Problems solved by technology

However, the composition of the system is relatively complicated, and the cost is relatively high, so it is not suitable for use in super large spaces and places where people often work.
[0022] In a word, the above-mentioned fire extinguishing system has certain defects in carrying out fire extinguishing in a relatively closed space.

Abstract

The submerged fire extinguishing nitrogen system for closed space includes a nitrogen supplier, a flow meter, a solenoid valve, a fire alarming controller, a pipeline with branches, nitrogen nozzles and a fire detector connected together. The present invention has no environmental pollution, no damage of generating secondary fire, simple system structure, low cost, stable running and other advantages.

Description

technical field [0001] The invention relates to a fire extinguishing device, in particular to a fully submerged nitrogen fire extinguishing system in a relatively closed space. Background technique [0002] At present, fires in various relatively closed spaces in enterprises have become a problem that cannot be ignored in the production process. Taking the fire in the tunnel cable in the iron and steel metallurgical enterprise as an example, as a relatively closed space, the main reasons for the fire in the tunnel cable are as follows: [0003] 1) A fire that occurs under the action of external heat. At the fire scene, the high temperature of the fire field acts on the wire and cable, and its insulating layer will embrittle, carbonize, or even burn in a very short period of time, thus losing its insulating ability, causing a short circuit, and causing secondary electrical fires or explosions. Under the action of external heat, the insulating material polyvinyl chloride beg...
