在高大房式仓机械通风网络中存在的“死角”问题极不利于粮食的安全储 藏。根据途径比理论，在“死角”部位设计并安装了一种辅助径向通风笼，取得很好的效 果。本文就通风笼的安装部位和尺寸进行了理论推算，对其在运用过程中的合理性和 科学性进行了探讨。
The problem of “dead ends” in the mechanical ventilating network of high-rise houses and houses is extremely unfavorable to the safe storage of grain. According to the path ratio theory, a kind of auxiliary radial ventilation cage was designed and installed in the “dead-end” part, which achieved good results. In this paper, the ventilation cage installation site and size of a theoretical calculation, its use in the process of rationality and scientific discussion.
