大直径筒仓横向通风设计的探讨

Dission on design of horizontal ventilation for large diameter silos

随着筒仓仓型的不断推广使用,筒仓的堆粮高度也在逐渐增高,常规的地槽正压机械通风也随着堆粮高度的增加,通风阻力越来越高,带来的温升问题也不容忽视,为适应高堆粮筒仓的通风降温使用需求,本文介绍了一种适用于高粮堆筒仓的通风系统,并具体分析其应用的优劣势。

With the continuous promotion and use of the silo type,the height of the silo is gradually increasing.The conventional positive pressure mechanical ventilation of the ground trough also increases with the increase of the height of the silo,and the ventilation resistance is getting higher and higher.In order to meet the needs of ventilation and cooling of high-grain silos,this paper introduces a ventilation system suitable for high-grain silos,and analyzes the advantages and disadvantages of its application.
