| 摘 要： | 为了提高餐厨垃圾中废油脂分离回收效率,采用湿热-离心法分离餐厨废油脂,通过试验探讨了加热时间、温度以及离心转速等处理参数对餐厨废油脂分离回收效率的影响；同时,将其与湿热-重力法进行比较,以确定有利于餐厨废油脂分离回收的适宜工艺条件. 结果表明:湿热-离心法较湿热-重力法更有利于餐厨废油脂的分离；随着温度升高和加热时间延长,餐厨垃圾脱油性能呈上升趋势,温度越高,趋势越明显；120 ℃下湿热处理80 min,餐厨垃圾固相内部油脂液化浸出效果最佳,最佳离心转速为2 500 r/min时,餐厨垃圾废油脂分离回收率最高.

| Abstract: | Hydrothermal process-centrifugation was used to improve the recovery rate of waste grease from restaurant garbage.The effects of heating time,temperature and centrifugation speed on the recovery rate of waste grease from the restaurant garbage were investigated by experimentation.At the same time,appropriate technological conditions suitable for waste grease recovery from restaurant garbage were defined through comparison with the hydrothermal process-gravitation process.The results showed that the hydrothe... |
