Exploring Pressure Vessels: Understanding the Functioning Principles of Different Types
Pressure vessels are indispensable equipment in industrial production, widely used in fields such as chemical engineering, energy, and pharmaceuticals. To better understand and manage these vessels, they can be categorized based on their operational principles in the production process. The main types include reaction pressure vessels, heat exchange pressure vessels, separation pressure vessels, and storage pressure vessels. The specific classifications are as follows:
Reaction pressure vessels, designated as "R," are primarily used to facilitate physical or chemical reactions of the medium. This category includes various reactors, reaction kettles, polymerization reactors, synthesis towers, reformers, and gasifiers. These vessels play a critical role in industries such as chemical engineering and pharmaceuticals, enabling materials to undergo transformations under specific conditions.
Heat exchange pressure vessels, designated as "E," are used to achieve heat transfer between mediums. These include various heat exchangers, coolers, condensers, and evaporators. These vessels enable efficient energy transfer during processes, thereby enhancing production efficiency.

Separation pressure vessels, designated as "S," are used for balancing fluid pressure and purifying and separating gases. This category includes separators, filters, oil collectors, absorption towers, copper wash towers, drying towers, stripping towers, steam drums, and deoxygenators. These vessels play a crucial role in maintaining the stability of fluid systems and purifying gases.
Storage pressure vessels, designated as "C," and spherical tanks, designated as "B," are primarily used for storing and containing gases, liquids, or liquefied gases. This category includes various storage tanks, buffer tanks, sterilization pots, dyeing machines, drying cylinders, and steam boilers. These vessels are critical in energy storage, transportation, and other sectors.
Classifying pressure vessels based on their functional principles aids in the better design, manufacturing, and use of these essential pieces of equipment. Each type of pressure vessel has unique applications across industries, collectively forming a vital part of the modern industrial system.
