Specific implementation mode
It is an object of the invention to overturn from firecrackers production technology, on the guaranteed basis of the firework display effect of firecrackers
On, the pollution of air and environment, the principle of the present invention will not be caused to be, the burning things which may cause a fire disaster formed by lead 1 causes capsule 5 broken
While splitting so that the explosion medium 6 in capsule 5 generates explosion.3 to 4 pairs of the preferred embodiment of the present invention below in conjunction with the accompanying drawings
It is described further, the present invention includes lead 1, sealing end 2, cylinder 3 and back cover 4, is additionally provided with capsule 5 in cylinder 3, in capsule 5
Setting explosion medium 6；Lead 1 is contacted with capsule 5.
Under room temperature, explosion medium 6 includes non-combustible gas either fuel gas either flammable liquid or flammable solid
The mixed gas that body or non-combustible gas are constituted with fuel gas；
When lead 1 burns broken capsule 5, explosion medium 6 generates explosion phenomenon.
A diameter of the 1 to 2mm of the capsule 5；Length is 2 to 4mm.
When the medium 6 that explodes is non-combustible gas, the air pressure in capsule 5 is more than air.Embodiment one, such as air, in pressure
Compressed gas is formed under effect；Embodiment two forms liquid under pressure such as dry ice；
When the medium 6 that explodes is fuel gas, the air pressure in capsule 5 is equal to or more than air；Embodiment three, such as hydrogen.
When the medium 6 that explodes is the mixed gas that non-combustible gas and fuel gas are constituted, the air pressure in capsule 5 is equal to or greatly
In air；Example IV, as air is mixed with hydrogen.
When the medium 6 that explodes is flammable liquid or flammable solid, the air pressure in capsule 5 can not be considered；Embodiment five, such as makes
With ethyl alcohol and black powder.
It is additionally provided with connector sleeve 7 between the front end and sealing end 2 of the capsule 5, connector sleeve 7 is fixed at the interior of sealing end 2
Wall, lead 1 is passed through from the through-hole 11 among connector sleeve 7, and is contacted with capsule 5.Connector sleeve 7 can ensure that lead 1 and capsule are close
Success rate is seted off in contact, raising.
It is additionally provided with cushion block 8 between the rear end and back cover 4 of the capsule 5, cushion block 8 is fixed at the inner wall of back cover 4, glue
Capsule 5 is fixed between cushion block 8 and connector sleeve 7.Cushion block 8 plays the role of further fixing capsule 5, it is ensured that lead 1 is tight with capsule 5
Contiguity is touched, and is further increased and is seted off success rate.
When setting off, combustion wire 1,6 expanded by heating of explosion medium in capsule 5 is put, and capsule 5 is exploded, caused simultaneously
Sealing end 2, cylinder 3 and back cover 4 explode, and generate the firework display effect of traditional firecrackers.
The factor of explosion limit is influenced, the explosion limit for the medium that explodes is influenced by factors, mainly had following several
Factor：
(1) temperature：The original temperature of mixture is higher, then lower explosion limit is lower, and the upper limit improves, and explosion limit range expands, quick-fried
Fried dangerous increase.This is because mixture temperature increases, internal energy of molecular increases, and causes the quickening of burning velocity, moreover, by
In the increase of internal energy of molecular and the quickening of burning velocity, keep the excess air (being less than lower explosion limit) contained originally or combustible high
In upper explosion limit, and the mixture concentration of propagation of flame cannot be made to be turned into the concentration that can make propagation of flame, to change
Explosion limit range.
(2) oxygen content：Oxygen content increases in mixture, and explosion limit range expands, and especially upper explosion limit improves more.Such as
The explosion limit that hydrogen is mixed with air is 4%~75%, and the explosion limit that hydrogen is mixed with pure oxygen is 4%~95%.
(3) inert media：If mixing incombustible inert gas in explosive mixture, as nitrogen, carbon dioxide, vapor,
Argon, helium etc. increase with the percentage of inert gas, and explosion limit range then reduces, and the concentration of inert gas is increased to a certain
Numerical value can also make mixture become not explosibility.Under normal circumstances, influence of the inert gas to mixture upper explosion limit compared with
Influence to lower limit is more notable, because inert gas concentration increases, indicates that the concentration of oxygen is opposite and reduces, and the oxygen in the upper limit
Concentration already very little, therefore inert gas slightly increases a bit, that is, produces a very large impact, and upper explosion limit is made acutely to decline.
(4) pressure：The reset pressure of mixture has a significant impact to explosion limit, and pressure increases, and explosion limit range also expands,
Especially upper explosion limit significantly improves.It is appreciated that when the reset pressure of mixture reduces, explosion limit range shorter,
When pressure is down to a certain numerical value, lower limit synthesizes a bit with the upper limit, and pressure reduces again, and mixture becomes not explosive.Explosion limit
The pressure that range shorter is zero is known as the critical pressure exploded.The presence of critical pressure shows to be subtracted in closed equipment
Press operation can exempt the danger of explosion.
(5) container or pipe diameter：Container or pipe diameter are smaller, and flame is more difficult to spread wherein, the explosion limit of mixture
Range is then smaller.When container diameter is small arrives a certain numerical value, flame cannot be spread, and can eliminate explosion danger, this diameter is known as
Cut off diameter.If the cut off diameter of methane is 0.4~0.5mm, hydrogen and acetylene are 0.1~0.2mm etc..
Influence of the container diameter size to explosion limit, can be explained with chain reaction theory.Burning is that free radical generates
A series of chain reactions as a result, caliber reduce when, free radical is corresponding to the collision probability of tube wall to be increased, when caliber is reduced to
When to a certain degree, i.e., the reaction speed of the destruction of free radical is more than the reaction speed that free radical generates caused by collision, and burning is anti-
Should just it cannot continue.
Various explosive mixtures all there are one minimum ignition energy, i.e. ignition energy, it refer to can setting off an explosion property it is mixed
Energy possessed by the minimum burning things which may cause a fire disaster that object explodes is closed, it is also an important performance ginseng of mixture explosion hazard
Number.The ignition energy of explosive mixture is smaller, fires dangerous bigger.
The area of hot surface, the time of contact etc. of burning things which may cause a fire disaster and mixture, have an impact to explosion limit.In addition, light is to quick-fried
The fried limit also has an impact, as previously mentioned, hydrogen and chlorine mixing, react very slow, but under strong illumination then being protected from light at dark
There need to be dedicated fireworks product means of transport to transport when vigorous reaction (chain reaction) occurs and causes to explode, therefore transporting storage
Defeated and dedicated memory space storage.
