The broad understanding of a reaction kettle is that a container with physical or chemical reactions can achieve the heating, evaporation, cooling, and low-speed mixing functions required by the process by designing the structure and configuring the parameters of the container.

Operating conditions of reaction kettle:

Based on the purpose of the stirring process and the flow state caused by the stirrer, it is a more suitable method to determine the suitable slurry type for the process.

Reactors are widely used in petroleum, chemical, rubber, pesticides, dyes, pharmaceuticals, food, and are pressure vessels for completing processes such as vulcanization, nitrification, hydrogenation, alkylation, polymerization, and condensation, such as reactors, reaction pots, decomposition pots, polymerization pots, etc; Materials generally include carbon manganese steel, stainless steel, zirconium, nickel based (Hastelloy, Monel, Inconel) titanium, and other composite materials.

Reaction kettle usage characteristics:

The broad understanding of a reaction kettle is that a stainless steel container with physical or chemical reactions is designed and configured with parameters according to different process conditions. The design conditions, process, inspection, manufacturing, and acceptance must be based on relevant technical standards to achieve the required heating, evaporation, cooling, and low-speed mixing reaction functions of the process. Pressure vessels must comply with the standards of GB150 {Steel Pressure Vessels}, and atmospheric vessels must comply with the standards of NB/T47003.1-2009 {Steel Welded Atmospheric Vessels}. The pressure requirements during the reaction process also vary in terms of the design requirements of the container. Production must strictly follow the corresponding standards for processing, testing, and trial operation. Stainless steel reaction kettles vary according to different production processes, operating conditions, etc. The design structure and parameters of reaction kettles are different, that is, the structural style of reaction kettles is different, and they belong to non-standard container equipment.

Stainless steel reaction vessels are widely used in production users such as petroleum, chemical, rubber, pesticides, dyes, pharmaceuticals, food, and various research and experimental projects. They are containers used to complete processes such as hydrolysis, neutralization, crystallization, distillation, evaporation, storage, hydrogenation, alkylation, polymerization, condensation, hot mixing, and constant temperature reactions.

The reaction kettle is a comprehensive reaction vessel, designed based on the reaction conditions for the structure, function, and configuration accessories of the reaction kettle. From the beginning of the feed reaction discharge process, the predetermined reaction steps can be completed with a high degree of automation, and important parameters such as temperature, pressure, mechanical control (stirring, blowing, etc.), and reactant/product concentration during the reaction process can be strictly controlled.

Precautions for using the reaction pot:

The reaction kettle widely used in the chemical industry, due to the corrosiveness of the medium, sudden changes in reaction conditions, transportation, use, human factors, and other issues, always causes damage to the enamel layer in one way or another, causing production to stop. If a large area falls off, it is recommended to return to the factory for re enamel. The price of enamel kettle is relatively high, and there is no need to update the entire equipment in case of minor damage. Therefore, it is necessary to choose a suitable repair method and use (Jinsu Cheng) JS916 horse for repair. Otherwise, the reaction kettle will be corroded by the solvent in the kettle, and the damage to the enamel surface will rapidly expand, resulting in unpredictable losses such as production stoppage, accidents, and environmental pollution.

Classification and selection of reaction vessels:

According to the material, it can be divided into carbon steel reaction kettle, stainless steel reaction kettle, and glass lined reaction kettle (enamel reaction kettle).
