Background
The broad understanding of the reaction kettle is that the reaction kettle is a container for physical or chemical reaction, and the heating, evaporation, cooling and low-speed mixing functions required by the process are realized through the structural design and parameter configuration of the container.
The jacketed reaction kettle generally comprises a kettle body, a kettle cover, a jacket, a stirrer, a transmission device, a shaft seal device, a support and the like. The jacket is arranged outside the auxiliary kettle body. Typically, a heating liquid is provided within the jacket, which receives external heat and transfers the heat to the reactants within the kettle body.
The current oil bath heating type jacketed reaction kettle generally has two forms.
One is to set up a dedicated oil heating boiler at a place remote from the production plant. The biggest disadvantage of this form is that the heated oil must be at a high temperature at the boiler, because of heat losses during transport and high production costs.
The other is to arrange a heating resistor in the jacket of the sleeve type reaction kettle, and the most advantage of the form is to solve the above disadvantages. Then, in actual production, because the heating resistor is too close to the inner layer of the sleeve-type reaction kettle and is influenced by the high temperature of the heating resistor, the enamel layer on the inner surface of the sleeve-type reaction kettle is particularly easy to be damaged, and the sleeve-type reaction kettle is subjected to enamel surface treatment again, as well as the pipeline is time-consuming, labor-consuming and expensive, so that the production cost is greatly increased.
In summary, the heating oil of the jacketed reaction kettle has the following disadvantages during heating: the heating boiler is too far away from the sleeve type reaction kettle, and the heat loss of the heating oil in the transmission process is too large; or the heating resistor arranged in the jacket layer is too close to the enamel layer of the jacket type reaction kettle, so that the enamel layer is easily damaged.
