Description

电化学脱嵌控制方法、系统、控制单元、设备及存储介质 技术领域
本文涉及电化学技术领域，具体而言，涉及一种电化学脱嵌控制方法、系统、控制单元、设备及存储介质。
背景技术
近年来，随着新能源汽车和电子类产品的快速发展，锂及其化合物得到广泛应用，使得全球对锂资源需求量剧增，锂资源的开发利用也越来越受重视，而盐湖卤水中含有大量锂资源，因此，盐湖卤水选择性提锂成为获取锂的主要途径，如何高效地从盐湖卤水中提取锂也成为研究热点。
通常，盐湖提锂方法有沉淀法、碳化法、煅烧法、溶液萃取法、电化学提取法等，在这些方法中，电化学提锂指将盐湖卤水放置在有多个脱嵌单元的电化学脱嵌槽中，通过各脱嵌单元来使盐湖卤水发生化学反应，从而获取出盐湖卤水中的锂，电化学提锂因其具有高效节能、安全环保等特点而备受关注。
现有技术中，一种电化学脱嵌槽的控制方法是将多个脱嵌单元并联，通过电源为并联的多个脱嵌单元供电，以使各脱嵌单元的供电电压一致，这种方式虽然可以解决可靠供电问题，但是存在脱锂效率低，电化学脱嵌槽制作成本高的问题。也有将多个脱嵌单元串联连接，用单电源设备以先恒流后恒压的模式为串联的多个脱嵌单元供电。但是串联的供电方式，需要每个脱嵌单元严格一致以确保各脱嵌单元同时达到安全工作电压，以使提锂效率达到最大，而实际制作工艺中难以保证每个脱嵌单元完全一致，因此，用单电源设备以恒流模式为串联的多个脱嵌单元供电时，随着提锂时间的增长，在其他脱嵌单元正常工作时，某一个脱嵌单元上的电压会超过其安全工作电压，该脱嵌单元就会处于非正常工作状态，为了避免该脱嵌单元损坏，随即，整个电化学脱嵌槽的供电模式会调整为单电源设备恒压供电，导致与其串联的其他脱嵌单元不能继续在恒流供电过程中发挥最大提锂效能。

具体实施方式
为使本文实施例的目的、技术方案和优点更加清楚，下面将结合本文实施例中的附图， 对本文实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本文一部分实施例，而不是全部的实施例。
通常在此处附图中描述和示出的本文实施例的组件可以以各种不同的配置来布置和设计。因此，以下对在附图中提供的本文的实施例的详细描述并非旨在限制要求保护的本文的范围，而是仅仅表示本文的选定实施例。基于本文的实施例，本领域技术人员在没有做出创造性劳动的前提下所获得的所有其他实施例，都属于本文保护的范围。
应注意到：相似的标号和字母在下面的附图中表示类似项，因此，一旦某一项在一个附图中被定义，则在随后的附图中不需要对其进行进一步定义和解释。
本文针对的是电化学脱嵌槽的脱嵌控制方法，现有的电化学脱嵌控制方法有两种，一种是将多个脱嵌单元并联连接，用多个电源设备分别为多个脱嵌单元恒压供电，这种方式虽然可以解决可靠供电问题，但是存在脱锂效率低、电化学脱嵌槽制作成本高的问题，于是，提出了另一种控制方法：使用单一电源设备，以先恒流后恒压的模式为多个串联连接的脱嵌单元供电，以解决恒压供电导致的脱锂效率低、电化学脱嵌槽制作成本高的问题。
参照图5，0-t1过程中，电源设备为脱嵌单元的提供的供电电流为恒流电流，随着时间的进行，在t1时刻，脱嵌单元的工作电压上升到预设电压阈值，此时转为恒压输出模式，保持脱嵌提锂反应直到电流值为零。即，在t1时，电源设备的供电模式由恒流供电切换为恒压供电，t1-t2为恒压供电，在这一阶段，极化电阻逐渐变大，电流就会变小，则锂离子的移动速率越来越慢，脱嵌速度逐渐降低，直至t2时刻电流为零，在t2时刻停止用脱嵌单元进行电化学脱嵌。
