Three-phase compound foam liquid, and application, fire extinguishing device and usage method thereof

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...
