TECHNICAL FIELD

[0002] As an indispensable important equipment in chemical, pharmaceutical and food industries, reaction kettles are widely used in the mixing, reaction and evaporation of materials, and their performance and efficiency directly affect the stability and economy of the entire production process. In recent years, with the increasing demand for high-efficiency, energy-saving and environmentally friendly equipment in industrial production, reaction kettle technology has gradually developed from traditional design to automation and high efficiency. Especially under the driving of energy-saving and emission-reducing policies, more and more enterprises have begun to focus on the technical improvement of reaction kettles in heat energy utilization and material processing efficiency. Evaporation operation is one of the core links in the application of reaction kettles, and its efficiency not only determines the length of the production cycle, but also directly affects the energy consumption level and product quality.

[0003] In the evaporation operation, open reaction kettles are widely used due to their simple structure, low cost and convenient operation, especially suitable for small and medium-sized production scenes that require high flexibility and cost control. Its working principle mainly relies on the heat provided by the equipment jacket to heat the materials in the kettle to a certain temperature through heat conduction, realizing the evaporation of water or volatile components. However, the traditional open reaction kettle still has a large optimization space in terms of evaporation efficiency, especially in industrial production, as the dynamic change of the reaction kettle liquid level significantly affects the heat exchange area and heat transfer efficiency of the jacket during the continuous evaporation process. This problem of insufficient heat energy utilization is particularly prominent when the liquid level drops below the heat exchange range of the jacket, resulting in gradually weakened heat transfer capacity and reduced evaporation rate. In addition, low evaporation efficiency not only prolongs the entire production cycle, but also increases energy consumption, thereby increasing production costs, which has become one of the key pain points in the optimization of reaction kettle technology.
