is an electric heating device that installs heating tubes inside a cylindrical insulated container to heat gases and liquids. The melt-blown fabric heater features fast heating speed, good insulation performance, and high heating temperature.
1, Melt-blown Equipment Special Heater for chemical industry: heating and raising temperature of chemical materials, drying certain powders under pressure, chemical processes, and spray drying.
2. Heating hydrocarbons, including crude oil, heavy oil, fuel oil, heat transfer oil, lubricating oil, paraffin, etc.
3. Heating process water, superheated steam, molten salt, nitrogen (air) gas, water gas, and other fluids that need 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.
Melt-blown Equipment Special Heater
Precautions:
1. The element is allowed to work under the following conditions:
A. The relative humidity of air is not more than 95%, and there is no explosive or corrosive gas. Except for explosion-proof heaters
B. The 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 positioned and fixed. 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 before reuse 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 allow the flowing air to be fully heated.
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 wires 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 drops below 1MΩ due to long-term storage, it can be dried in an oven at about 200°C or heated with reduced 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 in the usage environment to prevent leakage accidents.
