It is an internationally popular high-quality long-life electric heating equipment. Used for heating, heat preservation, and temperature raising of flowing liquid and gaseous media. When the heating medium passes through the heating chamber of the electric heater under pressure, the fluid thermodynamics principle is used to uniformly take away the huge heat generated by the electric heating elements during operation, so that the temperature of the heated medium meets the user's process requirements.
2 Working Principle
The explosion-proof electric heater is a device that converts electrical energy into heat energy to heat the material to be heated. During operation, the low-temperature fluid medium enters the input port through the pipeline under pressure, and along the specific heat exchange channel inside the electric heating container, using the path designed by the fluid thermodynamics principle, it takes away the high-temperature heat energy generated by the electric heating elements during operation, so that the temperature of the heated medium rises, and 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 according to the temperature sensor signal at the outlet, so that the temperature of the medium at the outlet is uniform; when the heating element overheats, the independent overheat protection device of the heating element immediately cuts off the heating power supply, avoiding coking, deterioration, carbonization caused by overheating of the heating material, and in severe cases, burning out the heating element, effectively extending the service life of the electric heater.
Explosion-proof Principle
Explosion-proof heaters are generally used in dangerous situations where explosions may occur. Since there are various flammable and explosive oils, gases, dusts, etc. in the surrounding environment, once they come into contact with electric sparks, explosions will occur. Therefore, explosion-proof heaters need to be used for heating in such situations. The main explosion-proof measure of the explosion-proof heater is that there is an explosion-proof device in the junction box of the heater to eliminate the hidden danger of electric spark ignition. For different heating situations, the explosion-proof grade requirements of the heater are also different, depending on the specific situation.
Application Scope
Typical application occasions of explosion-proof electric heaters mainly include:
1. Heating and temperature raising of chemical materials in the chemical industry, drying of some powders under certain pressure, chemical processes and spray drying.
2. Heating of hydrocarbons, including petroleum crude oil, heavy oil, fuel oil, heat transfer oil, lubricating oil, paraffin, etc.
3. Process water, superheated steam, molten salt, nitrogen (air) gas, water gas, etc., for heating and temperature raising of fluids.
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. Application Examples
