[0002] At present, in the silicon wafer cutting process in the solar energy field, solar-grade battery silicon wafers are cut from silicon blocks or silicon rods by a multi-wire cutting machine. According to the current development trend of the industry, diamond wire multi-wire cutting technology will become the mainstream of multi-wire cutting in the future. However, in the diamond wire cutting process of monocrystalline silicon or polycrystalline silicon, the silicon powder generated when the diamond wire cuts the silicon rod is deposited into the cutting slurry together with other impurities to form silicon mud. The silicon mud is mainly composed of silicon dioxide and hydrates, contains a certain amount of silicon elements, and may also contain some harmful substances such as heavy metals and organic matter. The silicon mud has a high water content and complex composition, and requires multiple processes for high-temperature treatment to achieve a drying effect.
