A kind of instant novel fire extinguishing method for producing gas, specifically, first ignite gas generating agent, produces immediately after being ignited using gas generating agent
Raw high pressure gas pushes extinguishing chemical to spray outward as the power source of ultra-fine dry powder extinguishing agent, and in pushing course mesohigh
Gas is sufficiently mixed with extinguishing chemical, so that extinguishing chemical is wrapped gas molecule and is formed high-pressure mixing fluid, when flowing through convergence type channel,
It discharges after gathering pressurization in convergence type channel through narrow nozzle high-pressure, puts out a fire to scene of a fire total flooding.
Further limit, the narrow spout is multiple, and the flow direction of injection direction and high-pressure fluid intersect, form 2
~20 ° of angle makes high-pressure fluid change flow direction after the pressurization of convergence type channel, forms a plurality of spray post and tilt from narrow spout
Injection is put out a fire to scene of a fire total flooding.
It further limiting, the high-pressure fluid changes flow direction after convergence type channel is pressurized and sprays from narrow spout eddy flow,
It puts out a fire to scene of a fire total flooding.
It further limits, the gas generating agent is made of nitrate and melamine and catalyst, wherein nitrate
Mass percent is 68%~73%, and melamine is 18%~25%, and catalyst is added to 100%.
It further limits, the nitrate is potassium nitrate, sodium nitrate or strontium nitrate or any combination thereof；Catalyst is phenolic aldehyde
Resin or epoxy resin or unsaturated-resin.
It further limits, the mass ratio of the gas generating agent and extinguishing chemical is 1:2~10, preferably 1:3~6.
It further limits, the extinguishing chemical is dry powder fire extinguishing agent or fire foam.
It further limits, the dry powder fire extinguishing agent is sodium bicarbonate powder, sodium salt dry powder, sylvite dry powder, ammonium dihydrogen phosphate
