What is the fire extinguishing principle of a fire extinguisher ball?

The fire extinguisher ball is a new type of firefighting equipment, with the progress of fire extinguishing technology, the use of fire extinguisher balls is also more and more frequent. So, what is the principle of a fire extinguisher ball?

What are the methods of fire extinguishing?

l Isolation method of fire extinguishing. The basic principle of the isolation method of fire extinguishing is the burning object, and combustible material for separation, or division. Burning without support, it can not continue to burn, and then gradually stop.

l Asphyxiation method of fire extinguishing. The basic principle of continuous combustion needs to have oxygen to fuel asphyxiation, fire extinguishing method is to prevent oxygen air into the combustion area, the burning material, and oxygen isolation, and then make the combustion can not continue, and gradually extinguish the fire.

l Cooling fire extinguishing method. The basic principle of the flame temperature below the fire extinguishing agent sprayed directly on the burning material, can make the temperature of the burning material down to below the ignition point, so that the burning stops, the most common is to use water to extinguish.

l Suppression fire extinguishing method. The basic principle of fire extinguishing agent and combustible materials for intimate contact, inhibit the production of combustible factors, so that the combustion reaction stops, the most common is the use of dry powder fire extinguishers to extinguish.

What is the fire extinguishing principle of a fire extinguisher ball?

The fire extinguisher ball device consists of a foam shell, an internal dry powder drive device, and ABC dry powder extinguishing agent. When the external fuse is ignited, the driving medium is activated and the shell rapidly expands and ruptures. The dry powder extinguishing agent is rapidly sprayed to the protected area and quickly diffuses around to form a fully submerged fire extinguishing state, and the flame is extinguished under the dual physical and chemical effects of the dry powder extinguishing agent. The basic principle of fire extinguisher ball extinguishing actually integrates the four methods mentioned above. First, the dry powder isolates the combustible material and combustible material, destroying the possibility of continuous combustion; secondly, the dry powder isolates the combustible material and air, so that the combustible material is isolated from oxygen and cannot continue to burn; then, the dry powder will react at high temperatures, not only to absorb heat but also to form salt and water to reduce the temperature of the combustible material, so that the temperature of the combustible material is reduced to below the ignition point; finally, the dry powder is in contact with the combustible material, inhibiting the combustible factors. To sum up, the fire extinguisher ball has a good fire extinguishing effect and can prevent the flame from reigniting to a large extent.
