The invention relates to the technical field of ships, and discloses an automatic liquid supplementing device and method for a marine diesel engine aftertreatment system, and the automatic liquid supplementing device comprises a daily cabinet, a liquid storage cabinet and a connecting pipeline. The daily cabinet is connected with a marine diesel engine post-processing system, the liquid storage cabinet is used for storing urea solution, and the installation height of the liquid storage cabinet is larger than that of the daily cabinet. One end of the connecting pipeline is connected with the liquid storage cabinet, and the other end selectively communicates with the daily cabinet. When the liquid level in the daily cabinet is lower than a first liquid level threshold value, the liquid storage cabinet can be communicated with the daily cabinet through the connecting pipeline. According to the automatic liquid supplementing device, driving mechanisms such as a urea pump do not need to be additionally arranged, automatic liquid supplementing for the marine diesel engine post-processing system is achieved only by reasonably arranging the positions of the liquid storage cabinet and the daily cabinet, the structural design is simple, the installation construction steps of the automatic liquid supplementing device on a ship can be simplified, the construction cost and construction difficulty are reduced, and the working efficiency is improved. And faults caused by frequent start and stop of the machine are avoided by means of automatic liquid supplementing by gravity, and the working reliability is high.

    本发明涉及船舶技术领域,公开一种船舶柴油机后处理系统的自动补液装置及方法,自动补液装置包括日用柜、储液柜和连接管路。日用柜与船舶柴油机后处理系统连接,储液柜用于储存尿素溶液,其安装高度高于日用柜的安装高度。连接管路的一端连接储液柜,另一端选择性地导通日用柜。日用柜内的液位低于第一液位阈值时,储液柜能够通过连接管路与日用柜导通。该自动补液装置无需额外设置尿素泵等驱动机构,仅通过合理布局储液柜和日用柜的位置便实现了为船舶柴油机后处理系统自动补液,结构设计简单,能简化自动补液装置在船舶上的安装施工步骤,降低施工成本和施工难度,依靠重力自动补液的方式不存在因机器频繁启停导致的故障,工作可靠性高。
