Working Principle:
It is a device that converts electrical energy into thermal energy to heat the required material. During operation, the low-temperature fluid medium enters the input port through a pipeline under pressure, flows along a specific heat exchange channel inside the electric heating container designed based on fluid thermodynamics, 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 obtains the high-temperature medium required by the process. The internal control system of the electric heater automatically adjusts the output power based on the temperature sensor signal at the outlet, ensuring uniform temperature of the medium at the outlet. When the heating element overheats, its independent overheat protection device immediately cuts off the heating power supply, preventing coking, deterioration, or carbonization caused by overheating of the heated material, and in severe cases, preventing damage to the heating element, effectively extending the service life of the electric heater.Meltblown Fabric Air Heater
1. Heating of chemical materials in the chemical industry, drying of certain powders under pressure, chemical processes, and spray drying.
2. Heating of hydrocarbons, including crude oil, heavy oil, fuel oil, thermal oil, lubricating oil, paraffin, etc.
3. Heating of process water, superheated steam, molten salt, nitrogen (air) gas, water gas, and other fluids that require temperature increase.
4. Due to the advanced explosion-proof structure, the equipment can be widely used in chemical, petroleum, natural gas, offshore platforms, ships, mining areas, and other places requiring explosion-proof measures.
The electric heating tube should be properly positioned and fixed, and the effective heating area must be fully immersed in liquid or solid metal; dry burning is strictly prohibited. If scale or carbon deposits are found on the tube surface, they should be promptly cleaned before reuse to avoid affecting heat dissipation and shortening service life.
3. When heating fusible metals or solid nitrates, alkalis, asphalt, paraffin, etc., first reduce the operating voltage, and only raise it to the rated voltage after the medium has melted.
4. When heating air, the elements should be arranged crosswise and evenly to ensure good heat dissipation conditions and fully heat the flowing air.
5. When heating nitrates, safety measures should be considered to prevent explosion accidents.
6. The wiring part should be placed outside the insulation layer to avoid contact with corrosive, explosive media, or moisture; the lead wires should be able to withstand the temperature of the wiring part and the heating load for a long time, and avoid excessive force when tightening the wiring screws.
