摘要:
提出一种带预热的内热型除湿溶液再生器,基于NTU-Le模型建立了带预热的内热型逆流再生器传热传质数学模型,对比了预热型再生器与内热型再生器在不同工况下的再生性能,研究了内热分配比的变化对带预热的内热型再生器再生性能的影响. 模拟结果表明,内热型再生器与预热型再生器各具优势. 在设计带预热的内热型再生器时,投入热量较少时宜采用加热内热源作为再生热源的再生方式,投入热量较高时按照最佳内热分配比分别预热溶液和加热内热源的方式更节能. 当投入热量充足的情况下,qms/qma≤0.53时宜采用加热溶液作为再生热源的再生方式,qms/qma≥0.64时应按最佳内热分配比合理分配预热溶液和加热内热源的热量.
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.
