Description

Technical Field

[0001] This utility model relates to the field of polycrystalline silicon processing technology, and in particular to a water quenching system for packaging polycrystalline silicon crushed material to prevent moisture residue. Background Technology

[0002] Polycrystalline silicon is a polycrystalline material composed of many small crystals; it is a form of elemental silicon. Under supercooled conditions, when molten elemental silicon solidifies, silicon atoms arrange themselves into numerous crystal nuclei in a diamond lattice. These nuclei grow into grains with different crystal orientations, which combine to form polycrystalline silicon. Polycrystalline silicon is widely used in photovoltaics, integrated circuits, and other fields, and is a crucial basic material for the photovoltaic and electronics industries.

[0003] Water quenching is used in the polycrystalline silicon production process to reduce the breakage loss rate of polycrystalline silicon material. By rapidly cooling the silicon rod after high-temperature calcination, cracks are formed in the rod. This reduces the generation of dust and particles during subsequent crushing, thereby lowering the breakage loss rate. After water quenching, the silicon material breakage loss can be significantly reduced from 3.5% to about 2% after being crushed in the same crusher.

[0004] Residual moisture can degrade material performance, causing short circuits or corrosion in electronic devices, or affecting photoelectric conversion efficiency in solar panels. Therefore, ensuring the surface and interior of polycrystalline silicon materials are dry before packaging is crucial. Utility Model Content
