A floating plate for releasing floating fire extinguishing bombs in a tank

Abstract

The invention discloses a floating plate for releasing floating fire extinguishing bombs in a tank. The floating plate is arranged in the tank body of an oil tank. The floating fire extinguishing bombs are hung on the hanger by hooks, and the hooks are made of low-melting point materials. The fire extinguishing bombs Including the projectile and the fire extinguishing agent in the projectile, the interior of the projectile is hollow, and the fire extinguishing agent is filled in the projectile. It is characterized in that: a partition plate is arranged in the projectile, and the partition plate divides the internal cavity of the projectile into a high-pressure air chamber and the fire extinguishing agent chamber, a pressure relief hole connecting the fire extinguishing agent chamber and the high-pressure air chamber is arranged on the partition plate, the pressure relief hole is sealed by a low melting point alloy material, and a fire extinguishing agent nozzle is arranged in the body, and one end of the fire extinguishing agent nozzle extends into the fire extinguishing agent chamber, and the other end penetrates the side wall of the projectile to communicate with the outside world. Compared with the prior art, the present invention has the following advantages: large coverage, convenient dispensing, high fire extinguishing efficiency, safety and reliability, easy recycling and use, and no secondary pollution.

Description

technical field [0001] The field of the invention relates to the technical field of fire extinguishing, to be precise, it is a new type of fire extinguishing bomb that floats on the oil surface and sprays fire extinguishing agent to isolate the air on the oil surface to achieve the fire extinguishing effect. Background technique [0002] In recent years, fire accidents in my country's petrochemical, chemical and other process industries are on the rise. If a fire occurs in some large-scale hazardous chemical storage facilities, such as large oil storage tanks, very serious tank deformation, inclination, leakage or even explosion may occur, often causing a large number of casualties, major economic losses or serious environmental damage. Pollution has unimaginable consequences. However, for major oil storage tank fires, the general fire extinguishing methods often have little effect. General fire extinguishing bombs are thrown into the fire based on the principle of explosi...

If a fire occurs in some large-scale hazardous chemical storage facilities, such as large oil storage tanks, very serious tank deformation, inclination, leakage or even explosion may occur, often causing a large number of casualties, major economic losses or serious environmental damage. Pollution, with disastrous consequences

However, for major oil storage tank fires, common fire extinguishing methods often have little effect

General fire extinguishing bombs are thrown into the fire based on the principle of explosion for fire extinguishing, but this method has obvious disadvantages. First, it is low in safety. During the transportation and installation of the fire extinguishing bomb, it is easy to accidentally explode due to vibration caused by improper operation. Cause safety accidents; secondly, the fire extinguishing coverage area is small, when the fire extinguishing bomb explodes when it touches the ground, the range that the fire extinguishing agent in the fire extinguishing bomb can cover is limited, and the maximum coverage area cannot be reached, which affects the fire extinguishing efficiency; and then after the fire extinguishing bomb explodes , the injection direction of the fire extinguishing agent is uncontrollable, because the material of the projectile body makes the fragments of the projectile scattered after the explosion affect the spraying direction and distance of the fire extinguishing agent, and affects the fire extinguishing effect; finally, the materials for making the fire extinguishing bomb are all made of plastic, which cannot Degradable or difficult to degrade, causing secondary pollution to the environment
