Abstract: Liquid distributors which on the top the wet curtain are widely used in industry field especially in the packed tower and solution dehumidifier. Consequently, liquid distributors play a major role. Many scholars devote to design and analyze the performance of liquid distributor in order to improve distribute liquid capacity of the liquid distributor. The velocity or the flow of the outlet is very important for the performance of the liquid distributor which directly affects the performance of the solution dehumidifier, however, the velocity is difficult to quantify unless the flow field is known. Therefore outflow through the outlet of liquid distributors has been simulated using computational fluid dynamics (CFD) method. As first part of the project a new kind of liquid distributor which is used mine solution dehumidifier is proposed based on the related theory. In a second part of the project, through the Fluid-solid coupled simulation method, the velocity of the liquid distributor outlet and the stress of the orifice plate were analyzed based on the Fluid-solid coupled theory. The velocity and the stress were obtained which indicated that orifice plate liquid distributor had the well distribute liquid capacity. These results were validated by experimental results. In a third part of the project, the experiment was carried out to analyze the capacity of the orifice plate liquid distributor. In this paper, the performance of the liquid distributor of the mine solution dehumidifier was analyzed by the simulation and experimental methods, which provide a new idea and method for the design and analysis of distributor
