The technical field to which the invention relates

This invention relates to a blasting method of exploding devices and, in particular, to a method of blasting exploding device, such as a chemical weapon, containing, at least, explosive and chemical substance.

The level of technology

Explosive in the explosive devices were used for General industrial applications, for example in the form of dynamite, as well as for military applications, such as chemical weapons (e.g., projectile, bomb, land and sea mines). Taking into account the resulting smoke after the explosion in an explosive, such as dynamite, in industrial applications was added to the oxidizing agent or the like to provide a positive oxygen balance in it or to prevent its too negative values. On the other hand, explosives for use in military applications, such as chemical weapons, have a negative oxygen balance to maximize their respective destructive forces. Additionally, chemical weapons contains a chemical substance dangerous for the body, such as sulfur mustard gas or lewisite, together with explosives.

The way the complete destruction of explosives by detonation in seeing enoy the processing phase is known as the processing method, containing an explosive substance of chemical weapons (see patent document 1). Subversive method is used for processing of chemical weapons, which shows significant corrosion and causes significant damage, and also has a complex structure, preventing the disassembly, and erosion usually occurs when chemical weapons were made in the pressure vessel. Chemical weapons containing chemical blowing up this way.

The way the complete destruction of explosives by detonation after dismantling chemical weapons and removal of chemical substances in the pre-treatment stage is also known as a processing method, containing the explosive chemical weapons (see patent document 2). The explosive method is used for treatment of chemical weapons, still retains its original external form, and explosive block, shot with chemical weapons, blow up when it is placed in the pressure vessel. Although most of the chemicals are removed in the disassembly operation, the explosive unit that still have stuck to it utverjdenie due to aging chemical substance, explode using this method.

In both the above explosive ways blasting preferably in a tightly sealed with the udah high pressure under vacuum for the following reasons:

(1) it is possible to prevent leakage of outside chemicals contained in the chemical weapons, because you can keep the pressure in the pressure vessel below (negative) the atmospheric pressure before the explosion, and after the explosion; and

(2) you can dramatically reduce the harmful effects on the environment caused by explosion, including noise and vibration.

The invention

Generally explosives are used in air in open or closed systems, and, thus, do not produce large quantities of soot after the explosion, because the oxygen comes from the air, even if the actual explosive has a negative oxygen balance.

However, when it explodes military explosives with negative oxygen balance, such as TNT, by undermining the pressure vessel, which can be created, essentially, a vacuum (hereinafter symbol "evacuated the pressure vessel"), generates a large amount of soot due to insufficient oxygen supply. On the other hand, the chemical substances contained in chemical weapons or chemical is a substance stuck an explosive unit, may not be fully decompose into its component parts explosion. Thus, inevitably creates soot contaminated chemical substance, when chemical weapons are exploding evacuated pressure vessel. Due to soot extremely small particles with very high probability can settle into the drainage system when the pressure vessel is cleaned decontamination agent, so that such explosive activity creates the problem of having to manually decontamination (removal of soot-contaminated chemical substance) or frequent maintenance, and hazardous work in the area of the contaminated chemical substance dangerous for the body. It also requires a long period of operation of decontamination after the explosion, causing a problem of limiting the number of blasting operations per day.

When military exploding device containing a chemical substance, such as chemical weapons, blow up by blowing into the evacuated pressure vessel, it is impossible to apply the oxygen amount necessary for combustion of explosives or just exploding device containing an explosive substance. As a result, the period of combustion of chemical substances at the time of explosion is reduced, causing a problem of deterioration of the decomposition of chemical substances, because carbon is Opochka, for example, sulfur mustard is less sensitive to oxidation.

The purpose of this invention is made considering the above problems, is the creation of an explosive way, which can prevent the formation of soot explosion and improve the efficiency of decomposition of chemical substances.

