Description
Technical field
The present invention relates to a kind of training simulation fire point firearm.
Background technology
At present, outdoor simulated fire rehearsal construction project is mostly pure import Germany and Italian facilities, and igniter structure form is that air is naturally hybrid with combustion gas.The plane burner simulated fire fuel of more than 1 all adopts propane gas.Simulated fire ignition procedures；Lighter is lighted, plane fire fuel gas supply, light plane burner ejection propane fuel gas.Simulation flat flame is formed.Simulated fire examination person's field control is lighted or extinguishes.All processes adopts and remotely controls and have flame safety protection.Flame smog is little, environmentally safe.Because being that combustion gas fire is pollution-free to water vent almost without combustion residue, accomplish environmental protection.But simulated fire flame form and real scene fire disaster flame have gap, not fiercely.Equipment manufacturing cost is too expensive.Domestic simulated fire equipment is all domestic, simulated fire ignition procedures；Lighter atomization oil plant is lighted, plane burner (yi word pattern arrangement atomizer) fuel delivery is atomized first the atomizer atomized fuel forming, lighting plane burner closest approach firearm and lights the fuel oil (flat flame formation) of all the other atomizers ejection again with relay-type gradually.Flame profile is completely close to real scene of fire flame.Its shortcoming；Having residual fuel oil to pollute draining during hot drill, lighter wind loading rating is not ideal enough, and when training, outdoor wind-force is less than meeting simulation flat flame burning of igniting in light breeze speed 2 meters/S situation.Once the on-the-spot wind speed of training more than 2 meters/S, lighter fuel oil flame is obviously reduced or can not sustained combustion.After (its main cause owing to wind direction and wind velocity reason causes atomized fuel can not sustained combustion) causes atomization, fuel oil spreads towards periphery, and this phenomenon is breakneck.Even if lighter can form flame due to the impact of extraneous wind direction and wind velocity sometimes, ignition flame is obviously reduced, even if the atomized fuel of first atomizer ejection of plane burner can be lighted, fuel oil after being atomized due to all the other atomizers of wind direction effect has blowed to opposite side causes flat flame relay not ignite, and also just can not form plane burning.Fuel particles ballooning after unlit atomization, causes the atomized fuel sprayed and fuel oil-gas to fill the air everywhere, and this phenomenon may cause uncontrollable large area fire, is breakneck.Also having other similar devices, there is also lighter energy by observation too little, the flame after lighting cannot be sprayed more than 1.5 meters/S lighter by testing ground wind-force more than gentle breeze speed, also be impossible to light simulation plane fuel oil fire.Natural conditions are required too high.More than gentle breeze can not using, many lighters can not work again simultaneously, and fuel delivery mode adopts again dispersion supply type, and fuel nozzle is atomized and imperfection.Internal structure complexity maintenance load is big, is nearly at semiparalysis state, it does not have referentiability.
The simulation outdoor fire project fuel that Xinjiang fire-fighting army unit builds also is select fuel oil.Lighter adopts pure spark ignition simulation plane fire, owing to the ignition energy too low persistent period is short, and is again nude lighter, and this lighter caused by the geographical environment of Xinjiang absolutely not adapts in outdoor.Outdoor simulating training system for fire device can only manually be lighted a fire, and igniting people's danger is too big.Being only used for the small-sized fire device of lab simulation to use, namely enable and light simulation flame in indoor, lighter is little to reuse.With Single Maintenance once.Simulating and adopt oil tray to add a certain amount of fuel oil more than 2 outdoor ground fire, pure vapo(u)rability combustion flame fire is formed, sparking mode, adopts and manually lights.Simulated fire is not accomplished controlled, it is necessary to added fuel oil has all been burnt and could have been terminated, can not all burn even if burning terminates also to have 5-10% fuel oil, cause the residual fuel oil not burnt completely to pollute draining.
Summary of the invention
It is an object of the invention to provide a kind of training simulation fire point firearm, not only wind loading rating is strong, and device is reusable, safe and reliable, without combustion residue after burning, and non-pollution discharge.
The object of the present invention is achieved like this, a kind of training simulation fire point firearm, including airway and electrode, airway is the pipe or square tube that are made up of 316L rustless steel, one end of airway arranges flange, described electrode is feedback electrode and ignitor two, two electrodes and a skirt are separately mounted on flange, in the other end of airway, deflector is set, the working end of two electrodes is respectively provided with colored tooth, flower tooth is positioned at outside described deflector, distance between deflector and airway outboard end is that 20 50mm constitute the anti-air compartment of flame, combustion gas mixed flow room is constituted in airway between deflector and flange, described skirt is connected to compressed air hose and propane Gas Pipe, the volume ratio entering both the indoor compression air of combustion gas mixed flow and propane combustion gas is 1:1.25.
Described deflector is rectangle, and the top and the bottom of rectangular guiding plate are horizontally spaced about two row's burner ports respectively, and the diameter of burner port is 2 3mm.
Described deflector is circular, the uniform interval that is centrosymmetric on circular deflector arranges inside and outside two circle burner ports, and the quantity of outer ring burner port is 30, and the pore size of outer ring burner port is 3.5mm, the quantity of inner ring burner port is 12, and the pore size of inner ring burner port is 3mm.
In described airway, the length of combustion gas mixed flow room is 50 92mm, and the caliber of airway is 50mm.
