Fire extinguishing system and method

Abstract

The invention provides a fire extinguishing system. The fire extinguishing system comprises a fire detection system used for detecting whether fire occurs in equipment, a spraying system used for spraying to extinguish the fire when the fire occurs, and a carbon dioxide system used for injecting carbon dioxide into the equipment to extinguish the fire after spraying of the spraying system. The fire extinguishing system further comprises a controlling system which is used for controlling the equipment to stop working and stating the spraying system after a first period when receiving fire extinguishing starting commands, a counting system which is used for collecting, counting, analyzing and storing data for subsequent use, external fire extinguishing equipment which is used for being started to conduct fire extinguishing from the outside when the spraying system is started. The invention further provides a controlling method of the fire extinguishing system. The internal and external fire of the equipment can be sensed, and therefore the fire extinguishing commands can be issued. Simultaneous fire extinguishing can be conducted based on the interior and exterior of the equipment, and further spread of the fire can be prevented.

Description

technical field [0001] The invention relates to the field of equipment fire extinguishing, in particular to a fire extinguishing system and method, especially a fire extinguishing system and method inside and outside the equipment. Background technique [0002] Fires in cold-rolling factories are the most common among steelmaking fires in the world. When a fire occurs, the factory is burned down, production is interrupted, etc., causing great economic losses. As the core equipment of the cold rolling factory, the equipment is one of the important reasons for the fire in the cold rolling factory. [0003] Three conditions must be met for a fire accident to occur in a cold rolling mill during high-speed operation: (1) Combustible materials, such as rolling oil, cotton yarn, rubber hose, etc.; (2) Combustible materials, that is, oxygen in the air; Such as friction, electric spark, static electricity, open flame, etc. The oil vapor produced by the high-speed cold rolling mill ...

AI Technical Summary

Problems solved by technology

When a fire breaks out inside the equipment, the fire flows back through the equipment table, causing the fire to spread and making it difficult for fire trucks to enter the factory, making it difficult to extinguish the fire
