Explosion-proof Electric Heater is a device that converts electrical energy into thermal energy to heat the required materials. During operation, the low-temperature fluid medium enters the input port through the pipeline under pressure, flows along the specific heat exchange channel inside the electric heating container, following the path designed based on fluid thermodynamics principles, and carries 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 and causing coking, deterioration, or carbonization, which could otherwise damage the heating element in severe cases, effectively extending the service life of the electric heater.
Application Scope
Typical application scenarios mainly include:
1. Heating and temperature raising of chemical materials in the chemical industry, drying of certain powders under specific pressure, chemical processes, and spray drying.
2. Heating of hydrocarbons, including crude oil, heavy oil, fuel oil, thermal oil, lubricating oil, paraffin, etc.
3. Process water, superheated steam, molten salt, nitrogen (air), water gas, and other fluids requiring heating and temperature raising.
4. Due to the advanced explosion-proof structure, the equipment can be widely used in chemical, military, petroleum, natural gas, offshore platforms, ships, mining areas, and other places requiring explosion-proof measures.