It is as follows that lighter of the present invention obtains experimental data by experiment:
Specified criteria: fuel gas supply pressure 0.2Mpa, air pressure is 0Mpa.Igniter structure: air is naturally hybrid with combustion gas, is similar to family gas stove principle, high-voltage pulse spark ignition, and combustion gas mix gas flame mixed with air sprays from lighter nozzle.Combustion test process under windless condition；280W/800V ignition transformer is adopted to continue spark ignition mode.Fuel gas supply adopts 0.2MPa level pressure.Caliber area of section 78.5mm2Diameter 10mm metal tube, natural air inlet open area is from 19.5mm2To 1200mm2Adjustable, chamber diameter 40mm, degree of depth 10mm.Every 0.3 meter of lighter dead ahead adds 1 gasoline cotton balls.The igniting transformer-supplied when natural air inlet open area is transferred to minimum, in combustor, electric spark is formed continuously, opens gas valve, and combustor flame sequential is lighted sequential and extinguished, it is impossible to sustained combustion.At this moment adjusting natural air inlet open area so as to be gradually increased, flame is from intermittent burning to sustained combustion, and flame color is from redness gradually to yellow, and combustor flame sub-fraction is blue, and maximum flame stretches out combustor 100 millimeters.It is further continued for increase air-admitting surface flame color and the length of flame is constant.First, 0.3 meter of of dead ahead gasoline cotton balls is lighted, and all the other cotton balls cannot be lighted.Increase extraneous wind load test；As external wind velocity modulation to 2.0 meter/S, wind direction head-on wind (wind direction is just to lighter crater) igniter flame length is reduced to 20%, and 0.3 meter of gasoline cotton balls cannot be lighted, and as external wind velocity modulation to 3 meter/S, causes fray-out of flame or and has tempering phenomenon.When increasing lateral wind when angle (wind direction and lighter axis shape at 45 °) as external wind velocity modulation to 2.0 meter/S, flame is towards downwind knockdown, and the length of flame is reduced to 40%, flame has xanthochromia to become redness, and 0.3 meter of gasoline cotton balls cannot be lighted.Natural air inlet mouth is closed, and changes into and passes into electric spark power supply in forced air inlet (air inlet add 0.1-0.5MPa adjustable compression air) lighter and form lasting electric spark, opens air cock, open gas valve.Adjust compression air supply gas pressure (namely adjusting air quantity delivered) gradually, flame from intermittent burning to sustained combustion again to active combustion, flame color is again to blueness from redness to yellow, and blue flame ejection combustor, from 0.1 meter to 0.5 meter, makes continuous two the gasoline cotton balls burning of dead ahead.Again during increase air quantity delivered, flame changes to yellow from blueness and red will extinguish in increase air supply changing at once.When combustion gas is most suitable with compression AIR Proportional, increase extraneous wind load test；As external wind velocity modulation to 0-5.0 rice/S, igniter flame length is maximum is reduced to 50% for wind direction head-on wind (wind direction is just to lighter crater), and 0.3 meter of gasoline cotton balls normal ignition, as external wind velocity modulation to 8 meter/S, is that the length of flame is reduced to 20%.The gasoline cotton balls of dead ahead cannot be lighted.When increasing lateral wind when angle (wind direction and lighter axis shape at 45 °) as external wind velocity modulation to 0-5 rice/S, flame is towards downwind slight inclination, and the length of flame is reduced to 40%, and flame color is constant, can light 0.3 meter of gasoline cotton balls.Lengthen combustor effective length to 50mm, igniter flame wind loading rating 50% can be effectively improved.Front wind brings up to 0.6 meter, and side leading wind can bring up to 8 meters/S.The gasoline cotton balls at 0.3,0.6 meter of of normal ignition dead ahead.
Obtain a result by testing；When propane and air ratio are less than 0.68 can not sustained combustion, when propane and AIR Proportional 0.8, flame stabilization is near exit, flame gas flow velocity 0.5M/S.When propane burns formation blue flame completely, air consumption is the 125% of propane gas consumption, flame gas stream scooter 6M/S.Its result uses amount of oxygen to match with propane chemical molecular formula C3H8 phosphorus content substance combustion.
By above experiment conclusion.Adopting the lighter that propane makes fuel to adopt nature to suck its flow velocity that jets out flames of air type forever can not more than 0.5 meter/S.Its main cause naturally supplies air pressure and is always lower than gaseous-pressure, and match ratio is short of forever.Therefore combustion gas is fully burnt and is not forever reached, the super only 0.5 meter/S of combustion flame flow velocity, it is only applicable to indoor or without sustained wind wind light breeze 1.5 meters/S of speed, or has the obvious wind direction downwind that continues to make land used occasion.Otherwise light natural environment wind-force very big more than light breeze 1.5 meters/S of speed, more than 3 plane fire difficulty.
Airway of the present invention selects the 316L rustless steel of high temperature resistant resistance to high temperature corrosion.Reliability in order to ensure igniting is pollution-free, Fuel Selection propane combustion gas.Wind loading rating is increased, it is ensured that compression volume of air and propane combustion gas body ratio 1 in order to improve igniter flame air velocity；The ratio of 1.25 accurately arrives lighter mixed flow room and is sufficiently mixed, and enters combustion chamber by deflector, combustion flame by after the anti-air compartment of flame water conservancy diversion of certain length with 6 meters/S flame flow velocity blow-off point firearm.Even if head-on moderate breeze, 5 meters/S of wind speed blows out without by igniter flame.
