Embodiment Construction

[0043] Hereinafter, the embodiments of the present invention will be described in detail according to the embodiments with reference to the accompanying drawings.

[0044] figure 1 Examples of the invention are shown. On the closed space 1 that needs to be protected, an air circulation device 2 is installed to make the oxygen concentration in the space uniform, and the nitrogen-enriched air discharged from the space that does not reach the predetermined concentration is returned to the nitrogen-enrichment device for recycling. , the fire detection device 4, the oxygen concentration sensor 5 for measuring the oxygen concentration in the space, the control part 6 for controlling the nitrogen enrichment device, the nitrogen storage switch valve and the nitrogen release solenoid valve, the nitrogen storage switch valve 7, the nitrogen enriched air generator 8, the The recycled nitrogen-enriched air is mixed with fresh air and introduced into the mixer 9 of the nitrogen-enriched d...

Abstract

An equipment for preventing and extinguishing the fire accident in an enclosed space is composed of a nitrogen-enriching unit which can use a gas separating membrane to lower the oxygen concentration and release nitrogen gas to maintain a predefined nitrogen concentration, a unit for circulating the nitrogen-enriched air, an air stirrer, an oxygen sensor, a pressure balancer, an alarm for fire accident, an oxygen concentration controller, and an oxygen-enriched air deluting unit.

Description

Technical field: [0001] The invention belongs to the field of fire protection, and in particular relates to a fire prevention and fire extinguishing equipment used in a closed space. Background technique: [0002] Information communication equipment, high-value equipment, valuable data and cultural relics are installed and stored in modern buildings. It goes without saying that the fire prevention and extinguishing of these enclosed spaces is very important, but the existing methods are not perfect. [0003] The main fire extinguishing methods used in existing closed spaces are water (such as sprinkler fire extinguishing equipment) and use of gas (that is, fire extinguishing by releasing fire extinguishing gas). Extinguish fire with water, water damage is possible. In some cases, the damage caused by using water to extinguish the fire is greater than that of the fire. Therefore, for cultural relics, electronic communication equipment and important databases, etc., it is n...
