Meltblown Fabric Heater

It is a device that converts electrical energy into thermal energy to heat the material to be heated. During operation, the low-temperature fluid medium enters the input port through the pipeline under pressure, flows along the specific heat exchange channel inside the electric heating container, and follows the path designed based on fluid thermodynamics principles, taking away the high-temperature thermal energy generated by the electric heating elements during operation, thereby raising the temperature of the heated medium. 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 based on the temperature sensor signal at the outlet, ensuring uniform temperature of the medium at the outlet. When the heating element overheats, the independent overheat protection device of the heating element immediately cuts off the heating power supply, preventing the heated material from overheating, coking, deteriorating, or carbonizing, and in severe cases, preventing the heating element from burning out, effectively extending the service life of the electric heater.

Application Scenarios:

1. Heating and raising temperature of chemical materials in the chemical industry, drying of certain powders under certain pressure, chemical processes, and spray drying.
2. Heating of hydrocarbons, including crude oil, heavy oil, fuel oil, heat transfer oil, lubricating oil, paraffin, etc.
3. Heating of process water, superheated steam, molten salt, nitrogen (air), water gas, and other fluids that require heating.
4. Due to the adoption of advanced explosion-proof structures, the equipment can be widely used in chemical, petroleum, natural gas, offshore platforms, ships, mining areas, and other places requiring explosion-proof measures.

Precautions:

1. The element is allowed to work under the following conditions:
A. Relative humidity of air not greater than 95%, no explosive or corrosive gases. (Except for explosion-proof heaters)
B. Working voltage should not exceed 1.1 times the rated value, and the shell should be effectively grounded.
C. Insulation resistance ≥1MΩ; Dielectric strength: 2KV/1min.
2. The electric heating tube should be properly fixed, and the effective heating area must be completely 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 cleaned promptly to avoid affecting heat dissipation and shortening service life.
3. When heating fusible metals or solid nitrates, alkalis, asphalt, paraffin, etc., the operating voltage should be reduced first, and only after the medium melts can it be raised to the rated voltage.
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; avoid excessive force when tightening the wiring screws.
7. The elements should be stored in a dry place. If the insulation resistance is lower than 1MΩ due to long-term storage, they can be dried in an oven at about 200°C, or heated by reducing voltage until the insulation resistance is restored.
8. The magnesium oxide powder at the outlet end of the electric heating tube should be protected from pollutants and moisture infiltration at the use site to prevent leakage accidents.
