Technical field
This utility model belongs to technical field of mine safety, is specifically related to a kind of automatic explosion suppression device of coal mine gas.
Background technology
Some place of underground coal mine often occurs that methane accumulation is transfinited, especially corner on the coal-face of high methane coal mine
Angle, due to distinguished and admirable turning flowing the most smooth and distinguished and admirable turn round time produce the vortex phenomenon attraction to goaf gas, the most easily
Occur methane accumulation to transfinite, there is great potential safety hazard, gas explosion easily occurs.And in the market, existing press down
Destructor processed is mainly for the quick control after blast generation, but how just can suppress blast before gas explosion, both at home and abroad
All there is not preferable technological means.
Three primary conditions of gas explosion indispensability are: (1) gas density reaches between 5%～16%；(2) to have bright
Fire, the temperature of open flame source more than 650 DEG C；(3) oxygen in air to be had, air the most all exists, and this condition can be disregarded.
When the conditions are satisfied, gas could explode.
If but simply gas oneself blast, its power and lethality are not the most very big, only ignite coal dust when gas
Blast just shows its bigger lethality and destructive power together.Gas does not has explosive just as detonator, coal dust just as explosive, detonator,
Brisance is limited.Because coal-dust explosion produces 900 DEG C of high temperature above, produce powerful shock wave and substantial amounts of CO gas, and
Gas explosion produces CO2Gas.To this end, be not difficult to find out high methane coal mine work area upper corner or the suppression of other methane accumulation places
Gas explosion is the most critically important, but while suppression blast, if this place Dust Concentration can be suppressed the most critically important.

Detailed description of the invention
As depicted in figs. 1 and 2, the automatic explosion suppression device of coal mine gas of the present utility model, including being arranged on coal-getter
Make the infrared methane that the methane concentration at the upper corner 9 in face and at the upper corner 9 to coal-face detects in real time
Concentration sensor 7 and reduce gas density the fire-retardant aerosol apparatus 8 of depositing dust for spraying water smoke, and pass with infrared methane concentration
The controller 5 that the outfan of sensor 7 connects；Described aerosol apparatus 8 is by water pipe 4 and the electromagnetic valve 1 being arranged on water pipe 4, water
Pressure table 2 and water pump 6 are connected with water source 3, and described electromagnetic valve 1 and water pump 6 all outfans with controller 5 are connected；Described controller 5
On be connected to touch LCD screen 12, for detecting the Temperature Humidity Sensor of the humiture at the upper corner 9 of coal-face
10 with the ethernet communication module 11 for being connected with ground monitoring computer by Ethernet and communicate.
In the present embodiment, the model of described infrared methane concentration sensor 7 is GJH100.Described controller 5 for model is
The PLC module of S7-300.The model of described Temperature Humidity Sensor 10 is SHT11.The model of described ethernet communication module 11 is
CP243-1。
As in figure 2 it is shown, this utility model is applied at underground coal mine, underground coal mine, return airway 13 has outgoing airflow 14, enters
Having air intake lane distinguished and admirable 16 in air way 15, have work surface distinguished and admirable 18 in coal-face 17, coal-winning machine 20 is transported at coal-face 17
OK, the rear that coal-winning machine 20 runs is goaf 19.
During this utility model, water source 3 is arranged in return airway 13, owing to easily producing at the upper corner 9 of coal-face
Raw methane accumulation, therefore by infrared methane concentration sensor 7, controller 5, touch LCD screen 12, Temperature Humidity Sensor
10, ethernet communication module 11 and aerosol apparatus 8 are arranged at the upper corner 9 of coal-face, infrared methane concentration sensor 7
Methane concentration at the upper corner 9 of coal-face is detected in real time and the methane concentration signal detected is exported in real time
To controller 5, the methane concentration signal that controller 5 is received and methane concentration higher limit set in advance and methane concentration
Lower limit is compared, and when methane concentration is beyond methane concentration higher limit, controller 5 controls water pump 6 and starts, electromagnetic valve 1 dozen
Opening, the water at water source 3 is transferred to aerosol apparatus 8 by water pipe 4 after water pump 6 pressurizes, and aerosol apparatus 8 sprays high-speed and high-density water
Mist, gathers region churning to gas, make concentration transfinite gas disperse distinguished and admirable in take away, gas density reduces, and high speed is highly dense
Degree water smoke has also reached the purposes such as depositing dust is fire-retardant simultaneously, when methane concentration low to methane concentration lower limit time, controller 5 controls water
Pump 6 cuts out, and electromagnetic valve 1 cuts out, and water smoke stops injection.
In above work process, the humiture at the upper corner 9 of coal-face is carried out in real time by Temperature Humidity Sensor 10
The signal detected also is exported to controller 5 by detection, and controller 5 controls touch LCD screen 12 to methane concentration and temperature
Humidity shows in real time, it addition, controller 5 can also by methane concentration and humiture by ethernet communication module 11 and with
Too net is sent to ground monitoring computer, for the methane concentration at surface personnel's upper corner 9 to coal-face and temperature
The duty of humidity and the automatic explosion suppression device of this gas is understood.
The above, be only preferred embodiment of the present utility model, not impose any restrictions this utility model, every
Any simple modification, change and equivalent structure change above example made according to this utility model technical spirit, the most still
Belong in the protection domain of technical solutions of the utility model.
