The vortex fire truck is a kind of extraordinarily powerful fire-fighting equipment, which has its unique advantages in extinguishing oil and gas fires and forced ventilation cooling. At present, many countries in Asia have developed and produced turbojet engines for sale in the international market. Due to different design ideas, the structural design of the vortex fire fighting device has its own characteristics. Extinguishing: When a vortex fire truck extinguishes a fire at a fire site, the vortex extinguishing system fires the fire extinguishing agent with a large flow rate, a high speed, and a high intensity in a horizontal direction. The injection distance is long, and the ability to penetrate the center of the flame is strong, and the fire extinguishing is greatly improved. Efficiency reduces waterlogging hazards and environmental pollution and can achieve short-term rapid extinguishing. Cooling: The cooling efficiency of vortex fire engines is mainly reflected in the large diameter of the water guns and the high flow rate. After the fire extinguishing agent is sprayed, it is flared. After field test, the maximum diffusion arc is more than 50 meters. It can provide all-directional and package-type cooling to the parts to be cooled, especially for the protection of oil tanks caused by petrochemical fires. obvious. Ventilation and Exhaust: The vortex firefighting vehicle applies positive pressure ventilation to the fire, eliminates smoke, enhances visibility of the fire, reduces the possibility of "flashing fire," and facilitates the organization of firefighters' offensive and covert evacuation. After extinguishing the fire on fire sites and leaking sites of large-scale petrochemical enterprises, positive pressure ventilation can be implemented, which can quickly cool down, dilute poisonous and harmful gases, protect firefighters and rescue victims. Dividing the fire: It can make full use of the huge kinetic energy of the vortex fire truck and inject it from the fire side to prevent the fire from crossing the blasting area, effectively preventing the spread, protecting the adjacent buildings and avoiding the fire from causing greater losses.
