Described extinguishing material takes packaging measure;
Or above, on basis, this packaging measure is met fiery calcination or met high temperature and can automatically terminate, or can regularly remove, or time delay can to automatically terminate after input, or can clash into trigger removes.
Details are as follows for technique scheme:
The inner extinguishing material placed is a large amount of naturally occurring sand of nature, soil or stone or forms husky, native or stone main component and non-flammable silica, aluminium oxide, iron oxide, carbonate, phosphate or silicate or aforementioned any material two kinds and above mixture.Husky, main component is silica (being commonly called as silica), at present to be used to fire extinguishing, and the fire kind of various situation can be widely used in, but only have artificial input at present during fire extinguishing, efficiency is low and operating distance is short, if thrown in conjunction with certain device, so just can the needs of a lot of fire-extinguishing applications, comprise the situation of Tianjin explosion accident.The a large amount of naturally occurring soil of nature, stone are also like this; main component due to sand is silica; chemism is low highly stable; soil, stone then maybe may comprise the higher material of some chemisms so operation strategies is fewer than husky owing to comprising, but are all no problem for main large harmful influence or common harmful influence substantially.Selection can be carried out in advance just passable according to the harmful influence accident that will tackle.Form husky, soil or stone main component and non-flammable silica, aluminium oxide, iron oxide, carbonate, phosphate or silicate (being also the main component of cement) or aforementioned any material also can play identical effect with husky, native or two kinds, stone and above mixture.These materials are in a large amount of natural existence of nature, abundance, with low cost, its granularity can be reduced to improve input efficiency, if particle is between 0.1 micron to 1 millimeter, this may need equipment more closely to process, but nature also exists some 0.1 millimetre-sized fine sand, fine earths, what granularity was less is suitable for spraying, and realizes spraying from nozzle by pressure (pressure that chemical reaction is formed or the pressure that high velocity air is formed); Particle also can be no more than between 10 centimetres being greater than 1 millimeter, and this just can be made by this kind of roughing equipment such as pulverizers, and what granularity was larger is generally not suitable for spraying, can with throwing, shed, the mode such as transmission throws in.Above-mentioned extinguishing material stable chemical nature, unlike more existing artificial extinguishing materials as sodium acid carbonate etc. is put for a long time apt to deteriorate, can long storage time and undergoing no deterioration.
Extinguishing device can be jettison device, emitter, flusher, tossed device or conveyer.Jettison device device this refers to throws toward high the device that (drop point is not limit) is employing mechanical energy simultaneously from low, as bow and crossbow and kinetic energy apparatus etc., kinetic energy apparatus refers to the device adopting the alternate manner (as electric energy, electromagnetic energy) outside mechanical energy chemical energy to make it to produce kinetic energy, and current magnetic artillery has experimental prototype.Emitter this refers to and adopts chemical energy to promote (as gunpowder vigorous reaction produces gas propulsive, fuel combustion propelling etc.) as cannon etc., due to general gun tube limited diameter (exception such as torpedo tube/super large caliber mortar), the extinguishing material of large volume cannot be held, so the mode being similar to rifle grenade transmitting can be adopted to project this device.The device that extinguishing material goes out from nozzles spray by the pressure that flusher this refers to the forms such as pressure that the pressure formed by chemical reaction as the fire plants such as existing fire extinguisher, water cannon or high velocity air formed or hydraulic pressure.It is the device adopting mechanical energy (comprising hand push) that tossed device this refers to from height toward low throwing (drop point is certainly low than throwing point) simultaneously, as the water sprinkler on aircraft.Conveyer refers to that the transfer mechanism by conveyer belt or other form transmits the device of extinguishing material, and there are this device in streamline and sandstone factory, can by it miniaturization.
