[0002] In the current wastewater treatment field, wastewater evaporation and crystallization technology is widely used in industrial production, especially in the chemical, pharmaceutical and food processing industries. This technology mainly evaporates the solvent (usually water) in the wastewater to saturate the dissolved solid matter and then crystallize it, thereby achieving resource recovery or reducing the volume of wastewater. However, the existing wastewater evaporation and crystallization equipment has some limitations;

[0003] Publication No. "CN117509786A" discloses a high-salt wastewater evaporation crystallization system and a treatment process thereof. The high-salt wastewater evaporation crystallization system and a treatment process thereof, by fixing a scraper plate on the surface of a rotating rod, enables the crystals after the high-salt wastewater water film on the inner wall of the evaporation crystallization tank evaporates to be scraped by the rotation of the scraper plate, so that the crystals quickly fall to the bottom of the inner cavity of the evaporation crystallization tank, so that the subsequent water film can be evaporated and crystallized;

[0004] In actual use, it is not possible to adjust the operating temperature to maximize resource recovery efficiency according to the evaporation and crystallization characteristics of different substances. For example, some solid substances may need to be crystallized at lower temperatures to avoid thermal decomposition, while other substances may need to be processed at higher temperatures to increase the evaporation rate. Existing systems usually lack flexibility and cannot be adjusted to these needs. Summary of the invention
