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.

Description

technical field [0001] The present application relates to the technical field of lithium-ion battery energy storage, in particular to a fire extinguishing system for suppressing fire and explosion in energy storage power stations. Background technique [0002] Energy storage power station technology is a sustainable and clean energy utilization technology. Energy storage not only ensures the stability and reliability of the grid system, but also an effective way to solve dynamic power quality problems such as voltage pulses, inrush currents, voltage dips, and instantaneous power interruptions. In recent years, energy storage has shown a good trend of diversified development, and energy storage technology has basically established the basis for industrialization in general. Energy storage is an emerging strategic industry. At present, the fire safety technology of energy storage power stations is one of the key bottlenecks hindering the large-scale development of energy stor...

Problems solved by technology

This technology uses the combination of heptafluoropropane and fine water mist. However, there is still a lot of controversy about the use of fine water mist to extinguish electrical fires. Heptafluoropropane has the disadvantages of high greenhouse effect potential and poor fire extinguishing effect. In addition, the heat generated by the battery When out of control, the surface is in the low-temperature stage, and the water cannot be vaporized quickly, so it cannot cool down quickly

[0004] From the above, it can be seen that the fire protection system of the current energy storage power station has poor explosion suppression performance.