To overcome the above problems of the explosive method, according to the invention is a blasting method of exploding device containing at least an explosive substance and a chemical substance in a sealed pressure vessel, providing undermining exploding device by holding the pressure vessel under a reduced pressure or vacuum, and the pressure vessel contains the specific amount of oxygen that the oxygen balance in the pressure vessel becomes positive, and the pressure in the pressure vessel after the explosion remains below the pressure outside the pressure vessel.

"Oxygen balance in the pressure vessel" is expressed by the calculation amount (g) of oxygen required to convert the entire explosives in gases such as carbon dioxide, water vapor and nitrogen gas, when 100 g of exploding devices, including not only explosive, but also chemical and other, present the existing in the pressure vessel, explode. The state when the oxygen balance in the pressure vessel is a positive"means a condition in which there are oxygen atoms enclosed in a sealed pressure vessel before the explosion, sufficient, or more to convert explosives in gases such as carbon dioxide, water vapor and nitrogen gas, in the explosion. In this invention the oxygen balance is kept positive and preferably equal to about 20 g or more.

Additionally, a specific amount of oxygen is not limited particularly, if the number of oxygen atoms exceeds a specific value; oxygen can contain, for example, in the form of molecules, such as gas, oxygen or ozone, or in the form of compounds, such as sodium peroxide or peroxide of magnesium. That is, not particularly limited form of presence of the oxygen atom.

The state "under vacuum" means, essentially, the vacuum is obtained by pumping vessel using a vacuum pump, and, in particular, a state with a pressure of approximately 60 mm Hg (8.0 kPa) or less. The vessel under vacuum may contain gases such as air, nitrogen, oxygen, argon, helium and carbon dioxide. In this description, the state essentially vacuum" also means and vacuum.

Additionally, the capacity of the vessel is highly what about the pressure" not particularly limited, if it exceeds the volume of the gases generated by the explosion shattered the device, measured at normal temperature and atmospheric pressure. For example, the capacity is more preferably 30% or more of the volume of generated gases, measured at normal temperature and atmospheric pressure. In accordance with this, the pressure in the pressure vessel after the explosion" is not particularly limited, if it is below the pressure outside of the pressure vessel, but is preferably from 530 mm Hg (70,7 kPa) to 759 mm Hg (101,2 kPa).

"Explosion" means the operation of undermining the shattered device by detonation of explosives in the exploding device, and this firing method is already known and is not particularly limited, and examples include a method of ignition of exploding devices using flammable devices.

According to the method, by providing a positive oxygen balance just exploding device containing an explosive substance, you can convert carbon in the explosive substance to carbon dioxide or carbon monoxide and preventing the formation of soot in the pressure vessel after the explosion, and therefore, simplification of the deactivation of the pressure vessel and increasing the efficiency of the operation of the explosion. Additionally, the period of combustion chemical is someone substances during the explosion is extended, since before the explosion in the pressure vessel, there is oxygen in a quantity sufficient for combustion of the explosive, and the oxygen is consumed gradually only in the quantity required for combustion. Thus, for example, in the case of sulfur mustard its carbon chain is oxidized more slowly, and increases the efficiency of decomposition of the chemical. Additionally, the pressure inside the pressure vessel is supported by a lower (negative pressure)than the atmospheric pressure, even after the explosion.

Some or all of the outer surface of the pressure vessel may be provided with a coating to enhance security and sound insulation at the time of the explosion and the pressure outside of the pressure vessel can be kept at a value below atmospheric pressure. The pressure outside of the pressure vessel is set to a value that is relative to the pressure inside the vessel, and is arbitrary if it is not below the pressure inside the vessel.

The blasting method according to the invention is also not particularly limited, but preferably a specific quantity of oxygen is supplied, for example, in the form of gaseous oxygen. Thus, it is possible to regulate more than just oxygen balance of the explosive present in the pressure vessel, and the pressure inside the vessel is after the explosion, as well as reduce the cost of processing.

