Description
Technical field
The present invention relates to a kind of Explosion suppressant more particularly to a kind of powder Explosion suppressant for inhibiting coal-dust explosion and its preparation sides
Method.
Background technique
Coal dust is one of main disaster of coal production, it is not only as the inevitable outcome in coal production process
Cause occupational disease, endanger worker's health, and coal dust also has explosivity, once exploding, will cause casualties
And property loss, this seriously threatens the safety in production of mine.The datonation-inhibition technology of coal dust is to prevent and treat the important means of coal-dust explosion, suppression
Quick-fried technological core is the Explosion suppressant that research and development have preferable datonation-inhibition function.
Currently, the powder class Explosion suppressant for the inhibition coal-dust explosion that underground coal mine generally uses is rock powder, it is logical when coal-dust explosion
It crosses and broadcasts sowing rock powder to reduce oxygen concentration, thus achieve the purpose that inhibit coal-dust explosion flame propagation, however rock powder is easy by moisture knot
Block loses the ability of flying upward, and weakens the effect stamped out the flames, and causes the datonation-inhibition low efficiency of rock powder, datonation-inhibition function not good enough.
Therefore, it is necessary for developing a kind of powder Explosion suppressant that effectiveness of explosion suppression is good.
Summary of the invention
In view of the deficiencies of the prior art, to provide with datonation-inhibition function is good, dosage is few, high-efficient, preparation is simple datonation-inhibition
Agent, the invention proposes a kind of powder Explosion suppressants and preparation method thereof for inhibiting coal-dust explosion, and specific technical solution is as follows.
A kind of powder Explosion suppressant inhibiting coal-dust explosion, inhibiting the powder Explosion suppressant of coal-dust explosion includes parts by weight percentage

It is also preferred that aluminum sulfate octadecahydrate, aluminium carbonate, basic bismuth carbonate, tin bibromide, sodium methyl silicate, six inclined phosphorus
The diameter of particle of sour sodium is respectively less than 75 μm.
A kind of powder Explosion suppressant preparation method inhibiting coal-dust explosion, the powder for preparing above-mentioned inhibition coal-dust explosion are datonation-inhibition
Agent, step include:
Step 1 divides aluminum sulfate octadecahydrate, aluminium carbonate, basic bismuth carbonate, tin bibromide, sodium methyl silicate, calgon
It is not crushed, takes above-mentioned raw materials component grinding machine grinding to be sieved at powder, and with the sieve of 200 mesh respectively, collection screen
Under powder；
Step 2 proportionally weighs the lower sodium methyl silicate of sieve, calgon be added in powder stirrer be stirred 30~
It is uniformly mixed within 40 minutes, obtains powder 1；
Step 3 proportionally weighs the lower aluminum sulfate octadecahydrate of sieve, aluminium carbonate, basic bismuth carbonate, tin bibromide and dry powder is added and stirs
It mixes to be stirred 30~40 minutes in machine with powder 1 and be uniformly mixed；
Material after mixing is put into Constant Temp. Oven and is dried by step 4, and Constant Temp. Oven is according to 5
DEG C/heating rate of min from room temperature to 30 DEG C, then at 30 DEG C freeze-day with constant temperature for 24 hours after, it is quick-fried to obtain above-mentioned inhibition coal dust
Fried powder Explosion suppressant.
A kind of powder Explosion suppressant inhibiting coal-dust explosion provided by the invention has datonation-inhibition spy high-efficient, effectiveness of explosion suppression is good
Point.It is particularly suitable for inhibiting the explosion of underground coal mine coal dust.Form the various materials of the powder Explosion suppressant for inhibiting coal-dust explosion
Material plays a role from different explosion suppression mechanisms respectively, and a variety of materials synergistic effect is finally reached datonation-inhibition under a variety of comprehensive functions
Purpose.
Coal-dust explosion occur when, by it is described inhibit coal-dust explosion powder Explosion suppressant spray, when explosive combustion flame with
After the powder Explosion suppressant for inhibiting mine coal-dust explosion meets, aluminum sulfate octadecahydrate transient absorption heat decomposites mass crystallization
Water, the crystallization water is endothermic melting at liquid water, and liquid water continues heat absorption and flashes to vapor, since the specific heat capacity of water is very big, crystallization
The amount of heat of explosion time generation can be absorbed in this in the process for the endothermic melting evaporation of water, thus before quickly reducing coal-dust explosion
Flame temperature is driven, so that explosion forerunner's flame temperature is reduced to the minimum ignition temperature (MIT) of coal dust cloud hereinafter, finally making coal
Dust explosion can not be propagated；Meanwhile the aluminium that is generated after pyrolytic of aluminum sulfate octadecahydrate, aluminium carbonate and basic bismuth carbonate from
Son and bismuth ion can generate aluminium hydroxide and hydrogen-oxygen with maintaining reactive radical species OH necessary to burning to react in flame
Change bismuth, the aluminium hydroxide and bismuth hydroxide a part of generation can react with the H in flame generates water, and liquid water absorbs quick-fried
For the heat of vaporization generated when fried at vapor, the vapor collective effect formed with above-mentioned crystallization water evaporation makes Coal Dust group
Poly-, the Coal Dust after reunion can settle rapidly under gravity, so that the Dust Concentration in air is effectively reduced,
And the generation of vapor can be such that coal-dust explosion least concentration (MEC) rises, and Dust Concentration in air is finally made to be reduced to coal
Dust explosion least concentration (MEC) is hereinafter, terminate coal-dust explosion；The aluminium hydroxide and bismuth hydroxide endothermic decomposition of another part
At aluminium oxide and bismuth oxide, this not only greatly consumes reactive radical species OH and H, interrupts combustion reaction chain, Er Qiesheng
It can be attached to the surface of coal at object aluminium oxide and bismuth oxide, be allowed to and air exclusion, prevent its further combustion explosion.In addition,
Tin bibromide decomposes the bromide ion of generation at high temperature and the tin ion of divalent also to participate in the chemistry during substance combustion anti-
It answers, removes reactive radical species OH and H necessary to maintaining to burn, inhibit the reaction between these active groups, into
And combustion reaction chain is interrupted, inhibit burning, explosion to continue, while generating H2O, SnO, SnO further aoxidize generation
SnO2, partial oxidation is consumed, oxygen concentration, SnO are reduced2It is attached to the surface of coal, has completely cut off Coal Dust burning Shi Suobi
The oxygen needed, to prevent its further combustion reaction.
Meanwhile aluminium carbonate and basic bismuth carbonate can decomposite CO at high temperature2Gas, CO2The generation of gas can drop rapidly
Oxygen concentration in the gas of low latitude can be such that the oxygen concentration in air is reduced under coal-dust explosion limit oxygen concentration (LOC), reach
The effect of asphyxia finally can make coal-dust explosion that can not continue；And aluminium carbonate and basic bismuth carbonate are in decomposable process
A large amount of heat can be absorbed, can reduce air ambient temperature to inhibit flame transmission, further suppresses the biography of coal-dust explosion
It broadcasts.
Sodium methyl silicate in Explosion suppressant prevents that Explosion suppressant is during storage here, due to absorbing sky as waterproofing agent
Moisture in gas and lead to that Explosion suppressant fails or function reduces, greatly increase the service efficiency of Explosion suppressant, save replacement
Expense.As dispersing agent, during production, storage hardened, group occurs calgon in Explosion suppressant for anti-Explosion suppressant here
Situations such as poly-, and lead to Explosion suppressant function reduction.
