A kind of urban turbojet fire truck

Abstract

The invention provides an urban turbojet fire vehicle. The fire vehicle comprises a vehicle chassis. An ultrafine dry powder tank is arranged on the vehicle chassis. The ultrafine dry powder tank is connected with a nitrogen cylinder pressure vessel. The nitrogen cylinder pressure vessel is connected with a water pump system. The water pump system is connected with a liquid tank assembly. The liquid tank assembly is connected with a turbojet engine jet assembly. A jet device for fire extinguishing comprises a jet device. The jet device is connected with a central revolved body through a connection pipe. The urban turbojet fire vehicle has large jet power, can jet out a mass flow of 'tail gas-water spray-ultrafine dry powder' three-phase jet flow fire extinguishing agents in a short time, and has excellent capabilities of controlling fire behavior, extinguishing big fires and cooling fire scenes by aeration from the three-dimensional space. The urban turbojet fire vehicle plays an important role in extinguishing high-rise building fire disasters, unattended dangerous chemical warehouse fire disasters, underground garage fire disasters, cable trench fire disasters, tunnel fire disasters, historic building fire disasters and steamship cabin fire disasters.

Description

technical field [0001] The invention belongs to the field of fire protection, and specifically relates to a composite fire truck which uses a turbojet engine as the injection power and can simultaneously inject multiple fire extinguishing agents. Background technique [0002] The fire truck is the main fire fighting equipment with high mobility currently used to extinguish various fires. The following shortcomings were exposed in the fire fighting battle: first, only a single fire extinguishing agent can be sprayed, and the fire extinguishing strengths of fire extinguishing agents with different properties cannot be used. At the same time, more than two kinds of fire extinguishing agents are combined in compound injection to quickly extinguish flammable material fires; The reason is that the sprayed fire extinguishing agent lacks dispersibility. In order to maintain the existence rate of the fire extinguishing agent in the three-dimensional space of the fire, the fire exting...

Problems solved by technology

The following shortcomings were exposed in the fire fighting battle: first, only a single fire extinguishing agent can be sprayed, and the fire extinguishing strengths of fire extinguishing agents with different properties cannot be used. At the same time, more than two kinds of fire extinguishing agents are combined in compound injection to quickly extinguish flammable material fires; The reason is that the sprayed fire extinguishing agent lacks dispersibility. In order to maintain the existence rate of the fire extinguishing agent in the three-dimensional space of the fire, the fire extinguishing agent has to be sprayed continuously, resulting in serious water loss and chemical pollution to the environment; the third is to extinguish airtight When there is a fire in the space, a fire extinguishing channel must be opened to find the fire source and extinguish it, thus causing fresh air to enter the room, increasing the difficulty of extinguishing the fire and prolonging the time for extinguishing the fire

As we all know, water jet has an excellent ability to impact flames and cool down, but its ability to prevent oil fires from re-igniting is far inferior to foam fire extinguishing agents; foam fire extinguishing agents have excellent ability to prevent oil fires from re-igniting, but their fire extinguishing speed Far inferior to ultra-fine dry powder fire extinguishing agent; ultra-fine dry powder fire extinguishing agent has extremely high fire extinguishing efficiency, but its ability to penetrate flames and prevent oil fire from re-igniting is weak when extinguishing outdoor fires
