Annular fine water mist fire extinguishing cover system

Abstract

The invention discloses an annular fine water mist fire extinguishing cover system. The annular fine water mist fire extinguishing cover system comprises a fine water mist spraying mechanism; the fine water mist spraying mechanism includes a high-pressure water distributor and more than two annular water pipes; each annular water pipe is communicated with the high-pressure water distributor through more than high-pressure water distribution pipes; and each annular water pipe is respectively provided with more than two fine water mist nozzles. The annular fine water mist fire extinguishing cover system is fast in fire extinguishing speed and high in fire extinguishing efficiency, and cannot generate secondary pollution to surrounding environments. The annular fine water mist fire extinguishing cover system can be used for cooling exposed combustible gas or liquid pipes after fire extinguishing, overcomes the defects of low fire extinguishing efficiency and bad fire extinguishing agent waste in a traditional spraying dry powder fire extinguishing agent, and satisfies the purposes and the technical requirements of effectively extinguishing the oil tank fire.

Description

technical field [0001] The invention relates to the field of fire fighting equipment, in particular to an annular fine water mist fire extinguishing cover system. Background technique [0002] In recent years, with the rapid development of underground oil and gas pipelines in my country, the underground pipeline network is intricate, and factors such as earth excavation or ground subsidence often cause damage to pipelines and frequent major fire accidents. [0003] According to the technical requirements, the gas pipeline network fire must be extinguished first, then the valves should be closed, and then excavated for maintenance. At present, the traditional fire extinguishing method is to spray dry powder fire extinguishing agent in the area near the burning point to extinguish the fire. Once there is wind, part of the dry powder fire extinguishing agent will be blown away by the wind, the fire extinguishing speed is slow, the waste of fire extinguishing agent is serious, a...

AI Technical Summary

Problems solved by technology

At present, the traditional fire extinguishing method is to spray dry powder fire extinguishing agent in the area near the burning point to extinguish the fire. Once there is wind, part of the dry powder fire extinguishing agent will be blown away by the wind, the fire extinguishing speed is slow, the waste of fire extinguishing agent is serious, and the dry powder fire extinguishing agent is expensive. The amount of fire extinguishing required for fire extinguishing is large, the economic loss is large, and the dry powder fire extinguishing agent also produces secondary pollution after fire extinguishing

[0004] In addition, if the oil pipeline fire is extinguished, the dry powder fire extinguishing agent will also cause serious pollution of the leaked oil, which cannot be reused, and the economic loss is large; for normal maintenance
