Bursting discs for energy storage industry, as a non-re-closed overpressure relief device, has the advantages of fast reaction speed, wide adaptability to media, and compact structure. It has irreplaceable safety protection in many subdivided fields such as electrochemical energy storage, mechanical energy storage, and thermal energy storage. Through precise control of the release pressure, the rupture disc can quickly relieve pressure in the event of emergency situations such as overpressure and thermal runaway in the system, and effectively prevent vicious accidents such as explosions and leaks. It is an important part of the safety system of energy storage equipment.
Electrochemical energy storage is currently the fastest growing field of energy storage. At the battery module level, when the gas inside the single battery or module is violently released due to overcharging, short circuit, or thermal runaway, bursting discs for energy storage industry can rupture within milliseconds, quickly release the internal high-pressure gas, and prevent the module housing from exploding due to overpressure. At the level of battery clusters and energy storage containers, equipment such as combiner boxes and battery cabinets also need to be installed with rupture discs for overpressure protection. When the heat of a single module spreads out of control to the cluster, a large number of high-temperature and high-pressure gases gather. Bursting discs for energy storage industry can open the discharge channel according to the preset pressure value to direct dangerous gases to a safe area for discharge, while cooperating with the fire extinguishing system to suppress the spread of the fire.
Mechanical energy storage systems have strict requirements for pressure control, and bursting discs for energy storage industry is an important device to ensure the safety of pressure systems. In a compressed air energy storage system, equipment such as gas storage tanks, pipelines, and compressors are in a state of high pressure for a long time. When the pressure of the system exceeds the safety limit due to pressure control failure or equipment failure, the rupture disc can instantly rupture and relieve pressure, preventing the gas storage tank from physically exploding. In the flywheel energy storage system, the high-speed operation of rotating parts may cause abnormal air pressure inside the equipment. The rupture disc is installed on the pressure relief channel of the flywheel housing. When the pressure in the housing is abnormally increased due to friction, heat generation or sealing failure, bursting discs for energy storage industry can quickly release the pressure to prevent the housing from being deformed or bursting due to excessive pressure.
The operating environment of the thermal energy storage system has the characteristics of high temperature and high pressure. Bursting discs for energy storage industry has the role of overpressure protection and thermal runaway prevention. In the molten salt energy storage system, the temperature of the molten salt medium in the heat storage tank and the heat transfer pipeline can reach more than 500℃. When the system has a heat exchange failure that causes the local temperature to rise sharply and the pressure is abnormal, the rupture disc can open the discharge channel in time to prevent high-temperature molten salt leakage from causing fire or equipment damage. In phase change energy storage equipment, the pressure fluctuation of the phase change material may be caused by volume changes during the endothermic and exothermic processes. The rupture disc can balance the internal pressure of the equipment and prevent the shell from breaking due to the sudden increase in pressure.
