| 摘要 |
The invention relates to a device for dispersing particles of a pulverulent solid in a low density fluid, for example comprised between 0.5 and 1.7. It has a first housing (7) containing the pulverulent solid, a second housing (20) arranged at the vicinity of the first housing and containing the fluid, and means (5, 8, 10) which generate a pressure of approximately 1MPa to the pulverulent solid and which project it in the fluid, the volume of the first housing being smaller than the volume of the second housing. The pressure generating means are comprised of a confined pyrotechnical composition which actuate, via the generated combustion gases, a means for projection of the solid in the fluid. The first housing (7) is integral with a cylinder (4) close to its extremity adjacent to the second housing (20). The pressure generating means are integrated in the cylinder (4), the pyrotechnical composition being placed at the other cylinder extremity. Application to the intimate and rapid mixture of a solid and a liquid fluid.
