6 FAQs about [Stored energy gas fire extinguishing device]
What is the mechanism of fire-extinguishing agent?
The mechanism of fire-extinguishing agent is mainly divided into isolation, smothering, cooling and chemical suppression. However, the fire triangle of battery is difficult to destroy, as the three elements of fire triangle can be provided by the battery itself. In addition, LIB fire is a complex fire with the characteristics discussed above.
What is a fire extinguishing device?
Fire extinguishing device refers to the equipment that sprays the internal fire extinguishing agent under the action of the internal pressure of the equipment to achieve a good fire extinguishing effect.
Which extinguishing agent is used to suppress libs fire?
Currently, the common fire-extinguishing agents applied to suppress LIBs fire can be divided into gaseous extinguishing agent (CO 2, HFC-227ea, C 6 F 12 O etc.), liquid extinguishing agent (water-based fire-extinguishing agent, liquid nitrogen etc.) and solid extinguish agent (dry powders, aerosol fire-extinguishing agent etc.).
Are gas based fire extinguishing agents good?
Gas extinguishing agents present excellent fire-extinguishing performance, but the cooling effect is insufficient, which leads to the serious problem of re-ignition. While water-based fire-extinguishing agents demonstrate excellent cooling capability, but the extinguishing efficiency is insufficient.
Which fire extinguishing agent is best in enclosed space?
Gaseous fire-extinguishing agents show more excellent extinguishing capacity in enclosed space . Among gaseous fire-extinguishing agents, the extinguishing capacity of C 6 F 12 O and liquid nitrogen show best, followed by HFC-227ea .
What makes a good fire extinguishing system?
An ideal fire extinguishing system should have excellent fire extinguishing and cooling effects, which can quickly extinguish open flames and reduce battery system temperature. Specifically, extinguishing systems whose aim it to prevent module-to-module, and beyond, propagation.
