There are two forms of electric heating reactor, one is jacketed electric heating reactor, the other is zero distance electric heating reactor.
The jacketed electric heating reactor is to make the reactor into two layers. A cavity is formed between the inner cylinder and the outer cylinder. An electric heating rod is inserted into the cavity, and then a heat conducting oil is injected into the jacket. An opening is made on the upper part of the jacket to link the expansion tank. This step is very important. Because the heat conducting oil is injected into the jacket, and the jacket is sealed. The heat conducting oil absorbs heat under the action of electric heating rod. When the temperature rises, there will inevitably be a phenomenon of thermal expansion and contraction, which is equivalent to a very large force in extruding the cylinder. In this case, there will be no problem with the outer cylinder, while the inner cylinder will be extruded and deformed, resulting in the waste of the reactor. The expansion tank is arranged in the jacket for the purpose of storing the heat conducting oil from thermal expansion and cold contraction in the expansion tank to avoid extrusion of the reaction kettle. When working, the electric control cabinet controls the working intensity of the heater. It can open a group or groups of heaters or set up automatic control. The temperature range can be set through the LCD screen, so that the reactor can control the temperature by itself, start heating and stop heating by itself, so that the temperature of the reactor has been set all the time. Running within the scope. Zero-distance electric heating reactor refers to the direct welding of electric heating wire on the reactor cylinder. The temperature of this heating method is the highest, which can reach 400 degrees, but the cost is high, which is nearly twice as high as that of jacketed electric heating reactor.
