Considering the external size and the pressure drop requirement of the water cooling tower, a new cyclone designed to solve the problem. The new cyclone can be classified as a uniflow cyclone with a tangential inlet. It has an air inlet, a core, and an exit tube.There is three-dimensional swirl turbulent multiphase flow in gas-liquid cyclone separators and the separation of gas-liquid two-phase flow is a very complex process. The separation performance is influenced by many factors. First, in order to find the most appropriate operating conditions structure parameters, experiments were conducted to test the separation efficiency and pressure drop. Deduced the calculation formula of minimum separation work, reach the conclusion that when the mass concentration of15g/m3, the energy utilization ratio of cyclone separator was53.6%.Reynolds Stress mode was employed to calculate the velocity distribution and pressure distribution in the cyclone, for the reasonable interpretations and instructions of the experimental phenomena. By calculating the index of the tangential velocity, we found that the tangential velocity index was connected with the axial location, which is different from the tangential cyclone separator. The DPM model was used to numerical study the moving path of droplets. The droplet trajectory and separation efficiency for different diameter droplet were calculated in the optimal structure parameters and operating conditions.The research shows that there is a good agreement between the results of numerical simulation and experimental results. This paper provides valuable theoretical basis for production practice by analyzing the operating conditions and structure parameters influence on separation performance,...
