20090013762 | Apparatus for estimating residual life of blasting vessel, method of estimating residual life, and blasting facility - The present invention aims at estimating a residual life of a blasting vessel. For the estimation, a strain gauge | 01-15-2009 |
20090131733 | Blasting system and blasting method - The object is to rapidly clean-up an off-gas generated by blasting in a pressure vessel to such a level as to permit the exhaust of the off-gas. An object to be blasted is blasted in a pressure vessel to generate an off-gas, which is introduced into a combustion furnace to burning a combustible component contained in the off-gas. The off-gas after the burning in a reservoir section is stored in the reservoir section, and exhausted out of the reservoir section if a component contained in the off-gas complies a predetermined emission requirement, otherwise returned to at least one of the pressure vessel and the combustion furnace to be re-treated if the component does not comply the emission requirement. | 05-21-2009 |
20090165636 | Method of Cleaning Inside of Pressure Vessel for Blasting - Provided is a method of cleaning the inside of a pressure vessel for blasting to enable a short-time treatment regardless of the state of residual substances. This method includes: a step of setting an explosive for cleaning, different from an explosive for blasting, in an amount necessary for decomposing a residue of the object inside of a pressure vessel after a blasting step of setting and blasting the object and the explosive for blasting in the pressure vessel; and a step of decomposing the residue by exploding the explosive for cleaning in the pressure vessel. | 07-02-2009 |
20090260509 | Pressure Container - It is intended to provide a pressure container which can prevent dispersion of a hazardous substance or the like to the exterior and ensure a high level of safety with a simple structure. To achieve this object, a pressure container ( | 10-22-2009 |
20120017750 | BLAST TREATMENT METHOD AND BLAST TREATMENT DEVICE - Provided is a blast treatment method that enables blast treatment of a treatment subject in a sealed container to be carried out easily and safely. This blast treatment method implements: a shaped charge placement step of placing a shaped charge | 01-26-2012 |
20120017751 | BLAST TREATMENT METHOD AND BLAST TREATMENT DEVICE - A blast treatment method for blasting a treatment subject having an outer shell and a chemical agent charged into an interior of the outer shell includes the steps of: disposing an explosive to cover a periphery of the treatment subject; and detonating the explosive from respective end portions of a specific direction toward a predetermined cutting position of the treatment subject between the respective end portions so that detonation waves of the explosive advancing from respective sides of the cutting position collide in the cutting position, wherein, in the step of detonating the explosive, the chemical agent is exposed by cutting the outer shell in the cutting position through detonation of the explosive, and the chemical agent is decomposed using the detonation. | 01-26-2012 |
20120017752 | BLAST TREATMENT METHOD AND BLAST TREATMENT DEVICE - A blast treatment method enables easy and safe blast treatment of ammunition having propellant provided with a warhead having a bursting charge and a propulsion unit having a propellant. Comprised are a first explosive arrangement step of arranging a first explosive | 01-26-2012 |
20120017753 | BLAST TREATMENT METHOD AND BLAST TREATMENT DEVICE - A blast treatment method and an apparatus, which can perform the blast treatment of a treatment subject by using and securely initiating a blasting explosive having fluidity. The blast treatment method includes: a blasting preparation operation of housing a blasting explosive having fluidity in a container and placing the blasting explosive around a treatment subject as well as attaching an initiation device to the container; a housing operation of housing the container, the blasting explosive, and the treatment subject in a chamber; a decompression operation of decompressing the inside of the chamber; and a blasting operation of initiating the blasting explosive and blasting the treatment subject with the blasting explosive. In the decompression operation, the inside of the chamber is decompressed while a gas vent portion regulates the escape of the blasting explosive to the outside of the container and permits the escape of gases in the container to the outside. | 01-26-2012 |
20120031258 | BLAST TREATMENT METHOD AND BLAST TREATMENT DEVICE - A blast treatment method for blasting a treatment subject having an outer shell and a chemical agent charged into an interior of the outer shell includes the steps of: disposing an explosive on the outer side of the outer shell such that a difference occurs in a detonation pressure of the explosive, that acts on the outer shell from an outer side, between one side and another side of a predetermined cutting position of the outer shell and the outer shell is cut by a shearing force generated as a result of the difference in the detonation pressure; and detonating the explosive, wherein, in the step of detonating the explosive, the chemical agent is exposed by cutting the outer shell in the cutting position through detonation of the explosive, and the chemical agent is decomposed using the detonation. | 02-09-2012 |
