4. An explosion actuated pressant dispensing device as claimed in claim 3, wherein said flange is disposed coaxially with said containment body, and an outer peripheral edge of said flange is supported on an inner peripheral wall of said containment body.
5. Pressing agent scattering device based on explosive actuation according to any of claims 2 to 4, characterized in that the central tube is filled with an explosive charge that can be broken down by impacting the central tube and the cladding shell, which is provided with a detonator for detonating the explosive charge.
6. Pressing agent scattering device based on explosion actuation, as claimed in claim 5, characterized in that the fuze is fixed on one end face of the covering shell, the outer peripheral side of the fuze is covered with a protective cover made of wave-transparent material, the protective cover is of a hemispherical structure as a whole, and the fuze is located at the position of the sphere center of the protective cover.
7. The pressing agent spreading device based on explosion driving as claimed in claim 6, wherein said covering shell is equipped with a projection mechanism for projecting it, and a plurality of fins are uniformly distributed on the outer peripheral side of the end of said covering shell where said fuze is not located.
8. An explosion actuated pressant dispensing device as claimed in claim 7, wherein said outer peripheral wall of said containment body is provided with a plurality of scratches to facilitate rapid fracture of said containment body.
9. The explosion actuated pressant dispensing device of claim 8, wherein each score extends along a generatrix of said containment body and is equally spaced circumferentially along said containment body.
10. A pressing agent scattering method using the explosion-driven pressing agent scattering device according to any one of claims 1 to 9, comprising the steps of:
conveying: the coating shell is thrown to the upper space of the radioactive aerosol cloud cluster through the projection mechanism, and the fuse timely sends out a detonation signal through measuring environmental information;
detonation: the explosive is detonated by a detonation signal sent by the detonator, the explosive is instantaneously detonated to form high-temperature and high-pressure gas, so that the central tube is expanded, the pressing agent and the coating shell are extruded, the central tube and the coating shell are cracked to cause the pressing agent to leak, and the pressing agent continues to move outwards under the action of an explosive gas product formed by the explosive;
diffusion: after the action of the explosive is finished, the pressing agent forms a fog cluster under the action of explosive driving, obtains a certain speed of moving to the periphery, and starts to move to the ground under the action of the gravity of the fog cluster;
adsorption: the liquid drops in the fog cluster continuously adsorb the radioactive aerosol in the falling process, the radioactive aerosol is wrapped in the liquid drops and finally settled to the ground, and the radioactive aerosol is prevented from being continuously remained in the atmosphere.