Preferably also serve part or all of a specific amount of oxygen in the form of oxygen contained in the compound of an alkali metal or alkaline-earth metal. Oxygen-containing compound of an alkali metal or alkaline-earth metal, most preferably a peroxide is a compound of an alkali metal peroxide or a compound of alkaline-earth metal. Examples of peroxide compounds of alkali metal include sodium peroxide, lithium peroxide, peroxide rubidium, cesium peroxide, etc. are Examples of peroxide compounds, alkaline-earth metal include peroxide, magnesium peroxide, barium, etc.

Thus, the atoms of oxygen from oxygen-containing compounds of alkali metal or alkaline-earth metal are released into the pressure vessel at the time of the explosion and supply the oxygen required for combustion of exploding devices, providing effects similar to those when gaseous oxygen is enclosed in the pressure vessel. In addition, for example, when using sulfur mustard, lewisite, or the like of an atom of an alkali metal or alkaline-earth metal contained in the oxygen-containing compound of an alkali metal or alkaline-earth metal, detoxifies Henichesk the e substance while the alkali metal atom contained in the oxygen-containing compound of an alkali metal or alkaline-earth metal, binds the chlorine atom in chemical education inorganic chlorine compounds.

Gaseous oxygen and oxygen-containing compound of an alkali metal or oxygen-containing compound of alkaline-earth metal can be used in combination as the source of supply of specific quantity of oxygen.

In the blasting method according to the invention, a specific amount of oxygen preferably is the amount of gaseous oxygen, the pressure of gaseous oxygen, is equivalent to between 15% and 30% of the atmospheric pressure at normal temperature.

The expression "pressure gaseous oxygen" means that all specific number of oxygen atoms present in the form of gas of oxygen (oxygen molecules), and the expression "pressure gaseous oxygen equivalent from 15% to 30% of atmospheric pressure" means the pressure of the gas of oxygen from 114 mm Hg (15.2 kPa) up to 228 mm Hg (30,4 kPa).

Due to the inclusion of oxygen atoms in a quantity equivalent to the pressure of gaseous oxygen from 15% to 30% of the atmospheric pressure at normal temperature, it becomes possible to prevent the image is of soot after the explosion and holding the pressure in the pressure vessel after the explosion below (vacuum) atmospheric pressure.

The preferred embodiment of the invention

First is a description of the chemical bomb chemical weapons as an example of exploding devices subject to explosion in the firing method according to this invention, with reference to figure 2. Figure 2 schematically shows a sectional configuration of a chemical bomb.

As shown in figure 2, the chemical bomb (exploding device) 100 is the tip 110, the bursting of the cylinder 111, the shell 120 bombs and controls the position of the tail Assembly 130. Explosive cylinder 111 contains a bursting charge (explosive) 112. The tip 110 has a fuse 113 to undermine bursting charge 112 contained in the discontinuous cylinder 111. The shell 120 bombs connected to the tip 110 and contains a bursting of the cylinder 111 and the liquid chemical substance 121. Controls the position of the tail Assembly 130 is located on the side opposite to the tip 110 of the shell 120 bombs, and controls the position of the chemical bomb 100 during the fall. The lifting ring 140 to connect the chemical bombs 10 when loaded into the aircraft is located on the upper shell 120 bombs.

Exploding device 100, processed in this invention, is the whole or part of the chemical bombs, containing at least the explosive 112 and chemical substance 121.

Exploding the device is not limited to the chemical bomb 100, in which the chemical substance 121 filled in the above manner, and the method is applicable also to the exploded device after dismantling chemical bombs explode when only the explosive unit in the pressure vessel. For example, as shown in figure 3, it is applicable also in the case when blow tip 100 and explosive cylinder 111 (explosive block 114) chemical bombs 110 after the separation membrane 120 bombs and removal of chemical substances. In this case, the tip 110 and the bursting of the cylinder 111 of the chemical bomb 100 often have deposits of the cured chemical substances adhering thereto, and thus is effectively used in this invention.

The examples used explosives include military explosives, such as TNT, picric acid, RDX (hexogen) and PETN (PETN). Examples of chemicals include skin neravnye substances such as sulfur mustard and lewisite, common toxic substances, such as DC (diphenylcyanoarsine) and DA (diphenylchloroarsine), phosgene, sarin, hydrogen cyanide, and the like.

