The scope and structure of the jacketed reactor vessel
- Apr 13, 2018 -

Whether it is the field of fine chemicals, coatings, pharmaceuticals and food processing industries, the external jacketed reactor vessel with stirring is one of the commonly used reaction equipment in production. The so-called jacketed reactor is a kind of reactor, which is based on a certain pressure and temperature conditions, with a stirrer to a certain volume of two or more liquids and liquids and solid or gas materials are mixed to promote it Reaction equipment.


In general, during the reaction of materials, the jacket above the outer jacket reactor kettle is mainly used for heating and cooling modules. The equipment is mainly composed of a stirring vessel (including a tank body and a jacket), a stirring device, a transmission device, a shaft sealing device, a support, a manhole, a process takeover, and some accessories. Mostly low pressure vessels.


The stirrer in the jacketed reactor vessel also plays an important role, and because of different process requirements, the type of agitation used is also different. More common anchor, slurry, worm gear, push or box and so on. The transmission device is arranged to drive the stirring device, which is mainly composed of a motor, a speed reducer, a coupling, and a transmission shaft.


Under normal circumstances, depending on the actual requirements of the user, it is necessary to determine the number of holes and specifications of the jacketed reactor based on these comprehensive factors. Generally classified according to jacket heating, divided into: heating rod heating, steam heating, heating oil circulation heating reactor. Among them, the electric heating reactor heats the heat transfer oil through the electric heating rod, and uses the heat transfer oil as the medium to transfer heat to the material in the kettle.


At present, in the process of designing the overall structure of the jacketed reactor, it is generally necessary to consider the process requirements, and to determine the structural form of each part of the jacketed reactor, such as the header form, in combination with the requirements for installation and maintenance. Heat transfer surface, transmission type, shaft seal, and various accessories.
