平地式储藏中的风管在平地式储粮堆中设计合适的通风管道情况较为复杂,尤其在容量较大的、具有由装卸造成的尖峰状粮堆中更是如此。通常采用表面起波纹的或平板的半园形、园形风管,风管表面开孔均匀,既方便又实用,这类管道常用16—20节板钢圈联接而成。储粮仓内风管既可以纵长安装,也可以纵横十字形安装,这取决于设计者的构思。存在波峰的粮堆中,粮堆各处深度不匀,要使通过粮堆的空气流取得一致就较困难。如果粮堆表
Air ducts in flat reservoirs It is more complicated to design suitable ventilation ducts in a land-based GRP, especially in larger capacity, spiked piles that result from loading and unloading. Usually corrugated or flat surface of the semi-circular garden, duct duct, duct surface openings evenly, both convenient and practical, commonly used in this type of pipe 16-20 section plate connected together. The bin inside the silo can be installed either vertically or horizontally, depending on the designer’s concept. In crest-filled mills, where the depth of the piles varies, it is more difficult to achieve consistency in the flow of air through the piles. If the food pile table
