Problems solved by technology
[0002] At present, the equipment used for protective atmosphere roasting is mainly rotary kiln, tunnel kiln and vacuum furnace, but when the rotary kiln and tunnel kiln use relatively low-cost coal, gas or other fuels, the fuel heating airflow must be in contact with the roasting or distillation materials. It will inevitably cause the evaporation of roasted or distilled materials or the reaction of volatiles with oxygen and carbon in the heated air stream, so the range of use of rotary kilns and tunnel kilns is limited
In addition, the rotary kiln consumes a lot of power and heat energy due to the need for power and poor heat preservation; for some processes that require the use of rotary kiln balls for pellet roasting, on the one hand, the rotary kiln needs to continuously throw down the roasted materials, resulting in some pellets Broken, which affects the process indicators; on the other hand, due to the small unit production capacity of the rotary kiln, the investment in the roasting equipment of the factory is huge
Although the vacuum furnace can achieve protective atmosphere roasting, there are problems of continuous production and high energy consumption

Background technique [0002] At present, the equipment used for protective atmosphere roasting is mainly rotary kiln, tunnel kiln and vacuum furnace, but when the rotary kiln and tunnel kiln use relatively low-cost coal, gas or other fuels, the fuel heating airflow must be in contact with the roasting or distillation materials. It will inevitably cause the evaporation of roasted or distilled materials or the reaction of volatiles with oxygen and carbon in the heated air stream. Therefore, the scope of use of rotary kilns and tunnel kilns is limited. In addition, the rotary kiln consumes a lot of power and heat energy due to the need for power and poor heat preservation; for some processes that require the use of rotary kiln balls for pellet roasting, on the one hand, the rotary kiln needs to...
