Problems solved by technology

Of course, the powder fire extinguishing agent used in fire fighting is usually a substance with excellent solubility. Once it meets water, it will dissolve in large quantities, and its consequences are also very serious. Corrosive chemicals, the second is that the dissolution process may be relatively violent, prone to unexpected strong reactions or large amounts of heat

Abstract

The invention provides a fire-fighting device with an outward-extending powder spraying opening. The fire-fighting device with the outward-extending powder spraying opening comprises a water spraying nozzle 1 and a powder spraying nozzle 2, wherein the water spraying nozzle 1 is arranged outside the powder spraying nozzle 2 in a surrounding mode; and the powder spraying opening 4 of the powder spraying nozzle 2 is arranged in front of a water spraying opening 3 of the water spraying nozzle 1. The powder spraying nozzle 2 comprises a detachable extension pipe 11 arranged at the front part. According to the fire-fighting device with the outward-extending powder spraying opening provided by the invention, the technical bottleneck that sodium polyacrylate resin powder is used as a fire extinguishing agent in the prior art is solved, the sodium polyacrylate resin powder can be smoothly and continuously sprayed into a fire scene, and the powder spraying opening is not blocked.

Description

technical field [0001] The invention relates to the technical field of fire-fighting equipment, in particular to a fire-fighting device for powder fire extinguishing agent and liquid with an extended powder injection port and a method for spraying and mixing powder fire extinguishing agent and water. Background technique [0002] At present, water is still the most commonly used fire extinguishing agent, which has the advantages of being cheap, easy to obtain, and non-polluting to the environment. However, due to the good fluidity of water, most of the water will be lost after being sprayed on the fire site, resulting in waste, and for large-scale fires with a large fire area, rapid fire development, easy reflammation, and difficulty in extinguishing, water extinguishing can only control the spread of the fire. It is difficult to extinguish the fire in time and effectively. Although the dry powder fire extinguishing agent widely used now has improved fire extinguishing effe...
