摘要
餐厨垃圾预处理阶段物质分选对整个处理工艺影响较大,分选不到位,浆料中杂质就多,导致设备故障率高、管路磨损大等问题。通过降低大物质分选机转速及进料频率对餐厨垃圾预处理系统中的分选单元进行试验研究。结果表明:随着转速的降低,可以达到分选出大块玻璃、陶瓷的效果。随着大物质分选机转速的降低,分选料含水率有所增加但不明显,含油率会有所增高,且存在将部分有机质分离出来等问题,但并未出现大量浆料被分选出的现象。随着进料频率增加,分选料含量随之增加。进料速度对分选料成分影响不大,整体数据较稳定。
The substances separation in the food waste pretreatment stage has a great influence on the whole processing technology.If the sorting is not in place,there will be more impurities in the slurry,which will lead to the increase of equipment failure rate,pipe wear and other problems.The separation unit in the food waste pretreatment system was studied by reducing the rotating speed and feeding frequency of large substances separator.The results showed that with the decrease of rotation speed,the effect of sorting out large pieces of glass and ceramics could be achieved,the water content of the separation material had been increased but not obvious,the oil content rate would be increased,and there were some problems such as separating some organic substances,but there was no phenomenon of large amount of slurry being separated.With the increase of feed frequency,the content of separation material increased.The feeding speed had little influence on separation material composition and the overall data was stable.
