According to the principle of action in the production process, pressure vessels are divided into reaction pressure vessels, heat exchange pressure vessels, separation pressure vessels, and storage pressure vessels. The specific division is as follows:
Heat exchange pressure vessel (code E): It is mainly used to complete the heat exchange of the medium, such as shell and tube heat recovery boiler, heat exchanger, cooler, condenser, heater, sterilizer, dyeer, drying cylinder, steaming wok, preheating pot, solvent preheater, steamer, evaporator, electric steam generator, gas generator water jacket, etc.