Extinguishing material also can be liquid nitrogen or dry ice or other and is cooled to liquid or solid-state incombustible gas.Nitrogen and carbon dioxide are also the common extinguishing materials naturally existed, common fire kind can be put out a fire by isolation oxygen, any fire can be put out a fire by lowering the temperature, therefore by the incombustible gas such as nitrogen, carbon dioxide its be cooled to liquid or solid-state after make extinguishing chemical, not only can lower the temperature but also can isolate oxygen, extinguishing effect is very good.
The above-mentioned extinguishing device for jettison device and conveyer is not containing the extinguishing material of gaseous material when also may be used for existing input, whether can produce gas and not do here to consider after input.Because existing fire extinguisher so its sphere of action of water cannon limited, and jettison device can increasing action distance greatly, realizes putting out a fire at a distance.The extinguishing device of conveyer mode is current also beyond example, but it is suitable for transmitting a large amount of extinguishing material fast obviously, disposes the most suitable employing of occasion at harmful influence fire.
Above-mentioned extinguishing device can add auxiliary agent as required, but with existing extinguishing device unlike, place auxiliary agent separately to have an autonomous container simultaneously auxiliary agent mixes with extinguishing material be from respective place container out afterwards and do not affect respective place container surplus materials, such extinguishing device can not be used after using once again, but can continue when needed to use.Also can not pile by the inner container placing extinguishing material, this is for the ease of mixing, if all piled, is unfavorable for mixing.Also the container of inner placement extinguishing material can be made replaceable, and container can be separated with affiliated extinguishing device, can change like this, instead of entirety is scrapped after extinguishing material is finished.Also the inner container placing extinguishing material can be made can to connect extinguishing material feed reservoir and therefrom obtain extinguishing material, directly connect sand drift as by conveyer belt or fill with the wagon box of sand, thus eliminate the limited limitation of extinguishing device self-capacity.Above-mentioned extinguishing material generally will process except sand, and make it particle smaller thus be convenient to throw in, the applicable flusher of particle diameter between 0.1 micron to 1 millimeter is thrown in, and is greater than 1 millimeter and is no more than 10 centimetres of devices being applicable to other types and throws in.
The auxiliary agent added above can be the material itself with fire-extinguishing function concurrently, as more existing extinguishing chemicals; Also can be can improve extinguishing material extinguishing property but itself do not have fire-extinguishing function concurrently material, such as contribute to realizing extinguishing material bonding and form tectal liquid, colloid (as silicone oil), also can be water at this auxiliary agent of occasion that can make to fire-fight by water, determine as required; Generally auxiliary agent weight or volume is no more than 25% of extinguishing material weight or volume, and auxiliary agent can not a presumptuous guest usurps the role of the host, does not use too many.Also innerly can place in the container of extinguishing material and there is pretreatment unit or auxiliary pretreatment unit, soil may make moist and be bonded to block in non-airtight situation, this servicing unit of blade that maybe can be able to carry out stirring by built-in agitator is processed by manual drive, makes it particle and diminishes.Also can exotic material such as refractory material, heat proof material etc. being adopted to make as nozzle, transfer mechanism front end the part of extinguishing device when putting out a fire likely close to burning things which may cause a fire disaster, so just closely can throw in extinguishing material, improving the accuracy of throwing in.
For the extinguishing device adopting jettison device form, extinguishing material generally should take packaging measure, is beneficial to throwing like this; Except flusher, the extinguishing device of other form also can take packaging measure.But generally, this packaging measure is met fiery calcination or is met high temperature and can automatically terminate, or can regularly remove, or time delay can to automatically terminate after input, or can clash into trigger remove, the coverage of packaged extinguishing material can be expanded like this, improve extinguishing effect.
According to the extinguishing device that technique scheme is made, the features such as raw material sources are extensive, with low cost, and also extinguishing effect significantly, not easily lost efficacy, and be particularly suitable for the fire of the specific type such as grade that chemicals causes.Form of simultaneously throwing in also has opened up several new model, can need to adopt flexibly according to fire extinguishing.
