Problems solved by technology

[0004] However, the fire extinguishing ball has the following disadvantages: 1. The production technology of the original product is complicated, and the production cost is high, so it is not suitable for large-scale and large-scale use; 2. It must rely on the driving medium during use, and the stability is poor

Abstract

The invention discloses a fire extinguishing bomb. The fire extinguishing bomb comprises an outer shell and an inner shell nested in the outer shell, wherein the outer shell and the inner shell are ofspherical structures, both the outer shell and the inner shell are made of elastic materials, the strength of the material adopted by the outer shell is larger than that of the inner shell material,the inner shell is filled with chemical substance NaHCO3 which is heated to release gas, a flame-retardant material is filled between the outer shell and the inner shell, the flame-retardant materialcomprises an aqueous solution of Al2(SO4)3, a foaming agent and a stabilizer, wherein the mass ratio of the Al2(SO4)3 to H2O, the foaming agent and the stabilizer is (40-45): (10-16):(3-8):(2-6), andthe mass ratio of the NaHCO3 in the inner shell to the Al2(SO4)3 located between the inner shell and the outer shell is (4-6):(3-4). The fire extinguishing bomb is suitable for forest fire and can quickly form an isolation belt.

Description

technical field [0001] The invention relates to the technical field of fire extinguishing appliances, in particular to a fire extinguishing bomb, a fire extinguishing method thereof and an application in forest area fire extinguishing. Background technique [0002] Fires in forest areas generally burn a large area. Human fire extinguishing with water not only has poor fire extinguishing effect, but also has great safety hazards. When the wind direction changes, it will pose a threat to the personal safety of firefighters. [0003] The Chinese patent of ZL201510384735.3 discloses a fire extinguishing ball device. The fire extinguishing ball is suitable for forest fire extinguishing. When the external lead wire is ignited, the driving medium is activated, the shell rapidly expands and ruptures, and the dry powder fire extinguishing agent quickly sprays to the protected area and spreads rapidly to the surroundings, forming a state of full flooding fire extinguishing. put out. ...
