一、单管通风的特点储粮单管通风属移动式粮堆机械通风,其原理是利用通风机运行中产生的压力,通过单一的管道起作用,将低温、低湿空气通入粮堆,以降低粮堆温度、水份,达到长期安全储藏的目的。与其它的机械通风方式比较,单管通风具有下列特点:1、通风效果好单管通风可以根据储粮的具体情况(粮食种类、粮堆大小、发热部位等)灵活、合理地设置风网。因风管单一,且空气交换的途径短,故管道内不存在空气压力不均匀的现象,风机压头损失也小。从降温速度、温度均衡性、能耗几个指标看,单管通风的
First, the characteristics of single-tube ventilation Storage grain single-tube ventilation is a mobile mechanical ventilation of grain piles, the principle is to use the pressure generated by the fan operation through a single pipe to work, the low temperature, low humidity air into the grain piles to Reduce the temperature of grain piles, water, to achieve the purpose of long-term safe storage. Compared with other mechanical ventilation, single tube ventilation has the following characteristics: 1, good ventilation effect Single tube ventilation can be based on the specific circumstances of stored grain (grain types, grain size, fever sites, etc.) flexible and reasonable set wind network. Due to the single duct and the short way of air exchange, there is no uneven air pressure in the duct, and the loss of the fan head is small. From the cooling rate, temperature balance, several indicators of energy consumption, single-tube ventilation
