对影响脉冲静压气力输送比的各种因素进行了分析.重点对发送罐的形状和装置以及连接方式进行了设计.实验中,以弯管和直管的压损、料长/气长之比等为主要参数进行了测量,结果表明,发送罐的设计和管道的布置更为合理,气密性更好.结果还表明,在发送罐初始压力相同的情况下,输送的煤粉量越多,输送比就越高;输送比μ和单位质量煤粉的输送时间成线性或分段线性关系。 The factors influencing the P / P ratio of impulse static pressure were analyzed, and the shape, device and connection mode of the sending tank were emphatically designed.In the experiment, the pressure loss of the bent pipe and the straight pipe, the length of material / gas The results showed that the design of the sending tank and the arrangement of the pipes were more reasonable and the air tightness was better.The results also showed that when the initial pressure of the sending tank is the same, More, the higher the delivery ratio; delivery ratio μ and unit mass of coal delivery time into a linear or piecewise linear relationship.
