Description
Technical field
The utility model relates to the agent of a kind of gas-solid mixing extinguish and anti-explosion, and what be particularly useful for that coal mine gas coal-dust explosion occurs in tunnel is datonation-inhibition, is also applicable to carry the back-fire relief in the industrial pipeline of the fuel gas with explosion hazard datonation-inhibition.
Background technology
Since founding of New, there is once the accident totally 24 of more than dead hundred people in colliery, the whole nation, causes 3780 people dead, wherein gas (coal dust) explosion accident 21, dead 3424 people, accident plays number and death toll accounting is respectively 87.5% and 90.58%." safety regulations in coal mine " specifies, highly gassy mine Driving Face in Coal Tunnel should be installed every (pressing down) quick-fried facility, and exploitation has the mine of coal seam liable to dust explosion, must have the measure of prevention and isolated coal-dust explosion.China makes remarkable progress at explosion-proof flame proof technical elements, as by the brainstorm project research such as country " six or five ", " the Seventh Five-Year Plan ", " eight or five ", " 95 ", have developed 6 kinds of passive type explosion isolation camps (i.e. explosion-insulating water tank fragility canopy, isolated blast water bottle canopy, moistureproof stone-dust barrier, explosion-insulating water tank foam canopy, XGS type explosion isolation camp and KYG type Quick-moving type explosion isolation camp) and 3 kinds of automatic explosion suppression devices (i.e. ZGB-Y type triggered barrier, the automatic air-generating explosion suppression device of ZYB-S type, YBW-1 type non-transformer trigger-type explosion suppression device).
Existing datonation-inhibition technology is all utilize to shoot down, throw or spray Explosion suppressant to realize datonation-inhibition function, and the Explosion suppressant used in various explosion suppression system mainly contains water smoke (or water) and powder two kinds.Chinese scholars research finds NaHCO
3the inhibition of powder to burning is good more than water smoke, and the inhibition adding the additives such as NaOH in water is better than pure water, and the effectiveness of explosion suppressions of powder body material to gas explosion such as phosphorus system, aluminium system and magnesium system are NH

Be not difficult to find by carrying out labor to these Explosion suppressants, a kind of composition of powder is only had in the good Explosion suppressant of current effectiveness of explosion suppression, it does not have the ability of dilution pernicious gas, combustable gas concentration can not be reduced, although datonation-inhibition effect may be played, but pernicious gas still may cause a large amount of casualtiess, also likely there is subsequent explosion if fuel gas runs into new burning things which may cause a fire disaster or repeatedly explode.
Summary of the invention
Technical problem: the purpose of this utility model is the weak point overcome in prior art, provides a kind of gas-solid mixing extinguish and anti-explosion agent can extinguished explosive flame, suppress shock motion, dilute fuel gas and pernicious gas.
Technical scheme: gas-solid mixing extinguish and anti-explosion of the present utility model agent, comprises high-pressure inert gas and ABC powder extinguishing agent; Described high-pressure inert gas is stored in high pressure inert gas cylinder, and the opening of high pressure inert gas cylinder is connected with the air inlet port of reducing valve, and the gas outlet of reducing valve is connected with one end of high-pressure rubber pipe, and the other end of high-pressure rubber pipe is connected with the bottom of storage tube cell; Described ABC powder extinguishing agent is stored in storage tube cell, and ABC powder extinguishing agent is full of whole storage tube cell; Described high-pressure inert gas sprays together with described ABC powder extinguishing agent through reducing valve, high-pressure rubber pipe, storage tube cell, forms the agent of gas-solid mixing extinguish and anti-explosion.
Described high-pressure inert gas is high pressure nitrogen or high-pressure carbon dioxide.
Beneficial effect: only have a kind of composition of powder at present in the good Explosion suppressant of effectiveness of explosion suppression, it does not have the ability of dilution pernicious gas, can not reduce combustable gas concentration.The utility model overcomes these deficiencies, and the gas-solid mixing extinguish and anti-explosion agent provided can not only extinguish explosive flame completely, suppresses the propagation of once exploding, can also dilute pernicious gas, stops the propagation of repeatedly exploding.ABC powder extinguishing agent of the present utility model fully can contact with gas fuel burning or the flame front formed that explodes, and absorbs the energy of flame in a large number and stops elementary reaction chain, making fray-out of flame, thus stops flame continuation forward direction.After burning or blast are successfully suppressed, the existence of high-pressure inert gas can dilute the gas in restricted clearance, make combustable gas concentration lower than explosion ratio lower limit, prevent fuel gas from secondary being occurred by lighting again or repeatedly explodes, the reduction of harmful gas concentration can reduce the injures and deaths of personnel in restricted clearance, remaining ABC powder extinguishing agent is deposited in bottom restricted clearance, once there is secondary or repeatedly explode, when prodromal blast wave is transmitted to this region, the ABC powder extinguishing agent be deposited on bottom restricted clearance is kicked up, Eddy diffusion in atmosphere, and fully contact with the flame front of rear arrival, make fray-out of flame, suppress subsequent explosion or repeatedly explode to continue forward direction.
