摘要 对微小固体颗粒在密相气力输送情况下进行试验,研究输送压力最高可达0.5 MPa的输送过程中,输送系统的罐压、背压和粉量调节阀的开度以及流化风量和载气流量分别对固气比的影响。结果表明:差压增大会导致固气比增大;粉量调节阀开度增大,有助于固气比提高;适当增大流化风量或载气流量可提高固气比,达到峰值后,固气比会随着流化风量或载气流量的增大而减小,固气比达到峰值时对应的流化风量、载气流量为最佳值。 Experiments of dense-phase pneumatic conveying of tiny solid granule with air were carried out in an experimental facility with the conveying pressure up to 0.5 MPa. The influences of the tank pressure, the back pressure, the opening degree of regulating valve, the fluidization air flow rate, the cartier gas flow rate on the solid-gas ratio were investigated. The test results indicate that with the increases in total conveying pressure drop or the opening degree of regulating valve, the solid-gas ratio increases, with the increases in fluidization air flow rate or the carrier gas flow rate, the solid-gas ratio increases at first and then declines. When the solid-gas ratio is max, the corresponding fluidization air flow rate or the carrier gas flow rate are the optimal.
