Abstract
Description
Technical Field

[0002] A reaction vessel, also known as a reaction tank or pressure vessel, is a closed container capable of heating, evaporation, cooling, and mixing through structural design and parameter configuration, and capable of completing multiphase reactions such as gas-liquid, liquid-liquid, and gas-liquid-solid reactions. It is mainly used in processes such as sulfidation, nitration, hydrogenation, hydrocarbonation, polymerization, and condensation (e.g., reactors, decomposers, polymerization kettles). This equipment is widely used in petroleum, chemical, rubber, pesticide, pharmaceutical, food, coating, and biomedical industries. Common materials include carbon manganese steel, stainless steel, zirconium, nickel-based alloys, and composite materials.
[0003] Traditional reactors require stopping the reactor and opening the lid to add materials during the reaction process. Opening the lid causes a drop in internal pressure and may produce harmful gases during the reaction. These gases are also prone to leakage during the addition process, which can affect the surrounding environment and make the reactor inconvenient to use. Summary of the Invention
