Fire extinguishing device and method

Abstract

The invention discloses a fire extinguishing device and a fire extinguishing method. The fire extinguishing device comprises a gas storage device, a liquid storage device and a nozzle, wherein a first gas outlet and a second gas outlet are formed in the gas storage device; the liquid storage device is provided with a first gas inlet and a liquid outlet; the nozzle is provided with an atomization channel, a second gas inlet and a liquid inlet; a spraying opening is formed in one end of the atomization channel; the first gas inlet and the liquid inlet are communicated with the atomization channel; the first gas outlet is communicated with the first gas inlet; the second gas outlet is communicated with the second gas outlet; and the liquid outlet is communicated with the liquid inlet. High-pressure gas is used as a power source, and a pump set and a system for supplying power to the pump set are not adopted, so that the device has no fire hazard; the maintenance frequency is low and the service life is long; the water use amount of the system is less and the cleaning time is relatively short after the releasing; and the damages to objects by water stains are small and the time for recovering operation is short.

Description

technical field [0001] The invention belongs to the field of fire protection, and in particular relates to a fire extinguishing device and method. Background technique [0002] At present, according to the frequent burning incidents of public transport vehicles in recent years, it is found that the main cause of public transport vehicle fires is arson. For this type of fire, direct watering is very harmful, and spray fire is usually used. However, the existing spray fire extinguishing device applies high pressure to the water to atomize it, and the vehicle needs to be equipped with a heavy high-voltage system, including a battery, a high-pressure water pump, and the like. The load is wasted, and the maintenance of the high-voltage system is difficult, and it has potential safety hazards. For example, high-pressure water pumps are easily corroded and damaged. Once damaged, the fire extinguishing system will be unusable, which is very dangerous. Pumps and other energy-consum...

Problems solved by technology

However, the existing spray fire extinguishing device applies high pressure to the water to atomize it, and the vehicle needs to be equipped with a heavy high-voltage system, including batteries, high-pressure water pumps, etc.

Waste of load, and the maintenance of the high-voltage system is difficult, and it has potential safety hazards

For example, high-pressure water pumps are easily corroded and damaged. Once damaged, the fire extinguishing system will be unusable, which is very dangerous; pumps and other energy-consuming equipment need to be equipped with special power cables for their use. Such power cables themselves have the potential for short circuit and fire hazards.
