Abstract

This invention belongs to the field of lithium battery fire protection technology, specifically relating to a combined fire extinguishing system and an electrochemical energy storage system. A gaseous fire extinguishing agent storage tank is connected to a pipe network via pipelines, and a main switch valve is installed on the pipeline connecting the gaseous fire extinguishing agent storage tank to the pipe network. One end of a water pump is connected to a water source, and the other end is connected to the pipe network via a corresponding pipeline, with a second main switch valve installed on the pipeline connecting the water pump to the pipe network. The pipe network includes several longitudinal branch pipes, the length of which is along the height of the space containing the pipe network. Several nozzles are installed on each of the longitudinal branch pipes, spaced apart along the length of their respective longitudinal branch pipes. This system offers high flexibility, allowing for prolonged continuous cooling and suppression, improving the efficiency and reliability of open flame extinguishing and subsequent suppression, preventing reignition and thermal runaway, and reducing losses and safety hazards caused by reignition and thermal runaway.
