What is the difference between an electrically heated reactor and other reactors?

The electric heating reaction kettle is a double-layer reaction kettle. There is a certain space between the inner tank and the outer casing. The electric heating tube is used to generate heat to transfer heat to the heat transfer oil medium, and then the heat is transferred to the reaction tank inner tank through the heat transfer oil bath. The material medium contacted by the inner tank is heated by the heat of the steel plate, and slowly reaches the temperature required for the material reaction.

The installation method of the electric heating pipe: the electric heating pipe is connected through the flange, intervenes in the oil bath of the reaction kettle interlayer, and the number and power of the electric heating pipe are combined to form the total power required, and the electric heating pipe is generally 220v/380v voltage. The 220v electric heating tube must be a group of three, star-connected to be combined into three power supply requirements (general industrial production does not use direct single-item wiring).

The 380v electric heating tube can directly connect to three 380v voltages, and the 380v electric heating tube generally has a higher single power. The number of electric heating tube of the electric heating reaction kettle is a multiple of 3, and through three groups, a plurality of groups can be synthesized according to the total root array of the required electric heating tube, and the circumferential sub-area and the sub-power are heated, and the temperature is within 300 degrees Celsius.

The far-infrared electric heating reactor is a single-layer reaction equipment. I have already introduced it before, by transferring heat to the far-infrared emitting device through the heat of the resistance wire. The far-infrared radiation directly radiates heat into the material medium through short-wave breaking, which can form no dead angle. The molecular structure of the materials in each region is uniformly heated.

The far-infrared wiring method is consistent with electric heating. However, the far-infrared device can be combined into a circumferential sub-region, upper and lower sub-region heating, and the electric heating power is linearly fine-tuned, which is achieved by adjusting the percentage of heating power, and the heating temperature is within 600 degrees (conservative).

It is not difficult to draw the following conclusions through a rough introduction of the above two heating methods.

The electric heating reaction kettle is transferred to the heat of the material through the heat transfer oil (30% is provided by the experiment), the transfer process is more complicated, and there are many intermediate links, and the far infrared is directly radiated into the reaction kettle.

This conclusion can be determined: in the case of the same heating power, the far infrared heating device has higher heat utilization rate, faster heating rate, and does not require heat transfer oil (heat transfer oil is generally required to be replaced or cleaned once a year), but The initial investment in far infrared is slightly higher.
