Other AbstractIn this paper, the flow of gas and solid in a standpipe system with aeration and a trickling valve at its bottom, is analyzed by the principle of particulate mechanics and multi-phase fluid mechanics. The working principle of the standpipe-trickling valve system is inquired. The correlation of the sealing height of standpipe and the solid flux with the structure factor of dipleg and operating conditions is theoretically analyzed. The quantitative relationship of aeration, gas backing flux, solid flux and structure factor of trickling valve system is stated under different conditions. A quantitative operating diagram is obtained. The diagram shows that the operating of a standpipe-trickling system would be divided into three regions. That are stable and no backing gas region, stable and backing gas region and non-operating region. theoretical analysis states that the non-fluidized flow regime goes against the stable operation, but the fluidized flow regime is propitious to the stable operation.
