摘 要:在粘胶基碳纤维的脱胶回收过程中需要将碳纤维进行烘干加热并碾磨成粉,整个工作环境中会存在碳纤维粉尘,遇到明火容易产生爆炸,因此提出使用中频感应加热技术取代传统的明火加热对碳纤维进行烘干加热。首先计算310S不锈钢材质筒体容器加热时所需功率及电流等各项参数;根据计算所得数据选择使用COMSOL Multiphysics有限元软件对筒体容器进行加热仿真,验证将中频感应加热技术应用到粘胶基碳纤维脱胶加热工艺中的可行性与计算结果准确性;然后对电源内部谐振电容与变压器等元器件进行匹配;电源装配完成后结合实际应用进行验证。实验结果证明,中频感应加热技术可以满足对粘胶基碳纤维的烘干加热,且相较于传统加热方式,中频感应加热技术在碳纤维加热工艺中更加安全高效。In the process of degluing and recycling of viscose based carbon fiber,carbon fiber needs to be dried and heated and ground into powder,so there will be carbon fiber dust in the whole working environment,which is easy to explode when encountering open fire.Medium frequency induction heating technology is proposed to replace the traditional open fire heating for drying and heating carbon fiber.Firstly,the power and current required for heating the 310S stainless steel cylinder container are calculated.According to the calculated data,the finite element software COMSOL Multiphysics was used to simulate the heating of the cylinder container,and the feasibility and accuracy of the calculation results of applying the medium frequency induction heating technology to the heating process of viscose based carbon fiber degluing were verified.Then the internal resonant capacitance of the power supply is matched with the transformer and other components.After the power supply assembly is completed,it is verified according to the actual application.The experimental results show that the medium frequency induction heating technology can meet the drying heating of viscose carbon fiber,and compared with the traditional heating method,the medium frequency induction heating technology is more safe and efficient in the carbon fiber heating process.
