Abstract
A CO2 gas fire-extinguishing agent conains components A and B, which are filled in a special fire extinguisher, "A" includes carbonic anhydride, corrosion inhibitor and defoamer and "B" is a mixture able to decompose carbonic anhydride. Its advantages include high volume of generated CO2 gas, high decomposing speed of carbonic anhydride, no poison and corrosion of dregs, and low cost.
Description
A kind of carbon dioxide gas fire-extinguishing agent belongs to the use of inhibition material.
Employed fire extinguisher mainly contains foam annihilator in fire-fighting at present, carbon tetrachloride fire extinguisher, and dry powder extinguisher and carbon dioxide extinguisher, their scope of application is all wide inadequately.The extinguishing chemical of foam annihilator institute filling is the aqueous solution of aluminum sulfate and sodium acid carbonate, can not be used for electric fire extinguishing; The extinguishing chemical of carbon tetrachloride fire extinguisher filling is the inert gas of carbon tetrachloride and pressurization, and carbon tetrachloride is poisonous, and gas also will partly resolve into hypertoxic phosgene in the fire extinguishing, diminishes health; The extinguishing chemical of dry powder extinguisher filling is the inert gas of ammonium salt, acid carbonate and pressurization, effectively attack time is short, and its powder, gas must fill respectively again, and need special equipment: carbon dioxide extinguisher is with prepared carbon dioxide, charge in the steel cylinder with high pressure, make it be the dry ice state and preserve, have system bottle technical conditions height, the expense costliness, the carbon dioxide source is stable inadequately in addition, general unit does not possess the condition of filling, and applies difficulty, can only be used for the fire extinguishing in special place.
Purpose of the present invention is to provide a kind of scope of application wide, and the carbon dioxide gas fire-extinguishing agent that conveniently fills.
Principle of the present invention is as follows: extinguishing chemical is made up of first, second two components, to contain the raw material of carbonic anhydride, as the first component, is loaded on the urceolus of special-purpose fire extinguisher after adding corrosion inhibiter, defoamer; Can make the mixture that contains the decomposition of carbonic anhydride raw material is the second component, is loaded on the interior letter of special-purpose fire extinguisher.During use, with mechanical means two groups of extinguishing chemicals of first, second are mixed in special-purpose fire extinguisher, moment promptly produces high-concentration carbon dioxide gas for fire extinguishing.
First component extinguishing chemical is formed and ratio is:
Acid carbonate: corrosion inhibiter: defoamer=100: 0.2～2: 0.1～1
The proportion of composing of second component extinguishing chemical is:
Inorganic acid: organic acid=1.5～9: 1
Fill in special-purpose fire extinguisher with extinguishing chemical of the present invention, it is big to have the carbon dioxide gas production during use, the characteristics that the carbonic anhydride decomposition rate is fast.And the extinguishing chemical raw material sources are wide, and cost is low, fill conveniently, do not need special equipment, and the residue after the use is nontoxic, the nothing corrosion.Special-purpose fire extinguisher with the can of extinguishing chemical of the present invention institute can be widely used in various fire extinguishings place, substitutes employed all kinds of fire extinguishers at present.
Embodiments of the invention are as follows:
The concentrated hydrochloric acid of measuring 24ml injects separatory funnel, takes by weighing 12 gram oxalic acid and pours in the separatory funnel that concentrated hydrochloric acid is housed, and make it fully stir, mix with concentrated hydrochloric acid.Take by weighing sodium acid carbonate 40 grams and pour in the flask, and add potassium bichromate 0.8 gram, octanol 0.5ml after mixing, will be equipped with the bottle stopper and the flask assembling of separatory funnel and wireway.With in the first group extinguishing chemical in the second group extinguishing chemical adding flask, notice that suitably the control reaction speed makes 10 liters of carbon dioxides to terminal approximately by separatory funnel.
