在高大平房仓管理中,由于数量限制等原因,常存在入粮高度达不到装粮线或半仓情况,使原本按装粮线高度设计的机械通风风网出现空气途径比>1.5,不能满足通风的需要。一些储粮单位曾做过支风道之间单管风机配合,或支风道正上方压盖聚乙烯薄膜的研究。但在实际工作中,单管风机能耗大,劳动强度大,通风不均匀、聚乙烯薄膜不易操作,效果不好。针对这一问题,我库进行了高大平房仓内低粮面通风降水降温的生产性试验。通过对多种方案的对比,探索出一套经济有效的通风方法,取得了良好的降水降温效果。
In the tall warehouse management, due to the number of restrictions and other reasons, there are often not enough grain into the grain or semi-barley loading situation, so that the height of the original installation of food machinery ventilation air network appears air route ratio> 1.5, can not Meet the needs of ventilation. Some grain storage units have done a single-tube fan between the branch duct, or branch duct just above the gland polyethylene film research. However, in practical work, the energy consumption of a single-pipe fan is large, labor intensity is large, ventilation is not uniform, and the polyethylene film is not easy to operate and the effect is not good. In response to this issue, I conducted a high-level storeroom warehouse ventilation and precipitation of low food production test. Through the comparison of various schemes, a set of economical and effective ventilation methods are explored, and good precipitation cooling effect has been achieved.
