Explosion-proof electric heater is a device that converts electrical energy into thermal energy to heat the materials that need to be heated. During operation, the low-temperature fluid medium enters its input port under pressure through the pipeline, follows the specific heat exchange flow path inside the electric heating container, and utilizes the path designed based on fluid thermodynamics principles to carry away the high-temperature thermal energy generated by the electric heating elements during operation, thereby raising the temperature of the heated medium. At the outlet of the electric heater, the high-temperature medium required by the process is obtained. The internal control system of the electric heater automatically adjusts the output power of the electric heater based on the temperature sensor signal at the outlet, ensuring uniform temperature of the medium at the outlet. When the heating element overheats, the independent overheat protection device of the heating element immediately cuts off the heating power supply, preventing the heated material from overheating, which could cause coking, deterioration, or carbonization, and in severe cases, burning out the heating element, effectively extending the service life of the electric heater.
Explosion-proof electric heaters have the following characteristics in the mechanical electric heating industry:
1. It can achieve uninterrupted transmission of the internal high-temperature voltage system, ensuring that the internal high-temperature voltage system of the electric heating equipment uses electrical energy to obtain higher-temperature energy, meeting the high-temperature heating requirements of the medium during operation.
2. This type of equipment has a precise structure, lightweight volume, light weight, and is easy to install. During heating, it does not cause harmful pollution to the surrounding environment, and can achieve quite high heating temperatures and efficiency at relatively low working pressures.
3. High level of intelligence. By setting the original temperature during operation through the high-temperature voltage medium inside the gas electric heater, in experiments, this temperature control accuracy can reach a range of ±2℃ to ±0.2℃.
4. The internal high-pressure system of the equipment can provide alarm signals to the DCS system, such as heater running, high temperature, fault, and shutdown, and can also accept automatic and shutdown operation commands from the DCS.
5. The electrical equipment has multiple related interfaces, allowing effective monitoring of the heat transfer oil pump, the temperature and flow rate of the heat transfer oil, and the pressure of the internal high-temperature voltage.
6. Explosion-proof electric heaters can achieve more energy-saving, more environmentally friendly, and more ideal reforms.
