Simulation Experimental Study Of Condenser In Zinc Refinery

How to effectively condensing zinc vapor into liquid in condenser influences the development of zinc refinery technology all through. There is insufficient data in existing references about the thermodynamics properties of zinc vapor. Dimensional equations attained from the study of condensation usually aim at revolving or tabulating cooling surface. The error is large. It is difficult to use these equations directly for condenser design, thus it is important and necessary to study the structure properties of zinc refinery condenser by simulation experimentsIn order to effectively analyzing the influence of the structure characteristics of condenser on the process of condensation, the dissertation synthesized the constraint conditions of field N technique and simulation computation of condenser , and established a structural model. A set of feasible Pilot models and integrated steam/water experimental system had been set up according to the reliability of experimental results, and stimulation experiments had been conducted for comparison. The study checked thermal equilibrium and results, analyzed relative error and error limit. The results of these comparative experiments show that under a given pressure for liquid_encapsulated the volume of a condenser obviously affects the condensation. And it is unfeasible for a condenser to only add its external area, without considering its aspect ratio. A reasonable aspect ratio is beneficial for keeping well-proportioned distribution of condensation intensity. According to the results of these experiments, and taking into consideration of some uncertain factors, the best aspect ratio is approximately 1.15; The results of these comparative experiments also show that the position of steam intake almost has no influence on condensation quantity, but the change of the position of steam intake will obviously affect the well-proportioned distribution of condensation intensity. When the intake is placed in the middle of the condenser in the vertical direction, the temperature distribution of condenser wall is uniform, the difference in temperature of a single wall is small, which will be in favor of reducing thermal stress and improving the longevity of the use of condenser.
