Description
Technical field
The invention belongs to fire-fighting fire-smothering gear technical field.The physics cooling means that relates to chemical coolant in a kind of alternative condensed aerosol fire extinguishing device.
Background technology
Aerosol fire-extinguishing device is the fire extinguishing appliance that gets up in the fire-fighting domain new development in recent years.General structure is made of incendiary agent, chemical coolant, physics cooling agent and cartridge case thereof, thermal insulation layer, casing etc.
The mechanism of its fire extinguishing is the utensil that the mode that produces the flame in the certain limit around a large amount of aerosol gas total floodings when burning with incendiary agent reaches the fire extinguishing purpose.
The aerosol incendiary agent can go out a large amount of gentle bodies of high temperature fireworks in abrupt release during burning after igniter head igniting.In the small space of making cartridge case, must immediately these high temperature fireworks and gas cooled be got off.Therefore be provided with carbonate in the past the condensed aerosol fire extinguishing device and the synthetic chemical coolant of metal oxide is the cooling of the first order, the thermal-flame that produces during in order to control combustion agent moment burning and the expansion of gas.
Yet zinc carbonate, calcium carbonate, magnesium carbonate and the magnesia, calcium oxide, the crude zinc oxide materials that consist of chemical coolant all are to be pulverous material.Therefore meet moist environment, when jolting again or in transit trembled, just be bonded to one easily, be formed on the object that hardens like one deck shell on the splendid attire incendiary agent cartridge case.As on cartridge case, having added a loam cake.The high-temperature gas that this moment, this chemical coolant not only can not discharge at the instantaneous cooling incendiary agent, and fettered flowing of this gas.And cause simultaneously the surge of local pressure, the pressure that drives in the cartridge case raises, with incendiary agent and chemical coolant and upper strata physics cooling agent thereof together by suitable for reading all quick-fried penetrating of aerosol generator, thereby form secondary infringement.
Summary of the invention
Improvement on the technical pattern that the weak point that the present invention just exists for above-mentioned chemical coolant is made.Effectively having stopped aerosol fire-extinguishing device in the past causes the in-built incendiary agent of generator that quick-fried situation generation of penetrating occurs after the agent of igniter head ignition combustion because of the variation of chemical coolant.
Technical scheme of the present invention realizes: in-built among aerosol outer container 9, inner chamber bottom with the aerosol generator 5 of thermal insulation layer 6, interior Sheng incendiary agent 1 and igniter head 3 are housed to be reached except on the cartridge case 2 of grit chamber, contain in the past the chemical coolant part, change storage reason prompt drop agent 7, still put original physical cooling agent 8 on it and reach and stop aerosol fire-extinguishing device the quick-fried effective physics cooling technology that accident occurs of penetrating occurs.
This physics prompt drop agent is to be random banking up and to be consisted of by dozens of ceramic raschig rings (or metallic object make circulus).The mutual gap that they are banked up, and the circulation incendiary agent that the mesopore of circulus all can be unobstructed when burning the high temperature gas flow that discharges, and the gas flow temperature prompt drop that will flow through synchronously gets off, and the physics cooling agent that flows to the second level that is not blocked.
This physics cooling means has not only been stopped the quick-fried generation of penetrating accident of in the past aerosol fire-extinguishing device generation effectively, and high temperature and the gas process of more having avoided the past chemical coolant to produce when the cooling combustion agent is burnt are supervened new chemical gas and the possibility of contaminated environment.
Behind physics cooling agent instead of chemical cooling agent, produced when not only having reduced the aerosol fire-extinguishing device fire extinguishing occur to the pollution of environment with when stopping the aerosol fire-extinguishing device fire extinguishing quick-fried penetrate accident may, more real is: the process of producing in the past chemical coolant not only will expend a large amount of manpowers, and must see the face of God, only on fine day of sun Gao Zhao could the smooth calm place of airing at sheet.Not only waste of manpower teds repeatedly, more will waste a large amount of time and wait for the arrangement of God.So bring a lot of constraints for industrialized production aerosol fire-extinguishing device.Adopt after this kind physics cooling agent, this physics cooling agent can large batch ofly be bought in market, more can adopt the production in batch of industrialized means, therefore can significantly reduce the aerosol fire-extinguishing device production cost.
Description of drawings
Fig. 1 is the structural representation after aerosol fire-extinguishing device improves.Below in conjunction with the specific embodiment invention is described further.
The specific embodiment
The structure of aerosol fire-extinguishing device of the present invention is as shown in Figure 1: by outer container 9 and be positioned at the spout 10 on casing top and be contained among its body, periphery arranges the aerosol generator 5 of thermal insulation layer 6, and the chamber is loaded with propellant 1, igniter head 3 except the cartridge case 2 of grit chamber 4 within it, be provided with the physics prompt drop agent 7 that substitutes the past chemical coolant with its top, add that the physics cooling agent 8 that its top arranges consists of.
Wherein 7 of the physics prompt drop agent of instead of chemical cooling agent are to be made of dozens of ceramic raschig rings (or annular material of metal material and the making of other materials) random banking up.
After the incendiary agent 1 that is positioned at cartridge case 2 intracavity bottoms was lighted by the igniter head 3 above it, incendiary agent 1 will be via the physics prompt drop agent 7 of pouring into rapidly except grit chamber 4 above it at fireworks high temperature that abrupt release goes out and gas.
This physics prompt drop agent 7 is to be made of random the banking up of dozens of Raschig ring in the form of a ring.Therefore leaving the gap between ring and the ring, also there is the gap at the center of ring, enough incendiary agent 1 burnings
The time airflow process sent, simultaneously the gas temperature that flows through is reduced, also prevented that gas is bonded to piece at chemical coolant because of powder, retardance gas circulates fast the quick-fried accident of penetrating occurs.
After aerocolloidal air-flow has passed through physics prompt drop agent 7; continue the upper reaches; to flow to physics cooling agent 8 on it; carry out the cooling of the second level; temperature is reduced to get off again; the burning things which may cause a fire disaster that finally sprays the space of protecting towards periphery from spout 10 puts out its mode with total flooding, reaches the purpose of its fire extinguishing.