但若在单电源设备以恒流模式为串联的多个脱嵌单元供电时，各脱嵌单元不能完全一致，某一个脱嵌单元上的电压会超过其安全工作电压，随即，为了避免该脱嵌单元上的电压超过其安全工作电压而被损坏，整个电化学脱嵌槽的供电模式会调整为单电源设备恒压供电，从而导致与该脱嵌单元串联的其他脱嵌单元也不能继续在恒流状态正常工作，导致整个电化学脱嵌槽的提锂效率低。基于此，本文提供了一种电化学脱嵌控制方法及电化学脱嵌槽系统。
另外，本文中使用的流程图示出了根据本文的一些实施例实现的操作。应该理解，在不冲突的情况下，本文的实施例中的特征可以相互结合，流程图的操作可以不按顺序实现，没有逻辑的上下文关系的步骤可以反转顺序或者同时实施。此外，本领域技术人员在本文内容的指引下，可以向流程图添加一个或多个其他操作，也可以从流程图中移除一个或多个操作。
以下结合多个附图通过多个示例对本文提供的电化学脱嵌控制方法及电化学脱嵌槽系 统进行具体的示例说明。
首先，结合图1-图3对本文提供的电化学脱嵌槽系统进行说明。
图1为一些实施例提供的电化学脱嵌槽系统的结构示意图，图2为一些实施例提供的电化学脱嵌槽的结构示意图，如图1和图2所示，一些实施例提供了一种电化学脱嵌槽系统，包括：电化学脱嵌槽1、供电模块2、电压采集单元3、向心搅拌器4、控制单元5。
其中，电化学脱嵌槽包括多个脱嵌单元，每个脱嵌单元具有容纳待脱嵌液体的容置腔，脱嵌单元用于使待脱嵌液体发生化学反应以提取出锂，容置腔用于容纳待脱嵌液体；供电模块连接多个脱嵌单元的接线端，用于为多个串联的脱嵌单元供电；电压采集单元的输入端与多个脱嵌单元的接线端连接，用于采集多个脱嵌单元的工作电压；多个脱嵌单元的容置腔内分别设置有至少一个向心搅拌器，用于搅拌容置腔内的待脱嵌液体；电压采集单元的输出端连接控制单元，用于将采集到的多个脱嵌单元的工作电压的信息发送至控制单元；控制单元还连接供电模块和多个向心搅拌器；控制单元用于执行下述的电化学脱嵌控制方法，实现对电压采集单元、多个向心搅拌器、以及供电模块的控制。
需要说明的是，在本实施例中，待脱嵌液体例如可以为含有锂的盐湖卤水，电化学脱嵌槽中的每个脱嵌单元都可以单独用于从待脱嵌液体中提取锂，电化学脱嵌槽设置多个脱嵌单元，是为了提高脱嵌效率；在本实施例中，采用先恒流后恒压的供电方式，先为多个脱嵌单元恒流供电，以使多个脱嵌单元的电压值不断升高，当电压值快要达到安全工作电压时，转换为恒压供电，使脱嵌单元的工作电压维持在较高值，充分发挥对盐湖卤水的脱嵌效能；电压采集单元可以为包含多个电压采集点的一个电压采集器，可以将各电压采集点分别接到串联的脱嵌单元的接线端，采集多个脱嵌单元的工作电压；每个脱嵌单元的容置腔内的向心搅拌器的数量大于等于1，也即每个脱嵌单元的容置腔内至少有一个向心搅拌器。
在一些实施例中，每个脱嵌单元可以仅包括电极板对；或者，每个脱嵌单元包括并联的多个电极板对组成的电极板组；或者，每个脱嵌单元包括具有多个电极板组的脱嵌槽，每个电极板组由并联的多个电极板对组成。其中，每个电极板对都可以单独用于从待脱嵌液体中提取锂。
图3为一些实施例提供的又一电化学脱嵌槽系统的结构示意图，如图3所示，在可能的实现示例中，电化学脱嵌槽系统还包括多个报警模块，多个报警模块连接控制单元，报警模块用于在脱嵌单元的工作电压大于或等于预设电压阈值时进行报警，以提醒工作人员注意。每个报警模块分别对应一个脱嵌单元，当控制单元检测到某一脱嵌单元的工作电压大于或等于其对应的预设电压阈值时，向该脱嵌单元对应的报警模块发送报警控制信号，基于报警控制信号，报警模块即可报警。
