is an electric heating device that uses heating tubes inside a cylindrical insulated container to heat gases or liquids. Meltblown fabric heaters feature fast heating speed, good thermal insulation, and high heating temperature.
1, Heater for Meltblown Equipment used in chemical industry for heating chemical materials, drying some powders under certain pressure, chemical processes, and spray drying.
2. Heating hydrocarbons, including crude oil, heavy oil, fuel oil, thermal oil, lubricating oil, paraffin, etc.
3. Heating process water, superheated steam, molten salt, nitrogen (air), 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.
Heater for Meltblown Equipment
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 positioned. The effective heating zone 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 cleaned promptly 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 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, and moisture. The lead wire should be able to withstand the temperature of the wiring part and the heating load for a long time. When tightening the wiring screws, avoid excessive force.
7. The element should be stored in a dry place. If the insulation resistance is lower than 1MΩ due to long-term storage, it 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 contaminants and moisture at the use site to prevent leakage accidents.
