Electronic chemicals are at the forefront of the "electronic chemicals-components / parts-complete machines" industrial chain. Their process level and product quality directly and significantly affect the function and properties of components / parts, and in turn, affect the performance of end products through industrial transmission. Therefore, electronic-grade chemicals play a crucial role in the electronics industry and are of great significance for improving the performance of electronic products and promoting the development of the electronics industry. Distillation reaction equipment is required in the production of electronic-grade chemicals.

[0003] Existing distillation reactors are not suitable for heat preservation during the distillation process, resulting in some heat loss.

This reduces the energy loss of the reactor cavity, plays a role in heat preservation, and saves heating energy.

[0005] However, this distillation reactor cannot filter the liquid during feeding, cannot achieve uniform heating inside during heating, and cannot stir and clean the precipitate, thus reducing the distillation effect. Utility Model Content
