Outer coil heating reactor structure and advantages
- Apr 11, 2018 -

Regarding the structural composition of the Outer coil heating reactor, the equipment is mainly composed of a kettle body, a kettle cover, a jacket, a stirrer, a transmission device, a shaft seal device, and a support. External coil reactors are generally made of materials such as carbon-manganese steel, stainless steel, zirconium, nickel-base (Hall, monel) alloys, and other composite materials.


At the same time, due to different production processes and operating conditions, the structure of the outer coil reactor is also different. At present, the device has been widely used in petroleum, chemical, rubber, pesticides, dyes, medicine and food, mainly for the completion of vulcanization, hydrogenation, hydrocarbonation, polymerization, condensation and so on.


What are the main advantages of the outer coil reactor? Compared with other similar products, first of all, it can withstand greater pressure, and can reduce the thickness of the internal cylinder body, the internal cylinder is divided into partial external pressure by the semi-circular tube.


Not only that, due to the special design of the structure, the semicircular tube jacket of the outer coil reactor allows the inner cylinder to be divided into partial external pressure by the semicircular tube. The outer coil tube jacket can also prevent the inner cylinder from becoming unstable. . Therefore, from the analysis of its overall structure, each outer coil jacket has become a reinforcement ring of the reaction vessel body, replacing the inner sleeve body, which is generally subjected to the internal pressure. Usually, the outer coil tube jacket has strong pressure resistance. , can reach between 0.6 and 2.5MPa.


In this way, during the material reaction process, the quality of the heat transfer medium can be significantly improved. For example, in the use of steam heat transfer, the use of external coil reactors often control the steam pressure to 0.4 MPa. The use of an external coil jacketed reactor, the steam pressure can be 0.7 to 1.3 MPa, without decompression. In addition, the outer coil reactor greatly improves the inner cylinder's stress state, so the inner cylinder wall thickness is relatively thin.
