摘要: 目前农作物秸秆主要通过水利碎浆机进行洗涤,具有功耗大、洗涤效果不好等缺点。本试验中设计了一种新型秸秆洗涤装置,并以小麦秸秆为原料对新型秸秆洗涤装置进行试验研究,主要考察了单因素搅拌转速、进水量以及进料速度对小麦秸秆含水量、洗涤机除杂率和洗涤装置单位产量功耗的影响。根据单因素的试验结果,对洗涤装置进行响应面优化,得到洗涤装置单位产量功耗最小的操作条件为:搅拌转速9.5r/min,进水量1.35倍于饱和进水量,进料速度1400kg/h。在此条件下对小麦秸秆进行洗涤,既能满足小麦秸秆含水量和洗涤机除杂率要求,又能使单位产量功耗最小,洗涤装置的综合效率最高。

关键词: 新型秸秆洗涤装置, 含水量, 除杂率, 单位产量功耗, 响应面

Abstract: Currently,the crop straw was washed by water aquapulper,which has the disadvantages of high power consumption and poor washing effect. In this experiment,a new straw washing device was designed,and the experiment was carried out with wheat straw. Experiments were conducted to study the influences on the wheat straw moisture content,impurity removing efficiency,power consumption per unit,by process parameters like agitator speed,water inflow and feed rate etc. According to single factor experiment results,we analyzed the washing device by response surface optimization. The results showed that power consumption per unit has a minimum value,when the agitator speed is 9.5r/min,water inflow 1.35 times saturated water inflow,feed rate 1400kg/h. The washing device can satisfy the requirement of wheat straw moisture content and impurity removing efficiency,and washing device has the highest comprehensive efficiency.

Key words: new straw washing device, moisture content, impurity removing efficiency, power consumption per unit, response surface