需要说明的是，报警模块可以为声音和/或灯光报警装置，或者其他类型的报警装置，只要报警模块发出的报警信息能被工作人员及时获知即可。
在一些实施例中，除上述实施例提供的电压采集单元为包含多个电压采集点的一个电压采集器之外，电压采集单元还可以包括多个电压采集器，多个电压采集器的输入端分别与多个脱嵌单元的接线端连接，多个电压采集器的输出端分别连接控制单元。
综上，采用本实施例提供的电化学脱嵌槽系统，控制单元可以接收电压采集单元发送的多个脱嵌单元的工作电压的信息，并基于该信息，确定每个脱嵌单元的当前工作电压是否大于或等于预设电压阈值，当某一脱嵌单元的工作电压大于或等于其对应的预设电压阈值时，将该脱嵌单元作为目标脱嵌单元，并控制目标脱嵌单元中设置的目标向心搅拌器对目标脱嵌单元的容置腔内的待脱嵌液体进行搅拌，从而使目标脱嵌单元的极化电阻减小，目标脱嵌单元的工作电压即可随之减小，使得目标脱嵌单元的工作电压不会超过其预设安全工作电压，可以继续发挥最大效能，增加了目标脱嵌单元发挥最大效能的时间，也避免为了保护目标脱嵌单元而将单电源设备切换为恒压供电，使得与其串联的其他脱嵌单元不能继续在恒流模式下发挥最大提锂效能的问题，提高了整个电化学脱嵌槽的提锂效率。
其中，脱嵌单元的预设电压阈值小于预设安全工作电压，可以保证脱嵌单元的当前工作电压大于预设电压阈值时，也不会超过其预设安全工作电压，避免造成脱嵌单元损坏；预设电压阈值为预先获取的数值，在实际操作中，可以根据脱嵌单元的各工作参数来预先获取预设电压阈值。
以下结合图4和图5对本文提供的电化学脱嵌控制方法进行说明。
图4为一些实施例提供的电化学脱嵌控制方法的流程示意图，该方法应用于上述电化学脱嵌槽系统中的控制单元，如图4所示，该方法包括：
S401、控制供电模块以恒流模式为电化学脱嵌槽系统的多个脱嵌单元进行供电。
图5为一些实施例提供的脱嵌单元工作时产生的效能示意图，如图5所示，本文采用先恒流后恒压的供电方式，先恒流供电使多个脱嵌单元的电压值不断升高，当电压值快要达到安全工作电压时，转换为恒压供电，从而使脱嵌单元充分发挥效能。
如图5所示，0-t1为恒流供电，t1-t2为恒压供电，恒压供电时，电流不断减小至0。0-t1阶段比t1-t2阶段的电流大，锂离子的移动速率更快，脱嵌速度快；t1-t2阶段恒压供电，极化电阻逐渐变大，电流就会变小，则锂离子的移动速率越来越慢，脱嵌速度逐渐降低。本实施例是通过增加恒流供电的持续时间，即增加脱嵌单元处于0-t1阶段的时间，以减小脱嵌所需单位时间，从而提高脱嵌效率的目的。
因此，在电化学脱嵌槽开始工作时，控制单元需要控制供电模块以恒流模式为电化学脱嵌槽系统的多个脱嵌单元进行供电，恒流的电流值大小由实际需求决定，在此不做限定。
S402、获取电压采集单元采集的多个脱嵌单元的工作电压。
在供电模块以恒流模式为电化学脱嵌槽系统的多个脱嵌单元进行供电的同时，多个脱嵌单元的工作电压也不断升高，由上述实施例所述可知，电压采集单元的输入端与多个脱嵌单元的接线端连接，可以采集多个脱嵌单元的工作电压，电压采集单元的输出端与控制单元连接，可以将采集到的工作电压发送至控制单元，因此，在供电模块以恒流模式为电化学脱嵌槽系统的多个脱嵌单元进行供电的同时，控制单元可以实时获取电压采集单元采集的多个脱嵌单元的工作电压。