The combination of explosives and chemical substances which STV is not particularly limited, but preferred are, for example, a combination of TNT and sulfur mustard gas, and TNT and lewisite as possible detoxification of chemical substances with the help of an explosion.

Below is a description of the outer explosive installation example installation for explosive exploding devices, such as the above chemical bomb 100, with reference to figure 1.

As shown in figure 1, the explosive installation 1 comprises an explosion chamber (pressure vessel) 10 and the casing 20 of the camera, containing inside the explosion chamber 10.

Explosion chamber 10 is resistant to explosions in the pressure vessel, made for example of steel and tough enough to withstand the explosive pressure during the explosion inside of him exploding device, such as a chemical bomb 100. Additionally, the explosion chamber 10 has an inside cylinder (not illustrated), which captures the shattered device, such as a chemical bomb 100, subject to blasting. Explosion chamber 10 has a removable resistant to the pressure of the cover 11 at its side. Resistant to pressure cover 11 is intended for oral administration transported exploding device, such as a chemical bomb 100, and the connection is not shown in the figure, the cylinder after its branches, and, on the other hand, to ensure explosion exploding device, such as chem is ical bomb 100, after connection and closing. The capacity of the explosion chamber 10 is sufficiently greater than the amount estimated under normal temperature and atmospheric pressure, of gases formed in the explosion of the explosive. Capacity by volume, preferably at least 130% of the maximum volume of gas, liquid or solid compounds, possibly formed during the explosion shattered.

At the top of the explosion chamber 10 is formed of multiple inputs 12 discharge. Injection inputs 12 made for injection of oxygen in the explosion chamber 10 before the explosion and discharge of air, water, purifier, and the like in the explosion chamber 10 during the operation of the disinfection after the explosion. Additionally, at the top of the explosion chamber 10 and on the side opposite, counter to the pressure of the cover 11, are provided with forced ventilation 13. Exhaust ventilation 13 is designed to bring the vessel into a state of reduced pressure or vacuum by removing air from the vessel 10 through a high pressure filter 13b using the vacuum pump 13A before the explosion and for venting exhaust air from inside the explosion chamber 10 through the filter 13C after the explosion. In addition, in the bottom of the explosion chamber 10 is formed a drain outlet 14. The drain outlet 14 is designed to release wastewater into the tank 15 processing p the following operations decontamination.

There is a flammable device (not shown)located outside the explosion chamber 10, for ignition of exploding device, such as a chemical bomb 100 enshrined in the explosion chamber 10, which provides a blasting using the remote control.

The casing 20 of the camera is a cover (building), made of steel, concrete or the like, which is made rigid enough to withstand the explosive pressure, even when exploding device, such as a chemical bomb 100, explodes with the destruction of the explosion chamber 10. The casing 20 of the camera is resistant to the pressure cap (not illustrated) and is designed for installation of exploding device, such as a chemical bomb 100, in an explosion chamber 10, when resistant to pressure the cover is open. The casing 20 of the camera also has exhaust ventilation 21 for venting exhaust air from the casing 20 of the chamber through the filter 21b, for example, containing activated charcoal, using a fan 21A.

Thus, the explosive setting is 1, which has at least one vessel 10 high pressure.

As mentioned above, the explosive setting is not limited to the outer explosive unit 1, with the vessel 10 high pressure, and can be underground explosion, which explode exploding device is istwo in the underground, tightly sealed pressure vessel or the like.

Below is a description of the blasting method of the above chemical bomb 100 in an explosion set to 1, the description of which is given above.

The transported chemical bomb 100 is placed and sealed in an explosion chamber 10 located in the casing 20 cameras explosive installation 1. Then the explosion chamber 10 is switched to the state of reduced pressure or vacuum by removing air out through the filter 13b using the vacuum pump 13A serves oxygen through the discharge inlet 12 and is closed in the blast chamber 10. The condition of reduced pressure or vacuum is a pressure of 60 mmHg (8.0 kPa) or less, preferably 50 mm Hg (6,7 kPa) or less.

