Description
Technical field
The present invention relates to Safety of Coal Mine Production technical fields, and in particular to a kind of temperature sensitive the anti-of dynamic release carbon dioxide is gone out
Fiery material and application method.
Background technique
Major casualty one of of the coal spontaneous combustion fire as mine and exploitation mine, it is not only to coal resources, production equipment
Cause serious destruction with atmospheric environment, generate a large amount of greenhouse gases, at the same also can the quick-fried gas and coal dust of firing point, cause various bright
Fire burning, can all cause a large amount of casualties every year.At present for coal spontaneous combustion fire Prevention Technique mainly have isolation or
Lower oxygen concentration, such as note nitrogen, injection CO2, wind leaking stoppage, note yellow mud and using the technologies such as resistanceization.Wherein, yellow mud is infused
It is mainly aqueous in yellow mud, cooling effect can be played and form a protective layer on the surface of coal, play starvation
Effect；Note nitrogen and carbon dioxide injection primarily serve the effect for reducing oxygen concentration, but since nitrogen is lighter than air, hold very much
It easily racks away, is not suitable for handling low level coal spontaneous combustion, and carbon dioxide is bigger than air specific weight, and is capable of the injection of rapid, high volume
High-temperature area, the ability being adsorbed in coal body is strong, is easy to be retained in goaf for a long time, therefore it is dense to inject CO 2 reduction oxygen
The method of degree administers in flame range or high-temperature area and shows very big advantage.But since carbon dioxide is also gas, very
Protective action is played in the region for being easy to disappear with mine air, therefore be difficult for a long time to protect needs, therefore how by two
Carbonoxide is fixed on the region for needing to protect, and can discharge carbon dioxide when zone of protection temperature increases and carry out fire extinguishing
To be very significant.Meanwhile a large amount of CO2 can also be fixed in underground goaf using such method, once coal body quilt
These CO2 will be enclosed in for a long time underground after extraction, also function to certain effect to greenhouse gas emission is reduced.
Summary of the invention
The purpose of the present invention is to provide a kind of temperature sensitive dynamic release carbon dioxide fire prevention and extinguishment material and its application method, with
It solves the problems, such as to be easy to escape with the wind using conventional method carbon dioxide injection.The material can absorb solidification a large amount of two at normal temperature
Carbonoxide is used for the region for needing to protect according to application method provided by the invention, when the regional temperature for needing to protect is normal,
Carbon dioxide contained by material will not escape, and after needing the coal temperature that protects to increase to be more than specific temperature, can be by
Carbon dioxide is gradually discharged, fire extinguishing is played the role of.
One of task of the invention is to provide a kind of fireproofing extinguishing materials of temperature sensitive dynamic release carbon dioxide.
A kind of fireproofing extinguishing materials of temperature sensitive dynamic release carbon dioxide are by capableing of ionic liquid, the alcohol of absorbing carbon dioxide
Amine, surfactant and water composition, wherein the ratio of the total absorbing liquid of ionic liquid Zhan is 5%-15%, and alcamines absorbent Zhan is total

The ratio that agent Zhan always absorbs liquid is 5%-15%.
The surfactant is mainly neopelex or lauryl sodium sulfate.Account for the ratio of absorbent
It is 0.5%.
Further, the material at normal temperature can a large amount of absorbing carbon dioxides, absorbability 0.15-0.2mol/
mol。
The initial temperature of the further material release carbon dioxide is 75 DEG C -80 DEG C, as the temperature rises, release
The rate of carbon dioxide is gradually increased, and when temperature reaches 100 DEG C -120 DEG C, the rate for discharging carbon dioxide reaches maximum.
After the further material release finishes carbon dioxide, the carbon dioxide in mine is can be absorbed in material again,
Realization is recycled.
Another task of the invention is to provide a kind of making for the fireproofing extinguishing materials of above-mentioned temperature sensitive dynamic release carbon dioxide
With method comprising following steps:
Step 1: configure carbon dioxide absorbent solution at normal temperature, by pyridine type ionic liquid (or its alloytype ionic liquid),
N methyldiethanol amine (MDEA) or other alcamines, water and surfactant pour into agitator respectively, match after mixing evenly
At absorbent solution；
Step 2: being passed through in the carbon dioxide gas to absorbing liquid of high concentration, and absorbing liquid absorbing carbon dioxide is allowed to reach
Saturation state；
Step 3: the carbon dioxide absorbent solution for being up to saturation state is transported to underground or is delivered to by grouting pipeline
Underground；
Step 4: using pump (either height difference and the pressure that is formed) by absorbing liquid according to adopt with note (spilling) or with note it is yellow
Mud is injected into goaf etc. by pre-buried Grouting Pipe together and needs fireproof region.
