Fire extinguishing system for inhibiting fire explosion of energy storage power station

Abstract

The invention relates to a fire extinguishing system for inhibiting fire explosion of an energy storage power station. The fire extinguishing system comprises a refrigerant cooling spray heads, refrigerant system pipe networks, refrigerant storage tanks filled with a refrigerant, gas fire extinguishing system spray heads, gas fire extinguishing system pipe networks and gas storage tanks filled with a gas fire extinguishing agent, wherein each refrigerant cooling spray head is arranged above each battery module in the container energy storage power station; each refrigerant cooling spray nozzleis connected to the refrigerant storage tank through the refrigerant system pipe network to form a fixed refrigerant pipe network system; the gas fire extinguishing system spray heads are arranged inthe container energy storage power station; each gas fire extinguishing system spray head is connected to the gas storage tank through the gas fire extinguishing system pipe network to form a fixed gas fire extinguishing agent pipe network system; a refrigerant is released through the fixed refrigerant pipe network systems to perform cooling and explosion suppression on the battery; and the fixedgas fire extinguishing agent pipe network systems release a gas extinguishing agent to extinguish flame, so that efficient fire extinguishing is achieved, and after-combustion and explosion are effectively inhibited.
