Description
Technical field
Chemistry, rescue
Background technique
Underwater breathing mainly uses compressed gas cylinder at present, and gas cylinder belongs to pressure vessel, and safety standard is high, and cost is also higher.
Summary of the invention
The present invention will provide a kind of emergency breathing equipment by chemical method manufacture oxygen and nitrogen.As making in short-term under water
The breath device used is entertained in industry and escape, the escape of poisonous and harmful hazardous gas environment personnel rescuing or excursion diving.Mainly
Storage cylinder is reacted by bite youngster, gas-guide tube, filtration core, multi-cavity, pharmacy response packet, reaction start button are constituted.
Detailed description of the invention
Fig. 1 emergency breathing equipment
Specific embodiment
Its main methods and step:
Oxygen and nitrogen are produced using chemical method, oxygen and nitrogen are for a person to use after mixing through mixing chamber.(oxygen
Nitrogen mixed proportion is in the acceptable range of human physiology).Its feature may be reused, for reacting the chemical drugs for generating gas
The form of medicine stick, medicine block, pack is made in product and reagent, accurate to match, to reach the mesh of control reaction speed and reaction time
's.
The method of chemical oxygen generation: inorganic peroxide oxygen content at most and easily discharges, such as sodium peroxide, calper calcium peroxide, mistake
Many inorganic peroxy compounds such as potassium oxide, barium peroxide, hydrogen peroxide.These peroxide in heat or meet water or meet it
When his chemical reagent, it is easy to precipitated oxygen.
Two examples are listed, are illustrated with intercommunity.
The reaction of sodium peroxide and water generates hydrogen peroxide first, and alkaline hydrogen peroxide is unstable to be decomposed.
Step 1: Na2O2+2H2O====2NaOH+H2O2；Step 2: 2H2O2====2H2O+O2 ↑, reaction
Heat release.
Overall reaction chemical equation: 2Na2O2+2H2O====4NaOH+O2 ↑
Calper calcium peroxide is reacted with water generates oxygen.Chemical equation: 2CaO2+2H2O=2Ca (OH)2+O2↑
In addition hydrogen peroxide oxygen: principle 2H2O2=====2H2O+O2 ↑ (catalyst: MnO2) can also be used
With catalyst-manganese dioxide and potassium chlorate is heated, chemical formula are as follows: 2KClO3=MnO2 is catalyzed and heats=2KCl+
3O2↑
The method of chemistry nitrogen:
Reactant is sodium nitrite (NaNO2) and ammonium chloride, and reaction condition is heating, and nitrogen is completely converted into nitrogen,
The type of reaction front and back element is constant, therefore there are also sodium chloride and water for product, therefore the equation reacted are as follows:
NH4Cl+NaNO2=NaCl+NH4NO2(heating)
NH4NO2=2H2O+N2↑ (heating)
Because ammonium chloride and sodium nitrite reaction are exothermic reactions, it is heated to 85 DEG C or so stopping heating, Yi Houke
The heat released by reaction maintains being normally carried out for reaction.
In addition sodium azide is heated, its thermal decomposition is made, very pure nitrogen, 2NaN can be obtained3===2Na+3N2↑
Also liquor natrii hypochloritis can be used to the solution NaClO+2NaN containing sodium azide3+H2O==NaCl+
2NaOH+3N2↑ auxiliary heat protocol principle:
Heating pack is mainly exactly quick lime, that is, calcium oxide add water after can generate calcium hydroxide, and discharge a large amount of
Heat.Chemical equation is as follows: CaO+H2O=Ca (OH)2
Heating pack heats up in 3-5 seconds at once after encountering water, and temperature can be made to be higher than 140 DEG C.
Heating condition needed for meeting manufacture nitrogen using the heat that manufacture oxygen process generates:
The reaction of sodium peroxide and water generates oxygen.Overall reaction chemical equation: 2Na2O2+2H2O=4NaOH+O2↑ reaction
Heat release.
Heating condition needed for meeting manufacture nitrogen using the heat that above-mentioned reaction generates.
Manufacture nitrogen reactant is sodium nitrite and ammonium chloride, and reaction condition is heating.NH4Cl+NaNO2=NaCl+
NH4NO2(heating) NH4NO2=2H2O+N2↑ (heating)
If attached drawing opens plug 3, it is intracavitary that the Drug packing of sodium peroxide and water is entered gas bottle 1, by sodium nitrite and chlorine
Changing the Drug packing of ammonium, to enter gas bottle 2 intracavitary, tightens plug 3；Rotational response triggers knob 4, successively starts oxygen and generates reaction
It generates and reacts with nitrogen, the nitrogen and oxygen for reacting generation pass through adsorption filter element 5 respectively and enters gas mixing chamber 6；Nitrogen and
Oxygen mixed in gas mixing chamber 6 after using adsorption filter element 7 and gas-guide tube 8 for breathing.
The effect of adsorption filter element is that a small amount of impurity for preventing pharmacy response, reaction from generating or bubble etc. overflow.Accurate meter
The dosage and proportion for calculating reaction drug, prevent from reacting insufficient or unbalanced reaction, prevent medicament from overflowing.
Oxygen and the proportional region of nitrogen mixing are the range for the human body short time being subjected to (not damaging to human body), full
Sufficient short time amusement and escape demand are target.
It reuses gas cylinder constantly, opens plug 3, the medicament packet more renewed, then tighten plug 3 again.
Reaction triggering knob 4, can be button, pull ring or knob in practice, and function is transmitting external force triggering medicament packet
Interior reactive material contacts with each other, and starts to react.
Oxygen and nitrogen are manufactured with the method for auxiliary heating
Assist heat protocol principle:
It needs to increase a cavity in gas cylinder, for containing the drug that can generate heat, the purpose is to produce by chemical reaction
Raw a large amount of heat is to the reaction heating for manufacturing gas, as long as being able to satisfy this purpose.
By taking quick lime as an example (substance that can generate exothermic reaction safely can all be applied), quick lime meets water and generates hydroxide
Calcium, while releasing big calorimetric.The chemical equation of quick lime and water reaction: CaO+H2O=Ca (OH)2Calcium oxide is reacted with water
It heats up at once in 3-5 seconds, temperature can be made to be higher than 140 DEG C.
Heating condition needed for meeting manufacture nitrogen using the heat that above-mentioned reaction generates.Manufacture nitrogen reactant is sub-
Sodium nitrate and ammonium chloride, reaction condition are heating.NH4Cl+NaNO2=NaCl+NH4NO2(heating) NH4NO2=2H2O+N2↑ (add
Heat) because ammonium chloride and sodium nitrite reaction are exothermic reactions, 85 DEG C or so stopping heating being heated to, it later can be by reacting
The heat of releasing maintains being normally carried out for reaction.
Other methods for being not belonging to exothermic reaction can be selected with the method for auxiliary heating and manufacture oxygen, manufacture the heat source of nitrogen
It is provided via additional heat release packet.
Such as calper calcium peroxide reacts with water and generates oxygen.Chemical equation: 2CaO2+2H2O=2Ca (OH)2+O2↑
