Reactor use characteristics
The broad understanding of the reactor is a stainless steel container with physical or chemical reaction, heating, evaporation, cooling and low-speed or high-speed mixing reaction functions according to different process requirements. Pressure vessels must follow the GB150 (steel pressure vessel) standard, and atmospheric pressure vessels must follow the BN/T47003.1-2009 (steel) welding standard for atmospheric pressure vessels. Subsequently, the pressure requirements in the reaction process have different requirements for the vessel design. The production must be processed, tested and trial operated strictly accordance with the corresponding standards. Stainless steel reactors vary according to different production processes and operating conditions. The design structure and parameters of the reactor are different, that is, the structure of the reactor is different, and it belongs to non-standard container equipment.
According to the operation, it is divided into intermittent operation and continuous operation. Generally, it is a jacketed heat exchanger, but a built-in coil heat exchanger or basket heat exchanger can also be installed. It can also be equipped with an external circulation heat exchanger or a reflux condensing heat exchanger. Stirring can be used with a stirring paddle, or can be stirred with air or other inert gas bubbling. It can be used for homogeneous reaction of liquid phase, gas-liquid phase reaction, liquid-solid phase reaction, gas-solid-liquid three-phase reaction. Pay attention to controlling the reaction temperature, otherwise there will be a major accident, unless your reaction is a reaction with a small thermal effect. Intermittent operation is relatively simple, and continuous operation demands higher requirements.
What are the requirements for the use of the reactor?
According to the purpose of the mixing process and the flow state caused by the agitator, it is a more suitable method to judge the type of slurry applicable to the process. Reactors are widely used in petroleum, chemical, rubber, pesticides, dyes, medicines, and foods. They are used to complete vulcanization, nitrification, hydrogenation, alkylation, polymerization, condensation and other process pressure vessels, such as: reactors, reactors, decomposition Pots, polymerizers, etc.; materials generally include carbon-manganese steel, stainless steel, zirconium, nickel-based (Hastelloy, Monel, Inconel) alloys and other composite materials.
