Seeding Device Tubular Body Atomization

The invention divides the particle separation function into two distinct mechanisms: (1) a collision surface that removes large particles through direct impact, and (2) a tubular body that promotes further atomization of remaining liquid particles into smaller tracer particles. This segmentation allows simultaneous achievement of large particle removal and small particle generation, resolving the contradiction between particle size control and tracer particle quantity.

The tubular body acts as an intermediary element between the collision surface and the wind tunnel. It receives the jet flow after collision, promotes additional atomization within its structure, and then discharges the resulting small tracer particles. This intermediary structure transforms the harmful effect of the collision surface (over-removal of particles) into a beneficial outcome (generation of sufficient small tracer particles).

The invention separates the collision process from the atomization process spatially. The collision surface handles only the initial large particle removal, while the tubular body provides a dedicated zone for subsequent atomization of liquid particles near the center axis. This segmentation allows each process to optimize its function without interfering with the other, simultaneously achieving particle size control and high atomization efficiency.

The invention adds a spatial dimension to the particle processing system by introducing the tubular body as a three-dimensional structure that surrounds the jet flow path. This dimensional addition creates a controlled environment for atomization that does not interfere with the two-dimensional collision process, enabling both processes to occur simultaneously without mutual hindrance.