S403、根据多个脱嵌单元的工作电压和对应的预设电压阈值，从多个脱嵌单元中确定工作电压大于或等于对应的预设电压阈值的脱嵌单元为目标脱嵌单元。
在控制单元根据步骤S402实时获取到多个脱嵌单元的工作电压之后，控制单元可以根据多个脱嵌单元的工作电压和多个脱嵌单元各自对应的预设电压阈值，对各脱嵌单元的当前工作电压进行检测，当某一脱嵌单元的工作电压大于或等于其对应的预设电压阈值时，将该脱嵌单元作为目标脱嵌单元，其中，每个脱嵌单元对应的预设电压阈值小于每个脱嵌单元的预设安全工作电压。
可以理解为，在目标脱嵌单元的容置腔内的待脱嵌液体中，各处的溶液含锂浓度不同，当浓度差过大时，脱嵌单元的电阻值过大，在恒流前提下，目标脱嵌单元的工作电压即将超过其安全工作电压，存在损坏风险，因此，需要从多个脱嵌单元中确定工作电压大于或等于对应的预设电压阈值的脱嵌单元为目标脱嵌单元，对目标脱嵌单元采取措施以使其工作电压降低。其中，目标脱嵌单元的预设电压阈值小于目标脱嵌单元的预设安全工作电压。
例如，当脱嵌单元为电极板对时，用电极板对提锂，锂离子会沉积在电极板对的正极，负极周围的锂离子浓度小于正极，会产生浓度差，使电极板对的极化电阻增大，由于电流恒定，电阻增大会导致电极板对的工作电压升高，当为多个电极板对串联供电时，在其他电极板对正常工作时，由于多个电极板对不能完全一致，某个电极板对的工作电压会超过其预设安全工作电压，这时，可以对该电极板对采取降压措施，从而延长电极板对发挥最大效能的时间。
S404、控制目标脱嵌单元中设置的目标向心搅拌器对目标脱嵌单元的容置腔内的待脱嵌液体进行搅拌，以降低目标脱嵌单元的工作电压。
当根据步骤S403确定目标脱嵌单元后，由于目标脱嵌单元的工作电压与待脱嵌液体的浓度正相关，则，可以在每个脱嵌单元的容置腔内设置至少一个向心搅拌器，且向心搅拌器与控制单元连接，当目标脱嵌单元的工作电压大于或等于对应的预设电压阈值，控制单元可以控制目标脱嵌单元中设置的目标向心搅拌器对目标脱嵌单元的容置腔内的待脱嵌液体进行搅拌，从而使容置腔内的待脱嵌液体的浓度差降低，减小极化电阻值，以降低目标 脱嵌单元的工作电压。
可选的，目标向心搅拌器可以以固定转速对目标脱嵌单元的容置腔内的待脱嵌液体进行搅拌，也可以以阶梯型转速对目标脱嵌单元的容置腔内的待脱嵌液体进行搅拌。阶梯型转速指先以较快的转速进行搅拌，再以较慢的转速进行搅拌，或先以较慢的转速进行搅拌，再以较快的转速进行搅拌。
综上，本实施例提供了一种电化学脱嵌控制方法，该方法应用于电化学脱嵌槽系统中的控制单元，该方法包括控制供电模块以恒流模式为电化学脱嵌槽系统的多个脱嵌单元进行供电；获取电压采集单元采集的多个脱嵌单元的工作电压；根据多个脱嵌单元的工作电压和对应的预设电压阈值，从多个脱嵌单元中确定工作电压大于或等于对应的预设电压阈值的脱嵌单元为目标脱嵌单元；控制目标脱嵌单元中设置的目标向心搅拌器对目标脱嵌单元的容置腔内的待脱嵌液体进行搅拌。采用本实施例提供的电化学脱嵌控制方法，在以恒流供电为串联的多个脱嵌单元供电时，当目标脱嵌单元的工作电压即将超过其预设安全工作电压时，控制单元可以控制目标脱嵌单元对应的目标向心搅拌器对该脱嵌单元对应的容置腔内的待脱嵌液体进行搅拌，从而使目标脱嵌单元的极化电阻减小，目标脱嵌单元的工作电压即可随之减小，使得目标脱嵌单元的工作电压不会超过其预设安全工作电压，可以继续发挥最大效能，增加了目标脱嵌单元发挥最大效能的时间，也避免为了保护目标脱嵌单元而将单电源设备切换为恒压供电，使得与其串联的其他脱嵌单元不能继续在恒流模式下发挥最大提锂效能的问题，提高了整个电化学脱嵌槽的提锂效率。
