Reactor _ Stainless Steel Reactor _ Electric Heating Reactor

1、 Overview of Reactor

A reaction vessel is a container used to complete physical or chemical reaction processes. It is a container designed to meet the temperature, pressure, speed, liquid level, and other requirements of the reaction process by designing the structure and configuration of the reaction vessel. The reaction kettle has functions of heating, cooling, dispersing, shearing, and mixing at low and high speeds. Reaction vessels are widely used in petroleum, chemical, rubber, pesticide, dye, pharmaceutical, and food industries to complete processes such as vulcanization, nitration, hydrogenation, alkylation, polymerization, and condensation. Therefore, reaction vessels are also called reactors, reaction pots, reaction tanks, decomposition pots, polymerization pots, condensation pots, distillation pots, etc. They are used in different reaction processes and have different names. This type of tank is commonly referred to as a reaction vessel. A reaction vessel is a comprehensive reaction vessel, and its structure, function, and configuration accessories are designed according to the reaction conditions. The reaction kettle can achieve a high degree of automation in completing pre-set reaction steps from the beginning of the feed reaction discharge process, and strictly regulate important parameters such as temperature, pressure, mechanical control (stirring, blowing, etc.), and reactant/product concentration during the reaction process. The structure of a reaction kettle generally consists of a kettle body, transmission device, stirring device, heating device, cooling device, sealing device, cleaning device, etc. Corresponding auxiliary equipment: fractionation column, condenser, water separator, collection tank, filter, etc.

2、 The main purpose of a reaction kettle

Widely used in petroleum, chemical, rubber, pesticide, dye, medicine, food, pressure vessels for completing processes such as vulcanization, nitration, hydrogenation, alkylation, polymerization, and condensation.

3、 Classification of Reactor Materials

The materials of reaction vessels generally include carbon manganese steel, stainless steel, zirconium, nickel based (Hastelloy, Monel) alloys, and other composite materials. The reaction vessels produced by our company are mainly made of stainless steel materials such as SUS304 and SUS316L. Blenders come in anchor, frame, paddle, turbine, scraper, and combination types. The rotating mechanism can use cycloidal pinwheel reducers, continuously variable speed reducers, or variable frequency speed reducers to meet the special reaction requirements of various materials. The sealing device can adopt sealing structures such as mechanical seals and packing seals. Heating and cooling can be achieved through structures such as jackets, half tubes, coils, and Miller plates. Heating methods include steam, electric heating, and thermal oil to meet the process requirements of different working environments such as acid resistance, high temperature resistance, wear resistance, and corrosion resistance. And it can be designed and manufactured according to the user's process requirements.
