Electromagnetic induction heating reaction kettle

Abstract

The present invention discloses an electromagnetic induction heating reaction kettle, which comprises a kettle body for placing a material, a stirring device arranged inside the kettle body and used for stirring the material, and a bracket connected to the bottom portion of the kettle body and used for supporting the kettle body, wherein the kettle body comprises a kettle body bottom housing and a kettle body upper housing arranged on the kettle body bottom housing, the electromagnetic induction heating reaction kettle further comprises an electromagnetic induction heating coil connected to a high-frequency power supply, and the electromagnetic induction heating coil is suspended below the kettle body bottom housing and is electrically insulated from the kettle body bottom housing so as to heat the kettle body bottom housing. According to the present invention, the electromagnetic induction heating technology is utilized, and the electromagnetic induction heating coil is arranged on the bottom portion of the kettle body and is adopted as the heating source to replace the steam supply of the boiler room, such that the thermal efficiency is high, the power adjustment range is large, the heating temperature can achieve 250 DEG C, no steam condensed water participates in the material, and the good effects of high efficiency, strong controllability and no pollutant introduction are achieved.

Description

technical field [0001] The invention relates to the technical field of heating equipment, in particular to an electromagnetic induction heating reactor. Background technique [0002] Reactor is a pressure vessel widely used in petroleum, chemical, rubber, pesticide, dye, medicine, food and other fields to complete vulcanization, nitration, hydrogenation, alkylation, polymerization, condensation and other processes. The existing reaction kettle is mainly composed of the bottom shell of the kettle body, the upper shell of the kettle body, the jacket, the stirring device and the support, etc., and the heating methods are mostly as follows: steam from the boiler room is used as the heating source, and coils, pipes, etc. are used directly or indirectly. Jacket, etc. for heating. Although the above method can achieve the basic heating function required by the reactor, the heating method has the following defects: the system is inert, the reaction is slow, and the efficiency is lo...

Problems solved by technology

Although the above method can achieve the basic heating function required by the reactor, the heating method has the following defects: the system is inert, the reaction is slow, and the efficiency is low; the maximum heating temperature is usually below 120 ° C, and the temperature is not easy to control; Condensed water is mixed into the material, causing pollution to the material

[0003] In order to increase the heating speed, some manufacturers insert electric heating tubes inside the reactor. Although this method can improve the heating efficiency, the electric heating tube has a short life, low power, and is easy to scale. It also affects the stirring, loading and unloading of materials inside the reactor. , bringing many disadvantages
