For new type solid - liquid hydrocyclone's parameters in practice are unable to determine, the equipment often runs roughly, which often causes other related issues. It is necessary to establish its mathematical model to provide a theoretical basis for the actual operating parameters. Using fluid mechanics formula combined with TD Hardy Gang cylindrical cyclone model, we established a mathematical model of the new type of solid - liquid cyclone separator. By means of computer simulation, we obtained cyclone separator split ratio, flow - density - pressure and partition size - speed - pressure's three - dimensional diagram. The results show that, in actual working conditions, the cyclone separator's split ratio is approximate the same, partition size has a wide range, which is suitable for working in a variety of waters; on the condition that cyclone feed inlet velocity is about 5m/s, the discrete phase density and the traffic show local linear relationship and the flow field is stable.%新型导流式固-液旋流分离器在实际操作中存在参数无法确定的问题,设备经常跑粗.为了实际操作参数提供理论依据,并建立数学模型,运用流体力学公式结合T.D哈帝冈柱形旋流器模型建立了新型导流式固-液旋流分离器的数学模型.通过仿真,得出了旋流分离器的分流比、流量-密度-压强和分割尺寸-速度-压强等三维关系图.结果表明,实际工况中旋流分离器的分流达到近似固定值,分割尺寸范围广,适合在多种不同水域下工作.当旋流器的进料口速度在5m/s左右时,压强、离散相密度和流量呈局部线性关系且流场稳定.
