Abstract

Abstract:

To address the energy shortages problem, in addition to developing new and renewable energy sources, the recovery and utilization of waste heat resources have gained increasing attention, particularly low-grade industrial waste heat. Traditional integrated waste heat adsorption beds suffer from slow heat transfer and uneven temperature distribution, severely limiting the efficiency of waste heat storage. This study proposes a staggered adsorption bed that utilizes thermochemical hydration salts for low-grade waste heat recovery. Results show that the heat-storage rate of this adsorption bed is three times that of traditional adsorption beds. In terms of the heat transfer, it effectively mitigates the issue of uneven heating duration of materials across the adsorption bed. In terms of the mass transfer, a multidirectional mass transfer reduces the contact time between water vapor and materials, avoiding conditions for the secondary hydration of heat-storage materials. Therefore, the “staggered adsorption bed” has unique advantages in heat and mass transfer, providing a novel approach for the design and improvement of adsorption heat-storage beds for waste heat recovery.

Key words: low-grade waste heat, hydrated salts, heat storage, heat and mass transfer
