Structure design and function of stainless steel reactor

Stainless steel reactor is used in food, biochemical industry and other industries. Because the design of the reactor depends on the use and operation, the production must meet the requirements and specifications.
The overall structure of stirred tank usually consists of the following five parts:
1. Kettle body
The reactor body is the space for chemical reaction of materials, which is composed of cylinder body and upper and lower heads. It is usually closed, sometimes open type, depending on the reaction medium.
2. Heat transfer device
A heat transfer device for heating or cooling is arranged inside or outside the reactor body, which is usually the external jacket or snake tube inside the reactor body.
3. Mixing device of reactor
In order to make the material mix evenly and contact well, it is necessary to set up a stirring device in the kettle. The mixing device is composed of mixing shaft and agitator. The rotation of the motor is reduced to the appropriate speed by the reducer, and then driven by the coupling. The vertical mixing shaft is cantilever. If necessary, intermediate bearing or bottom bearing can be set in the reactor.
4. Shaft seal device
Since the mixing shaft is dynamic and the head of the kettle body is static, a seal (shaft seal) should be applied at the extension of the mixing shaft. The role of the shaft seal is to maintain the pressure (or vacuum) in the equipment, so as to prevent reaction materials from escaping and impurities from penetrating. The shaft seal usually adopts packing seal or mechanical seal.
5. Other structures of reactor
It mainly includes manhole, handhole, connecting pipe, thermometer, pressure gauge, sight glass, relief device, etc.
