DETAILED DESCRIPTION OF EMBODIMENT (S) OF INVENTION

The nitrogen fire extinguishing mode is widely applied to the fire fighting industry. In order to deal with different kinds of fire, nitrogen and solid or foam are mixed with each other to extinguish fire, and the nitrogen and solid or foam are gradually popularized. However, the method of producing high-pressure nitrogen by using a nitrogen cylinder, a nitrogen storage tank or liquid nitrogen has the disadvantages of difficult supply and short duration, so that a nitrogen production device is required to produce and supply nitrogen on site to provide fire extinguishing medium for a fire truck.

As shown in fig. 8 and 9, the nitrogen preparation apparatus 120 'of the fire fighting vehicle 100' in the related art prepares nitrogen through a normal temperature air separation apparatus, mixes high pressure nitrogen with foam to generate a nitrogen foam mixed liquid, provides a fire extinguishing medium for the fire fighting vehicle 100 ', has a slow preparation speed and a small number of fire extinguishing types, and thus the fire fighting vehicle 100' is limited by the fire environment. Meanwhile, in the related art, the nitrogen preparation device 120 'is often driven by a hydraulic motor, the system is complex, and the cost of the fire fighting truck 100' is increased. And as shown in fig. 10, the nitrogen preparation device 120 'occupies a large space, reducing the space utilization of the fire fighting truck 100'.

In the related art, the nitrogen preparation apparatus 120 'includes an air compression apparatus 160', the air compressed by the air compression apparatus 160 'enters an air processing system 162', the air cleaned by the air processing system 162 'enters an ambient air nitrogen production apparatus 164', and the air leaving the ambient air nitrogen production apparatus 164 'enters a nitrogen pressurization apparatus 166' to separate oxygen and nitrogen. The nitrogen then enters the foam generating device 168 'to mix with the foam concentrate, foam is generated and forced against the fire suppression site 170'. The foam concentrate in foam generating device 168 'is from foamer tank 172'. The foam concentrate from the foaming agent tank 172 'is metered by the metering pump 174', and the fire-fighting water from the fire pump 176 'is also pressurized at the fire-fighting site 170'. As shown in fig. 10, the foam generator 140 ' of the related art fire fighting vehicle 100 ' generally adopts a T-shaped structure, so that foam and nitrogen gas flow paths are in opposite impact, thereby causing insufficient mixing of the foam and the nitrogen gas, and affecting the fire extinguishing performance of the fire fighting vehicle 100 '. As shown in fig. 11, the telescopic boom 150 ' of the fire fighting truck 100 ' in the related art has a small horizontal working range and low flexibility, which affects the fire fighting truck 100 ' to carry out fire fighting operations.
