In order to achieve the above objectives, the technical solution of the utility model is achieved in that
A kind of arragement construction for the fire extinguishing of coal dust storage warehouse, storage warehouse is interior to be equipped with spray head, and spray head is located at coal dust stacking
Bottom；The distance between two neighboring spray head is L1, and distance of the edge spray head apart from storage warehouse wall surface is L2；And between L1 and L2
Meet the following conditions:
L1≤2×L2 (1)
ρ1For the density of coal dust, kg/m3；
ρ2For the density of lumped coal, kg/m3；
D1For the partial size of pulverized coal particle, m；
D2For pipe-line diameter, m；
T is required time of penetration, s；
P is pipe-line pressure, Pa；

5×104< P < 3 × 105。
A kind of cooperation extinguishing chemical for the arragement construction of coal dust storage warehouse fire extinguishing, including following quality point as described above
Several components,
Tween-80 0.15%~0.25%；
Tetrasodium ethylenediamine tetraacetate 0.05%~0.15%；
Diisooctyl succinate sodium sulfonate 0.03%~0.08%；
Surplus is water；
The sum of mass fraction of each component is 100%.
Preferably, the component including following mass fraction, 0.2% Tween-80,0.1% tetrasodium ethylenediamine tetraacetate,
0.05% diisooctyl succinate sodium sulfonate and 0.1% solution of potassium carbonate；Surplus is water；The sum of mass fraction of each component is
100%.
In addition to being given above extinguishing chemical, it can also be put out a fire using other extinguishing chemicals, the above citing scope of application
It is not limited to above-mentioned extinguishing chemical.
Compared with the existing technology, the arragement construction described in the utility model for the fire extinguishing of coal dust storage warehouse, has following
Advantage:
The deepseated fire calamity that the utility model solves in pulverized coal bin is asked using traditional extinguishing chemical and fire-fighting mode are inextinguishable
Topic devises a kind of method from base injcction extinguishing chemical, and proposes sprinkler design in device according to specific extinguishing chemical
Formula can put out deepseated fire calamity to reach with the design of finishing device according to formula, protect mesh safe in coal dust storage warehouse
's.

Embodiment 1
A kind of arragement construction for the fire extinguishing of coal dust storage warehouse, storage warehouse is interior to be equipped with spray head, and spray head is located at coal dust stacking
Bottom；The distance between two neighboring spray head is L1, and distance of the edge spray head apart from storage warehouse wall surface is L2；And between L1 and L2
Meet the following conditions:
L1≤2×L2 (1)
ρ1For the density of coal dust, kg/m3；
ρ2For the density of lumped coal, kg/m3；
D1For the partial size of pulverized coal particle, m；
D2For pipe-line diameter, m；
T is required time of penetration, s；
P is pipe-line pressure, Pa；
The utility model also provides a kind of cooperation fire extinguishing for the arragement construction of coal dust storage warehouse fire extinguishing as described above
Agent, the component including following mass fraction, 0.2% Tween-80,0.1% tetrasodium ethylenediamine tetraacetate, 0.05% succinic acid two are different
Dioctyl sodium sulfosuccinate and 0.1% solution of potassium carbonate；Surplus is water；The sum of mass fraction of each component is 100%.
The size of coal dust storage warehouse is 4m*2m*1m, and storage coal dust is 300 mesh, and coal particle size is about 48 μm, coal dust density
For 500kg/m3, the density of coal cinder is 900kg/m3, internal firefighting agent pipe-line diameter is 6mm, can using formula (1) and formula (2)
It is as shown in the table to be calculated, the specific location of the spray head in coal dust storage warehouse can be arranged according to the distance in table.
Comparative example
Fire-fighting equipment in conventional coal dust storage warehouse can be divided into three kinds, and it is extinguishing chemical, spray head that the first, which is using water,
It is arranged at pulverized coal bin top center, sprays water after the heated opening of fire upper back spray head occurs, water is permeated from top, is led to
Experiment discovery (using experiment condition same as below, extinguishing chemical is only with water) is crossed, was only capable of infiltration 20cm by 10 hours, far not
Extinguishing effect can be reached.Remaining two kinds are respectively foam and carbon dioxide, penetrating power well below water infiltration, therefore it is conventional
Fire-fighting equipment and extinguishing chemical cannot achieve the purpose that put out pulverized coal bin deepseated fire calamity.
Experiment effect
One coal dust storage warehouse having a size of 5*4*4m is set, and inside is placed coal dust (300 mesh), set from coal dust bottom stacking
Spray head is set, the parameter of coal dust detects coal dust humidity using coal dust humidity sensor using the parameter in embodiment in experiment
Actual Time Of Penetration is obtained, the experimental results are shown inthe following table.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
Within the spirit and principle of utility model, any modification, equivalent replacement, improvement and so on should be included in the utility model
Protection scope within.
