Introduction to Explosion-Proof Electric Heating Rod

Dari Electric recommends for you

Explosion-proof stainless steel electric heating tube is a device that converts electrical energy into heat energy to heat the required material. Explosion-proof heating tube consists of outer shell (stainless steel/carbon steel/copper/titanium, etc.), heating wire (nickel-chromium-lead alloy), filler (magnesium oxide, used for heat conduction and insulation), outer shell (stainless steel, carbon steel, titanium, copper, etc.), ceramic seal (function: insulation), and explosion-proof box. During operation, the low-temperature fluid medium enters the input port under pressure through the pipeline, flows along the specific heat exchange channel inside the electric heating container, following the path designed based on the fluid thermodynamics principle of the air electric heating tube, and takes away the high-temperature thermal energy generated by the electric heating elements in the air heating tube during operation, so that the temperature of the heated medium in the air heating tube rises, and the outlet of the heating tube obtains the high-temperature medium required by the process. The internal control system of the heating tube automatically adjusts the output power of the electric heating tube based on the temperature sensor signal at the output port, making the medium temperature at the output port of the air heating tube uniform; when the heating element of the air heating tube overheats, the independent overheat protection device of the heating element immediately cuts off the heating power supply, preventing the heated material in the air electric heating tube from overheating, coking, deteriorating, or carbonizing, and in severe cases, preventing the heating element in the air electric heating tube from burning out, effectively extending the service life of the electric heating tube. The explosion-proof heating tube is also an internationally popular high-quality long-life electric heating device. The air heating tube is used for heating, maintaining temperature, and warming flowing liquid and gaseous media. When the heating medium in the air electric heating tube passes through the electric heater heating chamber under pressure, it uniformly takes away the huge heat generated by the electric heating elements in the air heating tube using fluid thermodynamics principles, so that the temperature of the heated medium in the air electric heating tube reaches the user's process requirements.

Typical application occasions of explosion-proof electric heating tube mainly include

1. Heating of chemical materials in the chemical industry, drying of some powders under certain 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) gas, water gas, etc., for heating fluids that need temperature rise.

Due to the use of 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.
