Embodiment 1

[0022] Three-phase composite foam liquid, including gas-liquid phase foam liquid and solid phase medium mixed with each other, the solid phase medium is particles with pores inside; The surface area of ​​the phase medium particles; the specific gravity of the solid phase medium particles is less than that of the oil. It can float on the oil surface; the solid phase medium particles are zeolite particles. The ratio of the gas-liquid phase foam liquid to the solid phase medium particles is 16:1-20:1. It is applied to the initial fire where the oil surface burning time is ≤10min and the oil surface temperature is ≤100°C. This kind of three-phase composite foam The liquid has good fluidity and can quickly cover the oil surface. The fire extinguishing device of the three-phase composite foam liquid comprises a gas-liquid phase foam liquid storage 2 and a solid phase medium storage 3 connected with the foam liquid and solid medium mixer 4, and the gas-liquid phase foam liquid stora...

Embodiment 2

[0024] The three-phase compound foam liquid and its application, its fire extinguishing device and its use method are the same as in Example 1, the difference is that the ratio of gas-liquid phase foam liquid and solid phase medium particles is 4:1-8:1 and applied to the oil surface Burning time ≥ 30min, oil surface temperature ≥ 200 ℃, and the temperature of the blank tank wall ≥ 300 ℃ fully developed fire, this kind of three-phase composite foam liquid has better coverage, which can effectively prevent oil and gas volatilization, suppress The fire is suitable for a fully developed fire where the burning time of the oil surface is long, the temperature of the oil surface is high, and the heat radiation of the flame and the tank wall to the oil surface is very high, resulting in a short volatilization distance of the oil surface.

Embodiment 3

[0026] The three-phase compound foam liquid and its application, its fire extinguishing device and its use method are the same as in Example 1, except that the ratio of the gas-liquid phase foam liquid to the solid phase medium particles is 8:1-12:1 when the diameter is greater than or equal to 1 60m full area fire.

Abstract

The invention belongs to the technical field of fire prevention, suppression or fire extinguishment, and specifically relates to a three-phase compound foam liquid, and an application, a fire extinguishing device and a usage method thereof. The three-phase compound foam liquid comprises a mutually mixed gas-liquid phase foam liquid and a solid phase medium, wherein the solid phase medium is particles with air holes disposed therein. The fire extinguishing device comprises a gas-liquid phase foam liquid storage which is connected with a mixer of the foam liquid and the solid phase medium and a solid phase medium storage, wherein the gas-liquid phase foam liquid storage is also connected with a fire pump; the mixer of the foam liquid and the solid phase medium is connected with a gas-liquid-solid mixer through a high-powder pumping system; and the gas-liquid-solid mixer is connected with a nitrogen gas supply system. The fire extinguishing device can solve long-distance fire extinguishing problems for fighting full-area fire disasters of an oil tank, greatly increase the efficiency of fighting full-area fire disasters of the oil tank, can overcome the disadvantage of low fire extinguishing efficiency, can extinguish the long-distance fire effectively, has high fire extinguishing efficiency, and is safe in operations.

Description

technical field [0001] The invention belongs to the technical field of fire prevention, suppression or extinguishment, and specifically relates to a three-phase composite foam liquid for extinguishing a full-area fire in an oil tank, its application, its fire extinguishing device and its use method. Background technique [0002] When a full-area fire occurs in an oil tank, the flame body is huge, and the tank wall above the liquid level is strongly roasted by the flame, making the tank wall temperature very high, which often leads to damage to the fire-fighting facilities installed on the top of the tank wall. The full-area fire of such an oil tank usually needs to rely on mobile fire-fighting equipment. At present, mobile foam cannons are commonly used at home and abroad. However, with the increase of the diameter of the oil tank, the burning area increases at a quadratic rate. The main difficulties are: (1) The heat radiation of the flame is serious, especially for large o...
