Far Infrared Electric Heater is a new generation of heating equipment for reactors, featuring reasonable structural design, good radiation effect, safety and reliability, significant energy saving, long service life, no noise, no pollution, no additional space occupation, precise temperature control, and easy installation and operation.
Application:
It saves more than 30% of production costs compared to traditional heat transfer oil and steam heating. In the context of energy conservation, emission reduction, and environmental protection, many large chemical units at home and abroad are replacing heat transfer oil and steam heating with far infrared heating. The product is widely used in industries such as automotive, textile, printing and dyeing, dye, papermaking, bicycle, refrigerator, washing machine, chemical fiber, ceramics, electrostatic spraying, grain, food, pharmaceutical, chemical, tobacco, etc., achieving ultra-fast drying and heating purposes, especially suitable for chemical reactors, large drying rooms for leather machinery, drying ovens, and conveyor drying tunnels.
Principle:
The far infrared electric heater uses electric heating combined with far infrared technology to evenly distribute heat into the reactor. It is a radiant heater, and far infrared has the effect of promoting blood circulation, which is beneficial and harmless to the human body.
The silicon carbide far infrared radiation element is the main component of this heater. Silicon carbide has a room temperature flexural strength of 45MPa, a high temperature flexural strength of 50MPa at 1000°C, a bulk density of 2.7-2.75g/cm³, a thermal expansion rate of 0.42-0.48% at 900°C, and a thermal conductivity of 10.3-16.7W/m·K (at 350°C).
After being powered on, the far infrared heater can form a strong broad-spectrum directional radiation in the vertical space, effectively converting electrical energy into far infrared radiation energy, which is directly transferred to the material to be dried, quickly converted into molecular thermal motion, drying from the inside out, achieving rapid drying and setting, and achieving significant energy-saving effects. When far infrared radiation hits an object, it can be absorbed, reflected, or transmitted. The heated and dried material absorbs far infrared radiation energy at a certain depth inside and on the surface molecules simultaneously, generating a self-heating effect, causing the solvent or water molecules to evaporate, with uniform heating, thus avoiding deformation and quality changes caused by different thermal expansion, maintaining the appearance, physical and mechanical properties, fastness, and color of the material.
