The reactor is widely used in petroleum, chemical industry, rubber, pesticide, dye, medicine and food. It is a pressure vessel used to complete the process of vulcanization, nitration, hydrogenation, alkylation, polymerization, condensation, etc., such as reactor, reactor, decomposition pot, polymerizer, etc.; generally, it is made of carbon manganese steel, stainless steel, zirconium, nickel base (Hastelloy, Monel, Inconel) alloy and other composite materials Material Science.

Reactor classification

According to the manufacturing structure of the reactor, it can be divided into three categories: open flat cover reactor, open butt welding flange reactor and closed reactor. Each structure has its application scope, advantages and disadvantages. The reactor can be divided into the following types according to its material and use:

1. Stainless steel reactor

Stainless steel reaction kettle is composed of kettle body, kettle cover, jacket, agitator, transmission device, shaft seal device, support, etc. Generally, the materials are carbon manganese steel, stainless steel, zirconium, nickel base (Hastelloy, Monel) alloy and other composite materials. According to the manufacturing structure of the reactor, it can be divided into three categories: open flat cover reactor, open butt welding flange reactor and closed reactor

The stirring forms of stainless steel reaction kettle generally include anchor type, paddle type, turbine type, propulsion type or frame type, etc. when the height diameter ratio of the stirring device is large, the multi-layer stirring paddles can be used, and the mixing device can also be optional according to the user's requirements

The different sealing types of stainless steel reaction kettle can be divided into: packing seal mechanical seal and magnetic seal. The heating methods include electric heating, hot water heating, heat transfer oil circulation heating, external (internal) coil heating, etc. the cooling methods are jacket cooling and coil cooling in the kettle

2. Glass lined reaction kettle

Glass lined reactor is a kind of composite material product, which is made by lining the glass with high silica on the inner surface of steel vessel and burning at high temperature and firmly adhering to the metal surface. Therefore, the glass lined reactor has the double advantages of glass stability and metal strength, and is an excellent corrosion-resistant equipment.

3. Magnetic stirring reactor

The static seal structure is adopted, and the magnetic coupling is used between the agitator and the motor drive. Because of its non-contact transmission torque, the static seal replaces the dynamic seal, which can completely solve the leakage problem that the mechanical seal and the packing seal cannot solve before, and make the mixing parts of the whole medium work in the absolute seal state. Therefore, it is more suitable for all kinds of inflammables and explosives , highly toxic, precious media and other chemical media with strong penetration are the most ideal non leakage reaction equipment for vulcanization, fluorination, hydrogenation, oxidation and other reactions in petroleum, chemical industry, organic synthesis, polymer material polymerization, food and other processes.
