Working principle and application of explosion-proof electric heater

An explosion-proof electric heater is a device used in explosion-proof situations that converts electricity into heat energy. Used for heating, insulation, and heating of flowing or stationary liquid, gaseous, and solid media.

Fluid is a type of material that consumes electrical energy and converts it into thermal energy to heat the material. In work, low-temperature fluid medium enters its input port through a pipeline under pressure, and follows a specific heat exchange channel inside the electric heating container. The path designed using fluid thermodynamics principles takes away the high-temperature thermal energy generated during the operation of the electric heating element, causing the temperature of the heated medium to rise. The outlet of the electric heater receives 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 output port, so that the medium temperature at the output port is uniform; When the heating element overheats, the independent overheating protection device of the heating element immediately cuts off the heating power supply to avoid overheating of the heating material causing coking, deterioration, and carbonization. In severe cases, it can cause the heating element to burn out, effectively extending the service life of the explosion-proof electric heater.

The explosion-proof electric heater is an efficient, energy-saving, environmentally friendly, and safe explosion-proof industrial electric heating furnace developed on the basis of advanced foreign electric heater technology. It is used for high voltage thermal energy. This type of electric heating furnace is a working method that uses electrical energy as the power source to convert its internal high-temperature voltage system into thermal energy.

Generally speaking, explosion-proof electric heating furnaces use heat transfer oil as the heat carrier, and the internal high-temperature voltage system transmits the heat of the internal high-temperature voltage to one or more electric heating equipment through the forced processing of electrical energy through the circulation pump of the heat transfer oil.

After passing through the transition function in the high-temperature voltage system of the electric heating equipment, the heat transfer oil begins to have a new heating efficiency, that is, it passes through the circulating pump again and returns to the electric heating furnace for secondary absorption of heat and transmission to the internal high-temperature voltage system of the electric heating furnace. Through this cycle of work, the electric heating furnace continuously transfers heat. Enable the internal high-temperature voltage system of the electric heating furnace to obtain sustained high-temperature energy. Thus meeting the heating requirements of the heating medium during the high-temperature process.
