Abstract:
In this paper,an internal heat type desiccant solution regenerator with preheating is proposed. Based on NTU-Le model,a mathematical model of heat and mass transfer of internal heat type countercurrent regenerator with preheating is established. The regeneration performances of preheating type regenerator and internal heat type regenerator under different conditions are compared,and the influences of the change of internal heat distribution ratio on the regeneration performance of internal heat type regenerator with preheating are studied. The simulation results show that the internal regenerator and the preheated regenerator have their own advantages. When designing an internal heat regenerator with preheating,it is better to use heating internal heat source as regeneration heat source when the heat input is fewer. When heat input is higher,the optimal internal heat distribution is more energy-saving than preheating solution and heating internal heat source respectively. When the input heat is sufficient,the heating solution should be used as regeneration heat source when qms/qma≤0.53. When qms/qma≥0.64,the heat of preheating solution and internal heat source should be reasonably distributed according to the optimal internal heat distribution ratio.
