| 本文就废橡胶中是否含有钢丝对微波裂解过程的影响进行了有限元仿真和实验探究。仿真结果表明含有钢丝的废橡胶在钢丝附近场强明显增强,热点增多且分布均匀。利用自制的废橡胶微波裂解实验炉进行的裂解实验也表明,废橡胶中适量的钢丝存在会促进废橡胶的裂解,使裂解升温更快,出油比例更高。由此认为,废轮胎的整胎微波裂解更有利于提高裂解效率、促进节能环保和改善裂解产物品质。 |
| 英文摘要: |
| Finite element simulation and experiment research are carried out for the influence of whether there are steel cords within waste rubber on the microwave pyrolysis process in this paper. The simulation results show that the electromagnetic field strength of waste rubber with steel cords is obviously enhanced near the cords, the hot spots increase and distribute evenly. Pyrolysis experiments are made using a home-made microwave pyrolysis experimental furnace for waste rubber. The experimental results show that the presence of a moderate amount of steel cords in the waste rubber promotes the pyrolysis of waste rubber, which makes the pyrolysis temperature rise faster and oil out proportion higher. It is considered that microwave pyrolysis of whole waste tire is more conducive to raise the pyrolysis efficiency , promote energy saving and environmental protection, and improve the quality of pyrolysis products. |
