Abstract：Toaddressthe energy shortages problem，inadditionto developing newand renewable energy sources，the recoveryand utizationof waste heat resourceshavegained increasingatention，particularly low-grade industrial waste heat.Traditional ntegrated waste heat adsorption bedssufer from slow heat transferand uneven temperaturedistribution， severelylimitingtheeficiencyof waste heatstorage.Thisstudyproposesastaggeredadsorption bedthatutilizes thermocemical hydrationsalts for low-grade waste heat recovery.Results showthatthe heat-storagerateof thisadsorption bedis threetimes thatof traditionaladsorptionbeds.Intermsoftheheattransfer，itefectivelymitigates theissueof uneven heating durationof materialsacrosstheadsorptionbed.Intermsof themass transfer，amultidirectional mass transfer reducesthecontactimebetweenwatervaporandmaterials，avoidingconditionsforthesecondaryhydrationof heat-storage materials.Therefore，the“staggered adsorptionbed”has unique advantages inheat and masstransfer，providinganovel approach for the design and improvement of adsorption heat-storage beds for waste heat recovery.