本文一些实施例还提供了另一种电化学脱嵌控制方法，在可能的实现示例中，在控制单元控制目标脱嵌单元中设置的目标向心搅拌器对目标脱嵌单元的容置腔内的待脱嵌液体进行搅拌的同时，电压采集单元实时采集目标脱嵌单元的工作电压，并将采集到的信息发送至控制单元，控制单元对接收到的信息进行检测，当控制单元监测到目标脱嵌单元的工作电压小于对应的预设电压阈值时，则控制目标向心搅拌器停止对目标脱嵌单元的容置腔内的待脱嵌液体进行搅拌。
在一些实施例中，在步骤S404中，控制目标脱嵌单元中设置的目标向心搅拌器对目标脱嵌单元的容置腔内的待脱嵌液体进行搅拌，还可以包括方法1-3中的一项或多项，方法1-3如下：
1、对目标脱嵌单元在预设历史时间段内工作电压大于或等于对应预设电压阈值的次数进行查询，若目标脱嵌单元在预设历史时间段内工作电压大于或等于对应预设电压阈值的次数小于或等于预设次数阈值，则控制目标脱嵌单元中设置的目标向心搅拌器对目标脱嵌单元的容置腔内的待脱嵌液体进行搅拌；若目标脱嵌单元在预设历史时间段内工作电压大于或等于对应预设电压阈值的次数大于预设次数阈值，则控制目标向心搅拌器停止对目标 脱嵌单元的容置腔内的待脱嵌液体进行搅拌，并控制供电模块以恒压模式为目标脱嵌单元进行供电。其中，预设次数阈值为预设数值，预设历史时间段为当前时间之前的一段预设时间，可以根据实际需求设定预设次数阈值和预设历史时间段的数值，例如可以为过去1小时，在此不对预设次数阈值和预设历史时间段做限定。
采用该方法，若目标脱嵌单元在预设历史时间段内工作电压大于或等于对应预设电压阈值的次数大于预设次数阈值，控制目标向心搅拌器停止对目标脱嵌单元的容置腔内的待脱嵌液体进行搅拌，并控制供电模块以恒压模式为目标脱嵌单元进行供电，可以避免多次搅拌仍无法降低目标脱嵌单元的工作电压，避免了目标脱嵌单元的工作电压超过其预设安全电压的风险。
以预设次数阈值为1次为例进行说明：当目标脱嵌单元的工作电压第一次大于或等于其对应的预设电压阈值时，控制单元控制其对应的目标向心搅拌器对目标脱嵌单元的容置腔内的待脱嵌液体进行搅拌，以使目标脱嵌单元的工作电压降低至预设电压阈值以下，之后，随着时间推移，目标脱嵌单元的工作电压第二次大于或等于其对应的预设电压阈值，这时，可以认为目标脱嵌单元的容置腔内的待脱嵌液体的浓差已经达到最小值，继续搅拌目标脱嵌单元的容置腔内的待脱嵌液体已经不能降低目标脱嵌单元的工作电压，则控制目标向心搅拌器停止对目标脱嵌单元的容置腔内的待脱嵌液体进行搅拌，并控制供电模块以恒压模式为目标脱嵌单元进行供电。
2、在目标向心搅拌器开始对目标脱嵌单元的容置腔内的待脱嵌液体进行搅拌时，统计目标向心搅拌器的工作时长，若目标向心搅拌器的工作时长小于预设时长，则控制目标向心搅拌器继续对目标脱嵌单元的容置腔内的待脱嵌液体进行搅拌；若目标向心搅拌器的工作时长大于或等于预设时长，则控制目标向心搅拌器停止对目标脱嵌单元的容置腔内的待脱嵌液体进行搅拌，并控制供电模块以恒压模式为目标脱嵌单元进行供电。其中，预设时长为预设数值，在此不对预设时长的数值做限定。
采用该方法，当目标向心搅拌器的工作时长大于或等于预设时长时，控制目标向心搅拌器停止对目标脱嵌单元的容置腔内的待脱嵌液体进行搅拌，并控制供电模块以恒压模式为目标脱嵌单元进行供电，可以预防单次长时间搅拌依然无法降低目标脱嵌单元的工作电压，避免了目标脱嵌单元的工作电压超过其预设安全电压的风险。