As an alternative solution can be enclosed in a chamber containing an oxygen compound of an alkali metal or alkaline-earth metal as part or all of the oxygen enclosed in an explosion chamber 10. Preferred examples of oxygen-containing compounds of alkali metal or alkaline-earth metal include Na2O2(sodium peroxide) and CaO2(calcium peroxide), and the like. When you enter into oxygen-containing compound, the atoms of oxygen contained in the oxygen-containing compound of alkaline metal and alkaline-earth metal, are released and fall into the explosion chamber 10 as the oxygen required for combustion of exploding devices. Thus, the effect similar to the case when in the blast chamber 10 enter into gaseous oxygen. When injected oxygen-containing compound of an alkali metal or alkaline-earth metal, the oxygen-containing compound of an alkali metal or alkaline-earth metal are placed together with the chemical bomb 100 in the blast chamber 10 before venting the explosion chamber 10 in a state of reduced pressure or vacuum.

The number of prisoner oxygen is the amount at which the oxygen balance of the chemical bomb 100 containing an explosive substance 112 is positive before the explosion, and the pressure in the explosion chamber 10 after the explosion lower (negative) pressure outside the explosion chamber 10 (external pressure). It is preferable to keep the pressure in the explosion chamber 10 is negative, even when the pump is air, water or the like during disinfection after the explosion. In particular, the pressure gaseous oxygen when the oxygen supply is preferably from 15% to 30% of the atmospheric pressure at normal temperature.

Then blow the device explode, and the chemical bomb 100 is ignited using vosplamenyat the feeder.

The period of combustion of chemical substances during the explosion is kept long, because the oxygen balance of the chemical bomb 100 containing an explosive substance 112, remains positive during the explosion by oxygen supplied from the gas oxygen enclosed in an explosion chamber 10, or oxygen-containing compounds of alkali metal or alkaline-earth metal, a prisoner in the blast chamber 10. Additionally, the alkali metal atom in the oxygen-containing compound of an alkali metal or alkaline-earth metal, enclosed in an explosion chamber 10, binds the chlorine atom in a chemical 121 with the formation of inorganic chlorine compounds.

After the explosion pressure in the explosion chamber 10, including the pressure of the gases formed by the explosion of the chemical bomb 100 is held less than the external pressure.

After the explosion of the chemical bomb 100 explosion chamber sterilized by injection of air, water, purifier, and other components through the discharge inputs 12, the waste water away from the explosion chamber 10 into the tank 15 processing, and the exhaust air of the vessel using a ventilation explosion chamber 10 is brought out through the exhaust ventilation 13 and through the filter 13C.

The pressure in the explosion chamber 10 can be maintained less than the external pressure, even when forced air, water and other to mponent in the operation of disinfection.

Thus, in accordance with the blasting method according to this variant of execution, it is possible to convert the carbon in the shattered device to carbon dioxide or carbon monoxide and to prevent the formation of soot due to the positive oxygen balance in the blast chamber 10 containing the chemical bomb 100. Thus, it can be easier to perform disinfection of the explosion chamber 10 and to improve the efficiency of the blasting operation.

You can also extend the period of combustion of chemical substances at the time of the explosion, because the oxygen required for combustion of the explosive is fed into the explosion chamber 10. Thus, the chemical substance 121, filled in the chemical bomb 100 is oxidized, and increases the efficiency of decomposition of the chemical substance 121.

In addition, the pressure in the explosion chamber 10 is kept less than the external pressure even after the explosion. Thus, it is possible to prevent leakage of chemical substances 121 of the explosion chamber 10.

Additionally, the alkali metal atom contained in the oxygen-containing compound of an alkali metal or alkaline-earth metal, enclosed in an explosion chamber 10, is reacted with a chlorine atom in a chemical 121 with the formation of inorganic chlorine compounds. Thus, it is possible detoxification of chemical substances 121./p>
