Problems solved by technology

It can be seen that the high-infrared quartz heating tube has the characteristics of fast heating time, but due to the small radiation surface area of ​​the quartz heating tube, the energy attenuation is large, the metal material of the reflective screen is easily oxidized, the reflection effect is poor, and it is difficult to match and adjust the dry absorption wavelength of the object. The continuous working life of the infrared quartz heating tube is not more than 5000 hours, and the operating cost is relatively high

Description

technical field [0001] The invention relates to an infrared radiation heating device, in particular to a high-energy full-band infrared radiation heater. Background technique [0002] As we all know, infrared radiation can be divided into three bands according to its radiation wavelength. The near-infrared band has a wavelength of 0.75-2.5 μm, a radiator temperature of 2000-2200 °C, a heating element startup time of 1-2 seconds, and a bright color of the radiation source. The wavelength of the mid-infrared band is 2.5-4μm, the temperature of the radiator is 800-900°C, the start-up time of the heating element is 60-90 seconds, and the radiation source is dark red; the wavelength of the far-infrared band is 4-50μm, and the temperature of the radiator is 400 ~600°C, the start-up time of the thermal element is 15 minutes, and the radiation source is dark. Infrared radiation heaters used in industry have different wavelengths of heating and absorption of infrared radiation for d...
