When high-pressure carbon dioxide is injected pressure resistant vessel 2 by supercharging device 1, as 2 internal pressure of pressure resistant vessel constantly increases,
When pressure reaches the maximum pressure of the receiving of pressure resistant vessel 2, physical explosion occurs for container partial failure, and pressure resistant vessel 2 is from groove
24 parts are cracked, and the component 3 that disperses set on container outer surface disperses outward, while explosion energy does work to air and generates punching
Hit wave.
Since 2 explosion time destructive power of pressure resistant vessel is big, to guarantee personnel and system safety, pressure resistant vessel 2, disperse component
3, the partial-length of monitoring device 7, the partial-length of input pipe 11 and efferent duct 12 is placed in explosion chamber, remaining system is located at
The outer safety zone of explosion chamber；Certainly, above system is also not necessarily limited to be arranged in explosion chamber, may also be arranged on more open space
?.
Obviously, the above embodiments are merely examples for clarifying the description, and does not limit the embodiments.It is right
For those of ordinary skill in the art, can also make on the basis of the above description it is other it is various forms of variation or
It changes.There is no necessity and possibility to exhaust all the enbodiments.And it is extended from this it is obvious variation or
It changes still within the protection scope of the invention.
