The reactor is a device that realizes the reaction process, widely used in chemical, refining, metallurgy and other fields. The reactor is used to achieve a liquid phase monolithic reaction process and a liquid solution, gas-liquid, liquid solid, gas-liquid solid, and the like.
The application of the reactor begins in ancient, and the kiln manufacturing the pottery is a raw reactor. Reactors in the modern industry, such as: blast furnace and converter in metallurgical industries; fermenters and various combustors in bioengineering are different forms of reactors.
The reactor is an apparatus for realizing the reaction process, is used to achieve a liquid phase monolithic reaction process and a liquid solution, gas-liquid, liquid solid, gas-liquid solid, and the like. Stirring (mechanical stirring, airflow stirring, etc.) is often provided. When the high diameter is relatively large, the plumble can be stirred with a multilayer. When the material needs to be heated or cooled during the reaction during the reaction, the jacket can be provided at the wall of the reactor, or the heat shifting surface is provided in the device or heat exchange can also be performed by the external cycle.
Mainly refers to the operating temperature and operating pressure of the reactor. The temperature is a sensitive factor affecting the reaction process, and the appropriate operating temperature or temperature sequence must be selected to make the reaction process under optimization conditions. For example, the reversible discharge reaction should be used to take care of the reaction rate and the balance conversion.
The reactor can operate at normal pressure, pressurized or negative pressure (vacuum). The reactor of the pressurized operation is mainly used for the reaction process of gas involvement, and the operating pressure is advantageous to accelerate the gas phase reaction, and the counter-reaction rate can be improved for a total molar number, such as synthetic ammonia, synthesis methanol, and the like. Improve operating pressure can also increase the solubility of the gas in the liquid, so many gas-liquid phase reactance processes, gas-liquid solid phase reactance processes use pressurized operation to increase the reaction rate, such as xylene oxidation.
