新型水-汽板式换热器的冷凝除湿性能研究
Condensation and Dehumidification Performance of a New Type of Water-steam Plate Heat Exchanger
摘要
Abstract
In wastewater treatment and petrochemical industries,condensation and dehumidification are often involved.Plate heat exchanger is gradually applied in the condensation and dehumidification process because of its compact structure,large heat exchange area in the unit volume and high heat transfer coefficient.However,due to the complexity of fluid flow and phase transition,it is difficult to study,calculate and analyze.The influence of heat transfer plate with different structural parameters on the performance of condensation dehumidification is studied by the combination of experiment and CFD numerical simulation.The results show that with the increase of heat transfer in wavy angle,boundary layer separation is more and more obvious,wet air has less moisture.With the increase of height of ripple,the flow dead zone is reduced,the fluid distribution is more uniform,The effect of condensation and dehumidification is enhanced.With the increase of the corrugation spacing,heat transfer plate the heat transfer area is reduced,turbulence degree is greatly reduced,and the effect of condensation and dehumidification becomes worse,but the pressure drop is effectively reduced.关键词