以预设时长为20分钟为例进行说明：在目标向心搅拌器开始对目标脱嵌单元的容置腔内的待脱嵌液体进行搅拌时，统计目标向心搅拌器的工作时长，若目标向心搅拌器的工作时长大于或等于20分钟，控制单元控制目标向心搅拌器停止对目标脱嵌单元的容置腔内的待脱嵌液体进行搅拌，并控制供电模块以恒压模式为目标脱嵌单元进行供电。
3、在目标向心搅拌器开始对目标脱嵌单元的容置腔内的待脱嵌液体进行搅拌时，实时 采集目标脱嵌单元的工作电压，若目标脱嵌单元的工作电压小于预设安全工作电压，控制目标向心搅拌器继续对目标脱嵌单元的容置腔内的待脱嵌液体进行搅拌；若目标脱嵌单元的工作电压大于或等于预设安全工作电压，则控制目标向心搅拌器停止对目标脱嵌单元的容置腔内的待脱嵌液体进行搅拌，并控制供电模块以恒压模式为目标脱嵌单元进行供电。其中，预设安全工作电压为目标脱嵌单元的安全工作电压。
采用该方法，当目标脱嵌单元的工作电压大于或等于预设安全工作电压时，控制目标向心搅拌器停止对目标脱嵌单元的容置腔内的待脱嵌液体进行搅拌，并控制供电模块以恒压模式为目标脱嵌单元进行供电，可以预防由于发生意外事件而导致目标脱嵌单元的工作电压超过其预设安全工作电压，避免了目标脱嵌单元的工作电压超过其预设安全电压的风险。意外事件为：能造成搅拌也无法降低目标脱嵌单元的工作电压的事件。
以预设安全工作电压为3V为例进行说明：预设电压阈值可以设置为略小于预设安全工作电压的2.8V，当目标脱嵌单元的工作电压大于2.8V时，开始对目标脱嵌单元的容置腔内的待脱嵌液体进行搅拌，并实时采集目标脱嵌单元的工作电压，若目标脱嵌单元的工作电压大于或等于3V，控制单元控制目标向心搅拌器停止对目标脱嵌单元的容置腔内的待脱嵌液体进行搅拌，并控制供电模块以恒压模式为目标脱嵌单元进行供电。
在一些实施例中，当控制单元从多个脱嵌单元中确定工作电压大于或等于对应的预设电压阈值的脱嵌单元为目标脱嵌单元时，控制单元还可以控制电化学脱嵌槽系统中目标脱嵌单元对应的报警模块进行报警，从而提醒工作人员注意目标脱嵌单元的工作电压存在超过预设安全电压的风险，以便当发生意外情况时，工作人员可以及时处理；当控制单元监测到目标脱嵌单元的工作电压小于对应的预设电压阈值时，控制单元可以控制电化学脱嵌槽系统中目标脱嵌单元对应的报警模块停止报警。

在可能的实现实例中，搅拌控制模块604，还用于若监测到所述目标脱嵌单元的工作电压小于对应的预设电压阈值，则控制所述目标向心搅拌器停止对所述目标脱嵌单元的容置腔内的待脱嵌液体进行搅拌；若所述目标脱嵌单元在预设历史时间段内工作电压大于或等于对应预设电压阈值的次数小于或等于预设次数阈值，则控制所述目标脱嵌单元中设置的目标向心搅拌器对所述目标脱嵌单元的容置腔内的待脱嵌液体进行搅拌；若所述目标脱嵌单元在所述预设历史时间段内工作电压大于或等于对应预设电压阈值的次数大于所述预设次数阈值，则控制所述目标向心搅拌器停止对所述目标脱嵌单元的容置腔内的待脱嵌液体进行搅拌，并控制所述供电模块以恒压模式为所述目标脱嵌单元进行供电；若目标脱嵌单元中设置的目标向心搅拌器的工作时长大于或等于预设时长，则控制目标向心搅拌器停止对目标脱嵌单元的容置腔内的待脱嵌液体进行搅拌，并控制供电模块以恒压模式为目标脱嵌单元进行供电；若目标脱嵌单元的工作电压大于或等于预设安全工作电压，则控制目标向心搅拌器停止对目标脱嵌单元的容置腔内的待脱嵌液体进行搅拌，并控制供电模块以恒压模式为目标脱嵌单元进行供电。
