Working principle and structure composition of jacketed reactor
- May 09, 2018 -

Due to the excellent performance of the jacketed reactor itself, the scope of its use continues to expand as it continues to evolve. At present, the jacketed reactor with stirring function has become one of the commonly used reaction equipment in the industries of fine chemicals, coatings, hot melt adhesives, medicine and food. Below to understand some related content.


First, the outer jacket reaction kettle working principle:

Based on practical application and work characteristics, the external jacket reactor used by us during normal production mainly requires that a certain volume of two or more liquids be used through a stirrer under certain pressure and temperature conditions. Mixing liquid with solid or gaseous material to promote its reaction. The jacket on the kettle body is mainly a module for heating and cooling.


Second, the outer jacket reactor structure composition:

From the structural point of view, the main components included in a set of jacketed reactors are: agitation vessels (including tanks and jackets), agitation devices, transmissions, shaft seals, bearings, manholes, and processes. Take over and other accessories. Most of them belong to medium and low pressure vessels. The stirring device consists of an agitator and a stirring shaft. The agitating form is usually determined by the process design, and includes an anchor type, a paddle type, a worm gear type, a push type or a frame type.


At the same time, in the production process, it is also inseparable from the help and support of the transmission device. The transmission device is mainly set to drive the stirring device, and is mainly composed of a motor, a speed reducer, a coupling, and a transmission shaft. In order to better meet the user's requirements for use, the number of openings, specifications, or other requirements for external jacketed reactors can usually be designed and manufactured according to customer requirements.


In today's market, due to different work requirements, the heating mode used in the jacketed reactor is also varied, including: heating rod heating, steam heating, heat transfer oil circulation heating reactor. One type of electric heating type jacketed reactor consists of an electric heating rod to heat the thermal oil, and a thermal oil as the medium to transfer the materials in the kettle.
