Explosion-proof electric heater is a device that consumes electrical energy to convert it into thermal energy for heating the material to be heated. During operation, the low-temperature fluid medium enters its input port under pressure through the pipeline, flows along the specific heat exchange channels inside the electric heating container, and follows the path designed based on fluid thermodynamics principles, carrying away the high-temperature thermal energy generated by the electric heating elements during operation, thereby raising the temperature of the heated medium. The outlet of the electric heater obtains the high-temperature medium required by the process. 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, coking, deteriorating, or carbonizing, and in severe cases, preventing the heating element from burning out, effectively extending the service life of the electric heater.
Explosion-proof electric heater has 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 a higher temperature energy source, meeting the high-temperature heating requirements of the medium during operation.
2. This equipment has a precise structure, small volume, light weight, and convenient installation process. During heating, it does not cause harmful pollution to the surrounding environment, and can achieve relatively high heating temperature and efficiency under relatively low working pressure.
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, the 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 such as operation, high temperature, fault, and shutdown of the heater to the DCS system, and can also receive automatic and shutdown operation commands from the DCS.
5. The electrical equipment has multiple related interfaces, which can effectively monitor the temperature and flow of the heat transfer oil pump and heat transfer oil, as well as the pressure of the internal high-temperature voltage.
6. The explosion-proof electric heater can achieve more energy-saving, more environmentally friendly, and more ideal reforms.
