为例，装置工作过程为：In this embodiment, the magnesium-air battery is taken as an example, and the working process of the device is as follows:
电池箱6内的镁燃料电池单体7反应生成物经过汇流箱5顶面的第一通孔流入汇流箱5内，再经过汇流箱5底面的楔形槽汇聚，之后通过汇流箱出液口流入沉淀管4中，经过滤网，胶体物质被阻隔在过滤网前方，电解液在水泵2的作用下流回电池箱6内的各电池单体7中，通过这种方式实现电解液的动态循环利用，同时也降低了更换电极的清理难度，提高电池的供电效率。The reaction product of the magnesium fuel cell 7 in the battery box 6 flows into the combiner box 5 through the first through hole on the top surface of the combiner box 5, and then converges through the wedge-shaped groove on the bottom surface of the combiner box 5, and then flows into it through the liquid outlet of the combiner box. In the sedimentation pipe 4, the colloidal substances are blocked in front of the filter through the filter, and the electrolyte flows back to each battery cell 7 in the battery box 6 under the action of the water pump 2, in this way the dynamic recycling of the electrolyte is realized , At the same time, it also reduces the cleaning difficulty of replacing the electrode, and improves the power supply efficiency of the battery.
本实施例中，所述水泵2通过多个串联的所述电池单体7供电。In this embodiment, the water pump 2 is powered by a plurality of battery cells 7 connected in series.
水泵2为本发明装置的核心元件，需要精确计算其功率参数，功率参数过小无法满足过滤要求，过大又会增加能耗和发热。The water pump 2 is the core component of the device of the present invention, and its power parameter needs to be accurately calculated. If the power parameter is too small, it cannot meet the filtration requirements, and if it is too large, it will increase energy consumption and heat generation.
水泵2功率的计算过程如下：The calculation process of water pump 2 power is as follows:
首先计算胶体Mg(OH)2的产率，对于一个额定供电电流为I0的镁空气电池，一个电子的电量为c＝1.6×10-9库伦，Na＝6.022×1023阿佛加德罗常数，氢氧化镁的分子量为m＝58，Mg(OH)2的产率为：First calculate the yield of colloidal Mg(OH) 2. For a magnesium-air battery with a rated supply current of I 0 , the charge of one electron is c=1.6×10 -9 Coulomb, Na=6.022×10 23 Avogadro Constant, the molecular weight of magnesium hydroxide is m=58, Mg(OH) The productive rate is:
则水泵2的流量：Q＝λv，其中，λ为滤网的过滤系数，Then the flow rate of the water pump 2: Q=λv, wherein, λ is the filtering coefficient of the filter screen,
得到水泵2的输出压力：P＝μ1Q+μ2Q，其中，μ1为滤网的背压系数，μ2为系统的延程阻力系数。The output pressure of the water pump 2 is obtained: P=μ 1 Q+μ 2 Q, wherein, μ 1 is the back pressure coefficient of the filter screen, and μ 2 is the drag coefficient of the system.
根据水泵2的功率确定为水泵2供电的串联电池单体7的个数，既能满足过滤要求，又将功耗降到最低。According to the power of the water pump 2, the number of battery cells 7 connected in series to supply power to the water pump 2 is determined, which can not only meet the filtering requirements, but also reduce power consumption to a minimum.
