Description

TECHNICAL FIELD

[0002] The filter assembly plays a crucial role in the insulating oil reaction kettle. Here is a specific elaboration of its role: first, the main function of the filter assembly is to filter out impurities and residues generated during the reaction. In the insulating oil reaction kettle, various chemical raw materials react under specific temperature and pressure, and some solid particles, unreacted raw materials or other impurities may be generated during these reactions. The filter assembly can ensure that these impurities do not flow out with the reaction product, thereby ensuring the purity and quality of the product. Secondly, the filter assembly helps to improve the working efficiency of the reaction kettle. Through the filter assembly, the reaction product can directly flow out from the bottom of the reaction kettle without additional separation and purification steps. This greatly simplifies the operation process, reduces reaction time and production cost. In addition, the filter assembly also helps to protect the reaction kettle itself. During the reaction process, if impurities and residues accumulate inside the reaction kettle, it may cause corrosion or blockage of the equipment, leading to equipment failure or reduced reaction efficiency. By regularly cleaning or replacing the filter assembly, this situation can be effectively prevented, prolonging the service life of the reaction kettle.
