Based on the principle of "early detection and early disposal", advance detection and early warning (extremely early detection) should be carried out for Lithium Battery thermal runaway in the Storage tank at the initial stage, and accurate multiple point spraying should be used to suppress and deal with the Fire in the tank, so as to extinguish the Fire at the initial stage.
Mainly to detect and alarm system: Instead of the traditional general layout of the whole space smoke sensor, temperature sensor as a fire detection method, the use of lithium battery special compound sensor, in each battery cluster layout of 4 compound sensors, at the same time to detect the temperature of the battery box, carbon monoxide (CO), hydrogen (H2), electrolyte leakage gas (VOC), smoke and other parameters.
The electrochemical storage tank fire extinguishing system is mainly adopted: perfluorohexanone is used in the early stage of non-destructive and precise multiple injection fire extinguishing, and water mist is used in the later stage of continuous cooling in the battery cabin.
Through the comprehensive algorithm for judgment, the signal is transmitted to the host and then transmitted to each platform. The detection and alarm system can detect the signal released by a single battery module in the early stage of fire very early, which can save more time to process information and suppress the fire in the early stage.
And each battery cluster is equipped with a solenoid valve for a protection unit; The water mist nozzle is installed on the top of the battery compartment, and each battery compartment is a protective unit of the water mist fire extinguishing system. The water mist fire extinguishing system and the perfluorohexanone fire extinguishing system are contained in the fire extinguishing device of the electrochemical energy storage tank. The two systems share the same pipe network. When the lithium battery thermal loss occurs, perfluorohexanone is sprayed first, and the water mist can be manually sprayed remotely or locally as required.
