Application and working principle of explosion-proof electric heater
Explosion-proof electric heater is a kind of equipment that converts electricity into heat energy for explosion-proof applications. It is used to heat, heat, and heat liquid or gas, solid, or stationary media.
The typical applications of explosion-proof electric heaters mainly include :
1. The chemicals in the chemical industry are heated and heated, some powders are dried under certain pressure, chemical processes and spray drying.
2. Hydrocarbon heating, including petroleum crude oil, heavy oil, fuel oil, thermal oil, lubricating oil, paraffin wax, etc. 3. Process water, superheated steam, molten salt, nitrogen (air) gas, water gas, etc. need to be heated and heated. The fluid warms up.
4, due to the use of advanced explosion-proof structure, equipment can be widely used in chemical, military, oil, natural gas, offshore platforms, ships, mining areas and other places that require explosion protection.
working principle
Explosion-proof electric heater is a kind of energy conversion to heat energy, to heat the material to be heated. In the work, the low-temperature fluid medium enters the input port through the pipeline under pressure, follows the specific heat exchange flow path inside the electric heating container, uses the fluid thermodynamic principle to design the path, and takes away the high-temperature thermal energy generated during the operation of the heating element. The temperature of the heated medium is increased, and the electric heater outlet is subjected to 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 according to the temperature sensor signal of the output port to make the medium temperature of the output port uniform; when the heating element is overheated, the independent overheat protection device of the heating element immediately cuts off the heating power to avoid Overheating of the heating material causes coking, deterioration, and carbonization. In severe cases, the heating element burns out and the service life of the electric heater is effectively prolonged.
