Description

Supersonic Gas colloidal sol dry powder Automatic Fire Extinguisher
Affiliated technical field
The present invention relates to a kind of fire fighting extinguisher, the colloidal sol of the Supersonic Gas efficiently dry powder Automatic Fire Extinguisher of especially safe and reliable, environmentally safe.
Background technology
In fire-fighting equipment, the application of dry powder extinguishing installation is very extensive.Because the granularity of common powder extinguishing agent is between the 45-50 micron, the dispersivity of this particle is poor, and specific area is relatively low, and extinguishing ability is also just very limited, and then has limited the scope of application of powder extinguishing agent.Therefore, preparation can evenly disperse in the space that catches fire, floating superfine powder is the effective ways that improve dry-chemical fire extinguishing usefulness, is the developing direction of powder extinguishing agent.It is reported that it below 5 microns is being the superfine powder extinguishing chemical of base-material with the saleratus that Britain has developed granularity, and done total flooding fire extinguishing experiment, its fire extinguishing effectiveness be common powder extinguishing agent 6-10 doubly, fire extinguishing effectiveness improves greatly.The preparation method of this superfine powder is varied, and mechanical crushing method and chemistry and physical method are arranged, and is wherein the most representative with hot aerosol fire-fighting technique and the cold air sol fire-fighting technique implemented abroad.The nineties, Russia has at first developed a kind of oxygen solid fuel that contains, and with the smoke fire extinguishing that solid fuel ignition is produced, this extinguishing chemical is called hot-gas sol fire extinguishing agent.Though the fire extinguishing effect of this extinguishing chemical is fine, the pyroreaction that produces in the fire extinguishing procedure has the danger that causes once more fire, has poisonous and defective such as corrosion.For solving this defective, people are developed into the cold air sol fire-fighting technique that does not produce high temperature in fire extinguishing procedure again, develop cold aerosol fire extinguishing agent.In the cold air sol fire-fighting technique, the cold air sol fire-fighting technique that people are studying at present and preparing to use is by the plant produced superfine powder, is transported to the flameproof protection scene through storage, and the injector of packing into is treated ejecting extinguishing when on fire.But in enforcement and operating process, the superfine powder of plant produced because the easy generation of the nano sized particles in the powder is reunited again, greatly reduces the fire extinguishing effect in storing transportation and wait process.
Summary of the invention
For the production that overcomes existing powder extinguishing agent fire extinguishing weak effect and superfine powder separates the easy defective of reuniting again of the superfine powder particle that is brought with the use strange land, the purpose of this utility model is to utilize the supersonic flow pulverization principle, design and a kind ofly collect raw material storage, process and be sprayed on the independently aerosol dry powder extinguisher of one automatically, the generation and the fire extinguishing of Supersonic Gas colloidal sol dry powder are carried out synchronously, avoid superfine powder in the reunion again that stores, transportation takes place effectively, brought into play the cold aerosol fire extinguishing agent special advantages effectively.
The technical scheme that its technical problem that solves the utility model adopts is: design a kind of Supersonic Gas colloidal sol dry powder extinguisher, be made up of pressure vessel, compressed gas cylinder, power initiating device and supersonic speed aerosol generator.The pressure vessel external form is an annular container, and inside is the dry powder storehouse, and fire-fighting powder is housed; The top of annular container and bottom are equipped with adpting flange and fixed sleeving and sealing block respectively, and sidepiece is equipped with the dry powder charge door; The supersonic speed aerosol generator is positioned at annular container, by the attaching nut respectively with upper end adpting flange and lower end sealing block on tube connector be tightly connected, be fixed on the axis in the annular container; Compressed gas cylinder is tightly connected by connecting thread and the adpting flange in the outlet of below, is fixed on the outer top of annular container axis, and the gas vent of compressed gas cylinder is equipped with seal membrane; The power initiating device is fixed on the outer bottom of annular container.Be loaded on the hollow cylinder of supersonic speed aerosol generator in the annular container for vertically installing, last lower section is according to each circumferentially even distribution 6-12 diffuser pipe of dry powder consumption, the footpath of shouting of diffuser pipe is 2-4mm, the outlet latus rectum is 3-5mm, the exit is the impact comminution chamber, pulverizing chamber communicates with discharge tube, and discharge tube passes the sealing block of annular container bottom to the annular container outside, and the lower end of discharge tube is the aerosol nozzle.The power initiating device is made up of puncture draw point, compression spring, fusible alloy bonding pad and bracing frame, puncture draw point lower end is connected with fusible alloy bonding pad on being fixed on bracing frame by tension wire, the central passage that connects adpting flange, supersonic speed aerosol generator and sealing block is passed in puncture draw point upper end, near the seal membrane of compressed gas cylinder gas outlet, and be supported in the central passage by the compression spring that is installed in the adpting flange.When the breaking out of fire on every side of this Supersonic Gas colloidal sol dry powder extinguisher, the fusible alloy bonding pad at first fuses, so the puncture draw point punctures the seal membrane of compressed gas cylinder under the effect of compression spring, Compressed Gas just enters the dry powder storehouse at once, in the dry powder storehouse, form two phase flow, make dry powder activating, enter the diffuser pipe of supersonic speed aerosol generator, enter pulverizing chamber behind the acquisition acceleration and form powerful convection current collision, be suspended in powder in the air-flow through phase mutual friction and collision and be ground into superfine powder, the place compiles at discharge tube, and immediately by the nozzle ejection, forms the alleged Supersonic Gas colloidal sol powder extinguishing agent fire extinguishing of the utility model.The realization of technical solutions of the utility model also must be adopted suitable compressed gas source, can use the compressed gas cylinder of nitrogen or carbon dioxide.
The beneficial effects of the utility model are, the supersonic flow pulverization principle is applied to dry powder extinguisher, common powder extinguishing agent is pulverized at fire-extinguishing location be processed into superfine powder, and fire-fighting efficiency improves several times than common powder extinguishing agent; Owing to Supersonic Gas colloidal sol dry powder extinguisher collection raw material storage of the present utility model, process and be sprayed on one, make the generation of Supersonic Gas colloidal sol dry powder and use and to carry out synchronously, avoided effectively and solved that the equipment investment that unsafe factor that existing hot aerosol fire-fighting technique exists and cold air sol fire-fighting technique exist is big, superfine powder stores the defective that transportation is reunited easily again.It is simple and compact for structure, and is with low cost, installs according to actual needs promptly can be used for the localised protection system; Also can be used for total flooding system, be suitable for very much unattended fire and explosion hazard area, have good economic benefit and important social benefit.
The present invention is further described below in conjunction with drawings and Examples.
