摘要
在自行开发的装置上进行生物质热解液化试验,在试验过程中发现,贮料筒内生物质悬料架桥现象严重,无法保障连续和均匀地供料。针对该问题,在贮料筒中设置弹簧杆构件,利用一级加料螺杆的旋转推动弹簧杆在贮料筒内往复振动,从而破坏物料的悬浮架桥。试验表明,该改进方案在不增加功率消耗的前提下,解决了贮料筒内物料悬料架桥问题,保证了加料的连续性及均匀性。通过加料速度理论计算和系统改进前后的比较可知,新系统的加料速度约为改进前的2倍。
It is proved that biomass powder cannot be fed smoothly and uniformly to the fluidized bed of biomass pyrolysis and liquefaction equipment designed independently because biomass pow- der tends to hang in the air or stick on the wall of storage bin. With regards to this problem, spring steel bar component driven by the rotating of first feeding screw is set in the storage bin to ensure feeding uniformly. The experimental results show that biomass powder never hangs in the air or sticks on the wall of storage bin, the feeding is uniform and the feeding capacity doubles that of the original one even without extra power consumption.
