Fire extinguishing system for vehicle

Abstract

The invention provides a fire extinguishing system for a vehicle. The system comprises atomization spray heads, a conveying pipeline and a fire extinguishing agent storage tank; the fire extinguishing agent storage tank comprises a storage tank body and a starting valve; one end of the conveying pipeline is connected with an outlet of the starting valve, and the other end of the conveying pipeline is connected with the atomization spray heads; driving gas and fire extinguishing agents are stored in the storage tank body; and the starting valve is provided with a low-pressure warning device and / or a high pressure release device. According to the fire extinguishing system for the vehicle, the effects that the fire extinguishing system can be maintained more timely when the pressure is too low and works within a safety pressure range are ensured; perfluorinated ethyl isopropyl ketone serves as a fire extinguishing medium, a large amount of heat in a combustion zone can be quickly decreased, meanwhile, the concentration of oxygen on the surfaces of comburents can be reduced, quick fire extinguishing is achieved, and reburning is prevented.

Description

technical field [0001] The present invention relates to the technical field of fire protection, and more specifically, to a vehicle fire extinguishing system. Background technique [0002] With the continuous acceleration of the urbanization process in our country, the urban population has increased rapidly, and the urban traffic has become increasingly congested. After years of hard work, most cities in our country have built a convenient and fast bus system with wide coverage. However, the current bus system in most cities in my country only meets the basic problem of whether people have cars or not, and has not been able to provide a better ride environment and formulate and implement a sound safety management system, leaving certain hidden dangers. In recent years, public transport, especially urban bus fire accidents have occurred frequently, exposing serious hidden dangers in the current public transport management system and fire safety measures in some areas of our c...

Problems solved by technology

However, the fire extinguishing system is manually controlled by the driver, and the driver may miss the best time to extinguish the fire while driving the vehicle; at the same time, because the water is sprayed through the water pump and the sprinkler head, the fire extinguishing speed and efficiency are very low, and the requirements for rapid fire extinguishing cannot be met.

[0004] In addition, the dry powder fire extinguishing agent equipped with large vehicles may enter the respiratory tract of escaped personnel after spraying, and block people's sight, thus causing further harm.

The green and environmentally friendly water mist fire extinguishing system has the disadvantage of high water quality requirements, because if the water quality is poor, it will cause nozzle blockage, which will not only affect the performance of the nozzle, but also cause damage to the nozzle

In addition, compared with some gas fire extinguishing systems, the water mist system takes a longer time to extinguish the fire

And it is not suitable for some objects that will react strongly with water

At the same time, the automatic fire extinguishing device currently equipped on the car may have failed after several years of installation, but the driver does not know it, and eventually loses the opportunity to extinguish the fire
