Heating wire is oxidized agent during dress（Such as overcritical oxygen）And reducing agent（Such as carbon dust or carbon black）Uniform attached collection, inflation thimble connects electricity
Source positive pole, inflation pedestal or expansion pipe outer wall connect power cathode, and being powered to heating wire makes the reaction material instantaneous expansion in energy-storing chamber
Break through expansion tube acting.
The acting principle of prior art gas fracturing device is that liquid carbon dioxide absorbs igniter（Activator）Discharge
Heat, make liquid carbon dioxide become high pressure expanding gas break through expansion tube constraint fracturing acting.
The acting principle of gas fracturing device of the present invention is：Oxidant chemically reacts with reducing agent, produces high compression swelling
Gas breaks through the constraint fracturing acting of expansion tube.
The reducing agent that the present invention is used is powdered, graininess or the thread solid-state of bar, or the liquid such as ethanol, glucose,
There is huge surface area and suction-operated, by being filled with 10-150MPa hyperbaric oxygen agents（Overcritical oxygen）, oxidant（It is super
Critical dissolved oxygen）Uniform adsorption is in reducing agent（Carbon dust or carbon black）On, the oxidant after absorption（Overcritical oxygen）With reducing agent（Carbon dust or
Carbon black）Generation chemical reaction produces high pressure expanding gas.Liquid carbon dioxide heat absorption more in the prior art produces high compression swelling gas
Body, the high pressure expanding gas produced that chemically react are bigger at least one times than inhaling thermogenetic high pressure expanding gas expansive force.
There are inflation thimble, inflation valve element and conductive pin on charge valve of the present invention, by setting air-filled pore on charge valve, fill
The cooperation of gas ejector pin, air-filled pore and sealing ring, realizes the function of inflation, sealing and conduction, realizes the purpose of inflation and igniting,
Charge valve is sintered using die casting or metal powder injection molded technology, simplifies two kinds of complicated structure sides of inflation and igniting
Formula, therefore the present invention directly reduces production cost with simple in construction.Used simultaneously using overcritical oxygen and carbon dust or carbon black ratio
The mixture cost of potassium hyperchlorate, potassium permanganate and aluminium powder is low.
As not having air-filled pore on charge valve, when filling oxidant, oxidant is at through hole gap and charge valve and valve pocket
Between gap at be filled into energy-storing chamber, impacting with high pressure charge valve and sealing ring after the completion of filling in energy-storing chamber, gases at high pressure
Gap between charge valve and valve pocket is caused sealing ring by impact breakage or deformation, caused close by rear impact sealing ring
Seal can not be sealed effectively with charge valve；The application on charge valve by setting air-filled pore, after the completion of filling in energy-storing chamber
Gap of the high pressure between charge valve and valve pocket impacts inflation hole site, and the pressure for making sealing ring by the pressure release of air-filled pore subtracts
It is small, therefore sealing ring by blastic deformation or will not break through；Because the sectional area for inflating valve element is big, the high pressure in energy-storing chamber concentrates on inflation
On valve element, the pressure release effect of air-filled pore is added, the inflated valve element of moment sealing ring for unclamping charge gun is pushed down, and realizes sealed mesh
, therefore air-filled pore in process oxidant is filled except playing a part of filling hole, is also acted as when terminating and filling to sealing ring
The effect of pressure release.
The composition of gas fracturing device of the present invention is mainly expansion tube and inflation igniter head, and what inflation and igniting united two into one is total to
Inflation and ignition structure are simplified with mode；Igniting is expanded by charge valve and inflation pedestal access power supply without lead is accessed
In pipe, therefore the structure that high pressure sealing processing is carried out to lead is eliminated, therefore inflation igniter head can be made very small, and overcome existing skill
Big and weight weight the deficiency of art volume.As prior art pneumatic head is installed.
Gas fracturing device is in transportation, only reducing agent, anaerobic agent, therefore produced in transportation in energy-storing chamber
Electrostatic or high temperature will not trigger gas fracturing device burn or fracturing.Fill the electrostatic meeting produced after oxidant in handling process
Sponged by heating wire, charge valve and expansion tube, it is to avoid occur from fracturing situation.
The igniter of prior art（Activator）Mainly mixed using solid oxidizer and solid state reduction agent（It is typically high
The strong reductant such as the strong oxidizers such as potassium chlorate and aluminium powder）The reaction material bag packed afterwards, heating wire is wrapped in mixture, fortune
During defeated easily occur reaction material stripped off with heating wire separate generation gap the problem of etc. cause generation miso-fire；It is of the present invention
Gas fracturing device, its heating wire is oxidized agent（Such as overcritical oxygen）And reducing agent（Such as carbon dust or carbon black）Uniform attached collection, transport
And handling process is stripped off with heating wire in the absence of reaction material and separates the problem of there is gap, when being powered igniting, heating wire produces high
Moment detonates after warm hyperpyrexia reacts with overcritical oxygen, realizes 100% effective detonation, and the generation that effectively prevent miso-fire is former
The danger of cause and row's miso-fire.
Gas fracturing device of the present invention, its reaction material carbon powder of reducing agent and the overcritical oxygen reaction of oxidant are violent, real
Existing oxidation reaction, its reaction product is mainly nontoxic carbon dioxide and a small amount of oxygen, pollution-free to expansion scene,
The poisoning hidden danger of field personnel can be prevented effectively from, because there is a small amount of oxygen not reacted after expansion, therefore can be shorter upon inflation
Recover construction operation in time, suitable tunnel is used.It can not recover construction in a short time after existing gas fracturing device expansion
Operation.
Expander of the present invention combines traditional gas expansion technology and liquid oxygen fracturing technology, compared to traditional
Expander, largely improves expansion power, compared to traditional liquid oxygen fracturing, and solving liquid oxygen fracturing can not be in normal temperature
The use environment limitation of necessary cryogenic freezing after the high risk existed under lower storage, normal temperature and inflation.
