Compression nitrogen gas foam extinguishing system

The utility model discloses a compression nitrogen gas foam extinguishing system. The utility model discloses an including foam truck and nitrogen gas car, the foam truck is the same basically with foam truck among the prior art, the utility model discloses a be equipped with compression nitrogen system on the nitrogen gas car, nitrogen system includes nitrogen gas generating device and gas transmission pipeline, nitrogen gas generating device gives vent to anger to hold and connects the water foam liquid mixing duct on the foam truck through the gas transmission pipeline, constitutes compression nitrogen gas foam liquid pipeline. The technique effect has been stopped the oxygen in the air combustion -supporting and improved the isolated effect of foam, obtains the reinforcing to the suppression ability of conflagration. Regard nitrogen gas generating device as a separate unit for nitrogen gas can be supplied continually, thereby has improved whole fire extinguishing systems's fighting ability, is particularl
